# Strategy Specifications
## Deck Name And Archetype
Blue Artifacts is a Legacy 60-card main deck with a 15-card sideboard, registered as combo, midrange, and artifact. The supplied format-aware validation contract says the deck passes Legacy construction for 60 main / 15 sideboard, so Veles should treat the submitted list as registered and legal unless the rules engine reports a runtime legality, zone, or action problem. The pilot must still obey only legal actions exposed by the engine; the guide is strategic preference, not authority over card text or legality.

Blue Artifacts should be classified as a rogue artifact-engine hybrid rather than a stock Legacy archetype. The registered shell combines graveyard-recursion pressure from Emry, Lurker of the Loch, Goblin Welder, and Goblin Engineer with fast artifact mana from Mox Opal and Lotus Petal, Saga pressure from Urza's Saga, and single-card silver bullets such as Ensnaring Bridge, Agatha's Soul Cauldron, Legion Extruder, Phyrexian Dragon Engine, Skateboard, and Tezzeret, Cruel Captain. Because several registered cards are not safe to evaluate from memory, Card text check required for Pinnacle Emissary, Sewer-veillance Cam, Skateboard, Legion Extruder, Agatha's Soul Cauldron, and Tezzeret, Cruel Captain before assigning exact activated-ability, trigger, or combo-line certainty.

The primary role is proactive artifact development with a recursive midgame, not pure draw-go control. Opening hands should be judged by whether they create early artifacts, enable Mox Opal, deploy or find Goblin Welder / Goblin Engineer / Emry, Lurker of the Loch, or pressure through Urza's Saga. Hands with only colored lands and no artifact density are suspect even if they cast a creature, because the deck's strongest turns depend on cheap artifacts entering the battlefield and graveyard.

The mana base is blue-red artifact-centric with light white access from Plateau and fetchlands, plus artifact lands Great Furnace and Seat of the Synod. Veles should track whether the visible hand actually needs blue for Emry, Lurker of the Loch, red for Goblin Welder and Goblin Engineer, white for sideboard cards, or colorless/artifact sequencing for Urza's Saga. Lotus Petal and Mox Opal are tactical resources, not automatic acceleration; spending them is best when it unlocks an engine creature, protected combo turn, urgent interaction, or tempo-critical artifact deployment.

The role split is matchup-dependent. Against fast spell combo, the deck becomes a disruptive artifact-combo deck after sideboard with Swan Song, Flusterstorm, Void Mirror, Disruptor Flute, Tormod's Crypt, Pithing Needle, and possibly Containment Priest depending on visible opposing mechanics. Against creature pressure, the deck leans midrange and stabilization with Ensnaring Bridge, Portable Hole, Sudden Demise, Haywire Mite, artifact recursion, and Urza's Saga bodies. Against slower control or fair midrange, the deck should prioritize durable engines, recursive threats, and forcing opponents to answer repeated artifacts rather than spending all resources on one fragile push.

Opponent information status is unknown unless supplied by match context, public game actions, revealed cards, or sideboard-stage metadata. The pilot must not infer exact hidden cards from archetype labels alone. When opponent cards are only metagame examples, they must stay outside policy `Cards:` fields or be prefixed as `opponent:` in later policy sections. Runtime decisions should prefer visible facts: opponent mana, graveyard, battlefield, stack, known revealed cards, hand count, clock, and legal actions returned by Veles.

## Thesis
Blue Artifacts assembles cheap artifacts, fast mana, graveyard-enabled artifact engines, and Urza's Saga pressure into a proactive Legacy game plan. The deck wants early artifact density for Mox Opal, Lotus Petal, Mishra's Bauble, Urza's Bauble, Chromatic Star, Great Furnace, Seat of the Synod, Sewer-veillance Cam, Skateboard, and Pinnacle Emissary, then converts those permanents and graveyard objects into repeated value through Emry, Lurker of the Loch, Goblin Welder, and Goblin Engineer.

Prioritize engine access over isolated card quality. A hand that makes a quick Emry, Lurker of the Loch, Goblin Welder, Goblin Engineer, or Urza's Saga with multiple artifacts is usually closer to the deck's thesis than a hand with lands and singletons but no artifact velocity. The deck wins by making recursive artifacts matter, creating Saga pressure, turning graveyard contents into battlefield resources, and eventually letting single-card payoffs such as Tezzeret, Cruel Captain, Legion Extruder, Phyrexian Dragon Engine, Agatha's Soul Cauldron, Ensnaring Bridge, or constructed artifact bodies dominate if their visible text and legal actions support that line.

Respect that several registered cards require exact text confirmation before deterministic combo claims. Card text check required for Pinnacle Emissary, Sewer-veillance Cam, Skateboard, Legion Extruder, Agatha's Soul Cauldron, and Tezzeret, Cruel Captain. Until Veles or the rules engine exposes specific legal actions, treat those cards as artifact bodies, possible engines, or possible payoffs only conditionally, and choose from visible legal action text rather than assumed oracle memory.

Do not pilot this as pure permission control or as all-in storm combo. The main deck has almost no conventional stack interaction and only Ensnaring Bridge as a clear main-deck defensive lock piece, so game-one decisions should usually develop artifacts, mana, graveyard setup, and engine creatures instead of passing with no represented action. Post-sideboard, the deck can become more interactive through Swan Song, Flusterstorm, Disruptor Flute, Void Mirror, Pithing Needle, Tormod's Crypt, Containment Priest, Portable Hole, Haywire Mite, and Sudden Demise, but those cards should supplement the artifact engine rather than replace the need to establish a board.

Prioritize visible-board leverage at runtime. Use legal actions, public zones, revealed cards, mana availability, stack contents, and opponent clock before generic archetype assumptions. When the engine offers multiple plausible lines, prefer the line that increases artifact count, preserves or activates a live recursion creature, advances Urza's Saga, finds a relevant singleton, or prevents an imminent loss.

## Role Package
- Threats: Urza's Saga is the cleanest independent threat because it can pressure without relying on a creature staying alive and can find cheap artifacts if the rules engine exposes that chapter action. Emry, Lurker of the Loch, Goblin Welder, and Goblin Engineer also become threats when they survive because each threatens repeated artifact access rather than one combat step. Tezzeret, Cruel Captain is a singleton main-deck top-end threat or payoff; Card text check required before using it as a specific kill, draw engine, or artifact conversion plan.

- Payoffs: Ensnaring Bridge is the primary main-deck defensive payoff when the opponent's visible combat damage is the immediate problem, especially if the deck can deploy hand contents quickly. Legion Extruder, Phyrexian Dragon Engine, Agatha's Soul Cauldron, Skateboard, Pinnacle Emissary, and Sewer-veillance Cam are artifact payoffs or engine pieces only to the extent their visible text and legal actions support that role; Card text check required for exact activation, trigger, and target choices. Urza's Saga bodies are payoff pressure for simply accumulating artifacts.

- Engines: Emry, Lurker of the Loch is the blue recursion engine and should be protected by sequencing when possible, especially with Mishra's Bauble, Urza's Bauble, Chromatic Star, Lotus Petal, and other cheap artifacts available. Goblin Welder is the red battlefield-graveyard exchange engine and wants valuable artifacts in both zones before committing fragile exchanges. Goblin Engineer is both setup and access, often more important for placing or finding the correct singleton than for attacking.

- Velocity: Mishra's Bauble, Urza's Bauble, Chromatic Star, Lotus Petal, Mox Opal, fetchlands, and cheap artifacts make the deck function. Use velocity to turn on Mox Opal, reduce or enable Emry, Lurker of the Loch lines if legal, stock the graveyard for recursion, and keep Ensnaring Bridge functional when defense matters. Avoid spending Lotus Petal or sacrificing Chromatic Star casually if the visible hand needs the color or artifact count later in the same turn.

- Interaction: Main-deck interaction is narrow and mostly structural. Ensnaring Bridge fights combat, while Goblin Welder and Goblin Engineer can interact indirectly with artifacts if legal targets exist. Sideboard interaction is modular: Swan Song and Flusterstorm for stack fights, Disruptor Flute and Pithing Needle for named or activated constraints, Tormod's Crypt and Containment Priest for graveyard or entry-based plans, Portable Hole and Haywire Mite for permanents, Sudden Demise for creature boards, and Void Mirror for spell-construction pressure.

- Protection: Protect engines by sequencing redundant cheap artifacts first, holding fast mana when it enables a same-turn activation, and forcing opponents to answer Urza's Saga or recurring artifacts instead of one exposed creature. After sideboard, Swan Song and Flusterstorm protect key turns against visible stack interaction; Disruptor Flute, Pithing Needle, and Void Mirror can also protect by restricting opposing action patterns when the named or affected card is known or strategically justified.

- Recursion: Emry, Lurker of the Loch, Goblin Welder, and Goblin Engineer are the deck's graveyard core. Treat the graveyard as a second hand only when the engine exposes legal access to it; do not assume an artifact can be cast, exchanged, or returned unless Veles lists that action. Prioritize recurring artifacts that restore mana, generate cards, stabilize combat, or convert into a winning board.

- Mana: Volcanic Island, Great Furnace, Seat of the Synod, Mountain, Plateau, Scalding Tarn, Bloodstained Mire, Wooded Foothills, Urza's Saga, Mox Opal, Lotus Petal, and Chromatic Star define the mana puzzle. Blue supports Emry, Lurker of the Loch, red supports Goblin Welder and Goblin Engineer, white is mostly for sideboard cards, and artifact count often matters as much as color.

- Sideboard modules: Bring the sideboard in as role packages rather than generic upgrades. Use counter magic for spell-combo or stack-heavy opponents, graveyard tools for visible graveyard dependence, permanent answers for resolved hate or creature pressure, naming effects for known key cards, and the second Tezzeret, Cruel Captain when a slower matchup rewards another durable payoff.

## Primary Win Conditions
- Urza's Saga pressure is the cleanest main win path when the opponent is not already presenting a faster kill. Setup by developing cheap artifacts such as Mox Opal, Lotus Petal, Mishra's Bauble, Urza's Bauble, Chromatic Star, Great Furnace, Seat of the Synod, Sewer-veillance Cam, Skateboard, Agatha's Soul Cauldron, Legion Extruder, or Phyrexian Dragon Engine so the Saga-created bodies are meaningful. Execute by preserving artifact count, using the chapter ability when Veles exposes it, and attacking only when the visible board permits safe pressure. Disruption to respect includes Wasteland-style land pressure in prose, removal for artifact creatures, and sweepers; prioritize this path when Urza's Saga is already ticking, creature engines are not safe, or the hand can empty under Ensnaring Bridge while still making non-hand-based pressure.

