Strategy Specifications

Deck Name And Archetype

• Identity: Dimir Excruciator is registered as a 60-card Standard blue-black midrange-control deck with a graveyard tag and a 15-card sideboard. The name implies Doomsday Excruciator is the defining top-end or engine card, while Duress, Bitter Triumph, Day of Black Sun, Deadly Cover-Up, Requiting Hex, Stock Up, Insatiable Avarice, and Strategic Betrayal point toward discard, removal, sweepers, card flow, and attrition rather than pure tempo.

• Registration validation: The submitted main deck totals exactly 60 cards, and the submitted sideboard totals exactly 15 cards. The apparent land package is 26 cards if Restless Reef, Swamp, Cavern of Souls, Multiversal Passage, Undercity Sewers, Watery Grave, and Gloomlake Verge are all treated as lands; Veles should still trust runtime type and mana data over this guide if the rules engine classifies any of those differently.

• Tag validation: Normalize the duplicated submitted tags to midrange, control, and graveyard. Runtime role selection should begin as Dimir attrition-control, then shift toward midrange pressure only when legal actions show Superior Spider-Man, Doomsday Excruciator, Restless Reef, or Emeritus of Ideation can close faster than holding interaction.

• Stock status: Treat this list as rogue or hybrid, not stock, unless a current external metagame source identifies this exact 75. The mixture of Doomsday Excruciator, Superior Spider-Man, Requiting Hex, Winternight Stories, Day of Black Sun, Stock Up, Emeritus of Ideation, and a sideboard with Oildeep Gearhulk, Quantum Riddler, and Sunderflock looks tuned around a specific Standard card pool rather than a familiar published Dimir shell.

• Format validation: Format is declared Standard, but current legality requires authoritative validation before sanctioned or high-confidence testing. Watery Grave, Cavern of Souls, Flashfreeze, Duress, and the newer-looking named cards may be legal only if their current printings are Standard-legal; Veles should report a legality concern until the deck is checked against the active rules engine or card database.

• Card-text caution: Card text check required for Doomsday Excruciator, Restless Reef, Deceit, Winternight Stories, Superior Spider-Man, Day of Black Sun, Requiting Hex, Stock Up, Strategic Betrayal, Emeritus of Ideation, Multiversal Passage, Gloomlake Verge, Decorum Dissertation, Qarsi Revenant, Oildeep Gearhulk, Quantum Riddler, and Sunderflock before any deterministic rules-text claim is trusted. Known-looking cards such as Duress, Bitter Triumph, Deadly Cover-Up, Insatiable Avarice, Ghost Vacuum, Flashfreeze, Watery Grave, and Cavern of Souls should still follow engine-exposed legal actions at runtime.

• Mana concern: The deck appears heavily black with blue support, but Cavern of Souls can create color tension if noncreature interaction must be cast on curve. Opening-hand evaluation should verify black for discard/removal, blue for Stock Up or other blue spells, and enough untapped mana to interact before assuming a slow Dimir hand is keepable.

• Role concern: The maindeck nonland cards with 2+ copies that must receive full tactical coverage are Doomsday Excruciator, Deceit, Duress, Winternight Stories, Bitter Triumph, Superior Spider-Man, Day of Black Sun, Requiting Hex, Stock Up, and Insatiable Avarice. The sideboard cards requiring later Sideboard Map and matchup coverage are Strategic Betrayal, Decorum Dissertation, Qarsi Revenant, Ghost Vacuum, Duress, Oildeep Gearhulk, Quantum Riddler, Flashfreeze, and Sunderflock.

• Opponent information status: No opponent decklist, matchup label, play/draw assignment, revealed cards, or metagame target is supplied. Game 1 should use unknown-opponent Dimir principles and upgrade to matchup-specific guidance only from public information such as visible colors, graveyard use, creature density, stack interaction, planeswalker or artifact/enchantment reliance, sweepers, or fast pressure.

Thesis

• Assemble attrition first, closure second: Dimir Excruciator wants to build a game where early discard, removal, sweepers, and card flow trade down the opponent's best starts, then a small number of durable threats or payoff spells finish after the opponent is low on resources. Prioritize black mana, early legal interaction, and card-flow turns that do not expose the deck to a lethal board.

• Win through controlled inevitability, not explosive certainty: Doomsday Excruciator, Superior Spider-Man, Restless Reef, Emeritus of Ideation, and possibly Requiting Hex are the likely closing tools, but Card text check required for their exact functions. Treat each as a finisher only when the engine exposes legal actions and visible board state supports either stabilizing first or ending the game before the opponent rebuilds.

• Protect the long game by sequencing discard before commitment: Duress and Strategic Betrayal should clear or identify opposing interaction before tapping low for Doomsday Excruciator, Superior Spider-Man, Emeritus of Ideation, or a large card-flow turn. If the opponent is presenting lethal or a short clock, survival actions outrank information-gathering discard unless the discard is the only legal way to prevent the key threat.

• Use velocity as a bridge, not a vacation: Stock Up, Winternight Stories, Insatiable Avarice, and Deceit should convert spare mana into action density, but they should not replace a needed Bitter Triumph, Day of Black Sun, Deadly Cover-Up, or Requiting Hex when the board is already dangerous. Card text check required for Stock Up, Winternight Stories, and Deceit, so runtime legal modes and visible costs decide exact sequencing.

• Avoid pretending to be tempo or pure combo: this deck is not trying to spend every turn attacking at maximum speed, hold up interaction forever without advancing, or commit a fragile top-end card into known disruption. The preferred pattern is interact, reload, interact again, then deploy one threat with enough life total, mana, and public information to force the opponent into bad topdecks.

• Prioritize runtime legality over strategic preference: if Veles legal actions do not show a cast, target, attack, block, or activation line, the guide must not assume it exists. If visible information contradicts a general role rule, choose the legal action that addresses the visible board, stack, life total, mana, graveyard, and known revealed cards.

Role Package

• Threats: Doomsday Excruciator is the named build-around and likely primary top-end threat; Card text check required, so commit only when the board is stable, the opponent's key answer is stripped or taxed, or waiting risks losing inevitability. Superior Spider-Man is a four-copy threat or stabilizer by registration priority; Card text check required, but four copies means it should be evaluated as a central battlefield plan rather than a rare finisher. Restless Reef is a registered four-copy land threat if runtime confirms creature-land functionality; use it to pressure after sweepers or in stalled games while preserving spell mana when interaction is required. Emeritus of Ideation is a singleton threat or engine; Card text check required, so treat it as high-upside but not essential to opening-hand keeps.

• Payoffs: Requiting Hex appears as a four-copy payoff or interaction spell and should be treated as a key conversion card once the opponent's board, life total, or resources make its legal action impactful; Card text check required before assuming damage, drain, removal, or graveyard scaling. Deadly Cover-Up is the singleton reset or attrition payoff; use it when the visible board requires a wide answer or when a sweeper creates a safer path for Doomsday Excruciator, Superior Spider-Man, or Restless Reef.

• Engines: Winternight Stories, Stock Up, Insatiable Avarice, Strategic Betrayal, and Emeritus of Ideation are the likely card-advantage or selection engines. Use them when mana would otherwise be inefficient, when the hand lacks the next land or answer, or after the opponent's immediate threat has been answered; do not cast them into visible lethal pressure unless the legal action directly finds or creates survival.

• Velocity: Stock Up and Insatiable Avarice are the most explicit reload cards, while Deceit and Winternight Stories may be filtering, interaction, or advantage depending on verified text. Favor velocity in low-pressure turns, mulligan recovery, and post-trade windows; delay it when the opponent has a must-answer permanent or stack threat.

• Interaction: Duress, Bitter Triumph, Day of Black Sun, Deadly Cover-Up, Requiting Hex, Strategic Betrayal, Flashfreeze, Sunderflock, Ghost Vacuum, and possibly Decorum Dissertation form the disruption suite. Spend discard on noncreature engines, sweepers, counters, and planeswalker-style threats when visible; spend removal on threats that shorten the clock or invalidate future sweepers.

• Protection: Duress protects commitments before they happen, Cavern of Souls may protect creature casts if runtime confirms relevant creature types and mana legality, and sideboard Flashfreeze or Sunderflock can protect against specific stack or permanent classes if their legal actions appear. Never assume protection from card names alone.

• Recursion and graveyard module: The deck is tagged graveyard, but Card text check required for which registered cards actually use graveyards. Treat Deadly Cover-Up, Ghost Vacuum, Qarsi Revenant, Oildeep Gearhulk, and Doomsday Excruciator as conditional graveyard-relevant cards only when engine text or legal actions expose graveyard choices.

• Mana module: Swamp, Watery Grave, Gloomlake Verge, Undercity Sewers, Restless Reef, Cavern of Souls, and Multiversal Passage must support black early and blue by the first meaningful card-flow turn. Keep mana flexible for Bitter Triumph, Duress, Day of Black Sun, Stock Up, and sideboard counters rather than overusing creature-land or specialty-land lines.

• Sideboard modules: Duress, Strategic Betrayal, Flashfreeze, and Sunderflock increase stack or hand interaction; Ghost Vacuum addresses graveyards; Qarsi Revenant, Oildeep Gearhulk, and Quantum Riddler add threat, recursion, or anti-control density if their text supports it; Decorum Dissertation is a singleton specialized tool requiring card-text verification before role assignment.

Primary Win Conditions

• Top-end threat conversion with Doomsday Excruciator: Set up by trading resources early with Duress, Bitter Triumph, Day of Black Sun, Requiting Hex, and Deadly Cover-Up, then commit Doomsday Excruciator when the visible board is stable or the opponent is low on known answers. Card text check required, so execution depends on the engine's legal action text: if it is a creature threat, protect the attack window; if it is a graveyard or library payoff, do not start the line unless the relevant zone state is visible and legal choices are available. Prioritize this path when the opponent is topdecking, when Cavern of Souls can legally support the cast, or when waiting lets the opponent rebuild a wider battlefield than your sweepers can manage.

• Four-copy battlefield pressure with Superior Spider-Man: Set up by using discard and removal to force a clean battlefield, then deploy Superior Spider-Man as the repeatable threat or stabilizer that asks the opponent to answer on board. Card text check required, so do not assume evasion, removal, lifegain, or protection; use only visible combat stats, keywords, legal attacks, legal blocks, and engine prompts. Prioritize this line against opponents whose resources are already reduced by Duress, Strategic Betrayal, or attrition, and deprioritize it when tapping out would leave a lethal attack, unhandled stack threat, or must-answer permanent.

• Attrition-to-finisher line with Requiting Hex: Treat Requiting Hex as a core conversion card because it appears as four main-deck copies, but Card text check required for whether it removes, drains, burns, scales, or creates another payoff. Set up by preserving life and trading one-for-one until a legal Requiting Hex action materially changes the board or clock. Execute only from visible legal action text, especially for target choice, cost, and any graveyard or life-total dependency. Prioritize this line when it answers the opponent's best visible threat while advancing your own clock, or when it converts a stalled board into a win without exposing Doomsday Excruciator first.

• Post-reset creature-land pressure with Restless Reef: Use Restless Reef as the default fallback closer after Day of Black Sun or Deadly Cover-Up clears the board, if runtime confirms a legal activation and combat action. Set up by making land drops and keeping enough black-blue mana to represent interaction after activation. Execute by attacking only when the attack does not surrender necessary blockers, removal mana, or a safer top-end commitment. Prioritize this line against depleted opponents and in games where main threats were removed, countered, discarded, or cannot be safely committed.

Secondary Win Conditions

• Card-flow inevitability wins through Stock Up, Winternight Stories, Insatiable Avarice, Deceit, and Emeritus of Ideation when the game becomes resource-bound. Card text check required for each exact selection or draw mode, so use them as legal-action reloads rather than assumed tutors. The tactical goal is to keep making land drops, find the next answer, and chain enough material that any surviving Superior Spider-Man, Doomsday Excruciator, Restless Reef, or Requiting Hex becomes decisive.

• Singleton high-upside pressure from Emeritus of Ideation is a backup engine or threat, not a plan to mulligan toward. Commit it after the opponent's known interaction is reduced or when your hand lacks another path to pull ahead. If the engine exposes selection, card advantage, graveyard, or combat-relevant choices, use visible board pressure and known resources to decide whether Emeritus of Ideation is a stabilizer, a threat, or a value engine.

• Graveyard-oriented side or late-game pressure is conditional on verified text from Doomsday Excruciator, Deadly Cover-Up, Ghost Vacuum, Qarsi Revenant, and Oildeep Gearhulk. Do not assume recursion, exile, reanimation, or graveyard scaling unless Veles exposes the legal action and target set. When the graveyard plan is live, favor it in exhausted games where both players have traded removal and creatures, but avoid overcommitting graveyard resources into visible opposing graveyard hate or stack interaction.

• Disruption-lock wins come from repeated information and answer compression with Duress, Strategic Betrayal, Bitter Triumph, Day of Black Sun, and Deadly Cover-Up. This is not a hard lock unless card text proves one; it is a tactical squeeze where the opponent has fewer relevant plays than you have answers. Prefer this route when the opponent's hand is known, their board is contained, and your own threat can wait one turn without losing inevitability.

Emergency Lines

• When behind on life, stop spending turns on pure velocity unless the legal action directly finds or creates survival. Use Bitter Triumph, Day of Black Sun, Deadly Cover-Up, and any legal Requiting Hex removal or life-swing mode before Stock Up, Winternight Stories, Insatiable Avarice, or Deceit if the visible clock is short. Attack with Restless Reef or creatures only when the crackback is not lethal or when racing is the only visible route.

• When behind on board, prioritize sweepers and high-impact removal over discard. Day of Black Sun and Deadly Cover-Up should be held for multi-threat boards when possible, but cast them earlier if waiting makes them too slow or if a single protected threat will end the game. Use Bitter Triumph on the threat that most reduces future survival, not merely the largest creature.

• When behind on cards, convert spare mana into Stock Up, Winternight Stories, Insatiable Avarice, Deceit, or Emeritus of Ideation only after the current battlefield and stack are not killing you. If the opponent has no immediate pressure, prioritize the reload that best hits land drops and interaction according to legal modes and visible costs.

• When behind on mana, keep hands and lines that cast black interaction early and reach blue card flow later. Do not activate Restless Reef, overuse Cavern of Souls, or take speculative specialty-land lines if they prevent casting Duress, Bitter Triumph, Day of Black Sun, or Stock Up on curve.

• When win conditions are removed, pivot to land and attrition pressure. Restless Reef becomes the cleanest fallback if legal, Requiting Hex becomes the best conversion spell if text supports it, and card-flow spells should be aimed at finding any remaining Doomsday Excruciator, Superior Spider-Man, Emeritus of Ideation, or sideboard threat. Avoid conceding strategic direction just because the first finisher is gone; the deck is built to win after multiple trades.

