# Strategy Specifications
## Deck Name And Archetype

Eldrazi is a Legacy aggro-stompy deck registered as 60 main-deck cards and 15 sideboard cards, and the supplied validation contract reports the list as format-aware legal for Legacy. The deck should be treated by Veles as a fast mana pressure deck whose tactical choices start from rules-engine legal actions, visible board state, public information, and exact action text; the pilot must not assume hidden opponent cards, unlisted sideboard cards, or deterministic outcomes that Forge has not exposed.

The registered archetype tags are aggro and stompy, with duplicate tag text in the source metadata normalized to the same two functional labels. The deck is not a generic Legacy Eldrazi stock import for strategy purposes: it is a hybrid Eldrazi Stompy shell using classic sol-land pressure from Ancient Tomb, Eldrazi Temple, Eye of Ugin, Cavern of Souls, Lotus Petal, Chalice of the Void, Thought-Knot Seer, and Reality Smasher, but it also leans on newer or more specialized cards such as It That Heralds the End, Glaring Fleshraker, Eldrazi Linebreaker, Wastescape Battlemage, Sire of Seven Deaths, Kozilek's Command, Eldrazi Confluence, Petrified Hamlet, and Abundant Countryside. Runtime policy should therefore prefer deck-specific evaluation over assumptions from older colorless Eldrazi lists.

The main-deck role is proactive disruption backed by large and scaling Eldrazi threats. Chalice of the Void and Thought-Knot Seer are the main disruptive pressure cards; Wastescape Battlemage, Kozilek's Command, and Eldrazi Confluence are flexible interaction or swing cards whose exact mode text must be respected at runtime; Glaring Fleshraker, Eldrazi Linebreaker, Sire of Seven Deaths, Reality Smasher, and It That Heralds the End provide the primary battlefield clock. Card text check required for any newer or unfamiliar card before Veles treats a choice as deterministic, especially for Wastescape Battlemage, Kozilek's Command, Eldrazi Confluence, Petrified Hamlet, Abundant Countryside, It That Heralds the End, Glaring Fleshraker, Eldrazi Linebreaker, and Sire of Seven Deaths.

The mana base is explosive but role-sensitive: Ancient Tomb, Eldrazi Temple, Eye of Ugin, Cavern of Souls, Lotus Petal, Petrified Hamlet, and Abundant Countryside should be evaluated as acceleration and spell-access tools before they are evaluated as generic lands. Wasteland appears as one main-deck copy and three sideboard copies, so the main deck has limited land-denial density before sideboarding; sideboard plans may transform that axis, but exact plans must never side in more than three Wasteland or cut more than one main-deck Wasteland unless the registered zones change.

The sideboard confirms a Legacy anti-combo and hate-card posture: Leyline of the Void covers graveyard pressure, Null Rod attacks artifact-based engines, Disruptor Flute supplies named-card or activated/triggered disruption if its visible text supports that use, Warping Wail offers a narrow flexible interaction slot, Karn's Sylex is a reset or containment tool if runtime text confirms it, and additional Wasteland improves mana denial. Every sideboard recommendation must name only these registered sideboard cards on `Side in:` lines.

Opponent information status is unspecified: no metagame opponent, known matchup, opening hand, public battlefield, or hidden-card reveal has been supplied for this guide batch. Veles should treat future matchup sections as archetype-conditional guidance until a game state, deck label, revealed card, public log, or sideboarding context provides more specific opponent evidence.

## Thesis

Eldrazi assembles explosive mana plus disruptive pressure: use Ancient Tomb, Eldrazi Temple, Eye of Ugin, Cavern of Souls, Lotus Petal, Petrified Hamlet, and Abundant Countryside to put Chalice of the Void, Thought-Knot Seer, Glaring Fleshraker, Eldrazi Linebreaker, It That Heralds the End, Reality Smasher, or Sire of Seven Deaths onto the battlefield ahead of normal Legacy pacing. Prioritize hands that convert acceleration into either a lock piece or a fast threat; a hand that only has mana or only has expensive creatures is not the deck's plan.

The deck wins by making the opponent's cheap spells or key card access awkward while large Eldrazi end the game before the opponent can rebuild. Chalice of the Void and Thought-Knot Seer are the cleanest disruption-threat bridge, while Kozilek's Command, Eldrazi Confluence, and Wastescape Battlemage should be treated as flexible tools whose mode and target choices must follow exact visible card text at runtime. Card text check required for newer or less familiar cards before treating any line as deterministic.

The deck is not trying to play a long generic control game, trade one-for-one indefinitely, or conserve every resource for perfect value. Spend Lotus Petal, Ancient Tomb life, and sometimes Wasteland aggressively when the visible game state shows that a fast disruptive threat or a lock piece will matter more than future resource depth. Do not over-sideboard into a slow hate deck unless the matchup demands a specific sideboard module.

Prioritize decisive deployment over speculative holding. Keep the pressure high, protect tempo when Cavern of Souls can make creature spells resilient, and use interaction to preserve a clock rather than to answer every visible permanent. Respect legal actions first: if Forge exposes only partial or modal choices for Kozilek's Command, Eldrazi Confluence, Wastescape Battlemage, Disruptor Flute, Warping Wail, or Karn's Sylex, choose only among the displayed legal actions and do not infer hidden mode availability.

## Role Package

- Threats: Thought-Knot Seer is the premium disruptive body and should usually be accelerated before slower standalone attackers when hand interaction is relevant. Glaring Fleshraker and Eldrazi Linebreaker are core multi-copy pressure cards; card text check required, but treat them as battlefield-snowball threats when their visible text rewards additional Eldrazi, colorless spells, combat pressure, or creature deployment. Reality Smasher is a single-copy heavy attacker, and Sire of Seven Deaths is a top-end finisher that should be committed when acceleration and board context justify tapping down.

- Payoffs: Chalice of the Void is the main prison payoff, especially when the visible matchup or known cards rely on low-cost spells. Thought-Knot Seer is the main information-and-disruption payoff because it can convert fast mana into a proactive discard effect plus clock. Kozilek's Command and Eldrazi Confluence are payoff interaction cards only when their exact legal modes advance the board, protect lethal pressure, answer a key permanent, or convert excess mana into material advantage.

- Engines: Eye of Ugin, Eldrazi Temple, and Ancient Tomb are the practical engine pieces because they compress turns and let the deck operate above rate. It That Heralds the End may function as an engine or scaling permanent if its visible text supports cost reduction, team enhancement, or Eldrazi scaling; card text check required. Glaring Fleshraker may also be an engine if runtime text shows triggered material from colorless or Eldrazi sequencing.

- Velocity: Lotus Petal is the burst-velocity card; spend it to land early Chalice of the Void, Thought-Knot Seer, or a pressure sequence when the payoff is immediate. Eye of Ugin, Eldrazi Temple, Ancient Tomb, Petrified Hamlet, Abundant Countryside, and Cavern of Souls are land-based velocity or access pieces, not merely mana sources.

- Interaction: Chalice of the Void disrupts spell texture, Thought-Knot Seer attacks the hand, Wasteland attacks mana, and Wastescape Battlemage, Kozilek's Command, Eldrazi Confluence, and Warping Wail provide conditional interaction subject to exact card text. Use interaction to keep the opponent from stabilizing against an existing or imminent clock.

- Protection: Cavern of Souls is the primary protection-like resource for creature deployment when the relevant creature type and spell legality are exposed. Chalice of the Void can protect pressure indirectly by cutting off cheap answers. Do not invent commander-style protection cards; none are registered.

- Recursion: The registered list has no clear recursion package. If a card's visible text unexpectedly offers recursion, treat that as card-text-dependent and do not plan around it before Forge exposes the legal action.

- Mana: Ancient Tomb, Eldrazi Temple, Eye of Ugin, Cavern of Souls, Lotus Petal, Petrified Hamlet, Abundant Countryside, and Wasteland define the resource model. Sequence lands to cast the most disruptive legal threat on time while preserving Cavern of Souls naming value and Wasteland timing when mana denial is strategically live.

- Sideboard modules: Leyline of the Void is the graveyard-hate module, Null Rod is the artifact-engine module, Disruptor Flute is the named-card or ability-disruption module if text confirms, Warping Wail is narrow flexible interaction, Karn's Sylex is a reset or containment tool if text confirms, and extra Wasteland expands the mana-denial module.

## Primary Win Conditions

- Disruptive fast-clock line: set up Ancient Tomb, Eldrazi Temple, Eye of Ugin, Cavern of Souls, or Lotus Petal to deploy Chalice of the Void or Thought-Knot Seer before the opponent’s normal curve stabilizes. Execute by pairing the first disruption piece with Glaring Fleshraker, Eldrazi Linebreaker, It That Heralds the End, Reality Smasher, or Sire of Seven Deaths as the clock; prioritize this line against unknown opponents, spell-dense decks, combo, and hands where early mana plus one threat is already present. Disruption is strongest when Chalice of the Void constrains cheap spells and Thought-Knot Seer removes the visible card most likely to beat the current board.

- Glaring Fleshraker pressure line: use Glaring Fleshraker as the main battlefield-snowball win path when its visible card text rewards colorless spells, Eldrazi sequencing, creature entries, tokens, or direct opponent damage. Card text check required before assuming exact triggers, but if Forge exposes legal actions that create extra bodies or damage from Kozilek's Command, Chalice of the Void, Lotus Petal-enabled sequencing, Eldrazi Linebreaker, It That Heralds the End, or other colorless permanents, prioritize the sequence that adds board plus life-pressure in the same turn. This line is best when blockers make pure combat slower or when the opponent’s life total can be compressed without needing every attacker to connect.

- Big Eldrazi finisher line: build toward Reality Smasher and Sire of Seven Deaths when the visible board calls for a single hard-hitting threat or when early disruption has bought a turn window. Setup requires enough lands or Lotus Petal acceleration to cast the finisher without losing to the immediate crack-back; execution favors committing the finisher after Thought-Knot Seer, Chalice of the Void, Wasteland, Kozilek's Command, Eldrazi Confluence, or Wastescape Battlemage has reduced the opponent’s ability to answer it. Prioritize this line against midrange, control, or stalled boards where small Eldrazi are no longer ending the game quickly.

