# Strategy Specifications
## Deck Name And Archetype

- Identity: Jund Sacrifice is a Pioneer 60-card main deck with a 15-card sideboard built as a hybrid midrange-combo sacrifice shell. Treat it as a board-centric attrition deck first, with combo-like damage bursts from Cauldron Familiar, Witch's Oven, Mayhem Devil, Scavenger's Talent, and Ygra, Eater of All when the visible board and legal actions support committing to the engine.

- Validation: The registered deck passes the active Pioneer validation contract with 60 main-deck cards and 15 sideboard cards. Use only the registered main-deck names as legal `Cut:` candidates and only the registered sideboard names as legal `Side in:` candidates when executing sideboard plans.

- Registered format: Pioneer. The pilot must respect Pioneer legality, the rules-engine legal action list, and the current game zone state over any strategic shortcut. If Veles or the rules engine reports no legal sacrifice, target, attack, block, cast, channel, discard, or sideboard action, do not infer one from archetype logic.

- Archetype tags: Use `midrange`, `combo`, `sacrifice`, `artifact`, and `food` as the active strategy tags. The duplicate supplied tag set should be normalized to those five tactical tags, with `midrange` and `combo` both retained because this deck can win by incremental removal and card advantage or by concentrated sacrifice damage.

- Stock status: Treat this as a hybrid or customized Jund Sacrifice list rather than a fully stock baseline. The core familiar-oven-devil package is recognizable, but Ygra, Eater of All, Scavenger's Talent, and the Avatar-themed sideboard suite make card-text and matchup-role validation important before assuming stock Pioneer heuristics.

- Core main-deck structure: The sacrifice engine is anchored by 4 Cauldron Familiar, 4 Witch's Oven, 4 Mayhem Devil, 4 Scavenger's Talent, 4 Deadly Dispute, 4 Eyetwitch, and 4 Bloodtithe Harvester. The midrange shell is supported by 4 Fatal Push and 4 Fable of the Mirror-Breaker, with 2 Ygra, Eater of All as a high-impact engine or finisher whose exact tactical commitment should remain conditional on current card text, legal actions, and visible interaction.

- Mana identity: The deck is Jund by strategy and mana construction, with black and red as the stable base and green supplied mainly through Overgrown Tomb and likely Blazemire Verge or Blood Crypt adjacent fixing. Prioritize black and red access early because Cauldron Familiar, Witch's Oven, Bloodtithe Harvester, Fatal Push, Deadly Dispute, Mayhem Devil, and Fable of the Mirror-Breaker define the first turns.

- Mana concern: The registered lands include 3 Blazemire Verge, 4 Blightstep Pathway, 1 Den of the Bugbear, 3 Overgrown Tomb, 1 Sokenzan, Crucible of Defiance, 2 Swamp, 4 Blackcleave Cliffs, and 4 Blood Crypt. Watch for hands that have green but lack early black or red, hands that rely on creature lands or channel lands as colored setup, and hands where tapped or pain sequencing could prevent Fatal Push, Witch's Oven, or Bloodtithe Harvester from being timely.

- Role concern: Do not pilot the deck as pure combo when the visible board demands survival. Fatal Push, Bloodtithe Harvester, Mayhem Devil triggers, and sacrifice fodder should preserve life total and board parity against pressure, while Deadly Dispute, Fable of the Mirror-Breaker, Scavenger's Talent, and recursive Cauldron Familiar lines should pull ahead when the game slows.

- Legality concern: The sideboard contains The Legend of Roku, Ozai's Cruelty, Decorum Dissertation, Abandon Attachments, Origin of Metalbending, Firebending Lesson, Ruinous Waterbending, and Pest Summoning. Card text check required for these less familiar names before assigning precise battlefield, stack, lesson, or matchup functions; until verified, use only rules-engine legal action text and visible card characteristics.

- Opponent information status: No specific opponent deck is supplied for this guide batch. Apply opponent guidance only from public information, revealed cards, known match labels, logged actions, and visible board state; do not assume hidden staples, sideboard cards, commander protection, tutor, ramp, or utility cards unless Veles exposes them as known information.

## Thesis

- Assemble recursive sacrifice pressure before committing to damage bursts. This deck wants Cauldron Familiar plus Witch's Oven as the low-cost loop, Mayhem Devil as the conversion payoff, Scavenger's Talent and Deadly Dispute as resource engines, and Fable of the Mirror-Breaker or Bloodtithe Harvester as midgame stabilizers that keep the board usable while the engine scales.

- Win by turning disposable permanents into damage, cards, tokens, and inevitability. Cauldron Familiar drains and returns, Witch's Oven creates Food and sacrifice timing, Mayhem Devil converts every sacrifice into tactical damage, Deadly Dispute converts expendable material into cards and Treasure, and Ygra, Eater of All should be treated as a high-impact engine or finisher only when the rules engine confirms its current legal text and action set.

- Prioritize survival when behind and engine density when stable. Against visible pressure, Fatal Push, Bloodtithe Harvester, Mayhem Devil trigger placement, and blocks with Eyetwitch or expendable bodies are the first priority; once life total and board are stable, prioritize repeated Cauldron Familiar loops, Deadly Dispute value, Scavenger's Talent progress, and Fable of the Mirror-Breaker filtering.

- Do not pilot this as a pure all-in combo deck. The deck is not trying to ignore the opponent, race every board, or sacrifice key resources just because a sacrifice action exists; every sacrifice should either answer a visible threat, protect a card from removal, generate cards/mana, enable a known payoff, or preserve a future Cauldron Familiar/Witch's Oven loop.

- Respect legal actions over pattern memory. If Veles does not expose the relevant sacrifice, target, Food, Treasure, token, chapter, discard, channel, or attack action, do not infer it; choose among the visible legal actions and use known public information rather than hidden-card assumptions.

## Role Package

- Threats: Mayhem Devil is the main battlefield threat because it punishes both players' sacrifices and turns routine resources into removal or reach. Bloodtithe Harvester is the early body that pressures, trades, and may convert Blood or itself into interaction when legal. Fable of the Mirror-Breaker supplies a creature token, filtering, and a later threat if the saga completes. Ygra, Eater of All is a top-end threat or engine piece, but Card text check required before treating it as deterministic combo material.

- Payoffs: Cauldron Familiar is the repeatable drain payoff when Witch's Oven or other Food access is present. Mayhem Devil is the highest-leverage payoff for sacrificing permanents, especially when multiple sacrifice events can be sequenced in one turn. Scavenger's Talent is an engine payoff that should be advanced when its visible legal actions improve material, recursion, or sacrifice output. Ygra, Eater of All may amplify Food or sacrifice play patterns, but keep all Ygra lines conditional on rules-engine output.

- Engines: Witch's Oven plus Cauldron Familiar is the core recursion engine and should be preserved unless sacrificing one piece prevents lethal damage, counters removal by moving a target, or unlocks a superior visible line. Scavenger's Talent is the secondary engine that can turn repeated deaths or sacrifices into durable advantage. Fable of the Mirror-Breaker is the midrange engine that fixes weak hands and produces material for later sacrifice turns.

- Velocity: Deadly Dispute is the cleanest card-velocity spell when an expendable artifact, creature, Food, Blood, Treasure, Eyetwitch, or threatened permanent can be sacrificed legally. Fable of the Mirror-Breaker filters redundant lands, extra legends, stranded interaction, or low-impact engine duplicates when the visible game calls for action. Bloodtithe Harvester's Blood token can smooth draws when removal conversion is not needed.

- Interaction: Fatal Push is the primary efficient answer to visible creatures and should be held for threats that matter to survival, engine safety, or lethal math. Bloodtithe Harvester can become removal when legal and should be valued more highly when Fatal Push cannot answer the current threat. Mayhem Devil triggers are interaction as well as reach; aim them at creatures, planeswalkers, or opponents only according to visible board urgency and lethal pressure.

- Protection: The main deck protects itself through redundancy, sacrifice timing, and discard-filtering rather than dedicated protection spells. Sacrificing a targeted creature to Witch's Oven or Deadly Dispute can deny opposing removal value when legal, but do not sacrifice a unique engine piece if the resulting material does not improve the current or next decision frame. Thoughtseize from the sideboard can function as proactive protection against interaction after sideboarding.

- Recursion: Cauldron Familiar is the reliable recursion card when Food is available and the rules engine exposes the return action. Scavenger's Talent may provide recursion or graveyard leverage depending on its current text and level state; Card text check required for exact mode timing. Eyetwitch may replace itself or access sideboard-style material when it dies, but exact learn/lesson legality must come from Veles actions.

- Mana: Black and red are the early priorities for Cauldron Familiar, Fatal Push, Witch's Oven, Bloodtithe Harvester, Deadly Dispute, Mayhem Devil, and Fable of the Mirror-Breaker. Blackcleave Cliffs, Blood Crypt, Blightstep Pathway, Blazemire Verge, Overgrown Tomb, Swamp, Den of the Bugbear, and Sokenzan, Crucible of Defiance should be sequenced to preserve early black-red access while keeping green available for Ygra, Eater of All or Scavenger's Talent lines if required.

- Sideboard modules: Thoughtseize is the proactive disruption module. Unlicensed Hearse is the graveyard-pressure and graveyard-denial module. The Legend of Roku, Ozai's Cruelty, Decorum Dissertation, Abandon Attachments, Origin of Metalbending, Firebending Lesson, Ruinous Waterbending, and Pest Summoning require card text checks before precise tactical roles are assigned; use only legal action text and visible effects until verified.

