# Strategy Specifications
## Deck Name And Archetype
The Rock is a Modern black-green sacrifice-midrange deck, not a generic pile of format staples. Treat the supplied tags `midrange, discard, midrange,discard` as normalized tags `midrange` and `discard`, with sacrifice, recursion, and artifact-token pressure as deck-specific subthemes. The submitted maindeck validates to 60 cards, and the submitted sideboard validates to 15 cards. The deck also respects normal copy-count structure: no nonbasic or non-basic-spell line exceeds four copies, and only `Swamp` appears as a basic land.

- Format validation: Use `modern` as the format label, but recheck current Modern legality and the active banned-and-restricted list before sanctioned or engine-authoritative testing. No card should be assumed legal merely because it appears in the imported list.
- Name validation: Use the registered decklist names exactly in this guide. The local card cache recognizes `Sephiroth, Fabled SOLDIER` as the front face of `Sephiroth, Fabled SOLDIER // Sephiroth, One-Winged Angel`; Veles deck import should confirm whether the runtime engine accepts the submitted front-face name or requires the full double-faced oracle name.
- Stock status: Classify this as hybrid stock/rogue. The shell is recognizable as The Rock because it plays black-green attrition, discard, removal-adjacent interaction, and resilient threats, but this exact build is highly deck-specific around `Marionette Apprentice`, `Warren Soultrader`, `Gravecrawler`, `Shambling Ghast`, `Phyrexian Tower`, `Chthonian Nightmare`, `Phoenix Fleet Airship`, and `Spymaster's Vault`.
- Role identity: Start games as a disruptive sacrifice-midrange deck that converts early creatures into mana, material, drain, or recursive pressure. Do not pilot it as pure control; the maindeck has `Thoughtseize`, `Flare of Malice`, and `Orcish Bowmasters`, but it does not contain a broad maindeck removal suite.
- Mana identity: Treat black as the primary color and green as a required splash for `Malevolent Rumble` and sideboard `Culling Ritual`. The land base is 21 lands, with `Marsh Flats`, `Verdant Catacombs`, `Polluted Delta`, `Bloodstained Mire`, `Overgrown Tomb`, and `Underground Mortuary` enabling black-green access, while `Phyrexian Tower` is powerful but conditional because it needs creatures to convert into extra black mana.
- Curve concern: Prioritize hands that can operate before turn three because the deck's best starts use one-mana discard or recursive/sacrifice bodies into two-mana engines. Hands with only `Phoenix Fleet Airship`, `Sephiroth, Fabled SOLDIER`, or clunky sideboard spells need strong mana and early interaction before they are keepable.
- Legality concern: `Phoenix Fleet Airship`, `Sephiroth, Fabled SOLDIER`, and other newer cards need card-text and legality confirmation in the engine environment before automated playtesting. If the rules engine exposes unexpected text, use the engine output over this guide.
- Opponent info status: No opponent decklist, archetype, or metagame target was supplied for this batch. Matchup policies must therefore be written later as conditional guidance from visible battlefield, graveyard, exile, hand-reveal, stack, life total, and legal-action information, not from guessed hidden cards.
- Runtime principle: Veles must follow legal actions first, visible board state second, and this deck guide third. This specification may recommend a role, but it must never override the rules engine, invent hidden information, or assume an action exists when Veles did not enumerate it.

## Thesis
The Rock assembles a recursive sacrifice-midrange engine, then wins by turning cheap creatures into mana, attrition, drain, artifact pressure, and repeatable board presence. Prioritize hands and lines that put an expendable body on the battlefield, establish a sacrifice outlet or recursion engine, and keep the opponent from executing their highest-impact early spell with `Thoughtseize`, `Orcish Bowmasters`, `Flare of Malice`, or sideboard interaction.

The primary game plan is to trade early resources, keep material flowing, and make every creature death matter. `Gravecrawler`, `Shambling Ghast`, `Marionette Apprentice`, `Warren Soultrader`, `Phyrexian Tower`, and `Chthonian Nightmare` are the deck's core texture: a body is rarely just a body if it can become mana, a trigger, a recast, a sacrifice payment, or a returned threat. Do not preserve expendable creatures by default; preserve the engine role they currently supply.

The deck wins when recursive creatures and artifact/death payoffs convert a stalled battlefield into inevitability. `Marionette Apprentice` and `Orcish Bowmasters` punish small exchanges, `Phoenix Fleet Airship` and `Sephiroth, Fabled SOLDIER` represent higher-end pressure if the runtime text confirms their role, and `Spymaster's Vault` can turn creature deaths or artifacts into longer-game card advantage if the visible board supports it. Card text check required for `Phoenix Fleet Airship`, `Sephiroth, Fabled SOLDIER`, and exact `Spymaster's Vault` timing before treating any of them as a deterministic payoff.

The deck is not trying to be pure control, pure combo, or all-in graveyard recursion. Do not spend `Thoughtseize` or `Flare of Malice` merely to trade one-for-one when the visible board shows a faster route to engine dominance, but do not ignore a must-answer stack or permanent just because the sacrifice engine is online. The correct posture is usually pressure plus disruption: force the opponent to answer recursive threats while their best stabilizer, sweeper, combo piece, or hate card is delayed.

Prioritize black mana, sacrifice density, and visible legality over abstract curve ideals. `Phyrexian Tower` is powerful when creatures are available and weak when the hand lacks bodies; fetchlands should normally secure black first while preserving green access for `Malevolent Rumble`, `Underground Mortuary`, and post-board `Culling Ritual`. Use the rules engine's legal actions for all sacrifice, recursion, cast-from-graveyard, and optional-payment choices; this guide should never assume a loop is available unless Veles exposes the exact action.

## Role Package
- Threats: `Gravecrawler`, `Orcish Bowmasters`, `Marionette Apprentice`, `Warren Soultrader`, `Phoenix Fleet Airship`, and `Sephiroth, Fabled SOLDIER` are the cards most likely to convert time into damage or board pressure. Treat `Gravecrawler` as a recursive threat when a legal Zombie condition exists, `Orcish Bowmasters` as both pressure and punishment for draw-heavy lines, and the higher-cost threats as commitment decisions that require checking visible mana, opponent pressure, and available interaction.

- Payoffs: `Marionette Apprentice`, `Spymaster's Vault`, `Phoenix Fleet Airship`, and `Sephiroth, Fabled SOLDIER` are the payoff module, but their exact runtime value depends on engine text and board state. Use `Marionette Apprentice` as the clearest sacrifice/death payoff; use `Spymaster's Vault` only when creature deaths or artifact resources can be converted without sacrificing immediate survival; apply Card text check required to `Phoenix Fleet Airship` and `Sephiroth, Fabled SOLDIER` before relying on specific combat, transform, or damage math.

- Engines: `Warren Soultrader`, `Chthonian Nightmare`, `Phyrexian Tower`, `Gravecrawler`, `Shambling Ghast`, and `Marionette Apprentice` are the main engine pieces. Favor lines that pair an expendable creature with a sacrifice outlet, then convert the death into mana, recursion, or drain. When multiple engines are legal, protect the engine that creates repeated actions across turns over the engine that only creates one immediate exchange.

- Velocity: `Malevolent Rumble`, `Marsh Flats`, `Verdant Catacombs`, `Polluted Delta`, `Bloodstained Mire`, and recursive graveyard access provide selection and smoothing. Use `Malevolent Rumble` to find permanent-based engine pieces or stabilize mana when the hand has time; avoid spending early green velocity if the visible board demands discard, a creature, or interaction first.

- Interaction: `Thoughtseize`, `Flare of Malice`, `Orcish Bowmasters`, sideboard `Fatal Push`, sideboard `Culling Ritual`, sideboard `Break the Ice`, sideboard `Shatter Assumptions`, sideboard `Vexing Bauble`, sideboard `Nihil Spellbomb`, and sideboard `Ashiok, Dream Render` are the interactive package. Use maindeck interaction to clear the opponent's highest-impact visible or revealed plan, not to maximize card-count trades in isolation.

- Protection: `Thoughtseize`, `Flare of Malice`, `Orcish Bowmasters`, and `Vexing Bauble` function as protection by disrupting answers before or during key turns. Protect `Warren Soultrader`, `Marionette Apprentice`, `Chthonian Nightmare`, or a high-end threat when losing that card would collapse the current line; otherwise spend protection to prevent the opponent's most immediate winning line.

- Recursion: `Gravecrawler` and `Chthonian Nightmare` are the recursion module, with `Warren Soultrader` and `Phyrexian Tower` supplying sacrifice pressure that can make recursion profitable. Keep at least one relevant creature type or return target in mind, but never assume hidden or future graveyard access; act only from the battlefield, graveyard, hand, and legal-action text Veles exposes.

- Mana: `Swamp`, `Overgrown Tomb`, `Underground Mortuary`, `Marsh Flats`, `Verdant Catacombs`, `Polluted Delta`, `Bloodstained Mire`, and `Phyrexian Tower` form a black-first mana base with a green splash. Fetch black sources early, preserve green when `Malevolent Rumble` or `Culling Ritual` matters, and treat `Phyrexian Tower` as an engine land rather than a normal untapped black source when no expendable creature is present.

- Sideboard modules: `Fatal Push` covers creature pressure, `Nihil Spellbomb` and `Ashiok, Dream Render` cover graveyard or search pressure, `Vexing Bauble` covers free-spell or alternate-cast pressure when its runtime text matches the matchup, `Culling Ritual` covers low-cost permanent swarms, `Break the Ice` covers vulnerable mana bases, and `Shatter Assumptions` covers hand or spell patterns only after Card text check required confirms the effect.

## Primary Win Conditions
- Combo drain with `Warren Soultrader`, `Gravecrawler`, and `Marionette Apprentice` is the highest-ceiling win path. Setup requires `Warren Soultrader` on the battlefield, `Gravecrawler` castable from the graveyard by visible legal action, and `Marionette Apprentice` or another confirmed death/artifact payoff present. Execution is to sacrifice `Gravecrawler` to `Warren Soultrader`, convert the generated resource into recasting `Gravecrawler`, and repeat only while the rules engine exposes each sacrifice and recast as legal. Disruption to respect includes removal on `Warren Soultrader` or `Marionette Apprentice`, graveyard hate, life-total constraints from repeated payments, and any visible stack interaction. Prioritize this path when the opponent is tapped low, when `Thoughtseize` has cleared the relevant answer, when the battlefield is stalled, or when waiting gives the opponent a faster kill.

