# Strategy Specifications
## Deck Name And Archetype

Painter is a Legacy red artifact combo-control deck built around the registered `Painter's Servant` plus `Grindstone` kill, with graveyard-artifact recursion from `Goblin Engineer` and `Goblin Welder`, pressure and filtering from `Fable of the Mirror-Breaker`, and backup artifact-engine threats through `Agatha's Soul Cauldron`, `Phyrexian Devourer`, `Phyrexian Dragon Engine`, `Chaos Defiler`, and `Urza's Saga`. The deck should be piloted as a hybrid: assemble deterministic combo wins when protected or forced, control the opponent's key stack actions with `Pyroblast` and `Red Elemental Blast` once `Painter's Servant` changes colors, and use artifact tutoring/recursion to convert small board resources into inevitability.

Validation status: the registered list is 60 main-deck cards and 15 sideboard cards, matching the active Legacy validation contract of at least 60 main and at most 15 sideboard. The active format is Legacy, and the supplied format-aware validation result passes. The current archetype tags are normalized as combo, control, and artifact; the duplicate tag string does not change runtime role classification.

Stock versus rogue status: this is a recognizable Legacy Painter shell with a rogue or hybrid finish package. The stock core is `Painter's Servant`, `Grindstone`, `Goblin Engineer`, `Goblin Welder`, `Pyroblast`, `Red Elemental Blast`, `Lotus Petal`, `Simian Spirit Guide`, `Ancient Tomb`, `City of Traitors`, `Great Furnace`, and `Urza's Saga`. The hybrid identity comes from `Agatha's Soul Cauldron` with `Phyrexian Devourer`, the single `Phyrexian Dragon Engine`, the single `Chaos Defiler`, the single `Ensnaring Bridge`, the single `Soul-Guide Lantern`, and the registered card `Skateboard`. Card text check required for `Skateboard`; until verified, treat it as a conditional registered artifact slot and do not assume its tactical role beyond visible legal actions.

Mana and role concerns: the deck is explosive but damage-prone because `Ancient Tomb` accelerates combo turns while pressuring its controller's life total. `City of Traitors`, `Lotus Petal`, and `Simian Spirit Guide` create burst turns but reduce long-game resources, so a decision agent should spend them for protected combo, urgent lock-piece timing, or tempo-critical `Goblin Engineer` and `Fable of the Mirror-Breaker` lines rather than routine low-impact development. `Mountain`, `Great Furnace`, `Arena of Glory`, and `Urza's Saga` shape different plans: stable red mana, artifact recursion material, creature pressure or haste utility if legal, and tutor-construct pressure respectively.

Legality and runtime discipline: Veles must follow the rules engine's legal action list before applying this guide. Do not assume `Painter's Servant` is currently naming a relevant color unless the visible game state or action history proves it. Do not assume `Pyroblast` or `Red Elemental Blast` can target a spell or permanent unless the engine exposes the action. Do not assume `Goblin Welder`, `Goblin Engineer`, `Agatha's Soul Cauldron`, `Grindstone`, `Soul-Guide Lantern`, `Ensnaring Bridge`, `Pithing Needle`, `Blood Moon`, `Magus of the Moon`, `Leyline of the Void`, `Mindbreak Trap`, `Fury`, or `Abrade` have usable modes outside the visible legal actions.

Opponent information status: no specific opponent decklist, matchup, opening hand, play/draw status, or metagame target is supplied in this batch. Treat opponent identity as unknown until Veles provides public information, matchup labels, revealed cards, sideboarding stage, or action history. Use sideboard and matchup policies later only when the runtime matchup label or visible opponent cards justify them, and prefix any metagame-only card examples outside registered names when they are not part of this deck.

## Thesis

Painter assembles a two-card library-kill with `Painter's Servant` plus `Grindstone`, then uses red artifact recursion, burst mana, and blast effects to make that kill happen through disruption. The default winning plan is to resolve or recur `Painter's Servant`, choose a color that makes `Grindstone` lethal when the rules engine exposes the activation line, and protect the turn with `Pyroblast` or `Red Elemental Blast` when those actions are legal. The backup plan is to convert `Goblin Engineer`, `Goblin Welder`, `Urza's Saga`, `Fable of the Mirror-Breaker`, `Chaos Defiler`, `Phyrexian Dragon Engine`, and artifact bullets into repeated material advantage until the opponent is forced to answer the combo under worse conditions.

Prioritize compact combo assembly over fair attrition unless the visible board or known matchup makes immediate combo unsafe. `Painter's Servant` without `Grindstone` turns `Pyroblast` and `Red Elemental Blast` into broad interaction if the engine confirms legal targets, so the first copy can be a control piece rather than only a kill piece. `Grindstone` without `Painter's Servant` is usually an incomplete payoff, but it remains important because `Urza's Saga`, `Goblin Engineer`, and artifact recursion can find or reuse it.

Do not pilot this deck as generic red aggro, generic prison, or a pure artifact beatdown deck. `Lightning Bolt`, Construct tokens from `Urza's Saga`, `Fable of the Mirror-Breaker`, `Goblin Welder`, `Goblin Engineer`, `Chaos Defiler`, and `Phyrexian Dragon Engine` can win damage races, but combat is normally a pressure valve that buys time, taxes removal, or finishes after combo disruption. `Blood Moon`, `Magus of the Moon`, `Ensnaring Bridge`, `Soul-Guide Lantern`, `Pithing Needle`, `Abrade`, `Fury`, `Leyline of the Void`, and `Mindbreak Trap` are role cards, not reasons to abandon the core combo-control plan unless the matchup or visible battlefield demands it.

Spend scarce burst resources only when the resulting turn matters. `Ancient Tomb`, `City of Traitors`, `Lotus Petal`, and `Simian Spirit Guide` should accelerate protected combo, early `Goblin Engineer`, early `Fable of the Mirror-Breaker`, urgent sideboard hate, or a decisive lock/bridge turn. Avoid using one-shot mana for low-impact actions when the hand already has stable `Mountain`, `Great Furnace`, `Arena of Glory`, or `Urza's Saga` development.

## Role Package

- Threats: `Painter's Servant` is the central must-answer permanent because it enables `Grindstone`, upgrades blasts, and changes many future priorities. `Urza's Saga` creates Construct pressure while tutoring artifacts, and its tokens can force the opponent to react before the combo is complete. `Fable of the Mirror-Breaker` threatens filtering, mana pressure through its token, and a transformed engine if the game slows. `Chaos Defiler` is the large stabilizing threat and removal-adjacent payoff when legal actions expose it. `Phyrexian Dragon Engine` is a card-advantage and combat body when cast, reanimated, or reused legally.

- Payoffs: `Grindstone` is the primary kill payoff with `Painter's Servant`. `Agatha's Soul Cauldron` plus `Phyrexian Devourer` is a secondary engine or combo-adjacent package, but exact execution must follow visible legal actions because counters, activated abilities, and creature eligibility matter. `Ensnaring Bridge` is a payoff for low-hand defensive games, not a win condition by itself. `Soul-Guide Lantern` is a graveyard-control payoff that also feeds artifact synergies.

- Engines: `Goblin Engineer` finds key artifacts, loads the graveyard for recursion, and turns singletons into accessible tools. `Goblin Welder` converts graveyard artifacts and battlefield artifacts into recurring threats, bullets, or combo pieces when legal targets align. `Fable of the Mirror-Breaker` smooths dead draws and turns later creature copies into a snowball engine. `Urza's Saga` is both mana source and artifact tutor, so protect its chapter timing when `Grindstone`, `Soul-Guide Lantern`, `Lotus Petal`, or artifact material is needed.