- Emry, Lurker of the Loch recursion wins by turning cheap artifacts into repeated cards, mana, and battlefield material. Setup requires artifacts in the graveyard and enough blue or artifact-enabled mana to deploy Emry, Lurker of the Loch without sacrificing a crucial same-turn action. Execute by choosing legal graveyard artifact actions that increase resources first, then convert that advantage into Urza's Saga pressure, Phyrexian Dragon Engine pressure, or singleton payoffs. Disruption to respect includes graveyard hate, creature removal, and stack interaction on the first engine turn; prioritize this path when Mishra's Bauble, Urza's Bauble, Chromatic Star, Lotus Petal, or other castable artifacts are visible in the graveyard and the opponent is not forcing immediate Ensnaring Bridge defense.

- Goblin Welder plus Goblin Engineer is the red artifact-exchange win path when a useful artifact is in the graveyard and a disposable artifact is on the battlefield. Setup with Goblin Engineer placing or finding the correct artifact, cheap artifacts providing exchange fodder, and Great Furnace or other artifact permanents increasing flexibility. Execute only through listed legal actions: exchange, return, sacrifice, or target exactly what the engine offers, preferring lines that create a durable payoff, rebuy Phyrexian Dragon Engine, restore Ensnaring Bridge, or recycle value artifacts. Disruption to respect includes instant removal before activation, graveyard exile, and artifact removal in response; prioritize this path when a live Goblin Welder or Goblin Engineer can act before the opponent untaps or when the graveyard already contains the artifact that stabilizes or ends the game.

- Singleton artifact/payoff kills are conditional until card text is confirmed. Card text check required for Pinnacle Emissary, Sewer-veillance Cam, Skateboard, Legion Extruder, Agatha's Soul Cauldron, and Tezzeret, Cruel Captain. Treat visible legal actions from these cards as potential payoff lines, but do not assume a deterministic combo, damage loop, draw loop, or activated-ability transfer unless Veles exposes the specific action and targets.

## Secondary Win Conditions
- Ensnaring Bridge can create the time needed for small artifact engines to win without racing. Use it as a lock path when the opponent's visible creatures are the primary danger and the hand can be reduced quickly with Mox Opal, Lotus Petal, baubles, cheap artifacts, and land drops. Pressure then comes from Urza's Saga, recursive artifact value, Tezzeret, Cruel Captain if its visible actions support a payoff, or incremental creature attacks when Bridge no longer blocks your own relevant attacks.

- Phyrexian Dragon Engine is a backup creature and graveyard artifact payoff. Use it as pressure when attacking is legal and favorable, or as a recursion target when Goblin Welder, Goblin Engineer, or Emry, Lurker of the Loch can legally access it. Do not force this line through graveyard hate or open removal if Urza's Saga or Ensnaring Bridge is the safer visible plan.

- Goblin Welder, Goblin Engineer, Emry, Lurker of the Loch, Pinnacle Emissary, and artifact tokens can win by ordinary combat when the opponent stumbles. Attack when combat math is favorable, when preserving a tapped engine is unnecessary, or when the opponent is under a short clock. Hold back engine creatures when their activated or future value is worth more than a small attack.

- Tezzeret, Cruel Captain is a secondary top-end plan, especially in grindy games where a single permanent can create repeated value. Card text check required before treating it as removal, card advantage, animation, or lethal. Prioritize it when the opponent has spent resources answering creatures and graveyard engines, and deprioritize it when tapping out loses to a visible stack, combat, or combo threat.

## Emergency Lines
- When behind on life or board, stabilize before maximizing value. Prioritize Ensnaring Bridge, Sudden Demise after sideboard, Portable Hole after sideboard, Haywire Mite after sideboard, or any legal Goblin Welder/Goblin Engineer line that removes or neutralizes the most urgent visible threat. Use Lotus Petal and Mox Opal aggressively if they enable the stabilizing action this turn.

- When behind on cards, convert graveyard and bauble resources into repeated decisions rather than spending the last card on low-impact pressure. Emry, Lurker of the Loch with Mishra's Bauble, Urza's Bauble, or Chromatic Star is the preferred recovery pattern when legal. Goblin Engineer should find or stock the artifact that answers the current failure point instead of the flashiest payoff.

- When behind on mana, preserve artifact count for Mox Opal and avoid sacrificing Lotus Petal or Chromatic Star unless the current action changes the game state materially. Use Urza's Saga carefully because it is both mana development and a delayed threat; do not expose it to unnecessary loss if another land covers the turn.

- When graveyard recursion is shut off, pivot to battlefield pressure and hand-based deployment. Urza's Saga, Mox Opal-enabled starts, hard-cast artifacts, and Tezzeret, Cruel Captain become more important, while Goblin Welder, Goblin Engineer, and Emry, Lurker of the Loch should be used only for visible legal value rather than assumed recursion plans.

- When primary win conditions are removed, win by sequencing whatever visible artifacts still compound. Small attacks, Ensnaring Bridge time, Urza's Saga if drawn later, Phyrexian Dragon Engine combat, and sideboard interaction can still produce a game. Do not concede or take speculative hidden-information lines; choose the legal action that preserves outs, reduces the opponent's clock, or rebuilds an artifact engine.

## Resource Model
- Life is a tempo buffer, not a resource to spend freely. Use life to absorb early damage only when the gained turn deploys Emry, Lurker of the Loch, Goblin Engineer, Goblin Welder, Ensnaring Bridge, Urza's Saga pressure, or a sideboard answer; stabilize immediately when visible attacks threaten to shorten the game below the engine's setup window.

- Hand size is both fuel and liability. Empty cheap artifacts, Lotus Petal, Mox Opal, Mishra's Bauble, Urza's Bauble, and Chromatic Star quickly when Ensnaring Bridge matters, but preserve at least one meaningful follow-up when the opponent is trading one-for-one and the board is stable.

- Mana is explosive but fragile. Mox Opal and Lotus Petal convert artifact density into early engine turns, while Volcanic Island, Great Furnace, Plateau, Mountain, and Seat of the Synod anchor repeatable colors. Treat Lotus Petal as acceleration for a decisive turn, color fixing for Emry, Lurker of the Loch or red engine creatures, or emergency interaction after sideboard.

- Board presence is mostly engine infrastructure. Goblin Welder, Goblin Engineer, Emry, Lurker of the Loch, Urza's Saga, Great Furnace, Mox Opal, and cheap artifacts should be valued by how they enable repeated legal actions, not by raw size. Attack with small creatures only when the engine body is not needed for an activation, block, or future recursion line.

- Graveyard resources are live only when the rules engine exposes legal recursion or exchange actions. Stock the graveyard with Mishra's Bauble, Urza's Bauble, Chromatic Star, Lotus Petal, Phyrexian Dragon Engine, Ensnaring Bridge, or other artifacts when Goblin Engineer, Goblin Welder, or Emry, Lurker of the Loch can convert them; pivot away if Tormod's Crypt-like exile effects or visible graveyard hate are present.

- Exile is usually a lost-resource zone unless a visible card or effect says otherwise. Do not assume recovered artifacts, recast permissions, or Agatha's Soul Cauldron lines without legal actions from Veles. Card text check required for Agatha's Soul Cauldron, Pinnacle Emissary, Sewer-veillance Cam, Skateboard, Legion Extruder, and Tezzeret, Cruel Captain.

- Lands are split between colored stability and artifact utility. Urza's Saga is a land, threat, artifact tutor, and clock, so sequence it early when the hand can operate through its delayed sacrifice, and delay it when colored mana is required for Emry, Lurker of the Loch, Goblin Welder, or Goblin Engineer first.

- Sacrifice fodder is a premium resource. Mishra's Bauble, Urza's Bauble, Lotus Petal after it has served its mana purpose, Chromatic Star when mana/card conversion is legal, Great Furnace, and expendable tokens can support Goblin Welder, Goblin Engineer, Legion Extruder, or other visible sacrifice actions. Do not sacrifice the only artifact keeping Mox Opal active unless the resulting action is decisive.

- Information is generated by baubles and public actions. Use Mishra's Bauble and Urza's Bauble information to time fetch lands, decide whether to commit Ensnaring Bridge, and choose whether to hold interaction after sideboard. Respect only visible or legally revealed cards; never infer exact hidden hands beyond archetype-level pressure.

- Sideboard bullets convert narrow mana and timing windows into matchup leverage. Swan Song and Flusterstorm tax stack timing, Void Mirror and Disruptor Flute constrain opposing plans, Pithing Needle names visible or known activated problems, Tormod's Crypt and Containment Priest pressure graveyards, Haywire Mite and Portable Hole answer permanents, Sudden Demise stabilizes creature boards, and the sideboard Tezzeret, Cruel Captain increases grind potential when card text and legality support it.

## Mana Guide
- Prioritize functional color plus artifact count over raw land count. Keep hands that produce blue for Emry, Lurker of the Loch or red for Goblin Welder/Goblin Engineer while also enabling Mox Opal, Urza's Saga, or cheap artifact deployment; mulligan hands that rely on a single Lotus Petal for all colored mana without a decisive first-turn engine.

- Sequence artifact lands with Mox Opal in mind. Great Furnace and Seat of the Synod increase metalcraft while producing colored mana, so they are strong early plays when artifact removal risk is acceptable. Preserve Seat of the Synod when blue is scarce, and preserve Great Furnace when red activations or sideboard red spells matter.

- Use fetch lands to solve colors before speculative thinning. Scalding Tarn, Bloodstained Mire, and Wooded Foothills should find the color the current hand actually needs, usually Volcanic Island for blue-red starts, Plateau when white sideboard cards or splashes are needed, or Mountain when red is enough and nonbasic exposure matters.

- Deploy Urza's Saga when the hand can spend the next turns productively. Early Urza's Saga is excellent with cheap artifacts and Mox Opal, but it does not cast Emry, Lurker of the Loch or red creatures by itself after it sacrifices. If the only colored source is missing, play a colored land first unless Urza's Saga is the visible winning line.

- Spend Lotus Petal for commitment turns, not cosmetic speed. Use it to cast Emry, Lurker of the Loch early, enable Goblin Engineer or Goblin Welder plus another artifact, hold up Swan Song or Flusterstorm after sideboard, or pay for a visible decisive action. Avoid cracking it merely to empty the hand unless Ensnaring Bridge survival depends on that card leaving hand.

- Maintain Mox Opal metalcraft before choosing optional sacrifices. Count Great Furnace, Seat of the Synod, baubles, Lotus Petal, artifacts from Urza's Saga, and other cheap artifacts before tapping or sacrificing. If losing metalcraft strands a legal action, prefer a different payment source when Veles offers one.