- Recursive attrition with `Gravecrawler`, `Chthonian Nightmare`, `Phyrexian Tower`, and expendable bodies is the default fair win path. Setup is a battlefield with creatures that can be sacrificed profitably, graveyard access that Veles confirms, and enough black mana to keep redeploying pressure. Execution is to trade resources, recur threats, and make each death advance mana, cards, or damage through `Marionette Apprentice` and repeated attacks. Disruption to respect includes exile effects, graveyard shutdown, sweepers that remove the supporting creature type, and removal aimed at the sacrifice outlet rather than the recursive body. Prioritize this line when the opponent has interaction for a single combo turn but cannot beat repeated small exchanges.

- Discard-backed pressure with `Thoughtseize`, `Orcish Bowmasters`, `Marionette Apprentice`, and `Shambling Ghast` wins by forcing awkward trades. Setup is an early threat plus discard that identifies whether the opponent's hand is threat-heavy, answer-heavy, or combo-heavy. Execution is to take the card that beats the current board, then attack and sacrifice in ways that keep damage flowing while denying the opponent a clean stabilizing turn. Disruption to respect includes large blockers, lifegain, sweepers, and card-advantage engines that ignore one-for-one discard. Prioritize this path when the opening hand lacks `Warren Soultrader` or recursion but has early black mana and multiple proactive plays.

- High-end pressure from `Phoenix Fleet Airship`, `Sephiroth, Fabled SOLDIER`, and `Spymaster's Vault` is a commitment win path, not a default curve-out assumption. Card text check required for exact combat, trigger, artifact, and card-advantage roles before treating these cards as deterministic finishers. Setup is stable mana, a board that can protect or exploit the permanent, and enough prior disruption that tapping out does not lose immediately. Prioritize this path when the engine pieces are missing, the opponent has exhausted removal, or the visible board demands a larger threat than repeated one-power attacks.

## Secondary Win Conditions
- `Orcish Bowmasters` can become a standalone kill when the opponent draws extra cards or when its token pressure survives. Use it as interaction first if the opponent presents a draw trigger or small creature, but pivot to damage when the token and body create a real clock. Do not assume the opponent will draw extra hidden cards; respond only to visible legal triggers, stack objects, and public effects.

- `Phyrexian Tower` converts small creatures into tempo wins when the hand contains expensive pressure or multiple spells. Sacrifice `Shambling Ghast`, disposable tokens, or recursive `Gravecrawler` when the resulting mana unlocks a decisive spell, recursion chain, or double-spell turn. Avoid sacrificing the only creature that enables `Gravecrawler` unless the legal action wins, stabilizes, or protects a more important engine.

- `Malevolent Rumble` supports secondary wins by finding permanents and stocking resources, but it is not a win condition by itself. Use it when the game is about assembling `Warren Soultrader`, `Marionette Apprentice`, `Chthonian Nightmare`, `Spymaster's Vault`, or mana stability. Defer it when the visible board requires `Thoughtseize`, `Flare of Malice`, a blocker, or a sacrifice line this turn.

- `Flare of Malice` can enable a pressure win by answering the permanent or creature that stops combat or combo execution. Use sacrifice-assisted casting only when the sacrificed creature is expendable or recursive, and when removing the target meaningfully changes the race, protects the engine, or prevents the opponent's lethal line. Do not spend it on a medium threat if the opponent's revealed hand or board contains a higher-impact target.

## Emergency Lines
- When behind on life, stop treating the `Warren Soultrader` loop as automatic. Count visible life totals and only pay life if the line wins, prevents lethal, or creates a board state that survives the opponent's next known attack. Prefer blocking, `Flare of Malice`, `Fatal Push` after sideboard, or a stabilizing sacrifice line over speculative recursion.

- When behind on board, preserve bodies that block unless sacrificing them produces immediate removal, mana for a stabilizer, or confirmed lethal pressure. `Shambling Ghast` and `Gravecrawler` are acceptable emergency resources, but do not expose yourself to lethal attacks just to maintain engine texture.

- When behind on cards, turn every recursive legal action into material. Favor `Chthonian Nightmare`, `Gravecrawler`, `Malevolent Rumble`, and `Spymaster's Vault` when their text and legality support recouping resources. Avoid trading `Thoughtseize` for a low-impact card if life is low and the opponent's visible board is already the problem.

- When behind on mana, use fetchlands to secure black first and green only when the hand needs `Malevolent Rumble` or sideboard `Culling Ritual`. Treat `Phyrexian Tower` as recovery if a sacrificial creature is available, but do not keep a hand or sequence that requires it to function without creatures.

- When graveyard recursion is shut off, become a discard-removal midrange deck. Cast threats from hand, pressure with `Orcish Bowmasters` and `Marionette Apprentice`, use `Thoughtseize` to clear the most relevant answer, and wait for Veles to expose a legal window before trying graveyard actions again.

- When win conditions are removed, win through small-board inevitability instead of forcing absent loops. Attack with surviving creatures, use `Phoenix Fleet Airship` or `Sephiroth, Fabled SOLDIER` only after Card text check required, and convert sacrifice fodder into removal, mana, or damage only when the current legal action advances survival or a real clock.

## Resource Model
- Life is a spendable resource only while the visible clock allows it. `Thoughtseize`, fetchlands into `Overgrown Tomb`, and legal life-payment actions from `Warren Soultrader` can buy information, mana, or engine progress, but stop paying life when the opponent's public battlefield threatens lethal or a two-turn clock. Treat every life payment as a tempo purchase that must either protect the engine, unlock a decisive turn, or remove a card that beats the current board.

- Hand size is strongest when it contains a discard spell, a cheap body, and a payoff or selection piece. `Thoughtseize` converts one card and 2 life into information plus disruption; use that information to decide whether to protect `Warren Soultrader`, remove a threat with `Flare of Malice`, or spend the turn developing `Malevolent Rumble`. Avoid emptying the hand into unknown sweepers unless discard or public information shows the coast is clear.

- Mana is the deck's main conversion engine, not just a casting constraint. `Phyrexian Tower` turns expendable creatures into black acceleration, `Warren Soultrader` may convert creature deaths and life into mana when Veles exposes those legal actions, and fetchlands fix the green splash. Use burst mana to double-spell, cast expensive pressure, or restart recursion; do not sacrifice the only enabling creature for mana unless the resulting legal action is worth losing that board function.

- Board presence is both pressure and fuel. `Gravecrawler`, `Shambling Ghast`, `Marionette Apprentice`, Orc Army tokens from `Orcish Bowmasters`, and other expendable bodies can attack, block, be sacrificed, or support recursion. Preserve at least one creature when it keeps `Gravecrawler` lines live or protects against attacks; cash creatures in when `Marionette Apprentice`, `Flare of Malice`, `Phyrexian Tower`, or `Chthonian Nightmare` turns the sacrifice into immediate material.

- Graveyard access is a live resource only when the rules engine exposes legal actions. `Gravecrawler` and `Chthonian Nightmare` make deaths valuable, and `Malevolent Rumble` can help stock or select resources, but do not assume a card in graveyard is usable through public hate, timing limits, or missing creature-type requirements. If the opponent presents graveyard pressure, sideboard bullets such as `Nihil Spellbomb` and `Ashiok, Dream Render` change the game into a resource-denial fight.

- Exile is usually a warning zone for this deck. Cards exiled by opponent effects are no longer recursion resources unless Veles shows a legal permission to use them. Sideboard `Nihil Spellbomb` and `Ashiok, Dream Render` use exile as opponent-resource denial; deploy them when the matchup or visible graveyard makes exile materially better than adding another small attacker.

- Information converts into sequencing equity. `Thoughtseize` should identify whether the opponent can stop the engine, race, sweep the board, or exploit the graveyard. Use revealed cards to choose whether sideboard bullets like `Vexing Bauble`, `Fatal Push`, `Culling Ritual`, `Break the Ice`, `Shatter Assumptions`, `Nihil Spellbomb`, or `Ashiok, Dream Render` should be prioritized in post-board games.

## Mana Guide
- Keep hands that cast early black spells without relying on a creature surviving. A functional opener usually has black mana for `Thoughtseize`, `Gravecrawler`, `Shambling Ghast`, `Orcish Bowmasters`, or `Marionette Apprentice`, plus a path to green if it contains `Malevolent Rumble` or post-board `Culling Ritual`. Mulligan hands where `Phyrexian Tower` is the only mana source unless the rest of the hand and legal deck rules make that risk unavoidable.

- Fetch black first unless green is required this turn. `Marsh Flats`, `Verdant Catacombs`, `Polluted Delta`, and `Bloodstained Mire` should usually secure `Swamp` or `Overgrown Tomb` based on life pressure and color needs. Fetch `Overgrown Tomb` untapped only when the green spell or double-spell turn is worth the life; otherwise use basic `Swamp` to preserve life against pressure.

- Sequence tapped and utility lands around action density. `Underground Mortuary` is valuable fixing but should enter on turns where the hand can afford a tapped land or where its surveil-like text is confirmed by Veles and useful. `Phyrexian Tower` is powerful but color-narrow; play it when black burst mana matters, when sacrifice fodder is available, or when another land already covers normal casting.

- Play lands before drawing or selecting when the current turn needs mana for known legal actions. Make the land drop first before `Malevolent Rumble`, `Spymaster's Vault`, or other selection if spending the mana this turn is already required. Delay the land drop only when a visible selection effect can change which land is correct, when fetch timing preserves information, or when landfall/revolt-style opponent context makes timing matter; Card text check required for any card-specific trigger not shown by Veles.

- Use `Phyrexian Tower` sacrifice mana for decisive turns, not routine convenience. Best fuel is `Shambling Ghast`, recursive `Gravecrawler`, expendable tokens, or a body already losing value. Avoid sacrificing `Warren Soultrader`, `Marionette Apprentice`, or the only creature enabling recursion unless the resulting spell or ability removes lethal, wins, or protects the primary engine.

- Respect post-board color strain. `Fatal Push`, `Nihil Spellbomb`, `Vexing Bauble`, `Shatter Assumptions`, and `Break the Ice` are easier to cast than `Culling Ritual`; prioritize early black and artifact interaction while ensuring a green source before planning a `Culling Ritual` turn. Do not keep a sideboard hand that answers the matchup only if it draws green later unless the rest of the hand is already functional.

## Mulligan Guide
- Strong keep: keep `Swamp`, fetchland, `Thoughtseize`, `Gravecrawler`, `Marionette Apprentice`, `Warren Soultrader`, and any third land or `Malevolent Rumble`. This hand has turn-one information or board, turn-two drain/fodder setup, and a turn-three engine that can convert deaths into mana or pressure if the rules engine exposes those legal actions.

- Strong keep: keep two black lands, `Shambling Ghast`, `Orcish Bowmasters`, `Flare of Malice`, `Malevolent Rumble`, and one engine or payoff card. This hand can trade early, punish draw effects at instant speed, and use `Flare of Malice` only when sacrificing a black creature is worth the visible removal action.