## Secondary Win Conditions

- Chalice of the Void plus pressure is the main lock-adjacent backup plan, not a complete prison plan. Deploy Chalice of the Void when the visible matchup, revealed cards, or legal stack texture shows a key mana value, then use any credible body to end the game before the opponent draws around it. Do not keep spending turns adding lock texture if Glaring Fleshraker, Eldrazi Linebreaker, Thought-Knot Seer, Reality Smasher, or Sire of Seven Deaths can shorten the clock.

- Wasteland tempo can become a win condition when the opponent is light on mana, reliant on a specific nonbasic land, or already constrained by Chalice of the Void. Use the registered main-deck Wasteland to protect a clock, not to make a generic land trade that leaves this deck with expensive cards stranded. Extra Wasteland from the sideboard belongs to later Sideboard Map plans, not maindeck assumptions.

- Modal-card value is a fallback win path through Kozilek's Command, Eldrazi Confluence, and Wastescape Battlemage when Forge exposes modes that remove a blocker, add material, counter or exile a relevant object, or otherwise preserve lethal pressure. Card text check required for exact modes and targets; choose only legal runtime actions and prefer modes that change the current race or board, not modes that merely spend mana.

- Creature-dense combat remains viable when the disruptive plan is answered. It That Heralds the End and Eldrazi Linebreaker may improve combat math if their visible text confirms team sizing, attack pressure, haste, trample, or other combat relevance; card text check required. If no engine or lock sticks, keep presenting must-answer bodies and force the opponent to answer multiple different card names rather than waiting for the single best finisher.

- Recursion and creature-land wins are not registered plans. Do not hold resources for graveyard recursion, land animation, or inevitability unless Forge shows legal text from a visible registered card that explicitly creates that action.

## Emergency Lines

- Behind on life: stop paying Ancient Tomb for marginal tempo when another legal mana line exists, and prioritize stabilizing actions from Kozilek's Command, Eldrazi Confluence, Wastescape Battlemage, Thought-Knot Seer, or a large blocker. Commit Reality Smasher or Sire of Seven Deaths defensively only when it changes the race or blocks profitably; otherwise keep pressure focused on ending the game before burn or evasive attackers matter.

- Behind on board: use modal interaction first if it removes the key attacker, creates blockers, or opens a counterattack. Card text check required for Kozilek's Command, Eldrazi Confluence, and Wastescape Battlemage modes; do not infer a sweeper, exile mode, or token mode unless the legal action exists. If interaction is unavailable, deploy the largest body and preserve enough life to survive the next visible attack.

- Behind on cards: convert mana into high-impact threats rather than low-impact sequencing. Thought-Knot Seer is preferred when the opponent has cards in hand and the trigger is legal; Eye of Ugin may become threat access if its activated ability is visible, affordable, and legal. Avoid spending Lotus Petal or Wasteland for small tempo unless it immediately unlocks a threat, lock piece, or survival play.

- Behind on mana: prioritize land development and castable threats over speculative Wasteland lines. Lotus Petal should be spent to cross a concrete threshold such as Chalice of the Void, Thought-Knot Seer, Glaring Fleshraker, Eldrazi Linebreaker, or a modal answer, not to empty the hand without pressure.

- Facing combo or engine pressure: lead with the fastest legal disruption plus clock. Chalice of the Void, Thought-Knot Seer, Wasteland, and a quick finisher are the emergency plan in game one; Leyline of the Void, Null Rod, Disruptor Flute, Warping Wail, Karn's Sylex, and additional Wasteland become matchup-specific tools only after sideboarding guidance applies.

- Removed win conditions: pivot immediately to whichever registered threat remains legal and castable. The deck has many overlapping attackers, so do not overprotect Reality Smasher or Sire of Seven Deaths if Glaring Fleshraker, Eldrazi Linebreaker, It That Heralds the End, Thought-Knot Seer, and modal spells can still assemble a lethal board.

## Resource Model

- Life is a spendable acceleration resource until the opponent presents a short visible clock. Ancient Tomb should buy the first disruptive or threatening turn, but repeated Ancient Tomb activations become costly when the deck can cast the same spell through Eldrazi Temple, Eye of Ugin, Cavern of Souls, Petrified Hamlet, Abundant Countryside, Lotus Petal, or another legal source. When life is under pressure, choose mana lines that preserve life unless the Ancient Tomb line creates lethal, removes a decisive threat, or deploys a blocker that changes the next combat.

- Hand size is converted into board pressure and lock pressure quickly. Do not conserve Lotus Petal, Chalice of the Void, or early creatures for abstract value when the current legal sequence creates a turn-one or turn-two constraint plus a clock. Preserve cards only when the visible matchup rewards waiting, such as holding Kozilek's Command, Eldrazi Confluence, Wastescape Battlemage, Warping Wail, Disruptor Flute, or Null Rod for a known window after sideboarding.

- Mana is the deck's main bottleneck and its main advantage. Hands with sol-land output and castable action are worth more than hands with many expensive cards and no acceleration. Prioritize converting two-mana lands and Lotus Petal into Chalice of the Void, Glaring Fleshraker, Eldrazi Linebreaker, Thought-Knot Seer, Wastescape Battlemage, or It That Heralds the End before using Wasteland as a pure denial play.

- Board presence is the default resource to protect. Glaring Fleshraker, Eldrazi Linebreaker, It That Heralds the End, Thought-Knot Seer, Reality Smasher, Sire of Seven Deaths, and Wastescape Battlemage should pressure life totals while modal spells and disruption clear the path. Trade creatures only when the exchange preserves a stronger clock, stops lethal damage, or converts a small body into enough time for a larger Eldrazi.

- Graveyard and exile are not primary game-one resources for this deck. Treat the graveyard as mostly public history unless Forge exposes legal text from Kozilek's Command, Wastescape Battlemage, or another visible card that interacts with it; card text check required for exact modes. After sideboarding, Leyline of the Void turns graveyards into an opponent-denial axis rather than a value engine for this deck.

- Lands are both mana and disruption, so spend them according to the current clock. Wasteland is strongest when a threat is already attacking or when destroying a visible nonbasic land prevents the opponent from answering Chalice of the Void, Thought-Knot Seer, Glaring Fleshraker, or a finisher. Eye of Ugin may be a mana-like discount or a late threat-access land only if Forge exposes the legal action; card text check required before relying on an activated ability.

- Sacrifice fodder is incidental unless visible card text creates expendable bodies. If Glaring Fleshraker or Kozilek's Command produces tokens, treat them first as pressure, blockers, or mana-like material only according to Forge's legal actions. Do not assume sacrifice synergies beyond registered card text.

- Tempo is the deck's preferred currency. A play that makes the opponent spend a turn answering Chalice of the Void, Thought-Knot Seer, Glaring Fleshraker, Eldrazi Linebreaker, Reality Smasher, or Sire of Seven Deaths is usually better than a slower line with more theoretical value.

- Information is converted through Thought-Knot Seer and visible public actions. When Thought-Knot Seer reveals a hand, choose the card that most directly beats the current board or stops the next planned attack, lock piece, or finisher. Do not infer hidden cards after the reveal expires; use only visible state, logs, and current legal actions.

- Sideboard bullets change resource priorities after game one. Leyline of the Void spends opening-hand equity for graveyard denial, Null Rod spends card slots to attack artifact engines, Disruptor Flute spends mana and timing to tax or constrain a named line, Warping Wail adds flexible interaction if its legal modes matter, Karn's Sylex buys reset potential, and extra Wasteland increases land-denial pressure.

## Mana Guide

- Keep hands that have an immediate mana plan and at least one meaningful payoff. A strong opener usually contains Ancient Tomb, Eldrazi Temple, Eye of Ugin, Cavern of Souls, Lotus Petal, or enough lands to cast a disruptive permanent or threat by turn two. Mulligan hands that require drawing multiple specific mana pieces before casting Chalice of the Void, Glaring Fleshraker, Eldrazi Linebreaker, Thought-Knot Seer, Wastescape Battlemage, or It That Heralds the End.

- Count colorless requirements before choosing a land line. Ancient Tomb, Eldrazi Temple, Eye of Ugin, Cavern of Souls, Wasteland, and Lotus Petal may satisfy different parts of a cost depending on Forge's legal payment choices. Card text check required for Petrified Hamlet and Abundant Countryside; use them according to exposed mana abilities, tapped status, and produced colors.

- Lead with the land that unlocks the current turn and preserves future turns. Ancient Tomb is best when the life payment creates a fast Chalice of the Void, Thought-Knot Seer, Glaring Fleshraker, or Eldrazi Linebreaker. Eldrazi Temple is preferred for Eldrazi-heavy hands when it casts the same spell without life loss. Cavern of Souls is preferred before important creatures when the opponent can counter spells and Forge exposes the relevant creature-type choice.

- Use Lotus Petal to cross a specific threshold, not to empty the hand automatically. Spend Lotus Petal for turn-one Chalice of the Void, an accelerated threat, a required color or colorless payment, or a decisive modal interaction. Save Lotus Petal when the current spell can be cast without it and the next turn may need an extra mana for Thought-Knot Seer, Kozilek's Command, Eldrazi Confluence, Wastescape Battlemage, Reality Smasher, Sire of Seven Deaths, Disruptor Flute, Warping Wail, Null Rod, or Karn's Sylex.

- Sequence Wasteland after development unless the opponent's land is the visible bottleneck. If using Wasteland delays the first real threat, prefer casting pressure. Use Wasteland early when the opponent kept a low-land hand, relies on a visible nonbasic land, or when Chalice of the Void already limits cheap recovery.

- Play lands before draw or selection only when the mana is needed now or the land choice is strategically locked. If Kozilek's Command, Eye of Ugin, or another visible action could reveal, select, or change the turn's needs, delay the land drop when legal and safe. Play the land first when needing mana for the current action, when a tapped land must be deployed, when Cavern of Souls must name a type for a creature spell, or when Wasteland timing must deny an opponent before they untap.

- Choose tapped or utility lands by immediate usability. If Petrified Hamlet or Abundant Countryside enters tapped or has conditional mana text, card text check required; prefer untapped sol-land lines when tempo matters, and prefer the utility land when no current legal spell is lost.

- Sideboard mana pressure matters because bullets can be noncreature and timing-sensitive. Keep post-board hands only when they can cast the hate card on time and still produce a clock; Leyline of the Void is the exception when it begins the game on the battlefield through a legal pregame action.