• When the opponent is executing a faster engine, graveyard plan, or combo, treat Duress, Strategic Betrayal, Flashfreeze, Sunderflock, Ghost Vacuum, and fast pressure as emergency tools after sideboarding. Use only visible hand, stack, graveyard, and legal target information; if the hate or permission spell is not legally exposed, choose the best available survival or clock action instead.

Resource Model

• Life is a spendable buffer only when the board is controlled. Treat Watery Grave, Bitter Triumph, and Insatiable Avarice as possible life-pressure decisions; Card text check required for exact costs and modes, so decline life payments when the visible clock makes the next attack or burn sequence dangerous.

• Cards in hand are the deck's main stabilizing resource. Use Duress and Strategic Betrayal to convert one card into information plus disruption, and use Stock Up, Winternight Stories, Deceit, Insatiable Avarice, and Emeritus of Ideation to rebuild only after the stack and battlefield are not forcing an answer.

• Mana is the gate between control and inevitability. Prioritize land drops through turn five because Day of Black Sun, Deadly Cover-Up, Doomsday Excruciator, Superior Spider-Man, Requiting Hex, and sideboard threats are strongest when Veles can still hold interaction or activate Restless Reef after the main play.

• Board presence should be exchanged, reset, then converted into pressure. Use Bitter Triumph, legal Requiting Hex modes, Day of Black Sun, and Deadly Cover-Up to reduce opposing pressure before committing Doomsday Excruciator, Superior Spider-Man, Emeritus of Ideation, Oildeep Gearhulk, Quantum Riddler, or Qarsi Revenant.

• Graveyard and exile are conditional resources, not assumed engines. Card text check required for Doomsday Excruciator, Deadly Cover-Up, Ghost Vacuum, Qarsi Revenant, and Oildeep Gearhulk; use graveyard or exile actions only from visible legal targets, and avoid spending graveyard material casually if a later legal payoff is exposed.

• Lands are both mana and late-game action density. Restless Reef should be preserved as a post-answer threat when possible, while Cavern of Souls, Undercity Sewers, Multiversal Passage, Gloomlake Verge, Watery Grave, and Swamp should be sequenced to cast early black interaction without locking out blue selection.

• Sacrifice fodder is not a primary plan. If Bitter Triumph or another legal action asks for sacrifice or discard, prefer expendable permanents or low-impact cards only after comparing visible board needs, future land drops, and whether the discarded card is required for stabilization.

• Tempo is gained by spending mana on the current choke point. Against pressure, answer creatures before drawing; against slow hands revealed by Duress, spend early turns on development and selection; against stack-based threats after sideboarding, preserve mana for Flashfreeze or Sunderflock when their legal action text is live.

• Information is worth most before irreversible commitments. Cast Duress or Strategic Betrayal before tapping out for Doomsday Excruciator, Superior Spider-Man, Emeritus of Ideation, or a sweeper when both actions are legal and mana supports the sequence.

• Sideboard bullets convert narrow windows into high leverage. Ghost Vacuum is for visible graveyard pressure, Flashfreeze and Sunderflock are for legal stack or permanent interaction, Decorum Dissertation is conditional on verified text, and extra threats like Oildeep Gearhulk, Quantum Riddler, and Qarsi Revenant should replace weaker pacing cards only when their role matches the matchup plan.

Mana Guide

• Keep hands that cast black interaction early and blue card flow later. A strong opener usually has two or three lands, at least one black source for Duress, Bitter Triumph, or Day of Black Sun, and a path to blue mana for Stock Up, Deceit, Winternight Stories, Superior Spider-Man, or sideboard Flashfreeze.

• Mulligan hands that cannot produce black mana before the opponent can establish pressure. Cavern of Souls, Restless Reef, Multiversal Passage, or color-conditional lands are not enough if they leave Duress, Bitter Triumph, and Day of Black Sun stranded and no legal early play stabilizes.

• Sequence tapped or setup lands before interaction turns when the visible board allows it. Lead with Undercity Sewers, Restless Reef, or any land Veles exposes as entering tapped when no immediate black spell is needed; play untapped Swamp or Watery Grave when the turn requires Duress or Bitter Triumph.

• Use Watery Grave life payment only when the current turn matters. Pay life to cast a decisive discard spell, removal spell, counterspell, sweeper, or selection spell on curve; let it enter tapped when the mana is not needed and the opponent's visible clock punishes unnecessary life loss.

• Treat Cavern of Souls as a utility land with color risk. Use it to support creature commitments only when the named type and legal spell matter; do not keep or sequence it in a way that prevents noncreature spells such as Duress, Bitter Triumph, Day of Black Sun, Deadly Cover-Up, Stock Up, Requiting Hex, or sideboard interaction.

• Preserve double-color access before expensive turns. Card text check required for exact costs, but the registered mix implies black-heavy control plus blue support; by midgame, prefer land lines that enable both black removal/sweepers and blue selection rather than maximizing creature-only or activation mana.

• Play lands before draw or selection when the land drop is required for a known legal action this turn. If casting Stock Up, Winternight Stories, Deceit, or Insatiable Avarice could reveal a better land and the current land is not needed for the spell, consider drawing first only when Veles still permits the land play afterward.

• Hold lands only for explicit value or discard protection. In normal games, make land drops to reach Doomsday Excruciator, Deadly Cover-Up, Superior Spider-Man, Emeritus of Ideation, Restless Reef activation, and sideboard threats; hold an extra land when the hand already has enough mana and a legal discard, selection, or bluff context rewards it.

• Spend mana on Restless Reef cautiously. Activate or attack with it when the legal action advances a safe clock, but keep mana untapped instead when interaction, sweepers, stack responses, or post-combat survival are more important than land-creature damage.

Mulligan Guide

• Strong keeps have two or three lands, early black interaction, and a real turn-three or turn-four plan. Keep hands like Swamp, Watery Grave, Gloomlake Verge, Duress, Bitter Triumph, Stock Up, Doomsday Excruciator because they disrupt, answer the first threat, hit blue card flow, and progress toward the top end.

• Strong control keeps contain discard plus a sweeper or reset when the mana supports it. Keep Swamp, Undercity Sewers, Watery Grave, Duress, Day of Black Sun, Requiting Hex, Deceit against creature pressure if Veles shows black mana on time; Card text check required for Day of Black Sun, Requiting Hex, and Deceit, so treat the hand as strong only when legal actions confirm they interact or develop as expected.

• Medium keeps have interaction plus selection but need one draw step to become excellent. Keep two-land hands with Duress, Stock Up, Deceit, or Winternight Stories when at least one land casts early black spells and the second land gives or implies blue access; ship if both lands enter tapped and the opponent is already known as fast.

• Medium threat-heavy keeps are acceptable on the play against slow decks. A hand with three lands, Duress, Superior Spider-Man, Doomsday Excruciator, and Insatiable Avarice can keep if discard clears the way and life total is not under immediate pressure; on the draw against aggro, this hand needs Bitter Triumph, Day of Black Sun, or a legal early stabilizer.

• Risky keeps rely on Restless Reef, Cavern of Souls, or Multiversal Passage to fix early turns. Keep only if Veles exposes enough colored mana to cast at least one of Duress, Bitter Triumph, Deceit, or Stock Up before turn three; otherwise mulligan because this deck cannot afford stranded interaction.

• Automatic ships have zero or one land, five or more lands without action, no black source, or no castable spell before turn three. Ship hands where Cavern of Souls is the only relevant colored source for noncreature spells, hands full of Doomsday Excruciator, Superior Spider-Man, and Emeritus of Ideation without early plays, and hands that depend on unknown card text from Requiting Hex or Winternight Stories to survive.

• Matchup-dependent keeps change after sideboarding. Against stack or green/red strategies, a hand with Flashfreeze can keep if it has blue mana and enough early survival; against graveyard pressure, Ghost Vacuum is a keepable role card only with normal lands and interaction; against attrition, extra Strategic Betrayal, Qarsi Revenant, Quantum Riddler, or Oildeep Gearhulk can justify slower hands after their card text and legal roles are verified.

• Play/draw adjustment is about time to stabilize. On the play, keep more Duress plus selection hands because the first discard can protect a turn-three Stock Up or turn-four threat; on the draw, require Bitter Triumph, Day of Black Sun, Requiting Hex, or a verified blocker when the opponent can apply early pressure.

• Trap hands look powerful but fail the first battlefield test. Do not keep four-land hands with only expensive cards, double Insatiable Avarice hands that pay life without stabilizing, or hands where Watery Grave must shock only to cast a nonessential draw spell while the opponent's visible clock is fast.

Turn Arc

• Turn 1 prioritizes black source plus information. Cast Duress when legal against unknown, combo, control, or removal-heavy opponents; otherwise play the land that best supports turn-two Bitter Triumph, Deceit, Stock Up, or Winternight Stories, letting Watery Grave enter tapped when no immediate spell matters.

• Turn 1 deviations preserve life and colors. Lead Swamp for Duress or removal, lead Undercity Sewers or Restless Reef only when Veles shows no urgent spell, and avoid Cavern of Souls first if it strands Duress, Bitter Triumph, Day of Black Sun, Requiting Hex, or Stock Up.

• Turn 2 answers pressure before drawing cards. Use Bitter Triumph or a legal Requiting Hex action on a threatening creature or engine if the opponent is developing quickly; use Deceit, Winternight Stories, Stock Up, or Insatiable Avarice only when the board does not require immediate removal and life payment is safe.

• Turn 2 deviations protect future turns. Cast Duress before a planned turn-three setup spell when the opponent kept mana-heavy or interaction-heavy hands, and hold removal if the only visible target is low impact while a known higher-impact threat is likely but not guaranteed.

• Turn 3 is the first stabilization checkpoint. Prefer Day of Black Sun or verified Requiting Hex interaction when multiple opposing permanents threaten life total, prefer Stock Up or Deceit when the battlefield is stable, and commit Superior Spider-Man only if legal text and visible state make it a stabilizer rather than an unprotected tempo loss.

• Turns 4-5 convert parity into inevitability. Sequence Duress or Strategic Betrayal before tapping out for Doomsday Excruciator, Superior Spider-Man, Emeritus of Ideation, or Deadly Cover-Up when both are legal; use Day of Black Sun or Deadly Cover-Up to reset wide boards before deploying expensive threats.

• Turns 4-5 deviations depend on open mana and known information. Hold up Bitter Triumph, sideboard Flashfreeze, or Sunderflock when Veles exposes a live response window against a decisive spell, but tap out for Doomsday Excruciator or Oildeep Gearhulk when waiting lets the opponent rebuild or when discard has cleared the path.

• Late game turns lands into threats and extra cards into dominance. Activate or attack with Restless Reef after sweepers when interaction remains covered, chain Stock Up, Winternight Stories, Deceit, or Insatiable Avarice to find action, and spend Doomsday Excruciator, Superior Spider-Man, Emeritus of Ideation, Qarsi Revenant, Quantum Riddler, or Oildeep Gearhulk as finishers only through legal actions that do not expose a lethal counterattack.

• Late game deviations favor survival over elegance. If life total is low, stop paying life for Watery Grave, Bitter Triumph, or Insatiable Avarice unless the action prevents a worse visible outcome; if graveyard or exile decisions appear, choose only from visible legal targets and require Card text check required for payoff assumptions involving Doomsday Excruciator, Qarsi Revenant, Ghost Vacuum, or Oildeep Gearhulk.

Card Roles

• Doomsday Excruciator is the primary late-game commitment card, not an early stabilization spell unless Veles shows it has defensive text. Card text check required, so cast it after discard, removal, or a sweeper has reduced the opponent's ability to punish a tap-out; hold it when the visible board already demands Bitter Triumph, Day of Black Sun, Requiting Hex, or Deadly Cover-Up first.

• Superior Spider-Man is a major midgame board card that should bridge control turns into pressure. Card text check required, so treat it as a castable threat or stabilizer only when legal action text and visible stats confirm it affects combat, blocks profitably, removes pressure, or generates value; do not spend it into open removal when Duress or Strategic Betrayal can clear the way first.

• Duress is the cleanest protection and information spell. Cast it early against unknown, control, combo, and removal-heavy opponents; save it in midgame when the hand already curves and the next strategic decision is whether to commit Doomsday Excruciator, Superior Spider-Man, Emeritus of Ideation, Deadly Cover-Up, or a sideboard finisher. Take the card that beats the current plan, not the card with the highest generic power.

• Bitter Triumph is premium targeted interaction with a real cost. Use it on creatures or planeswalkers that threaten life total, snowball resources, or invalidate a sweeper plan; prefer discarding excess lands, redundant expensive cards, or dead situational spells over paying life when under pressure. Do not fire it at a low-impact attacker if Day of Black Sun, Requiting Hex, or Deadly Cover-Up is likely to answer multiple threats next turn.

• Day of Black Sun is a high-priority stabilization card when legal text confirms it removes or weakens opposing boards. Card text check required; if Veles exposes it as mass removal, use it before deploying creature threats and delay it when one more turn can catch a second creature without risking lethal. Do not assume it kills everything unless the rules engine shows the resulting legal effect or known card text has been verified.

• Requiting Hex is a four-copy interaction or swing slot that deserves early legal-text inspection. Card text check required; if Veles shows it as removal, life swing, curse, or attrition effect, prioritize it where it changes the clock or clears the way for Superior Spider-Man and Doomsday Excruciator. Avoid building a keep or line around it when the current action text does not confirm its tactical function.

• Deceit is a four-copy early-game glue card whose exact job must be confirmed from legal actions. Card text check required; if it is discard, selection, tempo, or removal, use it to smooth the first three turns and protect higher-impact plays. Do not cast it automatically into an empty or low-impact window if holding it could answer a known class of follow-up revealed by Duress.

• Stock Up is the main blue card-advantage and selection role. Cast it when life total and battlefield are stable enough to spend mana finding the next answer or threat; prioritize it after one-for-one trades to reload into Bitter Triumph, Day of Black Sun, Requiting Hex, or a finisher. Do not take a slow card from a selection prompt when the visible board requires immediate removal or a blocker.

• Winternight Stories is a two-copy value or selection spell with conditional tactical use. Card text check required; treat it as a setup spell when the board is quiet and as a hold when mana must stay open for Bitter Triumph, Requiting Hex, sideboard Flashfreeze, or Sunderflock. If legal choices involve graveyards, cards drawn, or life payment, choose the mode that keeps the deck alive before maximizing long-game value.

• Insatiable Avarice is a flexible late setup card, but its life and tempo costs matter. Use it to find a missing land, sweeper, removal spell, or finisher when the current board allows a sorcery-speed action; avoid the draw-three style line at low life unless it finds an answer immediately or the alternative loses to visible pressure. When choosing between top-deck tutoring and raw cards, favor the option that solves the next turn cycle.

