# Strategy Specifications
## Deck Name And Archetype
Xenagos, the Reveler x Manamorphose - Gruul - Hyper Ramp is an Oathbreaker Gruul ramp strategy built around command-zone access to Xenagos, the Reveler and Manamorphose, with the main plan of converting early mana acceleration into oversized battlefield threats and mana-doubling payoffs. The registered strategy tags are `ramp` and `artifact`; the deck is a rogue or hybrid build rather than a stock Oathbreaker shell because it combines planeswalker token-mana scaling, ritual bursts, artifact utility, and very large finishers in one compact singleton framework.

The repaired registration is legal for the stated Oathbreaker format: 60 main-deck cards, singleton structure outside basic lands, and 0 sideboard cards. Veles should treat this guide as executable for the repaired source while keeping post-game changes disabled.

The color and mana identity are centered on red-green acceleration, with Command Tower, Cragcrown Pathway // Timbercrown Pathway, Gruul Turf, Temple of Abandon, Wooded Foothills, Forest, Mountain, Birds of Paradise, Tinder Wall, Barbed Sextant, Manamorphose, Ruby, Daring Tracker, Radha, Heir to Keld, Priest of Urabrask, Pyretic Ritual, Seething Song, Geosurge, Vessel of Volatility, Nykthos, Shrine to Nyx, Gaea's Cradle, and Xenagos, the Reveler all pulling the deck toward explosive mana turns.the repaired Xenagos source is a legal 60-card no-sideboard Oathbreaker registration.

The primary role is proactive hyper-ramp with selective interaction, not draw-go control. Veles should value hands and lines that establish mana sources, preserve Xenagos, the Reveler loyalty when relevant, and create a decisive turn with ritual mana, creature mana, or land-based mana scaling. The interaction suite is narrow and mostly tactical: Ancient Grudge, Artifact Mutation, Ancient Grudge, Destructive Revelry, Destructive Revelry, Ground Assault, Atarka's Command, and Worldsoul's Rage should be used from legal visible targets and public context rather than held under generic control assumptions.

The artifact tag is real but secondary. Barbed Sextant, Abundant Harvest, Barbed Sextant, Ashnod's Altar, and artifact-facing interaction give the deck utility and some engine texture, but the deck should not be piloted as an artifact-combo deck unless visible legal actions and board state show an actual artifact-centered line. Ashnod's Altar and Ashnod's Altar require board-dependent evaluation; do not assume combo determinism from names alone.

Opponent information is not supplied. Matchup reads must therefore begin from visible permanents, revealed cards, known commander or oathbreaker information, public graveyards, and legal action prompts. Do not infer hidden counterspells, removal, sweepers, or graveyard hate by name unless Veles has seen them or the matchup metadata later provides them. When opponent examples are needed in later sections, they must either stay in prose or be prefixed as `opponent:` in policy card fields.

## Thesis
Xenagos, the Reveler x Manamorphose - Gruul - Hyper Ramp assembles temporary burst mana, permanent mana scaling, and one large battlefield payoff before the opponent can make normal resource exchanges matter. The deck wants an opening that produces red-green access, an early mana object or mana creature, and a bridge into Xenagos, the Reveler, Nykthos, Shrine to Nyx, Gaea's Cradle, ritual chains, or a high-impact threat. Veles should prioritize mana development first, payoff timing second, and narrow interaction only when a visible target blocks the ramp turn, threatens lethal pressure, or prevents a payoff from resolving or surviving.

The deck wins by converting excess mana into threats that dominate the board rather than by trading one-for-one forever. Colossus of Akros, Woodfall Primus, Vorinclex, Voice of Hunger, Wakeroot Elemental, Spawnsire of Ulamog, and Last March of the Ents are the main top-end pressure points; Doubling Season and Ashnod's Altar are engine payoffs when visible permanents make their text matter. Worldsoul's Rage and Reap the Past can convert a long game or excess mana into a swing, but Veles must check exact legal modes, targets, and card text before assuming a deterministic kill or recovery line.

The deck is not trying to be draw-go control, low-curve aggro, or a generic artifact combo deck. Ancient Grudge, Artifact Mutation, Ancient Grudge, Destructive Revelry, Destructive Revelry, Ground Assault, Atarka's Command, and Worldsoul's Rage are tactical tools, not a plan to exhaust every opposing resource. Barbed Sextant, Abundant Harvest, Barbed Sextant, Ashnod's Altar, and Ashnod's Altar support mana, selection, sacrifice, or engine turns, but the artifact module should not override the core hyper-ramp plan unless legal actions show a concrete line.

The main priority is to make mana productive every turn without wasting irreplaceable burst resources. Do not spend Geosurge, Seething Song, Pyretic Ritual, Infernal Plunge, Vessel of Volatility, Priest of Urabrask, Tinder Wall, Manamorphose, or Xenagos, the Reveler loyalty into a turn that leaves no meaningful permanent, threat, or protected follow-up. Use command-zone Manamorphose as fixing and velocity only when the legal action and current mana context show it improves the current sequence or unlocks a decisive cast.

## Role Package
- Threats: Colossus of Akros, Woodfall Primus, Vorinclex, Voice of Hunger, Wakeroot Elemental, Spawnsire of Ulamog, Gallia of the Endless Dance, Radha, Heir to Keld, Ruby, Daring Tracker, Agatha of the Vile Cauldron, Birds of Paradise, Tinder Wall, Priest of Urabrask, Blazing Firesinger // Seething Song, Rodeo Pyromancers, and Xenagos, the Reveler provide bodies, pressure, mana attachment, or planeswalker threat presence. Treat cheap creatures primarily as setup unless combat math, opposing life total, or a planeswalker target makes attacking visibly important.

- Payoffs: Last March of the Ents, Colossus of Akros, Woodfall Primus, Vorinclex, Voice of Hunger, Wakeroot Elemental, Spawnsire of Ulamog, Doubling Season, Worldsoul's Rage, Reap the Past, and Atarka's Command are the cards that justify spending burst mana. Commit them when the legal line creates a board swing, lethal path, mana lock, or major recovery; do not fire a payoff merely because mana is available.

- Engines: Xenagos, the Reveler, Doubling Season, Ashnod's Altar, Soulbright Flamekin, Wakeroot Elemental, Gaea's Cradle, Nykthos, Shrine to Nyx, Burgeoning, Wrenn and Six, and Agatha of the Vile Cauldron can create repeatable scaling if the board supports them. Card text check required for exact activated-cost reductions, token interactions, and copyable ability details before selecting an engine line.

- Velocity: Manamorphose, Abundant Harvest, Attune with Aether, Caravan Vigil, red-green creature selection spell, Signal the Clans, Abundant Harvest, Barbed Sextant, Big Score, Benefactor's Draught, and Reap the Past improve card flow, fixing, or access to the next mana/payoff piece. Prefer velocity before a major commitment when it can change land choice, color availability, or payoff selection without losing the decisive window.

- Interaction: Ancient Grudge, Artifact Mutation, Ancient Grudge, Destructive Revelry, Destructive Revelry, Ground Assault, Atarka's Command, and Worldsoul's Rage answer narrow visible problems or clear a path for the ramp plan. Hold interaction only when a visible permanent, stack object, combat state, or known public card makes holding mana better than advancing mana.

- Protection: The registered list has no dedicated protection package. Protect key turns through sequencing, redundant mana, selective removal, and avoiding shields-down commitments into visible bad exchanges; do not invent protection from unlisted cards or assume a protected payoff survives.

- Recursion: Reap the Past and Wrenn and Six are the main recovery tools, with Ancient Grudge also offering graveyard utility when its legal flashback action appears. Use recursion after identifying the exact public graveyard contents and legal targets; do not assume hidden or unavailable cards can be recovered.

- Mana: Command Tower, Cragcrown Pathway // Timbercrown Pathway, Gruul Turf, Temple of Abandon, Wooded Foothills, Forest, Mountain, Gaea's Cradle, Nykthos, Shrine to Nyx, Birds of Paradise, Tinder Wall, Barbed Sextant, Manamorphose, Ruby, Daring Tracker, Radha, Heir to Keld, Priest of Urabrask, Pyretic Ritual, Seething Song, Geosurge, Infernal Plunge, Vessel of Volatility, Soulbright Flamekin, Burgeoning, and Xenagos, the Reveler define the deck. Count colors, devotion, creature count, land drops, sacrifice costs, and floating mana before choosing any expensive line.

- Sideboard modules: No sideboard cards are registered. Veles should never generate a sideboard action for this list unless the deck registration changes.

## Primary Win Conditions
- Big-permanent ramp is the primary win path: assemble red-green mana, a creature count or devotion base, and burst resources from Xenagos, the Reveler, Gaea's Cradle, Nykthos, Shrine to Nyx, Seething Song, Pyretic Ritual, Geosurge, Vessel of Volatility, Tinder Wall, Priest of Urabrask, or Manamorphose, then resolve Colossus of Akros, Woodfall Primus, Vorinclex, Voice of Hunger, Wakeroot Elemental, or Spawnsire of Ulamog. Prioritize this line when a payoff is in hand, colors are stable, and spending rituals produces a permanent that can dominate the next turn cycle; avoid it when visible interaction or combat pressure makes a single shields-down threat too fragile.

- Xenagos scaling is the cleanest engine path: use early bodies such as Birds of Paradise, Ruby, Daring Tracker, Gallia of the Endless Dance, Radha, Heir to Keld, Tinder Wall, Priest of Urabrask, Rodeo Pyromancers, or tokens from Xenagos, the Reveler to increase creature count, then convert Xenagos, the Reveler mana into a large cast or multiple spells. Prioritize this line when the battlefield already contains creatures and the opponent is not about to remove Xenagos, the Reveler or kill through the setup turn.

- Doubling Season into planeswalker pressure is a high-upside engine path: resolve Doubling Season only when it immediately improves Xenagos, the Reveler, token production, counters, or another visible permanent. Card text check required for exact loyalty and counter interactions; choose this line when it creates a decisive follow-up, not when it merely spends a turn without affecting survival.

- Last March of the Ents is the creature-conversion payoff: build enough mana and hand density that resolving it can put a decisive creature package onto the battlefield. Card text check required for exact draw and creature-putting conditions; prioritize it when hand contains major creatures and the opponent cannot easily punish a sorcery-speed commitment.