## Primary Win Conditions

- Engine drain is the default win path when Cauldron Familiar and Witch's Oven are both active or easily assembled. Set up by keeping at least one Food source or sacrifice outlet available, then execute by sacrificing Cauldron Familiar to Witch's Oven, returning Cauldron Familiar with Food when the action is legal, and using the repeated life drain to turn stalled boards into a clock. Prioritize this line when the opponent is pressuring life totals slowly, when removal makes combat unreliable, or when your hand has Deadly Dispute, Scavenger's Talent, or Mayhem Devil to multiply each sacrifice.

- Mayhem Devil converts the sacrifice engine into removal, reach, and combat control. Set up by preserving disposable permanents from Cauldron Familiar, Witch's Oven, Bloodtithe Harvester, Deadly Dispute, Treasure, Food, Blood, Eyetwitch, and Fable of the Mirror-Breaker tokens; execute by aiming Mayhem Devil triggers first at survival-critical creatures, then at planeswalkers or the opponent when lethal or near-lethal pressure is visible. Prioritize this line when the opponent has small creatures, sacrifice permanents of their own, low life, or a board where trigger placement can both clear blockers and advance damage.

- Scavenger's Talent is a scaling engine win path, but Card text check required for exact level, trigger, and recursion choices. Set up by pairing it with repeatable deaths or sacrifices from Cauldron Familiar, Witch's Oven, Eyetwitch, Bloodtithe Harvester, and disposable tokens; execute only through Veles-exposed legal actions, favoring choices that add material, recur key permanents, or make future sacrifice turns stronger. Prioritize it when the game is stable enough to invest mana and when a longer resource fight matters more than immediate removal.

- Ygra, Eater of All is a high-impact finisher or engine amplifier only when its visible legal text and actions confirm the relevant interaction. Set up by reaching stable mana and maintaining sacrifice/food infrastructure; execute by committing Ygra, Eater of All when the opponent is low on visible pressure or when waiting risks losing the window. Prioritize it as a top-end closer, not as an assumed combo, unless Veles exposes the exact legal line.

## Secondary Win Conditions

- Fable of the Mirror-Breaker wins fair games by producing material, filtering weak resources, and eventually creating a must-answer threat if the saga completes. Use the token to pressure, trade, make mana when legal, or become sacrifice material; use filtering to exchange excess lands, redundant Witch's Oven, stranded Fatal Push, or extra legendary/top-end cards for action. Prioritize this line when the hand lacks the full Cauldron Familiar plus Witch's Oven engine or when the opponent is trading one-for-one.

- Bloodtithe Harvester is backup pressure and conditional removal. Attack when it can safely reduce the opponent's clock or force awkward blocks, but preserve it when its visible removal action is needed for a creature that Fatal Push cannot efficiently answer. Its Blood token can convert low-impact cards into new looks when the board is stable or when digging for Mayhem Devil, Witch's Oven, or Cauldron Familiar is more important than holding every card.

- Creature-land pressure closes games after resource exchanges. Den of the Bugbear should attack when activation is legal, mana is not needed for higher-impact actions, and the opponent's visible blockers or removal do not make the attack wasteful. Sokenzan, Crucible of Defiance can provide surprise bodies or sacrifice material only when Veles exposes the channel/action and the resulting board matters.

- Eyetwitch and small creatures can win by chip damage when engines are disrupted. Attack with Eyetwitch, Cauldron Familiar, Bloodtithe Harvester, Fable of the Mirror-Breaker tokens, and Mayhem Devil when blocks are favorable or when damage pushes the opponent into Mayhem Devil or Cauldron Familiar reach. Do not trade away the only engine creature if its future sacrifice value is visibly higher than the current combat damage.

## Emergency Lines

- When behind on life, stop treating drain as inevitability and stabilize first. Use Fatal Push, Bloodtithe Harvester removal, Mayhem Devil triggers, Eyetwitch blocks, and expendable tokens to reduce incoming damage before spending mana on slow engine upgrades. Cauldron Familiar recursion is valuable here because each loop changes the race while also supplying a blocker or sacrifice object.

- When behind on board, turn sacrifice triggers into removal before aiming damage at the opponent. A Mayhem Devil turn that kills two attackers is usually more important than face damage unless lethal is already visible. Preserve Witch's Oven to blank removal, create Food, and reset Cauldron Familiar only when the legal action improves the next board state.

- When behind on cards, use Deadly Dispute and Fable of the Mirror-Breaker to rebuild from expendable material. Sacrifice Eyetwitch, a token, Food, Blood, Treasure, or a creature already losing value before sacrificing Mayhem Devil, Witch's Oven, or the only Cauldron Familiar. If Scavenger's Talent offers a legal card-advantage or recursion action, take it only when it does not worsen immediate survival.

- When behind on mana, prioritize untapped black-red access and avoid expensive commitment turns that leave Fatal Push or sacrifice interaction unusable. Use Deadly Dispute Treasure, Fable of the Mirror-Breaker token mana, Blood token filtering, and land drops from Blightstep Pathway, Blackcleave Cliffs, Blood Crypt, Overgrown Tomb, Swamp, and Blazemire Verge according to visible color needs.

- When engines are removed, pivot to midrange pressure instead of waiting passively. Bloodtithe Harvester, Fable of the Mirror-Breaker, Mayhem Devil, Den of the Bugbear, and Ygra, Eater of All can win without the full Cauldron Familiar loop. When Cauldron Familiar is gone or graveyard recursion is blocked, value Witch's Oven and Deadly Dispute as sacrifice/value tools rather than as a guaranteed loop.

- When facing faster combo or an opposing lock, shorten the clock and preserve interaction for the visible payoff. Attack more aggressively with Bloodtithe Harvester, Mayhem Devil, Fable of the Mirror-Breaker tokens, and creature lands, but do not invent hidden threats; spend Fatal Push, sacrifice triggers, and discard-filtering decisions only on legal actions and public board cues.

## Resource Model

- Life is a spendable buffer, not a protected total, until the opponent shows a short clock. Use Blood Crypt and Overgrown Tomb untapped when the extra mana creates Cauldron Familiar plus Witch's Oven, Fatal Push plus engine setup, Fable of the Mirror-Breaker on curve, or Thoughtseize after sideboard. Shift from paying life to preserving life once visible attacks plus burn-like pressure can beat Cauldron Familiar drain.

- Hand size converts into board and sacrifice velocity. Deadly Dispute turns expendable permanents into cards and Treasure, Fable of the Mirror-Breaker filters redundant lands or stranded removal, and Bloodtithe Harvester's Blood token can exchange low-impact cards for engine pieces. Do not discard or sacrifice the only copy of a functional engine role unless the legal action immediately stabilizes or advances lethal pressure.

- Mana is the throttle on double-spell turns. Prioritize black and red early because Cauldron Familiar, Witch's Oven, Fatal Push, Bloodtithe Harvester, Deadly Dispute, Mayhem Devil, Fable of the Mirror-Breaker, and Thoughtseize all reward using mana on curve. Treat green access from Overgrown Tomb and Blazemire Verge as important for Scavenger's Talent and Ygra, Eater of All, but do not keep a hand that only works after drawing green unless the black-red plan is already functional.

- Board material is a renewable resource when it is disposable. Eyetwitch, Cauldron Familiar, Food, Blood, Treasure, Fable of the Mirror-Breaker tokens, and creature-land bodies can become Deadly Dispute fuel, Witch's Oven fodder, or Mayhem Devil triggers. Preserve Mayhem Devil, Witch's Oven, Scavenger's Talent, and Ygra, Eater of All over replaceable bodies unless sacrificing them is the only legal survival line.

- Graveyard access matters because Cauldron Familiar and some Scavenger's Talent lines can make the graveyard part of the engine, but Card text check required for exact Scavenger's Talent recursion choices. Respect visible graveyard hate from the opponent and your own Unlicensed Hearse after sideboard; if the graveyard is constrained, pivot toward Bloodtithe Harvester, Fable of the Mirror-Breaker, Mayhem Devil triggers, Den of the Bugbear, and Ygra, Eater of All.

- Exile is mostly a cost or denial zone for this deck unless Veles exposes a specific legal action. Do not assume exiled cards are recoverable. When sideboard cards such as Unlicensed Hearse interact with graveyards, use exile decisions to shrink opponent resources or stop visible recursion, not to chase low-impact cards while under pressure.

- Lands are both color sources and late-game actions. Den of the Bugbear is a closing resource when the board is stable and mana is unused; Sokenzan, Crucible of Defiance is a utility land only if Veles exposes its legal action and the bodies matter. Avoid spending utility-land actions when holding priority for Fatal Push, Deadly Dispute, Witch's Oven, or Mayhem Devil trigger sequencing is stronger.

- Sacrifice fodder is the deck's core currency. Spend Food, Blood, Treasure, Eyetwitch, tokens, and redundant small creatures before sacrificing engine cards. With Mayhem Devil visible, count every sacrifice from either player as potential damage allocation and aim triggers according to survival first, then planeswalkers or lethal pressure.

- Tempo is gained by making the opponent's removal and combat awkward. Witch's Oven can convert removal targets into Food, Fatal Push and Bloodtithe Harvester can remove attackers or blockers, and Deadly Dispute can punish removal when a sacrifice target is already exposed. Use these exchanges to buy time for recursive engines rather than taking low-value actions just because they are legal.

- Information is valuable after sideboard because Thoughtseize can reveal whether to commit Mayhem Devil, Fable of the Mirror-Breaker, Scavenger's Talent, or Ygra, Eater of All. Use revealed information only while it remains known from logs or visible state; never infer exact hidden cards from archetype alone.