- Medium keep: keep two lands with black mana, `Marionette Apprentice`, `Malevolent Rumble`, `Phoenix Fleet Airship`, and one sacrifice or discard piece. This hand is slower but functional; Card text check required for `Phoenix Fleet Airship`, so treat it as a payoff only when Veles shows castable, impactful legal actions.

- Risky keep: keep one-land fetchland hands only with `Thoughtseize` plus multiple one-mana creatures or `Malevolent Rumble` if the fetch can get the needed color and the matchup is not punishing stumble. Ship one-land `Phyrexian Tower` hands unless another land is present, because `Phyrexian Tower` needs creatures to become full mana.

- Automatic ship: ship hands with no black source, hands with only `Phyrexian Tower` as mana, hands with expensive cards and no one- or two-mana play, and hands that depend on `Warren Soultrader` surviving without a castable creature first. Ship hands where `Malevolent Rumble` is the only early play and no green source is available.

- Matchup-dependent keep: keep discard-heavy hands with `Thoughtseize` against combo, control, or unknown opponents on the play, but prefer creature/removal density against visible fast creature decks. Post-board, keep hands with `Fatal Push` against creature pressure, `Vexing Bauble` against free-spell decks, `Nihil Spellbomb` or `Ashiok, Dream Render` against graveyard/search reliance, and `Culling Ritual` only with green access and a board where it is likely to matter.

- Play/draw adjustment: on the play, prioritize `Thoughtseize` plus proactive creature sequencing because early information protects the engine. On the draw, prioritize a cheap battlefield play or `Fatal Push` post-board over speculative selection, because falling behind makes life payments from `Thoughtseize`, fetches, and `Warren Soultrader` more dangerous.

- Trap hand: avoid land-heavy hands with `Spymaster's Vault`, `Phoenix Fleet Airship`, `Sephiroth, Fabled SOLDIER`, and no early creature or discard. Card text check required for `Spymaster's Vault`, `Phoenix Fleet Airship`, and `Sephiroth, Fabled SOLDIER`; do not keep them as standalone plans without legal early development.

## Turn Arc
- Turn 1: lead with `Thoughtseize` when the matchup is unknown, the opponent has likely interaction, or the hand needs to know whether `Warren Soultrader` is safe. Lead with `Gravecrawler` or `Shambling Ghast` when pressure, sacrifice fuel, or blocking matters more than information; fetch `Swamp` unless `Malevolent Rumble` or sideboard `Culling Ritual` makes `Overgrown Tomb` necessary.

- Turn 1 deviation: play `Underground Mortuary` tapped only when no turn-one spell is available or the hand can afford a tempo pause. Play `Phyrexian Tower` early only with another mana source already present or with a creature curve that can exploit it next turn.

- Turn 2: prefer `Marionette Apprentice`, `Orcish Bowmasters`, or `Malevolent Rumble` based on visible pressure. Cast `Orcish Bowmasters` at instant speed when Veles shows a legal draw-punish or removal-like target; otherwise use `Marionette Apprentice` to make future sacrifices matter, or `Malevolent Rumble` to find land, engine, or pressure when the hand lacks direction.

- Turn 2 deviation: hold `Flare of Malice` unless the visible creature or planeswalker materially changes the race or threatens the engine. Do not sacrifice the only creature enabling `Gravecrawler` or future `Phyrexian Tower` mana unless the legal removal action prevents a worse loss.

- Turn 3: deploy `Warren Soultrader` when a creature is already present and the opponent's revealed or public resources do not make immediate removal disastrous. If information is missing, use `Thoughtseize` first when legal, then commit the engine only if the remaining mana and board support it.

- Turn 3 deviation: cast `Chthonian Nightmare` only when the graveyard, battlefield, and legal action text show an actual recursion or sacrifice exchange. If graveyard access is weak or hate is public, prefer `Phoenix Fleet Airship`, `Orcish Bowmasters`, or removal/selection instead; Card text check required for exact `Phoenix Fleet Airship` role.

- Turns 4-5: convert resources into a decisive board or attrition lock. Use `Phyrexian Tower`, `Warren Soultrader`, recursive `Gravecrawler`, `Shambling Ghast`, and `Marionette Apprentice` to double-spell, remove blockers, drain, or rebuild, but keep enough material to survive the opponent's next attack.

- Turns 4-5 deviation: tap out for `Sephiroth, Fabled SOLDIER`, `Phoenix Fleet Airship`, or a major `Chthonian Nightmare` turn only after checking visible interaction, known hand information, and whether waiting gives the opponent a better window. Card text check required for `Sephiroth, Fabled SOLDIER`; treat it as a high-commitment payoff only when Veles shows legal impact.

- Late game: prioritize recursive threats, sacrifice payoffs, and information-backed action chains over isolated attacks. Use `Gravecrawler` loops, `Chthonian Nightmare`, `Spymaster's Vault`, and excess bodies only through legal actions shown by Veles; convert lands and creatures into cards, mana, damage, or removal when that line improves the current board.

- Late-game deviation: protect life total before engine greed when the opponent has a visible two-turn clock or lethal setup. Stop paying life for `Thoughtseize`, fetch-shock lines, or `Warren Soultrader` unless the action removes lethal, creates lethal, or produces a clearly necessary defensive sequence.

## Card Roles
- `Thoughtseize`: Use `Thoughtseize` as the cleanest turn-one information and disruption play when the opponent's hand matters more than immediate board presence. Prioritize taking the card that stops `Warren Soultrader`, invalidates recursion, races your life total, or prevents a near-term engine turn; do not spend life on late `Thoughtseize` unless Veles shows a legal target and the exchange changes lethal, combo prevention, or a protected commitment. Against unknown opponents, cast it early before exposing `Warren Soultrader`, `Chthonian Nightmare`, or a high-value `Phoenix Fleet Airship` line.

- `Gravecrawler`: Treat `Gravecrawler` as recursive pressure and sacrifice fuel, not just a one-mana attacker. Preserve access to another Zombie when possible so future legal recast actions stay live; `Shambling Ghast` is not a Zombie unless rules output says otherwise, so do not assume it enables `Gravecrawler`. Use `Gravecrawler` aggressively with `Warren Soultrader`, `Phyrexian Tower`, `Marionette Apprentice`, and `Chthonian Nightmare` only when the visible board supports recasting or the sacrifice buys tempo, drain, mana, or survival.

- `Shambling Ghast`: Use `Shambling Ghast` as early defense, sacrifice material, and a death-trigger utility piece. Block early creature pressure with it when the death trigger can trade up, make mana, or shrink a key attacker according to legal choices. Do not cash it in automatically; it may be the body that turns on `Phyrexian Tower`, protects life total, or gives `Flare of Malice` an acceptable alternate-cost payment.

- `Marionette Apprentice`: Deploy `Marionette Apprentice` before sacrifice-heavy turns when possible because it turns routine deaths into pressure and leaves extra material behind. It is strongest with `Warren Soultrader`, `Phyrexian Tower`, `Shambling Ghast`, `Gravecrawler`, and `Chthonian Nightmare`, where bodies can be converted into mana, recursion, and drain-like pressure. Avoid attacking or sacrificing it casually if it is the only payoff making a loop or attrition turn meaningful.

- `Orcish Bowmasters`: Hold `Orcish Bowmasters` when the opponent is likely to draw extra cards, has one-toughness creatures, or is presenting a planeswalker or combat math target that can be punished at instant speed. Cast it proactively only when a body and Army token materially improve sacrifice density, pressure, or defense. In matchups with visible small creatures, treat it as removal plus board development; in slower matchups, treat it as a flash threat that punishes cantrips, draw spells, and end-step shields-down moments.

- `Warren Soultrader`: Treat `Warren Soultrader` as the main engine commitment and check removal exposure before casting it. It converts creatures into mana and card-flow pressure only if there is fodder, a payoff, or a follow-up spell; a naked `Warren Soultrader` into open interaction is often worse than developing `Marionette Apprentice`, casting `Malevolent Rumble`, or using `Thoughtseize` first. When it survives, sequence sacrifices so recursive `Gravecrawler`, expendable tokens, and `Shambling Ghast` are used before irreplaceable payoffs unless lethal or survival requires the opposite.

- `Malevolent Rumble`: Use `Malevolent Rumble` as early selection that fills the graveyard, finds material, and helps assemble engine pieces. Cast it when the hand lacks land, fodder, or a payoff, or when graveyard setup improves `Chthonian Nightmare` and `Gravecrawler` lines. Do not cast it blindly under pressure if a legal creature, removal spell, or discard play is needed to avoid falling behind; selection is strongest when the current turn can afford tempo.

- `Flare of Malice`: Use `Flare of Malice` as premium interaction, especially when sacrificing a black creature preserves mana for a larger sequence. Pay its alternate cost with expendable bodies, recursive `Gravecrawler`, tokens, or `Shambling Ghast` when the legal target is a must-kill creature or planeswalker; avoid sacrificing the only Zombie, only engine payoff, or only defensive blocker unless the removal prevents lethal or a decisive opposing engine. Hard-cast it when mana is available and board material is more important than tempo.

- `Chthonian Nightmare`: Treat `Chthonian Nightmare` as an attrition engine that requires real graveyard and battlefield context before commitment. Cast it when Veles shows legal exchanges involving valuable creatures, sacrifice triggers, or recursion loops; avoid casting it into public graveyard hate or when the graveyard contains no meaningful return target. It pairs especially well with `Marionette Apprentice`, `Shambling Ghast`, `Orcish Bowmasters`, and recursive `Gravecrawler` pressure, but every activation should be checked against visible legal actions rather than assumed.

- `Phoenix Fleet Airship`: Treat `Phoenix Fleet Airship` as a high-impact threat or value permanent only when Veles shows legal actions and the visible board supports tapping out. Card text check required. Do not keep or sequence a hand as if this card stabilizes by itself until rules output confirms its cast, attack, trigger, or activated ability options. Prefer deploying it after discard clears interaction or after sacrifice fodder has already established board presence.

- `Sephiroth, Fabled SOLDIER`: Treat `Sephiroth, Fabled SOLDIER` as a one-copy finisher or engine payoff that should be committed only with information, mana, and board support. Card text check required. Do not sacrifice key resources or tap out for it unless the legal action shown by Veles advances a protected endgame, stabilizes the board, or creates a short clock. Its singleton status means it should not define mulligans, but it can justify longer-game resource preservation once drawn.

- `Spymaster's Vault`: Use `Spymaster's Vault` as a singleton utility land or value engine only after confirming the legal action text. Card text check required. Do not count it as colored mana unless Veles reports it can produce the needed mana, and do not keep slow hands because it appears powerful. In grindy games, check whether deaths, attacks, or counters make its actions relevant before spending mana or sacrificing tempo.