- Velocity: `Fable of the Mirror-Breaker` is the main card selection tool. `Goblin Engineer` is tutor-velocity rather than card quantity, so its target should match the current missing piece or defensive need. `Lotus Petal`, `Simian Spirit Guide`, `Ancient Tomb`, and `City of Traitors` are tempo velocity and should be cashed in for turns that change the game state materially.

- Interaction: `Pyroblast` and `Red Elemental Blast` protect the combo and answer opposing spells or permanents only when the rules engine exposes legal targets. `Lightning Bolt` handles small creatures, planeswalkers if legal, and reach. `Abrade`, `Fury`, `Mindbreak Trap`, `Pithing Needle`, `Blood Moon`, `Magus of the Moon`, and `Leyline of the Void` become specialized interaction after sideboarding.

- Protection: `Pyroblast` and `Red Elemental Blast` are the primary stack and permanent protection package once `Painter's Servant` makes targets legal. `Ensnaring Bridge` protects life total against creature pressure. `Soul-Guide Lantern` and `Leyline of the Void` protect against graveyard lines. `Mindbreak Trap` protects against spell-chain turns.

- Recursion: `Goblin Welder`, `Goblin Engineer`, `Great Furnace`, `Lotus Petal`, `Grindstone`, `Soul-Guide Lantern`, `Phyrexian Dragon Engine`, `Phyrexian Devourer`, `Ensnaring Bridge`, `Chaos Defiler`, and `Skateboard` can all matter as artifact objects if the engine exposes legal exchange, tutor, or graveyard actions. Card text check required for `Skateboard`; treat it as an artifact role-player only when legal actions reveal its function.

- Mana: `Mountain` supplies stable red mana. `Ancient Tomb` and `City of Traitors` provide explosive colorless mana with real costs. `Great Furnace` supports red mana and artifact recursion. `Arena of Glory` should be used according to visible legal actions and current creature timing. `Urza's Saga` must be sequenced as both land and delayed artifact access.

- Sideboard modules: `Abrade` covers artifacts and creatures. `Fury` covers creature-heavy starts. `Leyline of the Void` covers graveyard strategies. `Mindbreak Trap` covers high-spell-count turns. `Magus of the Moon` and `Blood Moon` punish nonbasic mana. `Pithing Needle` answers activated abilities when the visible target is known.

## Primary Win Conditions

- Primary kill: assemble `Painter's Servant` plus `Grindstone`, then activate `Grindstone` targeting the opponent when the rules engine exposes that legal action. Set up by casting either piece naturally, finding `Grindstone` with `Urza's Saga`, putting artifacts into the graveyard with `Goblin Engineer`, or recurring a destroyed piece with `Goblin Welder` or `Goblin Engineer` if legal targets line up. Prioritize this line when you can pay for activation now or next turn, when `Pyroblast` or `Red Elemental Blast` can protect the turn, or when waiting lets the opponent untap into visible pressure or known interaction.

- Protection rule: treat `Painter's Servant` as both combo piece and blast enabler, not just a creature. If the engine asks for a color choice and no visible board state demands another color, prefer the color that makes `Pyroblast` and `Red Elemental Blast` live against the widest visible set of opposing spells and permanents; confirm legal targets from the engine before using a blast. Save blasts for removal, counterplay, or a decisive permanent when the combo is close; spend them earlier only if the visible threat will prevent the combo from resolving or surviving.

- Tutor rule: use `Urza's Saga` to get the missing artifact that changes the next turn. `Grindstone` is the default kill piece, `Soul-Guide Lantern` is the graveyard-control bullet, and `Lotus Petal` can matter when the immediate line needs one more mana. Do not tutor a low-impact artifact over `Grindstone` when `Painter's Servant` is already present and the opponent is not presenting a lethal or lock-breaking threat.

- Recursion rule: use `Goblin Welder` and `Goblin Engineer` to make answered combo pieces temporary setbacks. Exchange expendable artifacts such as `Great Furnace`, `Lotus Petal`, `Soul-Guide Lantern`, spent `Grindstone`, or artifact bodies only when the visible battlefield and graveyard produce a legal upgrade. Avoid sacrificing the only active `Grindstone` or only relevant artifact mana unless the returned permanent creates a stronger immediate line.

## Secondary Win Conditions

- Construct pressure: let `Urza's Saga` create a real combat clock when combo access is delayed or the opponent is overloaded on removal for `Painter's Servant`. Construct tokens scale with artifacts such as `Great Furnace`, `Lotus Petal`, `Grindstone`, `Soul-Guide Lantern`, `Agatha's Soul Cauldron`, `Ensnaring Bridge`, and other artifact permanents, so sequence artifacts before attacks when that legally increases damage without exposing the combo unnecessarily.

- Fable pressure: use `Fable of the Mirror-Breaker` as the fair-game engine that turns awkward hands into live combo, mana, or interaction. The Goblin token pressures planeswalkers and creates Treasure if it connects; the looting chapter should discard redundant lands, extra legendary-like low-value engines, dead blasts without legal targets, or artifacts that become better in the graveyard for `Goblin Welder` and `Goblin Engineer`. If it transforms, copy decisions should follow visible legal actions and favor `Goblin Engineer`, `Goblin Welder`, `Painter's Servant`, `Phyrexian Dragon Engine`, or `Chaos Defiler` only when the copy creates immediate material or combo progress.

- Cauldron package: treat `Agatha's Soul Cauldron` plus `Phyrexian Devourer` as a secondary engine/combo-adjacent plan, not as an assumed kill. Card text check required for exact activated-ability and counter interactions at runtime; choose this line only when legal actions show the relevant exile, ability, counter, or creature actions and the visible board supports committing graveyard resources. Protect it less aggressively than the `Painter's Servant` plus `Grindstone` kill unless it is the only live route.

- Value threat: use `Chaos Defiler` as a stabilizing and closing threat when the game has become about permanents rather than speed. Card text check required for exact resolution and target structure; if the engine exposes legal cast, recursion, or copy actions, prioritize it when the opponent has key permanents, when life total pressure must be reversed, or when combo pieces have been removed repeatedly.

- Backup damage: finish games with `Lightning Bolt`, creature attacks, `Phyrexian Dragon Engine`, Construct tokens, `Goblin Engineer`, `Goblin Welder`, and `Fable of the Mirror-Breaker` tokens when the opponent has spent resources stopping the combo. Do not overextend attackers into bad blocks if `Ensnaring Bridge` or a protected combo turn is the safer route.

## Emergency Lines

- Behind on life: stabilize before racing unless the combo kill is immediately available. `Ensnaring Bridge` becomes the priority artifact when creature attacks are the visible danger, `Lightning Bolt` should remove attackers that shorten the clock, and `Fury` after sideboarding can reset small-creature boards if legal. Use `Ancient Tomb` carefully when its damage changes the opponent's clock.

- Behind on board: trade resources for time until `Painter's Servant` plus `Grindstone`, `Chaos Defiler`, `Ensnaring Bridge`, or large Constructs can matter. Use `Pyroblast` and `Red Elemental Blast` only on legal targets that stop lethal pressure, protect the stabilizer, or preserve the combo. Do not spend a blast on a marginal permanent while a known lethal attack or combo-disrupting spell remains possible.

- Behind on cards: lean on engines that convert position rather than raw hand size. `Fable of the Mirror-Breaker`, `Goblin Engineer`, `Goblin Welder`, `Urza's Saga`, `Phyrexian Dragon Engine`, and `Chaos Defiler` can rebuild from low resources if their legal actions are available. Preserve unique bullets like `Soul-Guide Lantern`, `Ensnaring Bridge`, and `Grindstone` unless using them immediately unlocks a stronger recursive exchange.