- Worldsoul's Rage and Reap the Past are excess-mana closers or recovery swings: use them after counting legal targets, graveyard contents, and available X mana. Card text check required for exact modes and targeting; prioritize these when a board payoff is absent but mana is abundant.

## Secondary Win Conditions
- Combat pressure is the default backup when top-end is delayed: attack with Gallia of the Endless Dance, Radha, Heir to Keld, Ruby, Daring Tracker, Agatha of the Vile Cauldron, Woodfall Primus, Vorinclex, Voice of Hunger, Wakeroot Elemental, tokens, or animated lands only when the visible blocks and crack-back leave the ramp plan intact. Do not trade away Birds of Paradise, Tinder Wall, or Priest of Urabrask before checking whether their mana or creature count is needed.

- Wakeroot Elemental gives a creature-land fallback line when lands and mana are plentiful. Card text check required for exact activation and land animation rules; use this line when ordinary creature threats are removed and the legal action shows a land can become relevant pressure without exposing essential mana to a bad combat exchange.

- Atarka's Command, Destructive Revelry, Artifact Mutation, Ancient Grudge, Ancient Grudge, Destructive Revelry, Ground Assault, and Worldsoul's Rage can support chip-damage, blocker-clear, or tempo finishes, but they are not a burn deck by themselves. Spend them proactively only when a visible target blocks lethal pressure, protects an opposing engine, or creates a near-term win.

- Reap the Past, Wrenn and Six, Ancient Grudge flashback, Abundant Harvest, Barbed Sextant, Big Score, Benefactor's Draught, Signal the Clans, Abundant Harvest, Attune with Aether, Caravan Vigil, and red-green creature selection spell form the long-game value backup. Use them to rebuild cards, lands, or selection after the first payoff is answered; do not let value actions consume the mana window needed for a visible winning cast.

- Vorinclex, Voice of Hunger can become a soft lock when it resolves against mana-dependent opponents. Card text check required for exact mana-denial behavior; protect this line by choosing it when the opponent is low on board and needs lands to answer the threat.

## Emergency Lines
- When behind on life, stabilize before ramping harder: cast Ground Assault, Artifact Mutation, Destructive Revelry, Ancient Grudge, Ancient Grudge, Destructive Revelry, or Worldsoul's Rage only against legal visible threats that change the clock, then use remaining mana to deploy blockers or a payoff.

- When behind on board, preserve creatures that generate mana unless blocking prevents lethal or a decisive attack. A small mana creature often represents Colossus of Akros, Woodfall Primus, Vorinclex, Voice of Hunger, Last March of the Ents, or Spawnsire of Ulamog next turn; trade it only when the rules-engine combat output shows survival requires it.

- When behind on cards, route toward Abundant Harvest, Barbed Sextant, Big Score, Benefactor's Draught, Reap the Past, Wrenn and Six, Abundant Harvest, Signal the Clans, or command-zone Manamorphose before spending the last ritual. Do not cast Seething Song, Pyretic Ritual, Geosurge, Infernal Plunge, or Vessel of Volatility into an empty payoff state.

- When behind on mana, prioritize land access and fixing from Abundant Harvest, Attune with Aether, Caravan Vigil, Wooded Foothills, Barbed Sextant, Manamorphose, Command Tower, Cragcrown Pathway // Timbercrown Pathway, Temple of Abandon, Gruul Turf, Forest, and Mountain. Delay color-intensive or X-spell lines until the legal mana payment is explicit.

- When engines are removed, switch to direct threat casting and recursion instead of rebuilding every piece. Use Reap the Past or Wrenn and Six only for visible public resources that restore mana, payoff access, or survival.

- When primary win conditions are gone, win through Wakeroot Elemental land pressure, Xenagos, the Reveler tokens, medium creature attacks, and selective interaction. Keep choosing legal actions that improve battlefield damage or mana quality; do not assume hidden outs or unavailable sideboard cards exist.

## Resource Model
- Life is a spendable buffer only when it buys a decisive mana or board turn. Take damage instead of chump-blocking with Birds of Paradise, Tinder Wall, Priest of Urabrask, Ruby, Daring Tracker, Radha, Heir to Keld, or Xenagos, the Reveler tokens when those bodies enable Gaea's Cradle, Nykthos, Shrine to Nyx, Xenagos, the Reveler mana, Last March of the Ents, or a top-end cast; block with them only when visible combat math threatens lethal or makes the next payoff turn impossible.

- Hand is the deck's fuel cache, not just card count. Keep at least one payoff, selection spell, or reload path alongside burst mana; avoid spending Seething Song, Pyretic Ritual, Geosurge, Infernal Plunge, Vessel of Volatility, or Manamorphose when the remaining hand cannot convert the mana into Xenagos, the Reveler, Doubling Season, Colossus of Akros, Woodfall Primus, Vorinclex, Voice of Hunger, Wakeroot Elemental, Spawnsire of Ulamog, Last March of the Ents, Worldsoul's Rage, or Reap the Past.

- Mana is the primary resource and must be counted in permanent, burst, and conditional layers. Permanent mana comes from lands and creatures; burst mana comes from rituals and sacrifice effects; conditional mana comes from Gaea's Cradle, Nykthos, Shrine to Nyx, Xenagos, the Reveler, Soulbright Flamekin, Agatha of the Vile Cauldron, and Wakeroot Elemental when legal actions expose usable abilities. Card text check required for exact activated-ability discounts, devotion, and land-animation payments.

- Board material converts into mana, pressure, and sacrifice fodder before it converts into damage. Preserve creatures for Gaea's Cradle, Xenagos, the Reveler, Last March of the Ents, Benefactor's Draught, and Ashnod's Altar lines unless an attack or block clearly advances lethal, protects Xenagos, the Reveler, or prevents death.

- Graveyard resources matter through Ancient Grudge, Wrenn and Six, Reap the Past, and any visible recursion from rules-engine output. Treat fetch lands, rituals, sacrificed creatures, and answered payoffs as future material only when a legal action actually references them; do not assume a graveyard card is recoverable without a listed action.

- Exile is mostly a tracking zone for resolved effects and unavailable cards. If a card is exiled by an opponent effect, stop planning around it unless the visible state or legal action list explicitly offers play permission or recovery.

- Lands are both mana and strategic objects. Forest and Mountain support basic color stability; Command Tower and Cragcrown Pathway // Timbercrown Pathway fix both colors; Temple of Abandon improves selection at tempo cost; Gruul Turf recovers a land drop but risks tempo; Wooded Foothills fixes and stocks the graveyard; Gaea's Cradle and Nykthos, Shrine to Nyx are payoff lands that require board context before being valued as full sources.

- Sacrifice fodder must be assigned before committing Infernal Plunge, Ashnod's Altar, or any visible sacrifice action. Prefer expendable tokens or creatures whose mana has already been used; avoid sacrificing Birds of Paradise, Tinder Wall, Priest of Urabrask, or a devotion creature if doing so reduces the exact mana needed for the payoff.

- Tempo is gained by turning one turn of burst into a permanent that dominates multiple turns. Spend tempo on Xenagos, the Reveler, Doubling Season, Vorinclex, Voice of Hunger, Woodfall Primus, or Last March of the Ents when the opponent's visible board cannot punish the shields-down; spend tempo defensively on Ground Assault, Ancient Grudge, Artifact Mutation, Destructive Revelry, Ancient Grudge, Destructive Revelry, or Atarka's Command only when the target changes the next combat or engine race.

- Information comes from visible zones, legal actions, public graveyards, known revealed cards, and selection outcomes. Use Abundant Harvest, Attune with Aether, Caravan Vigil, Barbed Sextant, Abundant Harvest, Barbed Sextant, Signal the Clans, red-green creature selection spell, and Manamorphose to reduce uncertainty before committing rituals when the selection can change land choice, color choice, target choice, or payoff timing.

- Sideboard bullets do not exist for this registration. Because the sideboard is empty, never plan around post-board cards, and never treat matchup-specific answers outside the registered main deck as available.

## Mana Guide
- Green access is the highest early-color priority because it enables Birds of Paradise, Abundant Harvest, Attune with Aether, Caravan Vigil, Burgeoning, Tinder Wall, red-green creature selection spell, Wrenn and Six, Signal the Clans, and many top-end creature lines. Keep hands without green only when red mana plus legal selection or Manamorphose clearly reaches green before the hand stalls.

- Red access is the burst-color priority because it enables Pyretic Ritual, Seething Song, Geosurge, Infernal Plunge, Ancient Grudge, Destructive Revelry, Ground Assault, Atarka's Command, Destructive Revelry, and many Xenagos, the Reveler turns. Keep red-light hands only when Command Tower, Cragcrown Pathway // Timbercrown Pathway, Barbed Sextant, Manamorphose, Birds of Paradise, or search effects can produce red on time.

- Opening hands need two functional mana sources or one land plus a credible one-mana stabilizer. A hand with Forest plus Birds of Paradise, Abundant Harvest, Attune with Aether, or Caravan Vigil can be keepable; a hand with only Mountain and expensive green cards is usually a mulligan unless legal pregame context makes the risk acceptable.

- Play tapped lands early when the hand does not need immediate ritual mana. Temple of Abandon is best before a turn where the scry can decide land versus payoff; Gruul Turf is best after another land is available to replay or when the bounce protects a utility land from low immediate pressure.

- Delay the land drop before Abundant Harvest, Barbed Sextant, Abundant Harvest, Attune with Aether, Caravan Vigil, Barbed Sextant, Manamorphose, or Wooded Foothills only when the choice can change which land should be played. Play the land first when casting rituals, paying for Xenagos, the Reveler, using a legal action that requires exact mana, or avoiding a missed land drop after selection is unlikely to matter.

- Count Gaea's Cradle and Nykthos, Shrine to Nyx after creature count and devotion are known, not as unconditional lands. Sequence cheap permanents before activating them when that increases output and still leaves enough untapped mana to cast the intended spell.

- Use Manamorphose as fixing when color is the bottleneck and as storm-like velocity only after the payoff turn is chosen. Do not cash it in merely because it is legal if the unknown draw or color choice should be informed by the next land, target, or ritual decision.

- Preserve exact payment flexibility on large turns by floating colors before generic mana only when the rules engine exposes safe payment choices. When legal actions ask for color selection, choose the colors that satisfy known follow-up cards in hand before speculative future draws.

## Mulligan Guide
- Strong keep: keep Forest plus Birds of Paradise plus any two of Abundant Harvest, Attune with Aether, Caravan Vigil, Tinder Wall, Ruby, Daring Tracker, Pyretic Ritual, Seething Song, or Xenagos, the Reveler because the hand has color access, early board material, and a realistic burst turn.