• Deadly Cover-Up is the main one-copy reset and graveyard-sensitive control card. Cast it when the opponent has overcommitted or when a single-target answer will not stabilize; hold it if your own Superior Spider-Man, Doomsday Excruciator, or Emeritus of Ideation is winning combat and the opponent's board is contained. If collect-evidence or graveyard-exile decisions appear, use only visible graveyard information and avoid exiling cards needed by confirmed friendly effects.

• Strategic Betrayal is a one-copy disruption or swing card that should be sequenced around commitment turns. Card text check required; use it before tapping out if legal text shows hand attack, removal, theft, or resource denial, and do not rely on it as a universal answer without rules-engine confirmation. Its sideboard copy means Game 2 and Game 3 plans can increase this effect when the matchup rewards the verified role.

• Emeritus of Ideation is a singleton top-end value card. Card text check required; cast it when the game is stable enough for a value permanent or when its visible legal text immediately affects the board. Do not expose it before sweepers if the current plan is to reset the battlefield with Day of Black Sun or Deadly Cover-Up.

• Restless Reef is both mana and a late-game threat. Prioritize it as a land early when tapped timing does not block Duress, Bitter Triumph, Deceit, or Stock Up; activate it after sweepers or during stalled boards only when Veles shows enough mana remains for interaction or no relevant response is needed. Do not animate it into obvious profitable blocks unless the exchange protects life or closes the game.

• Watery Grave, Gloomlake Verge, Undercity Sewers, Swamp, Cavern of Souls, and Multiversal Passage define spell availability more than raw land count. Preserve black access for Duress, Bitter Triumph, Day of Black Sun, Requiting Hex, Deadly Cover-Up, and Insatiable Avarice; preserve blue access for Stock Up, Winternight Stories, and blue sideboard interaction. Use Cavern of Souls for creature commitments when relevant, but do not keep or sequence as though it casts noncreature interaction unless Veles confirms it.

Card Hover Notes

Doomsday Excruciator

• Deck role: Main deck, 3 copies, primary black-heavy finisher and library-compression engine.
• Role type: threat/clock; engine payoff; reach/finisher.
• Deck-specific job: A 6/6 flying Demon that, when cast, leaves each player with only the bottom six library cards face down and then draws an extra card for you at each upkeep; this turns Dimir Excruciator's discard, removal, and sweepers into a short endgame.
• Timing: Cast after Duress, Strategic Betrayal, Bitter Triumph, Requiting Hex, Day of Black Sun, or Deadly Cover-Up has reduced the opponent's best punish; spend it earlier only when the 6/6 flyer is needed to end a race before their battlefield rebuilds.
• Inputs / outputs: Consumes {B}{B}{B}{B}{B}{B}; outputs a flying clock, a cast-only library exile trigger for both players, and recurring upkeep card draw.
• Partners / packages: Duress and Strategic Betrayal clear counters or sweepers; Cavern of Souls naming Demon can make the creature spell uncounterable; Day of Black Sun and Deadly Cover-Up create safe post-reset windows.
• Role peers: Superior Spider-Man and Restless Reef also close games; Emeritus of Ideation and Quantum Riddler provide blue flying pressure with card flow instead of library compression.
• Failure modes: The library exile trigger requires Doomsday Excruciator to be cast, so reanimation or copy-style entries should not be assumed to compress libraries; six black pips can be stranded by Cavern of Souls or blue-heavy mana.
• Matchup / visibility hooks: Best against slow decks after hand disruption; risky against fast creature starts, exile removal, or opponents who can win from the last six cards before your upkeep draw matters.

Restless Reef

• Deck role: Main deck, 4 copies, tapped Dimir mana resource and late-game creature threat.
• Role type: mana/fixing/ramp; threat/clock; mechanic enabler.
• Deck-specific job: Fixes {U}/{B} while becoming a 4/4 blue and black Shark with deathtouch that mills target player four on attack, giving the deck a post-sweeper win condition that does not spend a spell from hand.
• Timing: Play on turns where the tapped entry does not block Duress, Requiting Hex, Bitter Triumph, or Stock Up; animate only when the 4/4 deathtouch attack changes the clock and leaves enough mana for visible interaction or survival.
• Inputs / outputs: Enters tapped, taps for {U} or {B}, and consumes {2}{U}{B} to become a Shark until end of turn; an attack mills target player four cards.
• Mode map: Mana mode fixes blue or black; creature mode converts spare mana into a 4/4 deathtouch attacker/blocker; attack trigger can mill the opponent to pressure library resources or mill yourself only when Superior Spider-Man or Emeritus of Ideation needs exact graveyard material.
• Partners / packages: Day of Black Sun and Deadly Cover-Up clear blockers first; Superior Spider-Man can use milled creature cards; Emeritus of Ideation can spend cards in your graveyard for its attack trigger.
• Role peers: Watery Grave and Gloomlake Verge fix colors faster; Doomsday Excruciator, Superior Spider-Man, and Emeritus of Ideation are nonland finishers.
• Failure modes: Entering tapped costs tempo, and animating into open removal can trade away a mana source; milling an opponent with graveyard payoffs can help them.
• Matchup / visibility hooks: Strong in attrition mirrors and after sweepers; hold back versus aggro when the activation would remove blocker mana or expose a lethal counterattack.

Deceit

• Deck role: Main deck, 4 copies, flexible Elemental Incarnation interaction bridge and threat.
• Role type: modal utility; interaction-discard; interaction-removal; threat/clock.
• Deck-specific job: Uses color-spent triggers to either bounce up to one other target nonland permanent with {U}{U}, strip a nonland card from target opponent with {B}{B}, or do both when the mana supports it; evoke gives early access to the trigger package without keeping the 5/5.
• Timing: Evoke on turns where a bounce or discard trigger protects the next Stock Up, Superior Spider-Man, or Doomsday Excruciator line; hard-cast when a 5/5 body stabilizes combat and the mana can deliberately include the trigger colors you need.
• Inputs / outputs: Costs {4}{U/B}{U/B} or evoke {U/B}{U/B}; outputs a 5/5 unless evoked, plus blue-spent bounce and/or black-spent hand disruption.
• Mode map: Hard cast keeps the 5/5 and can trigger blue, black, or both color checks; evoke trades the body for a cheaper enter trigger; the blue trigger targets another nonland permanent, while the black trigger targets an opponent and you choose a nonland card from their revealed hand.
• Partners / packages: Duress and Oildeep Gearhulk reinforce hand pressure; Stock Up and Winternight Stories find the mana or payoff after Deceit opens the window; Cavern of Souls naming Elemental can support uncounterable hard casts but not noncreature spells.
• Role peers: Duress is cheaper hand disruption; Bitter Triumph and Requiting Hex answer creatures; Sunderflock is the other Elemental payoff but plays as a top-end bounce reset.
• Failure modes: Paying the wrong colors loses the intended trigger, and evoke gives up the body; Cavern of Souls mana only works for a creature spell of the chosen type.
• Matchup / visibility hooks: Blue trigger matters against hate permanents and blockers; black trigger matters before commitment turns against control, combo, and removal-heavy midrange.

Duress

• Deck role: Main deck, 3 copies plus sideboard 1 copy, proactive information and protection spell.
• Role type: interaction-discard; protection/evasion; sideboard bullet.
• Deck-specific job: Reveals target opponent's hand and lets you choose a noncreature, nonland card, clearing counters, sweepers, removal, graveyard hate, planeswalkers, or combo pieces before Dimir Excruciator taps low.
• Timing: Cast early against unknown or slow opponents to map their plan; save a copy when the next turn is Doomsday Excruciator, Superior Spider-Man, Emeritus of Ideation, Deadly Cover-Up, or Stock Up and the opponent may have a punishing noncreature answer.
• Inputs / outputs: Consumes {B} and one card for hand information plus one chosen legal discard from the opponent.
• Partners / packages: Protects Doomsday Excruciator, Superior Spider-Man, Emeritus of Ideation, Restless Reef activation turns, Stock Up reloads, and Deadly Cover-Up resets.
• Role peers: Strategic Betrayal attacks battlefield and graveyard resources instead of hand; Deceit's black-spent trigger and Oildeep Gearhulk can also inspect and pressure hands.
• Failure modes: Cannot take creature cards or mana resources, and topdecked answers can still punish the protected line.
• Matchup / visibility hooks: Highest value versus control, combo, sweepers, and removal-heavy midrange; trim only when creature battlefield pressure makes Requiting Hex, Bitter Triumph, Day of Black Sun, or Deadly Cover-Up more urgent.

Swamp

• Deck role: Main deck, 9 copies, core basic black mana resource.
• Role type: mana/fixing/ramp.
• Deck-specific job: Provides untapped {B} for Duress, Requiting Hex, Bitter Triumph, Insatiable Avarice, Day of Black Sun, Deadly Cover-Up, Strategic Betrayal, and the six-black Doomsday Excruciator endgame.
• Timing: Prioritize early when the hand contains one-mana discard/removal or when Gloomlake Verge needs an Island or Swamp condition; keep enough black sources visible before leaning on Cavern of Souls or Restless Reef activation lines.
• Inputs / outputs: Uses the land drop and taps for {B}; as a basic it is painless and keeps Multiversal Passage or shockland life decisions less costly.
• Partners / packages: Gloomlake Verge can make {B} once you control Swamp; Watery Grave and Undercity Sewers share the Swamp type while adding blue access.
• Role peers: Watery Grave and Undercity Sewers add blue; Gloomlake Verge adds conditional black; Cavern of Souls cannot cast noncreature black interaction with colored mana.
• Failure modes: Swamp-heavy hands can strand Stock Up, Winternight Stories, Emeritus of Ideation, Flashfreeze, Sunderflock, or Quantum Riddler.
• Matchup / visibility hooks: Best against fast decks where untapped black interaction matters immediately; against control, pair Swamp with blue sources before keeping card-flow hands.

Winternight Stories

• Deck role: Main deck, 2 copies, blue graveyard setup and reload spell.
• Role type: card selection; discard outlet; mechanic enabler.
• Deck-specific job: Draws three then discards two unless one discarded card is a creature, smoothing Dimir Excruciator while loading creature cards for Superior Spider-Man, Emeritus of Ideation, and later graveyard-resource decisions.
• Timing: Cast when the battlefield is stable enough to spend {2}{U}; preserve it when mana must stay open for Bitter Triumph, Requiting Hex, Flashfreeze, or Sunderflock. Harmonize from graveyard when tapping a creature and paying the reduced {4}{U} cost is stronger than attacking or blocking with that creature.
• Inputs / outputs: Normal cast consumes {2}{U}, draws three, then discards either two cards or one creature card; harmonize casts from graveyard for {4}{U}, may tap a creature to reduce by that creature's power, then exiles Winternight Stories.
• Mode map: Hand cast is the clean setup/reload mode; harmonize is a graveyard recast that spends a creature tap option and removes this spell from the graveyard after resolution.
• Partners / packages: Superior Spider-Man wants creature cards in graveyards; Emeritus of Ideation can exile eight cards from your graveyard on attack; Qarsi Revenant has Renew from graveyard after sideboarding.
• Role peers: Stock Up sees five and keeps two without discarding; Insatiable Avarice can tutor to top or draw three with life loss.
• Failure modes: Discarding the only stabilizer into visible graveyard hate or before Superior Spider-Man is ready can waste the setup.
• Matchup / visibility hooks: Strong in slower games and after one-for-one trades; too slow against fast starts unless removal already covers the board.

Bitter Triumph

• Deck role: Main deck, 3 copies, premium instant-speed creature and planeswalker answer.
• Role type: interaction-removal.
• Deck-specific job: Destroys target creature or planeswalker at instant speed, letting the deck preserve life, protect a sweeper plan, or clear a blocker for Superior Spider-Man, Doomsday Excruciator, Restless Reef, Emeritus of Ideation, or Oildeep Gearhulk.
• Timing: Hold until the target changes combat, threatens lethal, snowballs resources, or invalidates a planned Day of Black Sun or Deadly Cover-Up; cast earlier when waiting risks haste, protection, or a planeswalker activation.
• Inputs / outputs: Costs {1}{B} plus either discarding a card or paying 3 life; outputs destruction of one target creature or planeswalker.
• Partners / packages: Winternight Stories can make discard fodder; Duress can reveal whether paying life is safe; Requiting Hex handles mana value 2 or less so Bitter Triumph can be saved for larger threats.
• Role peers: Requiting Hex is cheaper but size-limited; Day of Black Sun and Deadly Cover-Up reset multiple creatures; The End is absent from this list.
• Failure modes: Paying 3 life can lose races, and discarding Doomsday Excruciator, Deadly Cover-Up, or the only blue card-flow spell may cost the long game.
• Matchup / visibility hooks: Excellent versus creature and planeswalker decks; lower priority against spell-heavy opponents with few battlefield targets.

Superior Spider-Man

• Deck role: Main deck, 4 copies, central graveyard-copy threat and stabilizer.
• Role type: threat/clock; mechanic payoff; graveyard enabler.
• Deck-specific job: Enters as a 4/4 Spider Human Hero and may copy any creature card in a graveyard while exiling that card, turning Winternight Stories, Restless Reef mills, trades, and opposing graveyard creatures into the best available battlefield body.
• Timing: Commit when a graveyard contains a worthwhile creature and Duress, Strategic Betrayal, Deceit, or Oildeep Gearhulk has reduced the risk; cast as a plain 4/4 when the deck needs a blocker or clock and copy value is not worth waiting.
• Inputs / outputs: Consumes {2}{U}{B}; may consume one creature card from any graveyard by exiling it as the copy choice; outputs a 4/4 with copied characteristics plus Superior Spider-Man's name and Spider Human Hero types.
• Mode map: Base entry is a 4/4; Mind Swap entry copies a chosen creature card in a graveyard and exiles that card, so pick the creature whose stats or enter ability matters most now.
• Partners / packages: Winternight Stories and Restless Reef can put creature cards into graveyards; Deceit, Doomsday Excruciator, Emeritus of Ideation, Qarsi Revenant, Oildeep Gearhulk, Quantum Riddler, and Sunderflock are high-impact copy candidates when present in graveyards.
• Role peers: Doomsday Excruciator is the black finisher; Restless Reef is the mana-source closer; Emeritus of Ideation is a blue flyer with graveyard fuel use.
• Failure modes: Graveyard hate can remove the intended card, and copying a legendary creature can create legend-rule problems if another same-name permanent is already yours.
• Matchup / visibility hooks: Best in creature mirrors, midrange attrition, and games where opposing graveyards contain premium bodies; weaker against exile-heavy or creature-light control.