- Behind on mana: prioritize stable land development over flashy one-shot turns unless the current legal action wins or prevents losing. `Mountain`, `Great Furnace`, and `Urza's Saga` support longer games; `Lotus Petal`, `Simian Spirit Guide`, `Ancient Tomb`, and `City of Traitors` should be spent on decisive setup, hate, or protected combo turns. Avoid playing `City of Traitors` before necessary if another land drop will be needed.

- Combo pieces removed: switch to recursion, Saga pressure, and Fable filtering instead of forcing dead lines. `Goblin Engineer` can find missing artifacts, `Goblin Welder` can return artifacts from graveyard, and `Urza's Saga` can find another `Grindstone`; if `Painter's Servant` copies are exhausted, win through Constructs, `Chaos Defiler`, `Phyrexian Dragon Engine`, and burn.

- Graveyard recursion shut off: treat `Goblin Welder` and `Goblin Engineer` as creatures with reduced text and pivot to natural draws, `Urza's Saga`, `Fable of the Mirror-Breaker`, and hard-cast threats. Do not invest extra artifacts into the graveyard when visible hate prevents legal recursion value.

## Resource Model

- Life is a spendable clock resource, not a shield. Use `Ancient Tomb` damage and aggressive artifact deployment when the line creates `Painter's Servant` plus `Grindstone`, a protected setup turn, or a stabilizer such as `Ensnaring Bridge`; slow down on `Ancient Tomb` when visible attackers make the two life equivalent to losing a full turn. `Lightning Bolt` can buy life by removing a creature, but it should not be spent on small damage prevention if a combo-protecting blast or imminent kill matters more.

- Hand size is fuel for filtering, protection, and `Ensnaring Bridge`. Keep enough cards to represent `Pyroblast`, `Red Elemental Blast`, `Lightning Bolt`, or combo follow-up, but let `Fable of the Mirror-Breaker` discard redundant lands, dead blasts without legal targets, extra one-shot mana, or artifacts that improve `Goblin Welder` and `Goblin Engineer` exchanges. When `Ensnaring Bridge` is the stabilizer, emptying hand can become a defensive objective; do not preserve speculative cards if lowering hand size prevents lethal attacks.

- Mana converts into initiative more sharply than raw card count. `Lotus Petal`, `Simian Spirit Guide`, `Ancient Tomb`, and `City of Traitors` are best when they accelerate `Painter's Servant`, `Goblin Engineer`, `Fable of the Mirror-Breaker`, `Magus of the Moon`, `Blood Moon`, or a same-turn `Grindstone` activation. Avoid spending one-shot mana on low-impact sequencing if the visible game is likely to require protection, activation mana, or a second spell in the same turn.

- Board presence is either combo infrastructure or time. `Painter's Servant`, `Grindstone`, `Goblin Welder`, `Goblin Engineer`, `Agatha's Soul Cauldron`, `Urza's Saga` Constructs, `Ensnaring Bridge`, and `Fable of the Mirror-Breaker` all change what future legal actions are worth; protect the permanent that unlocks the next decisive action, not automatically the most expensive one. Treat `Great Furnace` as both a land and an artifact resource, so sacrificing or welding it is only correct when the returned artifact is worth the lost mana source.

- Graveyard is an extension of the hand only while legal recursion exists. Put artifacts into the graveyard with `Goblin Engineer`, combat trades, sacrificed `Lotus Petal`, used `Soul-Guide Lantern`, or destroyed combo pieces when `Goblin Welder` or `Goblin Engineer` can convert them into a better permanent. Do not voluntarily load critical artifacts into the graveyard through visible `Leyline of the Void`-style hate or opposing graveyard control unless the rules engine still exposes the intended legal action.

- Exile is mostly a cost or lock zone. `Agatha's Soul Cauldron` and `Soul-Guide Lantern` can turn exile into value or disruption, but Card text check required for exact `Agatha's Soul Cauldron`, `Phyrexian Devourer`, and `Skateboard` interactions. Use `Leyline of the Void` after sideboarding to deny graveyard decks before they start; use `Mindbreak Trap` as stack exile only for legal opposing spell patterns shown by the engine.

- Information is a protection resource. A visible blue permanent or spell increases the value of `Pyroblast` and `Red Elemental Blast`; a visible graveyard engine increases `Soul-Guide Lantern` and `Leyline of the Void`; a visible activated ability target increases `Pithing Needle`; a visible nonbasic-heavy board increases `Magus of the Moon` and `Blood Moon`. Do not assume hidden cards; act on revealed cards, public zones, current legal actions, and matchup role guidance.

- Sideboard bullets convert narrow resources into decisive turns. `Abrade` is flexible artifact or creature interaction, `Fury` buys tempo against creature boards, `Leyline of the Void` attacks graveyard reliance without spending mana, `Mindbreak Trap` covers fast stack-based turns, `Magus of the Moon` and `Blood Moon` punish nonbasic mana, and `Pithing Needle` answers a specific visible activated ability or known matchup engine.

## Mana Guide

- Utility-land sequencing: explicitly track `Great Furnace`, `Ensnaring Bridge` as the deck's named nonbasic or utility-land decisions. Use these lands to satisfy the next visible color or utility requirement before taking speculative lines: play or fetch colored sources before cantrips and discard that need exact mana, keep utility lands when their activated or disruptive text is part of the current plan, and delay utility-land sacrifices until the follow-up spell or ability is already legal. When choosing between a stable colored source and a utility land, choose the source that casts the current hand under visible pressure, then use the utility land once the required colors are secure.

- Red mana is the deck's required color, and colorless acceleration is the deck's speed. Prioritize hands that can produce red for `Goblin Engineer`, `Goblin Welder`, `Painter's Servant`, `Fable of the Mirror-Breaker`, `Lightning Bolt`, `Pyroblast`, or `Red Elemental Blast`, while using `Ancient Tomb`, `City of Traitors`, `Urza's Saga`, and `Lotus Petal` to cover artifact costs and burst turns. A hand with only colorless lands needs a strong reason, such as immediate `Grindstone`, `Urza's Saga`, and a clear path to red.

- Keep mana when the hand has a land plan and a spell plan. Strong keeps include red source plus `Painter's Servant` or `Goblin Engineer`, `Urza's Saga` plus artifact follow-up, `Ancient Tomb` plus a meaningful two-mana permanent, or acceleration plus protection. Mulligan hands that cannot cast red spells, cannot advance combo or Saga pressure, or rely on `City of Traitors` as the only land while needing multiple future land drops.

- Sequence lands to preserve future choices. Play `Mountain` or `Great Furnace` before `City of Traitors` when the hand needs normal development; play `City of Traitors` only when the immediate turn uses the burst or the next land drop is unlikely to matter. Play `Ancient Tomb` early when speed matters, but choose `Mountain` first when life pressure is visible and the same spell can wait without losing the strategic window.

- Treat `Urza's Saga` as a delayed land, threat, and tutor. Play it early when the game plan wants Constructs or a future `Grindstone`, `Soul-Guide Lantern`, or `Lotus Petal`; delay it when losing access to normal mana timing would prevent casting `Goblin Engineer`, `Fable of the Mirror-Breaker`, or interaction. Before the final chapter, float or use mana only if the engine exposes legal timing that preserves the intended tutor or activation.