- Sideboard bullets convert narrow resources into matchup leverage. Thoughtseize spends life and a card to disrupt noncreature plans, Unlicensed Hearse spends tempo to pressure graveyards, Pest Summoning supplies bodies if legally available, and The Legend of Roku, Ozai's Cruelty, Decorum Dissertation, Abandon Attachments, Origin of Metalbending, Firebending Lesson, and Ruinous Waterbending need Card text check required before exact tactical use.

## Mana Guide

- Keep hands that produce black and red by turn two with at least one engine or interaction line. A strong keep usually has Blackcleave Cliffs, Blood Crypt, Blightstep Pathway, Blazemire Verge, Overgrown Tomb, or Swamp plus Cauldron Familiar, Witch's Oven, Fatal Push, Bloodtithe Harvester, Deadly Dispute, or Fable of the Mirror-Breaker. Mulligan hands with only colorless utility actions, no early black source, or no castable spell before turn three unless the matchup context strongly rewards a slower hand.

- Sequence lands to unlock the first two turns before optimizing life total. Blackcleave Cliffs is best early when untapped; Blood Crypt and Overgrown Tomb should enter untapped only when the mana is needed this turn or next turn for a concrete legal line. Blightstep Pathway should choose the side that fixes the hand's missing black or red requirement; do not choose based on generic preference if current actions reveal a specific color bottleneck.

- Prioritize early black for Cauldron Familiar, Fatal Push, Deadly Dispute, Eyetwitch, Thoughtseize, and many sacrifice turns. Prioritize early red for Bloodtithe Harvester, Mayhem Devil, and Fable of the Mirror-Breaker. Prioritize green only after black-red function is established, unless Scavenger's Talent or Ygra, Eater of All is the hand's only meaningful plan and the matchup gives time.

- Play lands before drawing when the current turn already needs exact mana for a known legal action. Make the land drop first to cast Fable of the Mirror-Breaker, Mayhem Devil, Bloodtithe Harvester plus Witch's Oven, or Fatal Push plus Deadly Dispute when the hand and board already define the line. Wait until after Deadly Dispute, Blood token filtering, or Fable of the Mirror-Breaker filtering when no current land is needed and drawing could change which land or Pathway side is correct.

- Preserve untapped mana when interaction or sacrifice protection matters. Leaving black for Fatal Push, Deadly Dispute, or Thoughtseize can be better than spending mana on Scavenger's Talent levels or utility-land actions. Leaving Witch's Oven activation available can protect Cauldron Familiar or turn removal into Food, especially with Mayhem Devil on board.

- Use Treasure from Deadly Dispute as a bridge, not as a permanent fix. Treasure can enable double-spell turns, Ygra, Eater of All, Fable of the Mirror-Breaker plus interaction, or sideboard bullets, but sacrificing Treasure also changes Mayhem Devil math when Mayhem Devil is visible. Count Treasure as both mana and a sacrifice trigger before choosing payment order.

- Treat Den of the Bugbear and Sokenzan, Crucible of Defiance as lands first until the game reaches a mana surplus. Activate or channel only when the legal action improves the current combat, creates sacrifice material, or closes the game without exposing a stronger spell line. If mana is tight, use them to cast spells instead of chasing marginal damage.

- Avoid tapped-land mistakes by planning the next turn's color pair. Blood Crypt, Overgrown Tomb, Blackcleave Cliffs timing, Blazemire Verge access, and Blightstep Pathway choices should be evaluated against the next visible spell sequence, not only the current turn. A turn-one tapped shock land is acceptable when no one-mana play exists; it is costly when it delays Fatal Push, Cauldron Familiar, Witch's Oven, Eyetwitch, or Thoughtseize.

## Mulligan Guide

- Strong keep: Keep two or three lands with black and red access plus one early engine and one interaction/value piece. Examples include Blackcleave Cliffs plus Blood Crypt with Cauldron Familiar, Witch's Oven, Mayhem Devil, and Fatal Push; or Blightstep Pathway plus Overgrown Tomb with Eyetwitch, Deadly Dispute, Bloodtithe Harvester, and Fable of the Mirror-Breaker.

- Medium keep: Keep functional hands that have mana, pressure, and a turn-three plan but lack the full sacrifice loop. A hand with Bloodtithe Harvester, Fatal Push, Fable of the Mirror-Breaker, and three lands is acceptable against creature decks; a hand with Eyetwitch, Deadly Dispute, Scavenger's Talent, and lands is acceptable when the matchup is not punishing a slower setup. Card text check required for exact Scavenger's Talent level timing.

- Risky keep: Keep one-land hands only on the draw with Blackcleave Cliffs, Blood Crypt, Blightstep Pathway, or Swamp plus multiple one-mana legal plays and a clear second-land payoff. Cauldron Familiar, Witch's Oven, Fatal Push, and Eyetwitch can justify risk; Mayhem Devil, Fable of the Mirror-Breaker, Ygra, Eater of All, and Deadly Dispute without fodder do not.

- Automatic ship: Mulligan hands with no land, one land and no one-mana play, all lands and no engine or interaction, no black source, or no spell before turn three. Ship hands that rely on Den of the Bugbear or Sokenzan, Crucible of Defiance as the only meaningful early action unless Veles shows a legal line that stabilizes.

- Matchup-dependent keep: Against fast creature pressure, value Fatal Push, Cauldron Familiar plus Witch's Oven, Bloodtithe Harvester, and Eyetwitch more than slow Scavenger's Talent or Ygra, Eater of All. Against slower interaction or combo, value Thoughtseize after sideboard, Fable of the Mirror-Breaker, Mayhem Devil, Deadly Dispute, and redundant engines more than isolated Fatal Push.

- Play/draw adjustment: On the play, keep hands that deploy a turn-one permanent and curve into Bloodtithe Harvester, Mayhem Devil, or Fable of the Mirror-Breaker. On the draw, tolerate slightly slower two-land hands if Fatal Push or Bloodtithe Harvester can answer the first threat and Deadly Dispute or Fable of the Mirror-Breaker can recover cards.

- Trap hand: Do not keep Cauldron Familiar without Witch's Oven, Deadly Dispute, Scavenger's Talent, or another visible sacrifice payoff just because the card is cheap. Do not keep Mayhem Devil-heavy hands without early lands and sacrifice material. Do not keep Ygra, Eater of All as the only payoff unless the hand already casts early spells and reaches the required mana.

## Turn Arc

- Turn 1: Prefer Blackcleave Cliffs, Blightstep Pathway, Blood Crypt, Swamp, or Blazemire Verge into Cauldron Familiar, Witch's Oven, Eyetwitch, Fatal Push hold-up, or Thoughtseize after sideboard when legal. Lead Witch's Oven before Cauldron Familiar when removal protection and future loop setup matter; lead Cauldron Familiar when pressure, Deadly Dispute fodder, or immediate life-total movement matters.

- Turn 1 deviation: Shock Blood Crypt or Overgrown Tomb only when the current or next turn requires untapped mana for a concrete legal action. If no one-mana action exists, play the land that best unlocks turn-two Bloodtithe Harvester, Deadly Dispute, or Scavenger's Talent without losing unnecessary life.

- Turn 2: Prefer Bloodtithe Harvester against creature pressure, Cauldron Familiar plus Witch's Oven when both are available, or Eyetwitch plus Deadly Dispute when the sacrifice target and payoff are already legal. Hold Fatal Push when the opponent's visible threat or likely next attack matters more than adding a low-impact permanent.

- Turn 2 deviation: Use Deadly Dispute defensively when the opponent targets a creature or when sacrificing Eyetwitch, Cauldron Familiar, Food, Blood, or Treasure produces a stronger turn-three line. Avoid sacrificing the only engine piece if it leaves Mayhem Devil, Scavenger's Talent, or Witch's Oven unsupported.

- Turn 3: Prefer Mayhem Devil when sacrifice material is already visible or when both players are likely to sacrifice permanents soon. Prefer Fable of the Mirror-Breaker when the hand needs filtering, mana development, or a sticky threat through removal. Prefer Fatal Push plus a two-mana setup spell when survival is the priority.

- Turn 3 deviation: Delay Mayhem Devil into open interaction if the hand can first create Food, Blood, Treasure, or disposable bodies. Commit Scavenger's Talent when the legal action advances the engine and does not leave the board undefended; exact activation and recursion choices require visible legal actions and card text confirmation.

- Turns 4-5: Convert setup into damage, cards, and board control. With Mayhem Devil visible, count every Witch's Oven activation, Deadly Dispute cost, Blood token use, Treasure sacrifice, and opponent sacrifice as damage routing. Aim triggers at lethal or planeswalkers only after killing must-answer creatures and preserving your own survival.

- Turns 4-5 deviation: Cast Ygra, Eater of All only when Veles shows the legal action, mana is available, and the board or matchup rewards a large commitment. If the opponent is threatening lethal, prioritize Fatal Push, Bloodtithe Harvester removal actions, Witch's Oven protection, and sacrificial blockers over a tap-out payoff.

- Late game: Turn redundant permanents into resources and close through recursive pressure. Den of the Bugbear, Sokenzan, Crucible of Defiance, Fable of the Mirror-Breaker, Scavenger's Talent, Cauldron Familiar loops, and Mayhem Devil triggers are the main ways to turn stalled boards into wins.

- Late-game deviation: Do not spend mana on utility-land actions or marginal filtering when holding interaction prevents lethal, protects Mayhem Devil, or enables a decisive Deadly Dispute. Respect visible graveyard hate and exile effects; if recursion is blocked, win with battlefield pressure, tokens, Bloodtithe Harvester, Fable of the Mirror-Breaker, Den of the Bugbear, and Ygra, Eater of All.