- Play lands before draw effects when mana certainty is required this turn. If the current legal line needs a land drop to cast Goblin Engineer, Emry, Lurker of the Loch, Ensnaring Bridge, Sudden Demise, Portable Hole, or protection, make the land drop first. Delay the land drop when Mishra's Bauble or Urza's Bauble information, Chromatic Star draw timing, or a fetch-land decision can materially change which land should be used.

- Keep one-land hands only with concrete acceleration and action. A keepable one-land hand should normally include Lotus Petal or Mox Opal plus multiple cheap artifacts and a live engine card such as Emry, Lurker of the Loch, Goblin Engineer, Goblin Welder, or Urza's Saga. One-land hands with only expensive or card-text-uncertain payoffs should be treated as unstable.

- Sideboard mana changes the value of white and reactive blue. Portable Hole and Containment Priest increase the need for Plateau or Lotus Petal white access, while Swan Song and Flusterstorm reward Volcanic Island, Seat of the Synod plus Mox Opal, or Lotus Petal held open. Sudden Demise increases the value of reliable red and careful generic-mana planning.

## Mulligan Guide
- Strong keeps start with colored mana, cheap artifacts, and a live engine. Keep Volcanic Island or Seat of the Synod plus Mox Opal, Mishra's Bauble or Urza's Bauble, Lotus Petal, and Emry, Lurker of the Loch; keep Volcanic Island or Great Furnace plus Goblin Engineer, Goblin Welder, and at least one expendable artifact if the hand can act through the first two turns.

- Medium keeps have one engine axis and one stabilizer but imperfect mana. Keep Urza's Saga plus Mox Opal, Lotus Petal, Mishra's Bauble, and Goblin Engineer or Emry, Lurker of the Loch when metalcraft is plausible; keep Great Furnace plus Goblin Welder and multiple baubles when the hand can create graveyard material before activating.

- Risky keeps need a clear payoff before accepting fragility. One-land hands with Lotus Petal, Mox Opal, and multiple cheap artifacts are acceptable only if they cast Emry, Lurker of the Loch, Goblin Engineer, or early Urza's Saga pressure; hands relying on Lotus Petal as the only colored source should be kept only on a fast, visible engine start.

- Automatic ships lack mana, lack action, or contain stranded singletons. Mulligan no-land hands, hands with only Urza's Saga and no Mox Opal or Lotus Petal support, hands with Ensnaring Bridge plus expensive or card-text-uncertain cards but no way to empty hand, and hands whose first real play is only Tezzeret, Cruel Captain without reliable mana.

- Matchup-dependent keeps change after sideboard. Against fast spell combo, a slower hand becomes keepable with Swan Song, Flusterstorm, Void Mirror, or Disruptor Flute plus mana; against graveyard plans, Tormod's Crypt or Containment Priest can justify a lower-pressure hand; against creature pressure, Portable Hole, Sudden Demise, Ensnaring Bridge, or fast Urza's Saga matters more than speculative bauble velocity.

- Play/draw changes tolerance for setup. On the play, prioritize a turn-one engine body, Urza's Saga, or protected metalcraft because tempo is the deck's shield; on the draw, accept slightly slower hands with more cards, baubles, and interaction, but punish hands that fold to one opposing disruptive action before the first engine activation.

- Trap hands look explosive but do nothing after the first exchange. Do not keep Mox Opal plus artifacts if metalcraft disappears after sacrificing Lotus Petal or baubles; do not keep Goblin Welder without an artifact to exchange or a way to put one into the graveyard; do not keep Pinnacle Emissary, Sewer-veillance Cam, Skateboard, Legion Extruder, Agatha's Soul Cauldron, or Tezzeret, Cruel Captain as the reason alone unless Veles exposes their relevant legal actions. Card text check required for those cards.

- Mulligan bottoming should preserve mana plus the first engine. Bottom redundant legendary Emry, Lurker of the Loch before the only red source, bottom late singletons before Mox Opal support, and bottom excess lands only when Urza's Saga or baubles keep the hand functional.

## Turn Arc
- Turn 1 should establish mana infrastructure or the first engine. Preferred starts are Volcanic Island or Seat of the Synod into cheap artifacts plus Emry, Lurker of the Loch when legal; Great Furnace into Goblin Welder with Mishra's Bauble, Urza's Bauble, Lotus Petal, or Chromatic Star available; or Urza's Saga when the hand can operate without immediate colored land.

- Turn 1 deviations protect the hand from collapse. Play a colored land before Urza's Saga when Emry, Lurker of the Loch, Goblin Engineer, or Goblin Welder must be cast on schedule; hold Lotus Petal if it is needed for turn-two mana or post-board Swan Song or Flusterstorm; use baubles before a fetch only when their visible information changes the fetch decision.

- Turn 2 should convert setup into recursion, tutoring, or pressure. Cast Goblin Engineer to put the artifact that the visible line needs into the graveyard, activate Goblin Welder only when the exchange improves board or unlocks a decisive artifact, and use Emry, Lurker of the Loch recast permissions only for legal artifacts that advance mana, cards, or protection.

- Turn 2 deviations respect open interaction and graveyard hate. If the opponent represents removal, prioritize redundant engines over a single all-in exchange; if visible graveyard hate threatens Emry, Lurker of the Loch or Goblin Welder lines, lean on Urza's Saga, Mox Opal mana, and hard-cast artifacts instead of stocking the graveyard blindly.

- Turn 3 is the first commitment checkpoint. Start a major Goblin Engineer/Goblin Welder chain, Urza's Saga tutor turn, Ensnaring Bridge defense, Legion Extruder line, Agatha's Soul Cauldron line, or Tezzeret, Cruel Captain line only when legal actions and visible board state support it; otherwise keep developing cheap artifacts, mana, and redundant engines. Card text check required for Legion Extruder, Agatha's Soul Cauldron, and Tezzeret, Cruel Captain.

- Turns 4-5 should decide whether the game is a bridge, saga, or recursion game. Use Ensnaring Bridge when creature pressure makes hand-size management relevant, use Urza's Saga tokens and tutor action to close or stabilize, and loop Mishra's Bauble, Urza's Bauble, Chromatic Star, Lotus Petal, Phyrexian Dragon Engine, or other legal artifacts only when the rules engine shows the recursion path.

- Late game should trade expendable artifacts for inevitability while preserving the final engine. Keep at least one active route through Emry, Lurker of the Loch, Goblin Welder, Goblin Engineer, Urza's Saga constructs, or Tezzeret, Cruel Captain; avoid spending the last artifact, last colored source, or last metalcraft piece unless the visible action wins, prevents lethal, or locks the opponent out of profitable attacks.

## Card Roles
- Emry, Lurker of the Loch is the blue engine that turns cheap artifacts into repeated material. Cast Emry, Lurker of the Loch early when the hand has at least one recastable artifact, but avoid exposing the only engine into obvious removal if Goblin Engineer or Goblin Welder can diversify first. Use Emry, Lurker of the Loch to replay Mishra's Bauble, Urza's Bauble, Chromatic Star, Lotus Petal, Mox Opal, or a legal artifact payoff only when Veles shows the cast action; do not assume graveyard artifacts are castable through hate, timing limits, or cost restrictions. In slower matchups, Emry, Lurker of the Loch rewards patience because one untap can create multiple looks, mana, or sacrifice fodder; against fast combo, she matters mainly if she finds or supports a disruptive artifact line quickly.

- Goblin Welder is the highest-leverage red engine and should be treated as a fragile commitment piece. Cast Goblin Welder when there is already a cheap artifact in play or a meaningful artifact in the graveyard, and delay activation until the exact exchange improves the visible board, protects from pressure, recovers a destroyed engine, or converts a bauble into a stronger artifact. Do not activate Goblin Welder just because it is legal; each exchange changes both battlefield and graveyard resources. Against removal-heavy decks, lead with redundant artifacts before exposing the exchange target. Against graveyard hate, use Goblin Welder only after checking whether the target remains visible and legal.

- Goblin Engineer is the bridge between tutoring, graveyard setup, and artifact recursion. Cast Goblin Engineer when the hand needs a specific artifact role, such as Ensnaring Bridge for defense, Phyrexian Dragon Engine for card or pressure lines, Agatha's Soul Cauldron for engine text if legal, Legion Extruder or Skateboard if their text is relevant, or a cheap artifact to enable Goblin Welder. Card text check required for Legion Extruder and Skateboard. Do not tutor a singleton into the graveyard without a plan to use it; Goblin Engineer is best when the next one or two decisions are already supported by visible mana, Goblin Welder, Emry, Lurker of the Loch, or its own legal activated ability.

- Mox Opal is both acceleration and a metalcraft dependency. Play Mox Opal early when it turns on Emry, Lurker of the Loch, Goblin Engineer, Goblin Welder plus another artifact, Swan Song or Flusterstorm after sideboard, or a key Urza's Saga turn. Hold redundant Mox Opal when legend-rule pressure would waste an artifact count or when a later metalcraft trigger matters more. Do not sacrifice Lotus Petal or baubles in a way that unexpectedly turns off Mox Opal unless the resulting action is decisive or required for survival.

- Lotus Petal is tempo, color fixing, and a one-shot artifact count. Spend Lotus Petal to land a first engine, protect a post-board turn with Swan Song or Flusterstorm, cast Tezzeret, Cruel Captain ahead of schedule if legal, or enable a decisive Goblin Engineer/Goblin Welder chain. Hold Lotus Petal when it is the only future white source for Portable Hole or Containment Priest after sideboard, or when using it would remove metalcraft before Mox Opal produces mana.

- Mishra's Bauble is free artifact density, graveyard fuel, and Emry, Lurker of the Loch material. Deploy Mishra's Bauble to enable Mox Opal, reduce Emry, Lurker of the Loch cost, stock Goblin Welder exchanges, or provide a free recast. Use its look information before fetchland decisions when Veles exposes the action and the top-card knowledge matters. Avoid cashing it in if the artifact body is needed for metalcraft, Urza's Saga construct size, or a visible Goblin Welder exchange.

- Urza's Bauble fills the same structural role as Mishra's Bauble but can affect hidden-information planning differently if the rules engine exposes its legal look action. Use Urza's Bauble as a zero-mana artifact for Mox Opal, Emry, Lurker of the Loch, Goblin Welder, and Urza's Saga sizing. Do not infer exact hidden cards unless the Veles state shows them; if the card only reveals at a delayed or limited window, treat that information according to the visible-state output.

- Chromatic Star is the cleanest single-card color fixer and exchange fodder. Use Chromatic Star when the hand needs a specific color for Emry, Lurker of the Loch, Goblin Engineer, Goblin Welder, sideboard interaction, or a singleton payoff. It is often better than a bauble as Goblin Welder fodder when the visible line needs both a graveyard artifact and a card replacement. Do not spend Chromatic Star just to cycle if colored mana will be needed later in the same turn.