## Mulligan Guide

- Strong keeps have fast mana, a disruptive or snowballing play, and a follow-up threat. Keep Ancient Tomb or Eldrazi Temple with Chalice of the Void plus Glaring Fleshraker, Eldrazi Linebreaker, Thought-Knot Seer, Wastescape Battlemage, It That Heralds the End, or Kozilek's Command when Forge shows a turn-one or turn-two legal line.

- Strong creature hands can keep without Chalice of the Void when they curve into pressure. Ancient Tomb plus Eldrazi Temple, Eye of Ugin, Cavern of Souls, Lotus Petal, or another usable land is strong if it casts Glaring Fleshraker or Eldrazi Linebreaker early and reaches Thought-Knot Seer by turn two or three.

- Medium keeps need one draw step to become explosive but already cast something relevant. A hand with Cavern of Souls, Eye of Ugin, Petrified Hamlet, or Abundant Countryside plus It That Heralds the End, Wastescape Battlemage, Kozilek's Command, and a larger Eldrazi is acceptable only if at least one early legal play exists; card text check required for exact utility-land and It That Heralds the End acceleration assumptions.

- Risky keeps are mana-heavy hands whose first play is late. Ancient Tomb, Eldrazi Temple, Eye of Ugin, Wasteland, and Cavern of Souls with only Reality Smasher or Sire of Seven Deaths should mulligan unless the matchup is slow, the hand has Chalice of the Void, or Forge exposes Eye of Ugin/It That Heralds the End actions that make the threat timely.

- Automatic ships cannot produce a meaningful action by turn two. Ship no-land hands, one-land hands without Lotus Petal or a legal one-mana/zero-mana plan, hands that rely on Wasteland as the only mana, and hands with Sire of Seven Deaths plus Reality Smasher but no acceleration.

- Matchup-dependent keeps prioritize the hate piece that matters, then the clock. Against cheap-spell decks, keep Chalice of the Void more aggressively; against graveyard decks after sideboarding, keep Leyline of the Void hands that still have a castable threat; against artifact engines, keep Null Rod or Disruptor Flute only when mana and pressure also exist.

- Play/draw changes how much risk is tolerable. On the play, favor Chalice of the Void, Ancient Tomb, Eldrazi Temple, and Thought-Knot Seer because tempo snowballs; on the draw, require more stable mana or a stronger interactive piece because a slow threat-only hand may already be behind.

- Trap hands look powerful but fail if the first relevant action is too late. Multiple Eye of Ugin, Wasteland, Sire of Seven Deaths, Reality Smasher, and Eldrazi Confluence without Ancient Tomb, Eldrazi Temple, Lotus Petal, or an exposed discount action should ship even though the card quality is high.

## Turn Arc

- Turn 1 should deploy the lock or the engine before optional denial. Prefer Ancient Tomb or Eldrazi Temple into Chalice of the Void when legal and strategically live; otherwise deploy Glaring Fleshraker, Eldrazi Linebreaker, It That Heralds the End, Lotus Petal acceleration, or Cavern of Souls setup for a protected Eldrazi creature.

- Turn 1 Wasteland is a deviation, not the default. Use Wasteland immediately only when the opponent's visible land is their bottleneck or when the hand already has another mana source and a follow-up threat; do not trade the first development turn for land denial without a clock.

- Turn 2 should convert mana into hand pressure or board pressure. Prefer Thought-Knot Seer when legal because it adds a body and attacks the opponent's next answer; prefer Glaring Fleshraker or Eldrazi Linebreaker when the hand can chain colorless spells; use Kozilek's Command or Wastescape Battlemage only when Forge exposes a mode that answers the current board or advances pressure.

- Turn 2 deviations should protect the snowball. Cast Chalice of the Void late if it still blocks visible lines, name through Cavern of Souls when counterplay is likely, or use Lotus Petal to bridge into Thought-Knot Seer rather than saving it for speculative late value.

- Turn 3 should either attack hard or break the opponent's recovery turn. Add Reality Smasher, Thought-Knot Seer, a second engine creature, or a high-impact Kozilek's Command line when legal; use Wasteland after establishing pressure if destroying a nonbasic land constrains removal, combo setup, or sweeper timing.

- Turns 4-5 should close the game before the opponent stabilizes. Keep attacking with Glaring Fleshraker, Eldrazi Linebreaker, Thought-Knot Seer, Wastescape Battlemage, Reality Smasher, and tokens if created; commit Sire of Seven Deaths or Eldrazi Confluence only when the visible board, mana, and stack make tapping out better than holding interaction.

- Late game should turn excess mana into inevitability without abandoning lethal attacks. Use Eye of Ugin only through Forge-exposed legal actions; card text check required for exact activated or discount text. Prioritize lethal combat, high-impact modal spells, and topdecked threats over low-impact Wasteland activations unless the opponent's visible land unlocks their comeback.

## Card Roles

- Chalice of the Void is the primary proactive disruption piece. Cast it early when Forge exposes a legal value that attacks the opponent's cheap-spell density, especially on the play with Ancient Tomb, Eldrazi Temple, or Lotus Petal acceleration; avoid automatic casting when the visible legal value would lock out your own needed Lotus Petal or other current follow-up more than it constrains the opponent.

- Thought-Knot Seer is the best bridge between pressure and interaction. Prioritize casting it when the opponent still has hidden hand resources and you can take the card that most threatens your clock, your Chalice of the Void, or your next large threat; do not delay it for speculative extra mana unless a visible stack or battlefield problem demands Kozilek's Command or Wastescape Battlemage first.

- Glaring Fleshraker is the snowball engine and should come down before redundant medium threats when the hand can cast multiple colorless follow-ups. Card text check required for exact trigger handling, but tactically treat it as a payoff that rewards chaining Chalice of the Void, Lotus Petal, Kozilek's Command, Thought-Knot Seer, Wastescape Battlemage, Eldrazi Linebreaker, and other Eldrazi spells; protect its tempo by sequencing cheap legal actions after it only when those actions still matter.

- Eldrazi Linebreaker is an early combat amplifier and pressure piece. Card text check required for exact pump, haste, color, and creature-type text; use it before attacks when legal action text indicates it increases immediate damage, and avoid running it out as a low-impact body when a same-turn Glaring Fleshraker, Chalice of the Void, or Thought-Knot Seer line better changes the opponent's next turn.

- Kozilek's Command is the flexible modal spell that should answer the current problem or convert excess mana into pressure. Card text check required for exact modes and targets; choose modes from visible needs, such as removing a small creature, making bodies, digging/selecting, or disrupting a graveyard or resource, and avoid using it as filler before combat if waiting one priority window may expose a better target without risking unused mana.

- Wastescape Battlemage is a utility creature first and a body second. Card text check required for exact kicker modes, colors, and target restrictions; cast it unkicked only when curve pressure matters, and hold it when visible artifacts, enchantments, permanents, or stack-adjacent problems are likely to make a kicked mode materially stronger. Do not assume a mode is legal unless Forge offers the target and payment.

- It That Heralds the End is a setup creature whose value depends on exact text and follow-up hand. Card text check required; cast it early when the legal action suggests acceleration, cost reduction, or engine support for the next Eldrazi sequence, but prefer immediate Chalice of the Void or Thought-Knot Seer when the matchup demands disruption before setup.

- Lotus Petal is acceleration, color fixing if Forge exposes colored payment, and a timing resource. Spend it to produce a turn-one Chalice of the Void, Glaring Fleshraker, Eldrazi Linebreaker, or a faster Thought-Knot Seer when the tempo swing is real; hold it when the hand already curves out and Wastescape Battlemage, Kozilek's Command, Eldrazi Linebreaker, or sideboard cards may need specific mana later. Do not sacrifice Lotus Petal before selecting the legal spell or payment line that actually needs it.

- Reality Smasher is a one-copy closer that should punish stabilized or nearly stabilized opponents. Card text check required for exact keywords and discard-protection text; cast it when the opponent is under pressure and a large hasty or resilient threat shortens the clock, but do not keep an opening hand around it unless the mana already supports earlier plays.

- Sire of Seven Deaths is the top-end threat for games where the deck reaches large mana. Card text check required for exact combat abilities and protection text; deploy it when tapping out creates a decisive board or lethal clock, and avoid treating it as a normal curve card in mulligans unless Ancient Tomb, Eldrazi Temple, Eye of Ugin, Lotus Petal, or other visible effects make it timely.

- Eldrazi Confluence is a singleton flexible spell, so it should be saved for board states where its visible modes matter. Card text check required; use it when Forge shows modes that remove blockers, create combat leverage, stabilize, or present lethal, and do not spend it merely because mana is available if a creature threat would apply equivalent pressure.

- Ancient Tomb is the best tempo land and the main reason to keep explosive hands. Use it early to power Chalice of the Void, Thought-Knot Seer, Glaring Fleshraker, Eldrazi Linebreaker, Wastescape Battlemage, or Kozilek's Command; track life total carefully because repeated Ancient Tomb activations can turn a winning race into a short-clock survival problem.

- Eldrazi Temple is the cleanest creature accelerator. Prefer it for Eldrazi creature turns when legal costs show a discount, especially Thought-Knot Seer, Reality Smasher, Sire of Seven Deaths, Wastescape Battlemage, Glaring Fleshraker, Eldrazi Linebreaker, and It That Heralds the End; use other lands for noncreature spells when preserving Eldrazi Temple mana improves the turn.

- Eye of Ugin is a powerful but text-sensitive land in this list. Card text check required for exact discount, tutor, and activation legality in Legacy; keep hands with Eye of Ugin only when another mana source or visible legal action prevents it from being too slow, and use its exposed actions as late-game inevitability only after immediate attacks and board actions are considered.

- Cavern of Souls is the anti-permission and color-fixing land when a creature-heavy hand needs a type choice. Choose the creature type that unlocks the most current and future legal creature spells, normally Eldrazi if Forge shows that it supports the hand; do not name around a single speculative card when the present hand requires a different type or color.

- Wasteland is a tempo-denial tool, not a main mana plan. Use it after developing pressure when destroying a visible nonbasic land delays removal, combo, a sweeper, or a stabilizing play; avoid sacrificing it before casting a threat unless the opponent's land is clearly their bottleneck and your remaining mana still functions.

- Petrified Hamlet is a registered mana source whose exact text matters for sequencing. Card text check required; treat it as a conditional or utility land until Forge shows its legal mana actions, and choose it over faster lands only when it does not cost an important spell this turn or when its exposed action enables the required color or Eldrazi line.