## Card Roles

- Cauldron Familiar: Use Cauldron Familiar as the cheap recursive body that turns sacrifice outlets into life-total pressure, blockers, and repeatable material. Cast it early when Witch's Oven, Deadly Dispute, Scavenger's Talent, or Mayhem Devil is already present or likely to matter soon. Hold it only when the hand has a better turn-one legal action, when exposing it to exile reduces the engine, or when sequencing Witch's Oven first protects the loop. With Witch's Oven, prioritize the loop when it changes combat math, drains toward lethal, turns on Mayhem Devil, or creates Food for later turns. Do not treat Cauldron Familiar as a normal attacker into profitable blocks unless the damage matters or its death enables an immediate legal recursion/sacrifice chain.

- Witch's Oven: Use Witch's Oven as the deck's most important repeatable sacrifice outlet and as protection against removal, combat damage, and exile-adjacent pressure when the legal action is available. Deploy it early when the hand contains Cauldron Familiar, Eyetwitch, Bloodtithe Harvester, Mayhem Devil, Scavenger's Talent, or Deadly Dispute. Preserve untapped Witch's Oven when a creature may be targeted, when a blocker can be converted after damage assignment timing is clear, or when Mayhem Devil damage will answer a visible threat. Avoid sacrificing a creature before blocks or priority windows are fully useful unless the Food, trigger, or protection is immediately relevant.

- Mayhem Devil: Use Mayhem Devil as the primary battlefield-control and reach payoff for every sacrifice by either player. Cast it when there is visible sacrifice material or when the opponent is likely to sacrifice permanents soon; delay it when a slower setup turn creates Food, Blood, Treasure, disposable creatures, or removal protection. Route Mayhem Devil triggers first to survival targets, then to blockers or planeswalkers, then to the opponent when a race or lethal line is visible. Do not waste triggers on face damage while a creature threatens lethal, carries key pressure, or blocks the sacrifice engine from attacking. In mirrors or sacrifice-heavy matchups, Mayhem Devil is often the card that changes every small exchange into removal.

- Deadly Dispute: Use Deadly Dispute as card velocity, mana smoothing through Treasure, and a way to turn expendable objects into advantage at instant speed. Prefer sacrificing Eyetwitch, Cauldron Familiar with recursion available, Food, Blood, Treasure when mana math permits, a creature being removed, or a token that has already served its combat role. Hold Deadly Dispute when the only sacrifice is Mayhem Devil, Ygra, Eater of All, Fable of the Mirror-Breaker pressure, or the only engine piece keeping the hand functional. Cast it proactively only when the extra cards or Treasure unlock the next turn; otherwise preserve it for removal response, combat conversion, or end-step reload.

- Bloodtithe Harvester: Use Bloodtithe Harvester as the flexible bridge between early pressure, Blood token setup, and creature removal. Cast it early against creature decks because it blocks, pressures, and leaves material even if removed. Use its removal ability when the target's size is in range by visible rules output and the target matters more than keeping the body; do not cash it in just because a legal action exists. The Blood token is not free: spend it when filtering improves a poor hand, enables Mayhem Devil damage, fuels Deadly Dispute, or supports Ygra, Eater of All only if card text and board state make that interaction legal. Against control or combo, Bloodtithe Harvester often pressures life totals while fixing clunky draws.

- Eyetwitch: Use Eyetwitch as early board glue, sacrifice fodder, and a deterrent against small attackers. Cast it early when Deadly Dispute, Witch's Oven, Scavenger's Talent, or Mayhem Devil can exploit its death. Its exact death search options depend on sideboard/Lesson legality and Veles rules-engine output; Card text check required for current legal selection behavior in Pioneer with this registered sideboard. Block with Eyetwitch when it saves meaningful life, trades with an attacker, or creates a death trigger through a sacrifice outlet. Do not preserve it as a low-power attacker when sacrificing it generates cards, Treasure, Food, damage, or a legal lesson-like option.

- Fatal Push: Use Fatal Push as the efficient answer that buys time for the sacrifice engine to take over. Hold it for creatures that threaten fast damage, combo function, snowballing value, or blocks that prevent lethal pressure. Sacrifice permanents deliberately to enable revolt only when Veles shows the relevant legal result and the target justifies the resource cost. Avoid firing Fatal Push on a low-impact creature if Witch's Oven, Bloodtithe Harvester, Mayhem Devil triggers, or combat can handle it. Against slower decks, Fatal Push is still useful for protecting attacks and clearing utility creatures, but it should not displace engine deployment unless the visible board demands it.

- Fable of the Mirror-Breaker: Use Fable of the Mirror-Breaker as the main midgame stabilizer, hand filter, token pressure, and long-game value engine. Cast it on curve when survival is not immediately at risk, especially in hands with excess lands, duplicate legends, dead Fatal Push, or missing engine pieces. The token can pressure, trade, or create Treasure for Mayhem Devil and larger follow-up turns; do not attack it into obvious bad trades unless the Treasure or damage matters. Use the discard/filter chapter to convert redundant lands, extra Witch's Oven, excess Cauldron Familiar, or matchup-poor removal into engine access. Preserve transformed value only when doing so beats spending mana on immediate survival.

- Scavenger's Talent: Use Scavenger's Talent as an engine enchantment that rewards sacrifice/token death patterns, but defer exact level and trigger choices to Veles because Card text check required for current Oracle text and implementation details. Cast it when the board already has expendable material or when the hand is built to produce Food, Blood, Treasure, or disposable creatures. Do not spend a turn leveling or activating it while facing lethal pressure unless the legal action immediately stabilizes, recurs a key permanent, or creates a decisive drain/value line. It is strongest in grindy games where repeated small exchanges become a resource engine and weakest when the opponent demands immediate removal.

- Ygra, Eater of All: Use Ygra, Eater of All as a high-impact payoff that can dominate sacrifice-heavy boards, but require a card text check before assuming exact static abilities, counters, ward, or Food interactions. Cast it when mana is available, the opponent cannot punish a tap-out line from visible information, and existing Food/sacrifice material can convert it into pressure or resilience. Hold it when Fatal Push, Bloodtithe Harvester removal, or Witch's Oven protection is needed to survive the next combat. Do not keep or sequence around Ygra, Eater of All as the only plan; it is a payoff for a functional early engine, not a substitute for one.

- Blackcleave Cliffs: Use Blackcleave Cliffs as the cleanest early untapped source for one- and two-mana black/red development. Lead it when it enables Cauldron Familiar, Witch's Oven, Eyetwitch, Fatal Push, Bloodtithe Harvester, Deadly Dispute, or Mayhem Devil without life loss. Preserve shock lands when Blackcleave Cliffs already supplies the required colors.

- Blood Crypt and Overgrown Tomb: Use Blood Crypt and Overgrown Tomb as color-fixing lands whose life cost must be tied to a concrete legal action. Shock only to cast or hold a spell on time, especially Fatal Push, Thoughtseize after sideboard, Bloodtithe Harvester, Deadly Dispute, Scavenger's Talent, Mayhem Devil, or Fable of the Mirror-Breaker. Against aggressive decks, tapped shock lands are acceptable when the turn has no urgent one-mana action.

- Blightstep Pathway: Use Blightstep Pathway to choose the color that makes the next two turns functional, not just the current spell. Choose black when the hand needs Cauldron Familiar, Eyetwitch, Fatal Push, Deadly Dispute, or Scavenger's Talent; choose red when Bloodtithe Harvester, Mayhem Devil, Fable of the Mirror-Breaker, or Den of the Bugbear pressure is the bottleneck. Recheck visible hand and legal actions before locking the side.

- Blazemire Verge: Use Blazemire Verge as a fixing land only according to Veles legal mana output because Card text check required for its exact condition and color production. Sequence it to support early black/red spells when legal, but do not assume it casts every spell in a vacuum.

- Swamp: Use Swamp to protect life total and guarantee black early. Lead Swamp when the hand needs Fatal Push, Cauldron Familiar, Eyetwitch, or Deadly Dispute and red can wait. Avoid Swamp-heavy sequencing that strands Mayhem Devil or Fable of the Mirror-Breaker.

- Den of the Bugbear: Use Den of the Bugbear as a late-game threat, not an early color plan. Play it early only when entering tapped does not break the curve or when other lands cover black. Activate it when pressure matters and holding interaction is not required for survival.

- Sokenzan, Crucible of Defiance: Use Sokenzan, Crucible of Defiance as a red source first and a late channel-style threat only when Veles shows the legal action. The token mode is best when extra bodies enable attacks, blocks, sacrifice material, or Mayhem Devil pressure; do not spend it while mana must remain open for Fatal Push, Deadly Dispute, or Witch's Oven lines.

## Interaction Priorities

- Remove engines before rate creatures: Point Fatal Push, Bloodtithe Harvester Blood-token removal, and Mayhem Devil damage at creatures or permanents that create recurring cards, mana, sacrifice material, or combo progress before spending them on ordinary attackers. Kill the card that changes future legal-action quality, not the creature that merely deals the next two damage, unless the life total is already under immediate pressure.

- Preserve sacrifice interaction when revolt or death triggers matter: Use Witch's Oven, Deadly Dispute, Cauldron Familiar, Eyetwitch, and disposable tokens to turn removal turns into revolt, Food, cards, Treasure, Mayhem Devil damage, or Scavenger's Talent progress. Do not sacrifice a real engine piece just to enable Fatal Push unless the target is a visible must-answer threat or the exchange prevents lethal pressure.

- Prioritize Mayhem Devil as both removal and reach: Once Mayhem Devil is on board, every Food, Blood, Treasure, creature death, and Witch's Oven activation can become tactical damage. Aim triggers first at opposing creatures that block the engine, pressure the life total, or enable combo; aim at the opponent only when board control is already secure, lethal math is visible, or a fragile creature cannot be killed profitably.