- Strong keep: keep Command Tower or Cragcrown Pathway // Timbercrown Pathway plus a second land, Manamorphose, and a payoff such as Doubling Season, Woodfall Primus, Vorinclex, Voice of Hunger, Last March of the Ents, or Spawnsire of Ulamog when at least one early play is present.

- Medium keep: keep Temple of Abandon or Gruul Turf hands with two other mana sources and selection from Barbed Sextant, Abundant Harvest, Barbed Sextant, Abundant Harvest, or Attune with Aether when the first two turns can still make mana or find land.

- Risky keep: keep one-land Forest only with Birds of Paradise, Abundant Harvest, Attune with Aether, or Caravan Vigil plus a castable follow-up; ship one-land Forest with only rituals and seven-plus-mana payoffs because red burst cannot start without the second source.

- Risky keep: keep Mountain plus Barbed Sextant or Manamorphose only when the rest of the hand has cheap green follow-up; ship Mountain-only hands with Burgeoning, Wrenn and Six, Signal the Clans, red-green creature selection spell, or Last March of the Ents stranded.

- Automatic ship: mulligan hands with no land, hands with only Gaea's Cradle or Nykthos, Shrine to Nyx as mana, hands with only top-end permanents, and hands that cannot produce green or red by turn two through visible cards.

- Matchup-dependent keep: keep Ancient Grudge, Artifact Mutation, Destructive Revelry, or Ancient Grudge in the opener only when opponent identity or revealed companion/deck context indicates artifacts or enchantments are central; otherwise treat multiple reactive cards as a slow hand.

- Play/draw adjustment: on the play, prefer Birds of Paradise, Tinder Wall, Burgeoning, or one-mana selection over tapland-heavy keeps; on the draw, accept slower Temple of Abandon, Gruul Turf, Abundant Harvest, or Barbed Sextant hands if they have two lands and a payoff.

- Trap hand: do not keep Geosurge, Seething Song, Pyretic Ritual, Infernal Plunge, Colossus of Akros, and Spawnsire of Ulamog without a creature to sacrifice, stable red, and enough follow-up mana; burst cards without setup become mulligans in practice.

## Turn Arc
- Turn 1: lead with green access and a permanent mana play whenever legal. Preferred starts are Forest into Birds of Paradise, Forest into Abundant Harvest naming the missing resource, Forest into Attune with Aether or Caravan Vigil, or Command Tower into Burgeoning when extra lands are already in hand.

- Turn 1 deviation: play Temple of Abandon early when no untapped one-mana play exists and the scry can decide land density. Use Wooded Foothills before selection only if fixing is required; otherwise keep land-drop timing flexible until Abundant Harvest, Barbed Sextant, Abundant Harvest, Barbed Sextant, or Manamorphose choices are clearer.

- Turn 2: develop the second mana layer before spending burst. Preferred plays are Ruby, Daring Tracker, Radha, Heir to Keld, Gallia of the Endless Dance, Wrenn and Six, Tinder Wall plus follow-up, Barbed Sextant fixing, or Signal the Clans when the hand needs a creature package; Card text check required for exact Signal the Clans candidate handling.

- Turn 2 deviation: use Ground Assault, Destructive Revelry, Ancient Grudge, Ancient Grudge, Destructive Revelry, or Artifact Mutation only when the target changes the opponent's next turn or protects a key ramp plan. Do not fire interaction into low-impact permanents while the deck still lacks a payoff route.

- Turn 3: aim to convert setup into Xenagos, the Reveler, Doubling Season, Big Score, Vessel of Volatility, Soulbright Flamekin, or a ritual chain that lands a durable threat. Count creature permanents for Gaea's Cradle, devotion for Nykthos, Shrine to Nyx, and sacrifice fodder for Infernal Plunge before choosing payments.

- Turn 3 deviation: cast Manamorphose before committing rituals only when color choice or the drawn card can change the line. If the legal action list offers Xenagos, the Reveler and Manamorphose sequencing, prioritize the line that leaves colors for the known follow-up rather than maximizing unused generic mana.

- Turns 4-5: commit the first dominating payoff when visible pressure and open interaction allow it. Preferred payoffs are Vorinclex, Voice of Hunger, Woodfall Primus, Last March of the Ents, Wakeroot Elemental, Colossus of Akros, Spawnsire of Ulamog, or Reap the Past when the graveyard has meaningful targets and the rules engine exposes a legal cast.

- Turns 4-5 deviation: spend Benefactor's Draught, Atarka's Command, Benefactor's Draught, or interaction defensively when life total, combat math, or a visible engine threat would make a shields-down lose the game. Use Ashnod's Altar and Ashnod's Altar only after confirming the visible ability or sacrifice line advances mana, protection, or lethal.

- Late game: loop between mana multiplication, selection, and must-answer threats. Use Wrenn and Six, Reap the Past, Worldsoul's Rage, Woodfall Primus, Vorinclex, Voice of Hunger, Wakeroot Elemental, and Spawnsire of Ulamog as the endurance plan, but choose targets and X values only from legal actions and visible board state.

## Card Roles
- Xenagos, the Reveler is the deck's central mana engine and threat bridge. Cast or protect Xenagos when the battlefield already has creatures or when a 2/2 Satyr token will stabilize the next turn; avoid spending a turn on Xenagos into obvious lethal pressure unless the legal action list also preserves life or blockers.

- Manamorphose is fixing first and velocity second. Use it when the current line needs exact red-green colors, when the draw can change a ritual/payoff sequence, or when command-zone access makes it the cleanest bridge into Xenagos, the Reveler; do not cycle it before land and target decisions if the color choice is still uncertain.

- Birds of Paradise, Tinder Wall, Ruby, Daring Tracker, Radha, Heir to Keld, Priest of Urabrask, Vessel of Volatility, Pyretic Ritual, Seething Song, Geosurge, Infernal Plunge, and Blazing Firesinger // Seething Song are burst or setup mana. Sequence permanent mana before one-shot mana unless a payoff is already legal this turn; treat Infernal Plunge as a commitment card that needs expendable creature material, not a generic accelerator.

- Burgeoning, Attune with Aether, Caravan Vigil, Abundant Harvest, Barbed Sextant, Abundant Harvest, and Big Score are smoothing tools. Use them to convert sketchy hands into lands, colors, and action; avoid spending Big Score before checking whether the discard cost removes the only payoff, interaction spell, or land needed for a following turn.

- Gaea's Cradle and Nykthos, Shrine to Nyx are explosive but conditional mana lands. Count visible creatures for Gaea's Cradle and visible devotion for Nykthos, Shrine to Nyx before choosing a line; do not evaluate hands with only these lands as functional mana without supporting lands or creatures.

- Command Tower, Cragcrown Pathway // Timbercrown Pathway, Temple of Abandon, Gruul Turf, Wooded Foothills, Mountain, and Forest are the baseline color plan. Lead on untapped green when Birds of Paradise, Abundant Harvest, Attune with Aether, Caravan Vigil, or Burgeoning is available; play Gruul Turf when the bounce does not delay a needed burst turn.

- Doubling Season is a high-impact engine amplifier. Commit it when the next visible sequence can exploit Xenagos, the Reveler, counters, tokens, or large permanents; do not cast it as a do-nothing shield when the opponent has lethal pressure or when interaction must be held.

- Ashnod's Altar is a sacrifice-to-mana engine, not free value. Use it when visible creatures can convert into a payoff, protect material from exile/control effects, or enable a decisive burst; avoid sacrificing mana creatures that are needed for Gaea's Cradle, Xenagos, the Reveler, or blockers unless the follow-up is already legal.

- Ashnod's Altar supports activated-ability scaling. Card text check required for each equipped or attached ability in runtime; only commit mana when the visible target ability is worth copying and the rules engine exposes legal equip or activation lines.

- Soulbright Flamekin and Agatha of the Vile Cauldron are activated-ability support pieces. Card text check required for exact cost reduction or mana conversion at runtime; prioritize them when Wakeroot Elemental, Spawnsire of Ulamog, Colossus of Akros, or other visible activated abilities are part of the current hand.

- Wakeroot Elemental is a mana-sink and land-based pressure card. Cast it when lands can safely become threats or when extra mana must convert into board presence; avoid exposing critical lands to combat or removal if the deck still needs them for a larger payoff.

- Colossus of Akros is the largest board-stalling and finishing body. Treat it as a payoff for ritual and Xenagos mana, then decide monstrosity or attack lines only from legal action text, visible blockers, and available mana; do not assume it wins without checking evasion, tap status, and removal windows.

- Vorinclex, Voice of Hunger is the premium shields-down threat. Cast it when the opponent is unlikely to punish the shields-down turn or when waiting gives them a faster clock; prioritize it in grindy matchups because it constrains opposing mana while multiplying future payoff turns.

- Woodfall Primus is the catch-up and disruption payoff. Aim it at the most important visible noncreature permanent when legal, especially mana engines, lock pieces, or planeswalkers; do not fire it at a low-impact target merely to spend mana if a more decisive turn is likely soon.

- Spawnsire of Ulamog is a late-game mana sink and board producer. Card text check required for any outside-the-game functionality in this Oathbreaker context; use visible token or activated lines only when the action text is legal and advances lethal, defense, or mana conversion.

- Last March of the Ents is the creature-heavy payoff draw/deploy spell. Card text check required for exact restriction and effect timing; cast it when hand and board contain enough creatures or high-power material to justify tapping low, not when it merely replaces itself under pressure.

- Reap the Past is the graveyard recovery payoff. Use it after rituals, sacrificed permanents, fetches, or traded interaction have stocked meaningful cards; choose X from visible mana and recovery needs rather than maximizing X at the cost of leaving no interaction or follow-up.

- Worldsoul's Rage is a scalable mana sink and land recursion/damage-style payoff. Card text check required for exact modes and targets; prefer it when the graveyard has lands, the board needs a swing, or excess mana must become immediate material.

- Wrenn and Six is land recursion, incremental damage, and long-game texture. Pair it with Wooded Foothills, Gruul Turf bounce decisions, and land-drop pressure; protect it only when repeated land access or a visible small-creature target matters more than advancing ramp.

