# Strategy Specifications
## Deck Name And Archetype

- Deck identity: Gruul Cascade is a Pauper ramp-stompy cascade deck built around enchanted `Forest` acceleration, land-denial tempo, and large cascade threats. The registered strategy name is `Gruul Cascade`; the supplied format is `pauper`; the active archetype and mechanic tags are `ramp`, `stompy`, and `cascade`.

- Deck count validation: the supplied main deck contains exactly 60 cards, and the supplied sideboard contains exactly 15 cards. The main deck count is validated from 4 `Annoyed Altisaur`, 4 `Utopia Sprawl`, 14 `Forest`, 4 `Boarding Party`, 3 `Eldrazi Repurposer`, 1 `Fang Dragon`, 2 `Generous Ent`, 3 `Malevolent Rumble`, 2 `Avenging Hunter`, 3 `Mwonvuli Acid-Moss`, 2 `Structural Distortion`, 4 `Thermokarst`, 3 `Wild Growth`, 1 `Wooded Ridgeline`, 4 `Writhing Chrysalis`, 2 `Mountain`, and 4 `Arbor Elf`.

- Sideboard count validation: the supplied sideboard count is validated from 3 `Breath Weapon`, 3 `Deglamer`, 2 `Gorilla Shaman`, 1 `Relic of Progenitus`, 2 `Suplex`, and 4 `Weather the Storm`. Sideboard plans in this guide must preserve the registered 75 and use exact balanced card counts when executable plans are provided.

- Stock status: treat this list as a hybrid stock-and-tuned Gruul Cascade shell, not a pure rogue deck. The stock core is `Arbor Elf`, `Utopia Sprawl`, `Wild Growth`, `Thermokarst`, `Mwonvuli Acid-Moss`, `Writhing Chrysalis`, `Boarding Party`, and `Annoyed Altisaur`; the tuned or list-specific pressure points are the exact split of `Eldrazi Repurposer`, `Malevolent Rumble`, `Avenging Hunter`, `Structural Distortion`, `Generous Ent`, and singleton `Fang Dragon`.

- Legality status: use this guide as a strategy document for the supplied Pauper decklist, but let Veles, Forge, and the configured card database decide actual legality and available actions at runtime. If the rules engine does not expose a cast, attack, block, target, sideboard, or payment action, the pilot must not infer that the action is legal from this guide.

- Card-text certainty status: tactical advice here should be conditional on the rules engine’s legal-action output, especially for `Eldrazi Repurposer`, `Malevolent Rumble`, `Fang Dragon`, `Generous Ent`, `Avenging Hunter`, `Structural Distortion`, `Breath Weapon`, `Deglamer`, `Suplex`, and `Weather the Storm`. Card text check required whenever an action depends on a specific mode, trigger, target class, alternate cost, or sideboard card timing that is not visible in the current legal action text.

- Mana identity: the deck is primarily green and uses red as a splash for cascade threats and sideboard interaction. `Forest` is the default engine land because `Arbor Elf`, `Utopia Sprawl`, and `Wild Growth` create the deck’s strongest starts from enchanted green sources; `Mountain` and `Wooded Ridgeline` are supporting red access, not the main plan.

- Role concern: the deck wins by moving ahead on mana and board before the opponent can convert cheap interaction or tempo into a stable game. The pilot should identify whether each game state asks for mana development, land denial, creature pressure, stabilization, or sideboard interaction before choosing among legal actions.

- Runtime opponent status: opponent information is archetype-level unless Veles provides a specific matchup guide, revealed cards, public game history, or sideboard-stage context. Do not assume hidden cards, exact hand composition, or matchup-specific sideboard cards unless they are visible, revealed, logged from public information, or supplied by the current decision request.

## Thesis

- Assemble enchanted `Forest` acceleration first, then convert that mana lead into land denial and oversized cascade pressure. The deck’s cleanest games start with `Arbor Elf`, `Utopia Sprawl`, or `Wild Growth`, then use `Thermokarst`, `Mwonvuli Acid-Moss`, or `Structural Distortion` to keep the opponent behind while `Boarding Party`, `Annoyed Altisaur`, `Writhing Chrysalis`, and `Avenging Hunter` end the game through combat.

- Win by making the opponent’s early turns inefficient, not by answering every permanent one-for-one. Prioritize plays that create a durable mana advantage, remove the opponent from key colors, or put a large threat into play before their deck can double-spell, hold up interaction, or stabilize combat.

- Treat cascade as a pressure engine, not a random value bonus. When casting `Boarding Party` or `Annoyed Altisaur`, prefer board states where most likely cascade hits advance the same plan: more mana, more land pressure, more bodies, or relevant interaction. Do not delay a cascade threat merely because the cascade result is uncertain if the current board asks for a clock.

- Use land destruction as tempo, color denial, and threat protection. `Thermokarst` is strongest when it blocks a color, keeps the opponent off a key mana threshold, or buys a full attack step for a large creature; `Mwonvuli Acid-Moss` is strongest when it both attacks opposing mana and finds another `Forest` for enchanted-land scaling; `Structural Distortion` is a narrower interaction piece, so confirm legal targets and immediate value from the rules engine before relying on it.

- Do not play like a pure control deck, pure Ponza deck, or pure ramp deck. This list is not trying to lock the opponent indefinitely, sculpt a perfect hand, or wait for inevitability; it is trying to create a mana-and-board gap large enough that every later creature, cascade spell, or initiative trigger is hard to answer cleanly.

- Prioritize survival only when the opposing board can race or invalidate the mana plan. Against fast creature starts, `Writhing Chrysalis`, `Eldrazi Repurposer`, `Avenging Hunter`, sideboard `Breath Weapon`, `Suplex`, and `Weather the Storm` matter more than extra land destruction if the opponent already has enough battlefield pressure.

- Respect runtime legality and visible information over this guide. If Veles does not expose a cast, target, attack, block, payment, or sideboard action, do not infer it; if an action depends on exact text for `Eldrazi Repurposer`, `Malevolent Rumble`, `Fang Dragon`, `Generous Ent`, `Structural Distortion`, `Breath Weapon`, `Deglamer`, `Suplex`, or `Weather the Storm`, Card text check required and the tactical use remains conditional on legal action text.

## Role Package

- Mana module: `Forest`, `Arbor Elf`, `Utopia Sprawl`, `Wild Growth`, `Generous Ent`, `Wooded Ridgeline`, and `Mountain` form the acceleration and color-access package. Prioritize an enchanted `Forest` when it enables `Arbor Elf` untaps; use `Generous Ent` conditionally as a land-access tool when the legal action text offers that line and the hand needs mana more than another late threat.

- Threat module: `Writhing Chrysalis`, `Boarding Party`, `Annoyed Altisaur`, `Avenging Hunter`, `Eldrazi Repurposer`, `Generous Ent`, and `Fang Dragon` are the combat bodies. Lead with the threat that best fits the visible board: haste pressure from `Boarding Party`, reach/trample size from `Annoyed Altisaur`, stabilization and material from `Writhing Chrysalis`, initiative pressure from `Avenging Hunter`, and conditional utility from `Eldrazi Repurposer`, `Generous Ent`, or `Fang Dragon` when their legal modes are exposed.

- Payoff module: `Boarding Party` and `Annoyed Altisaur` are the defining cascade payoffs, while `Avenging Hunter` is the initiative payoff and `Writhing Chrysalis` is the board-dominance payoff. Prefer payoff deployment when the opponent is constrained on mana, when the payoff changes combat immediately, or when waiting risks discard, counterplay, or losing the tempo advantage.

- Engine module: `Arbor Elf` plus `Utopia Sprawl` or `Wild Growth` is the deck’s primary engine, and `Mwonvuli Acid-Moss` can extend it by finding a `Forest` while denying an opposing land. Protect this engine by sequencing untapped `Forest` access carefully and by avoiding unnecessary taps that strand a high-impact spell.

- Velocity module: `Malevolent Rumble`, `Generous Ent`, cascade from `Boarding Party`, and cascade from `Annoyed Altisaur` keep resources moving. Use velocity when the hand lacks the next land, threat, or stabilizer; avoid low-impact digging when a legal land-destruction spell or threat already advances the current role.

- Interaction module: `Thermokarst`, `Mwonvuli Acid-Moss`, `Structural Distortion`, sideboard `Breath Weapon`, sideboard `Deglamer`, sideboard `Gorilla Shaman`, sideboard `Relic of Progenitus`, and sideboard `Suplex` are the deck’s main ways to interfere. Aim interaction at mana bottlenecks, artifacts/enchantments, graveyard engines, or creatures that change the race; do not spend narrow sideboard cards on low-impact targets merely to use mana.

- Protection module: `Weather the Storm`, `Breath Weapon`, `Suplex`, large blockers from `Writhing Chrysalis`, and reach bodies such as `Annoyed Altisaur` or `Generous Ent` are the practical protection tools. Use them to preserve enough life and board position for cascade threats to matter, not as an excuse to abandon pressure.

- Recursion module: the registered list has no dedicated recursion engine. Treat graveyard contents mainly as public information for opposing threats, `Relic of Progenitus` decisions, and any legal `Malevolent Rumble` or card-specific action the engine exposes; Card text check required before assuming graveyard access.

- Sideboard module: `Breath Weapon` covers creature swarms when legal and correctly timed; `Deglamer` answers artifacts or enchantments; `Gorilla Shaman` pressures artifact mana and artifact-heavy boards; `Relic of Progenitus` attacks graveyard reliance; `Suplex` handles creature combat problems; `Weather the Storm` buys time against burn and fast damage decks. Each sideboard card should be added for a specific matchup pressure, not because it is generically castable.

## Primary Win Conditions

- Mana-aura cascade pressure is the default win path. Set up `Forest` plus `Utopia Sprawl` or `Wild Growth`, pair it with `Arbor Elf` when available, then deploy `Boarding Party` or `Annoyed Altisaur` before the opponent can stabilize; prioritize this line when the hand has acceleration, at least one payoff, and no immediate need to answer a lethal board.

- Execute cascade pressure by casting the first large legal threat that changes the current turn cycle. `Boarding Party` is the faster clock when haste damage matters now; `Annoyed Altisaur` is the better board-control threat when reach, trample, and size matter; do not hold cascade payoffs for perfect value if the opponent is constrained or tapped low.

- Protect cascade pressure by attacking the opponent’s mana before or alongside the threat. `Thermokarst` and `Mwonvuli Acid-Moss` should target lands that deny colors, delay sweepers, delay removal, or keep the opponent from double-spelling; prioritize this lock-tempo line when one land-destruction spell buys a full attack step or makes the cascade threat harder to answer.