- Use Bloodtithe Harvester as delayed removal before expendable pressure: Keep Bloodtithe Harvester untapped and available when its Blood-based removal can answer a larger creature after setup. Attack with it when the opponent cannot punish the tap, when the Blood token is not needed for removal, or when damage advances a Mayhem Devil or Cauldron Familiar clock.

- Discard first when Thoughtseize is legal after sideboard: Take the visible card that breaks the sacrifice engine, sweeps Mayhem Devil and token boards, races through Cauldron Familiar life gain, or stops the next planned engine turn. Against combo, take the enabler or payoff that makes the visible hand functional. Against control, take the clean answer to Fable of the Mirror-Breaker, Ygra, Eater of All, Mayhem Devil, or Witch's Oven if the rest of the hand already develops.

- Exile graveyards only when the target matters: Use Unlicensed Hearse on cards that visibly fuel recursion, escape, delve, reanimation, flashback-like lines, or graveyard-count payoffs. Do not spend early mana exiling random cards while behind on battlefield unless the graveyard action is the opponent's fastest path to winning.

- Treat Abandon Attachments, Ozai's Cruelty, Ruinous Waterbending, Firebending Lesson, Origin of Metalbending, Decorum Dissertation, The Legend of Roku, and Pest Summoning as text-dependent sideboard actions: Card text check required. If Veles exposes removal, bounce, token, Lesson, or modal legal actions from these cards, choose them only when their visible text answers the current threat, stabilizes combat, or advances a locked sideboard plan.

- Ignore low-impact bodies when the engine can absorb them: Small attackers that are blanked by Eyetwitch, Cauldron Familiar loops, Food life, or token chump blocks are lower priority than cards that exile graveyards, shut off sacrifice, remove Witch's Oven, or outscale Mayhem Devil. Let expendable creatures trade before spending Fatal Push on something that does not change the race.

- Bait with redundant engines before committing payoffs: Present extra Witch's Oven, Cauldron Familiar, Eyetwitch, or Fable of the Mirror-Breaker before exposing Mayhem Devil or Ygra, Eater of All when the opponent is representing open interaction. Commit the payoff first only when the visible board demands immediate damage, blocks, or pressure.

## Combat And Trading Rules

- Preserve engine permanents over chip damage: Do not attack Mayhem Devil, Bloodtithe Harvester, or a transformed Fable of the Mirror-Breaker body into trades unless the trade unlocks lethal, removes a key blocker, or produces enough sacrifice damage to replace the lost engine. Cauldron Familiar and Eyetwitch are the preferred attackers or blockers when their deaths are replaceable or beneficial.

- Block early against aggression with expendable creatures: Use Eyetwitch, Cauldron Familiar, tokens from Fable of the Mirror-Breaker, Sokenzan, Crucible of Defiance tokens, Pest Summoning tokens, and Food-backed lines to protect life total. At 10 or less life against a creature deck, prefer stabilizing blocks and removal over speculative attacks unless the crack-back is clearly survivable.

- Convert bad blocks into sacrifice value: If a creature is going to die in combat, sacrifice it to Witch's Oven or Deadly Dispute when Veles shows the legal action and the resulting Food, cards, Treasure, Mayhem Devil damage, Scavenger's Talent progress, or Eyetwitch death value improves the turn. Do not sacrifice a blocker before damage if keeping it in combat would absorb more damage and survival is the priority.

- Attack when the opponent must respect repeatable drain: Cauldron Familiar loops, Mayhem Devil triggers, Den of the Bugbear, and Fable of the Mirror-Breaker pressure let small attacks matter. Send creatures when blocks are unattractive for the opponent or when a post-combat sacrifice line punishes any trade.

- Keep Bloodtithe Harvester back when removal matters: A tapped Bloodtithe Harvester cannot serve as visible removal if its ability requires tapping or sacrificing under current rules-engine text. Attack only when the removal mode is unavailable, unnecessary, or weaker than the damage and Treasure/Blood sequencing offered by the turn.

- Treat Ygra, Eater of All as a commitment combat pivot: Card text check required before assuming exact size, ward, Food interactions, or growth. Once it is a visible combat-dominating body, protect it from avoidable double blocks and removal windows unless forcing trades immediately wins the board.

- Change combat posture by archetype: Against aggro, trade down, preserve life, and let Cauldron Familiar plus Food turn time into inevitability. Against control, attack with redundant creatures and creature lands to tax removal while holding key engines. Against combo, pressure life totals faster and trade less unless the blocker is also a combo enabler. Against midrange, force exchanges only when Mayhem Devil or Scavenger's Talent converts them into extra resources.

## Selection And Tutor Rules

- Treat this deck as pseudo-selection, not true tutoring: The main deck has no reliable named-card tutor, so select through Blood token rummage from Bloodtithe Harvester, chapter-two discard from Fable of the Mirror-Breaker, Deadly Dispute draws, Eyetwitch learn choices, and Scavenger's Talent recursion or milling if Veles exposes those actions. Do not assume a specific library card is available unless the rules engine reveals it.

- Spend discard-and-draw effects to fix function first: With Bloodtithe Harvester Blood tokens or Fable of the Mirror-Breaker chapter-two choices, discard excess lands, duplicate legendary cards, redundant Witch's Oven without Cauldron Familiar, or matchup-weak removal before discarding engine pieces. Keep at least one clean source of sacrifice, payoff, and removal when possible.

- Use Deadly Dispute as a selection burst when the sacrifice is already profitable: Sacrifice Blood, Food, Treasure, Cauldron Familiar, Eyetwitch, expendable tokens, or a creature facing removal before sacrificing Mayhem Devil, Ygra, Eater of All, or the only Bloodtithe Harvester. The immediate cards and Treasure are strongest when they unlock the same turn's land drop, Fatal Push, Witch's Oven, Mayhem Devil, or follow-up engine deployment.

- Sequence land drops after visible draw when mana is not needed first: If Blood token activation, Deadly Dispute, or Fable of the Mirror-Breaker can reveal or draw into a better land before the land drop, delay playing a land unless current mana is required to cast the draw spell or protect against missing a legal action. Make the land drop first only when untapped mana is needed immediately for Fatal Push, Deadly Dispute, Witch's Oven, Thoughtseize, or a sideboard card.

- Choose Eyetwitch learn outcomes by role and visible need: If Veles exposes Pest Summoning or another legal Lesson choice, select the card that stabilizes the board, supplies sacrifice bodies, answers the current permanent, or supports the next turn's mana curve. Card text check required for Firebending Lesson, Ozai's Cruelty, Decorum Dissertation, Abandon Attachments, Origin of Metalbending, Ruinous Waterbending, and The Legend of Roku before treating any as a specific effect.

- Use Scavenger's Talent selection only after checking text and level state: Card text check required for exact level abilities and graveyard-return permissions. When a legal recursion or graveyard selection prompt appears, favor the missing engine piece among Witch's Oven, Cauldron Familiar, Mayhem Devil, Bloodtithe Harvester, Deadly Dispute, or Fable of the Mirror-Breaker over a generic body unless survival requires a blocker.

## Priority And Stack Rules

- Hold priority actions for visible value or survival: Use Fatal Push, Bloodtithe Harvester removal, Deadly Dispute, Witch's Oven, Cauldron Familiar return, Blood activation, Food sacrifice, and sideboard instants only when Veles shows legal actions and the board state justifies them. Passing is correct when no spell changes combat, protects an engine, stops a combo, or improves mana use.

- Respond to removal by converting the target into resources: If the opponent targets Cauldron Familiar, Eyetwitch, a token, Bloodtithe Harvester, or another expendable creature, sacrifice it to Witch's Oven or Deadly Dispute when legal and when losing combat damage absorption is acceptable. Do not sacrifice Mayhem Devil or Ygra, Eater of All just to gain minor value unless the removal would kill it anyway and no protection line exists.

- Stack Mayhem Devil triggers with intent: Aim visible triggers at creatures, planeswalkers, or the opponent according to the current race, not by habit. Kill one-toughness engines and blockers before sending damage upstairs; point at the opponent when lethal or near-lethal drain is visible.

- Use Witch's Oven at the latest useful window: Sacrifice Cauldron Familiar or a doomed creature after blocks are declared when damage prevention is not needed, or before exile/bounce removal resolves when the creature would otherwise leave without death value. Avoid early sacrifices that remove a blocker before it can reduce damage.

- Return Cauldron Familiar when the Food cost advances the turn: Bring it back to drain, block, enable Mayhem Devil, pressure control, or rebuild after removal. Keep Food available instead when life gain, Deadly Dispute fodder, Scavenger's Talent progress, or future Witch's Oven loops matter more than one immediate drain.

- Fire Fatal Push in response windows that preserve tempo: Kill attackers before combat damage, combo creatures before their activation or attack matters, and blockers before declaring attacks when that opens damage. Enable revolt with Witch's Oven, Deadly Dispute, Food, Blood, Treasure, or creature deaths only when the larger target is worth the resource.

- Treat optional payments and sideboard stack actions as text-dependent: Pay costs, choose modes, or cast Abandon Attachments, Ozai's Cruelty, Ruinous Waterbending, Firebending Lesson, Origin of Metalbending, Decorum Dissertation, The Legend of Roku, and Pest Summoning only from visible legal text. Card text check required before assuming removal, protection, bounce, token creation, or card advantage.

- Respect graveyard timing with Unlicensed Hearse: Activate it before the opponent can use a visible graveyard card, not after the payoff has already resolved. If no graveyard card currently matters, spend mana on board development instead of low-impact exiling.

