Strategy Specifications

Deck Name And Archetype

Dimir Control is a 60-card Alchemy control deck with no sideboard and a verified registered-zone split of 60 main / 0 sideboard. The active validation contract says the deck passes Alchemy deck-size rules: at least 60 main-deck cards and at most 15 sideboard cards. Runtime pilots must treat the empty sideboard as binding; there are no legal Side in: cards, no post-board transformation plans, and no ability to patch a matchup by adding external staples.

• Identity: The strategy name is Dimir Control, using blue-black mana from Island, Swamp, Drowned Catacomb, Watery Grave, Temple of Deceit, Gloomlake Verge, Fountainport, Soulstone Sanctuary, and Maelstrom of the Spirit Dragon.
• Format: The declared format is Alchemy, so digital-only card behavior may matter; Card text check required for Alchemy-specific or unfamiliar cards before relying on exact timing, perpetual, conjure, seek, or specialize-style assumptions.
• Tags: Current archetype/mechanic tags are control, control; treat the duplicate tag as confirmation that the default role is reactive control rather than tempo, combo, or creature-curve aggro.
• Stock status: This is best classified as a rogue or custom Dimir control shell, not a stock metagame list, because the registered configuration uses deck-specific packages such as Firdoch Core, Caustic Exhale, Dispelling Exhale, Draconic Fealty, Unholy Annex // Ritual Chamber, and Ugin, Eye of the Storms rather than a conventional copied archetype map.
• Role status: The deck appears built to answer opposing development, trade resources, and win after stabilizing with higher-impact permanents or threats; do not pilot it as a low-resource beatdown deck unless legal actions and visible board state make attacking clearly necessary.
• Mana concern: The mana base is heavily Dimir with several nonbasic lands and only 9 basic lands; prioritize legal land sequencing that preserves early black and blue availability for Caustic Exhale, Dispelling Exhale, Nowhere to Run, Nameless Inversion, Strategic Betrayal, and Villainous Wrath while still enabling later threats.
• Curve concern: The list includes multiple expensive or engine-like cards, including Scavenger Regent, Marang River Regent, Unholy Annex // Ritual Chamber, and Ugin, Eye of the Storms; mulligans and early turns should value hands that interact before those cards become relevant.
• Removal density: The main deck registers 4 Caustic Exhale, 4 Dispelling Exhale, 1 Nameless Inversion, 3 Villainous Wrath, and 2 Nowhere to Run, so the pilot should expect to answer creatures or permanents through legal interaction rather than racing every board.
• Threat density: The named creature and finisher package includes Scavenger Regent, Spirited Simulacrum, Cunning Azurescale, Marang River Regent, Firdoch Core, Draconic Fealty, Unholy Annex // Ritual Chamber, Ugin, Eye of the Storms, Fountainport, Soulstone Sanctuary, and Maelstrom of the Spirit Dragon; exact roles require card text verification when the rules engine does not expose enough visible text.
• Legality concern: The provided validation result passes, but the pilot must still obey runtime legal actions because Alchemy legality, rebalanced card text, and double-faced card handling for Unholy Annex // Ritual Chamber are engine responsibilities.
• Opponent information status: No opponent decklist, matchup label, play/draw policy, metagame target, or sideboard map was supplied, so pregame decisions should use visible public information, the current hand, and broad control principles without naming absent opponent cards in policy Cards: fields.
• Hidden-information rule: The guide cannot assume an opponent has specific threats, protection, discard, counters, sweepers, or haste cards unless revealed by public zones, logged known information, or rules-engine output.
• Runtime priority: Legal actions come first, visible board state second, and this deck-specific strategy third; when a legal action label contradicts a card-role assumption, follow the engine output and record the uncertainty for tuning.

Thesis

Dimir Control assembles stable Dimir mana, early answer density, and a small set of durable advantage or finisher permanents, then wins after the opponent is low on meaningful threats. The deck should prioritize survival, clean mana, and resource exchange before trying to close the game with Scavenger Regent, Spirited Simulacrum, Cunning Azurescale, Marang River Regent, Firdoch Core, Draconic Fealty, Unholy Annex // Ritual Chamber, Ugin, Eye of the Storms, Fountainport, Soulstone Sanctuary, or Maelstrom of the Spirit Dragon. Card text check required for the exact Alchemy behavior of the unfamiliar cards before relying on any specific trigger, activation, transformation, or combat stat line.

• Primary plan: Trade one-for-one or better with Caustic Exhale, Dispelling Exhale, Nameless Inversion, Strategic Betrayal, Villainous Wrath, and Nowhere to Run until an engine or threat can safely matter.
• Win pattern: Stabilize first, then convert repeated value, large bodies, creature-lands, token production, planeswalker-style pressure, or Dragon-related payoffs into inevitability if those modes are exposed by legal actions.
• Tempo rule: Do not spend early turns on low-impact development if the visible board is already threatening life total, hand size, or mana stability.
• Commitment rule: Do not tap out for Scavenger Regent, Marang River Regent, Unholy Annex // Ritual Chamber, Draconic Fealty, or Ugin, Eye of the Storms when the opponent has a visible lethal or near-lethal counterattack unless that spell is itself the legal stabilizing line.
• Non-plan: This deck is not trying to curve out as aggro, race from turn one, rely on hidden combo certainty, or preserve every threat forever; it is allowed to win slowly after the board is under control.
• Runtime priority: Follow legal actions and visible rules-engine information over all role assumptions, especially for Alchemy-only names whose text may not match paper-card intuition.

Role Package

• Threats: Scavenger Regent, Spirited Simulacrum, Cunning Azurescale, Marang River Regent, Firdoch Core, Draconic Fealty, Ugin, Eye of the Storms, Fountainport, Soulstone Sanctuary, and Maelstrom of the Spirit Dragon are the registered cards most likely to convert stabilization into a win. Card text check required for exact body size, activation timing, summoning-sickness relevance, and whether any land or permanent can attack, make tokens, transform, or generate damage.

• Payoffs: Draconic Fealty, Marang River Regent, Scavenger Regent, Maelstrom of the Spirit Dragon, and Ugin, Eye of the Storms look like the highest-ceiling late-game package from names and registration, but the pilot must treat their exact payoff modes as conditional on visible legal text. Commit these cards when the opponent's current board is contained, when hand resources need to become pressure, or when waiting risks losing the chance to deploy a finisher.

• Engines: Unholy Annex // Ritual Chamber, Ugin, Eye of the Storms, Fountainport, Soulstone Sanctuary, and possibly Firdoch Core are the cards most likely to create repeatable value or alternate pressure. Card text check required before treating any of them as draw, token production, mana conversion, transformation, recursion, or activated-threat engines.

• Velocity: Spirited Simulacrum, Cunning Azurescale, Strategic Betrayal, Unholy Annex // Ritual Chamber, Temple of Deceit, and any legal selection mode from Ugin, Eye of the Storms should be used to smooth hands only after immediate survival is addressed. If the engine shows a choice between more cards and answering a visible threat, choose the answer unless the visible clock is slow.

• Interaction: Caustic Exhale, Dispelling Exhale, Nameless Inversion, Villainous Wrath, Nowhere to Run, and Strategic Betrayal form the tactical control core. Preserve flexible answers for the opponent's highest-impact visible permanent, stack object, or attack step when the engine exposes that flexibility; spend narrow answers earlier if holding them risks wasting mana or taking avoidable damage.

• Protection: This list has no obvious dedicated protection suite from the registered names, so protect threats through timing, removal before combat, and not exposing a key permanent into visible open interaction when waiting is affordable. If Dispelling Exhale or another card exposes a protective legal mode, use it according to the current stack and board, not by assumption.

• Recursion: No registered card should be assumed to recur cards from graveyard without text confirmation. If Scavenger Regent, Unholy Annex // Ritual Chamber, Fountainport, Soulstone Sanctuary, or Maelstrom of the Spirit Dragon exposes recursion-like legal actions, prioritize returning or reusing the card that stabilizes the current visible problem rather than the largest abstract threat.

• Mana: Island, Swamp, Drowned Catacomb, Watery Grave, Temple of Deceit, Gloomlake Verge, Fountainport, Soulstone Sanctuary, and Maelstrom of the Spirit Dragon must support early blue-black interaction and later expensive threats. Sequence lands to keep both colors available, avoid unnecessary tapped-land delays when removal is needed, and treat utility-land activations as secondary to casting live answers.

• Sideboard modules: The registered sideboard is empty, so there are no legal sideboard role cards and no post-board package to add. Every matchup must be played with the same 60-card configuration; any improvement must come from mulligans, sequencing, target discipline, and threat timing.

Primary Win Conditions

• Regent finish: Prioritize Scavenger Regent or Marang River Regent after Caustic Exhale, Dispelling Exhale, Villainous Wrath, Nameless Inversion, Nowhere to Run, or Strategic Betrayal has reduced the opponent to one or two relevant threats. Setup requires stable blue-black mana, enough life to survive the next attack, and either removal already held up or a visible opponent board that cannot punish a tap-out. Execution is to deploy the Regent, protect the next combat step through removal and priority discipline, then attack only when the engine shows legal attacks that do not expose lethal backswing. Disruption to respect includes visible removal, combat tricks, counterplay, sacrifice pressure, or a board wide enough to ignore one large body. Card text check required for exact Regent stats, triggers, and whether either Regent creates immediate stabilization.

• Advantage-engine close: Prioritize Unholy Annex // Ritual Chamber, Ugin, Eye of the Storms, Draconic Fealty, or Firdoch Core when the game is not immediately about life total and the opponent is likely to run out of threats before this deck runs out of answers. Setup requires at least one answer for the current board or a board state where passing with interaction is worse than committing the engine. Execution is to turn each legal draw, token, transform, damage, or value action into inevitability while continuing to answer the opponent's highest-impact permanent rather than chasing low-value exchanges. Disruption to respect includes opponents pressuring the engine before it generates value, forcing mana to be spent defensively, or presenting a must-answer threat on the same turn. Card text check required for every specific mode of Unholy Annex // Ritual Chamber, Ugin, Eye of the Storms, Draconic Fealty, and Firdoch Core.