- `Phyrexian Tower`: Use `Phyrexian Tower` as acceleration and sacrifice infrastructure, but do not treat it as a full land in hands without creatures. It is best when sacrificing `Shambling Ghast`, recursive `Gravecrawler`, tokens from `Marionette Apprentice`, or expendable Bowmasters material creates a double-spell turn. Avoid sacrificing the only creature that enables `Gravecrawler`, the only blocker against lethal pressure, or the only payoff unless the mana immediately converts into a stronger legal play.

- `Underground Mortuary`: Use `Underground Mortuary` as the slow black-green source that supports `Malevolent Rumble`, sideboard `Culling Ritual`, and other green requirements. Lead on it tapped only when no turn-one play is available or the hand can absorb the tempo loss. If the hand contains `Thoughtseize`, `Gravecrawler`, or `Shambling Ghast`, prefer untapped black sources first unless green is required for the next legal play.

- Fetchlands and shockland: Use `Marsh Flats`, `Verdant Catacombs`, `Polluted Delta`, `Bloodstained Mire`, and `Overgrown Tomb` to balance early black access with green access for `Malevolent Rumble` and post-board cards. Fetch basic `Swamp` when life total matters or green is unnecessary; fetch `Overgrown Tomb` when the hand needs green soon or sideboard cards make green urgent. Avoid unnecessary shock damage against fast creature or burn-pressure boards, especially after `Thoughtseize` or `Warren Soultrader` life payments.

- `Swamp`: Treat `Swamp` as the default stable mana source because most early plays are black and the deck spends life through fetchlands, `Thoughtseize`, and engine lines. Favor `Swamp` in openers that already have `Malevolent Rumble` delayed or no green requirement. In long games, basic-heavy sequencing reduces damage and protects against mana disruption while keeping `Flare of Malice`, `Orcish Bowmasters`, and recursive black threats reliable.

## Interaction Priorities

- Discard first when the opponent's hand contains a card that invalidates the creature engine before it starts. With `Thoughtseize`, prioritize sweepers, exile-based graveyard hate, cheap removal aimed at `Warren Soultrader`, combo pieces that win before combat matters, and planeswalkers or engines that produce repeated advantage. Take spot removal over a threat only when the hand already has `Warren Soultrader`, `Chthonian Nightmare`, or `Marionette Apprentice` and the opponent can clearly break that setup.

- Remove first the permanent that changes the next turn cycle, not the largest object by default. Use `Flare of Malice` on creatures or planeswalkers that enable combo, attack through all blockers, shut off graveyard recursion, or snowball cards; use `Orcish Bowmasters` damage on one-toughness creatures, small planeswalker loyalty, or combat math targets. Ignore medium creatures temporarily when the visible board lets `Gravecrawler`, `Shambling Ghast`, tokens, or `Marionette Apprentice` trade while the engine develops.

- Preserve `Flare of Malice` for must-answer threats when the opponent is threat-light. Do not spend it on a creature that can be blocked by `Shambling Ghast`, consumed by a sacrifice line, or raced by recursive `Gravecrawler` pressure unless life total is already under strain. Sacrifice `Gravecrawler`, tokens, or `Shambling Ghast` before `Warren Soultrader`, `Marionette Apprentice`, `Orcish Bowmasters`, or a needed Zombie.

- Bait interaction with replaceable threats before committing the engine. Lead with `Gravecrawler`, `Shambling Ghast`, `Marionette Apprentice`, or `Orcish Bowmasters` when the opponent likely has removal and the hand can follow with `Warren Soultrader` or `Chthonian Nightmare`. Commit `Warren Soultrader` into open mana only when `Thoughtseize` has cleared the way, the opponent is tapped low, or waiting gives the opponent a better clock than the engine gives you.

- Change priorities by archetype. Against combo, `Thoughtseize` takes the fastest deterministic piece or protection before removal targets; life total matters less than stopping the kill. Against creature aggro, remove haste, evasion, lord, or pump-enabling creatures first and avoid unnecessary fetch-shock plus `Thoughtseize` damage. Against control, discard sweepers, card engines, and exile answers, then force them to answer recursive threats. Against graveyard decks, post-board `Nihil Spellbomb` and `Ashiok, Dream Render` should answer graveyard function before minor board pressure. Against artifact or small-permanent decks, post-board `Culling Ritual`, `Vexing Bauble`, `Fatal Push`, `Shatter Assumptions`, and `Break the Ice` are role cards only when Veles shows legal targets or relevant timing.

- Do not invent counter, bounce, or exile lines from this main deck. If Veles offers no legal interaction action, prefer developing board, selection with `Malevolent Rumble`, or passing with a reason rather than assuming an answer exists. If sideboard actions appear, use the exact legal action text and visible targets rather than treating sideboard cards as generic answers.

## Combat And Trading Rules

- Attack when pressure does not cost the engine's next turn. Send `Gravecrawler`, expendable tokens, and surplus bodies into trades that fuel `Chthonian Nightmare`, `Marionette Apprentice`, `Warren Soultrader`, or `Phyrexian Tower`; hold back the only Zombie if `Gravecrawler` recursion depends on it. Do not attack with the only blocker against lethal or a short clock unless the attack creates lethal, forces a decisive block, or unlocks an immediate sacrifice line.

- Block to preserve life against fast decks before maximizing attrition. Trade `Shambling Ghast`, recursive `Gravecrawler`, and tokens for real attackers early, especially after fetchlands, `Thoughtseize`, or `Warren Soultrader` payments have reduced life. Chump block when the next turn's engine line is likely to stabilize; avoid chumping with `Warren Soultrader`, `Marionette Apprentice`, or `Orcish Bowmasters` unless survival or a lethal return line requires it.

- Convert dying creatures into value before damage when Veles exposes legal sacrifice actions. Use `Phyrexian Tower`, `Warren Soultrader`, or `Chthonian Nightmare` lines with creatures already marked for death, but keep the sequence legal and visible. Prefer sacrificing `Shambling Ghast`, `Gravecrawler`, or tokens; protect `Warren Soultrader` and `Marionette Apprentice` when they are the reason future turns are strong.

- Treat life thresholds as matchup-dependent. Above 12 life against fair decks, spend life more freely for `Thoughtseize`, fetchlands, and engine tempo. At 8-12 life against pressure, prioritize blockers, removal, and untapped mana over selection. At 7 or less, avoid nonessential shock damage, avoid sacrifice payments that do not affect the board, and block conservatively unless a visible lethal line exists.

- Force trades differently by role. When ahead, trade off expendable bodies and protect engines so recursion and drain-like pressure keep compounding. When behind, trade aggressively with anything except the single card that enables the recovery line. Against control or combo, attacking matters more than perfect value because each extra turn gives the opponent more draw steps; against creature decks, defensive bodies and profitable blocks matter more than chip damage.

- Use uncertain high-impact permanents only through legal runtime cues. `Phoenix Fleet Airship`, `Sephiroth, Fabled SOLDIER`, and `Spymaster's Vault` require card text checks for exact combat implications, so do not assume evasion, damage, counters, or protection unless Veles shows those actions or statuses. If they create legal attacks or blocks, evaluate them from visible board state rather than from assumed card text.

## Selection And Tutor Rules

- Selection is pseudo-selection, not a true tutor chain. `Malevolent Rumble`, `Underground Mortuary`, and fetchlands shape draws; no registered main-deck card searches for any arbitrary spell. Treat `Malevolent Rumble` as permanent selection and graveyard setup, not as access to `Thoughtseize` or `Flare of Malice`.

- Use fetchlands to solve current mana before looking for value. Fetch `Overgrown Tomb` untapped only when the turn needs green for `Malevolent Rumble`, black for `Thoughtseize`, `Orcish Bowmasters`, or `Flare of Malice`, or immediate double-spell pressure; fetch `Swamp` when life total is pressured or green is already covered. Fetch `Underground Mortuary` when a tapped land is acceptable and surveil plus black-green access matters more than tempo.

- Sequence land drops around information. Resolve `Malevolent Rumble` before the land drop when the selected permanent could decide whether to play `Phyrexian Tower`, a fetchland, or tapped `Underground Mortuary`. Play the land first only when mana is required to cast `Malevolent Rumble` or when the land decision is already forced by visible legal actions.

- Select from `Malevolent Rumble` by the missing role. Take a land when stuck below the next important turn; take `Warren Soultrader`, `Chthonian Nightmare`, or `Marionette Apprentice` when the engine is absent; take `Orcish Bowmasters` when instant-speed pressure or small-target damage matters; take `Gravecrawler` or `Shambling Ghast` when sacrifice fuel and board presence matter. Take `Spymaster's Vault`, `Phoenix Fleet Airship`, or `Sephiroth, Fabled SOLDIER` only through visible card text and board need; Card text check required for exact selection priority.

- Use `Underground Mortuary` surveil as role correction. Keep lands on top when missing land drops, keep `Thoughtseize` or `Flare of Malice` when the next turn needs interaction, and move redundant lands or redundant permanents to the graveyard only when current mana and threats are sufficient. Moving `Gravecrawler` or another creature to the graveyard is attractive only when Veles shows legal recursion, sacrifice, or `Chthonian Nightmare` access.

- Choose `Chthonian Nightmare` graveyard targets from visible legality, not memory. Return `Warren Soultrader`, `Marionette Apprentice`, or `Orcish Bowmasters` when that restores the strongest engine or interaction; return `Shambling Ghast` or `Gravecrawler` when mana, sacrifice fuel, or low-curve pressure is missing. Do not target a creature that can already be recast more efficiently unless the legal action also advances a sacrifice or lethal line.

## Priority And Stack Rules

- Treat priority passes as strategic decisions when `Orcish Bowmasters`, `Flare of Malice`, fetchlands, `Phyrexian Tower`, `Warren Soultrader`, or post-board `Nihil Spellbomb` actions are legal. Pass when the opponent's spell does not change clock, combo timing, engine survival, graveyard access, or a target you can efficiently punish.

- Cast `Orcish Bowmasters` at instant speed when the visible action will punish a draw, kill a one-toughness creature or planeswalker, change combat math, or establish a body before a sacrifice turn. Do not fire it merely because priority exists if a later draw step, cantrip, or combat window is likely and life total is stable.

- Use `Flare of Malice` only on legal creature or planeswalker targets that matter this turn cycle. Respond to pump, aura commitment, combat declarations, planeswalker pressure, or combo creature exposure when removing the target changes the outcome. Do not treat `Flare of Malice` as a counterspell; if the threat is still a spell and Veles offers no legal target, pass or use another legal action.

- Pay alternate or sacrifice costs only when the sacrificed card is replaceable or already threatened. Prefer `Gravecrawler`, tokens, or `Shambling Ghast`; avoid sacrificing `Warren Soultrader`, `Marionette Apprentice`, or the only recursion-enabling Zombie unless survival, lethal damage, or decisive removal requires it. Confirm Veles offers the exact cost action before assuming a free spell is legal.