## Sideboard Map

- Sideboard from role pressure, not card-name habit: Add Thoughtseize against combo, control, planeswalker-heavy midrange, sweepers, and any opponent whose best card matters more than battlefield tempo. Reduce main-deck emphasis on Fatal Push only when the opponent shows few legal creature targets; keep Fatal Push against creature combo, aggressive decks, and any matchup where revolt-enabled removal answers key threats.

- Use Unlicensed Hearse as the confirmed graveyard package: Add Unlicensed Hearse against graveyard recursion, delve-style threats, flashback, reanimation, escape, or any opponent whose public graveyard is a resource. It is bad when the opponent’s graveyard is only incidental and the matchup is decided by battlefield tempo before Hearse can matter. Role change: against creature decks with graveyard payoffs, treat it as interaction first and a later attacker second; against control, treat it as slow pressure only if graveyard denial has a target.

- Treat Thoughtseize as the clean proactive disruption package: Add Thoughtseize when the opponent can assemble a combo, resolve a sweeper, protect a key threat, or present noncreature engines Fatal Push cannot touch. It is bad when life total is under immediate pressure from small attackers and the hand already has removal plus sacrifice engines. Role change: on the play it can clear the way for Witch's Oven, Scavenger's Talent, Mayhem Devil, or Fable of the Mirror-Breaker; on the draw against aggro it must take the card that prevents stabilization, not the most expensive card by default.

- Treat Pest Summoning as the safest Lesson-style body when Eyetwitch learns and bodies matter: Card text check required, but if Veles confirms Pest Summoning creates expendable creatures, choose or add it when sacrifice fodder, blockers, Scavenger's Talent progress, or Deadly Dispute material is more important than narrow interaction. It is bad when the matchup is about answering one spell immediately or when tokens do not block profitably.

- Treat Firebending Lesson as text-dependent reach or removal only after rules output confirms legal text: Card text check required. Add or learn Firebending Lesson when its visible legal effect kills a relevant creature, pressures a planeswalker, or creates lethal reach without sacrificing engine integrity. It is bad when mana is constrained, when the effect is too small for the visible threat, or when spending a turn on it delays Witch's Oven plus Cauldron Familiar or Mayhem Devil.

- Treat Ozai's Cruelty as text-dependent disruption or removal: Card text check required. Add it only when its visible text interacts with the opponent’s primary axis better than main-deck Fatal Push, Bloodtithe Harvester, Thoughtseize, or Mayhem Devil triggers. It is bad when the card’s confirmed mode is narrow, slow, or overlaps with already sufficient interaction.

- Treat Ruinous Waterbending as text-dependent answer technology: Card text check required. Add it when Veles confirms it answers a permanent, stack object, combat state, or threat class that the main deck otherwise struggles to manage. It is bad when its confirmed target class is absent, when it cannot be cast on curve, or when the matchup rewards proactive engine density.

- Treat Abandon Attachments as narrow text-dependent utility: Card text check required. Add it when the opponent’s revealed or known plan depends on Auras, Equipment, counters, attachments, or a permanent type the card explicitly names. It is bad when the opponent has not shown those objects and the matchup rewards pressure, sacrifice loops, or discard instead.

- Treat Origin of Metalbending as text-dependent artifact or engine support: Card text check required. Add it when its visible legal text improves artifact density, answers artifacts, creates material for sacrifice, or breaks a board stall. It is bad when the matchup punishes noninteractive setup or when the main deck already has enough Witch's Oven, Food, Blood, and Treasure material.

- Treat Decorum Dissertation as text-dependent value or interaction: Card text check required. Add it when the confirmed text creates card advantage, disrupts the opponent’s key permanent type, or stabilizes a board state better than a low-impact main-deck draw. It is bad when the matchup is too fast for speculative value or when the card does not affect the current axis of attack.

- Treat The Legend of Roku as a high-variance text-dependent role card: Card text check required. Add The Legend of Roku only when its confirmed chapters or abilities are relevant to the matchup’s public threats, engine development, or closing speed. It is bad when the opponent can ignore a slow saga-style permanent, when mana is pressured, or when the deck needs instant-speed answers.

Balanced anti-combo/control disruption plan
Side in: 4 Thoughtseize; 2 Unlicensed Hearse
Cut: 4 Fatal Push; 1 Witch's Oven; 1 Deadly Dispute

- Use this exact plan when the opponent has few creature targets, relies on hand-contained combo or sweepers, and uses the graveyard enough for Unlicensed Hearse to matter. Keep Cauldron Familiar, Scavenger's Talent, Mayhem Devil, Fable of the Mirror-Breaker, and Ygra, Eater of All as pressure and inevitability; Thoughtseize should protect the engine or take the card that wins before the sacrifice loop matters.

Balanced creature-pressure stabilization plan
Side in: 1 Pest Summoning; 1 Firebending Lesson; 1 Ozai's Cruelty; 1 Ruinous Waterbending
Cut: 2 Deadly Dispute; 1 Scavenger's Talent; 1 Ygra, Eater of All

- Use this exact plan only after card text checks confirm the four sideboard cards contribute bodies, removal, tempo, or stabilization against visible creature pressure. Keep all Fatal Push, Bloodtithe Harvester, Witch's Oven, Cauldron Familiar, and Mayhem Devil because the deck wins creature matchups by trading repeatedly while converting sacrifice events into damage and life-buffering Food loops.

Balanced artifact/attachment-permanent answer plan
Side in: 1 Abandon Attachments; 1 Origin of Metalbending; 1 Decorum Dissertation; 2 The Legend of Roku
Cut: 2 Deadly Dispute; 1 Witch's Oven; 1 Eyetwitch; 1 Ygra, Eater of All

- Use this exact plan only when card text checks and opponent permanents justify these role cards as concrete answers or engines. Do not dilute the sacrifice core against unknown opponents; this plan is for matchups where the named sideboard cards have confirmed text that solves a public permanent problem or creates a stronger battlefield plan than redundant draw and slow top-end.

- Against aggro, Add role cards: Pest Summoning if it makes blockers, Firebending Lesson if it kills a creature, Ozai's Cruelty or Ruinous Waterbending if confirmed as cheap interaction. Reduce main-deck emphasis: slow excess copies of Deadly Dispute, Scavenger's Talent, or Ygra, Eater of All only when survival requires earlier board impact.

- Against control, Add role cards: Thoughtseize, The Legend of Roku if confirmed as resilient value, Decorum Dissertation if confirmed as card advantage, and Unlicensed Hearse only when graveyards matter. Reduce main-deck emphasis: Fatal Push against creature-light builds and one redundant Witch's Oven when the opponent attacks engines instead of life total.

- Against graveyard decks, Add role cards: Unlicensed Hearse first, Thoughtseize when the enabler is spell-based, and any confirmed text-dependent exile or disruption from Ozai's Cruelty, Ruinous Waterbending, or The Legend of Roku. Reduce main-deck emphasis: slow card draw or redundant sacrifice pieces only after preserving a functional Cauldron Familiar plus Witch's Oven or Mayhem Devil engine.

- Against artifact, Aura, or attachment decks, Add role cards: Abandon Attachments if confirmed to answer the relevant objects, Origin of Metalbending if confirmed to interact on that axis, and Thoughtseize when the key threat must be taken before resolution. Reduce main-deck emphasis: removal that misses the opponent’s central permanent type, but keep Fatal Push if creature carriers or artifact creatures are visible.

- Against midrange mirrors, Add role cards: Thoughtseize for planeswalkers, sweepers, or haymakers; Unlicensed Hearse for recursion; The Legend of Roku and Decorum Dissertation only when confirmed as durable value. Reduce main-deck emphasis: narrow removal only when targets are scarce; otherwise keep sacrifice density because Mayhem Devil turns every exchange into pressure.

## Matchup Guidance

- Against aggro, prioritize survival through repeated trades before building maximum engine value. Keep hands with early black or red mana, Fatal Push, Bloodtithe Harvester, Eyetwitch, Cauldron Familiar plus Witch's Oven, or Mayhem Devil; avoid slow hands that only draw cards with Deadly Dispute or wait for Ygra, Eater of All. Add role cards: Pest Summoning if it produces a blocker, Firebending Lesson if card text check confirms creature removal or stabilization, Ozai's Cruelty and Ruinous Waterbending only if confirmed as cheap interaction. Reduce main-deck emphasis: slow copies of Deadly Dispute, Scavenger's Talent, and Ygra, Eater of All when the visible race is about the first four turns.

- Against control, commit threats in layers and protect the sacrifice engine from sweepers with Thoughtseize rather than overextending. Lead with Cauldron Familiar, Eyetwitch, Bloodtithe Harvester, or Fable of the Mirror-Breaker to demand answers, then use Witch's Oven, Deadly Dispute, and Scavenger's Talent to keep material flowing after removal. Add role cards: Thoughtseize, The Legend of Roku if Card text check required confirms resilient value, Decorum Dissertation if confirmed as card advantage, and Unlicensed Hearse only when graveyards matter. Reduce main-deck emphasis: Fatal Push against creature-light lists and one redundant Witch's Oven when the opponent is fighting permanents instead of racing life total.

- Against combo, become disruption plus clock, not a slow value deck. Mulligan toward Thoughtseize post-board, fast Mayhem Devil pressure, Fable of the Mirror-Breaker, and hands that can present Cauldron Familiar plus Witch's Oven while still interacting. Use Thoughtseize on the card that makes the opponent’s current visible or known line function; if the combo is graveyard-based, Unlicensed Hearse should pressure the graveyard before the critical turn rather than after the opponent has already represented a win. Add role cards: Thoughtseize, Unlicensed Hearse, and any confirmed text-dependent disruption from Ozai's Cruelty, Ruinous Waterbending, The Legend of Roku, or Decorum Dissertation. Reduce main-deck emphasis: Fatal Push when creature targets are absent and excess slow draw when the opponent can win before attrition matters.