- Abundant Countryside is another text-sensitive mana source and should be evaluated by legal actions, not assumptions. Card text check required; play it early if it enters tapped or sets up future mana without costing a live spell, and delay it when Ancient Tomb, Eldrazi Temple, Cavern of Souls, or Lotus Petal enables immediate pressure or disruption.

- Land-heavy hands need a payoff before they are keeps. Ancient Tomb, Eldrazi Temple, Eye of Ugin, Cavern of Souls, Petrified Hamlet, Abundant Countryside, and Wasteland become strong only when paired with Chalice of the Void, Glaring Fleshraker, Eldrazi Linebreaker, Thought-Knot Seer, Wastescape Battlemage, Kozilek's Command, Reality Smasher, or Sire of Seven Deaths; do not keep mana without a clock or disruptive action.

- Redundant threats should be sequenced by impact, not mana efficiency alone. Cast the card that changes the opponent's next decision most: Chalice of the Void against cheap spells, Thought-Knot Seer against hidden answers, Glaring Fleshraker before colorless chains, Eldrazi Linebreaker before damage bursts, and Wastescape Battlemage or Kozilek's Command when a visible permanent or creature must be answered.

## Interaction Priorities

- Disrupt first when the opponent's next action is more dangerous than your next attack. Prefer Chalice of the Void, Thought-Knot Seer, Wasteland, Kozilek's Command, Wastescape Battlemage, Disruptor Flute, Null Rod, Warping Wail, Karn's Sylex, or Leyline of the Void only when Forge exposes a legal action that answers the visible problem or attacks the hidden-card axis the matchup actually uses.

- Name or set lock pieces by matchup texture, not habit. Chalice of the Void should attack dense cheap-spell turns when the visible deck, known cards, or game log indicates many same-cost spells; do not fire it into your own required cheap line if Lotus Petal or sideboard cards are still needed first. Disruptor Flute should be saved for a card or activated line that is visible, known from Thought-Knot Seer, or strongly implied by public game actions.

- Take the card with Thought-Knot Seer that invalidates your current clock first. Prioritize sweepers, fast combo pieces, efficient removal for Glaring Fleshraker or Eldrazi Linebreaker, prison answers to Chalice of the Void, and cards that beat a single large threat; ignore low-impact cantrips or redundant lands when the opponent already lacks time or mana to convert them.

- Spend Kozilek's Command on visible board problems before marginal value. Card text check required for exact modes; when Forge offers damage, exile, token, selection, or similar choices, use the mode that clears a lethal attacker, removes a combo or graveyard resource, finds pressure, or creates blockers. Do not assume it can remove a permanent unless the legal actions show that target.

- Use Wastescape Battlemage as interaction when its legal kicked mode answers a visible bottleneck. Card text check required for exact kicker costs and target classes; preserve it against artifacts, enchantments, small permanents, or tempo targets if the opponent is likely to present them, but cast it as pressure when your hand lacks a clock and no target class is visible.

- Use Wasteland after pressure unless mana denial is the whole turn. Destroy the land that enables the opponent's next stabilizing spell, combo color, or utility activation; ignore a nonbasic that does not change their next turn if sacrificing Wasteland delays Thought-Knot Seer, Glaring Fleshraker, Eldrazi Linebreaker, Reality Smasher, Sire of Seven Deaths, or a relevant sideboard card.

- Bait interaction with redundant threats before committing the scarce closer. Lead with Glaring Fleshraker, Eldrazi Linebreaker, Wastescape Battlemage, or Thought-Knot Seer when they force an answer; hold Reality Smasher, Sire of Seven Deaths, or Eldrazi Confluence until the opponent is tapped low, has been checked by Thought-Knot Seer, or is forced to answer the board first.

- Ignore small creatures when racing is already favored. Do not spend Kozilek's Command, Eldrazi Confluence, or Wastescape Battlemage on a blocker or attacker that cannot change the race unless it blocks a key lethal attack, carries equipment-like pressure, enables sacrifice value, or threatens a combo. Against creature swarms, interaction shifts toward blockers, scalable damage, Karn's Sylex, and preserving life from Ancient Tomb.

- Change priorities by archetype. Against combo, favor Chalice of the Void, Thought-Knot Seer, Disruptor Flute, Wasteland, and fast lethal over creature removal. Against control, preserve Cavern of Souls creature lines, sequence must-answer threats, and use Thought-Knot Seer to clear sweepers or finishers. Against graveyard decks, Leyline of the Void and Kozilek's Command graveyard modes matter more than marginal combat tempo. Against artifact decks, Null Rod, Wastescape Battlemage, and Karn's Sylex become higher-value than extra bodies.

## Combat And Trading Rules

- Attack when the board state makes the opponent answer you. This deck wins by converting Ancient Tomb, Eldrazi Temple, Eye of Ugin, Lotus Petal, and Cavern of Souls into fast damage, so default to attacking with Glaring Fleshraker, Eldrazi Linebreaker, Thought-Knot Seer, Reality Smasher, Wastescape Battlemage, and Sire of Seven Deaths unless blocking is required to survive the next visible attack.

- Preserve Glaring Fleshraker and Eldrazi Linebreaker when they are still engines. Card text check required for exact triggers and bonuses; avoid trading either for a low-impact blocker if upcoming colorless spells, Lotus Petal acceleration, Kozilek's Command, Chalice of the Void, or additional Eldrazi bodies can turn them into more damage than one combat exchange.

- Trade Thought-Knot Seer only when the exchange protects the disruptive lead. Trading is acceptable if it removes the opponent's best attacker, preserves a lethal race, or prevents the opponent from using the drawn replacement card effectively; avoid throwing it into a medium blocker when the opponent is mana constrained or still missing the card you exiled.

- Treat Ancient Tomb life loss as combat damage already taken. At 12 or less, avoid unnecessary Ancient Tomb activations when another mana source casts the same spell. At 8 or less, prioritize blockers, removal modes, and lethal math over extra development. At 5 or less, do not spend life for a nonlethal line unless failing to act loses immediately.

- Block only to protect a clock advantage or prevent lethal. Use expendable bodies or tokens from legal effects before risking Glaring Fleshraker, Eldrazi Linebreaker, Thought-Knot Seer, Reality Smasher, or Sire of Seven Deaths. Chump block when the next turn presents lethal or a lock; trade when the opponent's creature is their only way to race or stabilize.

- Force bad blocks with large threats. Reality Smasher and Sire of Seven Deaths should attack when Forge shows their combat abilities make blocking costly or ineffective; do not assume exact trample, haste, protection, annihilator, or ward text without the visible card details, but use them as closers when the opponent is low enough that any clean hit changes the game.

- Sequence combat before interaction when damage information matters. Attack first if the opponent's blocks reveal whether Kozilek's Command, Eldrazi Confluence, or Wastescape Battlemage must clear a creature; interact before combat if a blocker prevents profitable attacks, a lifelink-like threat changes the race, or a known instant-speed trick punishes waiting.

- Protect the engine over marginal damage in creature mirrors. Keep the permanent that multiplies future colorless spells, mana, or combat pressure; accept slower attacks if holding back one relevant blocker prevents a lethal crack-back. Against control and combo, shift toward maximum damage because blockers are less valuable than reducing the opponent's draw steps.

- Count lethal using visible legal actions only. Include currently legal attacks, known haste or pump only when Forge exposes it, Kozilek's Command or Eldrazi Confluence modes only when offered, and Glaring Fleshraker or Eldrazi Linebreaker triggers only when visible. Do not plan around hidden card text, unoffered modes, or assumed replacement effects.

## Selection And Tutor Rules

- Use Eye of Ugin tutoring as a late-game conversion tool, not as early setup. Activate it only when Forge shows the ability is legal, you can still respect the opponent's clock, and the searched creature will matter more than spending the mana on current hand actions.

- Search with Eye of Ugin for the creature that closes the visible game. Choose Sire of Seven Deaths when a single large threat is needed, Reality Smasher when immediate pressure is best and it is available, Thought-Knot Seer when the opponent still has a decisive hidden-card axis, or Glaring Fleshraker / Eldrazi Linebreaker when engine pressure plus multiple future colorless spells is stronger than one body. Card text check required for exact searchable restrictions; follow Forge's legal candidate list.

- Treat Kozilek's Command as pseudo-selection only when the board is not demanding interaction. Card text check required for exact modes; if Forge offers card selection, token, graveyard, or damage choices, prefer survival and disruption before digging. Use selection modes to find mana when stuck, pressure when the opponent is low, or interaction when the visible board threatens to outpace you.

- Bottom or pass over redundant mana once action density matters. Keep Ancient Tomb, Eldrazi Temple, Eye of Ugin, Cavern of Souls, Lotus Petal, Abundant Countryside, and Petrified Hamlet only when they unlock a specific visible spell, activated ability, kicked Wastescape Battlemage line, or sideboard card. After four or more functional mana sources, prefer creatures, Chalice of the Void, Kozilek's Command, or matchup interaction.

- Sequence land drops to preserve the widest legal action tree. Lead with Ancient Tomb or Eldrazi Temple when they cast a turn-one or turn-two lock piece or threat; use Cavern of Souls when a creature must resolve through permission; hold Wasteland until its sacrifice will not strand a stronger play. Do not play Eye of Ugin just because it is available if another land creates colored or untapped requirements for Wastescape Battlemage, sideboard cards, or future legal modes.

- Use Lotus Petal as selection by tempo, not as a free resource. Spend it when it creates Chalice of the Void, Thought-Knot Seer, Glaring Fleshraker, Eldrazi Linebreaker, Disruptor Flute, Null Rod, Leyline of the Void follow-up pressure, or a decisive Kozilek's Command window ahead of schedule. Preserve it when the same play is available from lands and a later kicked Wastescape Battlemage, Warping Wail, or Eldrazi Confluence line may need exact mana.

- Treat no-card-draw hands as normal if they present pressure plus disruption. This deck selects by mulligan, mana sequencing, Eye of Ugin, and Kozilek's Command rather than abundant draw; do not overvalue speculative selection when the current hand already casts Chalice of the Void, Thought-Knot Seer, and a fast attacker.

## Priority And Stack Rules

- Use priority to convert mana advantage into forced decisions. Cast Chalice of the Void before giving the opponent cheap-spell windows when the chosen value is legal and strategically selected; cast Thought-Knot Seer before lower-impact attackers when seeing and taking a card changes whether the opponent can answer the board.