- Urza's Saga is a land, threat, artifact tutor, and clock all at once. Play Urza's Saga early when the hand can still cast colored spells, and prioritize construct creation when the board needs pressure or blockers. On the tutor chapter, search for the artifact that solves the current problem from visible legal options: Mox Opal for mana, Mishra's Bauble or Urza's Bauble for cheap engine material, Chromatic Star for color, Tormod's Crypt after sideboard for graveyard pressure if available, or Pithing Needle after sideboard when a visible activated ability must be named. Do not keep hands where Urza's Saga is the only mana plan unless Mox Opal, Lotus Petal, or cheap artifacts make the first turns functional.

- Ensnaring Bridge is the emergency stabilizer and should be paired with hand-size discipline. Cast Ensnaring Bridge when opposing creature pressure threatens lethal or forces bad trades, then prioritize playing out cheap artifacts and lands so the bridge text remains relevant. Do not assume Ensnaring Bridge stops every attacker; follow Veles combat legality and card-specific exceptions. Against creature-light combo, Ensnaring Bridge is lower priority unless it protects Tezzeret, Cruel Captain or buys turns against a visible battlefield.

- Phyrexian Dragon Engine is a singleton artifact payoff and recursion target. Card text is familiar but still verify legal actions at runtime: use Phyrexian Dragon Engine when Veles exposes cast, activate, or graveyard-related actions that convert it into cards, pressure, or a Goblin Welder target. Do not strand it in hand if Goblin Engineer can place it where the current engine wants it, but do not tutor it over defense or interaction when under immediate pressure.

- Agatha's Soul Cauldron is a singleton engine artifact with graveyard and ability implications. Card text check required for exact runtime behavior in this shell. Treat Agatha's Soul Cauldron as a commitment card: deploy it when there are meaningful creatures or activated abilities in graveyards and the legal actions show it advances the board. Avoid spending tutor or mana resources on it when no relevant graveyard text, counter interaction, or activated-ability payoff is visible.

- Legion Extruder is a singleton artifact or artifact-adjacent payoff that requires exact text validation. Card text check required. Use Legion Extruder only when Veles exposes legal actions whose labels clearly advance a known plan, such as producing pressure, converting expendable artifacts, or stabilizing. Do not select Legion Extruder as a Goblin Engineer target by default; it needs a visible tactical purpose over Ensnaring Bridge, Phyrexian Dragon Engine, Mox Opal, Chromatic Star, or other confirmed artifacts.

- Pinnacle Emissary is a four-copy main-deck role-player and must be evaluated from visible legal actions because its exact text is uncertain here. Card text check required. Keep or cast Pinnacle Emissary only when its legal actions support the active role: engine setup, artifact count, pressure, mana, or stabilization. Because it has four copies, it can be used as a redundant body or resource more freely than the singletons, but do not let copy count justify low-impact sequencing under a short clock.

- Sewer-veillance Cam is a four-copy artifact-looking engine piece and needs runtime text confirmation. Card text check required. Treat Sewer-veillance Cam as important cheap infrastructure when it enables Mox Opal, Emry, Lurker of the Loch, Goblin Welder, Goblin Engineer, or Urza's Saga constructs. If Veles shows selection, surveillance, graveyard, token, or sacrifice-related actions, choose them only when they improve the current visible plan; do not assume it surveils, draws, mills, or targets without the engine output.

- Skateboard is a singleton and should not drive mulligans by itself. Card text check required. Use Skateboard as a tutor or recursion target only when the legal action text makes its role explicit for pressure, mobility, mana, protection, or artifact conversion. If its purpose is unclear, prefer known engine pieces and defensive artifacts.

- Tezzeret, Cruel Captain is a singleton main-deck top-end card and a second sideboard copy can increase grind density. Card text check required. Cast Tezzeret, Cruel Captain when mana is stable and the visible board can protect it or immediately profit from its legal action. Do not tap out for Tezzeret, Cruel Captain against fast combo or lethal pressure unless the exposed action stabilizes, finds interaction, or wins soon.

- Volcanic Island, Great Furnace, Seat of the Synod, Mountain, Plateau, Scalding Tarn, Bloodstained Mire, and Wooded Foothills define color access and artifact density. Prioritize Volcanic Island for blue-red engine starts, Great Furnace and Seat of the Synod for artifact count and Goblin Welder/Mox Opal synergy, Mountain for stable red through nonbasic pressure, and Plateau only when white sideboard cards or red-white access matter. Use fetchlands to fix current and next-turn colors, not just to thin the deck; bauble information can change the fetch decision only when Veles shows the relevant top-card information.

## Interaction Priorities

- Priority: Protect Goblin Welder, Goblin Engineer, and Emry, Lurker of the Loch when they are converting graveyard artifacts into material advantage or enabling a committed combo line. Force the opponent to answer redundant cheap artifacts first when possible, and do not expose the last engine creature into visible removal, stack pressure, or combat unless the legal action immediately recovers value.

- Priority: Use Swan Song and Flusterstorm after sideboard on the opponent action that stops the engine, wins the game, or removes the only stabilizer. Counter graveyard hate, artifact sweepers, fast combo payoffs, and interaction aimed at a live Goblin Welder, Goblin Engineer, Emry, Lurker of the Loch, Urza's Saga, Ensnaring Bridge, or Tezzeret, Cruel Captain before countering cantrips, setup, or low-impact pressure.

- Priority: Use Portable Hole, Haywire Mite, Pithing Needle, Disruptor Flute, Tormod's Crypt, Void Mirror, Containment Priest, and Sudden Demise according to the visible threat, not as generic interaction. Portable Hole and Haywire Mite should answer a permanent that blocks the current engine, attacks through the stabilizing plan, or shuts off artifacts; Pithing Needle and Disruptor Flute should name or constrain a visible activated ability or spell pattern only when Veles exposes enough public information to make the choice legal and grounded.

- Priority: Remove or contain hate pieces before protecting marginal value. If an opponent permanent disables artifacts, graveyard recursion, activated abilities, searching, or combat stabilization, prioritize answering it over advancing Pinnacle Emissary, Sewer-veillance Cam, Skateboard, Legion Extruder, or Tezzeret, Cruel Captain unless the exposed legal action wins or stabilizes immediately. Card text check required for Pinnacle Emissary, Sewer-veillance Cam, Skateboard, Legion Extruder, and Tezzeret, Cruel Captain before treating them as interaction.

- Bait: Lead with Mishra's Bauble, Urza's Bauble, Chromatic Star, Lotus Petal, Mox Opal, or an Urza's Saga construct when the hand has redundant material and the opponent is likely to spend interaction inefficiently. Do not bait with the only Goblin Welder, only Goblin Engineer, only Emry, Lurker of the Loch, only Ensnaring Bridge, or only colored mana source unless waiting gives the opponent a better window.

- Ignore: Ignore small nonlethal attackers, low-impact card selection, and resources that do not change the visible clock when an engine line is online. Against combo or prison-style opponents, ignore creature combat unless it threatens the next turn cycle; against creature decks, ignore nonlethal setup only if Ensnaring Bridge, Sudden Demise, Urza's Saga constructs, or a recursion line visibly covers the board.

- Discard and bounce: This registered list has no main-deck discard or bounce card by name, so never choose a discard or bounce plan unless the rules engine exposes that exact legal action from a registered card. If a sideboard or copied ability creates an exile, destroy, counter, or prevention action, choose from the legal action text and visible board only.

## Combat And Trading Rules

- Priority: Treat combat as a way to buy engine time unless Urza's Saga constructs or artifact payoffs create a clear clock. Attack when the available attackers survive profitably, pressure a vulnerable opponent, or force blocks that make Goblin Welder, Goblin Engineer, Emry, Lurker of the Loch, or artifact recursion stronger; hold back when blocking preserves life total for a longer engine game.

- Priority: Preserve engine creatures over chip damage. Do not attack Goblin Welder, Goblin Engineer, or Emry, Lurker of the Loch into visible blockers when their next activation, cast, or graveyard access is more valuable than the damage. Trade them only when the opponent creature is the visible path to lethal, prevents Ensnaring Bridge from stabilizing, or the graveyard and hand already contain redundant replacement engines.

- Priority: Use Urza's Saga constructs as flexible pressure and defense. Attack with constructs when their artifact count makes blocks bad for the opponent or when the opponent is under a short clock; keep them back when they are the only meaningful blockers protecting Tezzeret, Cruel Captain, life total, or a turn needed for Ensnaring Bridge. Remember that sacrificing or spending cheap artifacts can shrink constructs, so sequence combat before artifact conversion when size matters.

- Priority: Ensnaring Bridge changes combat from trading to hand-size management. Once Ensnaring Bridge is on board, prefer playing out Lotus Petal, Mox Opal, Mishra's Bauble, Urza's Bauble, Chromatic Star, Great Furnace, Seat of the Synod, and other cheap artifacts if lowering hand size restricts attacks. Do not assume Ensnaring Bridge prevents every combat line; follow Veles attack and block legality.

- Threshold: Protect life total aggressively against fast creature decks once the visible next attack plus likely follow-up damage threatens the next two turns. Block with constructs, expendable artifact creatures, or redundant bodies before spending a critical engine creature, and use Sudden Demise after sideboard when it removes enough visible pressure to change the race.

- Archetype shift: Race slower control and combo opponents with Urza's Saga constructs, recursive artifact pressure, and Tezzeret, Cruel Captain when interaction is covered. Stabilize first against aggressive creature decks, preserve Ensnaring Bridge lines, and avoid attacks that leave too few blockers. Against graveyard or artifact-hate decks, keep combat conservative until the hate piece is answered or the engine can win through it.

## Selection And Tutor Rules

- Priority: Use Goblin Engineer as the main deterministic tutor because it converts the library into a graveyard target for Goblin Welder, Emry, Lurker of the Loch, or later artifact recursion. Find Ensnaring Bridge when combat is the visible problem, Phyrexian Dragon Engine when a pressure or card-flow engine is needed, Agatha's Soul Cauldron when a graveyard or ability line is clearly supported, and a cheap artifact only when metalcraft, sacrifice material, or immediate Goblin Welder exchange matters more than a unique artifact.

- Priority: Use Urza's Saga chapter III as a live-board tutor, not a generic value trigger. In game one, default candidates are Mox Opal, Lotus Petal, Mishra's Bauble, Urza's Bauble, and Chromatic Star; choose mana when the current or next legal action needs it, choose a bauble when information or artifact count matters, and choose Chromatic Star when color fixing plus artifact material is more important than raw speed. After sideboard, Tormod's Crypt, Pithing Needle, Haywire Mite, and Portable Hole become valid targets if they are boarded in and Veles shows the legal tutor action.