- Win through `Writhing Chrysalis` board dominance when combat is contested. Use `Writhing Chrysalis` as the main stabilizer into pressure plan when the opponent has small or medium creatures, because it can create a board state where later `Boarding Party`, `Annoyed Altisaur`, `Avenging Hunter`, or `Generous Ent` attacks become favorable; Card text check required for exact token, counter, or mana details before choosing related legal actions.

- Win through initiative snowball with `Avenging Hunter` when the opponent cannot immediately reclaim combat. Prioritize `Avenging Hunter` when a 5-mana play is legal, the visible board can defend the initiative or force profitable attacks, and the opponent’s current pressure is not already lethal; avoid this line when taking initiative but losing it immediately gives the opponent the stronger next-turn engine.

## Secondary Win Conditions

- Use land-destruction tempo as a secondary soft-lock when threats are delayed. Chain `Thermokarst`, `Mwonvuli Acid-Moss`, and conditional `Structural Distortion` to keep the opponent below key mana thresholds, then convert the extra turns into any large body; prioritize this path when the hand has multiple land-interaction spells but only one payoff or when opposing colors are visibly fragile.

- Use value bodies as fallback pressure when cascade is unavailable or answered. `Eldrazi Repurposer`, `Generous Ent`, `Fang Dragon`, and `Avenging Hunter` can win by occupying combat and forcing blocks, but Card text check required for `Eldrazi Repurposer`, `Generous Ent`, and `Fang Dragon` exact modes before assuming utility beyond the legal action text.

- Use `Malevolent Rumble` as the recovery and setup line when the hand lacks the next land, payoff, or stabilizer. Prioritize it over low-impact pass turns when digging can find acceleration, a large creature, or land interaction; Card text check required before relying on any graveyard, token, or selection detail not exposed by Veles.

- Use red access as a closing branch, not the main plan. `Boarding Party` is the main red payoff, `Fang Dragon` may provide late pressure or conditional utility, and `Structural Distortion` may contribute damage only if legal action text confirms that outcome; do not damage-race with red cards unless the visible board and legal actions show a concrete clock.

- Use `Generous Ent` as either mana access or a late body depending on the hand. If the legal action offers a land-search or cycling-style mode and the hand needs `Forest`, `Mountain`, or stable mana more than another creature, choose the setup branch; if mana is already abundant and the board needs a large blocker or attacker, preserve it as a threat.

## Emergency Lines

- When behind on life, stop prioritizing extra land destruction unless it prevents immediate lethal or unlocks a stabilizer. Shift to `Writhing Chrysalis`, `Avenging Hunter`, large blockers from `Annoyed Altisaur` or `Generous Ent`, and post-board `Weather the Storm`, `Breath Weapon`, or `Suplex` only when legal action text and visible board make the defensive use relevant.

- When behind on board, trade tempo for survival before rebuilding the mana gap. Cast or sequence `Writhing Chrysalis`, `Eldrazi Repurposer`, `Avenging Hunter`, `Annoyed Altisaur`, or sideboard creature interaction over another ramp aura if the opponent’s next attack threatens to invalidate the hand; use `Breath Weapon` only when the visible creature board and legal action text support the sweep.

- When behind on cards, prefer cascade and selection over one-for-one land pressure. `Boarding Party`, `Annoyed Altisaur`, and `Malevolent Rumble` are the main ways to rebuild; avoid spending `Thermokarst` on a land that does not constrain the opponent if the hand needs a threat or selection spell to matter.

- When behind on mana, rebuild with `Forest`, `Utopia Sprawl`, `Wild Growth`, `Arbor Elf`, `Mwonvuli Acid-Moss`, and conditional `Generous Ent` land access. Do not keep tapping out for narrow interaction if the visible path to winning requires reaching six or seven mana first.

- When cascade threats are removed, win by stacking medium pressure and denying recovery. Combine `Writhing Chrysalis`, `Avenging Hunter`, `Eldrazi Repurposer`, `Generous Ent`, `Fang Dragon`, and land destruction to force awkward blocks and prevent the opponent from turning removal into a full reset.

- When the opponent has graveyard, artifact, enchantment, or swarm engines post-board, use the emergency answer only for the engine that matters. `Relic of Progenitus`, `Deglamer`, `Gorilla Shaman`, `Breath Weapon`, and `Suplex` are not alternate win conditions by themselves; they buy enough time for the primary large-creature plan to finish the game.

## Resource Model

- Life is a tempo buffer for reaching cascade mana, not a resource to spend blindly. Accept early damage when it lets `Forest`, `Utopia Sprawl`, `Wild Growth`, and `Arbor Elf` produce a faster `Boarding Party`, `Annoyed Altisaur`, or `Writhing Chrysalis`; switch to blocking or defensive sideboard cards once the opponent's visible attack threatens to make the next payoff too late.

- Hand size converts into mana velocity when it contains acceleration plus payoffs. Keep hands that turn one or two cards into multiple extra mana over the next two turns; mulligan or treat as risky hands that contain only expensive threats, only land destruction, or red cards without green acceleration.

- Mana is the deck's main advantage engine. Spend early turns making enchanted `Forest` mana and preserving green access, then convert surplus mana into cascade bodies, land destruction, and stabilizing creatures before the opponent can double-spell through the pressure.

- Board presence must become pressure after the first stabilizing turn. `Writhing Chrysalis`, `Eldrazi Repurposer`, `Avenging Hunter`, `Generous Ent`, `Boarding Party`, and `Annoyed Altisaur` should be judged by whether they stop the next attack, force damage, defend initiative, or enable a lethal turn; Card text check required for exact `Writhing Chrysalis`, `Eldrazi Repurposer`, and `Generous Ent` utility beyond visible legal actions.

- Graveyard value is mostly public context unless `Malevolent Rumble`, `Relic of Progenitus`, or an opposing graveyard deck makes it material. Do not assume graveyard recursion or graveyard payoff from this deck unless the rules engine exposes it; use `Relic of Progenitus` post-board to buy time against visible graveyard dependence, not as a default tempo play.

- Exile matters for tracking answered permanents and sideboard effects. `Structural Distortion`, `Deglamer`, and `Relic of Progenitus` may move cards out of normal resource loops, but Card text check required before assuming the exact destination, damage, shuffle, or replacement outcome unless Veles shows it in legal action text.

- Lands are both mana base and disruption targets. Your own `Forest` count enables `Utopia Sprawl`, `Wild Growth`, `Arbor Elf`, `Mwonvuli Acid-Moss`, and likely `Generous Ent` setup lines; opposing lands are priority targets when `Thermokarst`, `Mwonvuli Acid-Moss`, or `Structural Distortion` can deny a color, a key mana threshold, or a recovery turn.

- Sacrifice fodder is conditional, not assumed. If `Writhing Chrysalis` or `Malevolent Rumble` creates visible expendable material, use it only when the rules engine offers a legal mana, cost, block, or sacrifice action; do not plan around hidden token text without a card text check.

- Tempo is won by making the opponent's next turn smaller than yours. Prefer land destruction over another threat when it strands visible mana, delays a sweeper, or protects an already meaningful attacker; prefer a threat over land destruction when the opponent can still affect the board and you need damage or blockers now.

- Information is a constraint on confidence. Use revealed hands, public graveyards, known sideboard cards, and previous game observations, but never choose as if the opponent has an exact hidden answer unless it is revealed or strongly implied by public play patterns.

- Sideboard bullets convert narrow pressure into time for the large-creature plan. `Breath Weapon` answers small-creature boards when legal and effective, `Deglamer` answers important artifacts or enchantments, `Gorilla Shaman` pressures artifact mana or cheap artifacts, `Relic of Progenitus` checks graveyards, `Suplex` answers creature problems, and `Weather the Storm` buys life against burst damage.

## Mana Guide

- Green mana is mandatory early because the deck's best starts depend on `Forest`, `Utopia Sprawl`, `Wild Growth`, and `Arbor Elf`. Prefer opening hands with `Forest` plus an aura or `Arbor Elf`; hands with only `Mountain`, `Wooded Ridgeline`, or red payoff cards need a clear legal route to green before they are keepable.

- Enchant `Forest` before non-Forest lands unless a visible legal action requires another land. `Utopia Sprawl` and `Wild Growth` should usually go on a `Forest` that `Arbor Elf` can untap, because that pairing creates the explosive turn-three and turn-four mana needed for `Mwonvuli Acid-Moss`, `Avenging Hunter`, `Boarding Party`, and `Annoyed Altisaur`.

- Choose `Utopia Sprawl` color from the hand and sideboard plan. Name or preserve red when `Boarding Party`, `Fang Dragon`, `Structural Distortion`, `Breath Weapon`, or `Gorilla Shaman` matters; choose green when the hand needs multiple green spells, land destruction chains, or stable access to `Annoyed Altisaur`, `Generous Ent`, `Writhing Chrysalis`, and `Avenging Hunter`.

- Play tapped lands only when the current turn does not need untapped green. `Wooded Ridgeline` is acceptable as early fixing when the hand already has a turn-one or turn-two plan accounted for; avoid letting it delay `Utopia Sprawl`, `Wild Growth`, `Arbor Elf`, or a key land-destruction turn.

- Sequence land drops to maximize known legal actions before speculative ones. If a selection spell such as `Malevolent Rumble` is legal before the land drop and could reveal or influence the best land for turn, consider waiting on the land drop; if casting the spell requires the land now or if the hand already has the needed next land, play the land first to preserve tempo.

- Play land before combat or priority actions when the mana changes legal spell choices. Holding a land is only useful when Veles exposes a selection, bluff, or discard-related reason; this deck usually gains more from representing and using mana than from concealing a land.

- Preserve red only when it changes this turn or the next turn. Do not overvalue `Mountain` if it weakens the enchanted-`Forest` engine, but do not tap the only red source casually when `Boarding Party`, `Structural Distortion`, `Fang Dragon`, or post-board red cards are the next meaningful action.

- Keep mana-source choices aligned with the next spell chain. When paying generic costs, spend redundant untapped sources first and preserve enchanted `Forest` plus `Arbor Elf` loops if they create additional mana after the payment; when floating mana is offered, choose colors that match visible follow-up actions rather than generic maximum mana.

- Mulligan mana-light hands without acceleration unless the hand has a concrete two-turn recovery line. One-land hands need `Forest` plus `Utopia Sprawl`, `Wild Growth`, `Arbor Elf`, or a legal land-search/cycling route from `Generous Ent`; expensive hands without early green action should be sent back even if the spells are powerful.