- Against tempo, make the opponent spend mana on your recursive threats while you avoid walking key spells into obvious interaction. Cauldron Familiar plus Witch's Oven is excellent when established early because it blunts attacks and taxes removal; Bloodtithe Harvester and Fatal Push answer early pressure without forcing a large stack fight. Do not sacrifice too much material into Deadly Dispute if the opponent can punish the tempo loss with a protected threat. Add role cards: Thoughtseize for permission or bounce-heavy hands, Firebending Lesson or Ruinous Waterbending only if confirmed to answer threats efficiently. Reduce main-deck emphasis: expensive or slow setup when you need to keep mana open for Fatal Push, Bloodtithe Harvester activation, or Witch's Oven loops.

- Against midrange, preserve material and make every exchange favor Mayhem Devil, Scavenger's Talent, or Fable of the Mirror-Breaker. Fatal Push and Bloodtithe Harvester should answer creatures that pressure life total or threaten planeswalker-style advantage; Cauldron Familiar should be sacrificed opportunistically when the life drain or Mayhem Devil trigger changes combat math. Add role cards: Thoughtseize for haymakers, sweepers, or planeswalkers; Unlicensed Hearse when graveyards are relevant; The Legend of Roku and Decorum Dissertation only if Card text check required confirms durable advantage. Reduce main-deck emphasis: narrow Fatal Push only when visible targets are scarce; keep core sacrifice density because the deck wins attrition by converting artifacts, creatures, Food, Blood, and Treasure into damage and cards.

- Against big mana, pressure life total while using Thoughtseize to stop the payoff that invalidates small sacrifice loops. Mayhem Devil and Fable of the Mirror-Breaker are important clocks, and Den of the Bugbear or Sokenzan, Crucible of Defiance can add pressure after the opponent spends turns developing mana. Avoid hands that only answer small creatures if the opponent’s visible plan is lands, mana permanents, or top-end spells. Add role cards: Thoughtseize first, The Legend of Roku if confirmed to accelerate pressure or provide resilient value, Decorum Dissertation only if confirmed to disrupt or draw into pressure. Reduce main-deck emphasis: Fatal Push when targets are minimal and excess Witch's Oven pieces when Cauldron Familiar looping is too slow by itself.

- Against graveyard decks, deploy Unlicensed Hearse early enough to constrain setup, then keep sacrifice pressure advancing. Use Thoughtseize when the graveyard deck depends on a spell, enabler, or payoff still in hand; use Unlicensed Hearse activations on the cards that enable the next legal line shown by public information. Cauldron Familiar recursion is secondary if the opponent’s graveyard plan is faster than your life drain. Add role cards: Unlicensed Hearse, Thoughtseize, and confirmed graveyard-relevant text from Ozai's Cruelty, Ruinous Waterbending, or The Legend of Roku. Reduce main-deck emphasis: slow Deadly Dispute chains or redundant Scavenger's Talent only after preserving enough sacrifice material to keep Mayhem Devil live.

- Against artifact or enchantment decks, identify whether the relevant object is a creature carrier, a static engine, or a combo permanent before spending removal. Fatal Push and Bloodtithe Harvester cover creature-based artifact plans, but noncreature engines require confirmed sideboard text or Thoughtseize before resolution. Add role cards: Abandon Attachments if Card text check required confirms it answers the visible object class, Origin of Metalbending if confirmed to interact with artifacts or improve your artifact engine, Decorum Dissertation if confirmed to answer or outvalue the permanent type, and Thoughtseize when the key card is still in hand. Reduce main-deck emphasis: removal that misses the central permanent type, while keeping Fatal Push when creature carriers are visible.

- Against go-wide decks, value Mayhem Devil and Witch's Oven loops as board-control tools, not just reach. Fatal Push should remove lords, sacrifice payoffs, or creatures that make attacks lethal; Bloodtithe Harvester can trade early and later cash Blood into removal when the board stalls. Cauldron Familiar can repeatedly blank one attacker, but do not rely on life drain alone if the opponent’s next attack is lethal. Add role cards: Pest Summoning if it creates bodies, Firebending Lesson if confirmed as removal, Ozai's Cruelty or Ruinous Waterbending if confirmed to reduce a wide board. Reduce main-deck emphasis: slow Ygra, Eater of All or speculative Deadly Dispute when the immediate board requires bodies and removal.

- Against single-threat decks, conserve clean answers and avoid spending Fatal Push on low-impact creatures if the opponent’s plan clearly centers on one protected threat. Thoughtseize should take protection, the threat itself, or the spell that makes removal fail, based on visible hand information. Mayhem Devil triggers can finish damaged threats through sacrifice sequencing, and Bloodtithe Harvester gives a delayed answer if Blood is available. Add role cards: Thoughtseize, Ruinous Waterbending if confirmed as an answer to the threat class, Abandon Attachments if the threat depends on Auras or Equipment. Reduce main-deck emphasis: excess small blockers when the matchup is about answering one large or protected object.

- Against burn, protect life total and avoid converting too much life into mana smoothing unless the engine will immediately stabilize. Cauldron Familiar plus Witch's Oven is a premier plan because it gains life repeatedly while Mayhem Devil turns sacrifices into removal or reach; Blood Crypt and Overgrown Tomb decisions should respect current life total and visible lethal ranges. Add role cards: Pest Summoning if it blocks, Firebending Lesson only if confirmed as cheap removal or life-relevant interaction, Thoughtseize only when taking a high-impact card is worth the life and tempo. Reduce main-deck emphasis: slow Scavenger's Talent and Ygra, Eater of All when they do not affect the immediate race.

- Against removal-heavy decks, make removal awkward by leading with recursive, disposable, or value-generating permanents. Cauldron Familiar, Eyetwitch, Witch's Oven, Deadly Dispute, Scavenger's Talent, and Fable of the Mirror-Breaker all punish one-for-one removal; Mayhem Devil should be protected when possible because it turns every later sacrifice into pressure. Add role cards: Thoughtseize for sweepers and exile effects, The Legend of Roku or Decorum Dissertation if confirmed as persistent value, Unlicensed Hearse only when graveyards matter. Reduce main-deck emphasis: Fatal Push when the opponent has few creatures, while keeping enough interaction for creaturelands or must-kill threats.

## Specific Matchup Notes

- General note: exact opposing decklists are absent, so these notes are archetype-only and revealed cards override assumptions. Use legal actions and visible public information first; use these notes to rank Thoughtseize targets, Fatal Push targets, Bloodtithe Harvester removal, Unlicensed Hearse activations, and Mayhem Devil damage after the engine exposes legal choices.

- Versus creature aggro: prioritize staying alive over maximizing cards. Keep Cauldron Familiar plus Witch's Oven if it blanks attacks or buys turns, spend Fatal Push on the creature that changes the next combat most, and use Bloodtithe Harvester as either an early blocker or delayed removal. Add role cards: Pest Summoning if Card text check required confirms it creates blockers, Firebending Lesson if Card text check required confirms cheap removal, Ozai's Cruelty or Ruinous Waterbending only if confirmed to affect combat or remove creatures. Priority targets: lords, haste threats, sacrifice payoffs, and creatures that make the next attack lethal.

- Versus removal-heavy midrange or control: lead with sticky engines and force one-for-one answers to be inefficient. Cauldron Familiar, Witch's Oven, Eyetwitch, Deadly Dispute, Scavenger's Talent, and Fable of the Mirror-Breaker are better early commitments than exposing Mayhem Devil without sacrifice support. Add role cards: Thoughtseize for sweepers, exile effects, planeswalker-style engines, or finishers; The Legend of Roku and Decorum Dissertation only if Card text check required confirms durable value. Priority targets: sweepers before overcommitting, exile removal for Cauldron Familiar, and threats that ignore small life-drain races.

- Versus combo or big mana: become the clock and use discard to break the highest-impact turn. Thoughtseize should take the payoff, enabler, or protection spell that public hand information shows will matter soonest; Mayhem Devil, Fable of the Mirror-Breaker, Den of the Bugbear, and Sokenzan, Crucible of Defiance should pressure life total before the opponent’s larger plan stabilizes. Add role cards: Thoughtseize first, then The Legend of Roku or Decorum Dissertation only after Card text check required confirms speed, disruption, or resilient pressure. Priority targets: the card that unlocks the opponent’s next decisive turn, not the most expensive card by default.

- Versus graveyard decks: deploy Unlicensed Hearse before the graveyard is already lethal if the opening hand supports pressure. Use Unlicensed Hearse activations on publicly visible cards that enable the next legal graveyard action, and do not spend all sacrifice fuel on value if Mayhem Devil damage can shorten the clock. Add role cards: Unlicensed Hearse, Thoughtseize, and Ozai's Cruelty or Ruinous Waterbending only if Card text check required confirms graveyard or creature relevance. Priority targets: recursive threats, flashback-style resources, graveyard payoffs, and enablers still in hand.

- Versus artifact, Aura, or equipment shells: identify the actual axis before sideboarding or targeting. Fatal Push and Bloodtithe Harvester answer creature carriers, but noncreature engines need Thoughtseize or confirmed sideboard text. Add role cards: Abandon Attachments if Card text check required confirms it answers the visible permanent type, Origin of Metalbending if confirmed to interact with artifacts or improve artifact exchanges, and Decorum Dissertation if confirmed as relevant disruption or value. Priority targets: the creature carrying the engine, the engine permanent if answerable, or the hand card that makes removal fail.