Cavern of Souls

• Deck role: Main deck, 2 copies, creature-type fixing and anti-counter mana resource.
• Role type: mana/fixing/ramp; protection/evasion.
• Deck-specific job: Chooses a creature type, then makes {C} or one mana of any color only for creature spells of the chosen type while making that spell uncounterable.
• Timing: Choose the type for the threat you actually need to resolve: Demon for Doomsday Excruciator, Elemental for Deceit or Sunderflock, Human for Superior Spider-Man or Emeritus of Ideation, Construct for Oildeep Gearhulk, Vampire for Qarsi Revenant, or Sphinx for Quantum Riddler.
• Inputs / outputs: Uses a land drop; outputs {C} for any use or restricted colored mana for the chosen-type creature spell.
• Mode map: Colorless mana mode pays generic costs or activations; chosen-type colored mode casts a matching creature spell and adds counter protection, but cannot pay for Duress, Bitter Triumph, Requiting Hex, Stock Up, Day of Black Sun, or Flashfreeze.
• Partners / packages: Protects creature commitments after Duress or Strategic Betrayal; helps resolve Doomsday Excruciator through countermagic if Demon was chosen.
• Role peers: Watery Grave, Gloomlake Verge, Undercity Sewers, Swamp, Restless Reef, and Multiversal Passage provide spell mana without creature-type restriction.
• Failure modes: Wrong type selection strands colored creature mana, and opening hands with Cavern plus noncreature interaction can fail to cast early spells.
• Matchup / visibility hooks: Strong versus counterspell decks; weaker versus aggro where unrestricted black and blue mana matters more than counter protection.

Multiversal Passage

• Deck role: Main deck, 1 copy, flexible typed mana resource and life-payment fixer.
• Role type: mana/fixing/ramp; role glue.
• Deck-specific job: Chooses a basic land type as it enters and becomes that type, so in this Dimir deck it normally becomes Swamp for black interaction or Island for blue card flow and permission.
• Timing: Choose Swamp when Duress, Requiting Hex, Bitter Triumph, Day of Black Sun, Deadly Cover-Up, or Doomsday Excruciator is the bottleneck; choose Island when Stock Up, Winternight Stories, Flashfreeze, Sunderflock, Emeritus of Ideation, or Quantum Riddler is the bottleneck. Pay 2 life only if untapped mana changes the current turn.
• Inputs / outputs: Uses a land drop, chooses a basic type, may cost 2 life to enter untapped, and then functions with the mana ability of the chosen basic type.
• Mode map: Swamp choice supplies {B} and turns on Gloomlake Verge's black ability; Island choice supplies {U} and also turns on Gloomlake Verge; tapped choice preserves life, while paid untap preserves tempo.
• Partners / packages: Gloomlake Verge checks for Island or Swamp; Watery Grave and Undercity Sewers already provide both types but enter with different tempo costs.
• Role peers: Watery Grave is a shockland dual; Undercity Sewers surveils; Swamp is painless black; Restless Reef is tapped Dimir plus a late threat.
• Failure modes: Choosing the wrong type can lock a hand away from the needed color, and unnecessary 2-life payments make Bitter Triumph or Insatiable Avarice life costs harder to absorb.
• Matchup / visibility hooks: Choose untapped black versus fast starts; choose blue more often in slow games where Stock Up or permission decides the next turn cycle.

Day of Black Sun

• Deck role: Main deck, 3 copies, scalable black sorcery sweeper.
• Role type: interaction-sweeper.
• Deck-specific job: For chosen X, each creature with mana value X or less loses abilities until end of turn and is destroyed, giving Dimir Excruciator a way to reset early and midgame boards before landing a finisher.
• Timing: Cast before committing Superior Spider-Man, Doomsday Excruciator, Emeritus of Ideation, or Oildeep Gearhulk when the opponent has multiple relevant creatures; choose a smaller X when it prevents lethal now, and save for a higher X only when life total and blockers can absorb another attack.
• Inputs / outputs: Consumes {X}{B}{B} and a sorcery-speed turn; removes creatures by mana value threshold after stripping abilities for that turn.
• Partners / packages: Follow with Restless Reef activation, Superior Spider-Man, Doomsday Excruciator, Emeritus of Ideation, Quantum Riddler, or Oildeep Gearhulk after the battlefield clears.
• Role peers: Deadly Cover-Up is the five-mana total creature reset with optional extraction; Bitter Triumph and Requiting Hex are single-target answers.
• Failure modes: Sorcery timing cannot answer an attack already in progress, and your own Superior Spider-Man, Qarsi Revenant, Emeritus of Ideation, or Oildeep Gearhulk dies if its mana value is within X.
• Matchup / visibility hooks: Best against go-wide aggro and creature midrange; weaker versus planeswalkers, spell combo, and single expensive threats above the chosen X.

Undercity Sewers

• Deck role: Main deck, 2 copies, tapped Dimir typed mana resource with surveil setup.
• Role type: mana/fixing/ramp; card selection; mechanic enabler.
• Deck-specific job: Enters tapped as Island Swamp, taps for {U} or {B}, and surveils 1 to smooth draws or put a creature card into the graveyard for Superior Spider-Man and Emeritus of Ideation.
• Timing: Play when no immediate Duress, Requiting Hex, Bitter Triumph, or Flashfreeze window is being missed; value the surveil highly when deciding between land development, removal, and payoff setup.
• Inputs / outputs: Uses a land drop, enters tapped, produces {U} or {B}, and surveils 1 on entry by letting you keep the top card or put it into your graveyard.
• Partners / packages: Turns on Gloomlake Verge, fuels Superior Spider-Man and Emeritus of Ideation, and helps find Day of Black Sun, Stock Up, or a missing color.
• Role peers: Watery Grave can enter untapped for 2 life; Restless Reef is tapped but later becomes a Shark; Multiversal Passage can choose a needed basic type.
• Failure modes: Tapped entry can lose early interaction windows, and surveilling away a needed mana source can strand Doomsday Excruciator or Stock Up hands.
• Matchup / visibility hooks: Strong in slower games and graveyard-value setups; sequence cautiously versus fast aggro or prowess-style pressure.

Deadly Cover-Up

• Deck role: Main deck, 1 copy, singleton full sweeper and evidence-based extraction spell.
• Role type: interaction-sweeper; hate piece; modal utility.
• Deck-specific job: Destroys each creature, and with collect evidence 6 can exile a card from an opponent's graveyard plus cards with that name from their graveyard, hand, and library, turning a reset into targeted attrition.
• Timing: Cast when single-target interaction cannot stabilize; collect evidence only when your graveyard can spare six mana value and the named opposing card is worth removing from future draws.
• Inputs / outputs: Costs {3}{B}{B}; optional collect evidence 6 exiles cards from your graveyard as an additional cost; outputs a creature reset and, if evidence was collected, name-based extraction with replacement draws for hand cards exiled.
• Mode map: Base cast is a battlefield reset; evidence-enhanced cast adds graveyard/hand/library extraction keyed to a card from an opponent's graveyard.
• Partners / packages: Winternight Stories, Undercity Sewers, Restless Reef mill, and traded creatures can supply evidence; Duress reveals whether extracting a card name matters.
• Role peers: Day of Black Sun scales by mana value; Bitter Triumph and Requiting Hex answer one target; Strategic Betrayal exiles an opponent's graveyard without resetting the battlefield.
• Failure modes: Kills your creatures too, and collecting evidence can consume Superior Spider-Man copy targets or Emeritus of Ideation attack fuel.
• Matchup / visibility hooks: High value versus creature swarms, recursive threats, and decks built around multiple copies of one graveyard-visible threat; low value versus creature-light control.

Requiting Hex

• Deck role: Main deck, 4 copies, core cheap removal and optional life buffer.
• Role type: interaction-removal; lifegain/stabilization.
• Deck-specific job: Destroys target creature with mana value 2 or less, with blight 1 allowing a -1/-1 counter on your creature to gain 2 life when that life swing matters.
• Timing: Use early against low-mana threats that shorten the clock; pay blight when the -1/-1 counter on Superior Spider-Man, Deceit, Qarsi Revenant, Oildeep Gearhulk, or another creature will not compromise combat and 2 life changes the race.
• Inputs / outputs: Costs {B}; optional blight puts a -1/-1 counter on a creature you control as an additional cost; destroys one target creature with mana value 2 or less and gains 2 life if blight was paid.
• Mode map: Base cast is one-mana small-target removal; blight-enhanced cast adds self-counter cost for a life buffer.
• Partners / packages: Bitter Triumph handles larger creatures or planeswalkers; Day of Black Sun and Deadly Cover-Up cover wider boards; Nowhere to Run is not in this registered list.
• Role peers: Bitter Triumph is broader but costs a discard or 3 life; Day of Black Sun removes by mana value at sorcery speed.
• Failure modes: Cannot target mana value 3 or greater, and blight can shrink a blocker below survival math.
• Matchup / visibility hooks: Excellent versus aggro, token decks with low-cost key creatures, and burn races; weak against control or expensive threat decks.

Stock Up

• Deck role: Main deck, 3 copies, primary blue card-selection reload spell.
• Role type: card selection.
• Deck-specific job: Looks at the top five cards, puts two into your hand, and bottoms the rest, finding the next land, removal spell, sweeper, discard spell, or finisher without filling the graveyard.
• Timing: Cast when life total and battlefield allow a three-mana sorcery; choose immediate survival pieces over long-game power when the opponent has visible pressure.
• Inputs / outputs: Consumes {2}{U}; sees five cards, keeps two, and orders the remaining three on the bottom.
• Partners / packages: Finds Duress or Strategic Betrayal before commitment, Bitter Triumph or Requiting Hex for threats, Day of Black Sun or Deadly Cover-Up for resets, and Doomsday Excruciator or Superior Spider-Man to close.
• Role peers: Winternight Stories draws three and discards; Insatiable Avarice can tutor to top or draw three with life loss; Quantum Riddler draws on a body after sideboarding.
• Failure modes: Sorcery speed can be too slow under lethal pressure, and keeping two expensive cards instead of an answer can lose the next turn cycle.
• Matchup / visibility hooks: Strong in attrition and control games; against aggro, cast only after Requiting Hex, Bitter Triumph, or Day of Black Sun has handled immediate pressure.

Watery Grave

• Deck role: Main deck, 4 copies, primary Dimir shockland mana resource.
• Role type: mana/fixing/ramp.
• Deck-specific job: Provides Island and Swamp typing plus {U}/{B}, casting Duress, Requiting Hex, Bitter Triumph, Stock Up, Winternight Stories, Superior Spider-Man, Day of Black Sun, Deadly Cover-Up, and Doomsday Excruciator.
• Timing: Pay 2 life when untapped blue or black enables a real spell or response; let it enter tapped when no immediate action is required or life total is already under pressure.
• Inputs / outputs: Uses a land drop, may cost 2 life, enters untapped only if life is paid, and taps for {U} or {B}.
• Partners / packages: Turns on Gloomlake Verge, helps cast double-black sweepers and blue card flow, and supports Restless Reef activation turns.
• Role peers: Undercity Sewers always enters tapped but surveils; Swamp is painless black; Multiversal Passage can choose Island or Swamp; Restless Reef is tapped but can attack later.
• Failure modes: Repeated shock payments compound Bitter Triumph and Insatiable Avarice life costs.
• Matchup / visibility hooks: Untapped more often versus tempo/control windows; tapped more often against fast decks unless a one- or two-mana answer must be cast.

Strategic Betrayal

• Deck role: Main deck, 1 copy plus sideboard 1 copy, graveyard exile and battlefield disruption spell.
• Role type: interaction-removal; hate piece; sideboard bullet.
• Deck-specific job: Targets an opponent, then that opponent exiles a creature they control and their graveyard, combining an edict-style battlefield hit with graveyard denial.
• Timing: Cast when the opponent has one important creature or when their public graveyard is ready to fuel recursion, escape, flashback, or reanimation; delay against boards with expendable tokens unless graveyard exile is the main value.
• Inputs / outputs: Consumes {1}{B} at sorcery speed; target opponent chooses a creature they control to exile and exiles their graveyard.
• Partners / packages: Duress can show whether the graveyard piece is worth protecting against; Day of Black Sun and Deadly Cover-Up cover boards where the opponent can sacrifice a low-value creature to Strategic Betrayal.
• Role peers: Ghost Vacuum is repeatable precision graveyard hate; Deadly Cover-Up can extract same-name cards after evidence; Bitter Triumph and Requiting Hex choose their own target classes.
• Failure modes: The opponent controls the creature choice, so wide boards reduce the battlefield impact; sorcery speed cannot stop a graveyard spell already cast.
• Matchup / visibility hooks: Strong versus single-threat graveyard decks and recursive midrange; weak against token decks, empty graveyards, or creature-light control.

Gloomlake Verge

• Deck role: Main deck, 4 copies, blue-first conditional black mana resource.
• Role type: mana/fixing/ramp.
• Deck-specific job: Taps for {U} unconditionally and for {B} only if you control an Island or Swamp, supporting Stock Up and Winternight Stories while still casting black interaction after the condition is satisfied.
• Timing: Lead it when blue is needed and another source already supplies Island or Swamp; avoid keeping it as the only black source unless Watery Grave, Undercity Sewers, Swamp, or Multiversal Passage will enable {B} on time.
• Inputs / outputs: Uses a land drop; outputs {U}, or {B} with the Island/Swamp condition satisfied.
• Mode map: Blue ability is always available; black ability is conditional and should be planned around exact typed sources: Swamp, Watery Grave, Undercity Sewers, or Multiversal Passage choosing Island or Swamp.
• Partners / packages: Works with Watery Grave and Undercity Sewers for both colors; helps hold Flashfreeze or cast Stock Up while preserving future black interaction.
• Role peers: Watery Grave is unconditional with a life choice; Restless Reef is tapped Dimir; Swamp is reliable black only.
• Failure modes: Without Island or Swamp support, it cannot cast Duress, Requiting Hex, Bitter Triumph, Day of Black Sun, or Deadly Cover-Up.
• Matchup / visibility hooks: Strong in blue card-flow hands; risky versus aggro if black removal is not online immediately.

Emeritus of Ideation

• Deck role: Main deck, 1 copy, singleton blue flying value threat with Ancestral Recall aspect.
• Role type: modal utility; threat/clock; card selection; mechanic payoff.
• Deck-specific job: Front face is a 5/5 flying Human Wizard with ward {2}, prepared entry, and an attack trigger that may exile eight cards from your graveyard to become prepared; the Ancestral Recall face is a {U} instant that makes target player draw three cards.
• Timing: Cast Emeritus when a warded flyer stabilizes or ends the game; use Ancestral Recall when three cards now are worth spending the card as an instant, especially after removal has secured the battlefield or when digging for Day of Black Sun or Bitter Triumph.
• Inputs / outputs: Creature face consumes {3}{U}{U} and graveyard fuel for the attack trigger; instant face consumes {U} and targets a player to draw three.
• Mode map: Emeritus of Ideation face is the prepared flying threat; Ancestral Recall face is instant-speed card draw. Do not spend the instant face on the opponent unless forcing deck-out or a specific draw trigger is visibly correct.
• Partners / packages: Winternight Stories, Undercity Sewers, Restless Reef, and normal trades stock your graveyard; Duress and Strategic Betrayal protect the five-mana creature line.
• Role peers: Quantum Riddler is another blue flyer with draw text; Stock Up and Insatiable Avarice are noncreature card-flow options.
• Failure modes: The supplied reference provides face text but omits combined Oracle details, so follow runtime prompts for prepared handling; exiling eight cards can remove Superior Spider-Man copy targets.
• Matchup / visibility hooks: Strong against midrange and control after removal is traded; slower against aggro unless the 5/5 flyer immediately blocks or Ancestral Recall finds survival.