• Creature-land and utility-land pressure: Prioritize Fountainport, Soulstone Sanctuary, and Maelstrom of the Spirit Dragon as a win path when the hand contains mostly answers, the opponent has shown removal for normal creatures, or a permanent threat would walk into visible interaction. Setup requires enough lands that utility activations do not prevent casting Caustic Exhale, Dispelling Exhale, Villainous Wrath, Nowhere to Run, or a Regent on time. Execution is to activate only when the rules engine exposes a legal pressure, token, mana, or attack action and the activation does not lose to the current board. Disruption to respect includes land destruction if visible, tapping effects if visible, instant-speed removal if the land becomes a creature, and the tempo cost of spending mana outside the main answer plan. Card text check required for all utility-land activated abilities.

Secondary Win Conditions

• Small-creature pressure: Use Spirited Simulacrum and Cunning Azurescale as early stabilizers first and secondary attackers second. Prioritize this line when the opponent stumbles on mana, has no profitable attacks, or has already traded resources into removal. Execution is to trade when the exchange protects life total or preserves a higher-ceiling finisher, then shift to attacking after the board is clear. Disruption to respect includes opposing blockers that make attacks low-impact, removal that turns the creature into a tempo loss, and combat tricks that punish unnecessary blocks. Card text check required for exact sizes, enters abilities, death triggers, or card-selection text.

• Removal-backed chip damage: Use any surviving Spirited Simulacrum, Cunning Azurescale, Scavenger Regent, Marang River Regent, tokens from Fountainport, or threats from Soulstone Sanctuary to shorten the game once the opponent is constrained. Prioritize chip damage when hand quality is answer-heavy, the opponent is low on cards, and attacking does not reduce the ability to block a visible counterattack. Do not convert a stabilized control position into a race unless the opponent's visible board, life total, and legal actions make the race favorable.

• Conditional burn or direct-damage finish: Treat Caustic Exhale, Dispelling Exhale, Draconic Fealty, Firdoch Core, Ugin, Eye of the Storms, or Maelstrom of the Spirit Dragon as direct-damage finishers only if the legal action text explicitly exposes damage to opponent, planeswalker, battle, or any target. Prioritize direct damage when it ends the game this turn or removes the blocker/threat that makes combat lethal next turn. Card text check required before assuming any registered card can target the opponent directly.

• Conditional recursion or lock finish: Do not assume this registered 60 has a graveyard-recursion loop, prison lock, or hard inevitability engine without visible legal text. If Unholy Annex // Ritual Chamber, Soulstone Sanctuary, Fountainport, Scavenger Regent, Maelstrom of the Spirit Dragon, or Ugin, Eye of the Storms exposes recursion, repeatable removal, or lock-like actions, use them to answer the current visible route to losing before pursuing maximum value.

Emergency Lines

• Behind on life: Spend Caustic Exhale, Dispelling Exhale, Villainous Wrath, Nameless Inversion, Nowhere to Run, and Strategic Betrayal on the threat that changes the next combat step most, even if a larger future target is possible. Preserve life over speculative engine setup, and block with Spirited Simulacrum or Cunning Azurescale when the trade prevents lethal or buys a turn for a sweeper-like legal action.

• Behind on board: Prioritize Villainous Wrath or any legal multi-target, sweeper, sacrifice, shrink, exile, or bounce mode before committing Scavenger Regent, Marang River Regent, Draconic Fealty, or Ugin, Eye of the Storms. If only single-target answers are available, remove the attacker or engine that represents the fastest clock, not the card with the most abstract value.

• Behind on cards: Shift toward Unholy Annex // Ritual Chamber, Ugin, Eye of the Storms, Strategic Betrayal, Spirited Simulacrum, Cunning Azurescale, Temple of Deceit, or any exposed draw/selection mode once the current board is survivable. Do not spend a full turn drawing or filtering if the visible board already threatens lethal before those cards matter.

• Behind on mana: Sequence Island, Swamp, Drowned Catacomb, Watery Grave, Temple of Deceit, Gloomlake Verge, Fountainport, Soulstone Sanctuary, and Maelstrom of the Spirit Dragon to restore both colors before utility activations. If a hand cannot cast early interaction, mulligan or choose lower-curve legal lines over waiting for expensive Regent or Ugin plays.

• Engines removed: Win by answer density plus any remaining body, token, or creature-land; do not concede strategic agency because Unholy Annex // Ritual Chamber, Draconic Fealty, Ugin, Eye of the Storms, Scavenger Regent, or Marang River Regent is gone. Preserve remaining finishers, but use them defensively if survival requires blocking or trading.

• Opponent recursion, combo, or inevitability pressure: Use Strategic Betrayal, Nowhere to Run, Caustic Exhale, Dispelling Exhale, Villainous Wrath, Nameless Inversion, and any legal exile, discard, counter, or graveyard-impacting mode on the engine piece visible to rules output. If no direct hate exists, shorten the game with the safest available threat while holding interaction for the opponent's public commitment turn.

Resource Model

• Life is a spendable buffer only when it unlocks interaction this turn. Take damage from Watery Grave or delay blocking only when the extra mana lets Caustic Exhale, Dispelling Exhale, Nameless Inversion, Nowhere to Run, Villainous Wrath, Strategic Betrayal, or an engine permanent affect the current board. Against visible pressure, treat life as the resource that buys draw steps, not as a bank for speculative value.

• Cards in hand convert into time through exact answers. Spend one-for-one removal on the permanent that changes the next combat, mana, or engine turn most; hold spare answers only when the board is stable and the opponent is likely to expose a higher-impact target. Do not assume any mode of Caustic Exhale, Dispelling Exhale, Villainous Wrath, Strategic Betrayal, Draconic Fealty, Firdoch Core, or Ugin, Eye of the Storms without rules-engine legal action text. Card text check required.

• Mana converts into control by enabling answer-plus-development turns. Prefer lines that cast interaction and still advance Unholy Annex // Ritual Chamber, Draconic Fealty, Spirited Simulacrum, Cunning Azurescale, Marang River Regent, Scavenger Regent, or Ugin, Eye of the Storms when legal. Avoid Fountainport, Soulstone Sanctuary, or Maelstrom of the Spirit Dragon activations if spending that mana leaves a visible attacker, combo piece, or lethal stack item unanswered.

• Board presence is first a shield and then a clock. Use Spirited Simulacrum and Cunning Azurescale to trade, absorb attacks, or pressure planeswalkers only when the visible exchange protects life or preserves a stronger finisher. Use Marang River Regent, Scavenger Regent, Ugin, Eye of the Storms, and any legal Unholy Annex // Ritual Chamber or Draconic Fealty payoff as finishers after the opponent's best route to winning is contained.

• Graveyard and exile are information zones unless the engine exposes a specific legal use. Track public cards there to estimate remaining removal, threats, and recursion risk, but do not assume this deck has flashback, reanimation, delve, escape, or exile-casting lines. If a registered card offers a graveyard, exile, or sacrifice action, prefer expendable tokens or low-impact permanents over Marang River Regent, Scavenger Regent, Ugin, Eye of the Storms, or an active Unholy Annex // Ritual Chamber unless survival demands it. Card text check required.

• Lands are both mana sources and late-game threats. Hitting land drops matters because the deck wants double-spell turns and utility-land activation windows. Fountainport, Soulstone Sanctuary, and Maelstrom of the Spirit Dragon should become resources only after both colors are available and the current turn's answer requirements are funded.

• Information converts into better timing. If Strategic Betrayal, Unholy Annex // Ritual Chamber, Cunning Azurescale, Temple of Deceit, or another legal action reveals, surveils, scries, or selects cards, use the new public or private information to revise removal timing and threat commitment. Sideboard bullets do not exist for this registered list, so post-board resource planning remains main-deck-only.

Mana Guide

• Keep hands that produce both blue and black by turn two or have a clear engine-legal reason to keep a one-color hand. Black is important for Caustic Exhale, Nameless Inversion, Villainous Wrath, Nowhere to Run, Strategic Betrayal, and Unholy Annex // Ritual Chamber if their costs require black. Blue is important for Dispelling Exhale, Cunning Azurescale, Marang River Regent, and Ugin, Eye of the Storms if their costs require blue. Card text check required for exact costs.

• Sequence lands to maximize untapped interaction first. Lead on Island, Swamp, Watery Grave, Gloomlake Verge, or Drowned Catacomb according to which legal early answer the hand can cast. Use Temple of Deceit when the turn has no urgent one-mana or two-mana answer, or when scrying improves a keep that already has enough life and removal.

• Treat Watery Grave life payment as a tactical decision. Put Watery Grave in untapped when it casts immediate interaction, enables a two-spell turn, or prevents a missed curve into Unholy Annex // Ritual Chamber, Draconic Fealty, Marang River Regent, Scavenger Regent, or Ugin, Eye of the Storms. Put it in tapped when life is under pressure and no legal action needs the mana now.

• Deploy utility lands after color stability. Fountainport, Soulstone Sanctuary, and Maelstrom of the Spirit Dragon are valuable late, but early hands with only utility-color uncertainty should be mulliganed more often than hands with clean Island, Swamp, Drowned Catacomb, Watery Grave, Gloomlake Verge, or Temple of Deceit access.

• Play lands before draw or selection when the legal action needs the mana this turn. If Temple of Deceit, Cunning Azurescale, Spirited Simulacrum, Unholy Annex // Ritual Chamber, or another legal action draws or filters without needing a land decision first, delay the land drop when seeing one extra card can choose between tapped, untapped, color, or utility land. Do not delay a land drop past a required mana payment or an exposed landfall-like action unless the engine confirms the action remains legal.

• Mulligan mana-light hands that cannot interact. A two-land hand with both colors and Caustic Exhale, Dispelling Exhale, Nowhere to Run, Nameless Inversion, or Villainous Wrath is usually functional if the costs line up. A hand with only expensive Regent, Ugin, Eye of the Storms, Draconic Fealty, or Unholy Annex // Ritual Chamber and no early interaction needs a strong visible matchup reason to keep.

• Preserve mana for priority windows when the opponent can punish a tap-out. If the stack, combat step, or visible board implies a must-answer action may occur, pass with Caustic Exhale, Dispelling Exhale, Nameless Inversion, Nowhere to Run, Villainous Wrath, or Strategic Betrayal mana available instead of activating Fountainport, Soulstone Sanctuary, Maelstrom of the Spirit Dragon, Firdoch Core, or a value engine.

Mulligan Guide

• Strong keep: keep three lands with both colors plus at least two early interactive cards such as Caustic Exhale, Dispelling Exhale, Nameless Inversion, Nowhere to Run, Villainous Wrath, or Strategic Betrayal, especially when one land can enter untapped. This hand buys time, hits land drops, and lets the deck choose when to commit Unholy Annex // Ritual Chamber, Draconic Fealty, Cunning Azurescale, or Spirited Simulacrum.

