Abzan Yawgmoth is a Historic 60-card main deck with a 15-card sideboard, validated under the active Historic contract supplied for Veles. The registered count is legal for the current test target: Main (60) and Sideboard (15). The declared archetype/mechanic tags are combo, midrange, sacrifice, and graveyard; the duplicated source tags should be normalized to that four-tag identity for retrieval and runtime matchup labeling.
The deck is a hybrid Yawgmoth shell rather than a pure stock list. The recognizable core is 4 Yawgmoth, Thran Physician, 4 Young Wolf, 4 Birds of Paradise, 4 Chord of Calling, 3 Agatha's Soul Cauldron, and 2 Grist, the Hunger Tide, but the registered configuration uses Historic-specific and singleton bullets such as 4 Badgermole Cub, 2 Boggart Trawler, 1 Jet Collector, 1 Ouroboroid, 1 Rope Line Attendant, 1 Witch Enchanter, 1 Starting Town, and 1 Wastewood Verge. Runtime strategy must therefore privilege this guide and visible legal actions over generic Yawgmoth heuristics.
The role is creature-combo midrange with a sacrifice engine and graveyard-adjacent backup plans. The deck should be treated as an engine deck that can win by assembling Yawgmoth, Thran Physician with expendable creatures and payoff pressure, but it must also play fair games through mana creatures, Grist, the Hunger Tide, Chord of Calling selection, Agatha's Soul Cauldron value, and resilient board development. The agent should not assume a deterministic combo is available unless the rules engine exposes legal actions and the visible battlefield or graveyard supports them.
The mana identity is Abzan with a green-heavy opening requirement and black/white pressure later. Main-deck lands are 4 Blooming Marsh, 4 Overgrown Tomb, 3 Razorverge Thicket, 2 Forest, 2 Temple Garden, 1 Boseiju, Who Endures, 1 Starting Town, and 1 Wastewood Verge, supported by 4 Birds of Paradise, 3 Delighted Halfling, and 1 Deathrite Shaman. Opening hands that cannot cast early green accelerants or early creatures need skepticism, while hands that depend on unverified colored utility from Starting Town or Wastewood Verge require runtime card-text confirmation before making exact mana assumptions.
The card-text risk profile is moderate because several registered Historic or digital cards may have precise Oracle or Arena text that must be checked at runtime. Card text check required for exact tactical use of Badgermole Cub, Boggart Trawler, Jet Collector, Ouroboroid, Rope Line Attendant, Starting Town, Wastewood Verge, Witch Enchanter, Chittering Illuminator, Juggernaut Peddler, and any Alchemy-adjusted versions such as A-Blood Artist or A-Haywire Mite. The guide may name these cards by role only when that role is supplied by deck construction or visible game text; it must not invent trigger timing, power/toughness, activated abilities, or graveyard functionality.
The sideboard is a flexible hate-and-protection package, not a transformational plan. Registered sideboard cards are 2 Deafening Silence, 2 Endurance, 1 Accursed Marauder, 1 A-Haywire Mite, 1 Archon of Emeria, 1 Chittering Illuminator, 1 Hapatra, Vizier of Poisons, 1 Juggernaut Peddler, 1 Outland Liberator, 1 Strict Proctor, 1 Sylvan Safekeeper, 1 Thalia, Guardian of Thraben, and 1 Voice of Victory. Sideboard guidance must preserve the main engine unless a matchup makes a hate creature more important than speed.
Opponent information status is unknown beyond the active format and no supplied reflection concerns. The decision agent should infer opponent archetype only from public information, revealed cards, game actions, companion or deck metadata if Veles supplies it, and sideboard-stage context. The agent must not name hidden opponent cards as if known; when policy examples need metagame cards, they must stay in prose or use an `opponent:` prefix in policy `Cards:` fields later in the guide.
Abzan Yawgmoth assembles green acceleration, expendable creatures, and a Yawgmoth, Thran Physician decision engine, then converts repeated sacrifice or card-flow prompts into a combo finish or a midrange lock on resources. The most important cards to organize around are 4 Yawgmoth, Thran Physician, 4 Young Wolf, 4 Birds of Paradise, 3 Delighted Halfling, 4 Chord of Calling, 3 Agatha's Soul Cauldron, and 2 Grist, the Hunger Tide; hands and lines should be judged by how quickly they produce mana, bodies, and access to Yawgmoth or a substitute engine.
The deck wins by making small creatures matter more than the opponent's cards. Young Wolf is the cleanest recursive body for sacrifice sequences, mana creatures turn Chord of Calling into a live instant-speed selection tool, and Grist, the Hunger Tide gives the deck a fair battlefield plan when Yawgmoth is absent or unsafe. A-Blood Artist is the registered drain-style payoff only if visible card text confirms the relevant death-trigger or life-total pressure role; do not assume exact Alchemy text without the rules engine exposing it.
The deck is not trying to be a generic Abzan good-stuff pile, a pure hatebears deck, or a normal creature-curve aggro deck. Do not trade away Birds of Paradise, Delighted Halfling, Young Wolf, or random utility creatures just to push minor damage when those bodies enable Chord of Calling, Yawgmoth, Thran Physician, Grist, the Hunger Tide, sacrifice pressure, or Agatha's Soul Cauldron. Do not treat sideboard hate such as Deafening Silence, Archon of Emeria, Thalia, Guardian of Thraben, Strict Proctor, or Voice of Victory as the whole plan unless the matchup demands locking a specific opponent axis.
Prioritize engine access over cosmetic pressure when the game is close. Keep mana stable, preserve at least one sacrifice-friendly creature when Yawgmoth, Thran Physician is visible or findable, and use Chord of Calling as a tactical bridge from board presence into the exact creature the current position asks for. If the rules engine offers a combo commitment, reason about visible removal, opponent pressure, available follow-up bodies, and whether waiting improves or worsens the position before starting the loop.
- Threats: Yawgmoth, Thran Physician is the central threat because it turns expendable creatures into cards, counters, and sacrifice pressure when legal actions allow it. Grist, the Hunger Tide is the fair-game threat that can build material, pressure opposing creatures, and demand attacks away from life totals. Badgermole Cub, Boggart Trawler, Jet Collector, Ouroboroid, Rope Line Attendant, and Witch Enchanter need card-text checks for exact combat or utility roles; use visible text and legal actions rather than assumed function.
- Payoffs: A-Blood Artist is the main-deck life-total payoff only after visible text confirms the payoff trigger or drain function. Hapatra, Vizier of Poisons is a sideboard payoff for -1/-1 counter games and Yawgmoth-style boards when her text is visible and relevant. Agatha's Soul Cauldron can become a graveyard-resource payoff when exiled abilities and counters create real legal actions; do not assume a deterministic loop without engine output.
- Engines: Yawgmoth, Thran Physician plus Young Wolf is the core sacrifice engine, with spare creatures, mana creatures, and token or recursive material extending the chain. Grist, the Hunger Tide is the backup attrition engine. Agatha's Soul Cauldron is the graveyard-adjacent engine that may turn dead creatures into future abilities, but exact use must follow visible exiled cards, counters, and legal activations.
- Velocity: Chord of Calling is the most important selection spell because creature density and mana creatures can convert board presence into the needed creature at instant speed. Green Sun's Zenith is a singleton selection spell for green creature access when legal. Malevolent Rumble and Dredger's Insight are velocity or graveyard-adjacent cards only as their visible text permits; Card text check required for exact selection, milling, or recursion decisions.
- Interaction: Boseiju, Who Endures, Grist, the Hunger Tide, Witch Enchanter, and sideboard cards A-Haywire Mite, Outland Liberator, Accursed Marauder, Endurance, and Strict Proctor form the interaction suite. Treat each as role-specific: artifact/enchantment pressure, creature pressure, graveyard pressure, trigger pressure, or edict pressure, depending on visible text and matchup context.
- Protection: Delighted Halfling may help force key legendary spells through interaction if visible text supports that role. Sylvan Safekeeper and Voice of Victory are sideboard protection cards for creature-engine matchups and interactive opponents; preserve engine creatures before spending protection on minor attackers.
- Recursion: Young Wolf is the primary recursive sacrifice body. Boggart Trawler, Ouroboroid, Deathrite Shaman, Agatha's Soul Cauldron, Dredger's Insight, and Endurance may touch graveyards, but exact recursion, exile, or reshuffle use is conditional on visible rules text.
- Mana: Birds of Paradise, Delighted Halfling, Deathrite Shaman, Blooming Marsh, Overgrown Tomb, Razorverge Thicket, Forest, Temple Garden, Boseiju, Who Endures, Starting Town, and Wastewood Verge define the mana plan. Favor green early, black for Yawgmoth, Thran Physician and sacrifice lines, and white when sideboard hate or utility creatures matter.
- Sideboard modules: Deafening Silence, Archon of Emeria, and Thalia, Guardian of Thraben attack spell-chain decks; Endurance attacks graveyard pressure; A-Haywire Mite and Outland Liberator answer artifacts or enchantments; Accursed Marauder pressures creature-light boards; Hapatra, Vizier of Poisons, Chittering Illuminator, Juggernaut Peddler, Sylvan Safekeeper, Strict Proctor, and Voice of Victory are narrow role upgrades that should enter only when their visible text and matchup pressure justify reducing main-engine density.
- Yawgmoth engine: Prioritize Yawgmoth, Thran Physician plus Young Wolf and at least one other expendable creature when the board is stable enough to spend life and material on sacrifice actions. Setup asks for green acceleration from Birds of Paradise or Delighted Halfling, black access for Yawgmoth, Thran Physician, and bodies that can convoke Chord of Calling. Execute only through legal engine prompts: sacrifice recursive or low-value creatures first, use counters to shrink opposing creatures when relevant, and convert spare life into cards only while the life total and opponent clock leave room. Disruption points are instant-speed removal on Yawgmoth, Thran Physician, graveyard disruption against Young Wolf-style recursion, and pressure that makes life-payment unsafe, so prioritize this line when Yawgmoth is already protected by timing, redundancy, or opponent shields being down.
- Drain payoff finish: Use A-Blood Artist as the dedicated life-total payoff only if visible text confirms the expected death-trigger or drain function. Setup requires A-Blood Artist, Yawgmoth, Thran Physician or another sacrifice outlet exposed by the rules engine, and enough repeatable bodies such as Young Wolf to make deaths matter. Execute by choosing sacrifice sequences that preserve the outlet until the opponent is within visible drain range; do not sacrifice the payoff unless it is lethal, forced, or replaced by another confirmed payoff. Prioritize this line over fair combat when opponent life is low, creature boards are stalled, or drawing extra cards risks losing to a faster visible clock.