- Play lands before draw or selection when extra mana changes legal actions this turn. Lead with a land before `Fable of the Mirror-Breaker` chapter decisions, `Phyrexian Dragon Engine` actions, or artifact activation if the new mana enables casting, welding, activating `Grindstone`, or holding `Pyroblast`. Delay the land drop when looting or selection could reveal whether `City of Traitors`, `Urza's Saga`, `Great Furnace`, or `Mountain` is the better land for the turn.

- Spend one-shot mana only for decisive compression. `Lotus Petal` and `Simian Spirit Guide` are best for same-turn combo deployment, fast `Fable of the Mirror-Breaker`, surprise interaction, early lock pieces, or paying for a protected `Grindstone` line. Do not burn them merely to cast a replaceable artifact if holding them preserves a future protected activation or post-sideboard hate turn.

- Count activation mana before committing combo pieces. `Painter's Servant` plus `Grindstone` requires not only permanents but the legal activation window and enough mana after protection or taxes. If a line taps `Ancient Tomb`, sacrifices `Lotus Petal`, or uses `City of Traitors`, verify the resulting legal actions still include the intended cast, target, weld, or activation before choosing it.

## Mulligan Guide

- Strong keep: keep a hand that has red mana, a two-mana engine creature, and either a combo piece or protection. `Mountain` plus `Ancient Tomb` with `Painter's Servant`, `Grindstone`, and `Pyroblast` is a premium start because it threatens a fast combo while retaining interaction if the rules engine exposes a blue target.

- Strong keep: keep `Urza's Saga` hands that already contain red mana or a castable engine. `Urza's Saga`, `Mountain`, `Goblin Engineer`, and any artifact among `Grindstone`, `Soul-Guide Lantern`, `Lotus Petal`, or `Great Furnace` gives a real plan through Constructs, tutoring, and graveyard setup.

- Medium keep: keep slower hands with `Fable of the Mirror-Breaker` when mana is stable and at least one early play exists. A hand of two red sources, `Fable of the Mirror-Breaker`, `Pyroblast`, `Goblin Welder`, and a recoverable artifact is acceptable, but it is weaker against fast combo or heavy pressure.

- Risky keep: keep one-land `Ancient Tomb` or `City of Traitors` hands only when the first two turns are already scripted by visible legal actions. `Ancient Tomb`, `Lotus Petal`, `Painter's Servant`, `Grindstone`, and `Red Elemental Blast` can be worth it; `City of Traitors` plus expensive red spells and no second mana source is not.

- Automatic ship: mulligan hands with no land, no red source and no `Lotus Petal` or `Simian Spirit Guide`, or no meaningful turn-one or turn-two action. Also ship hands that contain only reactive `Pyroblast`, `Red Elemental Blast`, or `Lightning Bolt` with no combo, `Urza's Saga`, `Goblin Engineer`, `Goblin Welder`, or `Fable of the Mirror-Breaker` plan.

- Matchup-dependent keep: keep `Soul-Guide Lantern` or post-board `Leyline of the Void` hands more often when the opponent's public deck identity or revealed cards show graveyard reliance. Keep `Magus of the Moon` or `Blood Moon` hands more often when the opponent's visible mana or matchup label is nonbasic-heavy, but do not keep a hand that cannot cast the lock piece.

- Play/draw adjustment: on the play, value `Ancient Tomb`, `Lotus Petal`, `Simian Spirit Guide`, `Painter's Servant`, and `Goblin Engineer` because initiative can decide whether protection matters. On the draw, raise the bar for fragile all-in hands and value `Lightning Bolt`, `Pyroblast`, `Red Elemental Blast`, `Ensnaring Bridge`, and `Fable of the Mirror-Breaker` when they answer or stabilize against visible pressure.

- Trap hand: do not keep a hand that looks explosive but loses to its own sequencing, such as `City of Traitors`, `Urza's Saga`, `Fable of the Mirror-Breaker`, `Chaos Defiler`, and no red source. Do not keep multiple `Pyroblast` effects without `Painter's Servant` or a visible blue matchup reason.

## Turn Arc

- Turn 1: lead with the land that preserves the next two turns. Prefer `Mountain` or `Great Furnace` into `Goblin Welder`, `Soul-Guide Lantern`, or held `Pyroblast`; prefer `Ancient Tomb` when it casts `Painter's Servant`, `Grindstone`, or accelerates `Fable of the Mirror-Breaker`; prefer early `Urza's Saga` when the hand wants chapter pressure and a future `Grindstone` tutor.

- Turn 1 deviation: use `Lotus Petal` or `Simian Spirit Guide` only when the burst creates a real engine turn. Fast `Painter's Servant`, fast `Goblin Engineer`, protected interaction, or post-board `Magus of the Moon`/`Blood Moon` can justify it; a merely earlier low-impact artifact usually should wait.

- Turn 2: assemble either combo infrastructure or a resilient engine. Cast `Goblin Engineer` to put the missing artifact or a future `Goblin Welder` target into the graveyard, cast `Painter's Servant` when protection or activation timing is credible, or advance `Urza's Saga` while holding interaction if the opponent is likely to fight on the stack.

- Turn 2 deviation: hold `Painter's Servant` when exposing it gives the opponent a full untap and no immediate payoff follows. Against visible pressure, prioritize `Lightning Bolt`, `Fury`, `Ensnaring Bridge`, or a Construct line over a fragile combo piece if the engine does not show a same-turn or protected follow-up.

- Turn 3: convert setup into pressure, protection, or a deterministic combo attempt. Use `Urza's Saga` to make a Construct when it is legal and relevant, deploy `Fable of the Mirror-Breaker` if the game is becoming resource-based, or attempt `Painter's Servant` plus `Grindstone` only after confirming mana, priority, and protection actions remain legal.

- Turn 3 deviation: with `Goblin Welder` active, prioritize artifact positioning over raw casting. Returning `Grindstone`, `Painter's Servant`, `Ensnaring Bridge`, `Phyrexian Dragon Engine`, or `Soul-Guide Lantern` is correct only when the visible exchange is better than the artifact being sacrificed, especially if sacrificing `Great Furnace` reduces future mana.

- Turns 4-5: force the opponent to answer multiple axes. Combine `Fable of the Mirror-Breaker`, `Urza's Saga` Constructs, `Goblin Engineer`, and `Goblin Welder` to overload removal while keeping `Pyroblast` or `Red Elemental Blast` for decisive blue interaction or protection after `Painter's Servant` is active.

- Turns 4-5 deviation: shift into containment when racing is unsafe. Use `Ensnaring Bridge` to buy time, `Soul-Guide Lantern` or `Leyline of the Void` to suppress graveyard engines, `Abrade` or `Lightning Bolt` for visible threats, and `Magus of the Moon` or `Blood Moon` when the opponent's current mana makes the lock meaningful.

- Late game: treat every legal action as either a protected combo attempt, a Saga/Construct damage plan, or a recursion lock. Preserve `Pyroblast` and `Red Elemental Blast` for the stack or permanent that actually stops the winning line, and use `Agatha's Soul Cauldron`, `Phyrexian Devourer`, `Phyrexian Dragon Engine`, `Chaos Defiler`, and `Skateboard` only according to visible legal actions; Card text check required for exact late-game combo roles involving `Agatha's Soul Cauldron`, `Phyrexian Devourer`, and `Skateboard`.

## Card Roles

- `Painter's Servant`: treat this as the deck's defining combo and interaction converter, not just a creature. Cast it when it enables an immediate or protected `Grindstone` kill, turns `Pyroblast` or `Red Elemental Blast` into universal interaction, or forces the opponent to answer a threat while you have recursion from `Goblin Welder` or `Goblin Engineer`. The default color with blast-heavy hands is usually blue, but runtime legality and visible action text still control the choice. Avoid exposing `Painter's Servant` into open removal when no payoff, protection, or recursion is ready.