Insatiable Avarice

• Deck role: Main deck, 2 copies, black spree card-selection and draw spell.
• Role type: modal utility; tutor/search; card selection.
• Deck-specific job: Offers a top-deck tutor mode and a draw-three mode, letting Dimir Excruciator find a missing sweeper, land, discard spell, or finisher, or convert life into raw cards when stable.
• Timing: Use tutor mode when the next draw must be Day of Black Sun, Deadly Cover-Up, Doomsday Excruciator, Bitter Triumph, Requiting Hex, or a color source; use draw-three mode when life total is safe and multiple resources are better than one known card.
• Inputs / outputs: Base cost {B} plus spree additional costs; {2} mode searches library, shuffles, then puts the chosen card on top; {B}{B} mode makes target player draw three and lose 3 life.
• Mode map: Tutor mode fixes the next draw but does not put the card directly into hand; draw mode targets a player for three cards and 3 life loss; both modes can be chosen together when mana and life-total math justify it.
• Partners / packages: Finds Day of Black Sun or Deadly Cover-Up for wide boards, Duress for protection, Bitter Triumph or Requiting Hex for creatures, and Doomsday Excruciator or Superior Spider-Man for closure.
• Role peers: Stock Up immediately keeps two from five; Winternight Stories draws and discards; Emeritus of Ideation's Ancestral Recall face draws three without life loss if available.
• Failure modes: Sorcery timing and life loss are dangerous under pressure, and tutor mode is weak if the opponent can shuffle, mill, or force discard before your next draw.
• Matchup / visibility hooks: Strong in control mirrors and after stabilization; risky versus fast red decks or creature boards where 3 life matters.

Decorum Dissertation

• Deck role: Sideboard, 1 copy, black Lesson card-flow and recurring paradigm threat.
• Role type: sideboard bullet; card selection; engine piece.
• Deck-specific job: Makes target player draw two and lose 2 life, then paradigm exiles the spell and can copy it for free at the beginning of each of your first main phases after the first resolution.
• Timing: Bring in for slow matchups where repeated cards and life loss can outpace one-for-one exchanges; cast once the battlefield is stable enough that a five-mana sorcery will not concede tempo.
• Inputs / outputs: Consumes {3}{B}{B}; target player draws two and loses 2 life; paradigm turns the first resolution into future free copies from exile at first main phase.
• Mode map: Initial cast spends mana and establishes paradigm; later copied casts are upkeep-like first-main-phase card flow and life pressure without spending a card from hand.
• Partners / packages: Duress and Strategic Betrayal clear counters or opposing haymakers; Deadly Cover-Up and Day of Black Sun stabilize before the recurring draw engine takes over.
• Role peers: Insatiable Avarice draws three with life loss; Stock Up finds two cards immediately; Quantum Riddler and Oildeep Gearhulk are sideboard threats with card advantage attached.
• Failure modes: Targeting yourself costs life, and targeting the opponent gives them cards unless the life loss or deck-out plan is decisive.
• Matchup / visibility hooks: Best versus grindy control and midrange; avoid versus aggro unless your life total and battlefield are secure.

Qarsi Revenant

• Deck role: Sideboard, 2 copies, lifelink flying deathtouch threat and graveyard Renew source.
• Role type: sideboard bullet; threat/clock; lifegain/stabilization; recursion.
• Deck-specific job: A 3/3 flying, deathtouch, lifelink Vampire that can later Renew from graveyard for {2}{B} by exiling itself to put flying, deathtouch, and lifelink counters on target creature at sorcery speed.
• Timing: Bring in when life swing and evasive blocking matter; cast as a creature to stabilize races, or save Renew for Superior Spider-Man, Doomsday Excruciator, Oildeep Gearhulk, or Restless Reef when granting all three counters changes combat.
• Inputs / outputs: Creature costs {1}{B}{B}; Renew consumes {2}{B}, exiles Qarsi Revenant from graveyard, targets a creature, and adds flying, deathtouch, and lifelink counters at sorcery speed.
• Mode map: Creature mode is a stabilizing 3/3; Renew mode is graveyard-based counter transfer and cannot be used at instant speed.
• Partners / packages: Winternight Stories can discard it when Renew is the plan; Superior Spider-Man can copy it from graveyard before Qarsi Revenant is exiled for Renew.
• Role peers: Oildeep Gearhulk is the larger lifelink stabilizer; Quantum Riddler is a blue flyer without lifelink.
• Failure modes: Renew removes Qarsi Revenant from the graveyard and can be stopped by graveyard hate; sorcery timing cannot ambush attackers.
• Matchup / visibility hooks: Strong versus aggro, flyers, and races; weaker against exile removal or control decks that ignore combat life swings.

Ghost Vacuum

• Deck role: Sideboard, 1 copy, artifact graveyard hate and delayed creature-conversion engine.
• Role type: hate piece; sideboard bullet; engine piece.
• Deck-specific job: Taps to exile target card from a graveyard, then can later pay {6}, tap, and sacrifice itself at sorcery speed to put each creature card exiled with it onto the battlefield under your control as a 1/1 Spirit with a flying counter.
• Timing: Deploy or activate before the opponent can use a public graveyard card; save the sacrifice activation until it returns at least one relevant creature or creates lethal flying damage.
• Inputs / outputs: Costs {1}; tap ability exiles one target graveyard card; second ability consumes {6}, tap, and Ghost Vacuum to create Spirit creatures from the creature cards it exiled.
• Mode map: Hate mode is repeatable single-card exile; payoff mode cashes in the stored creature cards and sacrifices the artifact at sorcery speed.
• Partners / packages: Strategic Betrayal and Deadly Cover-Up also attack graveyards; Restless Reef can mill creature cards that Ghost Vacuum may then exile.
• Role peers: Strategic Betrayal is one-shot opponent graveyard exile; Deadly Cover-Up extracts a named card after evidence.
• Failure modes: Exiling a card after flashback, escape, or similar costs are paid usually will not stop the already-cast spell; noncreature cards exiled with Ghost Vacuum do not become Spirits.
• Matchup / visibility hooks: Bring against reanimation, flashback, escape, recursive creatures, and graveyard-count engines; leave out when the opponent's graveyard is incidental.

Oildeep Gearhulk

• Deck role: Sideboard, 3 copies, lifelink stabilizer and hand-pressure threat.
• Role type: sideboard bullet; lifegain/stabilization; interaction-discard; threat/clock.
• Deck-specific job: A 4/4 artifact Construct with lifelink and ward {1} that looks at target player's hand on entry, may choose a card, makes that player discard it, then draw a card.
• Timing: Bring in where a lifelink body and hand disruption matter; cast after Duress or removal has made the battlefield safe, or before a finisher turn to cycle away the opponent's best known card.
• Inputs / outputs: Consumes {U}{U}{B}{B}; outputs a 4/4 lifelink ward body plus a hand-look trigger that can trade the opponent's best card for a random draw.
• Partners / packages: Duress gives prior hand information; Day of Black Sun and Deadly Cover-Up clear boards before Oildeep Gearhulk stabilizes; Superior Spider-Man can copy it from a graveyard.
• Role peers: Qarsi Revenant is the cheaper lifelink flyer; Deceit's black-spent trigger discards without giving a replacement draw; Quantum Riddler is card advantage rather than discard.
• Failure modes: The discard trigger gives the target player a replacement draw, so do not choose a low-impact card if the random draw is likely better for them.
• Matchup / visibility hooks: Strong versus aggro races and midrange hands with one key card; weaker versus empty-handed opponents or decks that punish four-mana artifacts.

Quantum Riddler

• Deck role: Sideboard, 2 copies, blue flying card-advantage threat.
• Role type: sideboard bullet; threat/clock; card selection; modal utility.
• Deck-specific job: A 4/6 flyer that draws a card on entry and increases future draw events by one while you have one or fewer cards in hand; Warp {1}{U} gives an alternate early access mode.
• Timing: Bring in for attrition and slower matchups; hard-cast when a 4/6 flyer stabilizes or pressures, and use Warp only when the runtime action shows the temporary access line is better than saving the card for a full body.
• Inputs / outputs: Hard cast costs {3}{U}{U} for a 4/6 flyer and one card; Warp costs {1}{U} and follows the runtime's alternate-zone handling.
• Mode map: Full cast is a threat that draws a card; Warp is an alternate access mode that should be chosen only when the short-term card draw or tempo matters more than a normal five-mana creature.
• Partners / packages: Stock Up, Winternight Stories, Insatiable Avarice, Decorum Dissertation, and Emeritus of Ideation's Ancestral Recall face become stronger when the extra-draw replacement is active at one or fewer cards in hand.
• Role peers: Emeritus of Ideation is another five-mana flyer; Oildeep Gearhulk stabilizes with lifelink; Stock Up is cheaper selection.
• Failure modes: Warp details depend on runtime rules output, and the extra-draw text turns on only at one or fewer cards in hand.
• Matchup / visibility hooks: Strong versus control and midrange attrition; slow versus fast decks unless the 4/6 body immediately blocks profitably.

Flashfreeze

• Deck role: Sideboard, 2 copies, color-specific stack interaction.
• Role type: interaction-stack; sideboard bullet.
• Deck-specific job: Counters target spell on the stack if that spell is red or green, giving Dimir Excruciator a cheap answer to qualifying threats, sweepers, damage spells, ramp payoffs, and planeswalkers before resolution.
• Timing: Hold {1}{U} when the opponent has shown qualifying colors and their next spell can change the race; spend it on a medium target only if waiting risks losing the ability to protect Superior Spider-Man, Doomsday Excruciator, or Day of Black Sun.
• Inputs / outputs: Consumes {1}{U} and one card; counters one target red-or-green spell on the stack.
• Partners / packages: Protects Doomsday Excruciator, Superior Spider-Man, Restless Reef attacks, Emeritus of Ideation, Oildeep Gearhulk, and Quantum Riddler from qualifying stack threats.
• Role peers: Sunderflock is a creature reset rather than a counterspell; Duress can remove noncreature answers before they are cast.
• Failure modes: Cannot answer a resolved permanent and cannot counter a spell that is not red or green.
• Matchup / visibility hooks: Bring versus red aggro, Gruul-style midrange, green ramp, and red removal decks; leave out versus Dimir mirrors or creature-light decks without qualifying stack objects.

Sunderflock

• Deck role: Sideboard, 2 copies, expensive Elemental flyer and creature-reset finisher.
• Role type: sideboard bullet; threat/clock; interaction-removal; modal utility.
• Deck-specific job: A 5/5 flying Elemental that costs {X} less where X is the greatest mana value among Elementals you control and, when cast, returns each non-Elemental creature to its owner's hand on entry.
• Timing: Bring in when bouncing opposing creature boards is stronger than killing them, especially after Deceit is present as an Elemental to reduce cost; cast only when returning your own non-Elemental creatures is acceptable or when the 5/5 flyer ends the game.
• Inputs / outputs: Base cost is {7}{U}{U}; Deceit can reduce the cost because it is an Elemental Incarnation; output is a flying body and a cast-only mass bounce of non-Elemental creatures.
• Mode map: Full-cost mode is a nine-mana finisher; reduced-cost mode uses Deceit's mana value as the current Elemental discount. The enter trigger is a reset, not a counterspell.
• Partners / packages: Deceit is the key current-list Elemental for cost reduction; Cavern of Souls naming Elemental can help cast Deceit or Sunderflock through counters.
• Role peers: Day of Black Sun and Deadly Cover-Up are black sweepers; Deceit can bounce one nonland permanent; Quantum Riddler is a cheaper flyer.
• Failure modes: The trigger returns your Superior Spider-Man, Doomsday Excruciator, Qarsi Revenant, Oildeep Gearhulk, Quantum Riddler, and Emeritus of Ideation too because they are not Elementals.
• Matchup / visibility hooks: Strong versus creature boards that rebuild slowly; poor versus spell combo, control, or decks with enter triggers that benefit from being replayed.

Interaction Priorities

• Priority: Use Duress and Strategic Betrayal to clear the card that beats the next committed line, not the flashiest card in hand. Take sweepers, hard removal, counterplay, combo payoffs, or planeswalkers before generic card draw when preparing Doomsday Excruciator, Superior Spider-Man, Emeritus of Ideation, Oildeep Gearhulk, or a Restless Reef activation.

• Priority: Kill engines before attackers when the life total is above immediate danger. Point Bitter Triumph, verified Requiting Hex, verified Day of Black Sun, or Deadly Cover-Up at permanents that produce repeat cards, mana, tokens, graveyard value, or unavoidable damage; a single ordinary attacker can wait if the next turn contains a sweeper or blocker.

• Priority: Kill attackers before engines when the visible clock is short. At 8 life or lower, or when the next combat plus known burn-style pressure could be lethal, use Bitter Triumph or any verified removal mode on the creature that most reduces incoming damage, even if a slower engine remains.

• Counter or bounce first only when legal action text confirms that role. Flashfreeze and Sunderflock are sideboard interaction, but card text check required for exact targets and effects; use them on spells or permanents that would invalidate the current control plan, force through lethal pressure, or punish a tapped-out finisher turn.

• Exile first when graveyard recursion, escape-style value, reanimation, or death triggers are visibly central. Ghost Vacuum is the sideboard graveyard tool, but card text check required; use it on public graveyard cards that the opponent can legally reuse or convert into pressure before spending premium removal on replaceable battlefield material.

• Ignore low-impact creatures when a sweeper is likely to gain value. Do not spend Bitter Triumph on a small attacker that can be absorbed by life total, blocked by Superior Spider-Man, or caught by Day of Black Sun or Deadly Cover-Up, unless it carries equipment, counters, evasion, or an on-board lethal clock.

• Bait with lower-commitment spells before exposing top-end. Cast Deceit, Stock Up, Winternight Stories, Insatiable Avarice, or a redundant interaction spell into open mana before Doomsday Excruciator or Emeritus of Ideation when the hand has time; against control, use Duress first if available.

• Archetype shift: Against aggro, value tempo and life preservation over perfect card advantage. Trade removal for early damage sources, accept imperfect Day of Black Sun timing if waiting risks lethal, and avoid life-payment modes from Bitter Triumph or Insatiable Avarice unless the alternative loses.