• Strong keep: keep two lands with both colors, one cheap answer, and a clear turn-three or turn-four development card such as Unholy Annex // Ritual Chamber, Draconic Fealty, Cunning Azurescale, Firdoch Core, or Spirited Simulacrum if the engine confirms the costs line up. This is better on the draw because the extra card reduces missed-land risk.

• Medium keep: keep three or four lands with Caustic Exhale or Dispelling Exhale plus one finisher or engine card, but downgrade the hand if the first two lands are Fountainport, Soulstone Sanctuary, Maelstrom of the Spirit Dragon, or Temple of Deceit without reliable colors. Card text check required for exact early costs.

• Risky keep: keep one-color hands only when they have multiple castable early plays and at least one strong draw or selection path from Temple of Deceit, Cunning Azurescale, Spirited Simulacrum, Unholy Annex // Ritual Chamber, or another legal action. Ship one-color hands that cannot cast interaction before the opponent's first meaningful attack or engine turn.

• Automatic ship: ship zero-land, one-land without Temple of Deceit or cheap legal selection, five-plus-land hands with no Caustic Exhale, Dispelling Exhale, Nowhere to Run, Villainous Wrath, Strategic Betrayal, or Unholy Annex // Ritual Chamber, and hands made mostly of Marang River Regent, Scavenger Regent, Ugin, Eye of the Storms, Draconic Fealty, or utility lands with no early bridge.

• Matchup-dependent keep: keep removal-heavy hands against visible creature pressure even if they lack Unholy Annex // Ritual Chamber, but require a card-advantage or finisher plan against slower opponents. Against fast starts, prioritize Caustic Exhale, Nameless Inversion, Nowhere to Run, Villainous Wrath, Spirited Simulacrum, and Cunning Azurescale over expensive Regent hands.

• Play/draw adjustment: on the play, keep cleaner mana and earlier action because missing the first interactive window can lose tempo. On the draw, accept slightly slower hands with both colors, removal, and Unholy Annex // Ritual Chamber or Ugin, Eye of the Storms because the extra card improves land-drop reliability.

• Trap hand: do not keep a hand that looks powerful because it contains Marang River Regent, Scavenger Regent, Ugin, Eye of the Storms, and Draconic Fealty if it cannot answer turns two and three. Do not keep a hand that has many answers but only utility lands unless the legal costs are already castable.

Turn Arc

• Turn 1: prioritize untapped color access over value. Play Island, Swamp, Watery Grave, Gloomlake Verge, or Drowned Catacomb according to the cheapest legal interaction in hand; use Temple of Deceit when no immediate answer is required and the scry can fix land or action quality. Delay Fountainport, Soulstone Sanctuary, and Maelstrom of the Spirit Dragon unless they are the only legal land that preserves the curve.

• Turn 2: hold up Caustic Exhale, Dispelling Exhale, Nameless Inversion, Nowhere to Run, or Strategic Betrayal when the opponent can commit a threat, engine, or stack action worth answering. Deploy Spirited Simulacrum or Cunning Azurescale only when blocking, trading, or developing is better than preserving an answer window. Card text check required for exact costs and modes.

• Turn 3: stabilize before investing. Prefer Villainous Wrath, Nowhere to Run, Caustic Exhale, Dispelling Exhale, or Strategic Betrayal if a visible permanent or spell changes combat, mana, or card advantage. Commit Unholy Annex // Ritual Chamber, Draconic Fealty, Firdoch Core, Spirited Simulacrum, or Cunning Azurescale when the board is contained or when the permanent itself is the best stabilization line.

• Turns 4-5: start double-spelling when possible. The preferred pattern is answer plus engine, answer plus blocker, or engine plus protected priority pass. Cast Marang River Regent, Scavenger Regent, or Ugin, Eye of the Storms only when the opponent's current board and open mana do not make tapping out worse than waiting. Use Watery Grave untapped if it unlocks answer-plus-development; preserve life if the same legal line is available tapped.

• Turns 4-5 deviation: against a short clock, spend removal before value even if that delays Unholy Annex // Ritual Chamber, Draconic Fealty, or Ugin, Eye of the Storms. Against a stalled board, shift toward Firdoch Core, utility-land activations, and high-impact permanents, but keep at least one answer available when legal actions show a stack or combat window.

• Late game: convert excess mana into inevitability only after survival is funded. Use Marang River Regent, Scavenger Regent, Ugin, Eye of the Storms, Unholy Annex // Ritual Chamber, Draconic Fealty, Fountainport, Soulstone Sanctuary, Maelstrom of the Spirit Dragon, and Firdoch Core as closing resources when the board is stable. Do not activate utility lands or value engines through visible lethal, a must-answer stack item, or an attack where removal or blocking is required.

Card Roles

• Caustic Exhale is a core early interaction card, so treat it as survival mana before treating it as efficiency. Card text check required for exact targets, timing, and secondary effects; use it when the rules engine shows a legal answer to a creature, combat threat, or permanent that will snowball before your higher-cost engines matter. Hold Caustic Exhale over developing Draconic Fealty, Unholy Annex // Ritual Chamber, Firdoch Core, or a utility-land activation when the opponent has a visible attack, trigger, or stack action that can convert into lethal pressure. Do not spend Caustic Exhale on the first legal target only because mana is available; compare the current target against visible alternatives, known future combat, and whether Villainous Wrath, Nowhere to Run, Nameless Inversion, or Dispelling Exhale covers the same object more cleanly.

• Dispelling Exhale is a priority-window discipline card, so preserve open mana when the opponent can cast or activate something that matters more than a routine board play. Card text check required for exact counter, bounce, removal, or prevention behavior; use it according to the legal action label and visible stack context rather than assuming it covers every spell. Prefer holding Dispelling Exhale against slower decks, combo turns, planeswalker-style threats, or expensive haymakers; prefer tapping out only when the opponent has no meaningful open-window threat or your own permanent creates a stronger clock or lock. Do not burn Dispelling Exhale on low-impact spells if Strategic Betrayal, Caustic Exhale, Nowhere to Run, or Villainous Wrath can answer the resolved object later at lower strategic cost.

• Villainous Wrath is a major stabilizing removal slot, so aim it at threats that decide combat, pressure life total, or protect the opponent's engine. Card text check required for exact speed, target class, and restrictions; if it is sorcery-speed or expensive, plan the turn so mana is not stranded during the opponent's best priority window. Use Villainous Wrath before committing Marang River Regent, Scavenger Regent, or Ugin, Eye of the Storms when the board is unstable. Avoid using Villainous Wrath as a cosmetic cleanup spell if Caustic Exhale, Nameless Inversion, Nowhere to Run, or a profitable block from Spirited Simulacrum or Cunning Azurescale handles the same visible creature.

• Nowhere to Run is targeted interaction with likely tempo or containment value, so deploy it when the legal action text shows it answers an object that other removal may not handle efficiently. Card text check required for exact attachment, debuff, exile, ward, hexproof, or static implications. Use Nowhere to Run to shrink, neutralize, or expose a creature before combat when that changes blocks or prevents damage. Hold it when the opponent's current creature is not the true threat and your hand already has Caustic Exhale or Villainous Wrath for ordinary removal. Do not assume it answers noncreature engines unless the rules engine exposes that legal target.

• Nameless Inversion is the flexible one-copy cheap answer, so save it for the point where its exact legal text matters. Card text check required for current Alchemy legality and interaction with creature types, power/toughness, and damage timing. Use Nameless Inversion for combat math, instant-speed survival, or a threat that would make a higher-cost removal spell awkward. Because it is only one copy, avoid spending it on a replaceable small creature when Caustic Exhale, Nowhere to Run, Spirited Simulacrum, or Cunning Azurescale can cover the same exchange.

• Strategic Betrayal is the one-copy disruption or swing slot, so cast it only when visible information or the legal action label shows a meaningful target. Card text check required for whether it is discard, theft, sacrifice, counterplay, or another effect. Use Strategic Betrayal before committing a fragile finisher if it can remove known interaction, punish a single large threat, or break a board where removal alone is inefficient. Do not fire it blindly into low-value open mana or a board state already controlled by cheaper cards.

• Unholy Annex // Ritual Chamber is a repeated-advantage permanent, so commit it when the board is contained or when the life/card exchange is clearly better than leaving mana up. Card text check required for exact room costs, unlock sequence, triggers, life payments, Demon references, and transformed-room behavior. Play Unholy Annex // Ritual Chamber ahead of expensive finishers in slow games because it can turn land drops and one-for-one answers into inevitability. Delay it against fast creature pressure if casting Caustic Exhale, Villainous Wrath, Nowhere to Run, or a blocker prevents more damage than the room will recover. Do not unlock or activate a room mode through visible lethal or while a must-answer stack item is pending.

• Draconic Fealty is a deck-defining engine or payoff support card, so treat it as a commitment point rather than a filler play. Card text check required for exact cost, Dragon synergies, token generation, counters, card advantage, or mana effects. Cast Draconic Fealty when you can benefit from Marang River Regent, Scavenger Regent, Cunning Azurescale, or other visible Dragon-related actions, or when it independently stabilizes the board. Hold it when the opponent can punish a tap-out and you have Caustic Exhale, Dispelling Exhale, Villainous Wrath, Nowhere to Run, or Strategic Betrayal available. Do not assume Draconic Fealty is worth exposing before the engine confirms relevant follow-up actions.

• Firdoch Core is a four-copy structural card, so use it as a repeatable resource, engine piece, or fixing tool only after preserving required interaction. Card text check required for exact type, cost, activation, and whether it is a spell, artifact, enchantment, creature, or other permanent. Deploy Firdoch Core early when it unlocks mana, card flow, Dragon synergy, or long-game inevitability and the opponent is not presenting an immediate threat. Delay Firdoch Core when holding up Dispelling Exhale or cheap removal is the only line that survives the next turn. Avoid activating Firdoch Core just because the action is legal if that consumes mana needed for Caustic Exhale, Villainous Wrath, Nowhere to Run, or a priority response.

• Cunning Azurescale is an early body and tactical bridge, so use it to buy time, enable synergies, and force the opponent to fight on board before your late game. Card text check required for exact stats, flying, ward, card selection, Dragon status, and triggered abilities. Cast Cunning Azurescale when blocking, pressuring a planeswalker-like permanent, or enabling Draconic Fealty matters more than open interaction. Hold it when mana must represent Caustic Exhale or Dispelling Exhale. In creature matchups, treat Cunning Azurescale as a stabilizer; in slower matchups, treat it as a safe clock only if it does not walk into an avoidable tempo loss.