- `Grindstone`: use this as the primary kill piece and a key `Urza's Saga` target. Prioritize finding or deploying it when `Painter's Servant` is present, when `Goblin Engineer` can stock it for later recursion, or when the opponent is shields-down and the activation can happen before they untap. Do not spend scarce mana activating it without the combo unless the rules engine shows a meaningful non-combo action and the game plan has shifted to attrition.

- `Pyroblast`: preserve this for decisive stack fights, protection, or permanent interaction once `Painter's Servant` makes targets blue. Before `Painter's Servant`, use it only against visible blue spells or blue permanents that matter more than protecting the combo. A common mistake is firing `Pyroblast` at a medium card and then losing the protected combo window; another is holding it too long when the opponent's only relevant answer is already on the stack.

- `Red Elemental Blast`: treat this as copies five and six of the same strategic shield as `Pyroblast`, with exact legal targeting determined by the rules engine. Use it to force through `Painter's Servant`, protect `Grindstone`, answer visible blue pressure, or fight opposing stack interaction. Do not assume it can target a nonblue object unless `Painter's Servant` or visible game text makes that legal.

- `Goblin Engineer`: cast this early when it creates a concrete artifact plan. It can set up `Grindstone`, `Soul-Guide Lantern`, `Ensnaring Bridge`, `Phyrexian Dragon Engine`, `Phyrexian Devourer`, `Skateboard`, or `Chaos Defiler` lines depending on visible legal actions and graveyard state. Use it as a bridge between combo and recursion, not as a generic body. Avoid tutoring an artifact to the graveyard when graveyard hate is visible and no `Goblin Welder` or later exchange line is available.

- `Goblin Welder`: protect this when it represents a repeatable artifact exchange engine. It can convert disposable artifacts such as `Lotus Petal`, `Great Furnace`, spent `Soul-Guide Lantern`, or small Saga artifacts into graveyard artifacts stocked by `Goblin Engineer`. Before activating, compare the artifact sacrificed against future mana, combo access, and board safety; sacrificing `Great Furnace` or `Grindstone` can be correct, but only when the returned artifact is immediately more important. Against graveyard decks or removal-heavy decks, sequence it with `Soul-Guide Lantern`, `Pyroblast`, or redundant artifacts when possible.

- `Fable of the Mirror-Breaker`: use this as the fair-game engine when the hand is not ready to kill quickly. It develops pressure, filters redundant legends or extra artifacts, and can turn later creature copies into tactical pressure or engine value if the rules engine exposes legal copy actions. Hold it less often against fast combo, where mana must stay available for `Pyroblast`, `Red Elemental Blast`, `Mindbreak Trap`, or a faster combo setup. Do not discard unique combo pieces unless recursion, tutor access, or visible matchup pressure makes that exchange better.

- `Agatha's Soul Cauldron`: treat this as a graveyard, counter, and activated-ability engine only when visible legal actions confirm the line. Card text check required for exact ability transfer, counter requirements, and interaction with `Phyrexian Devourer`, `Phyrexian Dragon Engine`, `Goblin Welder`, or `Painter's Servant`. It is strongest when it turns graveyard material into board-based inevitability or disrupts an opposing graveyard card while advancing your own engine. Do not assume a combo outcome without rules-engine actions showing the relevant activation.

- `Lightning Bolt`: use this as cheap stabilization, planeswalker or creature removal when legal, and occasional reach. Against creature pressure, spend it early if it prevents large damage or protects an engine creature from combat pressure. Against combo or control, hold it only if it can pressure life totals, remove a hate creature, or clear a blocker for Constructs. Do not treat `Lightning Bolt` as equivalent to stack interaction; `Pyroblast` and `Red Elemental Blast` have different jobs.

- `Lotus Petal`: spend this only when the tempo matters. It is excellent for turn-one `Painter's Servant`, fast `Goblin Engineer`, protected combo turns, or post-board lock pieces, and it is also a useful artifact for `Goblin Welder`. Avoid cracking it for a low-impact spell when keeping it on the battlefield improves Welder exchanges or future burst mana. With `City of Traitors`, plan the whole turn before using land drops or Petal mana.

- `Simian Spirit Guide`: treat this as hidden burst mana from hand, not a card to preserve for value. Use it when acceleration changes the game state decisively: fast combo, early `Fable of the Mirror-Breaker`, surprise `Pyroblast`/`Red Elemental Blast`, or post-board `Magus of the Moon`/`Blood Moon`. Do not spend it merely to use all mana unless the resulting play is materially stronger than waiting.

- `Soul-Guide Lantern`: use this as maindeck graveyard interaction, a cheap artifact for `Urza's Saga`, and a disposable `Goblin Welder` object. Deploy it early against graveyard-reliant opponents or when Saga needs an artifact count, but consider holding it if the opponent can play around an exposed activation. When it is the only graveyard answer, preserve it for the card or window that matters. Do not sacrifice or exchange it before checking whether the opponent's graveyard is about to enable a stronger line.

- `Ensnaring Bridge`: use this as the emergency stabilizer against creature boards and as a time-buying artifact that can be found or recurred. It is best when your hand can empty quickly through cheap artifacts, blasts, and mana sources. Avoid relying on it against opponents with visible artifact removal unless it buys enough time to assemble `Painter's Servant` plus `Grindstone` or a Welder loop.

- `Phyrexian Devourer`: treat this as a graveyard or activated-ability package card only after checking exact visible legal actions. Card text check required for its activated ability, state-based risk, and `Agatha's Soul Cauldron` use. It is usually not a normal cast-first threat; prefer stocking, recurring, or leveraging it when the engine explicitly supports that line.

- `Phyrexian Dragon Engine`: use this as an artifact creature value target when attrition matters and as a possible `Goblin Engineer` or `Goblin Welder` object. Card text check required for exact graveyard and draw-related text. It is stronger when your hand is depleted or when a recursive artifact threat pressures control decks. Do not run it into exile effects if its graveyard mode is the reason to include it.

- `Chaos Defiler`: treat this as a high-impact artifact creature for longer games and Welder/Engineer setups. Card text check required for exact trigger behavior and target restrictions. Use it when the game has slowed, when a large artifact body or removal-like trigger is worth building toward, or when fair pressure matters more than the immediate `Grindstone` kill. Do not clog early turns around it unless mana and graveyard setup are already stable.

- `Skateboard`: use this only according to visible legal actions because exact card text is uncertain. Card text check required. Treat it as an artifact package card for `Goblin Engineer`, `Goblin Welder`, and `Urza's Saga` planning, but do not assign it a combo, protection, or mana role unless the rules engine exposes that role in the current game.

- `Urza's Saga`: treat this as both a threat and a tutor. It creates a fair-game clock, pressures control, and finds `Grindstone`, `Soul-Guide Lantern`, `Lotus Petal`, or another legal artifact target when chapter ability resolves. Sequence it early when the hand can operate without immediate colored mana, but do not let it strand red spells or force awkward `City of Traitors` turns. Against Wasteland-style pressure in prose context, value getting at least one Construct or tutor trigger before overcommitting.

- `Ancient Tomb`: use this as the fastest route to meaningful two-mana plays. It accelerates `Painter's Servant`, `Grindstone`, `Fable of the Mirror-Breaker`, `Goblin Engineer`, and post-board lock pieces, but the life loss matters against aggressive boards. Avoid repeated pain when `Mountain`, `Great Furnace`, `Lotus Petal`, or `Simian Spirit Guide` can cover the same play without risking the race.