- Priority: Sequence Mishra's Bauble and Urza's Bauble around fetchlands and Emry, Lurker of the Loch. If a bauble can reveal or inform the top card before a Scalding Tarn, Bloodstained Mire, or Wooded Foothills decision, use that information before fetching unless the mana is needed immediately; if Emry, Lurker of the Loch can reuse a bauble, preserve the loop over one-shot cycling when hand size, metalcraft, or artifact count already meets the current need.

- Priority: Treat Chromatic Star as fixing, artifact count, and graveyard material before treating it as a random redraw. Spend it when it unlocks Emry, Lurker of the Loch, Goblin Engineer, Goblin Welder, Tezzeret, Cruel Captain, Portable Hole, Containment Priest, or sideboard interaction, or when putting it into the graveyard improves a visible recursion line.

- Priority: Use Goblin Welder selection only after comparing both sides of the exchange. Trade a low-impact artifact such as a spent bauble, Lotus Petal, Chromatic Star, or disposable construct material for Ensnaring Bridge, Phyrexian Dragon Engine, Agatha's Soul Cauldron, Legion Extruder, Skateboard, Sewer-veillance Cam, or another visible high-impact artifact only when the destination artifact changes the board immediately or survives known interaction. Card text check required for Legion Extruder, Skateboard, Sewer-veillance Cam, Pinnacle Emissary, and Tezzeret, Cruel Captain before assigning exact search or recursion priority.

- Land timing: Delay fetchlands when bauble information can change the target and no immediate colored mana is required. Play artifact lands such as Great Furnace and Seat of the Synod before nonartifact lands when Mox Opal, Urza's Saga construct size, Emry, Lurker of the Loch cost reduction, or artifact count matters; play Volcanic Island or Plateau first when colored sideboard interaction or Goblin Engineer access is the bottleneck.

## Priority And Stack Rules

- Priority: Take instant-speed windows seriously when Goblin Welder, Emry, Lurker of the Loch, baubles, Lotus Petal, Mox Opal, and sideboard counters create meaningful choices. Pass only when the visible legal actions do not improve mana, protect the engine, answer a hate piece, convert graveyard material, or change combat math.

- Priority: Activate Goblin Welder at the last safe moment when waiting preserves information or forces the opponent to commit. Use it before damage, before a removal spell resolves, or before graveyard hate resolves when the exchange protects a key artifact or converts a threatened permanent into value; do not activate into an opponent permanent or stack item that visibly makes the exchange illegal or poor.

- Priority: Use Emry, Lurker of the Loch recursion when the selected artifact advances the current turn cycle. Recast Mishra's Bauble, Urza's Bauble, Lotus Petal, Chromatic Star, Mox Opal, or a tutored sideboard artifact when the legal action supplies mana, information, metalcraft, graveyard churn, or interaction; wait when using the graveyard now exposes the only good target to visible exile or counterplay.

- Priority: Let opponent spells resolve when they do not affect the engine, the clock, or a protected permanent. Spend Swan Song, Flusterstorm, Void Mirror pressure, Disruptor Flute timing, or other sideboard interaction on spells that stop Goblin Welder, Goblin Engineer, Emry, Lurker of the Loch, Urza's Saga, Ensnaring Bridge, or a committed Tezzeret, Cruel Captain line, not on low-impact setup.

- Priority: Use bauble activations before hidden-information decisions only when the resulting public or private information can change a fetch, tutor, counter, or combat decision. If the only effect is delayed card replacement and no current decision depends on the information, preserve the bauble for artifact count, construct size, Goblin Welder material, or Emry, Lurker of the Loch reuse.

- Optional payments and triggers: Make optional payments only when they preserve the chosen line. Do not spend Lotus Petal, Mox Opal mana, Chromatic Star fixing, or artifact material on optional value if that mana or artifact is needed for Swan Song, Flusterstorm, Goblin Welder activation timing, Urza's Saga activation, Portable Hole, Haywire Mite, or a visible engine spell.

- Combat windows: Before attackers and blockers, use activated abilities only if the exchange changes legal attacks, blocks, construct size, Ensnaring Bridge hand size, or lethal math. After blockers and before damage, prioritize Goblin Welder or sacrifice-style actions that save a dying artifact creature, recur a stabilizer, or deny the opponent a favorable trade, while following only Veles-provided legal actions.

- Graveyard timing: Respect public graveyard hate and stack timing. If Tormod's Crypt, opposing exile effects, or visible graveyard interaction threaten the only recursion target, either use the target immediately through a legal action or shift to Urza's Saga constructs, hard-cast artifacts, Tezzeret, Cruel Captain, or Ensnaring Bridge stabilization until the hate is answered.

- Flusterstorm is for spell-density fights where the opponent’s decisive turn uses instants or sorceries and your own engine needs one cheap protection point. Bring it against storm-style combo, blue stack battles, Reanimator protection fights, and removal-heavy tempo when the key exchange is over Goblin Welder, Goblin Engineer, Emry, Lurker of the Loch, Urza's Saga, or a forced artifact engine action. It is weak when the opponent’s threats are mostly creatures, artifacts, lands, or activated abilities, and it should not be boarded merely because the opponent is blue if the visible games are decided by permanents.

- Swan Song is for broad noncreature protection and combo disruption when a single mana answer can stop a payoff, removal spell, sweeper, prison piece, or graveyard enabler. Bring it against spell combo, graveyard combo, artifact hate, planeswalker-adjacent support spells, and control decks that must resolve a high-impact noncreature spell to beat the engine. The Bird token matters against low-life or Ensnaring Bridge games, so do not spend Swan Song on a low-impact spell when the token creates a faster clock than the card being countered.

- Void Mirror is for zero-mana, alternate-mana, and colorless-pressure plans where the opponent’s early turn can invalidate normal engine development. Bring it when the opponent shows free spells, artifact mana chains, cascade-like pressure, or colorless spell sequences; use it as a lock piece that buys time for Urza's Saga, Goblin Engineer, and Goblin Welder rather than as a random hate artifact. It is weak when the opponent casts mostly colored spells using lands, and it can conflict with your own Lotus Petal, Mox Opal, and artifact-heavy starts if Veles shows your legal actions becoming constrained.

- Disruptor Flute is for named-card bottlenecks, activated ability pressure, or combo decks relying on a narrow engine piece. Bring it when the opponent repeatedly presents one card or one activated ability that must be slowed before your graveyard-artifact engine can work. Card text check required for exact naming, timing, and cost-tax implications; choose the name from visible public information, revealed cards, or repeated game actions, not from assumed hidden hand contents. It is weaker against wide fair decks where no single named card changes the matchup.

- Tormod's Crypt is the default graveyard hate because Urza's Saga can find it after sideboard and Emry, Lurker of the Loch can sometimes reuse artifact material around it. Bring it against Reanimator, graveyard combo, escape or dredge-style engines, and any deck where public graveyard count is a core resource. It is poor against fair decks using the graveyard only incidentally; preserve it on board until the opponent commits a graveyard-dependent legal action unless immediate use prevents lethal or a deterministic combo.

- Containment Priest is for creature-entry shortcuts and graveyard creature plans where a permanent hate piece changes the opponent’s legal route. Bring it against Reanimator, creature cheat effects, and creature-combo decks if white mana from Plateau, Lotus Petal, Mox Opal, or Chromatic Star is supportable. It is weaker when the opponent wins through noncreature spells or hard-cast threats, and it can stress the mana base more than Tormod's Crypt; prioritize it when its body or static text matters before the first graveyard activation resolves. Card text check required for exact interaction with each opponent effect.

- Pithing Needle is for visible activated abilities, lands, planeswalkers, equipment-like engines, and graveyard hate permanents that block Goblin Welder or Emry, Lurker of the Loch. Bring it when the opponent’s best card is a named permanent with an activated ability or when game one revealed a single permanent repeatedly deciding the game. It is weak against decks whose threats are triggered abilities, static abilities, or spell chains; name only from public information, revealed information, or battlefield context unless Veles surfaces an explicit strategic prompt.

- Haywire Mite is for artifacts and enchantments that stop recursion, construct combat, or engine permanents. Bring it against artifact prison, enchantment hate, graveyard hate artifacts, and permanent-heavy control where an Urza's Saga target that answers a hate piece is worth slowing down. It is bad when the opponent has few valid targets or when green mana cannot be produced reliably; Card text check required for exact activation cost, life gain, and exile wording before treating it as guaranteed removal.

- Portable Hole is for cheap permanents that block early development or create an immediate combat clock. Bring it against low-cost creatures, artifact hate pieces, and one- or two-mana permanents that prevent Goblin Welder, Goblin Engineer, Emry, Lurker of the Loch, or Urza's Saga from taking over. It is weaker against large threats, spell combo, and decks where white mana access delays the core engine; use it as a tempo bridge into constructs or recursion, not as the primary plan.

- Sudden Demise is for creature clusters where one color dominates the opposing battlefield and a sweeper resets pressure better than Ensnaring Bridge alone. Bring it against tribal, tempo, and small-creature decks that pressure life total while disrupting the engine. Card text check required for exact color choice, damage value, and targeting rules; choose the color from visible creatures only. It is weak against mixed-color boards, large creatures, spell combo, and matchups where spending red mana on a sweeper prevents a decisive Goblin Engineer or Goblin Welder turn.

- Tezzeret, Cruel Captain from the sideboard is for fair, removal-heavy, or attrition matchups where a second high-impact threat improves top-end density after the opponent reduces the value of small artifacts. Card text check required before assigning exact loyalty, artifact, or win-condition roles; treat the second copy as a resilient pressure or advantage slot only when mana and board texture support a longer game. It is weak against fast combo and heavy mana denial, where extra top-end slows the opening hand.

- Add role cards against spell combo: Flusterstorm, Swan Song, Void Mirror, and Disruptor Flute. Reduce main-deck emphasis on Ensnaring Bridge, slow artifact payoffs, and cards marked Card text check required when their exact text is not needed for the matchup’s first three turns.

- Add role cards against graveyard decks: Tormod's Crypt, Containment Priest, Swan Song, Flusterstorm, and Disruptor Flute. Reduce main-deck emphasis on slow top-end and artifact pieces that do not interact before the opponent’s first graveyard payoff.

- Add role cards against creature pressure: Sudden Demise, Portable Hole, Haywire Mite when targets exist, Pithing Needle when activated abilities matter, and the second Tezzeret, Cruel Captain for attrition. Reduce main-deck emphasis on fragile one-shot artifacts when life total and board stabilization are the limiting resources.