- Ground Assault, Destructive Revelry, Ancient Grudge, Ancient Grudge, Artifact Mutation, Destructive Revelry, and Atarka's Command are interaction with narrow or modal jobs. Use Ground Assault for creatures once land count makes it reliable; use artifact and enchantment answers only on visible permanents that block the ramp plan, threaten lethal, or shut off activated/mana lines.

- Artifact Mutation is removal plus board material when the opponent exposes an artifact. Prioritize targets that also create enough creatures to improve Xenagos, the Reveler and Gaea's Cradle turns; do not hold it forever against non-artifact decks if no legal target exists.

- Ancient Grudge is best when flashback creates a two-for-one against artifact decks. Spend the first half early on mana rocks, equipment, or engines that accelerate the opponent past you; preserve the graveyard half when a more dangerous artifact is likely and the current target is low impact.

- Destructive Revelry is flexible hate with damage pressure. Fire it at enchantments or artifacts that stop mana, combat, graveyard recovery, or activated abilities; in race scenarios, include the damage only after the permanent's strategic value is confirmed by visible state.

- Ancient Grudge and Destructive Revelry are narrow safety valves. Card text check required for exact legal targets in the current rules engine; keep them only when opponent colors or revealed permanents make the target class live.

- Ground Assault is a small-creature sweeper role player. Use it against token boards, mana creatures, or one-toughness pressure that would otherwise invalidate Xenagos or life total; avoid casting it into your own important one-toughness creatures unless the exchange clearly protects a payoff turn.

- Atarka's Command is a modal tempo card. Card text check required for exact mode pairing; use it for lethal pressure, anti-life-gain, land acceleration, or team damage only when the selected modes are visible legal actions and match the board.

- Signal the Clans and red-green creature selection spell are creature selection or deployment tools. Card text check required for exact hidden-library and randomness handling; use them to find or accelerate the creature role the hand lacks, such as early mana, a payoff creature, or a utility threat.

- Gallia of the Endless Dance and Rodeo Pyromancers are pressure-plus-utility creatures. Card text check required for exact trigger or mana role; cast them when a creature count matters for Xenagos, the Reveler, Gaea's Cradle, Ashnod's Altar, or combat pressure, not as isolated attackers into bad blocks.

- Benefactor's Draught and Benefactor's Draught are situational swing cards. Card text check required for exact timing and effect; hold them until combat, mana generation, or life-pressure math makes the effect materially change survival or a payoff turn.

## Interaction Priorities

- Remove mana denial and lock pieces first when they prevent the ramp turn. Use Destructive Revelry, Ancient Grudge, Artifact Mutation, Ancient Grudge, Destructive Revelry, or Woodfall Primus on visible artifacts, enchantments, lands, or other noncreature permanents only when the legal action text supports the target and the permanent blocks mana production, command-zone access, activated abilities, combat, or a near-term payoff.

- Kill creature pressure before slow setup when the opponent can race a shields-down payoff. Use Ground Assault on the creature that most threatens life total, Xenagos, the Reveler, Wrenn and Six, or a required mana creature; use Ground Assault when multiple one-toughness creatures, tokens, or mana creatures would otherwise invalidate a payoff turn.

- Preserve narrow answers for live target classes instead of spending them on low-impact objects. Ancient Grudge should favor artifacts that accelerate, equip, combo, or shut off your plan; Artifact Mutation should favor artifacts where both destruction and the resulting creature material matter for Xenagos, the Reveler, Gaea's Cradle, Ashnod's Altar, or combat; Destructive Revelry should answer the most disruptive artifact or enchantment before treating its damage as race text.

- Treat Ancient Grudge and Destructive Revelry as conditional interaction, not generic permission. Card text check required for exact targets; if the rules engine exposes a legal counter, destroy, or target action, spend it on a decisive spell or permanent that would stop the ramp chain, kill a key payoff, or create an unrecoverable tempo gap.

- Do not invent discard, exile, or bounce plans because this list has no reliable registered discard, exile, or bounce package. Choose such actions only when Forge exposes them from a legal visible source, and prefer the target that most directly protects mana, stops lethal, or clears a payoff lane.

- Bait opposing interaction with replaceable ramp before committing fragile payoffs. Barbed Sextant, Abundant Harvest, Abundant Harvest, Attune with Aether, Caravan Vigil, Birds of Paradise, Tinder Wall, Priest of Urabrask, Pyretic Ritual, and Seething Song can bait removal or permission; avoid leading with Vorinclex, Voice of Hunger, Doubling Season, Last March of the Ents, or Colossus of Akros when a cheaper legal spell can test the shields first.

- Ignore low-impact permanents when racing toward a decisive mana turn. Do not spend Ancient Grudge, Destructive Revelry, Artifact Mutation, Ground Assault, or Woodfall Primus on decorative blockers, small non-mana artifacts, or minor enchantments unless they create lethal pressure, block a required attack, disable activated abilities, or threaten a rules-engine-visible combo.

- Shift interaction priority by archetype from mana denial to survival. Against fast creature decks, prioritize Ground Assault, blockers, and life-preserving Atarka's Command or Benefactor's Draught modes if legal; against artifact or enchantment engines, prioritize Ancient Grudge, Artifact Mutation, Destructive Revelry, Ancient Grudge, and Woodfall Primus; against blue or reactive decks, prioritize bait sequencing and only tap low for Vorinclex, Voice of Hunger or Doubling Season when waiting is worse.

## Combat And Trading Rules

- Attack only when combat advances mana, planeswalker pressure, lethal, or a protected clock. Gallia of the Endless Dance, Ruby, Daring Tracker, Radha, Heir to Keld, Rodeo Pyromancers, tokens from Artifact Mutation, and animated lands from Wakeroot Elemental should not be sent into trades that reduce Gaea's Cradle, Ashnod's Altar, Xenagos, the Reveler, or Last March of the Ents output unless the damage or planeswalker pressure is worth the material loss.

- Block to protect the next payoff turn, not every point of life. Trade Birds of Paradise, Tinder Wall, Priest of Urabrask, or small utility creatures only when life total, planeswalker loyalty, or lethal math requires it; preserve them when they are needed for Gaea's Cradle, Xenagos, the Reveler mana, Ashnod's Altar, Benefactor's Draught, or a same-turn ramp chain.

- Preserve engine creatures over medium attacks. Agatha of the Vile Cauldron, Soulbright Flamekin, Wakeroot Elemental, Ruby, Daring Tracker, and Radha, Heir to Keld should survive when their visible activated, mana, or combat text is part of the current plan; attack with them only when blocks are favorable, the opponent is tapped down, or the rules engine exposes a decisive combat line.

- Use large payoffs as shields before finishers when behind. Colossus of Akros, Woodfall Primus, Vorinclex, Voice of Hunger, Spawnsire of Ulamog, and Wakeroot Elemental can stabilize the board; decline attacks that expose them to obvious double blocks or combat tricks unless lethal, planeswalker removal, or post-combat mana conversion is visible.

- Treat life thresholds as commitment gates. Above a comfortable life total, prefer preserving creatures and mana for explosive turns; under a short clock, block with expendable ramp, use Ground Assault or Ground Assault earlier, and value Benefactor's Draught or Benefactor's Draught only when the legal timing changes survival or the next payoff.

- Use Atarka's Command as a combat or race tool only when modes are legal and visible. Card text check required for exact mode pairing; choose damage, pump, anti-life-gain, or land-related modes according to current combat math rather than assuming the card is always a finisher.

- Avoid sacrificing combat material without checking downstream mana. Infernal Plunge, Ashnod's Altar, and Tinder Wall can convert creatures into burst mana, but do not sacrifice the only blocker or the creature count needed for Xenagos, the Reveler, Gaea's Cradle, Benefactor's Draught, or Last March of the Ents unless the resulting spell sequence is legal and materially stronger.

- Change combat posture by opponent role. Against aggro, trade early and protect life until a large stabilizer lands; against control, pressure planeswalkers and life total with small creatures while holding premium payoffs; against artifact engines, keep tokens and bodies for pressure after Artifact Mutation or Ancient Grudge breaks the key permanent; against bigger ramp, attack their setup window before they outscale your payoffs.

## Selection And Tutor Rules

- Choose land with Abundant Harvest when the hand cannot make the next land drop, cannot cast Xenagos, the Reveler, or needs a specific color before a ritual chain. Choose nonland only after the current land drop is secured or when a payoff, interaction spell, or creature body is required more than raw mana.

- Use Attune with Aether and Caravan Vigil before speculative draw/filter effects when color stability is the bottleneck. Favor the basic land that unlocks the most legal hand actions this turn and next turn; do not fetch Mountain or Forest by habit if Command Tower, Gruul Turf, Cragcrown Pathway // Timbercrown Pathway, or Temple of Abandon already covers that color.

- Delay Abundant Harvest until the hand has two cards that can be safely put back or until a shuffle/search effect can clear weak top cards. When using Abundant Harvest before Wooded Foothills, Attune with Aether, Caravan Vigil, Signal the Clans, or Abundant Harvest, place cards on top only if the follow-up can legally convert them into better draws or preserve a key card from discard-like pressure.

- Use Barbed Sextant scry to protect mana first, then payoff access. Bottom expensive cards such as Colossus of Akros, Spawnsire of Ulamog, Last March of the Ents, Vorinclex, Voice of Hunger, or Woodfall Primus when early mana is missing; keep them when the hand already has burst mana, Xenagos, the Reveler, Gaea's Cradle, Nykthos, Shrine to Nyx, or a realistic ritual chain.

- Build Signal the Clans piles from cards that all serve the same visible need because the final card may not be fully controllable. For mana setup, prefer creatures such as Birds of Paradise, Ruby, Daring Tracker, Radha, Heir to Keld, Priest of Urabrask, Tinder Wall, or Soulbright Flamekin; for payoff pressure, prefer Wakeroot Elemental, Woodfall Primus, Vorinclex, Voice of Hunger, or Spawnsire of Ulamog; for sacrifice or engine turns, consider Agatha of the Vile Cauldron, Rodeo Pyromancers, or creatures that pair with Ashnod's Altar. Card text check required for exact Signal the Clans selection and randomization behavior in the active engine.

- Treat the red-green creature selection action as pseudo-selection until Forge exposes exact candidates. Card text check required; if the legal choice list shows small creatures, choose the candidate that fixes mana, adds immediate pressure, or enables Xenagos, the Reveler, Gaea's Cradle, Nykthos, Shrine to Nyx, Ashnod's Altar, or Benefactor's Draught this turn cycle.