- `City of Traitors`: use this for explosive turns, not casual sequencing. Play it when the current turn or next turn already uses the mana for combo, `Fable of the Mirror-Breaker`, `Chaos Defiler`, or a lock piece. Avoid playing it before a needed land drop unless the immediate action is worth losing future stability.

- `Mountain`, `Great Furnace`, and `Arena of Glory`: preserve red access as the baseline requirement for the deck. `Mountain` is the safest red source, `Great Furnace` adds artifact synergies but is more exposed to artifact interaction, and `Arena of Glory` should be used according to visible legal text; Card text check required for exact ability timing and creature restrictions. Do not sacrifice artifact lands to `Goblin Welder` unless the returned artifact changes the game more than the lost mana.

## Interaction Priorities

- Priority: protect `Painter's Servant` plus `Grindstone` once both are visible, because most wins come from forcing that engine through a narrow exchange. Use `Pyroblast` and `Red Elemental Blast` first on blue counterspells, blue removal, or blue permanent answers that stop the combo; after `Painter's Servant` resolves, those blasts can answer any spell or permanent the rules engine marks as legal blue interaction.

- Priority: remove creatures that either kill quickly, disable artifacts, or attack the engine before spending removal on generic pressure. Use `Lightning Bolt` on small hate creatures, utility creatures, and planeswalkers when legal; post-board use `Abrade` on artifact hate or must-kill artifact engines, and use `Fury` when multiple small creatures make one-for-one removal too slow. Do not fire `Lightning Bolt` at life totals unless the opponent is near lethal, your combo is blocked, or the current turn needs damage to finish a race.

- Priority: exile graveyard resources only when they matter. Use `Soul-Guide Lantern` against visible graveyard combo, recursive threats, or flashback-style value before the opponent gets priority to convert the graveyard into a win. Use `Leyline of the Void` post-board as pregame pressure against graveyard decks, and use `Agatha's Soul Cauldron` exile actions only when the legal target either denies an opposing graveyard card or enables a known creature-ability line. Card text check required before assuming a `Phyrexian Devourer`, `Phyrexian Dragon Engine`, or `Chaos Defiler` ability outcome.

- Priority: counter spell-chain combo differently from fair blue decks. Against storm-style or free-spell combo, preserve `Pyroblast`, `Red Elemental Blast`, and post-board `Mindbreak Trap` for the payoff, protection spell, or stack action the rules engine exposes as decisive; do not spend them on cantrips unless the opponent is constrained and the hand cannot otherwise interact. Against control, spend blasts more aggressively on card advantage, removal aimed at `Painter's Servant`, or a counter war over `Fable of the Mirror-Breaker`, `Urza's Saga`, `Goblin Engineer`, or the combo.

- Priority: use `Pithing Needle`, `Blood Moon`, and `Magus of the Moon` as commitment gates, not reflex plays. Post-board, deploy them when visible lands, permanents, or archetype context show they restrict the opponent more than they restrict your red mana, `Urza's Saga`, `Ancient Tomb`, `City of Traitors`, and artifact plan. If a legal action asks for a named card with `Pithing Needle`, choose only from known visible/public information or matchup policy; do not invent a hidden card.

- Priority: bait interaction with redundant or recoverable artifacts before committing the only combo piece. `Goblin Engineer`, `Goblin Welder`, `Fable of the Mirror-Breaker`, `Urza's Saga` Constructs, `Soul-Guide Lantern`, `Lotus Petal`, and spare `Grindstone` can draw removal or counters while leaving a later `Painter's Servant` safer. Ignore low-impact creatures or nonlethal value spells when a combo turn is close; answer them only if they change the race, attack a required permanent, or invalidate `Ensnaring Bridge`.

- Constraint: the registered main deck has no discard or bounce package. Do not choose discard or bounce lines unless the rules engine exposes them from an external effect, and do not describe absent cards as if they are available interaction.

## Combat And Trading Rules

- Priority: preserve engine creatures over chip damage. Do not attack with `Goblin Welder`, `Goblin Engineer`, or `Painter's Servant` into a visible trade unless the trade protects a stronger line, forces lethal, or the creature is redundant and no longer needed. `Goblin Welder` is usually more valuable untapped than attacking because it threatens artifact exchange, protects against removal when legal, and converts graveyard setup into board presence.

- Priority: use combat to buy time for combo, not to prove dominance. `Urza's Saga` Constructs are the main fair attackers; send them when they pressure life totals without exposing the combo to a crack-back. Hold them back when blocking keeps life above danger thresholds or when `Ensnaring Bridge` requires an empty hand and a low-creature board. If a Construct is your only meaningful blocker, value survival over a small attack unless the opponent is within a two-turn clock.

- Priority: block early against fast creature decks when `Ancient Tomb` life loss is accumulating. Treat 12 life as a caution threshold, 8 life as a survival threshold, and 5 or less as an emergency threshold where every legal block, `Lightning Bolt`, `Fury`, `Abrade`, or `Ensnaring Bridge` line should be checked before advancing a slow engine. Do not take damage to preserve a replaceable token if the next attack plus `Ancient Tomb` activations could lock you out of combo turns.

- Priority: trade expendable bodies before trading unique engines. Reflection tokens from `Fable of the Mirror-Breaker`, `Urza's Saga` Constructs, and artifact creatures that can be recurred by `Goblin Welder` are more acceptable blockers than `Painter's Servant`, `Goblin Welder`, or `Goblin Engineer`. `Phyrexian Dragon Engine`, `Phyrexian Devourer`, `Chaos Defiler`, and `Skateboard` require visible legal text checks before assigning them a combat role; use them as blockers only when the engine confirms the trade or recursion is legal and useful.

- Priority: protect `Painter's Servant` from combat whenever blasts are your protection. After `Painter's Servant` names a color, `Pyroblast` and `Red Elemental Blast` may become broad answers if the rules engine marks targets legal, so keep mana open when attacking or blocking would invite removal. If the opponent can remove `Painter's Servant` mid-combat, avoid combat lines that depend on blasts remaining live unless the engine shows the stack interaction is available.

- Priority: shift combat posture by archetype. Against combo, attack with Constructs and spare creatures to shorten the clock while holding stack interaction. Against control, pressure steadily with `Urza's Saga`, `Fable of the Mirror-Breaker`, and recursive artifacts, but do not overextend into visible sweepers or artifact removal. Against creature decks, defend first, use `Lightning Bolt`, `Fury`, `Abrade`, and `Ensnaring Bridge` to stabilize, then win with combo or a protected Construct clock.

## Selection And Tutor Rules

- Priority: treat `Goblin Engineer` as the main library-selection card. If `Grindstone` is missing and `Painter's Servant` is present or reliably available, put `Grindstone` into the graveyard so `Goblin Welder` or later artifact recursion can convert it into a win. If `Painter's Servant` is missing but the hand already has `Grindstone`, use `Goblin Engineer` for a stabilizing or recursive artifact only when the rules engine confirms the target and later activation are legal.

- Priority: use `Urza's Saga` chapter search to complete the combo before taking generic utility. Find `Grindstone` when `Painter's Servant` is present, find `Soul-Guide Lantern` when visible graveyard pressure matters, and find `Lotus Petal` only when immediate mana is the difference between acting now and passing. Post-board, find `Pithing Needle` only when the engine exposes a naming choice grounded in visible/public information or matchup policy.