- Convert removal and combat damage into sacrifice value at the last safe window. If a creature is targeted by exile, bounce, or lethal damage and Veles exposes `Phyrexian Tower` or `Warren Soultrader`, sacrifice it before it is lost when the mana or token matters. After blockers are declared, keep blockers in combat until blocking is locked, then use legal sacrifice actions before damage only if survival math still works.

- Interrupt graveyard actions post-board with `Nihil Spellbomb` before the opponent's reanimation, escape, delve, or recursion effect resolves if Veles shows the graveyard action and target player. Let harmless setup resolve when `Orcish Bowmasters` damage, `Flare of Malice`, or sacrifice mana would be more valuable against a visible payoff.

- Use optional triggers, activated abilities, and payments only from legal runtime text. `Chthonian Nightmare` appears sorcery-timed unless Veles shows otherwise; do not hold priority assuming instant recursion. `Marionette Apprentice`, `Shambling Ghast`, `Spymaster's Vault`, `Phoenix Fleet Airship`, and `Sephiroth, Fabled SOLDIER` require visible trigger or ability choices before selecting targets or modes; Card text check required for any non-obvious option.

## Sideboard Map

- Sideboard from role first, then card text. `Fatal Push` is the clean creature-density upgrade, `Nihil Spellbomb` is the graveyard-control upgrade, `Vexing Bauble` is the anti-free-spell or anti-alternate-cost upgrade, `Ashiok, Dream Render` is the search-and-graveyard pressure upgrade, `Culling Ritual` is the low-mana-permanent reset, `Break the Ice` is the greedy-mana or snow-land pressure card, and `Shatter Assumptions` requires card text check before assigning exact targets or timing.

- Add `Fatal Push` when cheap creatures decide the first four turns. Bring it against creature-combo, small aggro, mana-creature starts, and battlefield snowball decks where `Flare of Malice` is too costly or too narrow. It is weaker when the opponent presents mostly spells, large noncreature threats, or permanents that must be answered before a creature exists.

- Add `Nihil Spellbomb` when the opponent's graveyard is a visible resource. Prioritize it against recursion, reanimation, delve, escape, graveyard delirium, and decks that make combat or combo decisions from graveyard quantity. It is lower impact when the opponent only incidentally fills the graveyard and you need board pressure, discard, or removal more than a held artifact.

- Add `Vexing Bauble` when the opponent's most dangerous turns involve paying no mana or using alternate/free-cast patterns. Use it as a commitment check: if Veles shows legal deployment before the opponent can exploit a free spell line, cast it early; if it conflicts with your own immediate engine turn, evaluate whether stopping their burst matters more than developing `Warren Soultrader`, `Marionette Apprentice`, or `Malevolent Rumble`. It is weak against fair creature decks that spend mana normally and do not rely on cascade-style, free-spell, or zero-mana pressure. Card text check required for exact activated or triggered choices.

- Add `Ashiok, Dream Render` against search-heavy, graveyard-reliant, or land-search decks. It is strongest when the opponent's fetchlands, tutors, or graveyard plan matter more than your creature removal. It is weaker when the opponent attacks planeswalkers easily, ignores searching, or pressures life total so fast that a noncreature, non-removal turn loses tempo.

- Add `Culling Ritual` when the opponent has many cheap nonland permanents. It should be treated as a comeback or tempo-swing card, not as routine removal, because your own `Gravecrawler`, `Shambling Ghast`, `Marionette Apprentice`, `Warren Soultrader`, `Chthonian Nightmare`, `Spymaster's Vault`, and `Nihil Spellbomb` can be exposed if Veles shows them as affected permanents. It is bad when your battlefield is the stronger cheap-permanent board and the opponent's relevant threats cost too much or are mostly spells.

- Add `Break the Ice` against greedy mana, snow lands, or land types that Veles confirms are legal targets. Use it to attack colors or tempo when the opponent's deck depends on a small number of lands producing key colors. It is weak against basic-heavy decks, low-curve decks that already deployed threats, or positions where spending a turn on land interaction fails to affect combat or combo timing. Card text check required for exact target restrictions.

- Add `Shatter Assumptions` only when Veles card text or matchup context confirms the opponent has the card class it punishes. Treat it as conditional disruption, not generic discard. It is weak when the opponent's hand composition is unknown and `Thoughtseize`, `Orcish Bowmasters`, or board development would apply broader pressure. Card text check required before assuming which colors, mana values, or card types it can affect.

Creature-heavy low-curve aggro
Side in: 3 Fatal Push; 3 Culling Ritual
Cut: 2 Thoughtseize; 1 Spymaster's Vault; 3 Phoenix Fleet Airship

- Plan rule: Keep `Orcish Bowmasters`, `Shambling Ghast`, `Marionette Apprentice`, and sacrifice outlets because they create bodies, trades, and removal insulation. Reduce slower singletons and expensive or uncertain threats first, then reduce discard when life loss and tempo are more dangerous than hidden-card disruption. Avoid `Culling Ritual` if your own cheap board is already winning unless the legal action clearly breaks parity.

Graveyard recursion or reanimation
Side in: 2 Nihil Spellbomb; 1 Ashiok, Dream Render
Cut: 1 Spymaster's Vault; 1 Flare of Malice; 1 Phoenix Fleet Airship

- Plan rule: Keep pressure plus discard, then add graveyard containment. `Nihil Spellbomb` should be deployed early when the opponent can use the graveyard at instant or sorcery speed, but it should be activated only when a visible payoff, threshold, or target makes the graveyard matter. `Ashiok, Dream Render` is better on boards where it survives at least a turn cycle or immediately blocks search or graveyard lines.

Free-spell, cascade, or alternate-cost combo
Side in: 3 Vexing Bauble; 1 Shatter Assumptions; 1 Ashiok, Dream Render
Cut: 3 Flare of Malice; 1 Spymaster's Vault; 1 Phoenix Fleet Airship

- Plan rule: Preserve `Thoughtseize` and fast pressure while adding rule-text disruption. `Flare of Malice` becomes less important when the decisive object is not a creature or planeswalker on the battlefield, but keep it instead if Veles shows the opponent depends on a removable creature. `Vexing Bauble` should enter before the opponent's explosive turn when legal, even if that delays a slower value permanent.

Greedy mana or snow-heavy control
Side in: 2 Break the Ice; 1 Ashiok, Dream Render; 1 Shatter Assumptions
Cut: 2 Shambling Ghast; 1 Flare of Malice; 1 Phoenix Fleet Airship

- Plan rule: Attack mana and search while maintaining a clock. `Break the Ice` is valuable only if Veles shows legal targets that restrict key colors or tempo; do not spend it on a low-impact land when developing `Warren Soultrader`, `Marionette Apprentice`, or `Malevolent Rumble` advances pressure more. `Thoughtseize` stays important because it identifies sweepers, finishers, and interaction windows.

Artifact-token or cheap-permanent battlefield decks
Side in: 3 Culling Ritual; 3 Fatal Push; 2 Nihil Spellbomb
Cut: 4 Thoughtseize; 1 Spymaster's Vault; 1 Flare of Malice; 2 Phoenix Fleet Airship

- Plan rule: Become a board-control deck and let sacrifice value rebuild after exchanges. `Culling Ritual` is highest impact when it removes multiple opposing permanents while your follow-up uses the mana or leaves recursive pressure. `Nihil Spellbomb` is included only when the opponent also uses graveyard artifacts, recursion, or death triggers; otherwise prefer `Vexing Bauble` or leave the main deck intact depending on visible matchup notes.

Broad archetype rule: against fast aggro, Add role cards: `Fatal Push`; `Culling Ritual`. Reduce main-deck emphasis: slow singletons, uncertain top-end, and discard that costs life when the opponent is already emptying hand.

Broad archetype rule: against spell-combo, Add role cards: `Vexing Bauble`; `Shatter Assumptions`; `Ashiok, Dream Render` when search or graveyard matters. Reduce main-deck emphasis: creature removal that has no visible targets and slow permanents that do not shorten the clock.

Broad archetype rule: against graveyard decks, Add role cards: `Nihil Spellbomb`; `Ashiok, Dream Render`. Reduce main-deck emphasis: slow nonessential threats before reducing `Thoughtseize`, because discard plus graveyard containment can prevent the payoff from ever becoming legal.

Broad archetype rule: against control, Add role cards: `Break the Ice` when mana targets are legal, `Ashiok, Dream Render` when search matters, and `Vexing Bauble` only when free interaction or alternate-cost spells are confirmed. Reduce main-deck emphasis: low-impact removal and creatures that fail to pressure through visible blockers or sweepers.

Broad archetype rule: against unknown opponents after Game 1, sideboard only from observed evidence. Do not assume `Vexing Bauble`, `Break the Ice`, `Nihil Spellbomb`, or `Shatter Assumptions` is correct without public information, matchup label, or card text showing the relevant axis.

## Matchup Guidance

- Aggro: Stabilize before maximizing engine value. Keep hands that produce early black mana, at least one cheap body, and either `Orcish Bowmasters`, `Shambling Ghast`, `Marionette Apprentice`, `Flare of Malice`, or `Fatal Push` after sideboarding. Treat `Thoughtseize` as strongest when it prevents the first high-impact threat or combat trick, but reduce main-deck emphasis on life-loss discard when the opponent empties quickly and visible board pressure is already the problem. Add role cards: `Fatal Push`; `Culling Ritual`. Reduce main-deck emphasis: slow singletons, expensive pressure, and `Spymaster's Vault` when the board is not safe enough to invest in it.

- Burn: Protect life total as a primary resource, not a buffer for extra information. Favor `Orcish Bowmasters` and recursive bodies when they trade without costing life, but avoid fetch-shock sequencing unless a legal play requires the color or timing. Use `Thoughtseize` only when the visible hand or matchup label implies a card that is more damaging than the two life paid, such as a decisive payoff or scarce answer to your board. Add role cards: `Fatal Push` for creature-heavy versions and `Vexing Bauble` only if public information confirms free or alternate-cost spells. Reduce main-deck emphasis: self-damaging disruption and slow value permanents.

- Control: Lead with discard and diversified pressure rather than overcommitting every permanent into a sweeper. `Thoughtseize` should prioritize sweepers, card-advantage engines, and clean answers to `Warren Soultrader`, `Chthonian Nightmare`, or recursive `Gravecrawler` pressure. Deploy `Orcish Bowmasters` when it punishes visible draw actions or pressures planeswalkers, but do not assume the opponent will draw extra cards unless Veles shows the spell or trigger. Add role cards: `Break the Ice` when legal land targets matter, `Ashiok, Dream Render` when search or graveyard lines matter, `Shatter Assumptions` only after card text or matchup evidence confirms relevance, and `Vexing Bauble` only against free interaction or alternate-cost turns. Reduce main-deck emphasis: creature removal with no visible targets and low-impact bodies that cannot pressure through public blockers.