## Matchup Guidance

- Aggro: Stabilize before sculpting value, because Blue Artifacts wins creature matchups by converting cheap artifacts into board control and large Urza's Saga constructs. Keep hands that deploy early artifacts, red mana for Goblin Welder or Goblin Engineer, and a believable path to Ensnaring Bridge, Sudden Demise, Portable Hole, or construct bodies. Add role cards: Sudden Demise, Portable Hole, Haywire Mite when artifact or enchantment targets exist, Pithing Needle when activated abilities drive pressure, and Tezzeret, Cruel Captain for longer games. Reduce main-deck emphasis: slow top-end, speculative one-card artifacts with Card text check required, and hands that need multiple turns before affecting combat.

- Control: Lead with redundant engines instead of a single fragile commitment, because removal and permission punish all-in Goblin Welder, Goblin Engineer, or Emry, Lurker of the Loch lines. Favor hands with Urza's Saga, Mishra's Bauble, Urza's Bauble, Mox Opal, and multiple must-answer permanents; make the opponent answer constructs, recursion, and Tezzeret, Cruel Captain across separate turns. Add role cards: Flusterstorm, Swan Song, Disruptor Flute, Pithing Needle, Haywire Mite when hate permanents appear, and Tezzeret, Cruel Captain. Reduce main-deck emphasis: Ensnaring Bridge when the opponent is not pressuring combat, narrow creature-control cards, and low-impact artifacts if the game becomes about resilient threats.

- Combo: Spend early turns identifying the exact bottleneck, because Blue Artifacts cannot assume the opponent is slower than Goblin Engineer plus Goblin Welder setup. Keep hands with fast mana, a lock or disruption piece, and at least one engine route; avoid hands that only cantrip with Mishra's Bauble and Urza's Bauble while passing without interaction. Add role cards: Flusterstorm, Swan Song, Void Mirror, Disruptor Flute, Tormod's Crypt for graveyard combo, Containment Priest for creature-entry shortcuts, and Pithing Needle for activated engines. Reduce main-deck emphasis: Ensnaring Bridge, slow artifact payoffs, and fair attrition pieces unless their exact text is confirmed to disrupt the visible combo.

- Tempo: Preserve mana efficiency and artifact count, because tempo decks punish fetchland sequencing, tapped artifact lands, and expensive recovery turns. Prioritize Volcanic Island, Great Furnace, Seat of the Synod, Lotus Petal, and Mox Opal sequencing that lets Goblin Welder or Goblin Engineer resolve before soft permission matters. Use Urza's Saga constructs as blockers or race threats depending on visible pressure, and avoid sacrificing a stable battlefield artifact to Goblin Welder unless the return materially changes combat or protects an engine. Add role cards: Flusterstorm, Swan Song, Sudden Demise, Portable Hole, and Pithing Needle when a visible activated ability matters. Reduce main-deck emphasis: slow Tezzeret, Cruel Captain lines on low mana, speculative graveyard setup into open interaction, and Ensnaring Bridge when your hand size cannot drop quickly.

- Midrange: Trade resources deliberately, because this matchup is about making every removal spell answer the wrong card. Let expendable artifacts such as Mishra's Bauble, Urza's Bauble, Chromatic Star, Lotus Petal, and spent Mox Opal support Goblin Welder, Goblin Engineer, Emry, Lurker of the Loch, and Urza's Saga rather than treating them as isolated cards. Add role cards: Tezzeret, Cruel Captain, Pithing Needle, Haywire Mite, Portable Hole, and Swan Song if the opponent has high-impact noncreature spells. Reduce main-deck emphasis: narrow anti-combat cards when the opponent wins through attrition, and fragile single-artifact lines that lose to one removal spell without leaving a construct, graveyard target, or follow-up engine.

- Big mana: Pressure while disrupting the payoff window, because giving a big-mana deck unlimited turns lets it go over constructs and recursion. Urza's Saga should usually create a clock, Goblin Engineer should set up the artifact most likely to matter before the opponent’s payoff turn, and Goblin Welder should preserve mana-positive or high-impact artifacts instead of making cosmetic exchanges. Add role cards: Disruptor Flute, Pithing Needle, Swan Song, Flusterstorm when the payoff is spell-based, Void Mirror when colorless or alternate-cast sequences are visible, and Haywire Mite for artifact or enchantment engines. Reduce main-deck emphasis: creature sweepers, Portable Hole without targets, and Ensnaring Bridge when the opponent’s main path is noncombat.

- Graveyard: Decide whether you are the faster engine or the hate deck, because Emry, Lurker of the Loch and Goblin Welder also ask to use the graveyard. Against faster graveyard opponents, deploy Tormod's Crypt or Containment Priest before committing to slow recursion; against fair graveyard value, keep your own Goblin Engineer and Emry, Lurker of the Loch lines active while holding hate until a visible graveyard-dependent action appears. Add role cards: Tormod's Crypt, Containment Priest, Flusterstorm, Swan Song, Disruptor Flute, and Pithing Needle when an activated graveyard permanent is visible. Reduce main-deck emphasis: slow top-end and artifacts that do not interact before the opponent’s first graveyard payoff.

- Artifact/enchantment: Treat hate permanents as the first tactical problem, because one resolved permanent can disable Goblin Welder, Emry, Lurker of the Loch, Urza's Saga, or graveyard access. Use Haywire Mite, Portable Hole, Pithing Needle, Disruptor Flute, and Swan Song according to the visible permanent type and timing; do not assume Haywire Mite or Portable Hole answers a permanent unless the rules engine offers the legal action. Add role cards: Haywire Mite, Portable Hole, Pithing Needle, Disruptor Flute, Swan Song, and Tezzeret, Cruel Captain for longer permanent mirrors. Reduce main-deck emphasis: Ensnaring Bridge when the battlefield is about static hate rather than attacking, and artifact lines that walk into known activated hate.

- Go-wide: Prioritize sweepers and bridge states before value recursion, because a wide board can invalidate incremental Goblin Engineer or Emry, Lurker of the Loch turns. Sudden Demise is the cleanest sideboard reset when one visible color dominates; Ensnaring Bridge can buy time if hand size can be lowered; Urza's Saga constructs can block but should not be the only plan against many attackers. Add role cards: Sudden Demise, Portable Hole, Haywire Mite when targets exist, and Tezzeret, Cruel Captain if the game slows after stabilization. Reduce main-deck emphasis: single-target disruption that does not change the next combat step, and slow artifacts with Card text check required.

- Single-threat: Answer the engine around the threat when direct removal is not available, because Blue Artifacts often beats one large permanent by ignoring, blocking, naming, or bridging it rather than destroying it. Ensnaring Bridge is a key main-deck stabilizer if legal board state supports it; Urza's Saga constructs can race or double-block only when visible combat math permits; Pithing Needle and Disruptor Flute can matter if the threat depends on activated abilities or a repeated named card. Add role cards: Pithing Needle, Portable Hole for legal low-cost targets, Haywire Mite for artifact or enchantment threats, Swan Song for noncreature setup spells, and Tezzeret, Cruel Captain for attrition. Reduce main-deck emphasis: Sudden Demise against one large creature unless exact damage and color choices are legal and sufficient.

- Burn: Protect life total as a resource while avoiding self-inflicted tempo loss, because fetchlands, Lotus Petal bursts, and slow artifact loops can leave too little time. Favor fast Urza's Saga constructs, early Goblin Welder blockers, Ensnaring Bridge when hand size drops, and interaction that stops high-damage noncreature spells. Add role cards: Flusterstorm, Swan Song, Portable Hole for cheap permanent threats, Sudden Demise for creature-heavy versions, and Tezzeret, Cruel Captain only when the game visibly slows. Reduce main-deck emphasis: slow engines that do not affect life total, speculative Tezzeret, Cruel Captain starts, and Card text check required artifacts unless their legal action clearly stabilizes.

- Removal-heavy decks: Overload answers with recursive material, because every Goblin Welder, Goblin Engineer, Emry, Lurker of the Loch, Urza's Saga, and Tezzeret, Cruel Captain asks for a different answer. Do not expose Phyrexian Dragon Engine, Legion Extruder, Agatha's Soul Cauldron, Pinnacle Emissary, Sewer-veillance Cam, or Skateboard as decisive pieces until their text and current legal action justify the commitment; Card text check required for exact tactical roles. Add role cards: Tezzeret, Cruel Captain, Flusterstorm, Swan Song, Pithing Needle, Haywire Mite, and Disruptor Flute. Reduce main-deck emphasis: Ensnaring Bridge when combat is secondary, and all-in graveyard exchanges when the opponent has visible graveyard hate.

## Specific Matchup Notes
- General/archetype-only: Treat these notes as assumptions until the opponent reveals actual cards; visible cards, legal actions, public zones, and rules-engine prompts override every matchup shortcut. Against unknown Legacy opponents, lead with hands that produce early artifacts plus either Goblin Welder, Goblin Engineer, Emry, Lurker of the Loch, or Urza's Saga, because Blue Artifacts needs a board-based engine before it can convert recursion into pressure.

- Fast combo: Prioritize disruption and clock together, because passing with only a slow graveyard engine gives the opponent too much freedom. Add role cards: Flusterstorm, Swan Song, Disruptor Flute, Void Mirror, Pithing Needle, and Tormod's Crypt when the visible plan uses the graveyard. Priority targets are the opponent's enabling spell, activated permanent, graveyard payoff, or named engine card shown by public information; do not name or hold up hate for a card the opponent has not revealed unless matchup metadata explicitly identifies it.

- Fair blue or removal-heavy midrange: Make every answer trade down by spreading threats across creatures, artifacts, graveyard, and Urza's Saga. Add role cards: Tezzeret, Cruel Captain, Swan Song, Flusterstorm, Pithing Needle, Haywire Mite, and Disruptor Flute. Priority targets are graveyard hate, permanent hate, repeatable activated abilities, and counter windows that stop Goblin Engineer, Goblin Welder, Emry, Lurker of the Loch, or Tezzeret, Cruel Captain from establishing a lasting engine.

- Creature pressure: Stabilize combat before looping value, because the deck can lose while holding powerful but slow artifact actions. Add role cards: Sudden Demise, Portable Hole, Haywire Mite when a legal artifact or enchantment target exists, and Tezzeret, Cruel Captain for games that slow after the first reset. Priority targets are creatures that shorten the clock, evasive attackers, permanent pump sources, and hate pieces that keep Ensnaring Bridge or construct blockers from mattering.

- Graveyard opponent: Decide early whether Tormod's Crypt and Containment Priest are hate pieces or whether your own Goblin Welder and Emry, Lurker of the Loch engine must race. Add role cards: Tormod's Crypt, Containment Priest, Flusterstorm, Swan Song, Disruptor Flute, and Pithing Needle. Priority targets are visible graveyard actions, creature-entry replacement windows, and activated permanents; avoid firing Tormod's Crypt into low-impact graveyards if the opponent has not committed a payoff.