- Priority: sequence land drops around selection windows. Play `Urza's Saga` early when the hand can operate through its delayed tutor and Construct pressure; delay it when `Blood Moon` or `Magus of the Moon` is your own plan or when losing Saga chapters would strand the combo. Play `Great Furnace` when artifact count, `Goblin Welder`, or `Goblin Engineer` matters more than insulating mana from artifact removal.

- Priority: discard and treasure choices from `Fable of the Mirror-Breaker` should sculpt toward either protected combo or survival. Discard redundant legends of effect, extra expensive pieces, or artifacts that are better in the graveyard only when your hand still keeps a coherent line. Keep `Pyroblast` and `Red Elemental Blast` against blue decks unless the opponent is visibly not presenting blue interaction and the combo needs velocity.

- Priority: use graveyard selection as a resource, not a dump. `Goblin Engineer`, `Goblin Welder`, `Agatha's Soul Cauldron`, and `Soul-Guide Lantern` all care about graveyard contents in different ways; before exiling or exchanging a card, check whether the card is future recursion fuel, opposing resource denial, or a creature-ability setup. Card text check required before assuming exact activated abilities from `Phyrexian Devourer`, `Phyrexian Dragon Engine`, `Chaos Defiler`, or `Skateboard`.

- Constraint: this list has no true draw spell outside `Fable of the Mirror-Breaker` style filtering and no broad creature or land tutor. Do not invent searches for `Painter's Servant`, `Goblin Welder`, `Goblin Engineer`, `Ancient Tomb`, or `Mountain` unless the rules engine exposes a legal action from a visible effect.

## Priority And Stack Rules

- Priority: pass routine priority when no legal action improves combo protection, survival, or mana use. Do not spend `Pyroblast`, `Red Elemental Blast`, `Lightning Bolt`, `Abrade`, `Mindbreak Trap`, or `Soul-Guide Lantern` just because the engine exposes a legal response; require a visible stack object, graveyard action, creature, artifact, or combo turn that matters.

- Priority: protect `Painter's Servant` and `Grindstone` at stack speed when the win is assembled or nearly assembled. If `Painter's Servant` makes an opposing spell or permanent a legal blast target, use `Pyroblast` or `Red Elemental Blast` on removal, counterspells, or hate that stops the combo. Let low-impact spells resolve when preserving blast mana creates a stronger protected activation.

- Priority: activate `Grindstone` only when the engine shows the target is legal and the activation is worth the exposure. With `Painter's Servant` active, targeting the opponent is the deterministic win plan unless a visible replacement, prevention, graveyard, or library condition makes waiting safer. Without `Painter's Servant`, do not activate `Grindstone` as random pressure unless milling has a visible tactical purpose.

- Priority: use `Goblin Welder` activations as stack-aware protection and conversion. Exchange artifacts when it saves a key artifact from removal, returns `Grindstone`, reuses `Soul-Guide Lantern`, or upgrades an expendable artifact into a decisive permanent. Do not activate into opposing graveyard hate or instant artifact removal unless waiting loses the line.

- Priority: resolve `Goblin Engineer` and `Urza's Saga` tutor choices before committing fragile all-in actions. If the opponent is holding up visible blue interaction, decide whether to bait with `Fable of the Mirror-Breaker`, `Goblin Engineer`, or Saga pressure before casting `Painter's Servant`. Once the combo is protected or the opponent is tapped low, shift from baiting to execution.

- Priority: time graveyard interaction before the opponent converts the graveyard into a stack action. Use `Soul-Guide Lantern`, `Leyline of the Void`, or `Agatha's Soul Cauldron` exile actions when the relevant card is visible and the engine offers a legal window. Avoid exiling your own artifact recursion target unless the same action directly enables a stronger line.

- Priority: treat optional payments and free mana as commitment gates. Use `Lotus Petal`, `Simian Spirit Guide`, `Ancient Tomb`, and `City of Traitors` when the mana enables a protected combo, a stabilizing `Ensnaring Bridge`, a key `Fable of the Mirror-Breaker`, or required interaction this turn. Avoid spending one-shot mana on low-impact plays while holding stack interaction unless tempo is critical.

- Priority: in combat-adjacent windows, check instant interaction before damage. Use `Lightning Bolt`, `Abrade`, or `Fury` before combat damage when a creature threatens lethal, disables artifacts, or changes blocks materially. Otherwise let combat resolve and preserve resources for the combo or the opponent's post-combat stack action.

## Sideboard Map

- Priority: sideboarding must preserve the `Painter's Servant` plus `Grindstone` kill unless the matchup makes survival the only route to a legal turn. Add narrow hate only when it buys time for the combo, protects the combo, or attacks a visible axis the maindeck cannot answer efficiently.

- Priority: `Abrade` is the flexible answer for artifact pressure, small-to-medium creatures, and permanents that threaten `Painter's Servant`, `Grindstone`, `Goblin Welder`, or `Ensnaring Bridge`. It is weak against spell-combo, creature-light control, and matchups where `Pyroblast` or `Red Elemental Blast` already covers the important stack exchanges. Its role changes from removal to artifact-protection when the opponent presents artifact hate or must keep a specific artifact to function.

- Priority: `Fury` is the stabilizer against creature decks that pressure life total, disable blockers, or make `Ensnaring Bridge` too slow. It is weak against low-creature combo, large single threats, and control decks where card quantity matters more than damage prevention. Let the rules engine validate any alternate payment; do not assume a free line unless a legal action is exposed.

- Priority: `Leyline of the Void` is for graveyard engines, graveyard combo, recursive creature plans, and decks where stopping graveyard resources is worth changing mulligan discipline. It is weak when the opponent wins from hand, battlefield, or stack and does not need the graveyard. Its role changes the opening hand evaluation: a legal opener with `Leyline of the Void`, mana, and either combo access or interaction can be stronger than a faster but graveyard-vulnerable hand.

- Priority: `Mindbreak Trap` is for spell-chain combo, fast stack-based turns, and matchups where normal blasts may not answer the decisive spell cleanly. It is weak against fair creature decks, permanent-heavy prison decks, and slow control games where holding `Pyroblast` or `Red Elemental Blast` for a single decisive exchange is better. Treat it as emergency stack containment, not a reason to pass every proactive combo window.

- Priority: `Magus of the Moon` and `Blood Moon` punish nonbasic-heavy mana, land-combo, and control shells that need special lands to cast interaction. They are weak when the opponent uses basic lands well, when the board is already losing to creatures, or when your own `Urza's Saga`, `Great Furnace`, `Ancient Tomb`, `City of Traitors`, or `Arena of Glory` line is more important than mana denial. Their role changes sequencing: fetch no lands are registered, so plan around actual `Mountain` access and deploy important Saga artifacts before committing a Moon effect when possible.

- Priority: `Pithing Needle` is for known activated abilities from public information, visible permanents, or matchup-locked threats that the rules engine exposes through legal naming prompts. It is weak when there is no reliable public name, when the opponent can ignore the named card, or when the name would also disable your own critical `Grindstone` plan. Do not name `Grindstone` in a mirror-like game unless stopping the opponent's visible or publicly known copy is more important than your own activation.

Blue tempo and small-creature pressure
Role cards: 2 Abrade; 3 Fury
Trim roles: 1 Chaos Defiler; 1 Phyrexian Dragon Engine; 1 Skateboard; 1 Soul-Guide Lantern; 1 Agatha's Soul Cauldron

- Role: become a compact combo-control deck that answers early creatures while forcing the opponent to respect `Painter's Servant`, `Grindstone`, and blast protection. Keep `Pyroblast` and `Red Elemental Blast` because blue interaction and `Painter's Servant` make them central. Reduce main-deck emphasis: expensive or text-uncertain artifacts and graveyard utility that do not stabilize the first three turns. Card text check required before treating `Skateboard` as a stabilizer.