- Combo: Race with disruption first, then execute the sacrifice-recursion engine once the opponent is constrained. `Thoughtseize` should take the card that enables the earliest win, protects the combo, or defeats your hate piece; do not spend it on a redundant cantrip-equivalent when a payoff or enabler is visible. `Vexing Bauble` is a priority role card against free-spell, cascade, or alternate-cost combo, while `Ashiok, Dream Render` matters against search and graveyard setup. Add role cards: `Vexing Bauble`; `Ashiok, Dream Render`; `Nihil Spellbomb`; `Shatter Assumptions` when its text applies. Reduce main-deck emphasis: `Flare of Malice` when the combo is not creature-based, and slow threats that do not shorten the clock.

- Tempo: Trade efficiently, preserve mana discipline, and make the opponent spend cards answering recursive threats. Keep one-mana plays and fetch sequencing flexible so `Fatal Push`, `Thoughtseize`, `Gravecrawler`, and `Shambling Ghast` can be used on time. `Orcish Bowmasters` is valuable when it punishes draw spells or creates a flash-speed body that contests attacks, but avoid waiting for an uncertain trigger if using mana now prevents damage or advances a confirmed engine. Add role cards: `Fatal Push`; `Vexing Bauble` when free spells are visible; `Break the Ice` only when land disruption attacks their tempo base. Reduce main-deck emphasis: slow top-end and speculative value lines that lose to open mana.

- Midrange: Become the recursive resource deck and force exchanges that leave `Gravecrawler`, tokens, `Chthonian Nightmare`, or death triggers still relevant. Use `Thoughtseize` to clear exile removal, sweepers, planeswalkers, and threats that dominate creature combat. `Flare of Malice` should answer the threat that invalidates your board or wins the race, not the first legal target by default. `Malevolent Rumble` is valuable when it finds material for the engine or smooths land development, but Card text check required for exact selection and graveyard implications. Add role cards: `Fatal Push` for creature density, `Nihil Spellbomb` against recursion, and `Culling Ritual` only when the opponent presents multiple cheap permanents. Reduce main-deck emphasis: cards whose text is weak into the visible battlefield.

- Big mana: Pressure early, attack setup, and avoid hands that only answer creatures after the opponent goes over the top. `Thoughtseize` should take the payoff, sweeper, search spell, or stabilizer that breaks the current clock. Add role cards: `Break the Ice` when Veles confirms legal, meaningful land targets; `Ashiok, Dream Render` when search is part of the opponent's plan; `Vexing Bauble` only when alternate-cost or free-spell turns are confirmed. Reduce main-deck emphasis: removal that has no target and sacrifice value that is too slow without pressure.

- Graveyard: Separate graveyard containment from board stabilization. `Nihil Spellbomb` should be deployed before the graveyard becomes lethal when possible, but activation should wait for a visible payoff, target, threshold, or forced timing unless leaving it unused risks losing it. `Ashiok, Dream Render` is strongest when it blocks search while also limiting graveyard use. Keep `Thoughtseize` to remove enablers or answers to hate. Add role cards: `Nihil Spellbomb`; `Ashiok, Dream Render`; `Fatal Push` when creature engines matter. Reduce main-deck emphasis: slow single-card threats before weakening discard plus pressure.

- Artifact/enchantment: Identify whether the opponent is a cheap-permanent battlefield deck, a single lock-piece deck, or a combo deck using artifacts or enchantments. `Culling Ritual` is a swing card when it removes multiple opposing cheap nonland permanents and your follow-up uses the mana or rebuilds through recursive bodies; it is dangerous when it destroys your stronger board. `Vexing Bauble` is for spell-cost rules, not generic artifacts. Add role cards: `Culling Ritual`; `Fatal Push` when creature artifacts matter; `Vexing Bauble` only for confirmed free or alternate-cost plans. Reduce main-deck emphasis: discard only when the battlefield is already the decisive zone.

- Go-wide: Treat bodies, death triggers, and sweep-like effects as the route to parity. `Orcish Bowmasters`, `Shambling Ghast`, `Marionette Apprentice`, and `Gravecrawler` help create trades while keeping material flowing. `Culling Ritual` should be considered when the opponent's board has many cheap permanents and your own affected permanents are either expendable or recoverable. `Flare of Malice` should remove a lord, payoff, or evasive threat rather than a replaceable token when Veles shows that choice. Add role cards: `Fatal Push`; `Culling Ritual`. Reduce main-deck emphasis: slow value permanents and single threats without immediate board impact.

- Single-threat: Save premium interaction for the threat that matters and avoid using removal just because it is legal. `Thoughtseize` should take protection, recursion, or the threat itself when visible. `Flare of Malice` and `Fatal Push` should be held for the high-impact creature unless life total, mana efficiency, or a forced window demands action. Sacrifice fodder from `Shambling Ghast`, `Marionette Apprentice`, `Gravecrawler`, and `Phoenix Fleet Airship` may support `Flare of Malice`; Card text check required for exact token and sacrifice interactions. Add role cards: `Fatal Push`; `Nihil Spellbomb` if the threat recurs from graveyard. Reduce main-deck emphasis: broad board-swing cards when the opponent commits only one relevant permanent.

- Removal-heavy: Make every exchange punish the opponent by leaning on recursive and death-triggered material. Prioritize `Gravecrawler` access, sacrifice outlets, and `Chthonian Nightmare` when they are legal and protected by visible resources. Do not expose `Warren Soultrader` or `Spymaster's Vault` into open removal if the same mana can create multiple must-answer objects, unless the current clock or hand demands commitment. Add role cards: `Nihil Spellbomb` for opposing recursion and `Ashiok, Dream Render` for graveyard/search engines, while `Fatal Push` is only necessary if their threats still require cheap answers. Reduce main-deck emphasis: one-for-one removal when the opponent has few creatures.

- Unknown Game 1: Use public information before assigning an archetype. Early fetch lands, revealed cards, graveyard contents, companion status if any, and first threats should decide whether to protect life, accelerate pressure, or conserve interaction. Keep broadly functional hands with black mana, an early play, and either disruption or engine material. Do not assume sideboard cards such as `Vexing Bauble`, `Break the Ice`, `Nihil Spellbomb`, `Ashiok, Dream Render`, `Shatter Assumptions`, `Culling Ritual`, or `Fatal Push` are correct until the matchup label, observed cards, or visible board state identifies their axis.

## Specific Matchup Notes
- General/archetype-only note: Revealed cards override assumptions, so treat these notes as starting heuristics until Veles shows public cards, zones, actions, or matchup labels. Keep `Thoughtseize` targets tied to the opponent's visible plan, keep `Fatal Push` for creature matchups, keep `Nihil Spellbomb` and `Ashiok, Dream Render` for graveyard/search pressure, keep `Culling Ritual` for cheap-permanent boards, keep `Break the Ice` for land bases it can legally punish, and keep `Vexing Bauble` for visible free-spell or alternate-cost pressure.

- Fast creature pressure: Prioritize life total and board presence before slow engine expansion. `Shambling Ghast`, `Marionette Apprentice`, `Gravecrawler`, `Orcish Bowmasters`, and tokens can trade early while preserving sacrifice material for `Flare of Malice` or `Warren Soultrader`. Likely sideboard emphasis is `Fatal Push` and sometimes `Culling Ritual`; priority targets are lords, haste/evasion threats, and creatures that make blocking impossible.

- Blue tempo or spell-heavy decks: Force them to spend mana on your recursive threats while `Thoughtseize` clears the counter, bounce, or removal spell that stops the current line. `Orcish Bowmasters` is a flash-speed pressure card when the opponent draws extra cards, but do not hold all development waiting for an uncertain trigger. Likely sideboard emphasis is `Vexing Bauble` only when cost-cheating is visible, plus `Fatal Push` if creatures define the clock; priority targets are engines, protected threats, and interaction that answers `Chthonian Nightmare` or `Warren Soultrader`.

- Graveyard decks: Deploy hate early enough that activation timing remains yours. `Nihil Spellbomb` should threaten the graveyard before a payoff resolves, while `Ashiok, Dream Render` matters most when search or graveyard access is part of the opponent's public plan. Keep pressure with `Gravecrawler`, `Marionette Apprentice`, and `Phoenix Fleet Airship`; Card text check required for exact `Phoenix Fleet Airship` tactical roles. Priority targets are enablers, recursion payoffs, and answers to hate.

- Big mana and land-engine decks: Mulligan toward disruption plus pressure, not removal-only hands. `Thoughtseize` should take payoff spells, sweepers, search pieces, or stabilizers according to the visible hand and clock. Likely sideboard emphasis is `Break the Ice` when legal targets are meaningful and `Ashiok, Dream Render` when search is confirmed; priority targets are ramp/search effects, sweepers, and cards that invalidate small recursive pressure.

- Cheap artifact/enchantment boards: Use `Culling Ritual` only when the visible exchange is favorable or your own affected board is expendable and recoverable. `Marionette Apprentice`, `Shambling Ghast`, and `Gravecrawler` can make symmetric clearing less painful, but sacrificing a developed engine into no follow-up is a risk. Likely sideboard emphasis is `Culling Ritual`; priority targets are payoff permanents, mana engines, and permanents that block recursion or sacrifice value.

- Removal-heavy midrange/control: Preserve recursive density and avoid making a single permanent carry the whole game. `Chthonian Nightmare`, `Gravecrawler`, death-trigger creatures, and sacrifice fodder should make one-for-one removal awkward. `Sephiroth, Fabled SOLDIER` and `Spymaster's Vault` require Card text check required before assuming finisher or engine roles. Priority targets are exile effects, sweepers, planeswalkers, and graveyard hate.

## Risk Summary
- Mana risk: The deck is heavily black and uses `Phyrexian Tower`, fetch lands, `Overgrown Tomb`, `Underground Mortuary`, and `Swamp`, so opening hands without functional black mana or without a castable early spell should be treated skeptically. Fetch-shock sequencing can cost races; preserve life against fast starts unless the untapped source enables `Thoughtseize`, `Gravecrawler`, `Shambling Ghast`, `Orcish Bowmasters`, or `Fatal Push` at a decisive time.

- Matchup risk: The deck can mis-role itself by becoming too slow against big mana or too reckless against removal-heavy decks. Use public information to decide whether the first job is discard plus clock, stabilize with bodies and removal, or assemble recursive attrition.