- Chord conversion: Treat Chord of Calling as the bridge from ordinary creatures into the current win condition, not merely as generic value. Setup asks for untapped creatures, enough mana, and a clear target need: Yawgmoth, Thran Physician for engine starts, A-Blood Artist for a confirmed drain finish, Archon of Emeria for a spell-chain lock, or a utility creature if visible text answers the board. Execute at the latest useful window when waiting may reveal more information or preserve surprise, but cast earlier if mana or creatures will be lost. Prioritize Chord of Calling when hand lacks the engine, when board bodies would otherwise trade down, or when an opponent end step creates a safe untap with the found card.
- Grist attrition kill: Use Grist, the Hunger Tide as the primary fair-game win condition when Yawgmoth, Thran Physician is absent, removed, or too dangerous to commit. Setup protects Grist, the Hunger Tide with expendable creatures and mana stability, then uses legal loyalty actions to build material, remove threats, or pressure life totals as the engine exposes options. Execute by defending Grist, the Hunger Tide over pushing small attacks unless the attack shortens the clock decisively. Prioritize this line into removal-heavy or counter-heavy opponents, or when the visible board rewards incremental creature production and removal more than a fragile combo attempt.
- Creature pressure: Win fair games by turning Badgermole Cub, Young Wolf, Birds of Paradise, Delighted Halfling, Prosperous Innkeeper, Rope Line Attendant, Jet Collector, Ouroboroid, Boggart Trawler, and utility creatures into a slow combat clock only after their engine value is lower than their combat value. Card text check required for Badgermole Cub, Jet Collector, Ouroboroid, Rope Line Attendant, Boggart Trawler, and Witch Enchanter, so attack or block with them according to visible power, toughness, keywords, and legal actions. Preserve Young Wolf when a future Yawgmoth, Thran Physician or Grist, the Hunger Tide line is likely; trade it aggressively only to protect life, protect Grist, or unlock lethal pressure.
- Hatebear lock pressure: Archon of Emeria can become a main-deck lock or tempo win when its visible text restricts the opponent more than it restricts this deck. Use it to buy time for Yawgmoth, Thran Physician, Grist, the Hunger Tide, or creature combat, especially when opponent lines depend on chaining spells. Do not prioritize Archon of Emeria over engine assembly against creature boards where its restriction does little and your own Chord of Calling or multi-spell turns matter more.
- Graveyard and Cauldron value: Agatha's Soul Cauldron is a secondary engine when visible exiled cards, counters, and activated abilities produce meaningful legal actions. Card text check required for exact ability-transfer and counter details. Use it after important creatures die, when graveyards are contested, or when Yawgmoth, Thran Physician has been answered but creature bodies can still inherit useful abilities. Do not exile your own essential graveyard card if the current line still needs it for recursion, Endurance protection, or future sacrifice loops.
- Selection into silver bullets: Green Sun's Zenith, Malevolent Rumble, and Dredger's Insight support secondary wins by finding or fueling the right permanent when their visible text allows it. Card text check required for Malevolent Rumble and Dredger's Insight. Use these cards to rebuild after removal, find mana or engine access, or increase graveyard density for Agatha's Soul Cauldron decisions; avoid spending them blindly when the current board already presents a safe Yawgmoth, Thran Physician or Grist, the Hunger Tide plan.
- Behind on life: Stop paying life for Yawgmoth, Thran Physician unless the sequence stabilizes immediately, kills the opponent, removes lethal attackers, or finds a life-buffering line confirmed by visible text. Preserve blockers, value Young Wolf as a repeat blocker, and use Chord of Calling defensively for a creature that changes combat or life totals if legal.
- Behind on board: Use Grist, the Hunger Tide, Yawgmoth, Thran Physician counters, Witch Enchanter, Boseiju, Who Endures, or Chord of Calling for interaction only when the legal action text shows the answer fits the permanent or combat problem. Trade mana creatures if survival requires it, but avoid losing all convoke and rebuild capacity unless the alternative is lethal damage.
- Behind on cards: Shift from combo commitment to resource rebuilding with Yawgmoth, Thran Physician draw actions, Grist, the Hunger Tide material, Dredger's Insight, Malevolent Rumble, or Agatha's Soul Cauldron only as visible text supports. Do not cash in the last engine creature for one card if it leaves no path to recover the board.
- Behind on mana: Protect Birds of Paradise, Delighted Halfling, Deathrite Shaman, and land drops over marginal attacks. Use Chord of Calling conservatively because tapping creatures may cost blockers and mana in the same turn.
- Engines removed: If Yawgmoth, Thran Physician is gone or inaccessible, pivot to Grist, the Hunger Tide, Agatha's Soul Cauldron, Chord of Calling for replacement pressure, and fair combat. If A-Blood Artist is removed, continue only with confirmed non-drain kills: Grist pressure, creature attacks, or repeated Yawgmoth, Thran Physician card advantage.
- Graveyard pressure: If opponent graveyard interaction weakens Young Wolf, Agatha's Soul Cauldron, Deathrite Shaman, Boggart Trawler, or Dredger's Insight lines, play from battlefield material and hand instead. Do not force graveyard-dependent execution into visible hate when a fair Grist, the Hunger Tide or Chord of Calling line can keep the game live.
- Life is an engine resource, not a cushion: Spend life on Yawgmoth, Thran Physician only when the sacrifice chain produces a card, shrinks or kills a relevant creature, advances toward A-Blood Artist, or prevents a worse life loss next combat. Stop converting life into cards when the visible clock makes the next attack lethal or when the board no longer contains expendable creatures.
- Hand is mainly a reserve of engines and reloads: Preserve Yawgmoth, Thran Physician, Chord of Calling, Agatha's Soul Cauldron, Grist, the Hunger Tide, Green Sun's Zenith, Dredger's Insight, and Malevolent Rumble until the board or mana makes their legal action high impact. Do not expose duplicate engines into visible sweepers or one-spell-per-turn limits unless waiting lets the opponent pull ahead.
- Mana converts creatures into hidden flexibility: Birds of Paradise, Delighted Halfling, Deathrite Shaman, Prosperous Innkeeper, and convoke creatures let Chord of Calling represent Yawgmoth, Thran Physician, A-Blood Artist, Archon of Emeria, or sideboard bullets at instant speed. Treat untapped creatures as both mana and board presence; tapping the last blocker for Chord of Calling is correct only when the found creature stabilizes, wins, or prevents the attack from mattering.
- Board material is the deck's central currency: Young Wolf is premium sacrifice fodder because it can survive one death under its visible rules text, while Badgermole Cub, Boggart Trawler, Jet Collector, Ouroboroid, Rope Line Attendant, and Witch Enchanter require Card text check required before assigning engine value beyond visible stats and actions. Protect at least one expendable body when Yawgmoth, Thran Physician or Grist, the Hunger Tide is available.
- Graveyard access is conditional value: Use Deathrite Shaman, Agatha's Soul Cauldron, Boggart Trawler, Dredger's Insight, Malevolent Rumble, Endurance, and graveyard-visible choices only from public zones and current legal actions. Do not assume a card in graveyard is usable unless the rules engine offers the action; do not exile your own graveyard card with Agatha's Soul Cauldron if it is still needed for a visible future line.
- Exile is mostly a tracked resource for Agatha's Soul Cauldron and opponent interaction: Read exiled card names, counters, and granted actions exactly as Veles shows them. Card text check required for exact Agatha's Soul Cauldron ability-transfer details, so choose exile targets by visible legal action text and current combo needs rather than assumed oracle text.
- Lands are stability first and utility second: Blooming Marsh, Overgrown Tomb, Razorverge Thicket, Forest, Temple Garden, Starting Town, and Wastewood Verge build early green plus black access; Boseiju, Who Endures is a land until a legal channel-style action visibly answers a permanent that matters more than the land drop.
- Sideboard bullets trade speed for texture: Deafening Silence, Archon of Emeria, Thalia, Guardian of Thraben, Strict Proctor, Voice of Victory, Sylvan Safekeeper, Endurance, A-Haywire Mite, Outland Liberator, Accursed Marauder, Hapatra, Vizier of Poisons, Chittering Illuminator, and Juggernaut Peddler should be valued as narrow tools, not generic upgrades. Card text check required for Chittering Illuminator and Juggernaut Peddler.
- Keep mana only when it casts early development: Prefer hands with green on turn one for Birds of Paradise, Delighted Halfling, Young Wolf, Deathrite Shaman, or Green Sun's Zenith when legal. A hand with Yawgmoth, Thran Physician but no early green or black development should mulligan unless it has multiple lands plus interaction-quality setup from visible card text.
- Prioritize color sequencing as green first, black second, white third: Green enables Birds of Paradise, Delighted Halfling, Young Wolf, Chord of Calling convoke development, Green Sun's Zenith, Malevolent Rumble, Grist, the Hunger Tide, and many sideboard creatures. Black is required for Yawgmoth, Thran Physician and Grist, the Hunger Tide lines; white mainly supports sideboard hate and any visible costs on Archon of Emeria, Rope Line Attendant, Witch Enchanter, Voice of Victory, Thalia, Guardian of Thraben, Strict Proctor, and Deafening Silence.
- Sequence fast lands before they degrade: Play Blooming Marsh or Razorverge Thicket early when they enter untapped under visible rules, especially if they cast a one-drop. Use Overgrown Tomb and Temple Garden life payment only when the untapped mana changes the current turn or the next turn's critical engine timing; preserve life when the same spell can wait without losing tempo.
- Treat utility lands as opportunity costs: Play Boseiju, Who Endures as a land when missing land drops or needing colored development; hold it only when the visible opposing permanent is a high-priority target and the hand already has enough mana. Starting Town and Wastewood Verge require Card text check required, so sequence them according to visible tapped status, available colors, and current legal mana abilities.
- Cast mana creatures before marginal setup spells: Birds of Paradise and Delighted Halfling usually come before Agatha's Soul Cauldron, Dredger's Insight, Malevolent Rumble, or fair attackers because they accelerate Yawgmoth, Thran Physician and enlarge Chord of Calling. Protect Birds of Paradise when it is the only white, black, or fourth mana source.