• Spirited Simulacrum is a two-copy bridge card, so use it to smooth the transition from early defense to late inevitability. Card text check required for exact stats, death trigger, token status, card draw, ramp, or artifact/creature implications. Cast Spirited Simulacrum when it blocks profitably, trades while replacing value, or helps reach Ugin, Eye of the Storms, Marang River Regent, Scavenger Regent, or multiple-spell turns. Avoid running it out before removal when the opponent's current threat must be answered now. If the legal actions show sacrifice, death, or material synergy, evaluate whether Spirited Simulacrum is the safest expendable object.

• Marang River Regent is a primary top-end creature, so resolve it when it stabilizes immediately or closes the game behind protected interaction. Card text check required for exact cost, stats, Dragon status, evasion, triggered abilities, and removal protection. Prefer Marang River Regent after you have answered the visible battlefield or when you can still hold Caustic Exhale, Dispelling Exhale, or another response. Do not tap out for Marang River Regent into an opponent turn where a known attack, stack threat, or removal spell makes the Regent a tempo liability. In control mirrors or slow games, use Marang River Regent as a finisher after forcing exchanges with cheaper cards.

• Scavenger Regent is the single-copy high-impact finisher, so reserve it for board states where its legal text changes the game more than another answer. Card text check required for exact graveyard interaction, counters, lifegain, Dragon status, exile clause, and combat stats. Use Scavenger Regent when the graveyard, battlefield, or life-total context makes it a stabilizing threat. Do not cast it merely because six or more mana is available if Ugin, Eye of the Storms, Unholy Annex // Ritual Chamber, or an answer-plus-hold-up line is safer.

• Ugin, Eye of the Storms is the premium inevitability card, so commit it when the opponent's board and stack cannot punish the tap-out or when waiting is worse. Card text check required for exact loyalty, static abilities, colorless interactions, removal modes, and card-advantage modes. Use Ugin, Eye of the Storms to turn stabilized games into locked games, answer threats that ordinary removal cannot, or generate repeated value against slower decks. Avoid casting Ugin, Eye of the Storms into visible lethal, a wide board that can immediately remove it, or a stack window where Dispelling Exhale should be held.

• Island, Swamp, Watery Grave, Drowned Catacomb, Gloomlake Verge, and Temple of Deceit are the colored-mana foundation, so sequence them to cast early interaction first and engines second. Use Watery Grave untapped only when the life payment enables a meaningful legal action this turn or next turn. Use Temple of Deceit when the scry can fix a land drop or action density and there is no urgent need for untapped mana. Track whether Drowned Catacomb and Gloomlake Verge enter untapped under current visible land conditions; do not assume perfect mana when the rules engine shows otherwise.

• Fountainport, Soulstone Sanctuary, and Maelstrom of the Spirit Dragon are utility lands, so treat their activations as late-game options after interaction is funded. Card text check required for exact activation costs, token, creature-land, Dragon, color, or card-flow abilities. Play these lands early only when colored mana is already secure or the hand has no alternative. Activate them when the board is stable, when mana would otherwise go unused, or when they create a blocker or threat that matters. Do not let a utility activation consume mana needed for Caustic Exhale, Dispelling Exhale, Villainous Wrath, Nowhere to Run, Strategic Betrayal, Unholy Annex // Ritual Chamber, Marang River Regent, Scavenger Regent, or Ugin, Eye of the Storms.

Interaction Priorities

• Priority: spend Caustic Exhale, Nameless Inversion, Nowhere to Run, Villainous Wrath, or Ugin, Eye of the Storms first on visible threats that either kill you before your next stabilizing turn, invalidate blocking, or snowball through repeated value. Card text check required for exact modes and restrictions; follow the rules-engine legal action list rather than assuming any answer can hit any permanent.

• Priority: hold Dispelling Exhale for stack actions that beat your resolved engines, punish a tap-out, or convert an opponent's tempo turn into a decisive swing. Counter the spell or ability that changes the game state most, not the first legal spell by default. Against fast creature decks, counter the payoff or protection effect when removal can answer the body; against slower decks, counter card advantage, planeswalker-like threats, and finishers before routine removal.

• Priority: use Strategic Betrayal only when the legal prompt shows a meaningful hand, permanent, discard, exile, theft, or selection decision. Card text check required. If it exposes opponent choices, take the card or object that beats your current answer suite first; if multiple legal choices are close, prefer the one that protects Unholy Annex // Ritual Chamber, Draconic Fealty, Marang River Regent, Scavenger Regent, or Ugin, Eye of the Storms.

• Priority: remove engines before damage-only creatures when the opponent's visible board is not yet lethal. Kill repeatable card advantage, mana acceleration, sacrifice outlets, anthem effects, or permanent-based combo pieces before ordinary attackers if your life total remains above the next-turn danger threshold. If the opponent can attack you below 6 life next turn, shift removal toward immediate attackers unless an engine is clearly the source of lethal.

• Priority: answer evasive, haste, or must-block threats earlier than ground creatures that Spirited Simulacrum, Cunning Azurescale, Marang River Regent, or utility-land bodies can contain. Do not spend premium removal on a small creature that is already blanked by a legal block unless it enables sacrifice, counters, convoke-like pressure, or a known combat trick window.

• Priority: ignore low-impact permanents when your current plan is to resolve Ugin, Eye of the Storms or a Regent with protection mana available. Let the opponent keep objects that do not attack profitably, do not draw cards, and do not threaten your engines. This deck wins by preserving answer density; do not turn every legal removal action into a mandatory exchange.

• Priority: bait interaction with lower-commitment plays before exposing Ugin, Eye of the Storms, Scavenger Regent, or Marang River Regent. Firdoch Core, Spirited Simulacrum, Cunning Azurescale, Draconic Fealty, or Unholy Annex // Ritual Chamber may be correct bait when losing them does not collapse the hand. Do not bait with the only card that stabilizes the battlefield.

• Priority: use exile, bounce, or unusual registered-card actions only when the rules engine exposes them as legal and the target is better handled by that mode than by normal removal. No registered card should be assumed to exile or bounce without visible legal action text. Save exile-like effects for recursive threats, graveyard-dependent objects, indestructible-like threats, or cards ordinary destroy/damage actions cannot solve.

Combat And Trading Rules

• Defense: preserve life total until the late game engine is online, then preserve high-impact permanents over small chunks of life. Above 14 life, take damage to keep Spirited Simulacrum or Cunning Azurescale when their future value matters. From 8 to 13 life, trade more aggressively unless a follow-up sweeper or Ugin, Eye of the Storms line is visible. At 7 or less, prioritize survival over card advantage unless the legal action creates immediate stabilization.

• Blocks: trade Spirited Simulacrum for a relevant attacker when the exchange buys a full turn, replaces value, or protects Ugin, Eye of the Storms. Card text check required for exact death or value text. Do not chump with Spirited Simulacrum merely to save 2 or 3 life if the next turn still fails to stabilize.

• Blocks: use Cunning Azurescale as a stabilizing body when it blocks a real clock or pressures a vulnerable opposing permanent. Card text check required for stats, flying, ward, and triggers. Avoid trading it into a replaceable attacker when Draconic Fealty or Regent synergies need a creature or Dragon-like permanent to remain on board.

• Blocks: protect Marang River Regent and Scavenger Regent unless their trade prevents lethal, kills an irreplaceable attacker, or unlocks a winning crack-back. These are not routine blockers after stabilization; they are finishers that shorten the game once removal has cleaned up the board.

• Attacks: attack only when the swing does not expose you to a worse return attack or sacrifice an essential blocker. With one stabilizing creature, leave it back against creature decks unless attacking changes the clock materially. Against control or combo, start attacking earlier with Cunning Azurescale, Spirited Simulacrum, Marang River Regent, Scavenger Regent, or utility-land creatures when the opponent is not pressuring your life total.

• Trades: accept trades that convert cheap creatures into time for Unholy Annex // Ritual Chamber, Draconic Fealty, Marang River Regent, Scavenger Regent, or Ugin, Eye of the Storms. Decline trades that remove your only blocker while the opponent has multiple attackers, unless removal is already legal and funded.

• Protection: keep mana open after committing a finisher when a visible legal response can protect it or stop the opponent's recovery spell. If attacking with Marang River Regent or Scavenger Regent leaves Dispelling Exhale unavailable against the opponent's likely answer, consider passing combat pressure for one turn.

• Archetype shift: against aggro, block early, spend removal before damage compounds, and treat Fountainport, Soulstone Sanctuary, or other utility actions as secondary. Against midrange, trade one-for-one until a Regent or Ugin, Eye of the Storms can dominate. Against control, conserve removal, pressure with resilient or low-commitment threats, and force stack exchanges before committing the premium engine.

Selection And Tutor Rules

• Selection: treat this list as a control deck with pseudo-selection, not as a true tutor deck. No registered card should be assumed to search the library unless the rules engine exposes a legal search, reveal, scry, surveil, draw, discard, transform, or choose-card prompt for that exact source. Card text check required for Firdoch Core, Cunning Azurescale, Marang River Regent, Scavenger Regent, Draconic Fealty, Strategic Betrayal, Unholy Annex // Ritual Chamber, and Ugin, Eye of the Storms.

• Land drops: make the land drop after selection when a visible Temple of Deceit, draw, scry, or card-choice action can change which land should be played. If you already have a required untapped black or blue source for the current turn and no selection action is legal, play the land that preserves future double-spell turns: Watery Grave or Drowned Catacomb for color density, Gloomlake Verge when it unlocks both colors, and Soulstone Sanctuary, Fountainport, or Maelstrom of the Spirit Dragon only when colored requirements are already covered.

• Scry/filter: bottom cards that do not answer the visible problem or advance the next two turns. Against pressure, keep Caustic Exhale, Nameless Inversion, Nowhere to Run, Villainous Wrath, and castable stabilizers over slow engines. Against slower hands or empty boards, keep Unholy Annex // Ritual Chamber, Draconic Fealty, Ugin, Eye of the Storms, Marang River Regent, Scavenger Regent, or Dispelling Exhale over redundant spot removal.

• Draw timing: use legal draw or card-advantage actions before committing a narrow answer when the board is stable and mana remains to interact afterward. Delay a draw-like action if tapping mana would prevent Caustic Exhale, Dispelling Exhale, Nameless Inversion, Nowhere to Run, or Villainous Wrath from answering a visible lethal or engine threat.