- Artifact, enchantment, or prison opponent: Remove or name the lock piece before pursuing cosmetic recursion. Add role cards: Haywire Mite, Portable Hole, Pithing Needle, Disruptor Flute, Swan Song, and Tezzeret, Cruel Captain. Priority targets are permanents that disable graveyards, activated abilities, artifact mana, Urza's Saga, attacks, or spell casting; use legal action text to confirm whether Haywire Mite, Portable Hole, or Pithing Needle actually interacts with the visible object.

## Risk Summary
- Mana risk: The deck can keep hands that look explosive but fail to cast colored spells after Lotus Petal or Mox Opal is spent. Protect blue for Emry, Lurker of the Loch and Tezzeret, Cruel Captain, red for Goblin Welder, Goblin Engineer, and Sudden Demise, and white only when sideboard cards such as Containment Priest or Portable Hole are present.

- Draw risk: Artifact-heavy hands without an engine can cycle Mishra's Bauble, Urza's Bauble, and Chromatic Star without affecting the board. Prefer hands where the cheap artifacts enable Mox Opal, Emry, Lurker of the Loch, Goblin Engineer, Goblin Welder, or Urza's Saga rather than hands that only inspect or replace cards.

- Over-sideboarding risk: Removing too many artifacts weakens Mox Opal, Emry, Lurker of the Loch, Goblin Welder, Goblin Engineer, and Urza's Saga. Add role cards only when they answer the opponent's revealed plan, and preserve enough cheap artifacts for metalcraft, recursion fodder, and construct size.

- Graveyard risk: The main deck depends heavily on graveyard access but is not only a graveyard deck. When opponent hate is visible, shift toward Urza's Saga constructs, Tezzeret, Cruel Captain, Ensnaring Bridge, and hard-cast artifacts instead of forcing Goblin Welder or Emry, Lurker of the Loch through disabled zones.

- Sweeper and removal risk: Creature engines are fragile when Goblin Welder, Goblin Engineer, and Emry, Lurker of the Loch all expose the same plan. Sequence so at least one threat leaves value behind, such as a tutored artifact, a stocked graveyard, an Urza's Saga chapter, or a planeswalker follow-up.

- Closer risk: The deck can stabilize without ending the game if Urza's Saga constructs, Phyrexian Dragon Engine, Legion Extruder, Pinnacle Emissary, Sewer-veillance Cam, Skateboard, or Tezzeret, Cruel Captain are misused. Card text check required for exact roles of Legion Extruder, Pinnacle Emissary, Sewer-veillance Cam, and Skateboard; commit them only when legal actions and visible state show pressure, stabilization, or engine payoff.

- Interaction risk: Flusterstorm, Swan Song, Disruptor Flute, Pithing Needle, Void Mirror, Tormod's Crypt, Haywire Mite, Portable Hole, and Sudden Demise each answer different problems. Do not spend a narrow answer on a low-impact object if a more decisive visible engine, payoff, or lethal setup is likely within the current public information.

- Sequencing risk: Goblin Engineer and Goblin Welder lines can accidentally strand the wrong artifact in the wrong zone. Before activating, verify the target artifact, the artifact to exchange or sacrifice, summoning sickness, graveyard access, and whether the opponent can profit from the same exchange window.

## Test Feedback Checklist
- Deciding factor: Identify the turn cycle that most changed the game, and note whether the cause was an engine connection, a missed pressure window, an unanswered opposing permanent, a mana bottleneck, or a failure to close after stabilization.

- Mulligans: Record whether each keep had a real engine path involving Goblin Welder, Goblin Engineer, Emry, Lurker of the Loch, Urza's Saga, Mox Opal, or Lotus Petal, and flag hands that only cycled Mishra's Bauble, Urza's Bauble, or Chromatic Star without board impact.

- Mana: Check whether colored mana was spent in the right order, especially blue for Emry, Lurker of the Loch and Tezzeret, Cruel Captain, red for Goblin Welder and Goblin Engineer, and white after sideboarding for Containment Priest or Portable Hole.

- Velocity: Ask whether early cheap artifacts enabled metalcraft, affinity-style casting, graveyard setup, or Urza's Saga pressure, rather than becoming low-impact churn that left the deck behind on board.

- Engine execution: Review every Goblin Engineer, Goblin Welder, and Emry, Lurker of the Loch decision for the intended artifact, source zone, destination zone, summoning-sickness constraint, and whether graveyard hate or removal made the line fragile.

- Removal and disruption: Record whether Pithing Needle, Disruptor Flute, Haywire Mite, Portable Hole, Sudden Demise, Flusterstorm, Swan Song, Void Mirror, Tormod's Crypt, and Containment Priest answered a decisive visible problem or were spent on a low-impact object.

- Sideboard impact: Compare post-board games to Game 1 by asking which sideboard card actually changed legal actions, combat math, stack decisions, graveyard access, or permanent functionality.

- Closing: Track whether wins came from Urza's Saga constructs, Tezzeret, Cruel Captain, Phyrexian Dragon Engine, Legion Extruder, Pinnacle Emissary, Sewer-veillance Cam, Skateboard, or recursive value, and flag games where stabilization failed to become pressure.

- Role assignment: Check whether the pilot correctly chose combo-engine, artifact-midrange, prison-stabilization, or disruptive-tempo posture from visible information, and note any turn where the deck played the wrong role for the board.

- Mistakes: Mark any action where the chosen legal action ignored public information, missed an available engine activation, exposed a key creature unnecessarily, spent Lotus Petal or Mox Opal into a later color shortage, or attacked when Ensnaring Bridge or blocking mattered more.

- Stranded cards: List cards stranded in hand or graveyard and explain whether the blocker was mana, missing artifact density, missing creature engine, opponent hate, timing, or card text uncertainty.

- Overperformers and underperformers: Name exact cards that generated material advantage or repeatedly failed to matter, with separate notes for main-deck cards and sideboard cards.

- Text uncertainty: Flag every decision involving Legion Extruder, Pinnacle Emissary, Sewer-veillance Cam, Skateboard, or other unfamiliar card text where Card text check required would have changed the tactical conclusion.

## First Tuning Questions
- Engine quantity: If games frequently lack an early engine, should the list preserve all 4 Goblin Welder, 4 Goblin Engineer, and 4 Emry, Lurker of the Loch while reconsidering lower-impact singleton artifacts?

- Artifact density: If Mox Opal, Emry, Lurker of the Loch, Goblin Welder, Goblin Engineer, or Urza's Saga underperform, is the problem too few cheap artifacts after sideboarding or too many artifacts that do not affect the board?

- Mana balance: If blue or red spells are stranded, should the Volcanic Island, Great Furnace, Seat of the Synod, Mountain, Plateau, Wooded Foothills, Scalding Tarn, and Bloodstained Mire mix change to protect early colored requirements?

- White splash pressure: If Containment Priest and Portable Hole are strong but hard to cast, does Plateau alone support the sideboard plan, or should white cards be limited to matchups where Lotus Petal and Mox Opal can reliably cover them?

- Aggro plan: If creature pressure beats the deck before engines matter, should Ensnaring Bridge, Sudden Demise, Portable Hole, Haywire Mite, or additional stabilizing artifacts receive more sideboard or main-deck emphasis?

- Control plan: If removal-heavy decks break up Goblin Welder, Goblin Engineer, and Emry, Lurker of the Loch, should the second Tezzeret, Cruel Captain become a more common post-board role card or move toward the main deck?

- Combo plan: If fast combo wins before pressure or stack interaction matters, should Flusterstorm, Swan Song, Disruptor Flute, Void Mirror, Tormod's Crypt, or Pithing Needle be increased or prioritized differently?

- Closer mix: If games stabilize but do not end, should the list adjust the balance among Phyrexian Dragon Engine, Legion Extruder, Pinnacle Emissary, Sewer-veillance Cam, Skateboard, Tezzeret, Cruel Captain, and Urza's Saga payoffs after card text is verified?

- Graveyard dependency: If opposing graveyard hate repeatedly blanks the strongest lines, should the post-board plan shift more heavily toward Urza's Saga, Tezzeret, Cruel Captain, Ensnaring Bridge, and hard-cast artifacts?

- Singleton toolbox: If Goblin Engineer searches repeatedly find the same artifact, should singleton slots such as Chromatic Star, Ensnaring Bridge, Agatha's Soul Cauldron, Phyrexian Dragon Engine, Legion Extruder, and Skateboard be rebalanced around the most common winning tutor targets?

- Sideboard slots: If any of Containment Priest, Void Mirror, Pithing Needle, Portable Hole, Haywire Mite, or Tormod's Crypt sits unused across matchups, should that slot become additional stack interaction, removal, or a redundant artifact answer?

- Role conflict: If the deck loses by half-committing to prison, combo, and midrange in the same game, should guides and sideboard plans force a clearer posture for each matchup rather than preserving every engine at once?

## Veles Tactical Policy

### Policy: Opening Hand Engine Gate
- Priority: High
- Decision families: mulligan
- Cards: Goblin Welder; Goblin Engineer; Emry, Lurker of the Loch; Urza's Saga; Mox Opal; Lotus Petal
- Phase windows: pregame mulligan decisions.
- Runtime cues: prompt:mulligan; hand contains exact registered cards.
- Use when: decide whether the hand has colored mana plus an engine creature, Urza's Saga pressure, or multiple cheap artifacts enabling Mox Opal and Emry, Lurker of the Loch.
- Avoid when: the hand only cycles Mishra's Bauble, Urza's Bauble, or Chromatic Star without a durable engine, pressure source, or sideboard hate piece.
- Instructions: Keep hands that can produce early red or blue and deploy a real engine; ship hands with artifacts but no colored path, no Urza's Saga, and no meaningful follow-up.
- Pilot skill floor: medium.
- No-API allowed: no

- Use when: choose the first permanent that turns graveyard artifacts, cheap artifacts, or Urza's Saga into continuing advantage.
- Avoid when: visible opposing mana or permanents make a fragile creature unlikely to untap and Urza's Saga or a protected line is available.
- Instructions: Lead with the engine that uses current resources this turn and next turn; prefer artifact lands when they enable metalcraft or affinity-style costs without exposing a needed colored source unnecessarily.
- Pilot skill floor: medium.
- No-API allowed: no

### Policy: Deterministic Exact Mana Payment
- Priority: Low
- Decision families: mana
- Cards: Mox Opal; Lotus Petal; Great Furnace; Seat of the Synod; Volcanic Island; Plateau; Mountain
- Phase windows: any payment prompt.
- Runtime cues: action:pay; action:add mana; action:activate Mox Opal; action:sacrifice Lotus Petal.
- Use when: the rules engine shows one pending cost, one legal action text pays the remaining required color or generic amount, and taking that action completes or advances the selected spell or ability payment.
- Avoid when: multiple visible payment lines preserve different colored sources, artifacts, or Lotus Petal for later decisions.
- Instructions: Execute the exact visible payment only after the strategic spell or ability is already selected; preserve Lotus Petal and colored lands when another legal payment produces the same result without consuming them.
- Pilot skill floor: low.
- No-API allowed: yes