- Hold land drops before draw or selection when landfall-like information is irrelevant: If casting Yawgmoth, Thran Physician, Dredger's Insight, Malevolent Rumble, Grist, the Hunger Tide, or a legal draw action could reveal a better land need, wait to play the land unless the mana is required to cast the spell. Play the land first when it unlocks Chord of Calling convoke math, pays for interaction, enables a sideboard card, or prevents wasting mana this turn.
- Count Chord of Calling mana from both lands and creatures: Untapped Birds of Paradise, Delighted Halfling, Young Wolf, Badgermole Cub, tokens from Grist, the Hunger Tide, and stray utility bodies may be part of the cost if the rules engine offers convoke. Do not tap creatures whose combat or sacrifice role is more important than the tutored card unless the target solves that loss immediately.
- Plan double-black before committing Yawgmoth lines: Yawgmoth, Thran Physician needs reliable black access, and its activated abilities may ask for additional black mana or discard choices through Veles. Do not rely on Delighted Halfling for nonlegendary or unsupported costs unless Veles exposes the specific mana action.
- Strong keep: Keep two or three lands with green on turn one plus Birds of Paradise or Delighted Halfling and either Yawgmoth, Thran Physician, Chord of Calling, Grist, the Hunger Tide, or Agatha's Soul Cauldron. This hand develops mana, threatens a turn-three engine, and can pivot through removal if it also has Young Wolf or Badgermole Cub.
- Strong keep: Keep land plus Birds of Paradise, Young Wolf, Chord of Calling, and any second land or additional mana creature when Veles shows castable turn-one green. This hand converts early bodies into Chord of Calling pressure and can find Yawgmoth, Thran Physician, A-Blood Artist, Archon of Emeria, or a postboard bullet when the board asks for it.
- Medium keep: Keep three lands, Young Wolf, Badgermole Cub, Grist, the Hunger Tide, and Dredger's Insight when mana colors are stable but acceleration is absent. This hand is slower, so it is better on the play against fair creature decks than on the draw against combo or heavy removal.
- Medium keep: Keep two lands, Agatha's Soul Cauldron, Malevolent Rumble or Dredger's Insight, and early creatures only when at least one early play is legal by turn two. Do not keep a graveyard-value hand that spends the first two turns doing nothing.
- Risky keep: Keep one-land Birds of Paradise only when the land casts Birds of Paradise, the hand has at least one other one-mana play or selection spell, and the matchup is not likely to punish a killed mana creature. Mulligan this hand on the draw against visible or expected cheap removal unless the six-card alternative would be much weaker.
- Risky keep: Keep Yawgmoth, Thran Physician plus Agatha's Soul Cauldron without Young Wolf, Chord of Calling, or enough mana creatures only when the hand has stable lands and a clear turn-two or turn-three play. The engine cards are powerful but do not rescue a hand that cannot create expendable material.
- Automatic ship: Mulligan zero-land hands, one-land hands without a castable Birds of Paradise, Delighted Halfling, Deathrite Shaman, Green Sun's Zenith, or Young Wolf, and hands whose first legal play is turn three. Also ship hands with only white-leaning lands and black spells when Veles does not show early green or black mana.
- Automatic ship: Mulligan hands with multiple Yawgmoth, Thran Physician and no fodder, no acceleration, and no Chord of Calling. Duplicate legendary engines are not a plan unless the hand can cast one and protect or replace it through visible resources.
- Matchup-dependent keep: Against fast spell decks after sideboarding, a hand with Deafening Silence, Thalia, Guardian of Thraben, or Archon of Emeria plus castable mana can be better than a faster but uninteractive engine hand. Against creature pressure, prioritize Young Wolf, Badgermole Cub, Grist, the Hunger Tide, Accursed Marauder, Hapatra, Vizier of Poisons, or Yawgmoth, Thran Physician over narrow tax cards.
- Play/draw adjustment: On the play, accept a slightly slower two-land hand with Birds of Paradise or Delighted Halfling because turn-three Yawgmoth, Thran Physician or Grist, the Hunger Tide can seize initiative. On the draw, require either interaction-quality board presence, a resilient Young Wolf start, or sideboard disruption, because falling behind before the first engine turn is costly.
- Trap hand: Do not keep Chord of Calling, Yawgmoth, Thran Physician, Agatha's Soul Cauldron, Boggart Trawler, Dredger's Insight, and two lands if it has no castable early creature. Chord of Calling is weak without creatures, and the graveyard package is conditional until legal actions prove it matters.
- Turn 1 priority: Cast Birds of Paradise, Delighted Halfling, Deathrite Shaman, Young Wolf, or Green Sun's Zenith only when the legal action advances mana or board material. Prefer Birds of Paradise or Delighted Halfling over Young Wolf when the hand contains Yawgmoth, Thran Physician, Grist, the Hunger Tide, Chord of Calling, or expensive sideboard bullets.
- Turn 1 deviation: Play Young Wolf first when the hand already has enough lands and needs sacrifice fodder more than acceleration. Play Blooming Marsh or Razorverge Thicket early while untapped; use Overgrown Tomb or Temple Garden untapped only if the life payment changes the current turn or a critical turn-two line.
- Turn 2 priority: Add the second body or engine enabler, usually Young Wolf, Badgermole Cub, Agatha's Soul Cauldron, Prosperous Innkeeper, Malevolent Rumble, Dredger's Insight, or another mana creature depending on legal actions. Card text check required for Badgermole Cub, Boggart Trawler, Jet Collector, Ouroboroid, Rope Line Attendant, Witch Enchanter, Starting Town, and Wastewood Verge, so let visible costs, stats, and rules-engine actions decide exact sequencing.
- Turn 2 deviation: Hold Agatha's Soul Cauldron when the graveyard has no relevant public creature card or when casting another creature makes Chord of Calling or Yawgmoth, Thran Physician stronger next turn. Cast postboard Deafening Silence, Thalia, Guardian of Thraben, Voice of Victory, Strict Proctor, A-Haywire Mite, or Outland Liberator only when its visible text attacks the opponent's plan more than another creature advances yours.
- Turn 3 priority: Cast Yawgmoth, Thran Physician when the board has expendable creatures, black mana is stable, and losing one creature to removal does not collapse the turn. If Yawgmoth is unavailable, cast Grist, the Hunger Tide, set up Chord of Calling with untapped creatures, or deploy Agatha's Soul Cauldron plus a creature to prepare a later engine turn.
- Turn 3 deviation: Keep Chord of Calling mana open when the opponent's turn is more likely to reveal the correct target than your main phase is. Main-phase Chord of Calling is preferred only when the found card immediately enables a legal combo, blocks lethal pressure, or locks a spell-based opponent with Archon of Emeria or another visible hate piece.
- Turns 4-5 priority: Convert accumulated creatures into a decisive Yawgmoth, Thran Physician, Chord of Calling, Grist, the Hunger Tide, or Agatha's Soul Cauldron turn. Use Young Wolf and disposable tokens before sacrificing mana creatures unless the mana creature is no longer needed for colors, convoke, or future legal actions.
- Turns 4-5 deviation: Do not tap the last meaningful blocker for Chord of Calling unless the target prevents the next attack, wins, or creates a stronger defensive board. Use Boseiju, Who Endures as interaction only when the visible permanent matters more than the land drop and the rules engine exposes the legal action.
- Late-game priority: Treat every draw step as a search for a compact engine, not raw damage. Chord of Calling should find the missing piece, Agatha's Soul Cauldron should use only visible legal graveyard/exile actions, and Yawgmoth, Thran Physician should turn extra creatures into cards, counters, or lethal only when Veles confirms the actions.
- Late-game deviation: Pivot to fair pressure when graveyards are controlled, Yawgmoth is unavailable, or life totals make sacrifice costs unsafe. Attack with Badgermole Cub, Young Wolf, Boggart Trawler, Jet Collector, Ouroboroid, Rope Line Attendant, Witch Enchanter, and incidental creatures when combat is better than preserving bodies for a nonexistent engine.
- Yawgmoth, Thran Physician is the central engine and should be cast when the board already contains expendable creatures, preferably Young Wolf, Badgermole Cub if its visible text supports fodder value, mana creatures that are no longer needed, or tokens from Grist, the Hunger Tide. Do not run Yawgmoth into open interaction just because it is castable; prefer Chord of Calling at instant speed or a setup turn when losing Yawgmoth leaves no draw engine, no sacrifice outlet, and no pressure. Use Yawgmoth activations only through Veles legal actions, and stop paying life when the visible clock, opposing attackers, or burn-like pressure makes more cards worse than preserving life.
- Young Wolf is premium fodder because it naturally supports sacrifice sequencing and protects the deck from removal-heavy games. Cast it early when the hand already has enough mana or when Yawgmoth, Thran Physician, Chord of Calling, Grist, the Hunger Tide, or Agatha's Soul Cauldron needs a body that can survive one exchange. Do not trade Young Wolf in combat before an engine turn unless the block prevents a meaningful damage race or buys the turn needed to assemble Yawgmoth.
- Birds of Paradise is the fastest color fixer and should usually be the first one-mana play when the hand contains Yawgmoth, Thran Physician, Grist, the Hunger Tide, Chord of Calling, Archon of Emeria, or sideboard hate. Preserve Birds of Paradise for black and white access when legal actions show awkward mana; sacrifice or tap it for convoke only when the current action is worth losing future colors. Against removal-heavy opponents, do not assume Birds survives, so keep hands that still function after it dies.
- Delighted Halfling is acceleration with special value for resolving legendary spells, especially Yawgmoth, Thran Physician and Grist, the Hunger Tide. Lead on Delighted Halfling over Birds of Paradise when the hand’s key play is legendary and the colors remain covered. Do not overvalue the uncounterable angle against creature decks where board material, life total, and blockers matter more than permission resilience.
- Badgermole Cub is a four-copy main-deck role-player, but Card text check required before assigning exact combat, sacrifice, or engine value. Treat it as an early creature whose visible rules text determines whether it is fodder, pressure, selection, or combo material. Cast Badgermole Cub when it improves Chord of Calling, Yawgmoth, Thran Physician, or combat; hold it only when Veles shows a more urgent mana or hate action.
- Agatha's Soul Cauldron is a secondary engine that converts graveyard or exile information into activated-ability leverage only when the rules engine exposes legal actions. Cast it early when a relevant creature card is already public or when the matchup is slow enough that setting up future activated abilities matters. Do not cast Agatha's Soul Cauldron into empty or irrelevant graveyards instead of developing bodies, and do not assume a hidden card will become usable.