• Archetype shift: Against control and combo, protect the commitment turn. Save Duress and Strategic Betrayal for the turn before the decisive threat or answer, hold Bitter Triumph for must-answer permanents, and prefer Stock Up when the battlefield is quiet and the opponent is not presenting an immediate kill.

Combat And Trading Rules

• Attack only when the exchange advances a control finish. Use Doomsday Excruciator, Superior Spider-Man, Emeritus of Ideation, Oildeep Gearhulk, Qarsi Revenant, Quantum Riddler, or animated Restless Reef as pressure after the opponent is low on cards, the board is stabilized, or the attack preserves enough mana and blockers for the next turn cycle.

• Preserve engine and finisher bodies unless the trade prevents a loss. Do not trade Doomsday Excruciator, Emeritus of Ideation, or a sideboard top-end creature for a medium attacker if removal, a sweeper, or a chump block can cover the turn; do trade them when the visible board otherwise produces lethal or a game-ending snowball.

• Block early against aggro with the goal of buying sweeper time. Favor blocks that keep life above 8 and set up Day of Black Sun, Deadly Cover-Up, or a stabilizing Oildeep Gearhulk; decline blocks that expose the only future win condition when the attack is not materially changing the clock.

• Trade down when the hand contains card advantage and enough mana. If Stock Up, Winternight Stories, Insatiable Avarice, or verified value from Emeritus of Ideation can reload, exchange creatures and removal for time; this deck wins many games by surviving into repeated answer-plus-threat turns.

• Avoid animating Restless Reef into open removal unless the attack is necessary. Treat Restless Reef as a land first and a finisher second; activate it when sweepers have cleared blockers, the opponent is constrained by Duress, or the damage materially shortens the clock without sacrificing needed interaction mana.

• Protect life total more tightly when using life-payment spells. If Bitter Triumph or Insatiable Avarice has already cost life or offers a life-payment choice, prefer blocks and removal that prevent chip damage; the deck should not convert cards into a position where every topdecked opposing threat is lethal.

• Pressure control before they rebuild, but do not overextend into known sweepers. One resilient threat plus Restless Reef is often enough; keep extra creatures in hand if Duress revealed mass removal or if the opponent has passed with suspicious mana and no pressure.

• Against graveyard or recursion decks, trade only with a graveyard plan. If the opponent benefits from creatures dying, prioritize exile or containment through verified Ghost Vacuum lines and Deadly Cover-Up decisions; otherwise, use combat to force resources into the graveyard only when the follow-up answer is ready.

Selection And Tutor Rules

• Selection: Treat Stock Up, Winternight Stories, Insatiable Avarice, and Deceit as pseudo-selection unless Veles exposes exact tutor or search text. This deck has no confirmed unconditional tutor in the registered main deck; do not plan as though any card can find a named card from library without a legal search prompt.

• Land timing: Delay the land drop until after a legal draw/filter spell when current mana already casts that spell and the hand lacks a clear land choice. Make the land drop first when the spell requires the extra mana, when holding up Bitter Triumph matters, or when a tapped-land choice would otherwise waste the turn.

• Selection rank: Take missing mana before power when the hand cannot cast interaction on curve. Prioritize black sources for Duress, Bitter Triumph, Day of Black Sun, Requiting Hex, Deadly Cover-Up, and Insatiable Avarice; prioritize blue sources when the next turns depend on Stock Up, Winternight Stories, sideboard Flashfreeze, or sideboard Sunderflock.

• Selection rank: Take survival cards over finishers when the opponent has a visible clock. Prefer Bitter Triumph, Day of Black Sun, Requiting Hex, Deadly Cover-Up, or a castable blocker over Doomsday Excruciator, Emeritus of Ideation, or extra card draw when the next combat threatens a large life swing.

• Selection rank: Take pressure and hand disruption over removal when the battlefield is empty and the opponent is resource-rich. Prefer Duress, Strategic Betrayal, Doomsday Excruciator, Superior Spider-Man, or Emeritus of Ideation when the opponent’s likely path is hand sculpting, counterplay, or a single must-answer spell.

• Bottom or decline low-impact cards when Veles exposes scry, surveil, or keep/bottom choices. Bottom excess tapped lands after the fourth or fifth land if hand already casts Doomsday Excruciator; bottom redundant expensive threats before stabilizing; keep cheap interaction when the opponent can punish a slow turn.

• Preserve named-answer flexibility when choosing from multiple visible cards. Do not lock into Deadly Cover-Up or Day of Black Sun if a single Bitter Triumph answers the only relevant permanent and selection can instead find lands, discard, or a win condition.

• Sideboard selection: Use Ghost Vacuum only when the opponent’s public graveyard or visible strategy makes graveyard interaction relevant. Card text check required for Ghost Vacuum; choose graveyard targets only from legal public candidates and prioritize cards the opponent can reuse or convert into immediate pressure.

Priority And Stack Rules

• Priority: Pass on empty-stack priority when no legal action improves the current turn cycle. Do not cast Bitter Triumph, Duress, Strategic Betrayal, Stock Up, Insatiable Avarice, or a finisher merely because mana is available; use the action only when timing advances discard, survival, selection, or threat commitment.

• Response window: Use Bitter Triumph at instant speed when a creature or planeswalker will generate value before the next main phase, attack for lethal, enable a combo, or invalidate a sweeper plan. If the threat can be caught by Day of Black Sun or Deadly Cover-Up without losing the game, let it resolve and save the instant.

• Response window: Let low-impact spells resolve when the answer is needed for a decisive permanent or stack threat. Preserve sideboard Flashfreeze and Sunderflock for legal targets that change the game state materially; card text check required for exact allowed targets and effects.

• Discard timing: Cast Duress or Strategic Betrayal before committing Doomsday Excruciator, Emeritus of Ideation, Oildeep Gearhulk, or an animated Restless Reef attack when the opponent has cards and mana. Do not fire discard into an empty or known-irrelevant hand unless Veles shows a legal tactical reason.

• Draw timing: Cast Stock Up, Winternight Stories, Insatiable Avarice, or Deceit on the opponent’s end step only if legal action text confirms instant-speed timing. If the spell is sorcery-speed or timing is unclear, use it in main phase after deciding whether the land drop should be held for selection information.

• Combat window: Hold instant interaction through declare attackers when the opponent could animate, pump, or commit an attacker. Use removal before blockers only when it changes blocks or prevents lethal; use it after blockers only when the legal action preserves a blocker, punishes a trick, or removes a creature before damage.

• Optional payment: Decline life-payment or extra-cost choices from Bitter Triumph, Insatiable Avarice, or any verified optional mode when life is the limiting resource. Accept the cost when the alternative is losing the key answer, missing the next land/interaction piece, or failing to stop a visible lethal line.

• Graveyard timing: Use Ghost Vacuum, Deadly Cover-Up, or other graveyard-affecting legal actions before the opponent can reuse public graveyard cards. Do not spend graveyard interaction on generic cards if the stack or battlefield contains the immediate threat.

• Activation timing: Treat Restless Reef as a land until attacking is safe or necessary. Activate only when Veles shows legal activation, mana remains for needed interaction, and the opponent’s open mana or known hand does not make the land-creature exchange unacceptable.

Sideboard Map

• Strategic Betrayal: Add this against slower decks, hand-heavy decks, control mirrors, combo-like graveyard decks, and opponents whose best cards must be taken before Doomsday Excruciator, Emeritus of Ideation, or Oildeep Gearhulk resolves. Card text check required; treat it as hand disruption or strategic selection only when Veles exposes legal action text confirming the effect. It is weak against empty-hand aggro, board-only creature pressure, and games where life total or battlefield stabilization matters more than hand information.

• Decorum Dissertation: Add this when its legal text supports card advantage, selection, or a high-impact control exchange in slow matchups. Card text check required; do not assume it removes creatures, counters spells, or wins attrition without a visible legal effect. It is weak when the opponent is forcing immediate combat survival, when tapping mana in main phase exposes you to lethal, or when the hand already contains multiple Stock Up, Winternight Stories, or Insatiable Avarice effects and lacks removal.

• Qarsi Revenant: Add this against creature decks where a body, recursion pressure, lifegain, or graveyard-adjacent value is confirmed by legal text. Card text check required; evaluate it as a stabilizer only from visible power/toughness, cost, abilities, and current battlefield. It is weak against exile-heavy control, opponents with few creatures to trade with, and matchups where graveyard exposure makes Deadly Cover-Up or opponent graveyard interaction more punishing.

• Ghost Vacuum: Add this against graveyard, recursion, reanimation, flashback-style, or death-trigger-heavy opponents. Card text check required; use it only on legal public graveyard objects and prioritize cards the opponent can reuse or cards whose presence enables a visible engine. It is weak against decks with no graveyard reliance, fast battlefield pressure, and control mirrors where a non-threat, non-answer artifact leaves the deck too reactive.

• Oildeep Gearhulk: Add this as the heavy top-end plan against midrange, control, and removal-light creature decks where reaching the late game is realistic. Card text check required; do not assume a specific enters-the-battlefield trigger, removal mode, or recursion mode unless Veles exposes it. It is weak against fast aggro when the deck needs cheaper answers, against counter-heavy opponents if discard has not cleared the way, and in hands already crowded with Doomsday Excruciator plus Emeritus of Ideation.

• Duress: Add the fourth Duress against control, combo-like decks, spell-dense midrange, sweepers, planeswalker-heavy strategies if visible, and any opponent where resolving Doomsday Excruciator requires clearing a path. It is weak against creature-saturated aggro, low-hand topdeck games, and boards where the immediate problem is an attacking permanent already in play.

• Quantum Riddler: Add this against slow decks, board stalls, and matchups where a resilient threat or card-quality engine is better than more one-for-one removal. Card text check required; evaluate it by visible cost, stats, keywords, and legal trigger text. It is weak against fast starts when it does not block immediately, against decks that punish tapping out, and in post-board plans already adding several expensive cards.

• Flashfreeze: Add this only when Veles or matchup metadata confirms legal targets are likely and impactful. Card text check required; do not assume exact color restrictions or spell types until action text is visible. It is weak against black, blue, artifact-heavy, colorless, or creature-board strategies where legal targets are sparse; when in doubt, preserve more flexible cards like Bitter Triumph, Day of Black Sun, Requiting Hex, or Stock Up.

• Sunderflock: Add this when its legal text interacts profitably with the opponent’s key permanent, spell, graveyard line, or combat plan. Card text check required; treat it as flexible interaction only after seeing the action family Veles offers. It is weak when the opponent presents threats outside its confirmed range, when mana efficiency is critical, or when the deck needs proactive discard rather than reactive answers.

Control Or Spell-Dense Midrange Side in: 1 Strategic Betrayal; 1 Decorum Dissertation; 1 Duress; 2 Quantum Riddler; 2 Oildeep Gearhulk Cut: 3 Day of Black Sun; 1 Deadly Cover-Up; 2 Requiting Hex; 1 Bitter Triumph

• Plan: Increase discard, resilient threats, and slow-card quality while reducing dead battlefield-only interaction. Keep some Bitter Triumph and Requiting Hex because control decks can still win with a single permanent or creature-land; do not overload on expensive sideboard threats if the opening hand cannot interact before turn three.

Fast Creature Aggro Side in: 2 Qarsi Revenant; 2 Sunderflock; 1 Ghost Vacuum Cut: 1 Strategic Betrayal; 1 Emeritus of Ideation; 2 Insatiable Avarice; 1 Stock Up

• Plan: Add bodies, flexible interaction, and graveyard containment if the opponent uses recursive pressure. Preserve Day of Black Sun, Bitter Triumph, Requiting Hex, and Deadly Cover-Up as the core survival package. Reduce main-deck emphasis on life-payment draw, slow finishers, and hand disruption that does not answer permanents already attacking.

Graveyard Or Recursion Side in: 1 Ghost Vacuum; 1 Duress; 1 Strategic Betrayal; 2 Sunderflock Cut: 2 Winternight Stories; 1 Emeritus of Ideation; 1 Stock Up; 1 Requiting Hex

• Plan: Add graveyard pressure, hand information, and flexible answers while keeping enough removal for creatures that escape graveyard containment. Do not fire Ghost Vacuum at the first legal target if a more important public graveyard card is likely to appear before the opponent’s next reuse window. Reduce main-deck emphasis on slower selection when the opponent’s graveyard engine must be interrupted immediately.

Big Mana Or Expensive Threats Side in: 1 Duress; 1 Strategic Betrayal; 2 Flashfreeze; 2 Oildeep Gearhulk Cut: 3 Day of Black Sun; 1 Deadly Cover-Up; 1 Requiting Hex; 1 Bitter Triumph

• Plan: Add proactive hand disruption, conditional permission, and heavier finishers. Keep cheaper interaction when the opponent also presents early creatures; otherwise prioritize stopping the payoff spell before it resolves. Use Duress and Strategic Betrayal before tapping out for Doomsday Excruciator or Oildeep Gearhulk.

Mirror Or Black-Blue Attrition Side in: 1 Strategic Betrayal; 1 Decorum Dissertation; 1 Duress; 2 Quantum Riddler; 3 Oildeep Gearhulk Cut: 3 Day of Black Sun; 1 Deadly Cover-Up; 2 Requiting Hex; 2 Bitter Triumph

• Plan: Become threat-dense and information-heavy while accepting that some removal remains necessary for Restless Reef, Superior Spider-Man, Doomsday Excruciator, Emeritus of Ideation, Quantum Riddler, or Oildeep Gearhulk. Do not keep a removal-light hand only because the sideboard plan is threat-heavy; the mirror can still pivot to battlefield pressure.

• Archetype rule: Add role cards only when they solve the matchup’s actual axis. Against fast boards, add Qarsi Revenant, Sunderflock, and sometimes Ghost Vacuum; against slow hands, add Duress, Strategic Betrayal, Decorum Dissertation, Quantum Riddler, and Oildeep Gearhulk; against graveyard decks, add Ghost Vacuum first and support it with discard or flexible interaction.

• Role-change rule: Doomsday Excruciator shifts from primary closer to one of several must-answer threats after adding Oildeep Gearhulk or Quantum Riddler. Duress and Strategic Betrayal shift from early disruption to protection for expensive threats when the opponent has open mana and cards in hand.

• Bad-plan rule: Do not add every expensive sideboard card just because the matchup is slow. Keep the curve functional, keep enough black interaction for creature-lands or resolved threats, and avoid hands where Oildeep Gearhulk, Doomsday Excruciator, Emeritus of Ideation, and Quantum Riddler compete for the same late-game turn.