- Let harmless spells resolve when your clock and lock pieces already constrain the opponent. Do not spend Kozilek's Command, Warping Wail, Eldrazi Confluence, Wastescape Battlemage, Disruptor Flute, or Wasteland on a stack or permanent action unless Forge exposes a legal response that stops a payoff, protects lethal, prevents stabilization, or denies the mana required for the opponent's next critical play.

- Respond at the last useful window when information improves the choice. Hold instant-speed Kozilek's Command, Warping Wail, and Eldrazi Confluence until the opponent commits a target, attack, block, graveyard action, or stack spell, unless tapping out now prevents a more dangerous line. Card text check required for exact modes and target classes; choose only from offered legal actions.

- Use Disruptor Flute before the named card can matter. Card text check required for exact naming and activated/static effects; name a card only from public information, revealed cards, repeated game actions, or matchup-guided inference. If no reliable name exists and pressure is available, prefer deploying threats over speculative activation.

- Use Wasteland in priority windows that deny the next visible play. Destroy the nonbasic that enables a spell on stack only if rules-engine output shows that mana denial can still matter, or use it before the opponent untaps when their land is the bottleneck. Do not sacrifice Wasteland into open uncertainty when it delays your next Thought-Knot Seer, Reality Smasher, Sire of Seven Deaths, or sideboard lock piece.

- Decline optional payments or modes that consume tempo without changing the game. Pay extra costs, kick Wastescape Battlemage, or choose larger X / modal values only when the offered legal action answers a visible permanent, wins a race, protects a lock, or creates a materially faster clock. Preserve mana when passing with Warping Wail, Kozilek's Command, or Eldrazi Confluence is more important.

- Sequence combat tricks and removal around declared blocks. If Forge gives priority after blockers, use Kozilek's Command, Eldrazi Confluence, or Warping Wail only when the visible result saves a key attacker, kills a blocker, prevents lethal crack-back, or pushes lethal damage. If no legal action changes combat math, pass promptly.

- Respect Chalice of the Void symmetry from visible legality. Do not cast spells into your own lock unless Forge presents the action as legal and the resulting stack behavior is acceptable. If a spell is countered or unavailable because of Chalice of the Void, route the turn through creatures, Eye of Ugin, Wasteland, or combat instead.

## Sideboard Map

- Sideboard by preserving the deck's pressure-plus-tax identity. Keep enough early mana, Chalice of the Void, and Eldrazi bodies to end the game before the opponent rebuilds; sideboard cards should either stop the opponent's primary engine or buy the one turn needed for Thought-Knot Seer, Glaring Fleshraker, Eldrazi Linebreaker, Reality Smasher, or Sire of Seven Deaths to finish.

- Use Leyline of the Void as the graveyard-axis package. Bring it against graveyard combo, recursive creature engines, graveyard-based card advantage, and decks where the first turns are decided by whether graveyard resources exist. It is bad when the opponent's graveyard is incidental, when a late draw would be nearly blank, or when your opener already lacks pressure and mana. Role change: with Leyline of the Void in the opener, mulligan pressure can be slightly lower if the graveyard lock is decisive, but do not keep a hand that cannot cast threats before the opponent finds non-graveyard answers.

- Use Null Rod as the artifact-engine package. Bring it against artifact mana, artifact combo, artifact card-advantage engines, and decks relying on activated artifact abilities. Card text check required for exact affected abilities; assume it may also reduce the value of your own Lotus Petal, so plan land sequencing before casting it. Null Rod is bad when the opponent's artifacts are mostly static bodies, when your hand needs Lotus Petal to function, or when the matchup is decided by creatures and removal instead of artifacts.

- Use Disruptor Flute as the flexible name-and-tax package. Bring it against combo decks with a small number of payoff names, control decks leaning on one sweeper or stabilizer, and known engines revealed by Thought-Knot Seer or prior games. Card text check required for exact timing, naming, and tax/ability text. It is bad when you cannot name from public information, when the opponent's threats are redundant across many names, or when spending mana on another Eldrazi body would create lethal pressure faster.

- Use Wasteland as the mana-denial package. Bring extra Wasteland against greedy nonbasic mana, land-combo shells, decks using few colored sources, and control decks that need specific lands to stabilize. It is bad against basic-heavy decks, fast creature decks where sacrificing a land slows your clock, or hands that need every land to cast Thought-Knot Seer, Wastescape Battlemage, Eldrazi Confluence, Reality Smasher, or Sire of Seven Deaths. Role change: after adding Wasteland, value Eldrazi Temple, Ancient Tomb, Cavern of Souls, and Eye of Ugin openers that still cast spells after one land is sacrificed.

- Use Warping Wail as the narrow interactive flex card. Bring it against sorcery-speed combo, small utility creatures if Forge confirms legal targets, and matchups where making a small body matters for tempo or blocking. Card text check required for exact modes. It is bad against large creature decks, instant-speed engines, and board states where a single narrow answer does not affect the race.

- Use Karn's Sylex as the reset or prison-punish flex card. Card text check required before relying on exact activated, enters-tapped, or mana-value behavior. Bring it against low-to-the-ground permanent boards, artifact/creature swarms, and decks that overcommit permanents below your large Eldrazi curve. It is bad when you are the only player building a board, when the opponent's threats are too large or stack-based, or when spending a turn on a slow permanent gives the opponent time to answer your lock.

- Against spell combo, add role cards: Disruptor Flute, Warping Wail, Leyline of the Void when the graveyard is part of the engine, and Null Rod when artifact mana or artifact abilities are visible or strongly expected. Reduce main-deck emphasis: Eldrazi Confluence, the slowest top-end creature, and redundant combat-only pressure. Keep Chalice of the Void and Thought-Knot Seer central because they create the fastest disruption clock.

- Against fair blue control, add role cards: Wasteland and Disruptor Flute. Reduce main-deck emphasis: narrow battlefield interaction and the least efficient top-end copy. Use Cavern of Souls to force key creatures through permission, then use Disruptor Flute names from public information rather than guessing. Do not overload on cards that fail to attack unless they stop a revealed sweeper, planeswalker-like stabilizer, or engine card.

- Against creature aggro, add role cards: Karn's Sylex, Warping Wail if legal targets matter, and selective Disruptor Flute for known payoffs. Reduce main-deck emphasis: slow expensive threats and low-impact utility. Keep enough bodies to block and race; do not dilute into a control deck unless the sideboard card visibly breaks the board.

- Against artifact decks, add role cards: Null Rod, Disruptor Flute, Karn's Sylex, and sometimes Wasteland if their mana base is nonbasic-constrained. Reduce main-deck emphasis: Lotus Petal first because Null Rod can make it poor after deployment, then slow top-end. Sequence Lotus Petal before Null Rod only when it accelerates the lock or a Thought-Knot Seer into the same decisive turn.

- Against land-combo or nonbasic-heavy ramp, add role cards: Wasteland and Disruptor Flute, with Warping Wail only when a legal sorcery or small-creature axis exists. Reduce main-deck emphasis: slow standalone threats that do not disrupt. Use Wasteland after the opponent commits to a bottleneck land or before untap when it denies their next critical action; do not sacrifice it if doing so strands your own Eldrazi curve.

- Against unknown opponents after Game 1, sideboard from observed public causes of loss. Add Leyline of the Void only for graveyard dependency, Null Rod only for artifact dependency, Wasteland only for nonbasic bottlenecks, Disruptor Flute only when a name can be justified, Warping Wail only when a mode has likely targets, and Karn's Sylex only when the opponent wins by battlefield volume.

## Matchup Guidance

- Aggro: become the larger-board tempo deck, not a pure lock deck. Keep hands that cast Chalice of the Void or a fast body through Ancient Tomb, Eldrazi Temple, Eye of Ugin, Lotus Petal, or Cavern of Souls, then force combat around Thought-Knot Seer, Glaring Fleshraker, Eldrazi Linebreaker, It That Heralds the End, and Wastescape Battlemage. Add role cards: Karn's Sylex, Warping Wail when legal targets exist, and Disruptor Flute only for a known high-impact card. Reduce main-deck emphasis: Sire of Seven Deaths, Eldrazi Confluence, and the slowest nonessential threat when the game is decided before top-end matters. Avoid Ancient Tomb damage when a normal land curve still stabilizes.

- Control: prioritize uncounterable pressure and targeted disruption over maximum speed. Use Cavern of Souls to resolve Thought-Knot Seer, Eldrazi Linebreaker, Glaring Fleshraker, or Sire of Seven Deaths through permission, and use Thought-Knot Seer to remove sweepers, card-advantage engines, or clean answers visible in the opponent's hand. Add role cards: Wasteland for nonbasic bottlenecks and Disruptor Flute for a card name justified by public information. Reduce main-deck emphasis: narrow battlefield-only interaction and slow cards that walk into a sweeper without adding disruption. Do not sacrifice Wasteland if the lost mana prevents the next threat from resolving.

- Combo: race only when disruption is already present or the legal line is clearly lethal. Chalice of the Void, Thought-Knot Seer, Disruptor Flute, Warping Wail, Leyline of the Void, Null Rod, and Wasteland are the primary disruption families, but each applies to different combo engines. Add role cards according to visible dependency: Leyline of the Void for graveyard engines, Null Rod for artifact abilities or artifact mana, Wasteland for land bottlenecks, Disruptor Flute for named payoff or enabler cards, and Warping Wail when the legal mode interacts with the combo turn. Reduce main-deck emphasis: Eldrazi Confluence, Reality Smasher, Sire of Seven Deaths, and excess combat-only pressure. Commit Lotus Petal early only when it creates a same-turn lock or Thought-Knot Seer.

- Tempo: protect the mana curve from soft permission and mana denial before chasing perfect acceleration. Cavern of Souls is premium for creature-heavy hands, while Lotus Petal is best when it forces a turn-one Chalice of the Void, Thought-Knot Seer, or Glaring Fleshraker before the opponent can trade mana efficiently. Add role cards: Disruptor Flute for a known interactive bottleneck and Wasteland when the opponent's mana is visibly greedy. Reduce main-deck emphasis: expensive spells that can be stranded after Wasteland pressure or bounce. Prefer deploying multiple threats over one oversized threat if the opponent is representing single-target removal or bounce.