- Mulligan mana-heavy hands when they cannot convert mana into pressure or disruption. Multiple lands plus no `Utopia Sprawl`, `Wild Growth`, `Arbor Elf`, `Malevolent Rumble`, `Thermokarst`, `Mwonvuli Acid-Moss`, or payoff is a low-agency keep; this deck needs mana and a conversion card, not mana alone.

## Mulligan Guide

- Strong keep: `Forest` plus `Utopia Sprawl` or `Wild Growth` plus `Arbor Elf` and any conversion spell is the premium start. Keep hands like `Forest`, `Forest`, `Utopia Sprawl`, `Arbor Elf`, `Thermokarst`, `Boarding Party`, `Annoyed Altisaur` because they can ramp, disrupt mana, then cascade.

- Strong keep: two or three lands with early green acceleration and land destruction is a keep even without a cascade threat. `Forest`, `Forest`, `Wooded Ridgeline`, `Wild Growth`, `Thermokarst`, `Mwonvuli Acid-Moss`, `Writhing Chrysalis` is functional because it attacks mana while building toward a board stabilizer.

- Medium keep: `Malevolent Rumble` plus stable green mana is acceptable when the hand lacks `Arbor Elf` or an aura but has a clear turn-three or turn-four play. Treat `Malevolent Rumble` as a smoothing card only through visible legal action text; Card text check required for exact output beyond selection or material shown by Veles.

- Medium keep: expensive hands with `Generous Ent`, `Avenging Hunter`, `Boarding Party`, or `Annoyed Altisaur` are keepable only when the first two turns produce extra mana or find lands. Do not keep a pile of payoffs because the cards are individually strong.

- Risky keep: one `Forest` with `Utopia Sprawl` and no second land is matchup- and draw-dependent. Keep more often on the draw or against slow decks; ship more often on the play against fast red, Faeries pressure, or artifact starts where missing land two loses the game.

- Automatic ship: hands without green mana or without a credible route to green are not keepable. `Mountain`, `Wooded Ridgeline`, `Boarding Party`, `Fang Dragon`, `Structural Distortion`, `Annoyed Altisaur`, `Avenging Hunter` is a trap because the first relevant legal action may arrive too late.

- Automatic ship: hands with lands but no acceleration, no `Malevolent Rumble`, no `Thermokarst`, no `Mwonvuli Acid-Moss`, and no castable stabilizer should be sent back. This deck needs mana plus a conversion card, not just mana.

- Matchup-dependent keep: land-destruction-heavy hands are strong against Tron, multicolor control, and slow setup decks but weaker against low-curve creature swarms. `Thermokarst`, `Mwonvuli Acid-Moss`, and `Structural Distortion` should be kept when denying lands matters more than blocking immediately; Card text check required for exact `Structural Distortion` secondary effects.

- Matchup-dependent keep: creature-heavy hands with `Writhing Chrysalis`, `Eldrazi Repurposer`, `Avenging Hunter`, or `Generous Ent` are better against aggro than against combo if they lack disruption. Card text check required for exact `Eldrazi Repurposer`, `Writhing Chrysalis`, and `Generous Ent` utility beyond legal actions shown.

- Play/draw rule: on the play, prioritize `Forest` plus turn-one acceleration because turn-two `Thermokarst` or turn-three `Mwonvuli Acid-Moss` can steal a full turn. On the draw, tolerate slightly slower hands with interaction or selection because the extra card improves land-drop reliability.

- Trap hand: `Forest`, `Mountain`, `Boarding Party`, `Annoyed Altisaur`, `Fang Dragon`, `Avenging Hunter`, `Generous Ent` looks powerful but lacks the early engine. Ship unless `Generous Ent` or another visible action supplies a legal land-finding route soon enough for the matchup.

## Turn Arc

- Turn 1: play `Forest` and cast `Utopia Sprawl`, `Wild Growth`, or `Arbor Elf` when legal. Prefer aura plus untapped `Forest` setup when it enables `Arbor Elf` loops; prefer `Arbor Elf` when the hand has a second-turn aura or land-destruction line.

- Turn 1 deviation: play `Wooded Ridgeline` only when no untapped `Forest` acceleration is available or when red fixing is required for a known near-term `Boarding Party`, `Structural Distortion`, `Fang Dragon`, or sideboard card. Do not delay a legal `Utopia Sprawl` or `Wild Growth` without a visible payoff.

- Turn 2: deploy the second acceleration piece or cast `Thermokarst` if the mana supports it and the target land matters. If `Arbor Elf` plus enchanted `Forest` is online, choose the line that creates the largest turn-three branch: `Mwonvuli Acid-Moss`, `Avenging Hunter`, `Writhing Chrysalis`, or cascade setup.

- Turn 2 deviation: cast `Malevolent Rumble` when the hand needs land, a stabilizing permanent, or a bridge to the next mana threshold. Avoid using it over a strong land-destruction spell when the opponent’s visible mana is fragile and denying a land changes their next turn.

- Turn 3: prioritize `Mwonvuli Acid-Moss` or `Thermokarst` when the opponent depends on a color, a bounce land, Tron assembly, or a key fourth mana. Prioritize `Writhing Chrysalis`, `Eldrazi Repurposer`, or `Avenging Hunter` when the board requires a blocker, initiative pressure, or material before more mana denial.

- Turn 3 deviation: preserve red access if `Boarding Party`, `Structural Distortion`, or `Fang Dragon` is the next high-impact legal play. Do not tap the only red source for marginal sequencing when it strands the cascade or answer line.

- Turns 4-5: cast `Boarding Party` or `Annoyed Altisaur` when the board is stable enough for cascade pressure. If the opponent is constrained on mana, continue `Thermokarst`, `Mwonvuli Acid-Moss`, or `Structural Distortion` before committing another expensive threat.

- Turns 4-5 deviation: choose `Avenging Hunter` when taking or defending initiative changes combat math more than another large body. Choose `Generous Ent` lines only according to visible legal actions; Card text check required before assuming exact land-search or creature-mode value.

- Late game: chain cascade threats and make every land-destruction spell answer a real recovery path. `Boarding Party`, `Annoyed Altisaur`, `Writhing Chrysalis`, `Avenging Hunter`, `Fang Dragon`, and `Generous Ent` should be sequenced by lethal pressure, blocker needs, and exposure to visible removal.

- Late-game deviation: stop attacking mana when the opponent already has enough lands and the legal play must answer battlefield pressure. In those spots, use creatures, combat, and any legal `Structural Distortion` or `Suplex`-style post-board answer to stabilize before returning to the denial plan.

## Card Roles

- `Arbor Elf`: Treat `Arbor Elf` as the deck's cleanest turn-one accelerator when it can untap an enchanted `Forest` on the following turn. Cast it early over slower setup when the hand already contains `Utopia Sprawl` or `Wild Growth`, because the creature turns one enchanted land into a cascade timetable. Protect its usefulness by sequencing lands so it has an actual `Forest` to untap; a hand that opens on `Mountain` or `Wooded Ridgeline` may strand it. Do not trade `Arbor Elf` in combat unless blocking preserves survival or the mana engine is already redundant. Against removal-heavy decks, expect it to die and keep hands that can still operate if the first accelerator is answered.

- `Utopia Sprawl`: Use `Utopia Sprawl` as the highest-value land aura because it fixes color while accelerating. Put it on an untapped `Forest` whenever possible, especially when `Arbor Elf` is present or likely to matter next turn. Name the color that unlocks the next legal spell, not the abstract best color; green usually supports `Thermokarst`, `Mwonvuli Acid-Moss`, `Writhing Chrysalis`, and `Annoyed Altisaur`, while red matters for `Boarding Party`, `Structural Distortion`, `Fang Dragon`, `Breath Weapon`, and `Gorilla Shaman`. Avoid enchanting a land that is exposed to known land destruction only if another legal line preserves the same acceleration without losing tempo. Do not choose colors from memory when Veles exposes a color-choice prompt; use visible hand, battlefield, and legal actions.

- `Wild Growth`: Use `Wild Growth` as redundant acceleration that makes `Arbor Elf` explosive but does not fix color by itself. Cast it early when it advances from two mana to four or from four mana to six, because those thresholds create `Mwonvuli Acid-Moss`, `Avenging Hunter`, `Boarding Party`, and `Annoyed Altisaur` turns. Prefer putting `Wild Growth` on a `Forest` that `Arbor Elf` can untap unless the rules engine only offers another legal attachment. Do not over-prioritize a second aura when a legal `Thermokarst` can cut the opponent off a key color or Tron piece. Against decks with bounce or land destruction, diversify only when visible risk and legal choices make that safer than maximizing mana.

- `Thermokarst`: Treat `Thermokarst` as an early tempo weapon, not a late-game ritual. Cast it when destroying a land changes the opponent's next turn: cutting a color, delaying a four-mana play, breaking Tron, punishing a bounce land, or keeping the opponent from double-spelling. Hold it when the opponent already has enough mana and the board demands a stabilizer such as `Writhing Chrysalis`, `Eldrazi Repurposer`, `Avenging Hunter`, or `Breath Weapon` post-board. Choose targets from visible lands only; do not assume hidden hand contents. Against aggro, use `Thermokarst` selectively because spending a turn on mana denial while taking damage can lose the race.

- `Mwonvuli Acid-Moss`: Use `Mwonvuli Acid-Moss` as the bridge between disruption and your own six-mana turns. Prioritize it over `Thermokarst` when the extra land materially enables `Boarding Party`, `Annoyed Altisaur`, `Fang Dragon`, or double-spell turns. Target a land that constrains the opponent's next meaningful action, especially Tron lands, bouncelands, splash colors, or a fourth land that would unlock sweepers and large threats. Do not cast it just because it is four mana if a creature is needed to survive combat. Card text check required for exact search restrictions and any land-entry details; follow rules-engine prompts for land selection.

- `Malevolent Rumble`: Use `Malevolent Rumble` as smoothing and setup when the hand needs a land, permanent, body, or missing engine piece. Cast it before committing expensive threats when it improves the next two turns more than a speculative land-destruction spell. Do not cast it ahead of a decisive `Thermokarst` or `Mwonvuli Acid-Moss` window against a mana-fragile opponent. Card text check required for exact selection, token, graveyard, and permanent rules; choose only from legal revealed options. In grindy matchups, value it as a way to keep cascade chains stocked with follow-up permanents.