- Use Manamorphose as color fixing plus velocity, not as an automatic first spell. Cast it before committing Geosurge, Seething Song, Pyretic Ritual, Infernal Plunge, Vessel of Volatility, or Xenagos, the Reveler when the drawn card or chosen colors can change the turn; hold it when storm-like sequencing is irrelevant and the current hand already spends mana cleanly.

- Use Reap the Past only after graveyard contents and available mana make the return range meaningful. Card text check required for exact random/targeting behavior; do not spend a large mana turn on it if the graveyard mostly contains spent cantrips, narrow interaction, or lands and a visible payoff can be cast instead.

## Priority And Stack Rules

- Pass priority quickly when the stack is empty, the opponent has no visible lethal setup, and all useful plays are sorcery-speed. This deck gains more from preserving decision budget for commitment turns than from overthinking harmless upkeep, draw-step, and end-step windows.

- Respond with Ancient Grudge, Destructive Revelry, Artifact Mutation, Ancient Grudge or Destructive Revelry only when the visible spell or permanent would disrupt mana, stop Xenagos, the Reveler, remove a payoff, enable lethal, or disable an activated ability. Card text check required for Ancient Grudge and Destructive Revelry target restrictions; do not assume they answer arbitrary spells.

- Cast instant-speed interaction before resolution when waiting loses the answer window. Destroy a sacrifice outlet, mana artifact, equipment, prison artifact, or enchantment engine before its controller untaps or activates it if Forge shows the legal action now and no better target is likely this turn.

- Let low-impact spells resolve when holding up mana enables a larger response. Preserve Ancient Grudge, Artifact Mutation, Destructive Revelry, Ground Assault, and Atarka's Command for cards that change combat, mana, or payoff access; do not trade them for small value permanents unless the board state says that small permanent is the clock or engine.

- Treat optional payments and activated abilities as commitment gates. Pay for extort-like, copy-like, pump, filter, sacrifice, or untap choices only when Forge exposes the legal option and the payment does not consume mana required for Manamorphose, Xenagos, the Reveler, a ritual chain, Ground Assault, or a payoff spell this turn.

- Use Soulbright Flamekin, Agatha of the Vile Cauldron, Ashnod's Altar, Wakeroot Elemental, and Vessel of Volatility only after checking target, cost, and timing text in the legal action. Card text check required for exact activated abilities; prefer activations that immediately create mana, lethal pressure, a protected blocker, or a decisive payoff rather than speculative value.

- Fire Benefactor's Draught at the combat or mana window where untapping creatures changes the result. Use it after blocks or during a creature-mana chain only if legal actions show that untapped Birds of Paradise, Radha, Heir to Keld, Ruby, Daring Tracker, tokens, or large creatures materially change survival, mana, or damage.

- Sequence rituals in response-aware order when the opponent can interact. Prefer lower-commitment mana first, then Manamorphose for colors, then Seething Song, Pyretic Ritual, Infernal Plunge, Geosurge, Vessel of Volatility, Priest of Urabrask, or Xenagos, the Reveler mana once the payoff is ready; do not sacrifice a creature to Infernal Plunge until the follow-up spell is legal and worth the material.

- Use Wrenn and Six, Xenagos, the Reveler, and Doubling Season with stack awareness. Resolve Doubling Season before planeswalker loyalty commitments when legal and relevant, but do not tap low for it into visible pressure if Xenagos, the Reveler or Wrenn and Six must be protected first.

## Sideboard Map

- Sideboard status: the registered sideboard contains no cards, so Veles must not create any executable sideboard plan for this list. Any between-game route should preserve the submitted main-deck configuration exactly and should reject any `add from reserve:` candidate because there is no legal registered sideboard inventory.

- Validation status: the active Oathbreaker contract reports this deck as 60 main / 0 sideboard, while the required command-zone deck size is exactly 60 singleton main-deck cards outside basic lands.the repaired Xenagos source is a legal 60-card no-sideboard Oathbreaker registration.

- Exact plan availability: no balanced explicit plan exists because `add from reserve:` may name only registered sideboard cards and this deck has none. Do not invent sideboard access to artifact hate, graveyard hate, protection, tutors, ramp, sweepers, or utility cards that are not in the registered sideboard.

- Add role cards: none. The legal sideboard pool is empty, so post-game strategic adjustment must come from mulligan discipline, command-zone timing with Xenagos, the Reveler and Manamorphose, and changed priority rules for main-deck cards already present.

- Reduce main-deck emphasis: none by sideboard action. The pilot may change how highly it values narrow main-deck cards in play, but it cannot alter the registered deck between games through the sideboard system.

- Artifact-heavy opponents: keep the main-deck artifact interaction plan active rather than searching for nonexistent sideboard upgrades. Ancient Grudge, Artifact Mutation, Destructive Revelry, Ancient Grudge, and Destructive Revelry are the only registered cards that may answer artifact-like or narrow permanent problems when legal action text confirms a target; Card text check required for Ancient Grudge and Destructive Revelry target restrictions.

- Enchantment or prison opponents: preserve Destructive Revelry and Artifact Mutation style interaction for visible permanents that stop mana production, planeswalker activation, creature combat, or payoff resolution. Do not spend those effects on low-impact permanents if the same game state shows Xenagos, the Reveler, Wrenn and Six, Gaea's Cradle, Nykthos, Shrine to Nyx, or a large creature line needs protection from a more important permanent.

- Fast creature opponents: shift post-game play patterns toward survival without assuming a sideboard package exists. Value Birds of Paradise, Tinder Wall, Ruby, Daring Tracker, Radha, Heir to Keld, Gallia of the Endless Dance, Wakeroot Elemental, and token production as blockers only when blocking preserves access to a larger stabilizing turn; use Ground Assault, Atarka's Command, Benefactor's Draught, or Artifact Mutation only according to legal targets and visible combat math.

- Control or permission opponents: change commitment timing rather than deck composition. Hold burst mana such as Seething Song, Pyretic Ritual, Geosurge, Infernal Plunge, Vessel of Volatility, Priest of Urabrask, and Manamorphose until a payoff is legal and the visible stack or known information suggests waiting is worse than acting now.

- Graveyard-focused opponents: no registered sideboard graveyard hate exists, so do not route decisions as though a graveyard bullet can appear after Game 1. Race with Xenagos, the Reveler mana, Wrenn and Six value, Reap the Past recursion, and large threats such as Woodfall Primus, Vorinclex, Voice of Hunger, Colossus of Akros, Spawnsire of Ulamog, Last March of the Ents, and Worldsoul's Rage while using main-deck interaction only when legal targets matter.

- Combo opponents: post-game adjustment should favor faster keeps and lower hesitation, not a sideboard plan. Mulligan toward early mana, Manamorphose color fixing, Xenagos, the Reveler access, and a credible payoff chain; keep Ancient Grudge, Destructive Revelry, Artifact Mutation, Ancient Grudge or Destructive Revelry only when the opponent's revealed or public plan makes the target class relevant.

- Removal-heavy opponents: protect the ramp engine by sequencing redundant mana before fragile creature commitments when possible. Birds of Paradise, Ruby, Daring Tracker, Radha, Heir to Keld, Tinder Wall, Priest of Urabrask, Soulbright Flamekin, and Agatha of the Vile Cauldron are vulnerable sources of velocity; do not sacrifice or expose them for Infernal Plunge, Ashnod's Altar, or combat unless the follow-up legal action is worth losing the body.

- Board-stall opponents: lean harder on scalable main-deck engines because no sideboard breaker is available. Xenagos, the Reveler, Doubling Season, Nykthos, Shrine to Nyx, Gaea's Cradle, Wakeroot Elemental, Ashnod's Altar, Soulbright Flamekin, Ashnod's Altar, Reap the Past, and Last March of the Ents become more important when the visible game is about repeated mana conversion rather than early racing.

- Color-pressure opponents: use sideboard downtime to re-evaluate mulligan and land policies only. Prioritize Command Tower, Cragcrown Pathway // Timbercrown Pathway, Gruul Turf, Temple of Abandon, Wooded Foothills, Attune with Aether, Caravan Vigil, Abundant Harvest, Barbed Sextant, and Manamorphose according to the hand's missing color and the legal action list.

- Post-game reflection rule: record which main-deck roles were too narrow, but do not express those notes as executable sideboard changes for this registered build. Useful tuning candidates may include whether Ancient Grudge, Artifact Mutation, Destructive Revelry, Ancient Grudge, Destructive Revelry, Ground Assault, Benefactor's Draught, or other narrow cards matched the observed metagame, but Veles must keep those notes outside the sideboard action system.

- Runtime enforcement rule: if the API asks for sideboarding with this registration, submit an empty, preservation-only plan when that is the legal representation.the repaired Xenagos source is a legal 60-card no-sideboard Oathbreaker registration.

## Matchup Guidance

- Aggro: prioritize life-preserving mana development over speculative burst turns when the opponent presents early attackers. Keep hands that can deploy Birds of Paradise, Tinder Wall, Ruby, Daring Tracker, Radha, Heir to Keld, Burgeoning, Attune with Aether, Caravan Vigil, Barbed Sextant, or Manamorphose early, then convert Xenagos, the Reveler into mana or blockers only when the legal activation stabilizes the next combat. Use Ground Assault, Atarka's Command, Artifact Mutation, Benefactor's Draught, and Wakeroot Elemental only from visible legal action text and combat math; Card text check required for exact Ground Assault and Benefactor's Draught combat implications.

- Control: wait to commit burst mana until a payoff chain is already legal or the visible clock makes waiting worse. Seething Song, Pyretic Ritual, Geosurge, Infernal Plunge, Vessel of Volatility, Priest of Urabrask, Manamorphose, and Xenagos, the Reveler should normally be bundled with a threat or recursion spell rather than spent into an empty board. Against open interaction, prefer resilient value from Wrenn and Six, Reap the Past, Abundant Harvest, Barbed Sextant, and Big Score, and land drops before exposing Doubling Season, Vorinclex, Voice of Hunger, Last March of the Ents, Colossus of Akros, Spawnsire of Ulamog, or Woodfall Primus.