- Midrange: make every turn ask whether the opponent can answer both the board and the lock piece. Thought-Knot Seer should take the card that breaks the immediate combat or stabilizes the next turn, not the most expensive card by default. Glaring Fleshraker and Eldrazi Linebreaker pressure life totals while leaving bodies to punish removal-heavy exchanges if Forge confirms token or combat text. Add role cards: Wasteland against nonbasic-heavy builds, Disruptor Flute for known haymakers, and Karn's Sylex only when the opponent floods the board with smaller permanents. Reduce main-deck emphasis: low-impact acceleration after the opening turns and narrow top-end when removal plus blockers will decide the game.

- Big mana: attack the bottleneck before the payoff resolves. Use Wasteland and extra Wasteland to cut off nonbasic lands that produce multiple mana, colors, or engine utility, then follow with Thought-Knot Seer to remove payoff cards or recovery tools. Chalice of the Void is still valuable when it hits their early search or acceleration, but do not assume a number without legal action and matchup context. Add role cards: Wasteland and Disruptor Flute, with Warping Wail only when a legal mode matters. Reduce main-deck emphasis: cards that only win creature combat. Hold Sire of Seven Deaths or Reality Smasher until the mana line supports them without giving up disruption unless the opponent is already under a short clock.

- Graveyard: mulligan more aggressively for Leyline of the Void only when the opponent's public plan depends on graveyard access. Keep a Leyline of the Void hand that also casts pressure; do not keep a nonfunctional hand just because Leyline appears. Thought-Knot Seer should take the non-graveyard answer, alternate engine, or payoff that still matters through Leyline. Add role cards: Leyline of the Void, Disruptor Flute, and Warping Wail if its legal mode disrupts the setup. Reduce main-deck emphasis: Eldrazi Confluence and slower top-end. Continue attacking; graveyard decks often rebuild if the lock piece does not end the game.

- Artifact and enchantment engines: identify whether the opponent's artifacts or enchantments are mana, activated abilities, static lock pieces, or battlefield volume. Null Rod is for artifact abilities and artifact mana; Card text check required for exact affected abilities and own Lotus Petal implications. Wastescape Battlemage may matter against artifacts or enchantments only if Forge exposes legal targets; Card text check required before treating it as reliable removal. Add role cards: Null Rod, Disruptor Flute, Karn's Sylex, and sometimes Wasteland. Reduce main-deck emphasis: Lotus Petal when Null Rod is coming in, plus slow top-end. Sequence Lotus Petal before Null Rod when it enables the decisive same-turn play.

- Go-wide: become the stabilizing deck until a single attack is lethal. Chalice of the Void can slow cheap creature chains, but the game is often decided by blocking, preserving life against Ancient Tomb damage, and timing Karn's Sylex or Kozilek's Command if Forge confirms relevant modes. Add role cards: Karn's Sylex, Warping Wail when legal, and Disruptor Flute for a known payoff. Reduce main-deck emphasis: Sire of Seven Deaths, Reality Smasher, and expensive non-stabilizing cards. Do not attack with a needed blocker unless the visible crack-back is survivable or the attack creates lethal pressure.

- Single-threat decks: answer the support system and win the race around one large object. Thought-Knot Seer should remove protection, evasion, or the next threat if the current threat cannot be answered. Kozilek's Command, Eldrazi Confluence, Warping Wail, Wastescape Battlemage, and Karn's Sylex require legal modes from Forge before being treated as answers; Card text check required for exact target limits. Add role cards: Disruptor Flute for known threat names and Wasteland if the threat depends on a specific land. Reduce main-deck emphasis: swarm-only cards. Race with Eldrazi Linebreaker, Glaring Fleshraker, Thought-Knot Seer, Reality Smasher, and Sire of Seven Deaths when removal is not available.

- Burn: treat Ancient Tomb as a conditional resource, not a free accelerator. Keep Chalice of the Void hands highly when they also cast threats, and use Thought-Knot Seer to remove the card that most changes the next two turns of damage. Add role cards: Disruptor Flute if a key burn spell or engine name is known, Warping Wail only if a legal mode matters, and Karn's Sylex only for creature-heavy versions. Reduce main-deck emphasis: Sire of Seven Deaths and slow cards. Avoid paying life for speed unless the accelerated play prevents more damage than Ancient Tomb costs.

- Removal-heavy decks: diversify threat types and avoid committing all premium creatures into one sweeper. Cavern of Souls helps resolve bodies, but it does not protect them after resolution; Thought-Knot Seer should take sweepers, edicts, or exile effects when visible. Glaring Fleshraker is valuable if its token or damage engine is confirmed by Forge because it can leave material after trades. Add role cards: Disruptor Flute for known removal or sweeper names and Wasteland for control mana bottlenecks. Reduce main-deck emphasis: fragile acceleration once both players are trading resources. Deploy Sire of Seven Deaths only when it is likely to survive or when waiting gives the opponent more time than pressure gains.

## Specific Matchup Notes

- General/archetype-only: exact opponents are absent, so revealed cards and Forge legal actions override all archetype assumptions. Use the opponent's public lands, graveyard, stack, and shown hand from Thought-Knot Seer to classify the game before choosing Chalice of the Void numbers, Wasteland targets, Disruptor Flute names, or whether to commit Sire of Seven Deaths.

- Fast spell-combo: prioritize a turn-one lock or discard-style disruption over raw damage. Chalice of the Void, Thought-Knot Seer, Disruptor Flute, and Leyline of the Void are the relevant role cards depending on whether the visible engine uses cheap spells, a named payoff, or the graveyard. Add role cards: Disruptor Flute, Leyline of the Void when graveyard dependence is public or strongly indicated, and Warping Wail only when Forge exposes a relevant legal mode. Reduce main-deck emphasis: Eldrazi Confluence, Sire of Seven Deaths, and slow threat-only hands.

- Blue tempo or permission: make Cavern of Souls, Eldrazi Temple, Eye of Ugin, and Wasteland do the work before spending Lotus Petal. Thought-Knot Seer should take the interaction or tempo card that prevents the next threat from ending the game; do not assume the opponent has a specific counterspell unless it is revealed. Add role cards: Wasteland and Disruptor Flute for a known bottleneck. Reduce main-deck emphasis: fragile all-in Lotus Petal lines unless they force Chalice of the Void or Thought-Knot Seer before the opponent has mana.

- Creature races: preserve life total against Ancient Tomb and only race when the visible crack-back is smaller than your next attack. Eldrazi Linebreaker, Glaring Fleshraker, Thought-Knot Seer, Reality Smasher, and Sire of Seven Deaths are pressure, but blocking can be the winning line when the opponent is wider. Add role cards: Karn's Sylex for board volume and Warping Wail when a legal creature-related mode appears; Card text check required for exact mode limits. Reduce main-deck emphasis: slow top-end when early survival is the constraint.

- Artifact or activated-ability engines: use Null Rod only when its restriction hurts the opponent more than your own Lotus Petal timing. Sequence Lotus Petal before Null Rod when the current turn needs the mana, then stop relying on Petal afterward if Forge confirms the lock matters. Add role cards: Null Rod, Disruptor Flute, Karn's Sylex, and Wasteland. Reduce main-deck emphasis: Lotus Petal in slower post-board games and expensive cards that do not interact with the engine.

- Graveyard engines: keep Leyline of the Void hands that still cast pressure, not hands that only contain hate. Thought-Knot Seer should take the answer to Leyline of the Void, the non-graveyard alternate plan, or the payoff that still matters through hate. Add role cards: Leyline of the Void, Disruptor Flute, and Warping Wail when legal. Reduce main-deck emphasis: Eldrazi Confluence and slow closers.

## Risk Summary

- Mana risk: this deck can produce explosive starts but can also strand colorless-heavy, Eye of Ugin-heavy, or Lotus Petal-dependent hands. Mulligan hands that cannot cast a meaningful first or second play, and avoid sacrificing Lotus Petal into a line that leaves Thought-Knot Seer, Glaring Fleshraker, or Eldrazi Linebreaker uncastable next turn.

- Matchup risk: Chalice of the Void is matchup-defining but can be low impact at the wrong number. Choose the number from revealed cards, visible mana, prior game evidence, and legal action context rather than a default heuristic.

- Draw risk: redundant lands and late Lotus Petal can lose long games if early pressure was answered. Use Eye of Ugin, creature density, and any Forge-confirmed selection from Kozilek's Command to convert mana into action when legal, but do not invent tutor or selection text.

- Over-sideboarding risk: adding too many reactive cards can dilute the deck's best draws. Keep enough Eldrazi Linebreaker, Glaring Fleshraker, Thought-Knot Seer, Reality Smasher, and Sire of Seven Deaths pressure to end the game after disruption lands.

- Graveyard risk: Leyline of the Void is powerful only when the opponent's plan actually uses the graveyard. Against decks with a normal board plan, do not keep weak hands or reduce too much pressure just to start with Leyline of the Void.

- Sweeper/removal risk: single-threat lines expose the deck to removal, edicts, bounce, or sweepers. Diversify with multiple threats when possible, use Thought-Knot Seer to take the visible answer, and commit Sire of Seven Deaths only when the clock or resilience justifies it.

- Closer risk: Reality Smasher and Sire of Seven Deaths can be stranded or unnecessary when smaller Eldrazi already win. Prefer the lower-risk lethal line over tapping out for a larger closer unless waiting gives the opponent a better recovery window.

- Interaction risk: Kozilek's Command, Eldrazi Confluence, Wastescape Battlemage, Warping Wail, and Karn's Sylex require Forge-exposed legal modes and targets. Card text check required before treating any one of them as guaranteed removal, protection, or sweep.

- Sequencing risk: Ancient Tomb damage, Lotus Petal timing, Null Rod, Wasteland, and Cavern of Souls naming can turn a winning opener into a locked hand. Sequence disruption first only when it still leaves a castable threat; sequence threats first only when the opponent cannot visibly punish the delay.

## Test Feedback Checklist

- Deciding factor: record whether the game was won by early lock pressure, fast Eldrazi damage, mana denial, graveyard hate, or a large closer. Tie the answer to visible cards such as Chalice of the Void, Thought-Knot Seer, Eldrazi Linebreaker, Glaring Fleshraker, Wasteland, Leyline of the Void, Reality Smasher, or Sire of Seven Deaths.