• Hand or permanent selection: when Strategic Betrayal or another registered card presents visible opponent cards or permanents, choose the object that beats the current hand first. Prioritize cards that invalidate your removal, remove Unholy Annex // Ritual Chamber or Ugin, Eye of the Storms, create immediate lethal pressure, or force you to spend multiple answers.

• Engine selection: when Unholy Annex // Ritual Chamber, Draconic Fealty, Firdoch Core, Cunning Azurescale, Marang River Regent, Scavenger Regent, or Ugin, Eye of the Storms presents modes or targets, select the line that stabilizes before the line that merely gains value. If life total and board are safe, shift toward repeated card access, durable threats, and actions that keep Dispelling Exhale available.

Priority And Stack Rules

• Priority: pass routine empty-stack priority when no legal action improves the board, protects an engine, pressures a low-life opponent, or stops a visible threat. Do not spend Caustic Exhale, Nameless Inversion, Nowhere to Run, or Villainous Wrath during the opponent's end step just because a target exists; preserve answers for threats that matter.

• Stack: hold Dispelling Exhale for spells or abilities that resolve into a losing battlefield, break your engine, or beat your current answer suite. Let low-impact creatures, redundant removal, and small value spells resolve when you can answer the resulting permanent efficiently with Caustic Exhale, Nameless Inversion, Nowhere to Run, Villainous Wrath, or combat.

• Tap-out gate: commit Unholy Annex // Ritual Chamber, Draconic Fealty, Marang River Regent, Scavenger Regent, or Ugin, Eye of the Storms only when the visible board permits it or when waiting is worse. If the opponent has open mana and a known answer from revealed information, prefer a lower-commitment play unless the engine is required to avoid falling behind.

• Response timing: use instant-speed removal before combat damage when it changes blocks, prevents lethal, kills an attacker with a combat trigger, or stops a creature from receiving a visible pump, protection, or sacrifice benefit. Wait until end step only when the target has no relevant attack, trigger, activated ability, or sacrifice use this turn.

• Combat windows: after attackers, remove the attacker that creates the shortest clock or invalidates your blocks. After blockers, use legal instant-speed actions only when they save a key blocker, convert a trade into a clean win, prevent lethal, or kill a creature that would otherwise survive combat.

• Graveyard and recursion timing: answer graveyard-dependent objects only when the rules engine exposes a legal action and the target matters to the current sequence. Do not assume any registered card exiles a graveyard or stops recursion without visible legal action text. If a graveyard choice is legal, prioritize objects that can be cast, returned, copied, or used for immediate lethal or engine advantage.

• Optional triggers and payments: accept optional triggers or payments from Draconic Fealty, Unholy Annex // Ritual Chamber, Firdoch Core, or other registered cards only when the visible cost does not strand needed interaction. Decline optional value if paying prevents Dispelling Exhale from countering a must-answer stack item or prevents Caustic Exhale, Nameless Inversion, Nowhere to Run, or Villainous Wrath from covering combat.

• Activated abilities: use Fountainport, Soulstone Sanctuary, Maelstrom of the Spirit Dragon, Firdoch Core, or other utility actions after preserving required colored mana for interaction. Activate during the opponent's end step when the action is value-only; activate earlier only when it blocks, fixes mana for a current legal play, pressures a vulnerable opponent, or changes combat math.

Sideboard Map

• Registration: this Dimir Control list has a zero-card sideboard, so every post-game configuration must remain the registered 60. Do not propose adding, removing, or exchanging cards between games; the legal plan is to carry the same main deck into every game and change only mulligan standards, threat valuation, priority timing, and role assignment.

• Sideboard-card coverage: there are no registered sideboard cards. No card is legal to add during sideboarding, and no main-deck card has a legal post-board destination under the current registration.

• Validation rule: reject any sideboard request that names a card outside the registered main deck or claims access to a sideboard card. The only legal post-game deck state contains 4 Caustic Exhale, 2 Cunning Azurescale, 4 Dispelling Exhale, 4 Draconic Fealty, 4 Firdoch Core, 1 Nameless Inversion, 1 Strategic Betrayal, 3 Villainous Wrath, 2 Nowhere to Run, 3 Unholy Annex // Ritual Chamber, 2 Ugin, Eye of the Storms, 1 Scavenger Regent, 2 Spirited Simulacrum, 2 Marang River Regent, and the registered 24 lands.

• Role adjustment: use sideboarding time as a matchup reclassification step. Decide whether the opponent is pressuring life total, attacking the stack, grinding resources, using graveyard recursion, or trying to assemble a single engine, then tune gameplay priorities without altering the list.

• Against aggressive creature decks: preserve the same 60 and lower the keep threshold for early interaction. Value hands with black mana plus Caustic Exhale, Nameless Inversion, Nowhere to Run, or Villainous Wrath over slower hands built around Unholy Annex // Ritual Chamber, Draconic Fealty, Marang River Regent, Scavenger Regent, or Ugin, Eye of the Storms. Reduce main-deck emphasis: speculative tap-out engine turns before the first wave of creatures is controlled.

• Against wide boards: keep the same 60 and treat Villainous Wrath as the key stabilizing card if the rules engine exposes it as a legal answer to multiple creatures or a large board. Do not assume sweeper text if the legal action does not show it; Card text check required. Reduce main-deck emphasis: one-for-one removal on low-impact attackers when a later Villainous Wrath line visibly covers more pressure.

• Against large single threats: preserve removal density by keeping the same 60 and aim answers at the threat that beats your current board. Prioritize Nowhere to Run, Villainous Wrath, Nameless Inversion, Caustic Exhale, and Dispelling Exhale according to legal target, timing, and stack availability. Reduce main-deck emphasis: spending premium interaction on small creatures when a larger visible threat is pending or already known from revealed information.

• Against control: keep the same 60 and shift from survival-first to resource-pressure sequencing. Conserve Caustic Exhale, Nameless Inversion, Nowhere to Run, and Villainous Wrath when they lack meaningful targets, and prioritize resolving or protecting Unholy Annex // Ritual Chamber, Draconic Fealty, Marang River Regent, Scavenger Regent, Cunning Azurescale, and Ugin, Eye of the Storms. Reduce main-deck emphasis: reactive removal held as dead cardboard when a legal utility-land or engine action pressures the opponent.

• Against counterspell-heavy opponents: keep the same 60 and make each premium spell ask a different question. Lead with lower-commitment threats such as Spirited Simulacrum, Cunning Azurescale, Firdoch Core, or Draconic Fealty when they are legal and useful, then commit Unholy Annex // Ritual Chamber, Marang River Regent, Scavenger Regent, or Ugin, Eye of the Storms when the opponent is constrained or when waiting falls behind. Reduce main-deck emphasis: tapping out for the highest-value card into obvious open interaction unless the board demands it.

• Against graveyard or recursion decks: preserve the same 60 and treat graveyard interaction as conditional because no registered sideboard hate exists. Use Strategic Betrayal, Dispelling Exhale, Caustic Exhale, Nowhere to Run, Nameless Inversion, or Villainous Wrath only when the rules engine exposes legal actions that actually interrupt the recursion line. Reduce main-deck emphasis: killing replaceable bodies if the visible recursive engine, enabler, or payoff is the real problem.

• Against combo or engine decks: keep the same 60 and raise the priority of stack interaction and discard-style choices. Use Dispelling Exhale for the spell that starts the engine, protects the engine, or creates the decisive payoff; use Strategic Betrayal only according to visible legal action text and revealed candidates. Reduce main-deck emphasis: sorcery-speed value turns that leave no mana or action for the known combo turn.

• Against midrange: preserve the same 60 and play for two-for-one exchanges plus durable engines. Trade Caustic Exhale, Nameless Inversion, Nowhere to Run, and Villainous Wrath for threats that pressure life total or planeswalker-style engines; reserve Dispelling Exhale for cards that would overload removal or answer Unholy Annex // Ritual Chamber and Ugin, Eye of the Storms. Reduce main-deck emphasis: racing with small bodies when the correct role is answer, stabilize, then dominate.

• Against mana denial or land-pressure decks: keep the same 60 and mulligan for functional colored mana. Prioritize hands with Watery Grave, Drowned Catacomb, Gloomlake Verge, Island, or Swamp that cast early interaction; treat Fountainport, Soulstone Sanctuary, Temple of Deceit, and Maelstrom of the Spirit Dragon as secondary unless colored requirements are already safe. Reduce main-deck emphasis: slow utility-land actions that risk missing black or blue interaction windows.

• Post-game learning: after Game 1, record which main-deck cards were stranded, which answers lacked legal targets, and which threats ended the game, but do not translate that review into illegal sideboard movement. Translate the review into mulligan standards, target priority, stack discipline, and tap-out gates for the next game.

• No-sideboard discipline: do not overcorrect from a single revealed card. Because the registered configuration cannot change, the strongest post-game adjustment is to identify the opponent's pressure axis and choose opening hands plus early sequencing that interact with that axis while preserving the Dimir Control endgame.

Matchup Guidance

• Aggro: keep hands that interact before the opponent's third combat step. Prioritize black mana plus Caustic Exhale, Nameless Inversion, Nowhere to Run, or Villainous Wrath over slow hands built around only Unholy Annex // Ritual Chamber, Draconic Fealty, Marang River Regent, Scavenger Regent, or Ugin, Eye of the Storms. Use Spirited Simulacrum and Cunning Azurescale as stabilizing bodies only when the legal action advances the board without giving up a needed removal window. Card text check required for every Alchemy-specific stabilization line; trust the rules engine's legal actions over assumed printed text.

• Burn: protect life total as a resource only after mana is functional. Avoid unnecessary Watery Grave life payments when another land sequence casts the same interaction on time, and treat Fountainport, Soulstone Sanctuary, Temple of Deceit, and Maelstrom of the Spirit Dragon as secondary lands when colored interaction is urgent. Use Dispelling Exhale on burn spells that are lethal, break a race, or protect a threatening permanent, not on low-impact setup spells. If Unholy Annex // Ritual Chamber or Draconic Fealty asks for a life or tempo commitment, make that tap-out decision only when the visible board and stack allow it.

• Go-wide creature decks: preserve Villainous Wrath for the point where it meaningfully changes the battlefield if the rules engine exposes a legal multi-creature or board-control action. Do not assume sweeper text from the name alone; Card text check required. Use Caustic Exhale, Nameless Inversion, Nowhere to Run, and Dispelling Exhale to bridge early turns, but avoid spending the last clean answer on a replaceable small attacker when the opponent's visible board implies a stronger Villainous Wrath turn. When low on life, trade creatures early rather than holding Spirited Simulacrum or Cunning Azurescale for theoretical value.