- Combo: race with the fastest credible mana-to-payoff line and spend narrow interaction only on visible combo-enabling permanents. Mulligan toward Command Tower, Cragcrown Pathway // Timbercrown Pathway, Temple of Abandon, Wooded Foothills, Birds of Paradise, Tinder Wall, Burgeoning, Manamorphose, Pyretic Ritual, Seething Song, Xenagos, the Reveler, and one decisive payoff. Ancient Grudge, Artifact Mutation, Destructive Revelry, Ancient Grudge, and Destructive Revelry should be held when public information shows an artifact, enchantment, or narrow target class that matters; Card text check required for Ancient Grudge and Destructive Revelry restrictions.

- Tempo: value mana efficiency and threat timing over maximum size. Do not use a whole turn on Abundant Harvest, Barbed Sextant, Benefactor's Draught, Reap the Past, or a slow activated ability if the opponent can punish the tempo loss with pressure plus interaction. Favor one-spell turns that improve mana and board at the same time, such as Birds of Paradise into Xenagos, the Reveler access, Ruby, Daring Tracker into extra land pressure, Radha, Heir to Keld with attack mana, or Wrenn and Six recurring Wooded Foothills if legal.

- Midrange: win by going over the board, not by trading every card one-for-one. Preserve Gaea's Cradle, Nykthos, Shrine to Nyx, Xenagos, the Reveler, Doubling Season, Ashnod's Altar, Agatha of the Vile Cauldron, Soulbright Flamekin, and Wakeroot Elemental for scalable turns when the board stalls. Use Ground Assault, Destructive Revelry, Ancient Grudge, Artifact Mutation, and Atarka's Command on permanents or combat states that block the ramp plan, not merely on the first legal target.

- Big mana: identify whether this deck is faster, wider, or more disruptive from the visible board. If ahead, commit Xenagos, the Reveler, ritual mana, Gaea's Cradle, Nykthos, Shrine to Nyx, Geosurge, and Last March of the Ents before the opponent's larger engine comes online. If behind, prioritize Woodfall Primus, Vorinclex, Voice of Hunger, Reap the Past, Worldsoul's Rage, and Artifact Mutation or Destructive Revelry against visible mana engines. Card text check required for exact Worldsoul's Rage targeting and scaling decisions.

- Graveyard: race first because the registered deck has no dedicated graveyard hate. Treat Reap the Past as your own recovery engine, not as interaction, and do not hold up nonexistent graveyard answers. Use Wrenn and Six, Wooded Foothills, Big Score, Abundant Harvest, Barbed Sextant, Abundant Harvest, and Manamorphose to keep resources flowing while advancing toward Woodfall Primus, Vorinclex, Voice of Hunger, Colossus of Akros, Spawnsire of Ulamog, or Last March of the Ents. Ancient Grudge may matter from graveyard text if Forge exposes a legal action; Card text check required before assuming flashback timing.

- Artifact/enchantment: make the opponent prove the target matters before spending the deck's narrow answers. Ancient Grudge, Artifact Mutation, Destructive Revelry, Ancient Grudge, and Destructive Revelry are premium only when legal target text and visible board state show mana denial, lock pressure, lethal setup, or a protected engine. Against artifact creature boards, Artifact Mutation may be both removal and board development if the rules engine exposes a legal target and token result; Card text check required for exact token count and target class.

- Go-wide: stabilize with blockers, scalable mana, and sweep-like effects before chasing a single giant threat. Xenagos, the Reveler token production, Artifact Mutation tokens, Wakeroot Elemental, Birds of Paradise, Tinder Wall, Ruby, Daring Tracker, Radha, Heir to Keld, Gallia of the Endless Dance, and Priest of Urabrask can buy time when blocking preserves a later payoff. Ground Assault and Atarka's Command should be considered when legal action text indicates a board-wide or combat-relevant mode; Card text check required for exact damage, prevention, and mode text.

- Single-threat: answer or race the visible threat based on clock and blockers. Ground Assault is a priority if land count makes it lethal to the threat and Forge exposes the target. Woodfall Primus, Destructive Revelry, Ancient Grudge, Artifact Mutation, and Destructive Revelry should be held for target classes they can legally hit. If removal is unavailable, use Colossus of Akros, Vorinclex, Voice of Hunger, Spawnsire of Ulamog, Last March of the Ents, Wakeroot Elemental, or Xenagos, the Reveler to create a larger board before the single threat ends the game.

- Burn: treat life total as the main resource and reduce unnecessary shock-window exposure from slow setup. Keep hands with early mana and action; avoid hands that need multiple non-impact turns from Abundant Harvest, Barbed Sextant, Benefactor's Draught, or Reap the Past before affecting board or life. Atarka's Command may be tactically important in burn mirrors or life-gain prevention contexts, but Card text check required before relying on a mode. Benefactor's Draught requires Card text check; choose it only if legal action text confirms immediate survival or meaningful life gain.

- Removal-heavy: diversify mana sources and avoid sacrificing the only creature that keeps the hand functional. Birds of Paradise, Ruby, Daring Tracker, Radha, Heir to Keld, Tinder Wall, Priest of Urabrask, Soulbright Flamekin, Gallia of the Endless Dance, Rodeo Pyromancers, and Agatha of the Vile Cauldron should not be exposed in combat or cashed into Infernal Plunge or Ashnod's Altar unless the follow-up legal action creates a strong board, resolves Xenagos, the Reveler, or casts a payoff. Favor land-based engines such as Gaea's Cradle, Nykthos, Shrine to Nyx, Gruul Turf, Command Tower, and Wrenn and Six when creatures are dying repeatedly.

- Unknown opponents: mulligan for mana plus a plan, not for narrow interaction. A strong unknown keep has two usable mana sources or a mana source plus Attune with Aether, Caravan Vigil, Abundant Harvest, Barbed Sextant, or Manamorphose, plus either Xenagos, the Reveler access, Wrenn and Six, a ritual chain, or a payoff. A weak unknown keep contains only Ancient Grudge, Ancient Grudge, Destructive Revelry, Ground Assault, Benefactor's Draught, or expensive threats without acceleration.

- Runtime constraint: change matchup posture through priorities, not sideboarding. This registration has no sideboard, so all matchup adjustments must come from mulligans, sequencing, target discipline, and commitment gates using only main-deck cards and legal actions exposed by the rules engine.

## Specific Matchup Notes
- General/archetype-only: exact opponents are absent, so revealed cards, legal target text, stack state, and public board position override every assumption here. Sideboarding is unavailable because the registered sideboard is empty; all matchup adaptation must come from mulligans, sequencing, target discipline, and whether to commit Xenagos, the Reveler, rituals, Doubling Season, or a large creature.

- Against fast creature pressure: prioritize early mana that also blocks or trades, then stabilize into a larger board. Birds of Paradise, Tinder Wall, Ruby, Daring Tracker, Radha, Heir to Keld, Priest of Urabrask, Gallia of the Endless Dance, and Xenagos, the Reveler tokens matter more than slow card selection if life is under pressure. Priority targets are creatures enabling lethal attacks, evasive threats, and artifacts or enchantments that multiply combat damage; use Ground Assault, Atarka's Command, Artifact Mutation, or Destructive Revelry only when the legal action text matches the visible problem. Card text check required for Ground Assault and Atarka's Command mode certainty.

- Against control or removal-heavy decks: commit in layers and avoid making one answered permanent represent the whole turn. Prefer Wrenn and Six, land drops, Gruul Turf, Gaea's Cradle, Nykthos, Shrine to Nyx, Barbed Sextant, Manamorphose, and small creatures before spending Geosurge, Seething Song, Pyretic Ritual, Infernal Plunge, or Vessel of Volatility on a payoff that can be answered cleanly. Priority targets are visible lock pieces, mana denial, and interaction engines; Ancient Grudge, Destructive Revelry, Ancient Grudge, Destructive Revelry, and Artifact Mutation require legal target confirmation before use.

- Against artifact or enchantment engines: conserve narrow interaction until a visible permanent changes mana, combat, or inevitability. Ancient Grudge, Artifact Mutation, Destructive Revelry, Ancient Grudge, and Destructive Revelry should answer a high-impact target rather than the first legal target. If Artifact Mutation can legally remove an artifact creature or artifact engine while creating board material, consider it a ramp-to-combat bridge; Card text check required for exact token output and target class.

- Against big mana or slower battlefield decks: become the proactive engine and force the opponent to answer mana conversion. Xenagos, the Reveler, Gaea's Cradle, Nykthos, Shrine to Nyx, Doubling Season, Soulbright Flamekin, Wakeroot Elemental, Ashnod's Altar, and Agatha of the Vile Cauldron are priority setup cards when the opponent is not pressuring life. Priority targets are opposing mana engines and permanents that beat Colossus of Akros, Woodfall Primus, Vorinclex, Voice of Hunger, Spawnsire of Ulamog, Last March of the Ents, or Worldsoul's Rage.

- Against graveyard or recursion decks: race with board pressure because the registration has no dedicated graveyard hate. Do not hold mana for nonexistent graveyard answers; use Abundant Harvest, Attune with Aether, Caravan Vigil, Abundant Harvest, Barbed Sextant, Big Score, Manamorphose, and Wrenn and Six to keep mana and cards flowing toward a closer. Ancient Grudge may have graveyard utility only if the rules engine exposes a legal action; Card text check required before relying on it.

- Against burn or reach-heavy decks: preserve life and board presence over slow sculpting. Benefactor's Draught and Atarka's Command may be relevant only if legal action text confirms the survival mode or damage-race mode. Avoid spending turns on Abundant Harvest, Barbed Sextant, Reap the Past, or non-impact activations if the visible clock makes a payoff turn unlikely.

## Risk Summary
- Mana risk: the deck can draw explosive red rituals without enough green, green setup without red conversion, or creature-mana hands vulnerable to removal. Keep hands that can cast early green selection or mana creatures and still reach Xenagos, the Reveler, Manamorphose, or a payoff; be suspicious of hands that rely on only Gaea's Cradle, Nykthos, Shrine to Nyx, Gruul Turf, or one creature surviving.

the repaired Xenagos source is a legal 60-card no-sideboard Oathbreaker registration. Treat games as testing only until the rules engine and deck validator accept the registration.

- Matchup risk: no sideboard means narrow answers cannot be increased for artifacts, enchantments, graveyards, burn, or control. Priority discipline must replace sideboarding; do not spend Ancient Grudge, Artifact Mutation, Destructive Revelry, Ancient Grudge or Destructive Revelry unless the visible target matters.

- Draw risk: expensive closers can strand early hands, while cheap cantrips and artifacts can fail to affect the board. Abundant Harvest, Attune with Aether, Caravan Vigil, Barbed Sextant, Abundant Harvest, Manamorphose, and Big Score should be used to fix the next decision, not to delay necessary board development.