- Chord of Calling is the flexible bridge between fair board states and combo turns. Use it at instant speed when waiting can reveal the opponent's action, find Yawgmoth, Thran Physician after removal windows, locate A-Blood Artist for a payoff, or find Archon of Emeria against spell-heavy pressure. Main-phase Chord of Calling is correct when the target immediately changes the current turn, such as enabling a legal engine action, adding a blocker, or deploying a hate creature before the opponent untaps. Avoid tapping essential blockers or color sources for convoke unless the found card clearly stabilizes or wins.
- Grist, the Hunger Tide is both pressure and interaction, and it is strongest when creatures are available to defend it or fuel sacrifice patterns. Cast Grist, the Hunger Tide when the opponent has a creature that must be answered, when a token body improves Chord of Calling, or when a slower matchup rewards a sticky threat. Do not expose Grist on an undefended board if it will die without using a meaningful ability.
- Boggart Trawler is a two-copy main-deck card, but Card text check required for exact tactical use. Treat its visible legal actions as decisive: if it functions as a creature, sequence it as board material for Chord of Calling and sacrifice pressure; if it functions as interaction, graveyard utility, or a modal land-like resource, choose that mode only when Veles shows the current need. Do not rely on undocumented text for combo math.
- Dredger's Insight is a two-copy selection or graveyard-adjacent spell, but Card text check required for exact timing and card movement. Use it when the hand lacks an engine piece, when graveyard setup is valuable for Agatha's Soul Cauldron or Deathrite Shaman, or when the board is stable enough to spend mana on selection. Do not take a low-board-impact Dredger's Insight line under a short visible clock when Yawgmoth, Grist, Chord, or a blocker is available.
- Green Sun's Zenith is a one-copy tutor-style accelerator or toolbox card whose target must be selected from legal choices only. Use it early for a green creature or mana development when that is exposed, and later for the creature that best solves the visible board. Do not name or assume targets that Veles does not present; prefer concrete needs such as mana, fodder, pressure, or a defensive body.
- Malevolent Rumble is a one-copy setup spell, but Card text check required for exact selection and graveyard implications. Cast it when it helps find lands, creatures, or engine pieces according to visible legal action text, especially before a planned Yawgmoth or Chord turn. Avoid it when spending the mana prevents a higher-impact board action.
- A-Blood Artist is the main payoff-style singleton, but Card text check required because the registered name is the Arena variant. Treat it as a likely drain or sacrifice payoff only when visible text confirms that role. Do not tutor for A-Blood Artist unless the current board has sacrifice volume, the opponent's life total makes the payoff relevant, or a deterministic legal line is exposed.
- Archon of Emeria is a main-deck hate singleton and a strong Chord of Calling target against spell-heavy opponents. Cast or tutor Archon of Emeria when limiting spells or mana development is worth slowing your own multi-spell engine turn. Do not deploy it blindly before a turn where you need multiple setup spells unless the opponent's visible plan is more constrained by it than yours is.
- Deathrite Shaman is a one-mana utility creature that can fix, pressure graveyards, and provide reach only when the relevant graveyard cards and legal actions exist. Cast it early when mana or graveyard interaction matters, and preserve it against graveyard decks if its visible abilities are live. Do not assume it can produce mana without legal graveyard resources.
- Prosperous Innkeeper is a stabilizing setup creature when life or mana smoothing matters. Cast it before Yawgmoth, Thran Physician if the life buffer and body make sacrifice lines safer. Do not prioritize it over immediate engine access when life total is high and the opponent is not pressuring combat.
- Jet Collector, Ouroboroid, Rope Line Attendant, and Witch Enchanter are singleton utility cards with Card text check required for exact function. Use them according to exposed legal actions: cast them as bodies when Chord of Calling, Yawgmoth, Thran Physician, or combat needs material, and hold them when their visible text indicates a more valuable timing window. Do not build a line around unverified abilities.
- Blooming Marsh, Razorverge Thicket, Overgrown Tomb, Temple Garden, Forest, Boseiju, Who Endures, Starting Town, and Wastewood Verge define whether the hand can cast early green creatures and later black engine cards. Sequence untapped green sources first for Birds of Paradise, Delighted Halfling, Young Wolf, Green Sun's Zenith, and Badgermole Cub, then secure black for Yawgmoth, Thran Physician and Grist, the Hunger Tide. Use Boseiju, Who Endures as a land unless Veles exposes an opposing permanent whose removal is worth delaying mana development; Card text check required for Starting Town and Wastewood Verge exact utility.
- Priority: Remove creatures that stop sacrifice loops, shorten the clock, or invalidate Yawgmoth, Thran Physician before removing incidental attackers. Use Grist, the Hunger Tide or Yawgmoth, Thran Physician on hate creatures, lethal attackers, lifelink pressure, and creatures that make combat impossible before spending those tools on small utility bodies.
- Priority: Kill or shrink the creature that makes the next turn unsafe when the opponent is racing. Yawgmoth, Thran Physician can convert Young Wolf, Badgermole Cub, Birds of Paradise, Delighted Halfling, or expendable tokens into -1/-1 pressure, but do not sacrifice the last combo body unless the kill prevents lethal damage or unlocks an immediate engine line.
- Priority: Use Boseiju, Who Endures only when Veles shows a legal target whose removal matters more than land development. Artifact, enchantment, or land-like threats that shut off Yawgmoth, Thran Physician, Agatha's Soul Cauldron, Chord of Calling, graveyards, or creature swarms are high-value targets; ignore low-impact mana rocks or decorative permanents when your mana is still constrained.
- Priority: Use Agatha's Soul Cauldron graveyard exile actions for cards with visible activated abilities that matter now or for opponent graveyard cards that visibly enable recursion. Do not exile random graveyard cards just to spend mana, and do not assume hidden graveyard synergies beyond public information.
- Priority: Treat Chord of Calling as interaction when the target answers the current texture. Find Archon of Emeria against spell-chain turns, A-Blood Artist when sacrifice volume threatens a kill, Yawgmoth, Thran Physician when the board has fodder, or a sideboard creature such as Endurance, Accursed Marauder, A-Haywire Mite, Outland Liberator, Strict Proctor, Sylvan Safekeeper, Thalia, Guardian of Thraben, Voice of Victory, Hapatra, Vizier of Poisons, Chittering Illuminator, or Juggernaut Peddler only when its visible text and matchup role justify the tutor.
- Priority: If Veles exposes discard, exile, counter, or bounce from a temporary effect, aim it at the opponent card that stops the engine or wins fastest. Take removal for Yawgmoth, Thran Physician, graveyard hate for Agatha's Soul Cauldron and Deathrite Shaman, sweepers against creature density, or combo pieces before generic card advantage. Counter or bounce choices are not a normal registered-deck plan; use them only from explicit legal actions.
- Bait: Lead with Birds of Paradise, Delighted Halfling, Prosperous Innkeeper, Badgermole Cub, Malevolent Rumble, or Dredger's Insight when the opponent is representing removal and the hand has a stronger Yawgmoth, Thran Physician or Chord of Calling turn. Do not bait with Young Wolf when it is the only resilient sacrifice body.
- Ignore: Let small attackers live when life is high and the board is building toward a Yawgmoth, Thran Physician turn. Ignore nonlethal graveyard value if Endurance, Deathrite Shaman, or Agatha's Soul Cauldron can address it later and current mana must develop the board.
- Preserve the engine before pushing damage. Keep Yawgmoth, Thran Physician, Young Wolf, A-Blood Artist, and the creature count needed for Chord of Calling alive unless a trade prevents lethal damage, removes a must-answer attacker, or enables a visible winning sacrifice line.
- Attack when pressure does not reduce the next engine turn. Young Wolf and expendable bodies can attack into favorable trades, but Birds of Paradise and Delighted Halfling should usually stay back when their mana is needed for Yawgmoth, Thran Physician, Chord of Calling, Grist, the Hunger Tide, or multiple follow-up actions.
- Block aggressively when life total threatens Yawgmoth activations. Above roughly 12 life, prefer preserving bodies and mana unless the opponent's clock is short; from 8 to 11 life, trade expendable creatures for real attackers; at 7 or less, survival takes priority over keeping perfect combo material.
- Trade Young Wolf differently from mana creatures. Young Wolf is the preferred blocker or sacrifice body because it may leave material behind when its visible text confirms resilience; Birds of Paradise and Delighted Halfling are emergency blockers only when mana is no longer the bottleneck or the block prevents lethal.
- Use Yawgmoth, Thran Physician in combat only when the sacrifice sequence changes combat math immediately. Shrink attackers before damage when it saves life or creates a favorable block, and avoid spending life on low-impact shrink actions if the opponent can still present lethal pressure.
- Protect Chord of Calling math during attacks. Do not tap attackers or accept trades that reduce convoke below an important instant-speed Chord of Calling target unless the attack materially pressures planeswalkers, forces lethal pressure, or clears a blocker for a known payoff.
- Defend Grist, the Hunger Tide when it is the active removal plan. Blocking to keep Grist alive is correct when another Grist activation will answer the opponent's best creature or produce bodies; let Grist fall only when your life total or Yawgmoth setup is more important.
- Change posture by archetype. Against aggro, become a stabilizing sacrifice deck and trade bodies early. Against control, attack with spare creatures while holding Chord of Calling and Yawgmoth, Thran Physician for protected windows. Against combo, pressure life totals but keep Archon of Emeria or hate bodies alive. Against graveyard decks, avoid trades that fuel the opponent unless Deathrite Shaman, Endurance, or Agatha's Soul Cauldron can use the graveyard first.
- Tutor for the missing engine piece, not the flashiest card. Use Chord of Calling or Green Sun's Zenith to assemble Yawgmoth, Thran Physician plus sacrifice fodder first, then A-Blood Artist or Hapatra, Vizier of Poisons when the current visible board already supports a kill or overwhelming loop.
- Find Yawgmoth, Thran Physician when the board has expendable creatures and life total allows activations. A hand or battlefield with Young Wolf, Badgermole Cub, Birds of Paradise, Delighted Halfling, Prosperous Innkeeper, or tokens should prioritize turning that material into a live engine over taking a narrow hate creature.
- Find protection or disruption only when the visible matchup demands it. Archon of Emeria is the main-deck tutor target against spell-chain turns; after sideboard, Thalia, Guardian of Thraben, Deafening Silence, Voice of Victory, Sylvan Safekeeper, Endurance, Accursed Marauder, A-Haywire Mite, Outland Liberator, Strict Proctor, Chittering Illuminator, and Juggernaut Peddler require visible text or matchup context before they outrank the engine. Card text check required for Chittering Illuminator and Juggernaut Peddler.