- Mulligan quality: note whether the opener produced a meaningful first or second play without relying on hidden assumptions. Flag hands where Eye of Ugin, Ancient Tomb, Eldrazi Temple, Cavern of Souls, Lotus Petal, Petrified Hamlet, or Abundant Countryside created explosive starts, stranded cards, or unnecessary life loss.

- Mana execution: check whether Ancient Tomb damage was worth the tempo gained. Track whether Lotus Petal was spent to create a decisive lock or threat, or whether it caused later mana shortages after Chalice of the Void, Thought-Knot Seer, Glaring Fleshraker, or Eldrazi Linebreaker.

- Velocity: record whether the deck presented enough pressure after disruption. A game where Chalice of the Void or Leyline of the Void worked but no threat followed should be treated differently from a game where Eldrazi Linebreaker, Glaring Fleshraker, Thought-Knot Seer, or Reality Smasher closed quickly.

- Engine performance: verify what Glaring Fleshraker and It That Heralds the End actually did in Forge logs before crediting them. Card text check required if the log does not clearly show triggers, cost reductions, tokens, or damage outcomes.

- Interaction value: record each meaningful use of Thought-Knot Seer, Wastescape Battlemage, Kozilek's Command, Eldrazi Confluence, Warping Wail, Disruptor Flute, Null Rod, Karn's Sylex, and Wasteland. Card text check required for mode-specific conclusions unless Forge exposed the exact legal mode and result.

- Sideboard impact: ask whether each sideboard card added pressure, bought time, or stranded in hand. Separate the performance of Leyline of the Void, Disruptor Flute, Null Rod, Wasteland, Warping Wail, and Karn's Sylex instead of judging the whole sideboard plan as one package.

- Closing discipline: review whether Sire of Seven Deaths or Reality Smasher was necessary, too slow, or safer than spreading threats. Mark games where a lower-cost Eldrazi line would have won without exposing the deck to a visible answer.

- Role accuracy: decide whether the pilot correctly played as aggro, prison-aggro, mana denial, or defensive stabilizer. A role error is present when the chosen line ignored visible pressure, known answers from Thought-Knot Seer, or the opponent's public mana constraints.

- Mistake review: identify any pass, attack, block, Chalice of the Void number, Wasteland target, Cavern of Souls naming choice, or modal spell choice that looked wrong from legal actions and visible state. Do not call a mistake based on hidden cards.

- Stranded-card review: list cards that stayed uncastable or low impact for multiple turns. Pay special attention to Sire of Seven Deaths, Eldrazi Confluence, Kozilek's Command, Wastescape Battlemage, Null Rod after Lotus Petal sequencing, and extra Eye of Ugin or Cavern of Souls draws.

- Overperformers and underperformers: name the exact cards that changed game outcomes, then state the board state that made them good or weak. Avoid broad conclusions from one game unless the same pattern repeats across matchups.

## First Tuning Questions

- Mana base quantity: are 4 Ancient Tomb, 4 Eldrazi Temple, 4 Eye of Ugin, 4 Cavern of Souls, 4 Petrified Hamlet, 4 Abundant Countryside, and 1 Wasteland producing enough turn-one and turn-two action without too many nonfunctional or painful starts?

- Acceleration quantity: is 4 Lotus Petal enabling decisive Chalice of the Void, Thought-Knot Seer, Glaring Fleshraker, or Eldrazi Linebreaker starts often enough to justify weak late draws and Null Rod tension?

- Lock density: is 4 Chalice of the Void correct across the observed field, or are too many games decided by drawing Chalice of the Void after the relevant cheap spells have already resolved?

- Threat curve: do 4 Eldrazi Linebreaker, 4 Glaring Fleshraker, 4 Thought-Knot Seer, 1 Reality Smasher, and 2 Sire of Seven Deaths create the right mix of speed, disruption, and closing power?

- Top-end tension: should Sire of Seven Deaths remain a two-copy closer if it is repeatedly stranded, or is it the exact card that wins after early disruption empties both players' resources?

- Modal spell confidence: are 4 Kozilek's Command and 1 Eldrazi Confluence producing enough Forge-confirmed interaction or selection to justify their slots? Card text check required before using mode assumptions as tuning evidence.

- Utility creature role: is Wastescape Battlemage functioning as a real interaction card, a body with occasional upside, or a stranded modal card? Card text check required for the exact problem it solves.

- Early setup role: is 3 It That Heralds the End improving the first threat or engine turn often enough, or does it conflict with keeping pressure dense and mulligans simple?

- Mana denial plan: should the registered 1 Wasteland main plus 3 Wasteland sideboard stay split this way if mana denial wins post-board games, or is the main deck losing Game 1s where one more Wasteland effect would matter?

- Graveyard plan: is 4 Leyline of the Void worth the sideboard space if graveyard opponents can pivot to fair games, or is the free opening hate exactly what the deck needs while still casting pressure?

- Artifact plan: is 2 Null Rod high impact enough despite conflict with Lotus Petal, and are pilots sequencing Lotus Petal before Null Rod only when the current legal line needs it?

- Named-hate plan: is 4 Disruptor Flute earning its quantity by stopping known payoffs or interaction, or does it dilute threat density in matchups where the opponent's decisive card is not visible?

- Defensive slot balance: are 1 Warping Wail and 1 Karn's Sylex solving the creature-race and emergency-board problems, or does the deck need sideboard space aimed at faster pressure instead? Card text check required for exact mode and reset assumptions.

- Role conflict: does post-board play become too reactive after adding Leyline of the Void, Disruptor Flute, Null Rod, Wasteland, Warping Wail, or Karn's Sylex? Keep asking whether the deck still ends games before opponents recover.

- Closing plan: if losses happen after early disruption succeeds, test whether the problem is too few closers, poor combat decisions, stranded mana, or overemphasis on lock pieces instead of Eldrazi pressure.

## Veles Tactical Policy

### Policy: Opening Keep Gate
Priority: High
Decision families: mulligan
Cards: Ancient Tomb; Eldrazi Temple; Eye of Ugin; Lotus Petal; Chalice of the Void; Thought-Knot Seer; Eldrazi Linebreaker; Glaring Fleshraker
Phase windows: pregame, mulligan
Runtime cues: prompt:mulligan; action:keep; action:mulligan
Use when: deciding whether the opener can produce a turn-one lock or turn-two threat from visible hand and legal mulligan actions.
Avoid when: the opener has no functional mana path, only Eye of Ugin as mana, or threats that cannot be cast before the opponent establishes tempo.
Instructions: Prefer hands with Ancient Tomb or Eldrazi Temple plus either Chalice of the Void, Thought-Knot Seer, Glaring Fleshraker, or Eldrazi Linebreaker. Treat Lotus Petal as acceleration, not a land replacement, unless it creates an immediate lock or pressure line.
Pilot skill floor: light-model
No-API allowed: no
Light-model allowed: yes

### Policy: Leyline Pregame Execution
Priority: Medium
Decision families: pregame
Cards: Leyline of the Void
Phase windows: pregame
Runtime cues: action:begin the game with Leyline of the Void
Use when: Leyline of the Void is in the opening hand after sideboarding and Forge offers the legal pregame placement action.
Avoid when: the action text does not name Leyline of the Void.
Instructions: Put Leyline of the Void onto the battlefield when the legal action explicitly offers it. This is deterministic after the sideboard plan selected Leyline of the Void for the matchup.
Pilot skill floor: no-api
No-API allowed: yes
Light-model allowed: yes

### Policy: First Lock Commitment
Priority: High
Decision families: priority; mana
Cards: Chalice of the Void; Lotus Petal; Ancient Tomb; Eldrazi Temple
Phase windows: opening turns, main phase priority
Runtime cues: action:cast Chalice of the Void; prompt:pay costs; prompt:choose value for X
Use when: choosing whether to spend early mana, Lotus Petal, or Ancient Tomb life on Chalice of the Void.
Avoid when: visible legal actions show a stronger immediate threat and the matchup or known hand makes Chalice of the Void low impact.
Instructions: Use reasoning for the Chalice number and timing. Favor early Chalice of the Void when it meaningfully constrains the opponent before they unload cheap spells, but do not let it replace a necessary clock against opponents already operating above the chosen number.
Pilot skill floor: light-model
No-API allowed: no
Light-model allowed: yes

### Policy: Chalice Number Resolution
Priority: Medium
Decision families: selection
Cards: Chalice of the Void
Phase windows: cast resolution, X selection
Runtime cues: action:choose X=1 for Chalice of the Void; action:choose X=0 for Chalice of the Void
Use when: a prior reasoning step has committed to casting Chalice of the Void and the legal action text contains the exact chosen X value.
Avoid when: multiple X values are legal and no prior policy or decision reason names the value.
Instructions: Select the exact X action named by the current chosen line. Do not infer a Chalice number from generic format assumptions alone.
Pilot skill floor: no-api
No-API allowed: no
Light-model allowed: yes

### Policy: Early Enabler Setup
Priority: Medium
Decision families: priority; mana
Cards: It That Heralds the End; Glaring Fleshraker; Eldrazi Linebreaker; Eldrazi Temple; Eye of Ugin
Phase windows: turns one through three, main phase priority
Runtime cues: action:cast It That Heralds the End; action:cast Glaring Fleshraker; action:cast Eldrazi Linebreaker
Use when: choosing the first permanent that unlocks pressure, cost reduction, or engine damage from visible legal actions.
Avoid when: the opponent has a visible board that requires immediate interaction or a known disruptive card from Thought-Knot Seer changes the race.
Instructions: Prioritize the first creature or engine that makes the next turn stronger, not merely the largest current body. Card text check required for It That Heralds the End and Glaring Fleshraker if Forge does not expose cost or trigger consequences.
Pilot skill floor: light-model
No-API allowed: no
Light-model allowed: yes

### Policy: Sol-Land Payment Discipline
Priority: Medium
Decision families: mana
Cards: Ancient Tomb; Eldrazi Temple; Eye of Ugin; Cavern of Souls; Petrified Hamlet; Abundant Countryside; Lotus Petal
Phase windows: all cost-payment prompts
Runtime cues: prompt:pay mana; action:activate Ancient Tomb; action:activate Eldrazi Temple; action:sacrifice Lotus Petal
Use when: multiple visible mana-payment actions can pay for the same spell or ability.
Avoid when: Forge presents only one legal payment route.
Instructions: Preserve Lotus Petal unless it creates an immediate lock, disruptive threat, or tempo-critical play. Use Ancient Tomb life deliberately when the extra mana changes the current turn; account for pressure and racing before taking avoidable damage.
Pilot skill floor: light-model
No-API allowed: no
Light-model allowed: yes