- Draw risk: Hands with only sacrifice payoffs and no fodder, or fodder with no pressure/disruption, can produce legal actions that do not advance the game. `Malevolent Rumble`, `Chthonian Nightmare`, `Warren Soultrader`, `Spymaster's Vault`, `Sephiroth, Fabled SOLDIER`, and `Phoenix Fleet Airship` need Card text check required for exact tactical assumptions when they appear in unclear lines.

- Over-sideboarding risk: Adding narrow cards can dilute the recursive creature engine and leave `Flare of Malice`, `Warren Soultrader`, or sacrifice lines under-supported. Do not emphasize `Vexing Bauble`, `Break the Ice`, `Nihil Spellbomb`, `Ashiok, Dream Render`, `Shatter Assumptions`, or `Culling Ritual` unless the opponent's revealed cards justify that axis.

- Graveyard risk: Your own `Gravecrawler` and `Chthonian Nightmare` plans may be weakened by opposing hate, exile removal, or your own graveyard timing. Do not rely on recursion as certainty when the opponent has visible graveyard interaction or open mana representing it.

- Sweeper/removal risk: Overcommitting `Marionette Apprentice`, `Warren Soultrader`, `Gravecrawler`, `Shambling Ghast`, and token material can lose tempo to sweepers, but undercommitting can fail to pressure combo or big mana. Sequence threats so a sweeper leaves either graveyard recursion, hand follow-up, or a post-sweeper engine.

- Closer risk: The deck may stabilize without ending the game quickly. When ahead, convert recursive material into damage, preserve a meaningful clock, and use `Thoughtseize` or `Flare of Malice` to stop the card that resets the board.

- Interaction risk: `Thoughtseize`, `Fatal Push`, and `Flare of Malice` are easy to spend on the first legal target. Hold premium interaction for threats, payoffs, or answers that change the current race unless life total or forced timing makes immediate use necessary.

- Sequencing risk: Sacrifice, recursion, and mana-source choices can lock out later legal actions. Before using `Phyrexian Tower`, `Warren Soultrader`, `Flare of Malice`, or `Chthonian Nightmare`, check whether the sacrificed permanent, mana color, or graveyard object is required for the next visible action.

- Deciding factor: Record whether the game was decided by early discard plus pressure, recursive sacrifice value, a specific sideboard card, opponent speed, mana failure, or a stalled closing plan. Note the exact turn where the winning side became favored from visible board state.

- Mulligans: Ask whether the opener had black mana, an early legal spell, and either pressure or disruption. Flag keeps that had `Phyrexian Tower` without enough creature material, sacrifice engines without fodder, or only slow cards such as `Spymaster's Vault`, `Sephiroth, Fabled SOLDIER`, or `Phoenix Fleet Airship`; Card text check required for exact slow-card labels.

- Mana: Track whether `Marsh Flats`, `Verdant Catacombs`, `Polluted Delta`, `Bloodstained Mire`, `Overgrown Tomb`, `Underground Mortuary`, `Swamp`, and `Phyrexian Tower` produced the colors and timing needed. Record games where shock/fetch life loss made `Thoughtseize` or racing worse.

- Velocity: Ask whether `Malevolent Rumble` found relevant material or consumed tempo while behind. Record whether the deck had enough one- and two-mana actions to pressure combo, stabilize against creatures, and rebuild after removal.

- Engines: Record when `Chthonian Nightmare`, `Warren Soultrader`, `Marionette Apprentice`, `Gravecrawler`, `Shambling Ghast`, and `Phyrexian Tower` produced repeatable advantage versus when pieces were stranded separately. Identify whether sacrifice choices preserved the permanent or graveyard card needed for the next legal action.

- Removal and disruption: Ask whether `Thoughtseize`, `Flare of Malice`, and sideboard `Fatal Push` hit cards that actually changed the game. Flag early interaction spent on low-impact targets while a visible payoff, clock, sweeper, or hate card remained unhandled.

- Sideboard: Check whether `Vexing Bauble`, `Nihil Spellbomb`, `Ashiok, Dream Render`, `Shatter Assumptions`, `Culling Ritual`, `Break the Ice`, and `Fatal Push` matched revealed opponent plans. Mark any game where narrow cards sat unused or diluted the recursive creature count.

- Closing: Ask whether the deck converted stabilization into lethal pressure with `Orcish Bowmasters`, `Marionette Apprentice`, `Gravecrawler`, tokens, or other visible threats. Record turns where the pilot passed, over-defended, or spent mana on low-impact actions instead of shortening the clock.

- Role discipline: Record whether the pilot correctly played as aggressor, stabilizer, or attrition deck after public information changed. Flag games where `Thoughtseize` took a defensive card while racing was required, or removal was held while survival was the priority.

- Mistakes and stranded cards: List every stranded `Flare of Malice`, `Chthonian Nightmare`, `Warren Soultrader`, `Spymaster's Vault`, `Sephiroth, Fabled SOLDIER`, `Phoenix Fleet Airship`, or sideboard card and identify the missing resource, timing window, or legal target.

- Overperformers and underperformers: Count which exact cards generated wins, stabilized losses, or failed to affect the board. Separate card strength from pilot sequencing and from Card text check required uncertainty.

## First Tuning Questions
- Card quantities: Does `Chthonian Nightmare` need more copies if recursion wins long games, or fewer if it is often stranded without the right graveyard and board? Does `Flare of Malice` need adjustment if free interaction is decisive but sacrifice costs repeatedly break the engine?

- Creature package: Are four each of `Marionette Apprentice`, `Warren Soultrader`, `Gravecrawler`, `Shambling Ghast`, and `Orcish Bowmasters` producing the right mix of fodder, pressure, and interaction? If the deck floods on setup creatures without payoffs, identify which body was weakest in the logged matchup.

- Mana base: Are four `Phyrexian Tower` enabling explosive sacrifice lines often enough to justify legendary or color-timing risk? Are two `Underground Mortuary`, one `Overgrown Tomb`, and the fetch mix supporting black-heavy starts without too many tapped or painful openings?

- Velocity and selection: Is `Malevolent Rumble` improving consistency, or is it too slow when the opponent attacks quickly? If it overperforms, ask whether the deck wants more graveyard-aware engine density rather than more reactive cards.

- Closers: Does the deck lose after stabilizing because `Gravecrawler`, tokens, and chip damage are too slow? Card text check required before changing assumptions around `Spymaster's Vault`, `Sephiroth, Fabled SOLDIER`, and `Phoenix Fleet Airship` as finishers or value engines.

- Aggro plan: Are post-board `Fatal Push` and `Culling Ritual` enough against fast creature pressure, or does the main deck need more early interaction? Identify whether losses came from missing removal, tapped mana, life loss from `Thoughtseize`, or weak blocks.

- Control and combo plan: Is four `Thoughtseize` plus pressure enough to beat slow or spell-heavy opponents, or do sideboard cards need to shift toward more disruption? Track whether `Vexing Bauble`, `Shatter Assumptions`, `Ashiok, Dream Render`, and `Break the Ice` were relevant when drawn.

- Graveyard plan: Does `Nihil Spellbomb` plus `Ashiok, Dream Render` cover graveyard opponents without weakening `Gravecrawler` and `Chthonian Nightmare` too much? Check whether hate was deployed early enough or held for a more decisive activation.

- Sideboard slots: Is `Culling Ritual` winning enough artifact, enchantment, or small-permanent board states to justify three slots? Are three `Vexing Bauble` too many if opponents are not visibly relying on free or alternate-cost spells?

- Role conflicts: Does the list ask the pilot to be aggressive, attrition-based, and engine-focused at the same time without enough card flow? Tune only after logs show whether losses are from wrong role choice, insufficient legal action density, or individual card underperformance.

## Veles Tactical Policy

### Policy: Keep Functional Black Starts
Priority: High
Decision families: mulligan, pregame
Cards: Thoughtseize; Gravecrawler; Shambling Ghast; Marionette Apprentice; Orcish Bowmasters; Malevolent Rumble; Phyrexian Tower
Phase windows: opening hand, mulligan decisions
Runtime cues: opening hand; mulligan action
Use when: Evaluate every opener for black mana, a legal turn-one or turn-two play, and either disruption, pressure, or sacrifice material.
Avoid when: Do not keep hands that only contain slow or uncertain cards such as Spymaster's Vault, Sephiroth, Fabled SOLDIER, or Phoenix Fleet Airship without early black action; Card text check required for exact slow-card use.
Instructions: Prefer hands with Thoughtseize plus creature pressure, or creature plus engine mana. Treat Phyrexian Tower as strong only when at least one expendable creature or recursive creature is present.

### Policy: Early Creature Foundation
Priority: Medium
Decision families: mana, priority
Cards: Gravecrawler; Shambling Ghast; Marionette Apprentice; Orcish Bowmasters; Warren Soultrader
Phase windows: turns 1-3, main phases
Runtime cues: legal cast actions for one- and two-mana creatures
Use when: Select the first board commitment after mana is available and no urgent interaction must be held.
Avoid when: Opponent has a visible must-answer threat, or the only creature would be needed to pay a visible cost this turn.
Instructions: Establish sacrifice fodder before spending Phyrexian Tower or Warren Soultrader lines. Prefer recursive or expendable creatures when planning Chthonian Nightmare or Flare of Malice costs.

### Policy: Phyrexian Tower Commitment Gate
Priority: High
Decision families: mana, priority
Cards: Phyrexian Tower; Gravecrawler; Shambling Ghast; Marionette Apprentice; Warren Soultrader; Chthonian Nightmare
Phase windows: main phases, priority windows with mana abilities
Runtime cues: legal mana actions involving Phyrexian Tower
Use when: Decide whether sacrificing a creature for mana advances a visible spell, recursion line, or lethal/survival line this turn.
Avoid when: The sacrificed creature is the only visible creature needed for Gravecrawler access, Chthonian Nightmare setup, blocking, or Flare of Malice.
Instructions: Treat Phyrexian Tower as a tempo burst, not free mana. Spend creatures that are recursive, replace themselves, or are already outclassed before sacrificing key engines.
Pilot skill floor: light-model
No-API allowed: no
Light-model allowed: yes

### Policy: Fetch And Shock Discipline
Priority: Medium
Decision families: mana
Cards: Marsh Flats; Verdant Catacombs; Polluted Delta; Bloodstained Mire; Overgrown Tomb; Underground Mortuary; Swamp
Phase windows: land play, fetch activation, early turns
Runtime cues: action:play Marsh Flats; action:play Verdant Catacombs; action:activate Marsh Flats; action:activate Verdant Catacombs
Use when: A legal land or fetch action is available and the current hand needs black mana now or green mana for Malevolent Rumble.
Avoid when: Life total is under visible pressure and untapped Overgrown Tomb is not required for a same-turn legal action.
Instructions: Prioritize untapped black for Thoughtseize, one-drops, and interaction. Fetch basic Swamp when green is not needed and life preservation matters; fetch Overgrown Tomb when Malevolent Rumble or sideboard green spells require it.