- Sequence Chord of Calling around creature count. Cast cheap creatures before Chord of Calling when they increase convoke and do not expose a key card to a known sweeper; keep creatures untapped when an instant-speed Chord of Calling can answer the opponent or create a lethal Yawgmoth, Thran Physician turn.
- Use Green Sun's Zenith as a sorcery-speed commitment. Choose a green creature that solves the current bottleneck: Birds of Paradise or Delighted Halfling for mana development, Young Wolf for resilient fodder, Deathrite Shaman for graveyard or mana utility when legal text supports it, or a sideboard green creature when its exact visible role matters. Do not assume Green Sun's Zenith can find non-green cards.
- Use Malevolent Rumble and Dredger's Insight before committing a tutor when the hand lacks clear direction. Card text check required for both exact selection patterns; if Veles shows selectable cards, prefer lands or mana creatures when stuck on mana, Yawgmoth, Thran Physician or Chord of Calling when missing the engine, and A-Blood Artist or Agatha's Soul Cauldron only when the sacrifice or graveyard setup is already present.
- Time land drops after known selection only when the legal action sequence permits it. If a draw, reveal, or selection action may find Blooming Marsh, Overgrown Tomb, Razorverge Thicket, Forest, Temple Garden, Boseiju, Who Endures, Starting Town, or Wastewood Verge, consider waiting on the land drop; if a current spell requires mana now, make the land drop first and do not strand development for speculative selection.
- Treat Agatha's Soul Cauldron as selection from public graveyards. Exile the card whose visible activated ability or graveyard denial matters this turn; do not exile a random creature before checking whether Yawgmoth, Thran Physician, Deathrite Shaman, opponent recursion, or a future graveyard line makes another card more important.
- Use instant-speed Chord of Calling at the last safe window. Prefer the opponent's end step for development targets, the beginning of combat or declare attackers step for hate or blocker targets, and response windows for Archon of Emeria, Endurance, A-Haywire Mite, Outland Liberator, Accursed Marauder, Sylvan Safekeeper, or Voice of Victory only when the legal target or effect is visible and relevant.
- Pass priority when no legal action improves the current exchange. Do not fire Yawgmoth, Thran Physician, Agatha's Soul Cauldron, Deathrite Shaman, Boseiju, Who Endures, or Chord of Calling merely because Veles offers the action; preserve life, cards, creatures, and mana until the action changes combat, disrupts a spell, protects the engine, or advances a selected combo turn.
- Activate Yawgmoth, Thran Physician with a purpose. Sacrifice Young Wolf or expendable bodies to shrink a creature, draw toward missing pieces, or begin a visible kill; stop when life total becomes the limiting resource, when the last needed body would be consumed, or when another activation no longer changes the board or hand quality enough to justify the cost.
- Respond to removal by extracting value only when the response is legal and material. If Yawgmoth, Thran Physician is about to die, use available sacrifice activations to draw or remove a creature; if A-Blood Artist or a sideboard protection creature is involved, follow the exact trigger or activated text shown by Veles and do not assume protection works against every effect.
- Let opposing spells resolve when the stack does not threaten the engine, lethal pressure, or a hate permanent. Save Boseiju, Who Endures, Endurance, A-Haywire Mite, Outland Liberator, Deathrite Shaman, and Chord of Calling for spells or permanents that actually affect Yawgmoth, Thran Physician, Agatha's Soul Cauldron, graveyards, creature density, or the life total race.
- Use graveyard interaction at the last informative moment. Endurance, Deathrite Shaman, and Agatha's Soul Cauldron should answer a visible graveyard spell, recursion target, delirium-style threshold, or combo setup after the opponent commits resources when possible; use them earlier only if waiting risks losing the legal window.
- Respect optional triggers and payments as resource decisions. Pay or accept optional value from Prosperous Innkeeper, Rope Line Attendant, A-Blood Artist, Badgermole Cub, Jet Collector, Ouroboroid, Boggart Trawler, Witch Enchanter, and sideboard cards only when Veles exposes the exact trigger or payment and the result advances survival, mana, damage, or engine assembly. Card text check required for uncertain digital or specialized cards.
- Hold priority through combat trick windows when the board can change. After attackers, after blockers, before damage, and after damage, consider Yawgmoth, Thran Physician activations, Chord of Calling, Boseiju, Who Endures, graveyard actions, or sideboard flash/activated effects only if they alter damage, remove a key creature, protect Yawgmoth, Thran Physician, or create lethal sacrifice triggers.
- Sideboard by role first, then by exact card text shown by Veles. The deck should preserve enough cheap creatures, sacrifice material, and Yawgmoth, Thran Physician access that sideboarding does not turn Chord of Calling, Green Sun's Zenith, Agatha's Soul Cauldron, and Grist, the Hunger Tide into disconnected cards.
- Add role cards: Deafening Silence, Archon of Emeria, and Thalia, Guardian of Thraben against spell-chain combo, low-permanent control, and decks trying to cast multiple noncreature spells in one turn. Reduce main-deck emphasis: slow value singletons and clunky selection when the opponent's speed makes incremental cards less important. Deafening Silence is bad when the game is decided by battlefield combat, creature abilities, or one large permanent per turn; Archon of Emeria is bad when its rule effect slows this deck's own double-spell recovery more than the opponent; Thalia, Guardian of Thraben is bad when the hand is heavy on Chord of Calling, Green Sun's Zenith, Dredger's Insight, Malevolent Rumble, Agatha's Soul Cauldron, and Grist, the Hunger Tide and lacks creature pressure.
Spell-chain combo and low-creature control pressure plan
Side in: 2 Deafening Silence; 1 Archon of Emeria; 1 Thalia, Guardian of Thraben; 1 Voice of Victory; 1 Sylvan Safekeeper
- Add role cards: Endurance, Deathrite Shaman support from the main deck, and Agatha's Soul Cauldron emphasis against graveyard combo, recursive threats, and decks whose graveyard is a visible resource. Endurance is strongest when the opponent commits graveyard material before passing priority; it is weaker against fair creature decks where a flash body matters less than a dedicated removal, protection, or engine card. Reduce main-deck emphasis: the slowest uncertain value cards when the matchup asks for immediate graveyard disruption rather than hand smoothing.
Graveyard-centric combo or recursion plan
Side in: 2 Endurance; 1 A-Haywire Mite; 1 Outland Liberator
- Add role cards: Accursed Marauder against decks built around one protected creature, one giant attacker, or a battlefield where targeted removal is unreliable. Accursed Marauder is bad against token boards, sacrifice decks with expendable creatures, and creature-light combo where the opponent can satisfy the edict with a low-value body. Role change: when Accursed Marauder enters, Chord of Calling can become an instant-speed answer to a single visible attacker or protected threat instead of only a Yawgmoth, Thran Physician assembly tool.
Single-large-threat creature plan
Side in: 1 Accursed Marauder; 1 Hapatra, Vizier of Poisons; 1 Sylvan Safekeeper
- Add role cards: A-Haywire Mite and Outland Liberator against artifacts, enchantments, graveyard hate, prison pieces, and permanents that visibly restrict Yawgmoth, Thran Physician or Agatha's Soul Cauldron. A-Haywire Mite is bad when no opposing artifact or enchantment is visible or strongly expected and life gain is not tactically relevant; Outland Liberator is bad when the opponent can ignore a small creature and no target permanent matters. Role change: after these cards enter, keep Chord of Calling mana open more often because removal can be found at instant speed if Veles exposes a legal target window.
Artifact or enchantment pressure plan
Side in: 1 A-Haywire Mite; 1 Outland Liberator; 1 Voice of Victory
- Add role cards: Hapatra, Vizier of Poisons against creature boards where -1/-1 counters, sacrifice loops, or token generation can turn Yawgmoth, Thran Physician activations into a board engine. Hapatra, Vizier of Poisons is bad against creature-light combo, exile-heavy control, and matchups where the deck cannot keep Yawgmoth, Thran Physician alive. Role change: when Hapatra, Vizier of Poisons is present, prioritize preserving life total and bodies for a counter chain rather than spending every creature as generic draw material.
- Add role cards: Sylvan Safekeeper and Voice of Victory against removal-heavy decks and opponents that fight the combo on the stack or during the player's turn. Sylvan Safekeeper is bad when land count is low, mana development is fragile, or the opponent's interaction does not target creatures. Voice of Victory is bad if Veles shows its text is irrelevant to the opponent's interaction pattern; Card text check required before treating it as protection. Role change: after these cards enter, the first tutor target may be protection when Yawgmoth, Thran Physician is already in hand or the visible opponent has shown removal.
Removal-heavy midrange or control plan
Side in: 1 Sylvan Safekeeper; 1 Voice of Victory; 1 Endurance; 1 Accursed Marauder
- Add role cards: Strict Proctor against triggered-ability decks, enters-the-battlefield engines, and opposing permanents whose visible trigger text is essential. Strict Proctor is bad when it taxes this deck's own relevant triggers or when the opponent's plan uses activated abilities, static abilities, combat, or spells that do not rely on triggers. Role change: do not bring Strict Proctor into a Yawgmoth, Thran Physician mirror-like game unless Veles-visible text confirms the tax hurts the opponent more than this deck's creature and value triggers. Card text check required for exact digital implementation.
- Add role cards: Chittering Illuminator and Juggernaut Peddler only when their exact Veles-visible text matches the matchup's bottleneck. Card text check required for both cards before assigning them a tactical role. Chittering Illuminator is bad whenever its text does not immediately improve engine assembly, protection, disruption, or combat math. Juggernaut Peddler is bad whenever its text does not answer a visible pressure point, enable a known Yawgmoth, Thran Physician line, or improve a stalled board.
- Add role cards: Archon of Emeria from the sideboard as the second rule-of-law effect when one copy is not enough or when Green Sun's Zenith and Chord of Calling access make redundant copies important. Sideboard Archon of Emeria is bad against decks where the opponent curves creatures and activated abilities while this deck needs multiple spells to rebuild. Role change: with two Archon of Emeria available, tutor decisions can prioritize the first copy earlier, but only if the current hand can still deploy creatures and lands under its constraint.
- Preserve core counts after every plan. Keep 4 Yawgmoth, Thran Physician, 4 Young Wolf, 4 Birds of Paradise, 4 Badgermole Cub, 3 Delighted Halfling, 3 Agatha's Soul Cauldron, 4 Chord of Calling, and enough lands unless Veles or a matchup-specific plan proves a different registered configuration is legal and tactically superior.