- `Writhing Chrysalis`: Treat `Writhing Chrysalis` as the main stabilizing body and board-scaling threat. Cast it when the opponent is pressuring with creatures, when you need blockers before cascading, or when a large body changes attacks and blocks. Card text check required for exact token, reach, growth, and mana-related wording; use only legal actions shown by Veles. Do not delay it for land destruction if taking another attack puts you under a short clock. Against Faeries, fast red, and go-wide decks, its defensive role often matters more than immediate cascade setup.

- `Eldrazi Repurposer`: Use `Eldrazi Repurposer` as a midgame creature that supports the mana-and-material plan when the board needs presence before seven-mana threats. Card text check required for exact abilities, token handling, and resource conversion; keep tactical use conditional on visible legal actions. Cast it when it blocks profitably, produces material, or helps bridge to cascade without taking a full turn off. Do not treat it as interchangeable with `Writhing Chrysalis`; if the immediate issue is combat survival, choose the creature whose visible stats and legal actions best stabilize.

- `Avenging Hunter`: Use `Avenging Hunter` when initiative pressure or dungeon progress is worth exposing a five-mana creature. Cast it on a board where you can defend the initiative or when taking initiative forces the opponent to answer you instead of advancing their plan. Avoid casting it into a battlefield where the opponent can immediately attack back and steal the initiative without cost. Against slow control and Tron, it can be a strong value threat after land denial. Against creature swarms, it is weaker unless it blocks and preserves the initiative.

- `Boarding Party`: Treat `Boarding Party` as the haste cascade threat that converts ramp into immediate pressure. Cast it when red mana is available and the cascade hit is likely to improve the board, disrupt mana, or add another threat. Do not fire it into a board where you must first answer lethal pressure unless the legal cascade line is your only stabilizing route. Because cascade is rules-engine controlled, evaluate the cast before the trigger, then follow the resulting legal action prompts honestly. Against control, `Boarding Party` pressures planes of interaction by demanding an answer while adding another spell.

- `Annoyed Altisaur`: Use `Annoyed Altisaur` as the largest cascade payoff and late-game body. Cast it when you can afford a seven-mana commitment and a large attacker or blocker materially changes the game. Hold it when spending all mana walks into visible stack interaction or leaves you dead to the current board. Its cascade may hit acceleration late, so judge the body plus random legal cascade outcome rather than assuming a specific hit. Against removal-heavy decks, sequence `Boarding Party`, `Avenging Hunter`, or land denial first when that better taxes answers.

- `Generous Ent`: Treat `Generous Ent` as flexible top-end or land access depending on the legal actions Veles exposes. Card text check required for exact land-search, cycling, reach, and creature text; do not assume a mode unless it appears as a legal action. Use the land-finding line when the hand needs to hit cascade mana or red access. Use the creature line when a large stabilizer matters more than future fixing. Against aggro, the defensive body can be more important than squeezing extra mana efficiency.

- `Fang Dragon`: Use `Fang Dragon` as a singleton high-end red threat or utility card only when its visible legal action solves the current board better than another cascade threat. Card text check required for exact abilities and any alternate mode. Preserve red mana if `Fang Dragon` is the planned stabilizer or finisher. Do not build early turns around drawing it; it is a payoff for successful ramp, not a keep reason by itself.

- `Structural Distortion`: Use `Structural Distortion` as targeted disruption when its legal target matters more than adding board material. Card text check required for exact target types, exile or damage clauses, and artifact/land restrictions. Prioritize it against artifact lands, affinity infrastructure, Tron recovery pieces, or red-relevant sideboard targets when Veles confirms legality. Avoid casting it into low-impact targets while behind on creatures unless no stabilizing play is available.

- `Forest`, `Mountain`, and `Wooded Ridgeline`: Treat `Forest` as the engine land because it carries `Utopia Sprawl`, `Wild Growth`, and `Arbor Elf` sequencing. Use `Mountain` and `Wooded Ridgeline` to unlock red payoffs, but do not let red fixing delay the first green acceleration unless the hand otherwise cannot function. Preserve land drops because this deck's expensive spells reward raw mana even after the first accelerator dies.

## Interaction Priorities

- Land denial priority: Use `Thermokarst`, `Mwonvuli Acid-Moss`, and `Structural Distortion` on lands that stop the opponent's next high-impact turn, not merely on the first legal land. Prioritize Tron pieces before Tron is assembled, bouncelands before they generate repeated advantage, artifact lands against Affinity, splash-color sources that unlock removal or sweepers, and the land that reaches four or five mana for control stabilizers.

- Stabilization priority: Use creature-impacting sideboard actions before land denial when the visible board presents a short clock. `Breath Weapon` should answer go-wide small creatures when Veles confirms the legal action and damage pattern; Card text check required for exact creature restrictions and damage amount. `Suplex` should be reserved for a creature whose removal changes combat or preserves initiative; Card text check required for exact fight, target, and size restrictions.

- Artifact and enchantment priority: Use `Deglamer`, `Gorilla Shaman`, and `Structural Distortion` on engines before replaceable material. Against Affinity, prioritize mana-producing artifact lands, cost-reduction infrastructure, and artifacts that enable lethal or card-flow loops; against Bogles or enchantment-based decks, prioritize the aura or enchantment whose removal changes combat math or shuts off the engine. Ignore low-impact artifacts if destroying a land or casting `Writhing Chrysalis` prevents more damage.

- Graveyard priority: Use `Relic of Progenitus` when the opponent's graveyard is a visible resource for lethal, recursion, delve, flashback, or a known engine, rather than cycling it casually. Against decks with little graveyard reliance, treat `Relic of Progenitus` as low priority unless the legal draw/exile line is free from tempo cost. Do not exile your own graveyard for speculative value if `Malevolent Rumble` or future card text makes the graveyard relevant; Card text check required for exact graveyard dependencies.

- Bait priority: Lead with redundant ramp, land destruction, `Avenging Hunter`, or `Boarding Party` when the opponent represents counterspells or instant-speed removal and the hand contains a more decisive `Annoyed Altisaur`, `Writhing Chrysalis`, or follow-up cascade threat. Do not bait by wasting a scarce red source or abandoning survival; the bait spell must still advance mana, pressure, or disruption if it resolves.

- Counter/discard/bounce priority: This registered list has no normal counterspell, discard spell, or bounce spell, so never assume those options exist. If Veles exposes an unusual legal counter, discard, or bounce action from a copied effect, cascade result, or opponent-controlled prompt, use it on the visible spell, card, or permanent that most directly stops lethal, breaks your ramp engine, or prevents the next cascade turn.

- Ignore priority: Ignore small creatures, incidental life gain, and non-engine permanents when your visible line produces a faster `Boarding Party` or `Annoyed Altisaur` turn and your life total is not under a short clock. Change this rule against fast red, Faeries, tokens, and go-wide decks, where small bodies can force bad blocks before cascade stabilizes.

## Combat And Trading Rules

- Attack priority: Attack when the damage advances a two-turn clock or forces blocks that protect your later cascade threats. `Boarding Party` should pressure immediately when haste damage is safe, while `Annoyed Altisaur`, `Generous Ent`, `Fang Dragon`, and large `Writhing Chrysalis` bodies should attack only when losing a blocker does not expose you to lethal or initiative loss.

- Block priority: Block aggressively when preserving life buys a cascade turn, a `Writhing Chrysalis` turn, or a sideboard stabilizer turn. Do not preserve a medium creature for future value if taking the hit puts you within burn range, flying-lethal range, or a forced chump-block sequence.

- Trade priority: Trade `Arbor Elf`, tokens, or smaller setup creatures for real pressure once the mana engine is already functioning or the creature would not survive the next combat. Preserve `Arbor Elf` early when it untaps an enchanted `Forest` and the extra mana enables `Mwonvuli Acid-Moss`, `Boarding Party`, or `Annoyed Altisaur` before the opponent can stabilize.

- Engine preservation: Protect enchanted `Forest` plus `Arbor Elf` sequencing by avoiding attacks or blocks that sacrifice the untapper for minor damage. Once you have enough lands and enchantments to cast top-end threats without `Arbor Elf`, convert it into a blocker or trade when life total matters more than extra mana.

- `Writhing Chrysalis` rule: Treat `Writhing Chrysalis` as the default combat anchor against creature decks. Keep it back when its visible stats stop multiple attackers, attack with it when the opponent cannot profitably crack back, and do not trade it for a replaceable creature unless the trade prevents lethal or protects initiative.

- Initiative rule: Attack or block around `Avenging Hunter` by asking whether you can keep the initiative after the opponent's next combat. Avoid a tempting attack if it leaves no profitable block and lets the opponent steal initiative for free; take a trade if it keeps initiative progress under your control.

- Archetype changes: Against fast red and go-wide decks, life total is a scarce resource and blocking starts earlier. Against Tron and control, pressure matters more, so attack with haste and large bodies unless visible interaction or a race-back punishes it. Against Affinity, respect large artifact creatures and flying clocks; use combat to force trades only after artifact interaction or land denial has weakened their mana. Against graveyard combo, attack quickly but keep blockers if the opponent can pivot to a creature kill from visible board state.

## Selection And Tutor Rules

- `Generous Ent` selection: Use `Generous Ent` as the cleanest pseudo-tutor when the hand needs a land more than a seven-mana body. Its landcycling should normally find `Forest` when `Arbor Elf`, `Utopia Sprawl`, `Wild Growth`, `Thermokarst`, or `Mwonvuli Acid-Moss` need green density; choose `Mountain` or `Wooded Ridgeline` only when a visible red requirement for `Boarding Party`, `Fang Dragon`, `Breath Weapon`, or `Gorilla Shaman` matters more than accelerating enchanted `Forest` lines. Card text check required for exact landcycling cost and permitted land subtype.

- `Mwonvuli Acid-Moss` selection: Treat the search half of `Mwonvuli Acid-Moss` as ramp attached to disruption, not as optional deck thinning. Find `Forest` when the next turn needs maximum green or an enchantable untap target, and find `Wooded Ridgeline` only if the red source is required for a known follow-up and entering tapped will not cost the next decisive spell. Do not cast `Mwonvuli Acid-Moss` just to search if the target land is strategically low-impact and another legal action stabilizes the board.

- `Malevolent Rumble` selection: Cast `Malevolent Rumble` when the hand needs a permanent, land drop, or body-producing setup more than immediate land destruction or a threat. Card text check required for exact reveal count, eligible card types, graveyard movement, and token creation; choose the revealed card that fixes the current bottleneck first: missing land, missing red source, top-end cascade threat, then stabilizing creature.