• Single-threat decks: aim removal and stack interaction at the one permanent or spell that actually ends the game. Rank Nowhere to Run, Villainous Wrath, Nameless Inversion, Caustic Exhale, and Dispelling Exhale by legal target, timing, and whether the threat is on stack or already resolved. If the opponent is visibly protecting one creature, artifact, enchantment, or planeswalker-style engine, hold interaction until the protection window or decisive attack unless waiting gives up lethal damage. Use Ugin, Eye of the Storms as an endgame answer or trump only when the legal action and mana state support a safe commitment.

• Tempo: spend mana efficiently and deny snowball turns. Keep hands with early land drops, Caustic Exhale, Dispelling Exhale, Nameless Inversion, Nowhere to Run, or a low-curve stabilizer; reject slow hands that need too many tapped lands before interacting. Against open mana, prefer sequences that cast one threat and leave interaction available over tapping out for Marang River Regent, Scavenger Regent, or Ugin, Eye of the Storms into visible pressure. Use Strategic Betrayal only when the legal action reveals or affects a tempo-critical card; do not infer hidden cards beyond public information.

• Midrange: trade one-for-one until a permanent advantage engine can stick. Use Caustic Exhale, Nameless Inversion, Nowhere to Run, and Villainous Wrath on threats that pressure life total, dominate combat, or protect another engine. Save Dispelling Exhale for spells that would outscale removal, answer Unholy Annex // Ritual Chamber, or stop Ugin, Eye of the Storms from taking over. Commit Draconic Fealty, Unholy Annex // Ritual Chamber, Cunning Azurescale, Marang River Regent, Scavenger Regent, or Ugin, Eye of the Storms when the opponent is low on board pressure or when further waiting makes your answers inefficient.

• Control: become the deck that makes repeated must-answer threats while keeping enough interaction for the opponent's highest-impact spell. Do not fire Caustic Exhale, Nameless Inversion, Nowhere to Run, or Villainous Wrath without meaningful targets. Lead with lower-commitment permanents or actions such as Spirited Simulacrum, Cunning Azurescale, Firdoch Core, or Draconic Fealty when legal and relevant, then commit Unholy Annex // Ritual Chamber, Marang River Regent, Scavenger Regent, or Ugin, Eye of the Storms when the opponent is constrained. Dispelling Exhale should fight card-advantage engines, finishers, or answers to your resolved engine rather than routine cantrips unless the stack context says the routine spell is decisive.

• Removal-heavy decks: diversify threats and avoid putting all pressure into one exposed permanent. Value Unholy Annex // Ritual Chamber, Draconic Fealty, Ugin, Eye of the Storms, Firdoch Core, Fountainport, Soulstone Sanctuary, and creature-lands or utility actions when the rules engine exposes them as resilient pressure. Cast Spirited Simulacrum, Cunning Azurescale, Marang River Regent, and Scavenger Regent in an order that taxes different answer types if visible legal actions show distinct card types or abilities. Do not overprotect a creature that has already generated its required value unless losing it opens a lethal crack-back or removes the only clock.

• Combo: identify the commitment turn and hold interaction for the spell, permanent, or triggered sequence that makes the combo real. Use Dispelling Exhale on the enabler, protection spell, or payoff that the visible stack identifies as decisive. Use Strategic Betrayal only from revealed or legal candidate information, and choose the card that disrupts the opponent's next deterministic step rather than the card that is merely expensive. Tap out for Unholy Annex // Ritual Chamber, Draconic Fealty, Marang River Regent, Scavenger Regent, or Ugin, Eye of the Storms only when the opponent cannot visibly punish the window or when waiting is worse because the combo clock is immediate.

• Big mana: pressure their setup while saving interaction for payoffs. Early threats from Spirited Simulacrum, Cunning Azurescale, Draconic Fealty, Firdoch Core, and utility lands matter more than pure draw-go if the opponent is not presenting early creatures. Hold Dispelling Exhale for ramp payoff spells, sweepers, or engine permanents when legal stack actions exist. Use removal only on mana creatures or payoff creatures that change the clock; do not spend Caustic Exhale, Nameless Inversion, Nowhere to Run, or Villainous Wrath on low-impact bodies if a larger threat is predictable from public information.

• Graveyard decks: interact with the enabler or payoff because the registered list has no dedicated sideboard hate. Use Strategic Betrayal, Dispelling Exhale, Caustic Exhale, Nowhere to Run, Nameless Inversion, or Villainous Wrath only when the rules engine exposes a legal action that actually interrupts the recursion, sacrifice, reanimation, or escape-style line. If the graveyard card is already public, track whether it is stale, replayable, or merely present; do not assume it can be used unless the board, mana, and legal actions support that conclusion.

• Artifact/enchantment decks: answer the permanent type only when your card's legal action actually reaches it. Nowhere to Run, Villainous Wrath, Dispelling Exhale, Caustic Exhale, Nameless Inversion, and Strategic Betrayal must be chosen according to current legal text, not inferred from card names. If the opponent's artifact or enchantment is an engine rather than a threat, favor countering or discard-style interaction before it resolves; once it resolves, pivot to racing with Draconic Fealty, Unholy Annex // Ritual Chamber, Ugin, Eye of the Storms, utility lands, and any creature pressure the board supports.

• No-sideboard matchups: keep the registered 60 for every pairing and adjust only mulligan standards, target priority, tap-out gates, and combat posture. Because there are no registered sideboard cards, post-game learning should classify the opponent's axis as aggro, burn, tempo, midrange, control, combo, big mana, graveyard, artifact/enchantment, go-wide, single-threat, or removal-heavy, then make the next game start with the cards and sequencing that interact with that axis.

Specific Matchup Notes

• General/archetype-only note: revealed cards, visible board state, stack objects, and legal actions override every matchup assumption. Dimir Control has no registered sideboard, so every post-game plan keeps the same 60 and changes only mulligan discipline, tap-out gates, target priority, and combat posture.

• Aggro and go-wide: prioritize surviving the first pressure wave over preserving premium answers. Keep hands with early black mana plus Caustic Exhale, Nameless Inversion, Nowhere to Run, Villainous Wrath, Spirited Simulacrum, or Dispelling Exhale if the stack exposes a snowball spell. Use removal on creatures that increase damage this turn, enable multiple attackers, or punish blocking; do not save Caustic Exhale for a theoretical larger target while visible attacks are already lethal or near-lethal. Commit Unholy Annex // Ritual Chamber, Draconic Fealty, Marang River Regent, Scavenger Regent, or Ugin, Eye of the Storms only after the board is stable or when the legal action directly stabilizes.

• Burn and spell-heavy tempo: protect life total and avoid tapped-out shields-down turns. Favor untapped blue/black sources when sequencing Island, Swamp, Drowned Catacomb, Watery Grave, Gloomlake Verge, Temple of Deceit, Fountainport, Soulstone Sanctuary, and Maelstrom of the Spirit Dragon. Hold Dispelling Exhale for visible stack actions that represent direct damage, tempo protection, or a card-advantage swing; spend Caustic Exhale, Nameless Inversion, Nowhere to Run, and Villainous Wrath only on creatures that materially shorten the clock. Strategic Betrayal is best when legal candidate information exposes a burn spell, protection spell, or threat that changes the next turn cycle.

• Midrange mirrors: trade resources until one repeatable advantage source can survive. Use removal on threats that outclass Spirited Simulacrum, Cunning Azurescale, Firdoch Core, or Draconic Fealty in combat or invalidate Ugin, Eye of the Storms as a closer. Fight opposing engines with Dispelling Exhale when the stack presents them; otherwise develop Unholy Annex // Ritual Chamber or Draconic Fealty before committing Marang River Regent, Scavenger Regent, or Ugin, Eye of the Storms into unknown answers.

• Control mirrors: become proactive once both players have mana, because waiting forever lets the opponent sculpt. Lead with lower-commitment pressure from Spirited Simulacrum, Cunning Azurescale, Firdoch Core, Draconic Fealty, Fountainport, or Soulstone Sanctuary when legal and useful. Save Dispelling Exhale for opposing finishers, draw engines, discard that would clear the way for a finisher, or removal aimed at the only resolved engine. Strategic Betrayal should take the visible card that breaks a counter war or removes the next must-answer permanent, not the card that merely costs the most.

• Combo and graveyard strategies: identify the first irreversible setup action and interact there. Use Dispelling Exhale on the enabler, payoff, or protection spell named by the stack; use Strategic Betrayal only from revealed or legal candidate cards. Because the list has no graveyard hate, do not spend removal on filler creatures unless Caustic Exhale, Nameless Inversion, Nowhere to Run, or Villainous Wrath actually interrupts the line shown by the engine.

• Big mana and ramp: pressure before the payoff while reserving stack interaction for the payoff. Develop Spirited Simulacrum, Cunning Azurescale, Firdoch Core, Draconic Fealty, and utility-land pressure early if the opponent is not attacking. Use Dispelling Exhale on payoff spells, sweepers, or must-answer engines; use creature removal only on mana creatures or payoff creatures that change the visible clock.

Risk Summary

• Mana risk: the deck needs timely blue and black while several lands may enter tapped or have conditional output. Do not keep hands where Drowned Catacomb, Temple of Deceit, Fountainport, Soulstone Sanctuary, or Maelstrom of the Spirit Dragon leave Caustic Exhale, Dispelling Exhale, Nowhere to Run, Villainous Wrath, Unholy Annex // Ritual Chamber, or Ugin, Eye of the Storms stranded for multiple turns unless the hand already has legal early plays.

• Card-text risk: many Alchemy-specific cards require runtime text verification. Card text check required for Scavenger Regent, Spirited Simulacrum, Cunning Azurescale, Marang River Regent, Firdoch Core, Caustic Exhale, Dispelling Exhale, Draconic Fealty, Strategic Betrayal, Villainous Wrath, Unholy Annex // Ritual Chamber, Ugin, Eye of the Storms, Soulstone Sanctuary, and Maelstrom of the Spirit Dragon before relying on exact modes, targets, triggers, costs, or replacement effects.

• Matchup risk: no sideboard means the deck cannot add narrow hate or extra threats after Game 1. Post-board games must improve through mulligans, target selection, and commitment timing rather than card access.

• Draw risk: hands with only answers can lose to control or big mana, while hands with only engines can die to aggro. Balance each opener around at least one early interaction point or one credible proactive line plus the mana to cast it.