- Reduce main-deck emphasis: Prosperous Innkeeper, Rope Line Attendant, Jet Collector, Malevolent Rumble, Dredger's Insight, Boggart Trawler, Witch Enchanter, and Ouroboroid when their text is slower than the sideboard role being added. Card text check required for uncertain digital cards before lowering their priority; if Veles shows one is essential to the combo or mana, preserve it.
- Aggro: Stabilize with bodies before chasing a perfect combo, because Yawgmoth, Thran Physician needs life total, expendable creatures, and time to convert Young Wolf or Badgermole Cub into control of the board. Keep Birds of Paradise and Delighted Halfling when they accelerate Yawgmoth, Thran Physician or Chord of Calling without leaving the board empty; do not expose every mana creature to combat if one future convoke body is needed. Add role cards: Hapatra, Vizier of Poisons, Accursed Marauder, and Sylvan Safekeeper when the opponent pressures through creatures and the game will turn on one protected engine turn. Reduce main-deck emphasis: slow text-check cards such as Jet Collector, Rope Line Attendant, Malevolent Rumble, or Dredger's Insight when visible pressure makes setup too slow. Card text check required for Badgermole Cub, Jet Collector, Rope Line Attendant, and Dredger's Insight before relying on them as stabilization.
- Go-wide: Prioritize Yawgmoth, Thran Physician plus repeatable sacrifice material over single-answer tutoring, because -1/-1 counter chains can turn many small creatures into cards and board control if life total allows. Use Grist, the Hunger Tide as a board-resource card when Veles shows legal loyalty actions that remove, create, or pressure in a way that buys a Yawgmoth, Thran Physician turn. Add role cards: Hapatra, Vizier of Poisons when counters and token production are visible or rules-engine-confirmed; avoid Accursed Marauder unless one creature is clearly more important than the rest. Preserve A-Blood Artist when sacrifice loops or attrition damage matter, but do not assume lethal without Veles-visible triggers and legal sacrifices.
- Burn: Protect life total as a resource, not a cushion, because Yawgmoth, Thran Physician activations can become unsafe when the opponent represents direct damage. Prioritize Prosperous Innkeeper only if Veles-visible text confirms life gain or another stabilizing role; Card text check required before counting it as life buffer. Add role cards: Endurance if a flash body or graveyard interaction is relevant, Sylvan Safekeeper only when protecting Yawgmoth, Thran Physician is worth lands, and Voice of Victory only if its visible text disrupts the opponent's timing. Reduce main-deck emphasis: painful or slow lines that spend life for marginal cards when the board is not controlled.
- Control: Force the opponent to answer layered threats rather than one all-in spell, using mana creatures, Agatha's Soul Cauldron, Grist, the Hunger Tide, and Chord of Calling to make end-step or protected development matter. Do not cast Yawgmoth, Thran Physician into open interaction just because it is legal unless the hand has redundancy, Sylvan Safekeeper, Voice of Victory, Delighted Halfling protection, or a follow-up Agatha's Soul Cauldron plan. Add role cards: Sylvan Safekeeper, Voice of Victory, Thalia, Guardian of Thraben, Archon of Emeria, and Deafening Silence when the opponent relies on stack interaction, sweepers, or multiple spells per turn. Reduce main-deck emphasis: uncertain creature-value cards that do not tax, protect, recur, or demand removal. Card text check required for Voice of Victory and digital-only cards before treating them as protection.
- Removal-heavy midrange: Trade resources only when the trade leaves a recursive body, a Cauldron line, or a tutor window, because one-for-one games favor the deck when Young Wolf, Badgermole Cub, Grist, the Hunger Tide, and Agatha's Soul Cauldron keep material flowing. Hold Chord of Calling for the opponent's end step when possible, but cast it earlier if Veles shows a removal spell, lethal pressure, or a required answer window. Add role cards: Sylvan Safekeeper, Voice of Victory, Endurance, Hapatra, Vizier of Poisons, and Accursed Marauder according to whether the fight is targeted removal, graveyard value, creature boards, or one protected threat. Preserve 4 Yawgmoth, Thran Physician and 3 Agatha's Soul Cauldron unless the rules engine or sideboard plan proves a different legal configuration.
- Tempo: Respect mana efficiency and board presence over long setup, because a single countered Chord of Calling or bounced Yawgmoth, Thran Physician can lose the turn cycle. Lead with cheap creatures that make future Chord of Calling stronger, and prefer forcing interaction on end steps when the opponent's mana is constrained. Add role cards: Voice of Victory, Thalia, Guardian of Thraben, Archon of Emeria, and Deafening Silence when the opponent needs to chain cheap spells; add Sylvan Safekeeper when the visible interaction targets creatures. Reduce main-deck emphasis: Malevolent Rumble and Dredger's Insight if they do not immediately improve mana, board, or threat density.
- Combo: Decide whether this deck is faster or must disrupt, then commit to either assembling Yawgmoth, Thran Physician plus sacrifice bodies or slowing the opponent with rule-of-law and graveyard tools. Prioritize Archon of Emeria, Deafening Silence, Thalia, Guardian of Thraben, and Chord of Calling access when the opponent needs multiple spells in one turn. Add role cards: Endurance against graveyard setup, A-Haywire Mite or Outland Liberator against artifact or enchantment engines, Strict Proctor against visible trigger-based combo, and sideboard Archon of Emeria for redundancy. Do not assume hate text works; Card text check required for Strict Proctor and any digital card before relying on a lock.
- Graveyard decks: Treat Endurance and Agatha's Soul Cauldron as interaction pieces, not only value cards, because timing matters more than generic pressure when the graveyard is a visible resource. Use Endurance when the opponent has committed graveyard material and Veles offers a legal window that changes the next resolution; avoid firing it into an empty or low-impact graveyard. Preserve Deathrite Shaman when Veles-visible text confirms graveyard interaction in Historic implementation. Add role cards: Endurance, A-Haywire Mite, and Outland Liberator when graveyard engines are supported by artifacts or enchantments. Reduce main-deck emphasis: slow lifegain or uncertain value bodies if immediate graveyard disruption is required.
- Artifact/enchantment decks: Hold Chord of Calling as a toolbox answer when A-Haywire Mite or Outland Liberator can answer a visible permanent that blocks the combo or dominates combat. Use Boseiju, Who Endures only when Veles presents a legal target and the mana/land cost is acceptable; do not assume channel, replacement, or destruction details without engine output. Add role cards: A-Haywire Mite, Outland Liberator, Voice of Victory, and Strict Proctor if the opposing artifact/enchantment plan depends on triggers. Reduce main-deck emphasis: cards that only increase hand smoothing while a hate permanent prevents Yawgmoth, Thran Physician, Agatha's Soul Cauldron, or Chord of Calling from functioning.
- Single-threat decks: Convert tutoring into an answer plan, because Accursed Marauder, Grist, the Hunger Tide, and Yawgmoth, Thran Physician can matter more than racing one oversized creature. Add role cards: Accursed Marauder, Hapatra, Vizier of Poisons, and Sylvan Safekeeper when the game turns on removing, shrinking, or surviving one threat. Avoid sacrificing too many blockers to Yawgmoth, Thran Physician if the next combat step is lethal or forces bad blocks. Keep Chord of Calling mana open when a visible attacker or protected creature must be answered before damage.
- Big mana: Pressure while disrupting setup, because this deck rarely wins by giving the opponent unlimited turns to deploy larger permanents. Use Green Sun's Zenith and Chord of Calling to find the engine or hate creature that best matches visible development, not just the largest creature available. Add role cards: Archon of Emeria, Thalia, Guardian of Thraben, Deafening Silence, A-Haywire Mite, Outland Liberator, and Strict Proctor only when they attack the opponent's actual ramp, spell-chain, artifact, enchantment, or trigger axis. Reduce main-deck emphasis: low-impact grind cards when the opponent's late game invalidates small value.
- Creature midrange mirrors: Build toward an engine turn instead of overtrading, because Yawgmoth, Thran Physician plus Young Wolf, Badgermole Cub, Hapatra, Vizier of Poisons, or Agatha's Soul Cauldron can break stalled boards. Treat combat damage as a way to pressure planeswalkers and life total, but preserve creatures when they are needed for Chord of Calling or sacrifice loops. Add role cards: Hapatra, Vizier of Poisons, Accursed Marauder, Endurance, and Sylvan Safekeeper according to board shape. Card text check required for Ouroboroid, Boggart Trawler, Witch Enchanter, Chittering Illuminator, and Juggernaut Peddler before assigning them matchup-specific jobs.
- General/archetype-only notes apply until Veles reveals exact opposing cards, and revealed cards override assumptions about speed, interaction, graveyard use, and sideboard posture. Use the runtime board, stack, graveyards, hand visibility, and legal action text before applying any matchup shortcut.
- Fast creature decks: Stabilize first, then assemble Yawgmoth, Thran Physician, because sacrificing creatures for cards is dangerous when the next combat step is lethal. Priority targets are one-toughness attackers, anthem-like permanents, and creatures that invalidate blocking. Add role cards: Hapatra, Vizier of Poisons, Accursed Marauder, Prosperous Innkeeper, and Endurance when life, blockers, edicts, or graveyard pressure matter. Reduce main-deck emphasis: slow Dredger's Insight lines and uncertain value bodies when they do not affect combat immediately.
- Spell-chain combo and prowess-style decks: Present Archon of Emeria, Deafening Silence, or Thalia, Guardian of Thraben before spending turns on graveyard value, because a protected rules-tax effect may buy the Yawgmoth, Thran Physician turn. Priority targets are visible engines, cost reducers, graveyard enablers, and permanents that enable multiple spells. Add role cards: Deafening Silence, Archon of Emeria, Thalia, Guardian of Thraben, Endurance, and Voice of Victory. Card text check required for Voice of Victory before treating it as stack protection.
- Removal-heavy midrange: Preserve redundancy over speed, because 4 Yawgmoth, Thran Physician, 3 Agatha's Soul Cauldron, Chord of Calling, Green Sun's Zenith, Young Wolf, and Badgermole Cub let the deck rebuild through one-for-one trades. Priority targets are planeswalkers, graveyard hate, exile removal, and creatures that pressure Yawgmoth, Thran Physician. Add role cards: Sylvan Safekeeper, Voice of Victory, Hapatra, Vizier of Poisons, Endurance, and Accursed Marauder. Avoid exposing the only sacrifice payoff if Veles shows untapped interaction and no follow-up.