- Cascade selection discipline: `Annoyed Altisaur` and `Boarding Party` cascade choices are rules-engine-driven, so select only the legal cast/pass action Veles exposes. Cast the cascade hit when it advances mana, land denial, board presence, or survival; pass only when casting the hit is visibly harmful, such as removing your own critical permanent, wasting a sideboard answer with no target that matters, or exposing a worse stack sequence.

- Land-drop timing: Make the land drop before selection only when the extra mana changes the legal action set or pays for a known follow-up. Delay the land drop when `Malevolent Rumble`, `Generous Ent`, or a cascade sequence may reveal or require a better land choice, especially when choosing between `Forest`, `Mountain`, and `Wooded Ridgeline` affects `Utopia Sprawl`, `Arbor Elf`, and red spell access.

- Aura-color selection: With `Utopia Sprawl`, name green by default when the hand is green-heavy or depends on `Arbor Elf` plus enchanted `Forest`; name red when the hand already has green stability and lacks red for `Boarding Party`, `Fang Dragon`, `Breath Weapon`, or `Gorilla Shaman`. `Wild Growth` does not choose a color; preserve the enchanted `Forest` as the premier untap target when possible.

## Priority And Stack Rules

- Main-phase priority: Spend priority proactively when a legal action develops mana, destroys a key land, or commits a major threat before the opponent reaches their next stabilizing turn. Passing with unused mana is correct only when the available legal actions are low impact, the hand needs to conceal a sideboard instant, or the board requires holding a response window.

- Cascade stack rule: Let your own `Annoyed Altisaur` or `Boarding Party` cascade trigger resolve unless Veles exposes a specific legal response that prevents lethal or protects the cascade spell from visible interaction. After the cascade hit is revealed, choose the legal cast action when the hit is beneficial on board; do not assume you can reorder or choose hidden library cards.

- Land-destruction timing: Cast `Thermokarst`, `Mwonvuli Acid-Moss`, or `Structural Distortion` before combat or before giving the opponent another untap when the target land enables their next high-impact play. Hold land destruction only when a visible creature, stack spell, or lethal clock demands immediate stabilization instead.

- Instant-speed response windows: This maindeck has limited true instant interaction, so do not represent responses that Veles does not list. After sideboarding, use `Deglamer`, `Breath Weapon`, `Weather the Storm`, `Relic of Progenitus`, and any exposed activated abilities only in legal windows where the visible target or life swing matters; Card text check required for each exact timing, target, and effect.

- `Relic of Progenitus` timing: Activate `Relic of Progenitus` before the opponent converts graveyard cards into damage, recursion, delve, flashback, or a combo resource. Do not cash it in merely because priority is available if the opponent's graveyard is not currently a resource and your own graveyard may still matter for `Malevolent Rumble` consequences or future public information.

- `Weather the Storm` timing: Hold `Weather the Storm` until the storm count and life swing matter for survival or racing. Card text check required for exact storm behavior; do not fire it early against low pressure unless the legal window would otherwise disappear or the opponent threatens lethal before your next priority.

- Combat priority: Use post-attackers and post-blockers priority to convert mana into survival only when Veles exposes a legal spell or ability that changes combat math. `Breath Weapon`, `Suplex`, `Fang Dragon`, or sacrifice-token mana lines may matter in these windows, but choose them only from legal actions and only when they prevent lethal, preserve initiative, or turn a bad combat into a stable one.

- Optional payments and triggers: Pay optional costs only when they improve the current plan more than preserving mana for cascade, land destruction, or interaction. Decline optional payments that consume the red or green source needed for a pending target, sideboard answer, or next-turn top-end spell.

## Sideboard Map

- Sideboard principle: Treat the sideboard as role correction, not as a new deck. `Gruul Cascade` should keep its core of `Arbor Elf`, `Utopia Sprawl`, `Wild Growth`, land destruction, `Writhing Chrysalis`, `Boarding Party`, and `Annoyed Altisaur` unless the matchup makes one of those packages visibly low impact. Sideboard actions must preserve a legal 60-card deck and should be applied only from registered cards.

- `Breath Weapon` role: Bring `Breath Weapon` against creature swarms, one-toughness battlefields, token engines, Faeries-style boards, Rally shells, and fast red boards where a small sweeper buys the turn needed for cascade threats. Card text check required for exact damage, timing, and whether it affects each creature subset; use it tactically only when Veles shows a legal cast and the visible board makes the life or material swing matter. `Breath Weapon` is poor against low-creature control, large-creature stompy mirrors, combo decks with few bodies, and boards where it mainly damages your own `Arbor Elf` while not changing the opponent's clock.

- `Deglamer` role: Bring `Deglamer` against artifact lands, Affinity threats, important artifacts, important enchantments, and decks whose engine depends on a single noncreature permanent. Card text check required for exact target classes and destination zone; prefer it over land destruction when the permanent is already producing value or when destroying lands no longer stops the opponent from casting spells. `Deglamer` is poor against creature-only aggro, spell-heavy control with few targets, and combo lists where the graveyard or hand matters more than artifacts or enchantments.

- `Gorilla Shaman` role: Bring `Gorilla Shaman` against Affinity, artifact-land mana bases, and decks where repeated artifact pressure or cheap artifact mana is visible. Card text check required for exact activated ability cost and target restrictions; use it as a mana-denial engine when the opponent exposes artifacts that can be answered before they convert them into board dominance. `Gorilla Shaman` is poor against nonartifact decks, against boards where it cannot activate profitably, and when spending red mana on it delays `Boarding Party`, `Fang Dragon`, or a needed `Breath Weapon`.

- `Relic of Progenitus` role: Bring `Relic of Progenitus` against graveyard combo, delve threats, flashback recursion, reanimation, Terror-style decks, and value engines that rely on public graveyard size. Card text check required for exact activation timing and exile pattern; use it before the opponent can convert graveyard cards into a spell, threat, or combo kill. `Relic of Progenitus` is poor against decks with no graveyard dependency, and it should not displace pressure unless the graveyard is a central resource.

- `Suplex` role: Bring `Suplex` against large creature decks, initiative threats, single high-impact attackers, and matchups where `Writhing Chrysalis` needs help stabilizing combat. Card text check required for exact target restrictions and damage/fight/bounce behavior; choose it when the legal action answers a creature that land destruction no longer prevents. `Suplex` is poor against noncreature combo, go-wide boards where one answer is not enough, and control decks with few targets.

- `Weather the Storm` role: Bring `Weather the Storm` against Burn, fast red, Rally-style burst damage, aggressive decks with many cheap spells, and matchups where gaining a full extra turn is more important than a slower top-end card. Card text check required for exact storm behavior and timing; hold it for a meaningful storm count or lethal-prevention window when legal. `Weather the Storm` is poor against slow control, land-light combo where pressure matters more, and creature boards where life gain without stabilization does not change the next attack.

- Exact plan versus fast red or Rally pressure: This plan prioritizes survival, sweepers, and lifegain while reducing slow land denial and expensive cards that do not immediately stop damage.
Side in: 4 Weather the Storm, 3 Breath Weapon, 2 Suplex
Cut: 2 Structural Distortion, 2 Avenging Hunter, 1 Fang Dragon, 3 Mwonvuli Acid-Moss, 1 Malevolent Rumble

- Exact plan versus Affinity or artifact-heavy mana: This plan adds artifact pressure while preserving enough ramp and cascade to punish stumbles.
Side in: 3 Deglamer, 2 Gorilla Shaman, 2 Suplex
Cut: 2 Structural Distortion, 2 Avenging Hunter, 1 Fang Dragon, 1 Malevolent Rumble, 1 Thermokarst

- Exact plan versus graveyard-centric Terror, reanimation, or flashback shells: This plan adds graveyard interruption and selected permanent interaction without abandoning land pressure.
Side in: 1 Relic of Progenitus, 3 Deglamer
Cut: 2 Structural Distortion, 1 Fang Dragon, 1 Malevolent Rumble

- Exact plan versus small-creature Faeries or token boards: This plan adds sweepers and creature interaction while keeping the mana engine intact.
Side in: 3 Breath Weapon, 2 Suplex
Cut: 2 Structural Distortion, 1 Fang Dragon, 2 Mwonvuli Acid-Moss

- Archetype rule versus creature swarms: Add role cards: `Breath Weapon`, `Suplex`, and sometimes `Weather the Storm` if racing matters. Reduce main-deck emphasis: slow land destruction and top-end that does not affect the next combat. Keep `Writhing Chrysalis` because it stabilizes the board and turns defensive turns into pressure.

- Archetype rule versus artifact decks: Add role cards: `Deglamer`, `Gorilla Shaman`, and `Suplex` for large artifact creatures. Reduce main-deck emphasis: slow initiative or expensive one-card threats when the opponent can snowball artifacts before turn five. Keep `Thermokarst` and `Mwonvuli Acid-Moss` when artifact lands are visible and legal targets matter.

- Archetype rule versus graveyard decks: Add role cards: `Relic of Progenitus` first, then `Deglamer` only if visible permanents or known archetype cards justify targets. Reduce main-deck emphasis: cards that are slow and noninteractive before the graveyard deck's key turn. Do not over-board away pressure, because graveyard hate without a clock lets the opponent rebuild.

- Archetype rule versus control and big mana: Add role cards only when they answer visible engines; `Deglamer` can matter against artifact or enchantment engines, while `Weather the Storm` and `Breath Weapon` are normally low priority. Reduce main-deck emphasis: dead creature removal or sweepers if brought in by mistake. Preserve `Thermokarst`, `Mwonvuli Acid-Moss`, `Structural Distortion`, and cascade threats because mana denial plus resilient pressure is the main path.

- Archetype rule versus Bogles or enchantment-heavy decks: Add role cards: `Deglamer` as the primary answer and `Weather the Storm` only when racing through large lifelink or damage pressure requires time. Reduce main-deck emphasis: single-creature interaction that cannot legally target or affect the protected threat. Card text check required before assuming `Deglamer` can answer the exact visible enchantment or permanent.

- Role-change rule after sideboarding: `Gruul Cascade` becomes a stabilizing ramp deck against aggro, a mana-prison deck against control and big mana, an artifact-punish deck against Affinity, and a clock-plus-hate deck against graveyard combo. Keep mulligans aligned with the sideboard role: sideboard cards are not enough without mana, and ramp hands are not enough if they ignore a known fast kill.