• Over-sideboarding risk: sideboarding is impossible with a 0-card sideboard. Any runtime plan that proposes Side in or Cut actions is illegal and should be rejected.

• Graveyard risk: the registered 60 has no explicit graveyard-hate card. Treat graveyard decks as stack, discard, removal, and race matchups unless legal text from a visible card proves otherwise.

• Sweeper/removal risk: creature closers can be answered, so avoid committing Scavenger Regent, Marang River Regent, Cunning Azurescale, and Spirited Simulacrum into visible sweepers or removal when Unholy Annex // Ritual Chamber, Draconic Fealty, Ugin, Eye of the Storms, Firdoch Core, Fountainport, or Soulstone Sanctuary can diversify pressure.

• Interaction risk: spending Dispelling Exhale on low-impact spells can leave the deck exposed to the actual payoff. Spending Caustic Exhale, Nameless Inversion, Nowhere to Run, or Villainous Wrath on small threats can leave no answer for the creature that matters.

• Sequencing risk: tap-out closers are powerful only when the next turn cycle is survivable. Before casting Unholy Annex // Ritual Chamber, Marang River Regent, Scavenger Regent, or Ugin, Eye of the Storms, check visible attackers, opposing mana, known cards, stack pressure, and whether holding Dispelling Exhale or removal prevents a worse outcome.

Test Feedback Checklist

• Deciding factor: record whether the game was won or lost by early survival, mana development, engine deployment, interaction timing, closing speed, or a single unresolved threat. Tie the answer to visible turns and exact cards such as Caustic Exhale, Dispelling Exhale, Villainous Wrath, Unholy Annex // Ritual Chamber, Draconic Fealty, Marang River Regent, Scavenger Regent, or Ugin, Eye of the Storms.

• Mulligans: note whether each opener had blue, black, castable interaction, and either a proactive engine or enough removal to survive. Flag any keep where Drowned Catacomb, Gloomlake Verge, Watery Grave, Temple of Deceit, Fountainport, Soulstone Sanctuary, or Maelstrom of the Spirit Dragon delayed Caustic Exhale, Dispelling Exhale, Nowhere to Run, Villainous Wrath, Unholy Annex // Ritual Chamber, or Ugin, Eye of the Storms.

• Mana: track every turn where a spell was stranded by color, tapped lands, conditional lands, or utility-land sequencing. Record whether Island, Swamp, Watery Grave, Gloomlake Verge, and Drowned Catacomb supported early interaction, and whether Fountainport, Soulstone Sanctuary, Temple of Deceit, or Maelstrom of the Spirit Dragon created tempo loss or meaningful late utility.

• Velocity: ask whether the deck spent mana every relevant turn without falling behind on board. Mark hands that had removal but no engine, engines but no survival tool, or too many expensive closers before the board was stable.

• Engines: evaluate whether Unholy Annex // Ritual Chamber, Draconic Fealty, Firdoch Core, Cunning Azurescale, Spirited Simulacrum, and Ugin, Eye of the Storms generated material advantage after resolving. Card text check required before attributing exact trigger, mode, or transformation value.

• Removal: review whether Caustic Exhale, Nameless Inversion, Nowhere to Run, and Villainous Wrath were spent on threats that changed the visible clock or protected a key engine. Flag any game where removal was held too long against lethal pressure or spent too early before a larger visible threat.

• Stack interaction: review every Dispelling Exhale decision for target quality. Mark whether it answered a payoff, protected a resolved engine, stopped a tempo swing, or was spent on a low-impact spell that let a later threat resolve.

• Closing: record whether Marang River Regent, Scavenger Regent, Ugin, Eye of the Storms, Soulstone Sanctuary, Fountainport, or creature pressure ended the game quickly after stabilization. Flag games where the deck stabilized but failed to convert before the opponent rebuilt.

• Role: ask whether the pilot correctly shifted between control, tap-out engine, and pressure roles. Identify turns where passing with interaction was better than committing a closer, or where waiting let the opponent gain inevitability.

• Mistakes: log visible mis-sequences, missed land-use opportunities, unnecessary life loss, weak target choices, and tap-out turns that exposed the deck to a known or strongly telegraphed play. Separate pilot errors from rules-engine uncertainty.

• Sideboard: confirm that no sideboard action was proposed or expected because the registered sideboard has 0 cards. If the match loss pattern required post-game adaptation, record the missing role rather than an illegal card movement.

• Overperformers and underperformers: list exact cards that repeatedly won games, stabilized boards, stranded in hand, or failed to answer common threats. Keep conclusions tied to logs, not assumed card text.

First Tuning Questions

• Card quantities: does the deck need more early interaction if aggro losses happen before Unholy Annex // Ritual Chamber, Draconic Fealty, Marang River Regent, or Ugin, Eye of the Storms matter? Compare the performance of Caustic Exhale, Nameless Inversion, Nowhere to Run, and Villainous Wrath by target class and timing.

• Counter density: is 4 Dispelling Exhale enough against control, combo, and big-mana payoffs, or did the deck lose because stack interaction appeared too late? Check whether extra permission would conflict with proactive engine turns.

• Mana base: did Fountainport, Soulstone Sanctuary, Temple of Deceit, or Maelstrom of the Spirit Dragon cost too much tempo relative to their late-game value? Test whether the deck needs more untapped blue-black consistency from Island, Swamp, Watery Grave, Gloomlake Verge, and Drowned Catacomb.

• Aggro plan: did the deck consistently survive the first four turns with removal plus blockers from Spirited Simulacrum, Cunning Azurescale, Firdoch Core, or Draconic Fealty? If not, consider whether the main deck needs cheaper stabilization rather than more top-end.

• Control plan: did the deck present enough must-answer threats, or did it draw too many reactive cards with no pressure? Evaluate whether Unholy Annex // Ritual Chamber, Ugin, Eye of the Storms, Marang River Regent, Scavenger Regent, Fountainport, and Soulstone Sanctuary provided enough inevitability.

• Closer package: which finisher actually ended games after stabilization: Marang River Regent, Scavenger Regent, Ugin, Eye of the Storms, utility-land pressure, or accumulated creature damage? Reduce reliance on closers that were often stranded, answered cleanly, or win-more.

• Engine mix: did Unholy Annex // Ritual Chamber, Draconic Fealty, Firdoch Core, Cunning Azurescale, and Spirited Simulacrum overlap constructively or compete for the same turn window? Card text check required before changing quantities based on exact engine assumptions.

• Sideboard slots: does a 0-card sideboard leave too many post-game matchups unsolved, especially graveyard, aggro, control, or combo patterns? Identify desired role cards by matchup problem before naming candidates.

• Role conflict: does the deck lose more often from being too reactive, too slow to close, or too eager to tap out? Tune only after matching each loss to one of those role failures from replay evidence.

Veles Tactical Policy

Policy: Mulligan For Early Interaction And Colors

Priority: High Decision families: mulligan; mana Cards: Caustic Exhale; Dispelling Exhale; Nowhere to Run; Villainous Wrath; Unholy Annex // Ritual Chamber; Watery Grave; Gloomlake Verge; Drowned Catacomb; Island; Swamp Phase windows: opening hand; mulligan; pregame Runtime cues: prompt:mulligan; visible opening hand; land count; color access Use when: deciding whether the opener can cast black removal, blue interaction, or a stabilizing engine before falling behind. Avoid when: keeping one-color hands that strand the only early spell, or hands with only expensive cards and no visible survival line. Instructions: Keep hands with two to four lands, both colors, and at least one early interactive spell or engine. Treat hands with Caustic Exhale or Nowhere to Run plus correct black mana as stronger against unknown aggression. Treat hands with Dispelling Exhale plus blue mana as stronger against slower or spell-heavy opponents. Card text check required for exact spell timing and restrictions. Pilot skill floor: medium No-API allowed: no Light-model allowed: yes

Policy: Bottom Redundant Top-End After Mulligans

Priority: Medium Decision families: mulligan; selection Cards: Scavenger Regent; Marang River Regent; Ugin, Eye of the Storms; Villainous Wrath; Unholy Annex // Ritual Chamber Phase windows: London mulligan bottom choice Runtime cues: prompt:put cards on bottom; hand after mulligan; land count Use when: a mulligan hand has enough lands and interaction but too many expensive or duplicate payoff cards. Avoid when: the only payoff is needed to win a slow game or the hand already lacks card advantage. Instructions: Bottom excess closers before bottoming cheap interaction. Preserve at least one credible engine or finisher in slow matchups when the mana can cast it. Preserve early removal over a second expensive spell when the opponent has shown fast pressure. Pilot skill floor: medium No-API allowed: no Light-model allowed: yes

Policy: Establish Blue-Black Mana Before Utility Lands

Priority: Medium Decision families: mana Cards: Island; Swamp; Watery Grave; Gloomlake Verge; Drowned Catacomb; Temple of Deceit; Fountainport; Soulstone Sanctuary; Maelstrom of the Spirit Dragon Phase windows: land play; early main phase Runtime cues: prompt:play land; visible hand; available lands; castable actions Use when: choosing land sequencing for turns one through four. Avoid when: a utility land is the only land that enables a required legal action this turn. Instructions: Prioritize untapped blue-black access for Caustic Exhale, Dispelling Exhale, Nowhere to Run, Villainous Wrath, and Unholy Annex // Ritual Chamber. Delay Fountainport, Soulstone Sanctuary, Temple of Deceit, and Maelstrom of the Spirit Dragon when they would prevent casting interaction on curve. Use Watery Grave life payments only when the untapped mana changes a real legal action this turn or protects against a likely near-term threat. Pilot skill floor: medium No-API allowed: no Light-model allowed: yes

Policy: Spend Exact Mana To Preserve Interaction

Priority: Medium Decision families: mana; priority Cards: Caustic Exhale; Dispelling Exhale; Villainous Wrath; Nowhere to Run; Unholy Annex // Ritual Chamber; Ugin, Eye of the Storms Phase windows: casting cost payment; activated ability payment; priority Runtime cues: prompt:pay mana; available mana sources; floating mana; legal follow-up actions Use when: multiple mana payment choices can cast the same spell. Avoid when: Forge exposes only one legal payment or color restrictions make the choice deterministic. Instructions: Preserve blue mana for Dispelling Exhale when the opponent can still cast a meaningful spell. Preserve black mana for Caustic Exhale, Nowhere to Run, Nameless Inversion, and Villainous Wrath when visible board pressure matters. Prefer using mana sources that do not block a planned second spell this turn. Card text check required for exact source restrictions. Pilot skill floor: medium No-API allowed: no Light-model allowed: yes