- Graveyard decks: Time Endurance and Deathrite Shaman for committed graveyard resources rather than generic value, and treat Agatha's Soul Cauldron as both engine and graveyard-pressure card when legal text supports it. Priority targets are recursive threats, flashback-style spells, reanimation payoffs, and graveyard enablers. Add role cards: Endurance, A-Haywire Mite, Outland Liberator, and Strict Proctor only when the visible engine matches their text. Card text check required for digital or modified implementations before assuming exact graveyard interaction.
- Artifact/enchantment decks: Keep Chord of Calling live for A-Haywire Mite or Outland Liberator when a visible permanent stops Yawgmoth, Thran Physician, Chord of Calling, Agatha's Soul Cauldron, or combat. Priority targets are hate permanents, combo engines, and mana artifacts that let the opponent skip the midgame. Add role cards: A-Haywire Mite, Outland Liberator, Boseiju, Who Endures access, Strict Proctor, and Voice of Victory where applicable.
- Big mana and control: Commit only when waiting is worse, because tapping out for Yawgmoth, Thran Physician into open interaction can lose the deck's best closer. Priority targets are sweepers when known, planeswalkers, artifact/enchantment ramp, and effects that reset the board. Add role cards: Archon of Emeria, Thalia, Guardian of Thraben, Deafening Silence, Sylvan Safekeeper, Voice of Victory, A-Haywire Mite, and Outland Liberator. Use Chord of Calling on end step when possible.
- Mana risk: The deck has strong acceleration but demanding colors, so hands with Birds of Paradise or Delighted Halfling still need visible paths to black for Yawgmoth, Thran Physician and green for Chord of Calling or Green Sun's Zenith. Treat Boseiju, Who Endures, Starting Town, Wastewood Verge, and tapped/shock land choices as tactical costs, not free fixing.
- Matchup risk: The deck can mis-role itself by racing when it should tax, or grinding when it should combo. Reassess after every revealed card, especially when opponent threats show graveyard hate, sweepers, faster combo, or stack interaction.
- Draw risk: Creature-heavy draws without Yawgmoth, Thran Physician, Agatha's Soul Cauldron, Chord of Calling, Green Sun's Zenith, or Grist, the Hunger Tide may flood the battlefield without a payoff. Payoff-heavy draws without Young Wolf, Badgermole Cub, Birds of Paradise, Delighted Halfling, or other fodder may stall before the engine turns on.
- Over-sideboarding risk: Do not dilute the sacrifice engine with too many hate creatures, because Yawgmoth, Thran Physician, Agatha's Soul Cauldron, Chord of Calling, Young Wolf, and Badgermole Cub are the deck's core pressure and recovery structure. Add role cards only when the opponent's visible plan justifies the narrower text.
- Graveyard risk: Opposing graveyard hate can weaken Agatha's Soul Cauldron, Deathrite Shaman lines, and any recursion from Boggart Trawler or other card-text-dependent pieces. Card text check required for Boggart Trawler, Ouroboroid, Witch Enchanter, Jet Collector, Rope Line Attendant, Chittering Illuminator, and Juggernaut Peddler before assigning exact graveyard, protection, or payoff functions.
- Sweeper/removal risk: A board full of mana creatures and fodder can disappear before Chord of Calling or Yawgmoth, Thran Physician converts it into cards. Hold extra creatures when already ahead, and use Sylvan Safekeeper or Voice of Victory only according to verified text and legal action prompts.
- Closer risk: A-Blood Artist may be the cleanest drain payoff, but the deck must not assume lethal drain unless Veles shows the exact legal loop and resulting triggers. Grist, the Hunger Tide and combat damage are fallback closers when the sacrifice loop is interrupted.
- Interaction and sequencing risk: Passing priority, choosing mana sources, sacrificing creatures, and tutoring are all high-leverage decisions. Let Veles legal actions drive execution, and use the light model for commitment choices involving Chord of Calling, Green Sun's Zenith, Yawgmoth, Thran Physician, Agatha's Soul Cauldron, or sideboard hate timing.
- Deciding factor: Identify the turn or decision frame that most changed the game, then record whether it involved Yawgmoth, Thran Physician, Chord of Calling, Agatha's Soul Cauldron, Grist, the Hunger Tide, A-Blood Artist, sideboard hate, or a mana failure.
- Mulligans: Record whether opening hands had a functional mix of mana, early creature, and payoff access, then note if keeping without Birds of Paradise, Delighted Halfling, Young Wolf, Badgermole Cub, Chord of Calling, Green Sun's Zenith, Agatha's Soul Cauldron, or Yawgmoth, Thran Physician led to slow starts.
- Mana: Track every loss where black for Yawgmoth, Thran Physician, green for Chord of Calling or Green Sun's Zenith, or white for sideboard cards was missing, late, or available only through painful Overgrown Tomb or Temple Garden sequencing.
- Velocity: Check whether Dredger's Insight, Malevolent Rumble, Jet Collector, Deathrite Shaman, and Grist, the Hunger Tide increased action density, or whether they delayed board stabilization, combo assembly, or pressure.
- Engine access: Count games where the deck found Yawgmoth, Thran Physician but lacked sacrifice fodder, found Young Wolf or Badgermole Cub but lacked payoff, or drew Agatha's Soul Cauldron without a graveyard or creature context that made it matter.
- Removal and disruption: Record whether Grist, the Hunger Tide, Witch Enchanter, Boseiju, Who Endures, Accursed Marauder, A-Haywire Mite, Outland Liberator, Endurance, Deafening Silence, Archon of Emeria, Thalia, Guardian of Thraben, Strict Proctor, or Hapatra, Vizier of Poisons answered the specific opposing axis shown by public information.
- Sideboard accuracy: After each post-board game, note whether the exact plan reduced too much core engine density or failed to add enough hate, protection, life, removal, artifact/enchantment pressure, or graveyard interaction for the opponent's visible plan.
- Closing: Record whether wins ended through A-Blood Artist drain, Yawgmoth, Thran Physician card flow, Agatha's Soul Cauldron pressure, Grist, the Hunger Tide, combat, or opponent concession, and flag games where the deck stabilized but lacked a clean closer.
- Role assignment: Mark whether the pilot correctly chose combo, midrange, tax-disruption, or survival posture after seeing the opponent's first public signals, and identify any game where the deck kept grinding while a faster combo line was needed.
- Mistakes: Log every priority pass with available Chord of Calling, Yawgmoth, Thran Physician activation, Grist, the Hunger Tide action, sideboard interaction, or lethal/survival block that later looked decisive.
- Stranded cards: Track cards stuck in hand because of mana, timing, target absence, graveyard absence, creature-count shortage, or opponent board state, especially Chord of Calling, Green Sun's Zenith, Yawgmoth, Thran Physician, Agatha's Soul Cauldron, Dredger's Insight, and sideboard one-ofs.
- Overperformers and underperformers: Compare repeated impact from Badgermole Cub, Young Wolf, Birds of Paradise, Delighted Halfling, Grist, the Hunger Tide, A-Blood Artist, Prosperous Innkeeper, Archon of Emeria, Deathrite Shaman, Boggart Trawler, Ouroboroid, Rope Line Attendant, and Witch Enchanter against their role expectations. Card text check required before making final judgments on digital or unfamiliar cards.
- Card quantities: Should the deck increase or reduce Yawgmoth, Thran Physician, Agatha's Soul Cauldron, Chord of Calling, Green Sun's Zenith, Grist, the Hunger Tide, or A-Blood Artist based on whether losses came from missing engines, redundant legends, slow tutors, or insufficient closers?
- Creature base: Should the deck adjust Young Wolf, Badgermole Cub, Birds of Paradise, Delighted Halfling, Prosperous Innkeeper, Deathrite Shaman, Jet Collector, Ouroboroid, Rope Line Attendant, or Boggart Trawler if early bodies were either too low-impact or too essential to cut?
- Mana base: Should Blooming Marsh, Overgrown Tomb, Razorverge Thicket, Forest, Temple Garden, Boseiju, Who Endures, Starting Town, or Wastewood Verge change if the logs show missed black, missed white sideboard spells, painful shocks versus aggro, or too many lands that fail to cast early accelerants?
- Aggro plan: Should Prosperous Innkeeper, Hapatra, Vizier of Poisons, Accursed Marauder, Endurance, or additional removal-style sideboard slots gain priority if fast creature decks repeatedly forced Yawgmoth, Thran Physician activations to become unsafe?
- Control plan: Should Sylvan Safekeeper, Voice of Victory, Archon of Emeria, Thalia, Guardian of Thraben, Deafening Silence, or extra threat density change if removal-heavy opponents repeatedly broke up Yawgmoth, Thran Physician and Agatha's Soul Cauldron before they generated value?
- Combo and spell-chain plan: Should Deafening Silence, Archon of Emeria, Thalia, Guardian of Thraben, Strict Proctor, Endurance, or Voice of Victory occupy more sideboard emphasis if the deck lost before Chord of Calling or Green Sun's Zenith could assemble a protected engine?
- Artifact/enchantment plan: Should A-Haywire Mite, Outland Liberator, Witch Enchanter, Boseiju, Who Endures, or sideboard space for similar roles change if hate permanents or artifact engines repeatedly beat the core plan?
- Closing plan: Should A-Blood Artist remain a one-of, should Grist, the Hunger Tide carry more endgame weight, or should another registered payoff pattern be emphasized if stabilized games still timed out or lost to topdecks?
- Sideboard slots: Which one-of sideboard cards were never searched, cast, or relevant, and did any of Chittering Illuminator, Juggernaut Peddler, Strict Proctor, Voice of Victory, Sylvan Safekeeper, or Hapatra, Vizier of Poisons require a card text check before their slot can be evaluated?
- Role conflicts: Did sideboarding too many tax or hate creatures weaken Chord of Calling, Yawgmoth, Thran Physician, Agatha's Soul Cauldron, Young Wolf, and Badgermole Cub, or did staying too engine-heavy fail to respect the opponent's speed and interaction?
## Veles Tactical Policy
### Policy: Opening Hand Engine Access
Priority: High
Decision families: mulligan
Cards: Birds of Paradise; Delighted Halfling; Young Wolf; Badgermole Cub; Yawgmoth, Thran Physician; Chord of Calling; Agatha's Soul Cauldron
Phase windows: opening hand, mulligan decisions
Runtime cues: prompt:mulligan; visible:opening hand
Use when: deciding keep or mulligan before any game action.