## Matchup Guidance

- Aggro: Prioritize survival into oversized blockers before pure mana denial when the opponent has multiple creatures already attacking. Keep `Arbor Elf`, `Utopia Sprawl`, and `Wild Growth` hands that reach `Writhing Chrysalis`, `Eldrazi Repurposer`, `Avenging Hunter`, `Boarding Party`, or `Annoyed Altisaur` quickly; a turn-three threat often matters more than destroying a land after the board is wide. Add role cards: `Breath Weapon`, `Suplex`, and `Weather the Storm`. Reduce main-deck emphasis: `Structural Distortion`, slower `Mwonvuli Acid-Moss` lines, and top-end that does not affect the next combat.

- Control: Attack mana first, then present cascading threats one at a time so removal and counters do not trade cleanly with the whole hand. Prioritize `Thermokarst`, `Mwonvuli Acid-Moss`, and `Structural Distortion` when the legal target is a land that constrains colors, unlocks fewer counterspell windows, or keeps the opponent off sweepers. `Boarding Party` and `Annoyed Altisaur` are preferred closers because cascade turns one resolved spell into two pieces of pressure. Add role cards: `Deglamer` only for visible artifact or enchantment engines. Reduce main-deck emphasis: `Breath Weapon`, `Weather the Storm`, and `Suplex` unless visible cards make them live.

- Combo: Use land destruction as disruption only when it changes the combo turn, not merely because a target exists. Mulligan toward acceleration plus `Thermokarst`, `Mwonvuli Acid-Moss`, `Structural Distortion`, or a fast cascade clock; slow hands that only make large creatures after the combo window are risky. Add role cards: `Relic of Progenitus` against graveyard combo, `Deglamer` against artifact or enchantment engines, and `Weather the Storm` only against storm-like damage races where life gain can legally break the kill turn. Reduce main-deck emphasis: creature combat cards that do not interrupt the visible combo resource.

- Tempo: Protect the mana engine from stumble loops by sequencing land enchantments on lands that the visible board and legal actions make least vulnerable. If the opponent is holding up interaction, prefer plays that leave a second threat or ramp line for the next turn rather than committing the only payoff into open mana. `Malevolent Rumble` can help rebuild after a counter or removal exchange if a legal selection improves future mana or threat density. Add role cards: `Suplex` for a single tempo creature that is carrying the race, and `Breath Weapon` when the visible board is many small creatures. Reduce main-deck emphasis: slow land destruction after the opponent already has enough mana to double-spell.

- Midrange: Become the bigger midrange deck by trading early life for mana advantage, then use cascade to overload one-for-one removal. `Writhing Chrysalis`, `Boarding Party`, `Annoyed Altisaur`, `Avenging Hunter`, and `Generous Ent` are the cards that let the deck turn the corner; do not spend turns on low-impact setup when the visible board demands a blocker. `Thermokarst` and `Mwonvuli Acid-Moss` are strongest before the opponent has stabilized colors; after that, favor threats or interaction that changes combat. Add role cards: `Suplex` for large creatures and `Deglamer` for value permanents. Reduce main-deck emphasis: narrow land destruction that no longer denies a spell class.

- Big mana: Pressure the mana base relentlessly and avoid switching to normal creature combat too early. `Thermokarst`, `Mwonvuli Acid-Moss`, and `Structural Distortion` should target lands that produce multiple colors, enable the opponent's next large spell, or represent a known engine from public information. `Utopia Sprawl`, `Wild Growth`, and `Arbor Elf` are essential because winning the mana fight requires acting before their payoff resolves. Add role cards: `Deglamer` only for visible artifacts or enchantments that function as mana or payoff engines. Reduce main-deck emphasis: `Breath Weapon`, `Weather the Storm`, and `Suplex` unless the opponent has transformed into creature pressure.

- Graveyard: Treat the public graveyard as a live resource and time hate before the opponent converts it into mana discount, recursion, flashback, or reanimation. Add role cards: `Relic of Progenitus` first, with `Deglamer` only when visible permanents or known archetype structure provide legal, relevant targets. Card text check required for `Relic of Progenitus` activation timing and exact exile pattern; choose the legal action that denies the next graveyard conversion while preserving pressure. Reduce main-deck emphasis: slow cards that neither clock nor disrupt. Keep `Boarding Party`, `Annoyed Altisaur`, and `Writhing Chrysalis` because hate without pressure gives graveyard decks time to rebuild.

- Artifact/enchantment: Use sideboard interaction to break the opponent's engine while keeping the ramp-cascade shell intact. Add role cards: `Deglamer` for artifacts or enchantments, `Gorilla Shaman` for artifact-heavy boards and artifact lands, and `Suplex` for large artifact creatures when legal. Card text check required for `Deglamer`, `Gorilla Shaman`, and `Suplex`; do not assume a target is legal unless Veles exposes it. Reduce main-deck emphasis: expensive threats that do not race the artifact snowball and land destruction that does not interact with artifact mana. Preserve `Thermokarst` and `Mwonvuli Acid-Moss` when artifact lands or key colored lands are visible.

- Go-wide: Stabilize the battlefield before maximizing cascade value. Add role cards: `Breath Weapon`, `Suplex`, and sometimes `Weather the Storm` when the race is damage-based. Card text check required for `Breath Weapon`; if the legal action is a sweeper effect that clears multiple attackers without destroying your essential path to stabilize, value it highly. `Writhing Chrysalis` is a key stabilizer because it can contest attacks and threaten a fast counterattack. Reduce main-deck emphasis: `Structural Distortion`, slow `Mwonvuli Acid-Moss`, and `Fang Dragon` when those plays do not change the next attack.

- Single-threat: Answer or outsize the one permanent that matters, then punish the opponent for investing in a narrow board. Add role cards: `Suplex` for a large creature, `Deglamer` for aura, equipment, artifact, or enchantment dependence, and `Weather the Storm` only when the single threat creates a lethal damage race. Card text check required before assuming any sideboard card can affect protection, ward, hexproof, or attachment structures. `Thermokarst` and `Mwonvuli Acid-Moss` are strong when they cut the opponent off recasting or protecting the threat; otherwise, prioritize `Writhing Chrysalis`, `Annoyed Altisaur`, and `Boarding Party` to dominate combat.

- Burn: Preserve life total as a core resource and do not treat early damage as free. Add role cards: `Weather the Storm` and sometimes `Breath Weapon` if the burn deck also presents small creatures. Card text check required for `Weather the Storm` storm count and timing; hold it for a legal window that blanks a lethal turn or gains enough life to create a full extra attack step, unless waiting risks losing access to the spell. Reduce main-deck emphasis: `Structural Distortion`, `Avenging Hunter`, `Fang Dragon`, and slow land-denial sequences that do not reduce damage before the next turn.

- Removal-heavy decks: Sequence threats to make one-for-one answers inefficient, and avoid exposing the only payoff when a ramp or selection action creates a second wave. `Boarding Party` and `Annoyed Altisaur` are premium because cascade can leave material even if the creature dies. `Writhing Chrysalis` and `Eldrazi Repurposer` are strong when they create multiple bodies or resources from one card; Card text check required for exact `Eldrazi Repurposer` output and timing. Add role cards: minimal sideboard changes unless removal is tied to artifacts, enchantments, graveyards, or burn. Reduce main-deck emphasis: narrow answers that do not pressure life total or mana.

## Specific Matchup Notes

- General/archetype-only note: exact opponents are absent, so revealed cards, public zones, legal actions, and matchup context from Veles override every assumption here. Treat these notes as priority-target and sideboard-role guidance, not as permission to assume hidden cards or force illegal targets.

- Red aggro or Burn: Protect life total first, then turn the corner with `Writhing Chrysalis`, `Boarding Party`, and `Annoyed Altisaur`. Add role cards: `Weather the Storm` first, plus `Breath Weapon` when the revealed board shows many small attackers. Reduce main-deck emphasis: `Structural Distortion`, slow `Mwonvuli Acid-Moss`, `Fang Dragon`, and any line that spends a turn denying mana while lethal damage is already visible. Priority targets are creatures or permanents that add immediate damage; land destruction matters only when it cuts off a known next burn sequence or double-spell turn.

- Blue tempo or Faeries-style decks: Resolve mana development before fighting over expensive payoffs. Add role cards: `Suplex` for a visible creature carrying the race, and `Breath Weapon` when the opponent commits multiple small creatures. Reduce main-deck emphasis: late `Thermokarst` effects after the opponent has enough lands and open interaction. Priority targets are blue sources before they enable counterspell turns, evasive attackers that shorten the clock, and permanents that make one-for-one removal efficient against your cascade threats.

- Affinity or artifact-heavy decks: Keep the ramp shell intact while attacking artifact engines. Add role cards: `Gorilla Shaman`, `Deglamer`, and `Suplex` when legal targets are visible. Card text check required for `Gorilla Shaman`, `Deglamer`, and `Suplex`; do not assume artifact lands, creatures, or attachments are legal targets unless Veles exposes matching actions. Reduce main-deck emphasis: expensive threats that do not stabilize before the artifact board snowballs. Priority targets are artifact lands, mana artifacts, payoff artifacts, and large artifact creatures threatening lethal.

- Big mana or Tron-style decks: Prioritize land denial before normal creature pressure if the opponent is not already presenting lethal pressure. Add role cards: `Deglamer` only for visible artifacts or enchantments that are engines or payoffs. Reduce main-deck emphasis: `Breath Weapon`, `Weather the Storm`, and `Suplex` unless the revealed plan has shifted to creatures. Priority targets are lands that unlock multiple colors, assembled engine pieces, and any public mana source that enables the next large spell.

- Graveyard or recursion decks: Use pressure plus timed hate rather than hate alone. Add role cards: `Relic of Progenitus`, and add `Deglamer` only when visible permanents matter. Card text check required for `Relic of Progenitus`; choose graveyard actions only when the legal option disrupts an imminent public conversion, recursion turn, flashback line, or graveyard-cost spell. Reduce main-deck emphasis: slow land denial that does not affect the graveyard deck’s next conversion window.

- Creature midrange or single-threat decks: Become the larger board while respecting one permanent that can dominate combat. Add role cards: `Suplex` for a large legal creature target, `Deglamer` for visible aura, equipment, artifact, or enchantment dependence, and `Weather the Storm` only if damage racing is the issue. Reduce main-deck emphasis: land destruction once the opponent can cast relevant spells through it. Priority targets are blockers that stop `Boarding Party` haste damage, evasive creatures, and threats that invalidate `Writhing Chrysalis` blocks.

## Risk Summary

- Mana risk: Hands without early green mana, `Arbor Elf`, `Utopia Sprawl`, `Wild Growth`, or a functional two-turn development path can strand `Boarding Party`, `Annoyed Altisaur`, `Fang Dragon`, and `Avenging Hunter`. Do not keep a hand just because it contains powerful top-end if visible legal sequencing cannot produce the mana in time.