No-API allowed: no
Light-model allowed: yes

### Policy: Thoughtseize Disruption Gate
Priority: High
Decision families: interaction, priority, selection
Cards: Thoughtseize
Phase windows: precombat main phase, early turns, before committing engines
Runtime cues: legal Thoughtseize cast and revealed-hand choice prompts
Use when: Cast or resolve Thoughtseize to remove the opponent card most likely to beat the visible plan.
Avoid when: Life loss creates a visible lethal or near-lethal race and the opponent hand is not known to contain a decisive card.
Instructions: Take fast combo pieces, sweepers, graveyard hate, removal for the only engine, or the card that prevents the current pressure from closing. Use revealed information; never infer exact hidden cards beyond the displayed hand.

### Policy: Discard Target Resolution
Priority: Medium
Decision families: selection, interaction
Cards: Thoughtseize
Phase windows: Thoughtseize resolution
Runtime cues: action:choose card from opponent hand
Use when: The rules engine presents revealed opponent hand cards as legal Thoughtseize choices.
Avoid when: The target choice requires matchup-role reasoning not visible in the action labels alone.
Instructions: Choose the visible card that stops the selected line: combo payoff when racing combo, sweeper against pressure, removal against a fragile engine, or fastest threat when stabilizing.
Pilot skill floor: light-model
No-API allowed: no
Light-model allowed: yes

### Policy: Sacrifice Engine Commitment
Priority: High
Decision families: priority, mana, selection
Cards: Warren Soultrader; Chthonian Nightmare; Marionette Apprentice; Gravecrawler; Shambling Ghast
Phase windows: main phases, sacrifice prompts, recursion prompts
Runtime cues: legal actions involving Warren Soultrader or Chthonian Nightmare
Use when: Decide whether to start converting creatures into mana, recursion, drains, counters, or board material.
Avoid when: The line consumes the last creature, loses the only blocker under pressure, or exposes the engine to visible interaction without immediate gain.
Instructions: Start the engine when it produces board, mana, cards, or damage this turn, or when waiting loses to visible pressure. Preserve Gravecrawler access and leave enough material for future sacrifice prompts.
Pilot skill floor: light-model
No-API allowed: no
Light-model allowed: yes

### Policy: Recursive Creature Targeting
Priority: Medium
Decision families: selection, priority
Cards: Chthonian Nightmare; Gravecrawler
Phase windows: main phases, recursion prompts
Runtime cues: action:target self Gravecrawler; action:cast Gravecrawler from graveyard
Use when: A legal action text explicitly offers Gravecrawler from the graveyard and the required creature condition is already satisfied by visible state.
Avoid when: Paying the cost removes the only visible creature enabling the action or prevents a required block this turn.
Instructions: Execute Gravecrawler recursion after the engine commitment is selected. Use light-model if multiple graveyard or return targets exist.
Pilot skill floor: rules-aware
No-API allowed: yes
Light-model allowed: yes

### Policy: Flare Of Malice Cost Gate
Priority: High
Decision families: interaction, priority, selection
Cards: Flare of Malice; Gravecrawler; Shambling Ghast; Marionette Apprentice; Orcish Bowmasters
Phase windows: opponent turn, combat, stack interaction, removal windows
Runtime cues: legal Flare of Malice cast or alternate-cost prompt
Use when: Decide whether free or low-mana interaction is worth sacrificing a creature to answer a visible threat, protect the race, or survive.
Avoid when: The target is low-impact, the sacrificed creature is the only engine enabler, or waiting preserves a higher-impact answer with no immediate danger.
Instructions: Prefer expendable or recursive sacrifice material. Spend Flare of Malice on threats or engines that materially change the game, not on creatures already contained by blocks or racing.
Pilot skill floor: light-model
No-API allowed: no
Light-model allowed: yes

### Policy: Bowmasters Timing
Priority: Medium
Decision families: interaction, priority, combat
Cards: Orcish Bowmasters
Phase windows: opponent draw effects, combat tricks, end step, main phase with flash action
Runtime cues: legal cast Orcish Bowmasters
Use when: Decide whether to hold or cast Orcish Bowmasters around visible draw effects, x/1 creatures, combat math, or pressure needs.
Avoid when: Casting into open mana gives up a stronger visible trigger window and board pressure is not urgent.
Instructions: Use Orcish Bowmasters as interaction when the opponent is drawing extra cards or presenting one-toughness creatures; use it as pressure when discard has cleared answers or racing matters.
Pilot skill floor: light-model
No-API allowed: no
Light-model allowed: yes

### Policy: Malevolent Rumble Selection
Priority: Medium
Decision families: selection, priority
Cards: Malevolent Rumble; Chthonian Nightmare; Warren Soultrader; Phyrexian Tower; Gravecrawler
Phase windows: main phase, selection resolution
Runtime cues: legal Malevolent Rumble cast or selection prompt
Use when: Cast or resolve Malevolent Rumble to find missing engine, mana, or threat material while respecting current tempo.
Avoid when: The opponent has visible lethal pressure and a legal removal, blocker, or discard line is available instead.
Instructions: Prioritize the card type or object that completes the next visible line: mana when stuck, creature when Tower or sacrifice engine needs fodder, engine when fodder is already present.
Pilot skill floor: light-model
No-API allowed: no
Light-model allowed: yes

### Policy: Marionette Apprentice Pressure Math
Priority: Medium
Decision families: combat, priority
Cards: Marionette Apprentice; Warren Soultrader; Gravecrawler; Shambling Ghast; Phyrexian Tower
Phase windows: combat, sacrifice prompts, main phases before attacks
Runtime cues: legal sacrifice actions; combat damage projections
Use when: Visible sacrifice triggers or creature deaths can change life totals, blocks, or lethal clocks.
Avoid when: Card text uncertainty affects exact damage, token, or trigger output; Card text check required.
Instructions: Count visible drain or damage triggers before choosing attacks or sacrifices. Choose lines that convert expendable bodies into lethal pressure or stabilize while preserving the recursive loop.

### Policy: Combat Role Selection
Priority: Medium
Decision families: combat
Cards: Gravecrawler; Shambling Ghast; Marionette Apprentice; Orcish Bowmasters; Warren Soultrader; Sephiroth, Fabled SOLDIER; Phoenix Fleet Airship
Phase windows: declare attackers, declare blockers, combat tricks
Runtime cues: legal attack or block actions with current creatures
Use when: Choose attacks and blocks from visible board state after identifying whether the deck is racing, stabilizing, or preserving engines.
Avoid when: A single broad attack or block cue lacks damage, blocker, or trigger context.
Instructions: Attack when recursive bodies and tokens pressure life without exposing essential engines. Block when life total or planeswalker pressure matters more than preserving expendable creatures. Card text check required for Sephiroth, Fabled SOLDIER and Phoenix Fleet Airship combat roles.
Pilot skill floor: light-model
No-API allowed: no

### Policy: Exact Single Forced Block Or No-Block
Priority: Low
Decision families: combat
Cards: none
Phase windows: declare blockers
Runtime cues: action:block with exactly one legal blocker assignment; action:no blocks
Use when: The rules engine offers exactly one block action or exactly one no-block action and no other combat action is legal.
Avoid when: Multiple blockers, multiple attackers, sacrifice outlets, removal, or prevention actions are legal.
Instructions: Submit the only legal combat continuation when Veles has already determined no strategic choice remains.

### Policy: Sideboard Plan Selection
Priority: High
Decision families: sideboard
Cards: Fatal Push; Culling Ritual; Nihil Spellbomb; Ashiok, Dream Render; Vexing Bauble; Shatter Assumptions; Break the Ice
Phase windows: between games
Runtime cues: sideboard candidate plans and revealed matchup label
Use when: Select sideboard configuration from legal registered swaps after Game 1 or Game 2.
Avoid when: The proposed plan cuts too many early creatures for the engine, brings narrow hate without observed targets, or violates registered 75 preservation.
Instructions: Add Fatal Push and Culling Ritual against creature or small-permanent boards, Nihil Spellbomb and Ashiok, Dream Render against graveyard/search plans, Vexing Bauble against free or alternate-cost spell plans, Break the Ice against vulnerable mana, and Shatter Assumptions only when its text and matchup target are verified.
Pilot skill floor: light-model
No-API allowed: no

### Policy: Graveyard Hate Activation Gate
Priority: Medium
Decision families: interaction, priority
Cards: Nihil Spellbomb; Ashiok, Dream Render
Phase windows: opponent graveyard setup, response windows, main phases
Runtime cues: legal Nihil Spellbomb activation; legal Ashiok, Dream Render activation
Use when: Opponent graveyard or search action is visible and the hate action can remove or prevent a meaningful resource.
Avoid when: Activating consumes mana or loyalty without affecting a visible graveyard, search, or recursion line.
Instructions: Fire Nihil Spellbomb before the opponent can use visible graveyard resources; hold it if waiting captures a larger public graveyard with no immediate risk. Use Ashiok, Dream Render when search prevention or graveyard exile matters to the revealed matchup.
Pilot skill floor: light-model
No-API allowed: no

### Policy: Culling Ritual Sweep Gate
Priority: High
Decision families: interaction, priority, mana
Cards: Culling Ritual; Marionette Apprentice; Gravecrawler; Shambling Ghast; Warren Soultrader; Orcish Bowmasters
Phase windows: main phase before or after combat
Runtime cues: legal cast Culling Ritual
Use when: Decide whether Culling Ritual improves the visible board enough to justify destroying low-cost permanents, including your own.
Avoid when: It destroys the sacrifice engine or pressure without clearing opponent material or enabling a decisive follow-up.
Instructions: Count both sides' permanents and post-resolution mana before casting. Prefer it when it breaks opposing small boards, artifacts, enchantments, or tokens while leaving a follow-up spell or recursion path.
Pilot skill floor: light-model
No-API allowed: no
Light-model allowed: yes

### Policy: Narrow Hate Deployment
Priority: Medium
Decision families: priority, interaction
Cards: Vexing Bauble; Break the Ice; Shatter Assumptions; Fatal Push
Phase windows: early turns, response windows, main phases
Runtime cues: legal cast Vexing Bauble; legal cast Break the Ice; legal cast Shatter Assumptions; legal cast Fatal Push
Use when: A sideboard card has a visible target or matchup role from public information.
Avoid when: The card's target or text is uncertain and another legal action advances pressure or survival; Card text check required for Shatter Assumptions.
Instructions: Deploy Vexing Bauble before the opponent's free-spell turn if that plan is known. Use Break the Ice on vulnerable mana when tempo matters. Use Fatal Push on threats that alter combat or clock math.