Matchup Guidance

• Aggro: Treat the first four turns as a survival test, not a card-advantage contest. Keep hands with black mana, early interaction, and a clear path to cast Bitter Triumph, Requiting Hex, or Day of Black Sun; ship slow hands built around Stock Up, Winternight Stories, Insatiable Avarice, Emeritus of Ideation, or multiple top-end threats without removal. Add role cards: Qarsi Revenant, Sunderflock, and sometimes Ghost Vacuum if the pressure recurs from the graveyard. Reduce main-deck emphasis: life-payment draw, slow selection, and discard that cannot answer creatures already on board.

• Control: Make the opponent spend answers on staggered must-answer threats while Duress and Strategic Betrayal clear the way for the important turn. Do not run Doomsday Excruciator, Oildeep Gearhulk, Quantum Riddler, or Emeritus of Ideation into open interaction when a discard action is legal and the opponent still has cards in hand. Add role cards: Duress, Strategic Betrayal, Decorum Dissertation, Quantum Riddler, and Oildeep Gearhulk. Reduce main-deck emphasis: Day of Black Sun, Deadly Cover-Up, and excess creature-only removal unless public battlefield pressure requires it.

• Combo: Use discard before card draw when the opponent’s hand is the likely resource that matters. Prioritize Duress and Strategic Betrayal against visible setup spells, payoff cards, protection, or card-selection engines; preserve Bitter Triumph, Requiting Hex, and Sunderflock only when Veles shows they can hit the relevant permanent, creature, or stack object. Add role cards: Duress, Strategic Betrayal, Flashfreeze when legal target expectations are confirmed, and Sunderflock when its visible action text covers the combo axis. Reduce main-deck emphasis: sweepers that do not break up the combo and expensive threats that do not shorten the clock.

• Tempo: Force the opponent to answer on your terms by trading early, making land drops, and casting threats when you can still pay for visible taxes or recover from a bounce/removal exchange. Stock Up is strong only after stabilizing mana and board position; do not spend turn three selecting cards if a legal Bitter Triumph, Requiting Hex, or Day of Black Sun prevents a large attack. Add role cards: Duress, Qarsi Revenant, Sunderflock, and sometimes Quantum Riddler if it blocks or resists interaction. Reduce main-deck emphasis: clunky late game, conditional sweepers against few threats, and draw spells under a short clock.

• Midrange: Trade resources until your top-end outclasses theirs, then protect the first threat that changes the battlefield or hand economy. Superior Spider-Man, Doomsday Excruciator, Emeritus of Ideation, Restless Reef, Oildeep Gearhulk, and Quantum Riddler are all potential pressure sources, but card text check required before assuming evasion, recursion, or triggered value. Add role cards: Strategic Betrayal, Decorum Dissertation, Quantum Riddler, and Oildeep Gearhulk when games slow down. Reduce main-deck emphasis: narrow removal only if the opponent trims creatures; keep enough answers for resolved threats.

• Big mana: Stop the payoff turn rather than spending premium removal on low-impact setup unless the setup visibly enables lethal or an immediate lock. Duress and Strategic Betrayal should be used before tapping out, and Flashfreeze belongs only when matchup metadata or legal actions indicate it can counter important spells. Add role cards: Duress, Strategic Betrayal, Flashfreeze, and Oildeep Gearhulk. Reduce main-deck emphasis: Day of Black Sun, Deadly Cover-Up, and small removal when the opponent wins through single expensive spells rather than multiple creatures.

• Graveyard: Identify whether the graveyard is a value source, a combo resource, or a recursive combat plan before spending hate. Ghost Vacuum should be held for the first public graveyard card that is about to matter, not fired at a harmless card when the opponent has not reached a reuse window. Add role cards: Ghost Vacuum, Duress, Strategic Betrayal, and Sunderflock. Reduce main-deck emphasis: slow selection and threat-only hands that let the graveyard engine operate uncontested. Keep Bitter Triumph, Requiting Hex, and Day of Black Sun when graveyard decks still win by attacking.

• Artifact/enchantment: Do not assume Dimir Excruciator can answer noncreature permanents unless Veles exposes a legal action that says so. Use Duress and Strategic Betrayal to take engines before they resolve, use Sunderflock only when its legal text confirms coverage, and pressure with Doomsday Excruciator, Superior Spider-Man, Restless Reef, or sideboard threats before the permanent engine buries you. Add role cards: Sunderflock, Duress, Strategic Betrayal, Quantum Riddler, and Oildeep Gearhulk. Reduce main-deck emphasis: sweepers or removal that miss the permanent type.

• Go-wide: Preserve sweepers and avoid one-for-one trades that leave the next attack lethal. Day of Black Sun and Deadly Cover-Up are the core reset tools; hold them when life total permits and the opponent is likely to commit more creatures, but cast them immediately when the visible board represents a short clock. Add role cards: Qarsi Revenant and Sunderflock; add Ghost Vacuum only if recursion is visible or expected. Reduce main-deck emphasis: Duress, Stock Up, Winternight Stories, and Insatiable Avarice when they cost too much tempo.

• Single-threat: Save the cleanest answer for the threat that actually wins the game. Bitter Triumph, Requiting Hex, Sunderflock, and sometimes Flashfreeze should be aimed at the large creature, protected threat, or stack object Veles marks as legal and relevant; do not spend them on small enablers unless those enablers are the only path to the threat. Add role cards: Flashfreeze when confirmed, Sunderflock, Duress, and Strategic Betrayal. Reduce main-deck emphasis: broad sweepers unless the single-threat deck also makes backup bodies.

• Burn: Treat life total as a scarce resource and avoid optional life payments unless they directly prevent more damage than they cost. Keep cheap interaction and blockers, use Duress to take high-impact noncreature burn when legal, and avoid Insatiable Avarice lines that expose a shorter clock. Add role cards: Duress, Qarsi Revenant, and Sunderflock if it interacts with a burn spell or creature. Reduce main-deck emphasis: slow draw, expensive finishers, and painful lines from Watery Grave when an untapped shock land is not required.

• Removal-heavy decks: Win by sequencing threat density, creature-lands, and discard rather than by protecting a single creature at all costs. Use Duress and Strategic Betrayal to clear sweepers or premium removal before committing Doomsday Excruciator, Oildeep Gearhulk, Quantum Riddler, or Emeritus of Ideation; use Restless Reef to pressure after both players trade resources. Add role cards: Decorum Dissertation, Quantum Riddler, Oildeep Gearhulk, Strategic Betrayal, and Duress. Reduce main-deck emphasis: Day of Black Sun and excess removal if the opponent presents few creatures.

• Unknown opponent: Keep a balanced Game 1 hand with mana, one early interaction spell, one source of card flow or pressure, and no more than one speculative slow card. Lead with Duress when legal against an unknown hand if it can reveal the opponent’s plan and take a noncreature threat or answer; otherwise prioritize land development and removal availability. Sideboard after seeing the real axis, not the deck name alone.

Specific Matchup Notes

• General/archetype-only note: Exact opponent decklists are absent, so revealed cards, legal actions, and public board state override these assumptions. Use these notes to bias discard, removal, draw timing, and sideboard-role selection only after Veles confirms the opponent’s actual axis.

• Aggro and go-wide: Stabilize first, then win with any surviving closer or Restless Reef. Priority targets are the creature or pump effect that makes the next attack lethal, followed by engines that rebuild after Day of Black Sun or Deadly Cover-Up. Add role cards: Qarsi Revenant, Sunderflock, and sometimes Duress when the opponent shows important noncreature damage or protection. Reduce main-deck emphasis: slow Stock Up, Winternight Stories, Insatiable Avarice, and expensive threats when life total is already under pressure.

• Tempo and flash interaction: Make land drops and force the opponent to spend mana before committing a closer. Priority targets are bounce/removal that answers Doomsday Excruciator, Superior Spider-Man, Emeritus of Ideation, or animated Restless Reef; use Duress and Strategic Betrayal before tapping low. Add role cards: Duress, Sunderflock, Qarsi Revenant, and Quantum Riddler if its visible text helps contest combat or card flow. Reduce main-deck emphasis: sweepers against low creature counts and draw spells that skip an interaction window.

• Midrange mirrors: Trade one-for-one until your late cards or creature-land pressure matter more than theirs. Priority targets are planeswalker-like engines, recursive threats, and removal that lines up cleanly against your top-end; do not fire Bitter Triumph or Requiting Hex into a low-value target if a larger threat is likely from public sequencing. Add role cards: Strategic Betrayal, Decorum Dissertation, Quantum Riddler, and Oildeep Gearhulk; card text check required before assuming the exact value mode for these sideboard threats.

• Control and removal-heavy decks: Protect threat density by sequencing discard before expensive commitments. Priority targets are sweepers, hard answers to Doomsday Excruciator, and card-advantage engines; pressure with Restless Reef after removal exchanges when the legal action is safe against visible mana. Add role cards: Duress, Strategic Betrayal, Decorum Dissertation, Quantum Riddler, and Oildeep Gearhulk. Reduce main-deck emphasis: Day of Black Sun, Deadly Cover-Up, and excess creature removal when the opponent shows few creatures.

• Graveyard and recursion decks: Hold graveyard hate until a public card is about to be reused or a visible legal action confirms graveyard dependency. Priority targets are the graveyard card enabling the current turn, the spell that rebuys it, or the creature that converts graveyard size into lethal pressure. Add role cards: Ghost Vacuum, Duress, Strategic Betrayal, and Sunderflock; keep Bitter Triumph, Requiting Hex, and Day of Black Sun when the opponent still wins through combat.

• Big mana and single-payoff decks: Fight the payoff turn rather than spending premium interaction on harmless setup. Priority targets are the first spell or permanent that actually dominates the board, invalidates removal, or creates immediate lethal pressure. Add role cards: Duress, Strategic Betrayal, Flashfreeze when color and legal action text confirm coverage, and Oildeep Gearhulk. Reduce main-deck emphasis: small removal and sweepers when the opponent’s threat count is low.

Risk Summary

• Mana risk: Cavern of Souls, Multiversal Passage, Restless Reef, Undercity Sewers, Gloomlake Verge, Watery Grave, Deceit, and Swamp must be sequenced for real legal costs, not assumed perfect fixing. Avoid hands that cannot cast early black interaction, and do not take painful Watery Grave lines unless the untapped mana changes a visible decision.

• Matchup risk: Dimir Excruciator can draw the wrong half when the opponent’s axis is unknown. Use Duress and early public information to classify the matchup before spending Day of Black Sun, Deadly Cover-Up, Bitter Triumph, or Requiting Hex on low-impact objects.

• Draw-risk: Stock Up, Winternight Stories, and Insatiable Avarice can lose tempo when the board already threatens a short clock. Cast card-flow spells only when life total, blockers, and available interaction make the skipped turn defensible.

• Over-sideboarding risk: Adding too many speculative sideboard cards can dilute the deck’s core of discard, removal, card flow, and closers. Keep enough main-deck pressure from Doomsday Excruciator, Superior Spider-Man, Emeritus of Ideation, and Restless Reef to finish games after stabilizing.

• Graveyard risk: Ghost Vacuum is narrow if the opponent does not expose a graveyard resource. Do not spend it or mulligan toward it unless matchup metadata, revealed cards, or legal actions show graveyard relevance.

• Sweeper/removal risk: Day of Black Sun and Deadly Cover-Up may be stranded against low-creature decks, while Bitter Triumph and Requiting Hex may be overloaded against wide boards. Preserve the answer type that matches the visible threat pattern instead of maximizing mana efficiency alone.

• Closer risk: Doomsday Excruciator, Superior Spider-Man, Emeritus of Ideation, Oildeep Gearhulk, and Quantum Riddler require card text checks before assuming evasion, inevitability, or protection. Treat them as commitments that need discard cover or a stable board unless Veles exposes deterministic winning text.

• Interaction risk: Duress, Strategic Betrayal, Flashfreeze, and Sunderflock are only as good as the legal targets Veles shows. Never hold up narrow interaction over casting a stabilizer when the opponent’s current visible board can win before the narrow card matters.

• Sequencing risk: Animated Restless Reef, tapped-land timing, discard-before-threat turns, and draw-before-land decisions can change legal options. Prefer sequences that keep removal or counterplay available through the opponent’s next turn when the board is not yet secure.

Test Feedback Checklist

• Deciding factor: Record whether the game turned on early discard, stabilizing removal, card-flow velocity, a closer surviving, Restless Reef pressure, sideboard cards, or a missed interaction window. Tie the answer to public events, not inferred hidden cards.

• Mulligans: Ask whether each keep could cast early black interaction from Swamp, Watery Grave, Gloomlake Verge, Undercity Sewers, Deceit, Restless Reef, Cavern of Souls, or Multiversal Passage. Flag hands with Stock Up, Winternight Stories, or Insatiable Avarice that lacked time to use them.

• Mana: Check whether tapped lands, painful Watery Grave, Cavern of Souls naming, or color sequencing changed the available legal action. Note every turn where Bitter Triumph, Duress, Requiting Hex, Day of Black Sun, or Deadly Cover-Up was delayed by mana.

• Velocity: Identify whether Stock Up, Winternight Stories, and Insatiable Avarice converted spare mana into relevant cards or stranded the pilot under pressure. Record whether drawing cards before land play improved the turn or created missed sequencing.

• Engines and closers: Track when Doomsday Excruciator, Superior Spider-Man, Emeritus of Ideation, animated Restless Reef, Oildeep Gearhulk, or Quantum Riddler actually ended the game or demanded removal. Card text check required before crediting any specific engine text.

• Removal: Review whether Bitter Triumph, Requiting Hex, Day of Black Sun, Deadly Cover-Up, Sunderflock, or Flashfreeze answered the threat that mattered most. Mark low-impact removal if a later visible threat immediately invalidated the exchange.

• Sideboard: Compare the sideboard plan to the opponent’s revealed axis after the match. Ask whether Duress, Strategic Betrayal, Decorum Dissertation, Qarsi Revenant, Ghost Vacuum, Oildeep Gearhulk, Quantum Riddler, Flashfreeze, or Sunderflock had legal targets and timely impact.

• Closing: Record whether the deck stabilized but failed to finish before the opponent recovered. Note whether Restless Reef attacks, Doomsday Excruciator, Superior Spider-Man, or Emeritus of Ideation were held too long after the opponent was low on visible resources.

• Role: Ask whether the pilot correctly became control, midrange pressure, or emergency stabilizer after public information appeared. Flag games where the pilot spent mana on draw while the board required removal, or spent removal while a discard-first turn was safer.

• Mistakes: List legal-action mistakes separately from strategic disagreements. Examples include passing with relevant interaction, animating Restless Reef into visible punishment, firing Duress after committing a closer, or choosing draw over survival.

• Stranded cards: Count how often Day of Black Sun, Deadly Cover-Up, Duress, Strategic Betrayal, Flashfreeze, Ghost Vacuum, and expensive threats sat unused. Separate mana-stranding from matchup-stranding.