Avoid when: rules engine has already locked the hand or requires London bottom choices.
Instructions: Keep hands with castable mana plus an early creature and either engine access, tutor access, or multiple redundant setup pieces. Reject slow hands that cannot present a creature before turn two or cannot cast green spells. Treat Yawgmoth, Thran Physician plus expendable creatures as a premium keep only when black mana is visible or reliably reachable.
Pilot skill floor: medium
No-API allowed: no
Light-model allowed: yes
### Policy: London Bottom Preservation
Priority: Medium
Decision families: mulligan
Cards: Yawgmoth, Thran Physician; Chord of Calling; Agatha's Soul Cauldron; Birds of Paradise; Delighted Halfling; Young Wolf; Badgermole Cub
Phase windows: London mulligan bottom selection
Runtime cues: prompt:bottom cards; action:put card on bottom
Use when: the kept hand must put one or more cards on bottom.
Avoid when: the engine exposes only one legal bottom set.
Instructions: Preserve at least one green source, one early creature, and the strongest engine access. Bottom redundant legends, late tutors without creature density, and conditional one-ofs before cutting the only accelerator or only sacrifice body.
Pilot skill floor: medium
No-API allowed: no
Light-model allowed: yes
### Policy: First Board Setup
Priority: Medium
Decision families: mana; priority
Cards: Birds of Paradise; Delighted Halfling; Young Wolf; Badgermole Cub; Deathrite Shaman; Prosperous Innkeeper
Phase windows: turns 1-2 main phases
Runtime cues: action:cast Birds of Paradise; action:cast Delighted Halfling; action:cast Young Wolf; action:cast Badgermole Cub
Use when: multiple early creature spells are legal from visible hand and mana.
Avoid when: a survival interaction or decisive hate permanent must be deployed immediately.
Instructions: Lead with mana creatures when they unlock turn-two Yawgmoth, Thran Physician, Chord of Calling, Grist, the Hunger Tide, or multiple spells. Lead with Young Wolf or Badgermole Cub when sacrifice fodder is missing or removal pressure makes a single accelerator too fragile.
Phase windows: all payment prompts, land play decisions
Runtime cues: action:pay; action:choose color; action:play land
Use when: choosing mana sources, colors, or land sequencing from visible legal actions.
Avoid when: only one payment action is legal.
Instructions: Prioritize green on turn one, black for Yawgmoth, Thran Physician, and white only when sideboard or main-deck white spells are visible and castable. Minimize pain from Overgrown Tomb and Temple Garden when life total is pressured, but do not preserve life at the cost of missing engine timing.
Use when: starting a sacrifice loop, tutor-for-engine line, or Cauldron engine line is legal.
Avoid when: visible opponent interaction, missing fodder, low life, or no payoff makes waiting safer.
Instructions: Commit when the board already contains expendable creatures, the line generates cards or lethal drain, or waiting exposes the engine to worse public risk. Account for visible blockers, life totals, graveyard contents, and available mana before sacrificing core bodies.
Use when: selecting sacrifice and target choices for visible Yawgmoth, Thran Physician actions.
Avoid when: life total cannot absorb activation costs or the target text is ambiguous.
Instructions: Sacrifice resilient or expendable creatures before unique engine pieces. Put negative counters where they remove blockers, shrink lethal attackers, or enable additional sacrifice value. Card text check required for Badgermole Cub before treating it as deterministic fodder.
Pilot skill floor: high
No-API allowed: no
Light-model allowed: yes
### Policy: A-Blood Artist Opponent Drain Target
Priority: Low
Decision families: selection
Cards: A-Blood Artist
Phase windows: triggered ability target prompts
Runtime cues: action:target opponent A-Blood Artist
Use when: the legal action text names A-Blood Artist and exactly one opponent target is available.
Avoid when: multiple opponent-controlled replacement, prevention, or redirection effects are visible.
Instructions: Select the opponent as the drain target when the trigger requires a player target and the only strategic plan is reducing the opponent's life total.
Pilot skill floor: low
No-API allowed: yes
Light-model allowed: yes
### Policy: Chord And Zenith Search Gate
Priority: High
Decision families: selection; priority; mana
Cards: Chord of Calling; Green Sun's Zenith; Yawgmoth, Thran Physician; A-Blood Artist; Hapatra, Vizier of Poisons; Endurance; Accursed Marauder; A-Haywire Mite; Outland Liberator; Sylvan Safekeeper
Phase windows: main phases, end steps, response windows
Runtime cues: action:cast Chord of Calling; action:cast Green Sun's Zenith; prompt:search library
Use when: a tutor or search choice is legal.
Avoid when: the search list is hidden, incomplete, or card eligibility is unclear.
Instructions: Search for the missing piece that converts current board into cards, lethal drain, protection, hate, or survival. Prefer Yawgmoth, Thran Physician for engine access, A-Blood Artist for closing loops, Endurance for graveyard emergencies, and artifact/enchantment creatures only when public permanents demand them.
Phase windows: main phases with planeswalker actions legal
Runtime cues: action:activate Grist, the Hunger Tide
Use when: choosing a visible Grist, the Hunger Tide loyalty action.
Avoid when: activating would expose lethal damage or sacrifice the only engine creature.
Instructions: Use Grist, the Hunger Tide to answer must-kill creatures or build material when the battlefield is stable. Do not spend a sacrifice mode on a unique Yawgmoth, Thran Physician or sole combo body unless survival or lethal pressure requires it.
Use when: choosing a graveyard card for Agatha's Soul Cauldron.
Avoid when: target card text or granted ability is uncertain.
Instructions: Prefer cards whose visible text or known role grants immediate engine, disruption, or protection to current creatures. Card text check required for unfamiliar digital cards before treating a target as combo-enabling.
Use when: opponent controls a visible artifact, enchantment, or nonbasic permanent that constrains the engine.
Avoid when: the target does not affect current combat, combo access, mana, or survival.
Instructions: Answer hate that stops sacrificing, searching, graveyard use, spell casting, or lethal combat before spending removal on generic value permanents. Preserve creature-based answers when Chord of Calling can find them at instant speed.
Pilot skill floor: medium
No-API allowed: no
Light-model allowed: yes
### Policy: Tax And Hate Deployment
Priority: Medium
Decision families: priority; pregame; sideboard
Cards: Archon of Emeria; Deafening Silence; Thalia, Guardian of Thraben; Strict Proctor; Voice of Victory
Phase windows: early main phases, post-board games
Runtime cues: action:cast Archon of Emeria; action:cast Deafening Silence; action:cast Thalia, Guardian of Thraben; action:cast Strict Proctor; action:cast Voice of Victory
Use when: a hate card is legal and opponent public information shows spell-chain, triggered-ability, or instant-speed interaction pressure.
Avoid when: the hate card blocks this turn's necessary Chord of Calling, Green Sun's Zenith, or multi-spell engine setup more than it slows the opponent.
Instructions: Deploy hate before the opponent's critical turn when it does not strand the current hand. Treat symmetrical restrictions as temporary tempo tools, not automatic plays.
Pilot skill floor: medium
No-API allowed: no
Light-model allowed: yes
### Policy: Combat With Engine Bodies
Priority: Medium
Decision families: combat
Cards: Young Wolf; Badgermole Cub; Birds of Paradise; Delighted Halfling; Yawgmoth, Thran Physician; A-Blood Artist
Use when: combat choices involve creatures needed for mana, convoke, sacrifice, or combo.
Avoid when: exactly one legal no-attack or no-block action is forced by the engine.
Instructions: Preserve mana creatures and Yawgmoth, Thran Physician unless attacking or blocking changes lethal math, protects life total, or converts into sacrifice value. Trade expendable creatures when death triggers, counters, or A-Blood Artist make the exchange favorable by visible state.
Pilot skill floor: medium
No-API allowed: no
Light-model allowed: yes
### Policy: Survival Block Gate
Priority: High
Decision families: combat; interaction
Cards: Young Wolf; Badgermole Cub; Prosperous Innkeeper; Rope Line Attendant; Endurance; Accursed Marauder
Phase windows: declare blockers, before combat damage
Use when: visible attackers threaten lethal or a short clock.
Avoid when: a legal instant-speed interaction line clearly prevents more damage without losing key board material.
Instructions: Block to survive before preserving combo texture. Use resilient or replaceable bodies first, then utility creatures, and protect Yawgmoth, Thran Physician unless no other block prevents the loss.
Use when: visible graveyard cards enable opponent recursion, combo, delve, escape, reanimation, or flashback.
Avoid when: graveyard action is low impact and board survival is under immediate pressure.
Instructions: Use Endurance for high-impact graveyard resets or surprise blocks, Deathrite Shaman for targeted incremental pressure, and Agatha's Soul Cauldron when exiling a card also advances this deck's board.
Pilot skill floor: medium
No-API allowed: no
Light-model allowed: yes
### Policy: Sideboard Plan Selection
Priority: High
Decision families: sideboard
Cards: Deafening Silence; Endurance; Accursed Marauder; A-Haywire Mite; Archon of Emeria; Chittering Illuminator; Hapatra, Vizier of Poisons; Juggernaut Peddler; Outland Liberator; Strict Proctor; Sylvan Safekeeper; Thalia, Guardian of Thraben; Voice of Victory
Use when: choosing or validating sideboard configuration.
Avoid when: no opponent archetype signals or exact sideboard legality is unavailable.
Instructions: Add hate that attacks the opponent's public axis while preserving enough creatures, tutors, and Yawgmoth, Thran Physician access. Do not dilute the engine with one-of answers unless they answer a visible card class or matchup speed problem.
Use when: protecting Yawgmoth, Thran Physician, Agatha's Soul Cauldron pressure, or a tutor line is more important than immediate speed.
Avoid when: sacrificing lands or spending mana prevents the current lethal or survival line.
Instructions: Commit protection before engine exposure against removal-heavy public information. Use land-sacrifice protection only when the protected permanent is decisive or losing it collapses the turn.
Pilot skill floor: high
No-API allowed: no
Light-model allowed: yes
### Policy: Deterministic Single Legal Pass
Priority: Low
Decision families: priority
Cards: none
Phase windows: priority windows with no board-changing legal action
Runtime cues: action:pass priority
Use when: the only visible legal action text is pass priority.
Avoid when: any legal action besides pass priority is present.
Instructions: Pass priority when the rules engine exposes no alternative legal action.