## Risk Summary

- Mana risk: the deck needs early black and red while managing Blood Crypt and Overgrown Tomb life loss. Do not shock lands automatically against burn or aggro; do shock when the legal turn requires Fatal Push, Thoughtseize, Cauldron Familiar plus Witch's Oven, or Mayhem Devil on curve and the life total can absorb it.

- Matchup risk: the deck can mis-role as pure combo when it must be midrange. Against fast decks, stabilize first; against slow decks, convert sacrifice loops into pressure before the opponent’s top-end invalidates incremental drain.

- Draw risk: hands with engine halves but no payoff can durdle. Witch's Oven without Cauldron Familiar or Mayhem Devil is slow, Cauldron Familiar without sacrifice outlets is low impact, and Ygra, Eater of All should not be kept as the only meaningful plan in a hand that cannot reach or protect it.

- Over-sideboarding risk: cutting too much sacrifice density weakens Mayhem Devil, Deadly Dispute, Scavenger's Talent, and Cauldron Familiar. Add role cards for the matchup, but preserve enough creatures, artifacts, and sacrifice outlets to keep the deck’s core exchanges functional.

- Graveyard risk: Unlicensed Hearse can interfere with opposing graveyards, but the deck also relies on Cauldron Familiar recursion. Activate Hearse with public-purpose discipline, and avoid exiling cards that matter to your own available recursion unless the legal game state demands it.

- Sweeper and removal risk: overcommitting Mayhem Devil, Bloodtithe Harvester, and Fable of the Mirror-Breaker into visible sweeper pressure can lose the attrition plan. Use Thoughtseize to clear sweepers when possible, and keep Deadly Dispute or Witch's Oven lines available to convert removal into value.

- Closer risk: small drains may not beat a large stabilized board. Preserve Den of the Bugbear, Sokenzan, Crucible of Defiance, Fable of the Mirror-Breaker tokens, Mayhem Devil reach, and Ygra, Eater of All as closing routes when visible life totals show the loop alone is too slow.

- Interaction risk: Fatal Push and Bloodtithe Harvester are finite, so spending them on low-impact creatures can leave no answer for the decisive permanent. Rank targets by next-turn damage, engine importance, protection, and whether Mayhem Devil triggers can finish the same object later.

- Sequencing risk: sacrificing before all triggers, mana, and targets are understood can waste damage or cards. When Mayhem Devil, Deadly Dispute, Scavenger's Talent, Witch's Oven, Blood tokens, Food, and Treasure are all visible, choose the sequence that keeps legal mana open, assigns Mayhem Devil damage with purpose, and preserves the sacrifice object needed for the next prompt.

## Test Feedback Checklist

- Deciding factor: identify whether the game was decided by sacrifice-engine inevitability, early combat survival, mana friction, or failure to close. Record the turn where Cauldron Familiar, Witch's Oven, Mayhem Devil, Scavenger's Talent, Deadly Dispute, Fable of the Mirror-Breaker, or Ygra, Eater of All first changed the visible game plan.

- Mulligans: ask whether each keep had early black/red access, at least one proactive play, and a coherent engine or interaction plan. Flag hands that kept only Cauldron Familiar, only Witch's Oven, only Ygra, Eater of All, or removal without pressure.

- Mana: record every point where Blood Crypt, Overgrown Tomb, Blightstep Pathway, Blazemire Verge, Blackcleave Cliffs, Swamp, Den of the Bugbear, or Sokenzan, Crucible of Defiance constrained a legal play. Note whether life loss from shock lands mattered against pressure.

- Velocity: ask whether Deadly Dispute, Bloodtithe Harvester Blood tokens, Eyetwitch, Fable of the Mirror-Breaker, and Scavenger's Talent found action soon enough. Mark games where resources accumulated but did not convert into board, damage, or disruption.

- Engine: check whether Cauldron Familiar plus Witch's Oven was assembled, disrupted, ignored, or too slow. Track whether Mayhem Devil damage was aimed at life total, creatures, planeswalker-style permanents if visible, or wasted on low-impact targets.

- Removal: review every Fatal Push and Bloodtithe Harvester activation for target quality. Ask whether the target affected the next combat, protected an engine, stopped a combo turn, or could have been handled by Mayhem Devil triggers instead.

- Sideboard: record whether Thoughtseize, Unlicensed Hearse, The Legend of Roku, Ozai's Cruelty, Decorum Dissertation, Abandon Attachments, Origin of Metalbending, Firebending Lesson, Ruinous Waterbending, and Pest Summoning matched the matchup role. Use Card text check required for any unclear sideboard effect before drawing conclusions.

- Closing: ask whether the deck ended games through Mayhem Devil reach, Cauldron Familiar loops, Fable of the Mirror-Breaker pressure, Den of the Bugbear, Sokenzan, Crucible of Defiance, or Ygra, Eater of All. Flag games where the opponent stabilized above the deck's visible drain rate.

- Role: decide whether the pilot correctly became control against creature pressure, pressure against combo or big mana, and attrition against removal-heavy decks. Record any turn where the chosen action contradicted the visible role.

- Mistakes: identify missed sacrifice windows, premature Deadly Dispute, unnecessary Food use, overexposed Mayhem Devil, poor Thoughtseize target selection, and Bloodtithe Harvester saved too long or spent too early.

- Stranded cards: list cards stuck in hand for mana, timing, target, or matchup reasons. Separate lands, Fatal Push, Deadly Dispute, Fable of the Mirror-Breaker, Ygra, Eater of All, and sideboard cards.

- Overperformers and underperformers: name the exact cards that produced wins or failed under pressure. Compare performance by matchup, not just aggregate record.

## First Tuning Questions

- Card quantities: should Ygra, Eater of All stay at two copies if it is frequently stranded, or increase if it reliably closes stalled boards? Card text check required for exact tactical expectations before changing its role.

- Engine density: should the deck preserve four Cauldron Familiar, four Witch's Oven, four Mayhem Devil, and four Scavenger's Talent if opponents answer one axis easily? Reduce main-deck emphasis only if logs show repeated engine-halves without payoff.

- Card draw package: should Deadly Dispute remain four copies if sacrifice fodder is abundant but tempo losses matter? Check whether Eyetwitch and Bloodtithe Harvester tokens made it live or whether it sat idle.

- Removal balance: should Fatal Push remain four copies if creature matchups decide most losses, or should interaction shift toward discard and broader answers if noncreature engines are the problem? Do not infer absent removal needs from hidden information.

- Mana base: should Blood Crypt, Overgrown Tomb, Blightstep Pathway, Blazemire Verge, Blackcleave Cliffs, and Swamp counts change if early black/red failures recur? Track whether green access is relevant only for specific cards before adding pain to the deck.

- Aggro plan: should Pest Summoning, Firebending Lesson, Ozai's Cruelty, or Ruinous Waterbending occupy more sideboard space if creature pressure beats the main deck? Card text check required before assigning them anti-aggro status.

- Control plan: should Thoughtseize remain the main anti-control package, or should The Legend of Roku and Decorum Dissertation gain importance if they prove resilient value? Card text check required before treating either as a control plan.

- Graveyard plan: are two Unlicensed Hearse enough when graveyard decks are common, and does Hearse conflict with Cauldron Familiar recursion in actual games? Tune only from public graveyard interactions and logged legal activations.

- Artifact/enchantment plan: does Abandon Attachments or Origin of Metalbending answer the permanent types that beat this deck? Card text check required, then compare against using Thoughtseize or creature removal on the carrier.

- Closers: does Den of the Bugbear, Sokenzan, Crucible of Defiance, Fable of the Mirror-Breaker, Mayhem Devil, and Ygra, Eater of All close fast enough after stabilization? If not, identify whether the issue is clock speed, mana, or losing engines.

- Role conflict: does the deck lose when it tries to maximize value instead of protecting life total, or when it plays too defensively against combo? Use matchup-specific logs before changing card counts.

- Sideboard slot pressure: which sideboard cards were never legal, never chosen, or never high-impact? Keep Card text check required notes attached to The Legend of Roku, Ozai's Cruelty, Decorum Dissertation, Abandon Attachments, Origin of Metalbending, Firebending Lesson, Ruinous Waterbending, and Pest Summoning until verified.

Runtime cues: action:cast Ygra, Eater of All
Use when: deciding whether to commit Ygra, Eater of All as a large payoff. Card text check required for exact static and triggered effects.
Avoid when: the opponent has visible untapped interaction and the pilot has no backup pressure, or when casting Ygra, Eater of All prevents required survival interaction.
Instructions: Commit Ygra, Eater of All when it closes the game, converts existing Food/sacrifice material into a decisive board, or forces the opponent to answer while Mayhem Devil or Cauldron Familiar provides reach. Delay when current engine actions already win without exposing the payoff.

Use when: Thoughtseize is in the deck post-board and legal to cast.
Avoid when: life loss creates visible lethal exposure or the opponent hand is not revealed at the choice prompt.
Instructions: Cast Thoughtseize before committing fragile engines against combo, control, or decks with sweepers. Take the card that most directly stops current role execution: combo payoff, sweeper, efficient removal for Mayhem Devil/Ygra, or a threat the current hand cannot answer.

Runtime cues: action:activate Unlicensed Hearse; action:target card in graveyard
Use when: Unlicensed Hearse is post-board and graveyard targets are visible.
Avoid when: the activation would exile own Cauldron Familiar needed for an active Witch's Oven loop unless survival or denial requires it.