- Enchanted-land risk: `Utopia Sprawl` and `Wild Growth` concentrate resources on lands, so land destruction, bounce, or tap effects can create a large tempo loss. Spread enchantments when legal and tactically comparable; concentrate only when `Arbor Elf` plus a protected `Forest` creates a decisive acceleration line.

- Matchup-role risk: The deck can lose by staying in land-denial mode after the opponent has already stabilized mana. Re-evaluate `Thermokarst`, `Mwonvuli Acid-Moss`, and `Structural Distortion` against the current board each turn; pressure and blocking may become more important than another land target.

- Draw risk: Cascade hands can flood on expensive creatures or draw ramp without payoff. Use `Malevolent Rumble` and `Generous Ent` lines conditionally to repair missing mana, threats, or land drops, but do not assume exact card text or outcomes beyond legal Veles actions.

- Over-sideboarding risk: Removing too much ramp or too many cascade threats makes the deck a weaker midrange pile. Sideboard cards should answer a visible or highly likely axis while preserving `Arbor Elf`, `Utopia Sprawl`, `Wild Growth`, `Boarding Party`, `Annoyed Altisaur`, and `Writhing Chrysalis` as the main engine.

- Graveyard risk: `Relic of Progenitus` can be low-impact if it delays pressure without stopping a public graveyard conversion. Treat graveyard hate as a timing tool, not as a substitute for ending the game.

- Sweeper/removal risk: Small support permanents and tokens can disappear to sweepers, while large threats can be answered one-for-one. Sequence `Boarding Party` and `Annoyed Altisaur` to leave material through cascade when possible, and avoid committing every stabilizer if the opponent’s visible mana and archetype suggest a sweeper.

- Closer risk: `Avenging Hunter`, `Fang Dragon`, `Boarding Party`, and `Annoyed Altisaur` can end games, but tapping out for the wrong closer can lose to a faster board or open interaction. Use a light model for finisher commitment when the opponent has visible pressure, open mana, or known answers.

- Interaction risk: Sideboard cards are narrow and target-dependent. Before choosing `Breath Weapon`, `Deglamer`, `Gorilla Shaman`, `Relic of Progenitus`, `Suplex`, or `Weather the Storm`, verify that the legal action changes the next combat, stack, graveyard, engine, or lethal window.

- Sequencing risk: Casting cascade before fixing mana, choosing the wrong land-destruction target, or spending a turn on selection while under lethal pressure can waste the deck’s advantage. Front-load mana, then deny the opponent’s decisive resource, then commit pressure when the visible board says waiting is worse.

## Test Feedback Checklist

- Deciding factor: Which visible resource decided the game: early enchanted `Forest`, `Arbor Elf` acceleration, land destruction from `Thermokarst` or `Mwonvuli Acid-Moss`, cascade pressure from `Boarding Party` or `Annoyed Altisaur`, combat dominance from `Writhing Chrysalis`, or a sideboard card?

- Mulligan quality: Did the opening hand contain a legal first two-turn plan, or was it kept because it had powerful expensive cards such as `Annoyed Altisaur`, `Boarding Party`, `Avenging Hunter`, or `Fang Dragon` without enough mana velocity?

- Mana execution: Did `Utopia Sprawl`, `Wild Growth`, and `Arbor Elf` produce a real tempo advantage, or were colors, tapped lands, missing `Forest`, or overloading one enchanted land the reason the deck stumbled?

- Velocity check: Did `Malevolent Rumble` or `Generous Ent` repair a missing land, threat, or curve gap, or did selection spend a turn that should have developed mana, destroyed a land, blocked, or committed pressure?

- Engine timing: Did the pilot move from ramp to denial to threat at the right moment, or did it keep choosing `Thermokarst`, `Mwonvuli Acid-Moss`, or `Structural Distortion` after the opponent already had enough mana?

- Removal and hate impact: Did `Breath Weapon`, `Deglamer`, `Gorilla Shaman`, `Relic of Progenitus`, or `Suplex` answer a visible pressure, engine, graveyard, artifact, enchantment, or lethal window, or did the card trade too little tempo for the turn spent? Card text check required for exact sideboard action meanings when reviewing logs.

- Sideboard discipline: Did sideboard plans preserve enough `Arbor Elf`, `Utopia Sprawl`, `Wild Growth`, `Boarding Party`, `Annoyed Altisaur`, and `Writhing Chrysalis`, or did the deck lose its core ramp-cascade identity while adding narrow answers?

- Closing ability: Did `Boarding Party` haste, `Annoyed Altisaur` pressure, `Avenging Hunter`, `Fang Dragon`, `Eldrazi Repurposer`, or `Writhing Chrysalis` actually end the game, or did the deck stabilize without converting board advantage into lethal attacks?

- Role identification: Did the pilot correctly choose between mana denial, stabilizing combat, racing, and top-end commitment each turn, especially after sideboarding against aggro, Affinity, graveyard, and big-mana opponents?

- Mistake review: Which pass, attack, block, land-destruction target, mana payment, or cascade commitment looked wrong using only the visible state and public information available at the time?

- Stranded-card review: Which cards stayed in hand too long: `Annoyed Altisaur`, `Boarding Party`, `Fang Dragon`, `Avenging Hunter`, `Structural Distortion`, `Breath Weapon`, `Weather the Storm`, `Deglamer`, `Suplex`, `Gorilla Shaman`, or `Relic of Progenitus`?

- Overperformer and underperformer review: Which exact cards generated decisive tempo, damage, blockers, mana, or disruption, and which exact cards were repeatedly low-impact in the matchup stage where they were drawn?

## First Tuning Questions

- Card quantities: Should `Structural Distortion` remain at 2 copies if logs show it is strong only against artifacts or slow mana, or should those slots become more consistent pressure, selection, or flexible interaction?

- Mana base: Do `14 Forest`, `2 Mountain`, and `1 Wooded Ridgeline` support red costs and sideboard red cards often enough without slowing turn-one `Arbor Elf`, `Utopia Sprawl`, or `Wild Growth` starts?

- Ramp density: Are 4 `Arbor Elf`, 4 `Utopia Sprawl`, and 3 `Wild Growth` enough to cast cascade threats on schedule, or do losses show too many hands with payoffs and too little early acceleration?

- Threat mix: Are 4 `Annoyed Altisaur`, 4 `Boarding Party`, 4 `Writhing Chrysalis`, 3 `Eldrazi Repurposer`, 2 `Avenging Hunter`, and 1 `Fang Dragon` the right closer package, or are some expensive threats stranded against fast decks and counterspell decks?

- Selection package: Does 3 `Malevolent Rumble` improve keep quality and recovery enough, or does it reduce the density of direct ramp, land destruction, and battlefield-impacting plays?

- Aggro plan: Are 3 `Breath Weapon` and 4 `Weather the Storm` enough against wide or burn-heavy decks, and do they enter without weakening the deck’s ability to present blockers and fast cascade pressure?

- Control and big-mana plan: Are `Thermokarst`, `Mwonvuli Acid-Moss`, and `Structural Distortion` sufficient to keep slow decks off decisive mana, or does the deck need more resilient threats or a different post-board role?

- Artifact plan: Are 3 `Deglamer`, 2 `Gorilla Shaman`, and 2 `Structural Distortion` producing enough wins against artifact-heavy boards, or are too many artifact answers target-dependent and low-impact when drawn late?

- Graveyard plan: Is 1 `Relic of Progenitus` enough when graveyard decks appear, or do logs show graveyard hate arriving too rarely or costing too much pressure?

- Role conflict: Does the deck lose more often by overcommitting to land destruction, overcommitting to expensive threats, or over-sideboarding into reactive cards that dilute the ramp-cascade core?

## Veles Tactical Policy

### Policy: Opening Hand Gate
- Priority: High
- Decision families: mulligan
- Cards: Arbor Elf, Utopia Sprawl, Wild Growth, Forest, Wooded Ridgeline, Mountain, Generous Ent, Malevolent Rumble
- Phase windows: opening hand, mulligan, London bottom
- Runtime cues: prompt:mulligan; hand contains visible lands and ramp
- Use when: Decide keep only by visible hand, known matchup role, and whether the first two turns can develop mana or repair mana.
- Avoid when: Do not keep expensive-only hands built around Annoyed Altisaur, Boarding Party, Avenging Hunter, or Fang Dragon without a castable setup path.
- Instructions: Keep hands with a green source plus Arbor Elf, Utopia Sprawl, or Wild Growth unless the hand cannot progress after turn two. Treat Generous Ent and Malevolent Rumble as repair, not replacements for an actual early mana plan.
- Pilot skill floor: Light model should compare one mulligan lower against current hand velocity.
- No-API allowed: no
- Light-model allowed: yes

### Policy: First Enabling Permanent
- Priority: Medium
- Decision families: mana, priority
- Cards: Arbor Elf, Utopia Sprawl, Wild Growth, Forest
- Phase windows: turn 1-2 main phases
- Runtime cues: action:Cast Arbor Elf; action:Cast Utopia Sprawl; action:Cast Wild Growth
- Use when: The legal action creates or enchants an early mana source before spending mana on selection or land destruction.
- Avoid when: Opponent pressure requires a legal stabilizing play, or the action would prevent casting a visible sideboard answer this turn.
- Instructions: Prioritize Arbor Elf or a land aura on Forest before Malevolent Rumble when both are legal and no immediate survival action is needed. Stack auras on a land only after checking visible land-destruction risk and available untap value.
- Pilot skill floor: Light model for sequencing if multiple setup actions are legal.
- No-API allowed: no
- Light-model allowed: yes

### Policy: Deterministic Turn-One Arbor Elf
- Priority: Low
- Decision families: mana, priority
- Cards: Arbor Elf, Forest
- Phase windows: first main phase
- Runtime cues: action:Cast Arbor Elf
- Use when: It is your first turn, you have not played another spell, you control a source that pays green, and legal action text contains Cast Arbor Elf.
- Avoid when: A forced rules prompt, known tax, or visible replacement effect changes the cost or legality.
- Instructions: Choose the Cast Arbor Elf action to establish acceleration.
- Pilot skill floor: No-API can execute only this exact legal action.
- No-API allowed: yes
- Light-model allowed: yes