- Over-sideboarding risk: there is no registered sideboard, so any runtime instruction to add cards is illegal. Reject sideboard actions that name cards outside the registered main deck or imply a sideboard plan.

- Graveyard risk: opposing graveyard engines may outscale this list because it lacks dedicated hate. Race, attack mana, and use Reap the Past only as recovery for this deck's resources.

- Sweeper/removal risk: creature-based mana and token plans can collapse to removal. Avoid sacrificing Birds of Paradise, Tinder Wall, Ruby, Daring Tracker, Radha, Heir to Keld, Priest of Urabrask, or tokens unless the same turn produces a payoff or materially changes the board.

- Closer risk: Colossus of Akros, Woodfall Primus, Vorinclex, Voice of Hunger, Spawnsire of Ulamog, Last March of the Ents, and Worldsoul's Rage are powerful but can be too slow or poorly timed. Commit only when mana, board, and visible interaction make waiting worse.

- Interaction risk: several answers have restrictive target classes or uncertain text. Card text check required for Destructive Revelry, Ancient Grudge, Ground Assault, Benefactor's Draught, Atarka's Command, and Worldsoul's Rage before assuming a mode or target.

- Sequencing risk: ritual mana, Ashnod's Altar, Infernal Plunge, Vessel of Volatility, Geosurge, Seething Song, and Pyretic Ritual punish premature commitment. Plan the full legal chain before taking mana actions, and stop if Forge exposes a new stack, target, or payment prompt that changes the line.

## Test Feedback Checklist
- Deciding factor: Which exact turn changed the game, and was it a mana explosion from Geosurge, Seething Song, Pyretic Ritual, Infernal Plunge, Vessel of Volatility, Xenagos, the Reveler, Gaea's Cradle, or Nykthos, Shrine to Nyx, or was it a missed pressure/removal window?
- Mulligans: Did the opening hand have castable early development from Forest, Mountain, Command Tower, Cragcrown Pathway // Timbercrown Pathway, Birds of Paradise, Tinder Wall, Abundant Harvest, Attune with Aether, Caravan Vigil, Barbed Sextant, or Abundant Harvest, and did the keep actually produce action by turn two?
- Mana: Did Gruul Turf, Temple of Abandon, Wooded Foothills, Wrenn and Six, Manamorphose, Barbed Sextant, and land-finding spells solve colors, or did rituals strand green payoffs or green setup strand red burst mana?
- Velocity: Did Abundant Harvest, Attune with Aether, Caravan Vigil, red-green creature selection spell, Signal the Clans, Big Score, Abundant Harvest, Barbed Sextant, Benefactor's Draught, and Manamorphose improve the next decision, or did they spend mana without adding board, cards, or lethal setup?
- Engine performance: Did Xenagos, the Reveler, Doubling Season, Ashnod's Altar, Agatha of the Vile Cauldron, Soulbright Flamekin, Wakeroot Elemental, Ruby, Daring Tracker, Radha, Heir to Keld, Gallia of the Endless Dance, Priest of Urabrask, and Burgeoning create material that survived long enough to matter?
- Removal timing: Did Ground Assault, Ancient Grudge, Artifact Mutation, Destructive Revelry, Ancient Grudge, Destructive Revelry, Ground Assault, Atarka's Command, or Worldsoul's Rage answer a visible high-impact permanent, or was interaction fired into a low-impact target because it was merely legal?
- Closing: Did Colossus of Akros, Woodfall Primus, Vorinclex, Voice of Hunger, Spawnsire of Ulamog, Last March of the Ents, Reap the Past, Worldsoul's Rage, or Wakeroot Elemental end the game after the deck committed burst mana, or did a closer sit stranded after rituals were spent?
- Role accuracy: Did the pilot correctly choose between racing, stabilizing, building an engine, and holding interaction, or did it keep following ramp lines after the visible clock demanded blockers or removal?
- Mistakes: Did any action sacrifice Birds of Paradise, Tinder Wall, tokens, or another mana body to Ashnod's Altar or Infernal Plunge before the same turn produced a payoff?
- Stranded cards: Which cards were uncastable or irrelevant most often: Geosurge, Last March of the Ents, Colossus of Akros, Spawnsire of Ulamog, Vorinclex, Voice of Hunger, Destructive Revelry, Ancient Grudge, Benefactor's Draught, or Ground Assault?
- Overperformers and underperformers: Which exact cards produced wins, stabilized losses, or failed despite being drawn, and was any result dependent on uncertain text requiring Card text check required?
- Sideboard: Did the absence of a registered sideboard lose games against artifacts, enchantments, graveyards, burn, control, or fast combat, and did any attempted sideboard action correctly fail as illegal?

## First Tuning Questions
- Legality first: Which repaired-list cards or roles most often underperformed in logged games?
- Mana base: Does the deck need more reliable green and red access before it can justify Gaea's Cradle, Nykthos, Shrine to Nyx, Gruul Turf, Geosurge, Seething Song, Pyretic Ritual, and Infernal Plunge in the same shell?
- Early setup: Are Birds of Paradise, Tinder Wall, Ruby, Daring Tracker, Radha, Heir to Keld, Priest of Urabrask, Barbed Sextant, Attune with Aether, Abundant Harvest, Caravan Vigil, and Burgeoning enough early action, or are hands still passing without board development?
- Engine focus: Should the list emphasize Xenagos, the Reveler plus Doubling Season and creature mana, or should it reduce engine pieces that require multiple permanents before producing a decisive payoff?
- Ritual package: Are Geosurge, Seething Song, Pyretic Ritual, Infernal Plunge, Vessel of Volatility, Priest of Urabrask, and Manamorphose winning immediately often enough, or are they creating one-turn exposure to removal and counterplay?
- Closer mix: Are Colossus of Akros, Woodfall Primus, Vorinclex, Voice of Hunger, Spawnsire of Ulamog, Last March of the Ents, Worldsoul's Rage, and Reap the Past too many expensive endpoints for a 60-card configuration?
- Interaction mix: Are Ancient Grudge, Artifact Mutation, Destructive Revelry, Ancient Grudge, Destructive Revelry, Ground Assault, and Atarka's Command too narrow or text-dependent for maindeck slots, given there is no sideboard?
- Aggro plan: Does the deck need more survival structure if fast creatures beat it before Xenagos, the Reveler, Wakeroot Elemental, Woodfall Primus, or Vorinclex, Voice of Hunger become relevant?
- Control plan: Does the deck need more resilient incremental pressure if single answered payoffs make Geosurge, Seething Song, Pyretic Ritual, Infernal Plunge, and Vessel of Volatility poor topdecks?
- Role conflict: Is the deck trying to be ritual combo, creature-ramp midrange, artifact engine, and narrow-answer control at once, and which role produced the most actual wins in logs?
- Sideboard slots: If the format configuration later permits a sideboard or companion test pool, which matchups most need added role cards, and which main-deck emphases should be reduced without violating the registered deck constraints?

## Veles Tactical Policy

### Policy: Opening Hand Functional Ramp Gate
Priority: High
Decision families: mulligan
Cards: Xenagos, the Reveler; Manamorphose; Birds of Paradise; Tinder Wall; Abundant Harvest; Attune with Aether; Caravan Vigil; Barbed Sextant; Barbed Sextant; Abundant Harvest; Burgeoning
Phase windows: opening hand, mulligan, first draw step
Runtime cues: mulligan prompt; opening hand visible
Use when: evaluating keep versus mulligan before any game action.
Avoid when: Forge has advanced beyond the mulligan decision.
Instructions: Keep hands with two usable mana sources or one land plus a castable fixer/ramp spell and a path to Xenagos, the Reveler, ritual acceleration, or early selection. Mulligan hands that cannot produce green or red actions by turn two unless the legal London mulligan context shows a superior risk from going lower.
Pilot skill floor: light-model
No-API allowed: no
Light-model allowed: yes

### Policy: First Enabling Permanent Setup
Priority: Medium
Decision families: mana; priority
Cards: Birds of Paradise; Tinder Wall; Ruby, Daring Tracker; Radha, Heir to Keld; Burgeoning; Barbed Sextant; Barbed Sextant; Abundant Harvest
Phase windows: precombat main, postcombat main, early turns
Runtime cues: legal cast/play actions for named setup cards
Use when: choosing the first development play while no decisive payoff is available.
Avoid when: an immediate survival interaction or winning mana chain is already legal.
Instructions: Establish a mana creature, cheap fixer, or selection permanent before spending rituals. Prefer development that increases next-turn green/red access and leaves future command-zone Manamorphose plus Xenagos, the Reveler lines intact.
Pilot skill floor: light-model
No-API allowed: no
Light-model allowed: yes

### Policy: Land And Color Sequencing
Priority: Medium
Decision families: mana; selection
Cards: Command Tower; Cragcrown Pathway // Timbercrown Pathway; Temple of Abandon; Gruul Turf; Wooded Foothills; Forest; Mountain; Gaea's Cradle; Nykthos, Shrine to Nyx
Phase windows: main phases, land-play prompts, fetch prompts
Runtime cues: legal land play or mana ability actions
Use when: selecting a land play or mana source for a non-lethal turn.
Avoid when: a deterministic payment prompt has only one legal source set.
Instructions: Prioritize untapped access to the colors required by visible hand and command-zone actions. Delay Gruul Turf if returning a land would prevent the current turn's legal development; deploy Gaea's Cradle and Nykthos, Shrine to Nyx when visible creature count or devotion makes them real mana engines.
Pilot skill floor: light-model
No-API allowed: no
Light-model allowed: yes

### Policy: Deterministic Command Signature Cast
Priority: Medium
Decision families: mana; priority
Cards: Manamorphose
Phase windows: main phases, priority with legal cast action
Runtime cues: action:cast Manamorphose
Use when: Manamorphose is the selected legal action and the pilot has already committed to using it for color conversion or storm-like velocity this turn.
Avoid when: the turn plan has not chosen whether to spend command-zone access.
Instructions: Execute the visible cast action only after the broader turn plan selected Manamorphose; choose colors from the following mana prompt according to currently visible costs and legal follow-up actions.
Pilot skill floor: no-api
No-API allowed: yes
Light-model allowed: yes