Policy: Early Engine Commitment Gate

Priority: High Decision families: priority; mana Cards: Unholy Annex // Ritual Chamber; Draconic Fealty; Firdoch Core; Cunning Azurescale; Spirited Simulacrum Phase windows: main phase; post-combat main phase Runtime cues: action:cast Unholy Annex // Ritual Chamber; action:cast Draconic Fealty; action:cast Firdoch Core; action:cast Cunning Azurescale; action:cast Spirited Simulacrum Use when: deciding whether to tap out for the first engine or board-development permanent. Avoid when: the opponent has lethal or a must-answer visible threat and removal is available now. Instructions: Commit an engine when survival is covered, the opponent lacks a visible punished follow-up, or waiting wastes mana without improving the hand. Prefer stabilizing permanents that also block against creature pressure. Hold the engine if passing with Caustic Exhale, Dispelling Exhale, Nowhere to Run, or Villainous Wrath addresses a clearer immediate risk. Pilot skill floor: high No-API allowed: no Light-model allowed: yes

Policy: Permission Commitment With Dispelling Exhale

Priority: High Decision families: interaction; priority Cards: Dispelling Exhale Phase windows: opponent spell on stack; own engine protection window; combat trick window Runtime cues: action:cast Dispelling Exhale; visible stack; opponent mana; known revealed information Use when: a spell on the stack threatens a finisher, engine, life total, or the opponent's central plan. Avoid when: the spell is low impact and a better later target is likely from public information, unless unused mana would otherwise lose the game. Instructions: Spend Dispelling Exhale on spells that change the game state more than a resolved routine creature. Protect Unholy Annex // Ritual Chamber, Ugin, Eye of the Storms, Marang River Regent, or Scavenger Regent when they are the current route to victory. Do not counter merely because mana is available. Pilot skill floor: high No-API allowed: no Light-model allowed: yes

Policy: Removal Triage Against Visible Clock

Priority: High Decision families: interaction; priority Cards: Caustic Exhale; Nameless Inversion; Nowhere to Run; Villainous Wrath Phase windows: opponent combat; opponent end step; own main phase; stack response Runtime cues: action:cast Caustic Exhale; action:cast Nameless Inversion; action:cast Nowhere to Run; action:cast Villainous Wrath; visible attackers; life total Use when: choosing whether and what to remove. Avoid when: removal cannot legally affect the relevant threat or holding it does not create lethal-risk exposure. Instructions: Remove creatures that create lethal, force bad blocks, shut off engine deployment, or invalidate your stabilizing plan. Use the cheapest legal answer that handles the threat while preserving future coverage. Prefer waiting to opponent combat or end step only when that delay does not expose the pilot to extra damage, protection, or a missed legal window. Card text check required for exact target classes. Pilot skill floor: high No-API allowed: no Light-model allowed: yes

Policy: Sweeper Or Multi-Removal Gate

Priority: High Decision families: interaction; priority Cards: Villainous Wrath; Caustic Exhale; Nameless Inversion; Nowhere to Run Phase windows: own main phase; opponent combat; opponent end step Runtime cues: action:cast Villainous Wrath; multiple opposing creatures; visible board pressure Use when: deciding whether to use a broad or expensive removal spell instead of a narrow answer. Avoid when: the same survival result is achieved by a cheaper spell while preserving the larger answer for a wider board. Instructions: Commit Villainous Wrath when it stabilizes a board that single-target removal cannot contain or when waiting risks lethal. Use narrow removal first when one creature is the only relevant threat. Card text check required before assuming whether Villainous Wrath is a sweeper, edict, or targeted answer. Pilot skill floor: high No-API allowed: no Light-model allowed: yes

Policy: Tap-Out Finisher Gate

Priority: High Decision families: priority; mana Cards: Marang River Regent; Scavenger Regent; Ugin, Eye of the Storms Phase windows: own main phase; post-combat main phase Runtime cues: action:cast Marang River Regent; action:cast Scavenger Regent; action:cast Ugin, Eye of the Storms; opponent open mana; visible board Use when: choosing whether to commit a major finisher. Avoid when: passing with interaction prevents lethal or protects an already winning engine. Instructions: Cast a finisher when the board is stable, the opponent is low on resources, or delaying gives them more time than it gives you. Prefer Ugin, Eye of the Storms in stalled states if its visible legal action has broader board impact. Prefer creature closers when pressure is needed and removal risk is acceptable from public information. Card text check required for exact loyalty, creature, and trigger details. Pilot skill floor: high No-API allowed: no Light-model allowed: yes

Policy: Convert Stabilization Into Pressure

Priority: Medium Decision families: combat; priority Cards: Marang River Regent; Scavenger Regent; Cunning Azurescale; Spirited Simulacrum; Firdoch Core; Draconic Fealty; Soulstone Sanctuary; Fountainport Phase windows: beginning of combat; declare attackers; own main phase Runtime cues: prompt:declare attackers; action:activate Soulstone Sanctuary; action:activate Fountainport; visible blockers; opponent life total Use when: the opponent's board is contained and attacks or utility-land actions can shorten the clock. Avoid when: attacking sacrifices the only blocker against a visible crack-back or prevents holding up decisive interaction. Instructions: Attack once the deck has shifted from survival to closing. Keep back creatures that are needed to block lethal or protect Ugin, Eye of the Storms. Use Soulstone Sanctuary or Fountainport only when their legal action does not consume mana needed for Dispelling Exhale or removal this turn. Card text check required for exact activation and token details. Pilot skill floor: medium No-API allowed: no Light-model allowed: yes

Policy: Defensive Combat Discipline

Priority: High Decision families: combat; interaction Cards: Spirited Simulacrum; Cunning Azurescale; Firdoch Core; Draconic Fealty; Caustic Exhale; Nameless Inversion; Nowhere to Run; Villainous Wrath Phase windows: declare blockers; before combat damage; after blockers Runtime cues: prompt:declare blockers; visible attackers; legal removal actions; life total after unblocked damage Use when: blocking decisions affect survival, engine protection, or removal timing. Avoid when: exactly one legal block exists and Forge indicates no alternative choices. Instructions: Block to preserve life total when the visible clock is short. Prefer removal over losing an engine creature when the spell cleanly answers the attacker. Trade expendable creatures when the trade buys the turn needed for Unholy Annex // Ritual Chamber, Ugin, Eye of the Storms, or a finisher. Do not expose a necessary blocker to combat if passing turn would otherwise be safe. Pilot skill floor: high No-API allowed: no Light-model allowed: yes

Policy: Selection And Modal Choices Require Board Context

Priority: Medium Decision families: selection; priority Cards: Strategic Betrayal; Ugin, Eye of the Storms; Unholy Annex // Ritual Chamber; Firdoch Core; Cunning Azurescale; Draconic Fealty Phase windows: spell resolution; triggered ability choice; main phase Runtime cues: prompt:choose mode; prompt:choose card; prompt:select option; visible candidates Use when: Forge exposes multiple modes, card choices, or option candidates from these cards. Avoid when: candidate text is incomplete or the model cannot map the option to visible board consequences. Instructions: Choose the option that solves the current bottleneck: survival first, mana or card flow second, closing speed third. Use Strategic Betrayal as a context-dependent interactive or advantage card only after checking visible legal text. Card text check required for exact mode names, target classes, and hidden-information implications. Pilot skill floor: high No-API allowed: no Light-model allowed: yes

Policy: Target Resolution For Removal

Priority: Medium Decision families: interaction; selection Cards: Caustic Exhale; Nameless Inversion; Nowhere to Run; Villainous Wrath Phase windows: target selection; spell casting; stack response Runtime cues: prompt:choose target; action:target; visible legal targets Use when: a removal spell has multiple legal targets. Avoid when: the target list contains hidden or ambiguous objects the pilot cannot evaluate from visible state. Instructions: Target the object whose removal most improves survival or protects the current win condition. Prefer targets that are attacking, enabling lethal, protecting the opponent's engine, or blocking your only credible clock. Respect Forge legality and do not infer targetability beyond the action list. Pilot skill floor: medium No-API allowed: no Light-model allowed: yes

Policy: Preserve Known Revealed Information Without Inventing It

Priority: Medium Decision families: interaction; selection; priority Cards: Strategic Betrayal; Dispelling Exhale; Caustic Exhale; Nowhere to Run Phase windows: hand-reveal decisions; opponent spell decisions; priority Runtime cues: revealed_info; opponent visible hand; public log history Use when: the state includes revealed opponent cards or stale reveal markers. Avoid when: a card is not currently visible, publicly known, or logged as known to this player. Instructions: Use revealed information to plan counters, removal, and tap-out turns, but treat stale or expired reveal data as uncertain. Do not name or play around hidden cards as certain unless Veles state exposes them. If Strategic Betrayal or another effect asks for a hand or card choice, follow the visible candidate list only. Pilot skill floor: high No-API allowed: no Light-model allowed: yes

Policy: Priority Pass With Interaction Available

Priority: High Decision families: priority; interaction Cards: Dispelling Exhale; Caustic Exhale; Nameless Inversion; Nowhere to Run; Villainous Wrath Phase windows: every priority window; opponent end step; combat steps Runtime cues: action:pass; legal instant-speed actions; visible stack; visible attackers Use when: passing priority could forfeit a chance to answer a current spell, attacker, or lethal setup. Avoid when: no meaningful legal action exists or all legal actions are sorcery-speed after the current window. Instructions: Pass only after confirming that available interaction has no urgent visible target or that holding it has higher expected value. In combat windows, check whether removal before damage changes survival or trades. Against control, check whether passing protects your own future engine turn with Dispelling Exhale. Pilot skill floor: high No-API allowed: no Light-model allowed: yes

Policy: No Sideboard Movement

Priority: High Decision families: sideboard; pregame Cards: none Phase windows: sideboarding; between games; match setup Runtime cues: prompt:sideboard; registered sideboard count 0; legal sideboard options empty Use when: Veles requests sideboarding for this registered deck. Avoid when: the engine reports a nonempty registered sideboard, because that contradicts this specification and requires validation. Instructions: Submit no card movement and do not propose Side in or Cut actions. Adjust only strategic role expectations between games: keep faster hands against aggression, preserve Dispelling Exhale against spell-heavy decks, and prioritize resilient closers against control. Pilot skill floor: low No-API allowed: no Light-model allowed: yes