- Phase windows: main phase Saga triggers, construct activations, combat.
- Runtime cues: action:create Construct; action:search; action:Urza's Saga.
- Use when: Urza's Saga can convert artifact count into a clock, stabilize combat, or find a one-mana artifact that changes the board.
- Avoid when: using mana on a construct prevents casting a necessary engine creature, removal spell, or sideboard interaction this turn.
- Instructions: Make constructs when pressure or blocking matters; search for the artifact whose visible function matters now, and require card text check for unfamiliar artifacts before treating them as toolbox targets.
- Pilot skill floor: medium.
- No-API allowed: no
- Light-model allowed: yes

### Policy: Goblin Engineer Search Gate
- Priority: High
- Decision families: selection; priority

- Runtime cues: action:search library; action:choose artifact; source:Goblin Engineer.
- Use when: Goblin Engineer can put the artifact that best supports the visible role into the graveyard or later battlefield plan.
- Avoid when: graveyard hate is visible, the artifact text is uncertain, or tutoring a fragile singleton does not affect the next turn cycle.
- Instructions: Use Ensnaring Bridge for survival posture, Phyrexian Dragon Engine for pressure or recursion if text supports it, and mark Legion Extruder or Skateboard as Card text check required before choosing them for deterministic lines.
- Pilot skill floor: high.
- No-API allowed: no
- Light-model allowed: yes

### Policy: Goblin Welder Exchange Gate
- Priority: High
- Decision families: interaction; selection; priority
- Cards: Goblin Welder; Great Furnace; Seat of the Synod; Phyrexian Dragon Engine; Ensnaring Bridge; Chromatic Star; Agatha's Soul Cauldron

- Runtime cues: action:activate Goblin Welder; action:target artifact; action:exchange.
- Use when: a legal exchange changes survival, pressure, or engine access from visible battlefield and graveyard objects.
- Avoid when: opponent controls graveyard hate, the exchange sacrifices a needed mana artifact, or target-pair text is ambiguous.
- Instructions: Route target-pair selection through reasoning; never assume the graveyard artifact resolves or remains legal after the rules engine exposes responses.
- Pilot skill floor: high.
- No-API allowed: no
- Light-model allowed: yes

### Policy: Emry Recursion Gate
- Priority: Medium
- Decision families: selection; priority; mana

- Runtime cues: action:activate Emry, Lurker of the Loch; action:cast from graveyard.
- Use when: Emry, Lurker of the Loch can turn graveyard artifacts into mana, cards, metalcraft, or board material this turn.
- Avoid when: activation exposes a needed artifact to exile, consumes mana needed for interaction, or only creates low-impact churn under a short clock.
- Instructions: Prefer artifacts that immediately unlock mana or board development before pure information artifacts; use baubles to fuel later turns when no urgent board action exists.
- Pilot skill floor: medium.
- No-API allowed: no
- Light-model allowed: yes

### Policy: Bauble Information Timing
- Priority: Low
- Decision families: priority; selection

- Phase windows: upkeep, main phase, end step, response windows.
- Runtime cues: action:activate Mishra's Bauble; action:activate Urza's Bauble; action:target self; action:target opponent.
- Use when: activating a bauble improves immediate selection, metalcraft, graveyard setup, or known-information planning.
- Avoid when: holding the artifact improves Mox Opal, construct size, Goblin Welder exchange material, or Ensnaring Bridge hand-size management.
- Instructions: Target choice is strategic unless exactly one legal target exists; respect hidden information and do not infer unknown cards beyond revealed engine output.
- Pilot skill floor: low.
- No-API allowed: no
- Light-model allowed: yes

### Policy: Ensnaring Bridge Survival Gate
- Priority: High
- Decision families: interaction; combat; priority
- Cards: Ensnaring Bridge
- Phase windows: main phases before combat, combat priority windows, sideboarded attrition games.
- Runtime cues: action:cast Ensnaring Bridge; battlefield:opposing attackers; hand_count.
- Use when: visible opposing power threatens lethal or a short clock and Ensnaring Bridge can materially restrict attacks from current hand size.
- Avoid when: hand size is too high for the visible attackers, the opponent has visible artifact removal pressure, or tapping out loses to a more immediate stack threat.
- Instructions: Treat Ensnaring Bridge as a prison commitment; plan hand size, bauble timing, and artifact deployment around the actual rules-engine attack legality.
- Pilot skill floor: medium.
- No-API allowed: no
- Light-model allowed: yes

### Policy: Tezzeret Commitment Gate
- Priority: High
- Decision families: priority; interaction; combat
- Cards: Tezzeret, Cruel Captain; Lotus Petal; Mox Opal; Volcanic Island; Seat of the Synod
- Phase windows: main phases with sufficient mana.
- Runtime cues: action:cast Tezzeret, Cruel Captain; action:activate Tezzeret, Cruel Captain.
- Use when: Tezzeret, Cruel Captain can survive the visible board or immediately create a decisive artifact-engine advantage.
- Avoid when: casting it consumes the only interaction mana, leaves lethal attackers unanswered, or card text check required prevents evaluating the mode.
- Instructions: Commit Tezzeret only after comparing board pressure, available protection through legal actions, and whether waiting preserves a stronger engine turn.
- Pilot skill floor: high.
- No-API allowed: no
- Light-model allowed: yes

### Policy: Artifact Payoff Text-Check Gate
- Priority: Medium
- Decision families: priority; selection; combat

- Phase windows: main phases, combat, activated-ability prompts.
- Runtime cues: action:cast Pinnacle Emissary; action:cast Sewer-veillance Cam; action:cast Legion Extruder; action:cast Skateboard; action:activate.
- Use when: the rules engine exposes legal action text for these cards and visible board state indicates the card's actual function matters.
- Avoid when: the tactical value depends on unverified card text or assumed synergy.
- Instructions: Card text check required; choose these actions from visible legal text only, and route unfamiliar mode, target, or activation decisions through light-model reasoning.
- Pilot skill floor: high.
- No-API allowed: no
- Light-model allowed: yes

### Policy: Stack Interaction Commitment
- Priority: High
- Decision families: interaction; priority
- Cards: Flusterstorm; Swan Song; Disruptor Flute; Void Mirror
- Phase windows: opponent spell casts, combo turns, protected engine turns.
- Runtime cues: action:cast Flusterstorm; action:cast Swan Song; action:activate Disruptor Flute; trigger:Void Mirror.
- Use when: visible stack action or known card name threatens immediate loss, disables the engine, or stops the selected win line.
- Avoid when: the spell is low impact, the opponent can pay through visible taxes, or spending permission prevents a stronger required answer this turn.
- Instructions: Spend permission on decisive stack objects and combo enablers; do not counter routine pressure if Ensnaring Bridge, constructs, or removal can answer it on board.
- Pilot skill floor: high.
- No-API allowed: no
- Light-model allowed: yes

### Policy: Permanent Hate Selection
- Priority: Medium
- Decision families: interaction; selection
- Cards: Pithing Needle; Haywire Mite; Portable Hole; Tormod's Crypt; Containment Priest; Void Mirror

- Runtime cues: action:cast Pithing Needle; action:activate Haywire Mite; action:cast Portable Hole; action:activate Tormod's Crypt; action:cast Containment Priest.
- Use when: a visible permanent, graveyard, or spell pattern blocks the engine or represents a faster opposing win.
- Avoid when: naming or targeting depends on hidden cards, uncertain card text, or low-impact objects that do not affect the next turn cycle.
- Instructions: Pick hate that changes legal actions now; route Pithing Needle names, Portable Hole targets, and graveyard-exile timing through reasoning unless a single legal target is exposed.
- Pilot skill floor: high.
- No-API allowed: no
- Light-model allowed: yes

### Policy: Sweeper And Removal Timing
- Priority: Medium
- Decision families: interaction; combat; mana
- Cards: Sudden Demise; Portable Hole; Haywire Mite
- Phase windows: precombat main phase, combat survival windows, postcombat cleanup of threats.
- Runtime cues: action:cast Sudden Demise; action:cast Portable Hole; action:activate Haywire Mite.
- Use when: visible creatures or permanents create a lethal clock, break Ensnaring Bridge math, or prevent engine creatures from functioning.
- Avoid when: removal misses the relevant color, target, or permanent type according to rules-engine legal actions.
- Instructions: Use Sudden Demise for board stabilization only after the engine exposes legal color and damage choices; use Portable Hole and Haywire Mite on objects that are actually legal and strategically decisive.
- Pilot skill floor: medium.
- No-API allowed: no
- Light-model allowed: yes

### Policy: Combat With Constructs And Engine Creatures
- Priority: Medium
- Decision families: combat
- Cards: Urza's Saga; Goblin Welder; Goblin Engineer; Emry, Lurker of the Loch; Ensnaring Bridge
- Phase windows: declare attackers, declare blockers, post-block priority.
- Runtime cues: action:declare attackers; action:declare blockers; battlefield:Construct.
- Use when: decide whether to race with constructs or preserve engine creatures for activations.
- Avoid when: attacking exposes Goblin Welder, Goblin Engineer, or Emry, Lurker of the Loch to a trade that stops the only engine line.
- Instructions: Attack with artifact bodies when pressure advances the clock; keep engine creatures back when their next activation is more valuable than combat damage.
- Pilot skill floor: medium.
- No-API allowed: no
- Light-model allowed: yes

### Policy: Sideboard Role Selection
- Priority: High
- Decision families: sideboard
- Cards: Flusterstorm; Swan Song; Disruptor Flute; Void Mirror; Tormod's Crypt; Containment Priest; Pithing Needle; Portable Hole; Haywire Mite; Sudden Demise; Tezzeret, Cruel Captain
- Phase windows: between games.
- Runtime cues: prompt:sideboard; match_stage:post-board; opponent_archetype.
- Use when: choose a legal registered sideboard plan that matches the opponent's visible speed, graveyard use, stack reliance, creature pressure, or permanent hate.
- Avoid when: a plan cuts too many engine pieces for hate cards that do not affect the matchup's primary axis.
- Instructions: Bring stack interaction versus fast spell decks, graveyard hate versus graveyard engines, removal versus creature pressure, permanent hate versus named activated abilities or artifacts/enchantments, and Tezzeret for attrition.
- Pilot skill floor: high.
- No-API allowed: no
- Light-model allowed: yes