• Overperformers and underperformers: Name cards that repeatedly changed winning probability from visible outcomes. Do not upgrade or downgrade Decorum Dissertation, Qarsi Revenant, Oildeep Gearhulk, Quantum Riddler, or Sunderflock without card text confirmation and match evidence.

First Tuning Questions

• Quantity: Does Doomsday Excruciator need the third copy, or did hands with multiple expensive closers lose to tempo before stabilization? Compare against games where one copy was decisive.

• Quantity: Are two Winternight Stories and three Stock Up enough velocity, or did the deck run out of relevant actions after trading Duress, Bitter Triumph, and Requiting Hex?

• Quantity: Is Insatiable Avarice a necessary bridge to late-game resources, or did its life or tempo cost matter in aggressive matchups? Card text check required for exact risk.

• Mana: Are four Restless Reef and the tapped-land mix costing too many early interaction turns? Review games where turn-one or turn-two Duress, Bitter Triumph, or Requiting Hex was unavailable.

• Mana: Are two Cavern of Souls and one Multiversal Passage improving threat deployment enough to justify awkward nonblack or conditional mana spots?

• Aggro plan: Does the main deck need more early stabilizers if Day of Black Sun and Deadly Cover-Up arrive too late? Use damage taken before the first sweeper as the metric.

• Control plan: Does the sideboard contain enough discard and must-answer pressure for removal-heavy opponents, or are Doomsday Excruciator, Superior Spider-Man, and Restless Reef being answered one at a time?

• Closers: Is Emeritus of Ideation a meaningful singleton closer, or is it too hard to find when games require a final threat? Card text check required before changing its role.

• Sideboard slots: Is Ghost Vacuum narrow but game-winning against graveyard decks, or does it sit dead too often? Keep it only if public graveyard interactions justify the slot.

• Sideboard slots: Do Flashfreeze and Sunderflock cover enough visible opposing actions to earn four total slots, or should those slots become broader interaction?

• Role conflict: Are Stock Up, Winternight Stories, Insatiable Avarice, and expensive threats competing for the same safe windows? If yes, reduce the cards that underperform when the deck must answer immediately.

• Sideboard threat plan: Do Oildeep Gearhulk and Quantum Riddler improve closing speed or overload removal after sideboarding? Card text check required, then judge by games where they were cast with discard or interaction support.

Veles Tactical Policy

Policy: Keep Functional Interaction Hands

Priority: Medium Decision families: mulligan Cards: Duress; Bitter Triumph; Requiting Hex; Day of Black Sun; Stock Up; Winternight Stories; Insatiable Avarice Phase windows: pregame, opening hand, mulligan decisions Runtime cues: prompt:mulligan, visible opening hand, known play/draw status Use when: the opener has black mana, at least two lands, and either early interaction or a believable draw-to-stabilize curve. Avoid when: the hand cannot cast black interaction before the opponent develops pressure, has only tapped or conditional mana, or contains only expensive/card-flow spells. Instructions: Prefer hands that trade early with Duress, Bitter Triumph, or Requiting Hex; keep slow Stock Up, Winternight Stories, or Insatiable Avarice hands only when lands and interaction already function. Card text check required for exact draw-risk and life-risk calculations. Pilot skill floor: light-model No-API allowed: no Light-model allowed: yes

Policy: Build Black Mana Before Blue Velocity

Priority: Medium Decision families: mana Cards: Swamp; Watery Grave; Gloomlake Verge; Undercity Sewers; Deceit; Restless Reef; Cavern of Souls; Multiversal Passage Phase windows: turns 1-4, land play, precombat main phase Runtime cues: action:play land, visible hand costs, legal interaction actions Use when: multiple land plays are legal and the hand contains black interaction, sweepers, or discard. Avoid when: a blue source is the only way to cast an immediate legal Stock Up, Winternight Stories, or sideboard spell that must be used this turn. Instructions: Sequence for early black first, then blue card flow. Treat Restless Reef, Undercity Sewers, Deceit, Cavern of Souls, and Multiversal Passage as context-sensitive until Forge exposes exact mana and tapped status. Pilot skill floor: light-model No-API allowed: no Light-model allowed: yes

Policy: Cavern Naming Gate

Priority: Low Decision families: mana Cards: Cavern of Souls; Doomsday Excruciator; Superior Spider-Man; Emeritus of Ideation; Oildeep Gearhulk; Quantum Riddler; Qarsi Revenant Phase windows: land entry, mana setup, threat deployment turns Runtime cues: action:choose type, action:choose name, visible hand creature names Use when: Cavern of Souls asks for a choice and the hand contains a specific threat that needs uncounterable or colored support. Avoid when: the hand has no creature or artifact-creature payoff visible, or the needed threat type cannot be confirmed from card text. Instructions: Choose the type that supports the most important visible threat only after checking legal text. Card text check required for all non-obvious card types, especially Superior Spider-Man, Doomsday Excruciator, Oildeep Gearhulk, Quantum Riddler, and Qarsi Revenant. Pilot skill floor: light-model No-API allowed: no Light-model allowed: yes

Policy: Early Discard Before Commitment

Priority: Medium Decision families: interaction, priority Cards: Duress; Strategic Betrayal Phase windows: early main phases, pre-threat turns, post-sideboard control mirrors Runtime cues: action:cast Duress, action:cast Strategic Betrayal, opponent hand reveal windows Use when: discard is legal before committing Doomsday Excruciator, Superior Spider-Man, Emeritus of Ideation, or a post-board threat. Avoid when: the board requires immediate removal or sweeper action to survive the next visible attack. Instructions: Use discard to clear interaction, learn public-safe hand information, and decide whether to tap out. Card text check required for Strategic Betrayal; do not assume it functions like Duress unless Forge exposes matching legal actions. Pilot skill floor: light-model No-API allowed: no Light-model allowed: yes

Policy: Deterministic Duress Opponent Target

Priority: Low Decision families: interaction, selection Cards: Duress Phase windows: Duress target prompt Runtime cues: action:target opponent Duress Use when: the only legal target action contains target opponent and Duress. Avoid when: more than one target action is visible, the legal action text does not name Duress, or the prompt includes card-selection after the target. Instructions: Select the opponent target and return control to normal decision logic for any revealed-card choice. Pilot skill floor: no-api No-API allowed: yes Light-model allowed: yes

Policy: Removal Target Gate

Priority: High Decision families: interaction, priority Cards: Bitter Triumph; Requiting Hex; Day of Black Sun; Deadly Cover-Up; Sunderflock Phase windows: opponent combat, end step, own main phase, stack response windows Runtime cues: action:cast Bitter Triumph, action:cast Requiting Hex, action:cast Day of Black Sun, action:cast Deadly Cover-Up, action:cast Sunderflock Use when: a legal removal or sweeper action can answer visible lethal pressure, a must-answer engine, or a threat that invalidates the current plan. Avoid when: the target is low impact, a sweeper is better against multiple visible creatures, or the spell text/target legality is not confirmed. Instructions: Spend spot removal on threats that change the race or stop stabilization; prefer sweepers when multiple opposing creatures make one-for-one removal insufficient. Card text check required for Requiting Hex, Day of Black Sun, Deadly Cover-Up, and Sunderflock. Pilot skill floor: light-model No-API allowed: no Light-model allowed: yes

Policy: Survival Sweeper Commitment

Priority: High Decision families: interaction, priority Cards: Day of Black Sun; Deadly Cover-Up Phase windows: own main phase before combat, opponent end step only if legal Runtime cues: action:cast Day of Black Sun, action:cast Deadly Cover-Up, visible battlefield creature count Use when: visible opposing attackers threaten lethal or force losing blocks before the next turn. Avoid when: the board is stable, your own visible threat is the primary win condition, or Forge text shows the sweeper will not answer the relevant permanents. Instructions: Cast the sweeper before card-flow or threat deployment when survival is at risk. Card text check required for exact destruction, exile, toughness, and graveyard clauses. Pilot skill floor: light-model No-API allowed: no Light-model allowed: yes

Policy: Card Flow Safety Window

Priority: Medium Decision families: priority, selection Cards: Stock Up; Winternight Stories; Insatiable Avarice; Decorum Dissertation Phase windows: own main phase, opponent end step if legal, post-stabilization turns Runtime cues: action:cast Stock Up, action:cast Winternight Stories, action:cast Insatiable Avarice, action:cast Decorum Dissertation Use when: life total, board, and mana allow spending a turn or window on cards instead of removal. Avoid when: visible pressure demands Bitter Triumph, Requiting Hex, Day of Black Sun, Deadly Cover-Up, or blockers. Instructions: Use draw and selection to find land, interaction, or closers after stabilizing; do not spend scarce mana on velocity when the next combat step is dangerous. Card text check required for exact draw, selection, and life-payment modes. Pilot skill floor: light-model No-API allowed: no Light-model allowed: yes

Policy: Threat Commitment Gate

Priority: High Decision families: priority, mana Cards: Doomsday Excruciator; Superior Spider-Man; Emeritus of Ideation; Oildeep Gearhulk; Quantum Riddler; Qarsi Revenant Phase windows: own main phase, post-discard windows, post-sweeper windows Runtime cues: action:cast Doomsday Excruciator, action:cast Superior Spider-Man, action:cast Emeritus of Ideation, action:cast Oildeep Gearhulk, action:cast Quantum Riddler, action:cast Qarsi Revenant Use when: the board is stable enough to commit a closer or the opponent’s visible/known resources make waiting worse. Avoid when: open interaction is known from a reveal, lethal pressure requires removal, or holding mana preserves a better response. Instructions: Deploy closers after discard or after forcing the opponent to spend resources. Card text check required before assigning exact finisher, recursion, or enters-the-battlefield value roles. Pilot skill floor: light-model No-API allowed: no Light-model allowed: yes

Policy: Restless Reef Conversion

Priority: Medium Decision families: combat, mana Cards: Restless Reef Phase windows: late main phase, combat, opponent end step if activation is legal Runtime cues: action:activate Restless Reef, action:attack with Restless Reef Use when: activating or attacking advances a clock while leaving enough mana for required interaction. Avoid when: visible removal, profitable blocks, or mana needs make the land more important as a source than as a creature. Instructions: Treat Restless Reef as a finisher after stabilization, not an early tempo gamble. Card text check required for exact activation cost, stats, and attack/trigger text. Pilot skill floor: light-model No-API allowed: no Light-model allowed: yes

Policy: Attack Only From Stabilized Boards

Priority: Medium Decision families: combat Cards: Superior Spider-Man; Doomsday Excruciator; Emeritus of Ideation; Oildeep Gearhulk; Quantum Riddler; Qarsi Revenant; Restless Reef Phase windows: declare attackers, post-sweeper pressure turns Runtime cues: prompt:declare attackers, visible blockers, legal attack actions Use when: attacks preserve a defensive plan or materially shorten the opponent’s clock. Avoid when: attacking exposes the only stabilizer, walks into visible blocks, or removes mana needed for interaction through Restless Reef. Instructions: Prefer attacks that maintain control of the next combat step; hold creatures back when racing math is unclear and the opponent has visible pressure. Pilot skill floor: light-model No-API allowed: no Light-model allowed: yes

Policy: Block For Survival First

Priority: High Decision families: combat Cards: Superior Spider-Man; Doomsday Excruciator; Emeritus of Ideation; Oildeep Gearhulk; Quantum Riddler; Qarsi Revenant; Restless Reef Phase windows: declare blockers, combat damage prevention windows Runtime cues: prompt:declare blockers, visible lethal attack, legal block actions Use when: blocking prevents lethal, preserves a high life buffer, or trades a replaceable threat for a visible attacker that matters. Avoid when: the block sacrifices the only win condition and life total remains safe through the next turn. Instructions: Make survival blocks over damage-race blocks; use removal before blocks when it produces a cleaner combat step. Card text check required for exact keywords, toughness, and combat abilities. Pilot skill floor: light-model No-API allowed: no Light-model allowed: yes

Policy: Permission And Stack Interaction Gate

Priority: High Decision families: interaction, priority Cards: Flashfreeze; Sunderflock; Bitter Triumph; Requiting Hex Phase windows: opponent spell on stack, combat trick windows, end step Runtime cues: action:cast Flashfreeze, action:cast Sunderflock, visible stack item Use when: a legal stack interaction can stop a threat, engine, lethal action, or card type that the spell can legally affect. Avoid when: the stack object is low impact, spell text does not match the target, or later visible board pressure demands removal mana. Instructions: Use Flashfreeze and Sunderflock only on stack objects Forge marks legal; do not infer color, type, or counterability beyond visible engine output. Card text check required for exact modes and restrictions. Pilot skill floor: light-model No-API allowed: no Light-model allowed: yes

Policy: Graveyard-Hate Timing

Priority: Medium Decision families: interaction, priority Cards: Ghost Vacuum Phase windows: opponent graveyard setup, response windows, sideboard games Runtime cues: action:cast Ghost Vacuum, action:activate Ghost Vacuum, visible graveyard contents Use when: the opponent’s public graveyard is part of their visible plan or Forge exposes a legal graveyard-hate activation. Avoid when: the graveyard is irrelevant and the board requires removal, discard, or a threat. Instructions: Deploy or activate Ghost Vacuum for public graveyard leverage, not as a low-impact mana sink under pressure. Card text check required for exact exile, timing, and artifact text. Pilot skill floor: light-model No-API allowed: no Light-model allowed: yes

Policy: Sideboard Plan Selection

Priority: High Decision families: sideboard Cards: Strategic Betrayal; Decorum Dissertation; Qarsi Revenant; Ghost Vacuum; Oildeep Gearhulk; Duress; Quantum Riddler; Flashfreeze; Sunderflock Phase windows: between games, after revealed matchup information Runtime cues: prompt:sideboard, match stage, opponent revealed cards, sideboard legal plans Use when: choosing a validated plan after Game 1 or Game 2. Avoid when: the proposed plan violates the registered 75 or cuts more main-deck copies than available. Instructions: Add discard and resilient threats against slow decks, add Flashfreeze or Sunderflock only where legal targets are expected from public information, add Ghost Vacuum only against graveyard dependence, and keep enough main-deck removal for creature pressure. Card text check required for all sideboard-role refinements. Pilot skill floor: light-model No-API allowed: no Light-model allowed: yes

Policy: Sideboard Lock Confirmation

Priority: Low Decision families: sideboard Cards: Strategic Betrayal; Decorum Dissertation; Qarsi Revenant; Ghost Vacuum; Oildeep Gearhulk; Duress; Quantum Riddler; Flashfreeze; Sunderflock Phase windows: sideboard submission validation Runtime cues: action:submit sideboard plan Use when: the selected sideboard plan is already validated by Veles and the legal action text is exactly the submit action for that plan. Avoid when: Veles reports validation errors, unknown card counts, or multiple submit actions with different plans. Instructions: Submit only the already selected legal plan; do not alter card counts during no-API execution. Pilot skill floor: no-api No-API allowed: yes Light-model allowed: yes