### Policy: Utopia Sprawl Target And Color
- Priority: Medium
- Decision families: mana, selection
- Cards: Utopia Sprawl, Forest, Mountain, Wooded Ridgeline, Boarding Party, Breath Weapon, Gorilla Shaman
- Phase windows: main phase, aura target prompt, color choice prompt
- Runtime cues: action:target Utopia Sprawl Forest; prompt:choose color
- Use when: Utopia Sprawl is being cast and Forge asks for a legal Forest target or color.
- Avoid when: Multiple Forest targets differ by tapped status, aura load, or exposure to visible land interaction.
- Instructions: Target an untapped Forest when it is the only legal Forest target. Choose red when hand or sideboard plan needs red for Boarding Party, Breath Weapon, or Gorilla Shaman; choose green when red is already available and green top-end is constrained.
- Pilot skill floor: Light model unless exactly one target and one color is forced by the current plan.
- No-API allowed: no
- Light-model allowed: yes

### Policy: Mana Payment Preservation
- Priority: Medium
- Decision families: mana
- Cards: Forest, Mountain, Wooded Ridgeline, Arbor Elf, Utopia Sprawl, Wild Growth, Boarding Party, Annoyed Altisaur, Writhing Chrysalis
- Phase windows: all payment prompts
- Runtime cues: prompt:pay mana; action:tap
- Use when: Multiple legal mana-source payments cast the same spell or ability.
- Avoid when: Forge presents a single legal payment or a visible tax trigger must be paid immediately.
- Instructions: Preserve red if Boarding Party or red sideboard cards are visible and castable soon. Preserve the enchanted Forest plus Arbor Elf untap loop when that keeps a follow-up cascade threat or Writhing Chrysalis available.
- Pilot skill floor: Light model for multiple legal payment sets.
- No-API allowed: no
- Light-model allowed: yes

### Policy: Land Denial Commitment Gate
- Priority: High
- Decision families: priority, interaction
- Cards: Thermokarst, Mwonvuli Acid-Moss, Structural Distortion
- Phase windows: main phase with sorcery-speed legal actions
- Runtime cues: action:Cast Thermokarst; action:Cast Mwonvuli Acid-Moss; action:Cast Structural Distortion
- Use when: Decide whether spending the turn on land destruction advances the visible race more than developing a threat or blocker.
- Avoid when: Opponent already has enough visible mana, your life total is under immediate combat pressure, or a threat commitment changes the next turn cycle more.
- Instructions: Use land denial early against slow decks, color-constrained boards, bounce-land style mana, or artifact lands when legal text supports it. Stop prioritizing denial when battlefield survival or lethal pressure is the deciding visible resource.
- Pilot skill floor: Light model must evaluate target, clock, and follow-up threat.
- No-API allowed: no
- Light-model allowed: yes

### Policy: Cascade Commitment Gate
- Priority: High
- Decision families: priority, mana
- Cards: Boarding Party, Annoyed Altisaur
- Phase windows: main phase, priority with enough mana
- Runtime cues: action:Cast Boarding Party; action:Cast Annoyed Altisaur; prompt:cascade
- Use when: Decide whether tapping out for a cascade threat is better than land denial, selection, or holding a sideboard answer.
- Avoid when: Visible lethal pressure requires interaction first, or open opposing mana and known public information make waiting materially safer.
- Instructions: Commit cascade when it adds pressure and another spell before the opponent can recover. Prefer Boarding Party when haste damage matters this turn; prefer Annoyed Altisaur when size and long-game pressure matter.
- Pilot skill floor: Light model for commitment; no prediction of cascade result beyond rules-engine output.
- No-API allowed: no
- Light-model allowed: yes

### Policy: Writhing Chrysalis Stabilizer Gate
- Priority: High
- Decision families: priority, combat
- Cards: Writhing Chrysalis
- Phase windows: main phase, combat planning
- Runtime cues: action:Cast Writhing Chrysalis
- Use when: Visible combat pressure makes a large stabilizing creature more important than land denial or selection.
- Avoid when: Casting a different legal action wins this turn or prevents lethal with higher certainty from visible actions.
- Instructions: Treat Writhing Chrysalis as both pressure and a stabilizer. Do not attack with it into trades that reopen lethal unless the damage changes the race.
- Pilot skill floor: Light model for board math and attack/block implications.
- No-API allowed: no
- Light-model allowed: yes

### Policy: Selection Repair Gate
- Priority: Medium
- Decision families: selection, priority
- Cards: Malevolent Rumble, Generous Ent
- Phase windows: main phase, selection prompt, search prompt
- Runtime cues: action:Cast Malevolent Rumble; action:Activate Generous Ent; prompt:choose card
- Use when: The hand lacks the next land, ramp, threat, or answer needed for the visible turn cycle.
- Avoid when: Immediate legal pressure, land denial, or sideboard interaction is required before the opponent’s next combat or combo window.
- Instructions: Use Malevolent Rumble to repair a missing piece when tempo permits. Use Generous Ent conditionally for mana fixing or as a body only after checking exact legal action text; Card text check required for exact mode text.
- Pilot skill floor: Light model for selection and search choices.
- No-API allowed: no
- Light-model allowed: yes

### Policy: Finisher Commitment Gate
- Priority: Medium
- Decision families: priority, combat
- Cards: Avenging Hunter, Fang Dragon, Eldrazi Repurposer
- Phase windows: main phase, attack step
- Runtime cues: action:Cast Avenging Hunter; action:Cast Fang Dragon; action:Cast Eldrazi Repurposer
- Use when: The board is stable enough to convert mana into a closer or persistent pressure.
- Avoid when: A cheaper legal play prevents lethal, answers a lock piece, or keeps mana for a required tax.
- Instructions: Use Avenging Hunter when initiative-style pressure is tactically worth the risk; Card text check required for exact initiative rules in-engine. Use Fang Dragon and Eldrazi Repurposer according to legal mode/output shown by Forge.
- Pilot skill floor: Light model for commitment and combat follow-up.
- No-API allowed: no
- Light-model allowed: yes

### Policy: Combat Attack Gate
- Priority: Medium
- Decision families: combat
- Cards: Boarding Party, Annoyed Altisaur, Writhing Chrysalis, Avenging Hunter, Eldrazi Repurposer, Fang Dragon, Arbor Elf
- Phase windows: declare attackers
- Runtime cues: prompt:declare attackers
- Use when: Choose attackers from the legal combat actions using visible blockers, life totals, race, and need for defense.
- Avoid when: Attacking exposes Arbor Elf or a needed blocker while the opponent has a visible counterattack.
- Instructions: Attack with haste or large threats when damage advances lethal or forces poor blocks. Hold back creatures that are needed to prevent lethal or protect initiative-style advantage.
- Pilot skill floor: Light model for all non-forced combat.
- No-API allowed: no
- Light-model allowed: yes

### Policy: Single Forced Attack Execution
- Priority: Low
- Decision families: combat
- Cards: none
- Phase windows: declare attackers
- Runtime cues: action:attack with exactly one listed attacker
- Use when: Forge presents exactly one legal attack action and no legal no-attack action.
- Avoid when: A no-attack action or multiple attack sets are legal.
- Instructions: Select the only legal attack action.
- Pilot skill floor: No-API can execute only the sole legal attack action.
- No-API allowed: yes
- Light-model allowed: yes

### Policy: Blocking Survival Gate
- Priority: High
- Decision families: combat
- Cards: Writhing Chrysalis, Annoyed Altisaur, Eldrazi Repurposer, Avenging Hunter, Arbor Elf
- Phase windows: declare blockers, combat damage assignment
- Runtime cues: prompt:declare blockers; prompt:assign combat damage
- Use when: Opponent attackers create lethal, short-clock, or key-resource pressure.
- Avoid when: Blocking sacrifices the only path to lethal next turn and current life total survives visible damage.
- Instructions: Block to prevent lethal first, then to preserve the race, then to trade expendable creatures for attackers. Do not trade Arbor Elf unless mana acceleration no longer matters or survival requires it.
- Pilot skill floor: Light model for all blocker sets and damage assignment.
- No-API allowed: no
- Light-model allowed: yes

### Policy: Sideboard Interaction Gate
- Priority: Medium
- Decision families: interaction, priority
- Cards: Breath Weapon, Deglamer, Gorilla Shaman, Relic of Progenitus, Suplex, Weather the Storm
- Phase windows: main phase, opponent turn priority, graveyard or artifact/enchantment windows
- Runtime cues: action:Cast Breath Weapon; action:Cast Deglamer; action:Activate Gorilla Shaman; action:Activate Relic of Progenitus; action:Cast Suplex; action:Cast Weather the Storm
- Use when: A sideboard card has a visible target or timing window that changes combat, graveyard access, artifact/enchantment engine, or life-total survival.
- Avoid when: The card trades a full turn for a minor effect while ramp, land denial, or cascade would affect the next turn cycle more.
- Instructions: Check exact Forge text and targets before acting; Card text check required for sideboard cards if legal text is incomplete in the prompt.
- Pilot skill floor: Light model for all target and timing choices.
- No-API allowed: no
- Light-model allowed: yes

### Policy: Weather The Storm Survival Execution
- Priority: Medium
- Decision families: interaction
- Cards: Weather the Storm
- Phase windows: instant-speed priority, opponent end step, lethal stack window
- Runtime cues: action:Cast Weather the Storm
- Use when: Your life total is at or below visible incoming damage this turn and legal action text contains Cast Weather the Storm.
- Avoid when: A visible replacement, prevention, tax, or counter effect changes whether the action resolves or can be paid.
- Instructions: Select Cast Weather the Storm to gain life through the legal engine output; do not invent storm count or resulting life.
- Pilot skill floor: No-API may execute only this survival cast cue.
- No-API allowed: yes
- Light-model allowed: yes

### Policy: Sideboard Plan Selection
- Priority: High
- Decision families: sideboard
- Cards: Breath Weapon, Deglamer, Gorilla Shaman, Relic of Progenitus, Suplex, Weather the Storm, Structural Distortion, Thermokarst, Mwonvuli Acid-Moss, Malevolent Rumble, Fang Dragon, Avenging Hunter
- Phase windows: post-game sideboarding
- Runtime cues: prompt:sideboard; matchup label; game number
- Use when: Choose a validated balanced sideboard plan before Game 2 or Game 3.
- Avoid when: The proposed plan exceeds registered 75, changes main-deck count, or removes too much ramp-cascade identity.
- Instructions: Add Breath Weapon and Weather the Storm against fast creature or burn pressure. Add Deglamer and Gorilla Shaman against artifact/enchantment engines. Add Relic of Progenitus against graveyard dependency. Add Suplex when visible creature combat requires clean interaction; Card text check required.
- Pilot skill floor: Light model; exact executable swaps belong only to Sideboard Map.
- No-API allowed: no
- Light-model allowed: yes