### Policy: Cavern Naming
Priority: Medium
Decision families: selection; mana
Cards: Cavern of Souls; Thought-Knot Seer; Reality Smasher; Sire of Seven Deaths; Glaring Fleshraker; Eldrazi Linebreaker; Wastescape Battlemage; It That Heralds the End
Phase windows: land-entry choice prompts
Runtime cues: action:choose Eldrazi; prompt:choose creature type
Use when: Cavern of Souls asks for a creature type and the deck's visible hand or board contains Eldrazi creature spells.
Avoid when: Forge action text does not expose the chosen type or another visible creature type is required for a currently legal spell.
Instructions: Choose Eldrazi when the legal action text offers that type. Route through reasoning if visible hand contains only uncertain non-Eldrazi creature types. Card text check required for exact creature types if Forge does not expose them.
Pilot skill floor: no-api
No-API allowed: yes
Light-model allowed: yes

### Policy: Thought-Knot Disruption Gate
Priority: High
Decision families: interaction; priority
Cards: Thought-Knot Seer
Phase windows: main phase priority, triggered hand-reveal choice
Runtime cues: action:cast Thought-Knot Seer; prompt:choose a nonland card; action:target opponent Thought-Knot Seer
Use when: deciding whether Thought-Knot Seer should take priority over pressure or lock pieces, or selecting from revealed hand.
Avoid when: opponent hand is not revealed for the choice, or the target/action text is ambiguous.
Instructions: Cast Thought-Knot Seer early when it removes a known payoff or answer while adding pressure. On the reveal choice, select the visible nonland card that most threatens the current line; do not assume hidden follow-up cards.
Pilot skill floor: light-model
No-API allowed: no
Light-model allowed: yes

### Policy: Target Opponent With Thought-Knot Seer
Priority: Low
Decision families: selection; interaction
Cards: Thought-Knot Seer
Phase windows: target-selection prompt
Runtime cues: action:target opponent Thought-Knot Seer
Use when: Forge offers a legal target action whose text explicitly targets opponent for Thought-Knot Seer.
Avoid when: multiple opponents exist or the action text does not contain opponent and Thought-Knot Seer.
Instructions: Choose the opponent-target action for Thought-Knot Seer in two-player games. The strategic hand-card selection remains a light-model decision after the reveal.
Pilot skill floor: no-api
No-API allowed: yes
Light-model allowed: yes

### Policy: Wasteland Commitment
Priority: Medium
Decision families: interaction; mana
Cards: Wasteland
Phase windows: main phase, opponent end step when legal
Runtime cues: action:activate Wasteland; action:target land
Use when: deciding whether to spend Wasteland on a visible nonbasic land.
Avoid when: using Wasteland would delay a current threat or leave no pressure after mana denial.
Instructions: Use Wasteland when the visible target is central to the opponent's next legal development or cuts them off a known color/resource. Keep mana denial paired with a clock; do not trade land drops if the opponent is already ahead on board and the deck needs to cast creatures.
Pilot skill floor: light-model
No-API allowed: no
Light-model allowed: yes

### Policy: Modal Spell Commitment
Priority: Medium
Decision families: interaction; selection; priority
Cards: Kozilek's Command; Eldrazi Confluence; Wastescape Battlemage; Warping Wail; Karn's Sylex
Phase windows: main phase, combat windows, stack interaction windows
Runtime cues: action:cast Kozilek's Command; action:cast Eldrazi Confluence; action:cast Wastescape Battlemage; action:cast Warping Wail; action:activate Karn's Sylex
Use when: modal or flexible interaction is legal and the choice changes removal, selection, board control, or tempo.
Avoid when: card text or mode text is hidden from the prompt.
Instructions: Route modal choices through reasoning. Choose modes from visible threats, stack objects, and race math only; Card text check required for any mode whose exact Forge text is not shown.
Pilot skill floor: light-model
No-API allowed: no
Light-model allowed: yes

### Policy: Fleshraker Pressure Engine
Priority: Medium
Decision families: priority; combat
Cards: Glaring Fleshraker; Kozilek's Command; Lotus Petal; Chalice of the Void; Eldrazi Linebreaker; Thought-Knot Seer
Phase windows: main phase priority, attack step
Runtime cues: action:cast Glaring Fleshraker; trigger:Glaring Fleshraker; action:cast colorless
Use when: choosing whether to sequence Glaring Fleshraker before other colorless spells.
Avoid when: a lock or disruption play must happen first to prevent a visible loss or known answer.
Instructions: Prefer Glaring Fleshraker before chains of colorless spells when the legal sequence can produce extra pressure. Card text check required if Forge does not show the trigger result; never assume lethal trigger damage without engine output.
Pilot skill floor: light-model
No-API allowed: no
Light-model allowed: yes

### Policy: Top-End Commitment
Priority: Medium
Decision families: priority; combat; mana
Cards: Reality Smasher; Sire of Seven Deaths; Ancient Tomb; Eldrazi Temple; Eye of Ugin
Phase windows: main phase priority, precombat main phase
Runtime cues: action:cast Reality Smasher; action:cast Sire of Seven Deaths
Use when: deciding whether to tap out for the large threat rather than cast multiple smaller plays.
Avoid when: visible interaction, known hand information, or board state rewards spreading threats instead.
Instructions: Commit Reality Smasher or Sire of Seven Deaths when the resulting clock or stabilization is worth the mana concentration. Treat Sire of Seven Deaths text as conditional unless Forge exposes the combat and protection abilities.
Pilot skill floor: light-model
No-API allowed: no
Light-model allowed: yes

### Policy: Attack Discipline
Priority: Medium
Decision families: combat
Cards: Eldrazi Linebreaker; Glaring Fleshraker; Thought-Knot Seer; Reality Smasher; Sire of Seven Deaths; Wastescape Battlemage; It That Heralds the End
Phase windows: declare attackers
Runtime cues: prompt:declare attackers; action:attack with
Use when: choosing attackers from visible creatures and board state.
Avoid when: exactly lethal is not visible, blockers or tricks could change the race, or the creature is needed to block a visible counterattack.
Instructions: Attack when pressure advances a faster clock without sacrificing necessary defense. Keep Thought-Knot Seer and high-power Eldrazi aggressive against empty or weak boards; hold creatures back when blocking prevents a visible lethal or near-lethal swing.
Pilot skill floor: light-model
No-API allowed: no
Light-model allowed: yes

### Policy: Exact Lethal Attack
Priority: High
Decision families: combat
Cards: Eldrazi Linebreaker; Glaring Fleshraker; Thought-Knot Seer; Reality Smasher; Sire of Seven Deaths; Wastescape Battlemage; It That Heralds the End
Phase windows: declare attackers
Runtime cues: action:attack with all creatures
Use when: visible attackers' current power is greater than or equal to opponent life, opponent has no visible blockers, and Forge offers exactly one attack action containing all creatures.
Avoid when: any visible blocker, prevention effect, combat restriction, or multiple attack configurations are legal.
Instructions: Choose the all-creatures attack action only under the visible no-blocker lethal condition. Do not use this policy for normal race decisions.
Pilot skill floor: no-api
No-API allowed: yes
Light-model allowed: yes

### Policy: Blocking Survival Gate
Priority: High
Decision families: combat
Cards: Eldrazi Linebreaker; Glaring Fleshraker; Thought-Knot Seer; Reality Smasher; Sire of Seven Deaths; Wastescape Battlemage; It That Heralds the End
Phase windows: declare blockers, combat damage assignment
Runtime cues: prompt:declare blockers; action:block
Use when: visible attackers threaten lethal or a short clock and blockers are legal.
Avoid when: the opponent's lethal depends on hidden cards not represented by legal actions or public board state.
Instructions: Block to survive first, then preserve the strongest counterattack. Route trades, double blocks, and damage assignment through reasoning because creature abilities and follow-up tricks can change outcomes.
Pilot skill floor: light-model
No-API allowed: no
Light-model allowed: yes

### Policy: Sideboard Lock-Hate Selection
Priority: High
Decision families: sideboard
Cards: Leyline of the Void; Null Rod; Disruptor Flute; Wasteland; Warping Wail; Karn's Sylex; Chalice of the Void; Lotus Petal
Phase windows: between games
Runtime cues: prompt:sideboard; action:submit sideboard plan
Use when: selecting a legal post-board plan from registered sideboard cards.
Avoid when: a proposed plan names cards outside the registered sideboard or cuts more main-deck copies than registered.
Instructions: Add Leyline of the Void against graveyard-centric opponents, Null Rod against artifact-dependent opponents despite Lotus Petal tension, Disruptor Flute against known named payoffs or interaction, Wasteland for mana denial, Warping Wail for narrow interaction, and Karn's Sylex for emergency board control. Keep enough threats to end the game after hate resolves.
Pilot skill floor: light-model
No-API allowed: no
Light-model allowed: yes

### Policy: Null Rod Sequencing
Priority: Medium
Decision families: priority; mana; sideboard
Cards: Null Rod; Lotus Petal
Phase windows: post-board main phase priority
Runtime cues: action:cast Null Rod; action:sacrifice Lotus Petal
Use when: Null Rod and Lotus Petal are both visible or legally usable.
Avoid when: Lotus Petal is not needed for the current turn and Null Rod is not yet strategically selected.
Instructions: Spend Lotus Petal before Null Rod only when the mana is required for the current legal play. Do not delay Null Rod merely to preserve speculative future Lotus Petal use if the opponent's artifact engine is the visible threat.
Pilot skill floor: light-model
No-API allowed: no
Light-model allowed: yes

### Policy: Disruptor Flute Naming Gate
Priority: Medium
Decision families: interaction; selection; sideboard
Cards: Disruptor Flute; Thought-Knot Seer
Phase windows: post-board priority, name-selection prompt
Runtime cues: action:cast Disruptor Flute; prompt:choose card name
Use when: choosing whether to cast Disruptor Flute or name a card from public information or revealed hand.
Avoid when: no relevant card name is known from public zones, Thought-Knot Seer reveal, matchup guide, or visible stack pressure.
Instructions: Name the card that public information identifies as the opponent's immediate payoff, answer, or engine piece. Do not invent hidden cards; use matchup context only as archetype-level guidance when no revealed card is available.