### Policy: Manamorphose Color Choice
Priority: Medium
Decision families: mana
Cards: Manamorphose; Xenagos, the Reveler; Geosurge; Seething Song; Pyretic Ritual; Last March of the Ents; Woodfall Primus; Vorinclex, Voice of Hunger; Wakeroot Elemental
Phase windows: mana choice prompt after Manamorphose
Runtime cues: action:choose color
Use when: a Manamorphose color-choice prompt is visible and the next intended spell costs are visible in hand or command zone.
Avoid when: the next intended spell has not been selected.
Instructions: Choose the color pair that pays for the next legal payoff or setup spell shown by Forge. Do not invent future draws; use visible hand, command zone, floating mana, and legal actions only.
Pilot skill floor: light-model
No-API allowed: no
Light-model allowed: yes

### Policy: Ritual Burst Commitment Gate
Priority: High
Decision families: mana; priority
Cards: Geosurge; Seething Song; Pyretic Ritual; Infernal Plunge; Vessel of Volatility; Priest of Urabrask; Tinder Wall; Ashnod's Altar
Phase windows: main phases, priority before spending burst mana
Runtime cues: legal ritual, sacrifice, or mana-storage activation actions
Use when: deciding whether to start a one-turn mana chain.
Avoid when: a ritual action is already part of a deterministic selected chain and no new information appeared.
Instructions: Commit burst mana only when visible follow-up actions convert it into Xenagos, the Reveler, a decisive permanent, lethal pressure, or a clear stabilizer. Reject lines that sacrifice the only mana body or consume all colored sources without a visible payoff.
Pilot skill floor: light-model
No-API allowed: no
Light-model allowed: yes

### Policy: Exact Ritual Execution After Commitment
Priority: Medium
Decision families: mana
Cards: Seething Song; Pyretic Ritual; Priest of Urabrask; Vessel of Volatility
Phase windows: main phases, mana ability or cast prompt
Runtime cues: action:cast Seething Song; action:cast Pyretic Ritual; action:activate Vessel of Volatility
Use when: the current legal action text exactly matches the next ritual in a selected mana chain.
Avoid when: multiple ritual orders remain tactically distinct.
Instructions: Take the exact selected ritual action and continue to the next Forge prompt; stop for light-model reasoning if a target, sacrifice, counterspell, or new stack object appears.
Pilot skill floor: no-api
No-API allowed: yes
Light-model allowed: yes

### Policy: Sacrifice Cost Gate
Priority: High
Decision families: mana; priority
Cards: Infernal Plunge; Ashnod's Altar; Birds of Paradise; Tinder Wall; Priest of Urabrask; Xenagos, the Reveler
Phase windows: cost payment prompts, main phases
Runtime cues: sacrifice candidate prompt; legal sacrifice action
Use when: Forge asks for a sacrifice or offers Ashnod's Altar activation.
Avoid when: the sacrificed object is a temporary token and the same visible line immediately casts the selected payoff.
Instructions: Preserve unique color sources and engine bodies unless the sacrificed object directly funds the selected payoff this turn. Sacrifice expendable tokens before Birds of Paradise or other persistent mana sources when legal text shows equivalent payment.
Pilot skill floor: light-model
No-API allowed: no
Light-model allowed: yes

### Policy: Xenagos Commitment Gate
Priority: High
Decision families: mana; priority
Cards: Xenagos, the Reveler; Doubling Season; Birds of Paradise; Ruby, Daring Tracker; Radha, Heir to Keld; Gallia of the Endless Dance; Wrenn and Six
Phase windows: main phases with planeswalker cast or activation actions
Runtime cues: legal cast or activate action for Xenagos, the Reveler
Use when: deciding whether to tap low for Xenagos, the Reveler or activate him.
Avoid when: visible lethal or survival interaction overrides engine development.
Instructions: Cast or invest in Xenagos, the Reveler when he produces immediate mana, bodies, or a protected next-turn payoff from visible board state. Treat Doubling Season as a fragile amplifier, not a reason to ignore a visible attack that can remove Xenagos.
Pilot skill floor: light-model
No-API allowed: no
Light-model allowed: yes

### Policy: Doubling Season Engine Gate
Priority: Medium
Decision families: mana; priority
Cards: Doubling Season; Xenagos, the Reveler; Wakeroot Elemental; Ashnod's Altar; Agatha of the Vile Cauldron
Phase windows: main phases
Runtime cues: legal cast action for Doubling Season or engine permanents
Use when: choosing between engine setup and immediate board impact.
Avoid when: opponent has a visible lethal clock and a stabilizing action is legal.
Instructions: Commit Doubling Season or activated-ability engines when the visible board can survive a tempo turn or the same turn converts them into mana, counters, tokens, or lethal pressure. Card text check required for unfamiliar activation reductions or copy effects.
Pilot skill floor: light-model
No-API allowed: no
Light-model allowed: yes

### Policy: Big Payoff Commitment Gate
Priority: High
Decision families: mana; priority
Cards: Colossus of Akros; Woodfall Primus; Vorinclex, Voice of Hunger; Spawnsire of Ulamog; Last March of the Ents; Reap the Past; Worldsoul's Rage
Phase windows: main phases, high-mana turns
Runtime cues: legal cast action for named payoff cards
Use when: choosing the expensive endpoint for a committed ramp turn.
Avoid when: the payoff is uncastable after visible taxes or color requirements.
Instructions: Choose the payoff that immediately stabilizes, attacks the opponent's resources, or closes fastest from visible board state. Do not spend rituals on an expensive card that leaves the deck empty-handed and behind unless waiting loses to the visible clock.
Pilot skill floor: light-model
No-API allowed: no
Light-model allowed: yes

### Policy: Removal And Hate Target Gate
Priority: High
Decision families: interaction; priority
Cards: Ground Assault; Ancient Grudge; Artifact Mutation; Destructive Revelry; Ancient Grudge; Destructive Revelry; Ground Assault; Atarka's Command; Worldsoul's Rage
Phase windows: any legal priority window, combat trick windows, opponent main phases
Runtime cues: legal cast action with target prompt for named interaction
Use when: deciding whether to spend interaction on a visible permanent, spell, or combat state.
Avoid when: the card text or target legality is uncertain and no immediate threat is visible.
Instructions: Use interaction to prevent lethal damage, stop a visible lock piece, remove a blocker for lethal, or protect a committed payoff turn. Card text check required for narrow color, artifact, enchantment, damage, and command modes before assuming a target solves the problem.
Pilot skill floor: light-model
No-API allowed: no
Light-model allowed: yes

### Policy: Exact Artifact Destruction Target
Priority: Medium
Decision families: interaction
Cards: Ancient Grudge; Artifact Mutation; Destructive Revelry
Phase windows: target prompt after selected artifact interaction
Runtime cues: action:target opponent
Use when: the selected spell is Ancient Grudge, Artifact Mutation, or Destructive Revelry and exactly one opponent-controlled artifact is a legal target.
Avoid when: multiple legal targets are visible.
Instructions: Choose the single legal opponent artifact target and continue to resolution. If Forge exposes multiple artifacts, route target selection through light-model reasoning.
Pilot skill floor: no-api
No-API allowed: yes
Light-model allowed: yes

### Policy: Selection Before Commitment
Priority: Medium
Decision families: selection; mana; priority
Cards: Abundant Harvest; Attune with Aether; Caravan Vigil; Signal the Clans; Barbed Sextant; Big Score; Benefactor's Draught; Reap the Past
Phase windows: main phases, selection prompts, end step with instant-speed legal actions
Runtime cues: legal selection, draw, discard, search, or reveal actions
Use when: the turn lacks a committed payoff and selection can change land, color, or payoff availability.
Avoid when: spending mana on selection prevents a visible survival action or selected payoff.
Instructions: Use cheap selection before land drops or rituals when it can reveal lands, colors, or action density. Route Signal the Clans, Reap the Past, discard, and search choices through light-model because target and pile decisions depend on visible needs.
Pilot skill floor: light-model
No-API allowed: no
Light-model allowed: yes

### Policy: Combat Pressure And Block Discipline
Priority: Medium
Decision families: combat
Cards: Gallia of the Endless Dance; Radha, Heir to Keld; Ruby, Daring Tracker; Woodfall Primus; Vorinclex, Voice of Hunger; Colossus of Akros; Spawnsire of Ulamog; Wakeroot Elemental
Phase windows: declare attackers, declare blockers, combat damage windows
Runtime cues: legal attack or block prompts
Use when: evaluating attacks, blocks, or post-block priority.
Avoid when: exactly one legal combat action exists and Forge labels it mandatory.
Instructions: Attack when the creature's damage, trigger, or planeswalker pressure advances the current role without exposing required mana bodies. Block to preserve life or Xenagos, the Reveler when the visible crack-back beats the ramp plan.
Pilot skill floor: light-model
No-API allowed: no
Light-model allowed: yes

### Policy: One Legal Pass After No Action
Priority: Low
Decision families: priority
Cards: none
Phase windows: priority windows with empty stack
Runtime cues: action:pass
Use when: the only legal non-mana action is pass and the stack is empty.
Avoid when: any cast, activate, attack, block, target, or payment action is also legal.
Instructions: Pass the priority window and let Forge advance. Do not use this policy when the deck can act or when a visible opponent spell is on the stack.
Pilot skill floor: no-api
No-API allowed: yes
Light-model allowed: yes

### Policy: Stack Response Window
Priority: High
Decision families: priority; interaction
Cards: Ancient Grudge; Destructive Revelry; Ancient Grudge; Destructive Revelry; Atarka's Command; Benefactor's Draught; Big Score
Phase windows: opponent spell on stack, end step, combat priority
Runtime cues: visible stack object; legal instant-speed action
Use when: deciding whether to respond before a spell or combat step resolves.
Avoid when: legal action text does not indicate a relevant response and passing preserves a stronger visible line.
Instructions: Respond only when the visible stack object threatens the ramp engine, payoff, life total, or planeswalker, or when end-step card velocity is clearly available without sacrificing next-turn mana. Card text check required for narrow response cards.
Pilot skill floor: light-model
No-API allowed: no
Light-model allowed: yes

### Policy: No Registered Sideboard
Priority: Low
Decision families: sideboard
Cards: none
Phase windows: sideboard step, between games
Runtime cues: sideboard request; registered sideboard count 0
Use when: Forge or Veles asks for sideboarding with this registered list.
Avoid when: a future registered sideboard is provided by deck validation.
Instructions: Submit no changes and preserve the registered main deck. Treat any requested sideboard card movement as illegal because the registered sideboard is empty.