Fast graveyard combo or graveyard recursion
Role cards: 4 Leyline of the Void; 2 Mindbreak Trap; 1 Pithing Needle
Trim roles: 2 Lightning Bolt; 1 Ensnaring Bridge; 1 Chaos Defiler; 1 Phyrexian Dragon Engine; 1 Skateboard; 1 Agatha's Soul Cauldron

- Role: use `Leyline of the Void` as the primary pregame axis, then win with the normal combo before the opponent rebuilds. Keep `Soul-Guide Lantern` because redundant graveyard denial matters and `Urza's Saga` can find it. Add role cards: stack containment from `Mindbreak Trap` and activated-ability containment from `Pithing Needle` when public information supports a name. Reduce main-deck emphasis: creature removal and slow value artifacts.

Artifact-centric creatures or permanent pressure
Role cards: 2 Abrade; 3 Fury; 1 Pithing Needle
Trim roles: 2 Red Elemental Blast; 1 Soul-Guide Lantern; 1 Phyrexian Dragon Engine; 1 Chaos Defiler; 1 Skateboard

- Role: defend the battlefield first, then transition back to combo once `Painter's Servant` can survive. `Abrade` answers artifacts and creatures that interfere with `Grindstone`; `Fury` clears creature clusters; `Pithing Needle` covers a public activated ability that removal cannot efficiently answer. Keep some blast density through `Pyroblast` because `Painter's Servant` can convert it into interaction, but do not overload on narrow stack-only cards against nonblue boards.

Greedy nonbasic mana or land-reliant control
Role cards: 2 Magus of the Moon; 1 Blood Moon; 1 Pithing Needle
Trim roles: 1 Soul-Guide Lantern; 1 Ensnaring Bridge; 1 Chaos Defiler; 1 Phyrexian Dragon Engine

- Role: pressure mana while the opponent is still assembling colors, then use `Goblin Engineer`, `Goblin Welder`, `Fable of the Mirror-Breaker`, and normal draws to finish the combo. Prioritize actual `Mountain` before casting `Blood Moon` or `Magus of the Moon`. Delay the Moon plan if `Urza's Saga` is already close to finding `Grindstone` and the opponent is not threatening a faster kill.

Fast spell combo with nonbasic mana
Role cards: 2 Mindbreak Trap; 2 Magus of the Moon; 1 Blood Moon
Trim roles: 2 Lightning Bolt; 1 Ensnaring Bridge; 1 Chaos Defiler; 1 Phyrexian Dragon Engine

- Role: combine stack disruption with mana denial while keeping the fastest `Painter's Servant` plus `Grindstone` hands. Add role cards: `Mindbreak Trap` for decisive spell-chain turns and Moon effects for mana compression. Reduce main-deck emphasis: creature removal and slow expensive threats. Keep blast effects because many spell-combo decks still rely on blue setup or protection, and `Painter's Servant` can make them live interaction.

- Constraint: exact plans are starting templates, not forced runtime actions. If the opponent reveals an unexpected axis, prefer the role package that answers the public information and keep the registered 60-card configuration legal after every sideboard request.

## Matchup Guidance

- Aggro: stabilize before maximizing combo speed when the opponent's visible board can race `Ancient Tomb` damage and artifact setup. Prioritize hands with `Lightning Bolt`, `Fury`, `Abrade`, `Goblin Engineer`, `Goblin Welder`, or a fast `Painter's Servant` plus `Grindstone` line over slow value hands built around `Chaos Defiler` or speculative `Agatha's Soul Cauldron`. Add role cards: `Fury` and `Abrade`. Reduce main-deck emphasis: slow artifacts, graveyard utility when the graveyard is not under pressure, and expensive threats that do not immediately affect combat.

- Control: force the opponent to answer layered threats instead of one all-in combo attempt. Lead with must-answer engines such as `Goblin Engineer`, `Goblin Welder`, `Fable of the Mirror-Breaker`, and `Urza's Saga`, then use `Pyroblast` and `Red Elemental Blast` to protect the decisive `Painter's Servant` or `Grindstone` exchange. Add role cards: `Blood Moon`, `Magus of the Moon`, and `Pithing Needle` when public information identifies vulnerable mana or activated abilities. Reduce main-deck emphasis: `Lightning Bolt`, `Ensnaring Bridge`, and battlefield-only removal unless the control deck has shown creature pressure.

- Combo: identify whether the opponent's kill is stack-based, graveyard-based, permanent-based, or mana-based before committing interaction. Race with the cleanest `Painter's Servant` plus `Grindstone` line when your hand has speed and one protection piece; slow down when `Mindbreak Trap`, `Pyroblast`, `Red Elemental Blast`, `Leyline of the Void`, or `Pithing Needle` attacks the visible axis. Add role cards: `Mindbreak Trap` for spell-chain turns, `Leyline of the Void` for graveyard reliance, `Pithing Needle` for named activated abilities, and Moon effects for fragile nonbasic mana. Reduce main-deck emphasis: `Lightning Bolt`, `Ensnaring Bridge`, and slow value pieces.

- Tempo: trade early resources to keep the combo window open, because tempo decks punish `Ancient Tomb` damage, tapped-out setup, and stranded expensive artifacts. Keep blast-heavy hands against blue tempo, and do not expose `Painter's Servant` without a reason if losing it strands `Grindstone` or blanks protection. Use `Fury`, `Abrade`, and `Lightning Bolt` to clear early threats while `Goblin Engineer` and `Urza's Saga` rebuild. Reduce main-deck emphasis: `Chaos Defiler`, text-uncertain `Skateboard`, and slow graveyard packages when the opponent is attacking mana and life total. Card text check required for `Skateboard`.

- Midrange: become the recursive artifact deck when the opponent has many one-for-one answers. `Goblin Engineer` can stock the graveyard, `Goblin Welder` can convert expendable artifacts into combo pieces, and `Fable of the Mirror-Breaker` can filter redundant blasts or lands into pressure and selection. Do not overcommit both `Painter's Servant` and `Grindstone` into visible removal unless the current turn can activate or protection is available. Add role cards: `Abrade`, `Fury`, `Pithing Needle`, and graveyard hate only when public information shows recursion. Reduce main-deck emphasis: narrow stack interaction if the opponent is not blue or combo-oriented.

- Big mana: pressure mana before the opponent's larger threats invalidate small interaction. Prioritize `Blood Moon`, `Magus of the Moon`, fast combo, and `Pithing Needle` when the rules engine exposes a decisive activated ability. Sequence real `Mountain` access before Moon effects, and weigh whether an active `Urza's Saga` should finish finding `Grindstone` before you turn off your own nonbasic utility. Reduce main-deck emphasis: `Lightning Bolt` and `Fury` unless the opponent has visible creatures that matter.

- Graveyard decks: treat `Leyline of the Void` and `Soul-Guide Lantern` as strategic anchors, not incidental hate. A slower opener with `Leyline of the Void`, stable mana, and either combo access or interaction can be stronger than a faster hand that folds to graveyard acceleration. Keep `Soul-Guide Lantern` because `Urza's Saga` can find it and because redundant graveyard denial may buy the turn needed for `Grindstone`. Add role cards: `Leyline of the Void`, `Mindbreak Trap` when the graveyard deck also chains spells, and `Pithing Needle` when public activated abilities matter. Reduce main-deck emphasis: creature-only removal and expensive value cards.

- Artifact or enchantment decks: answer the permanent that prevents the combo or creates the fastest clock, then return to the normal kill. `Abrade` is the clean flexible role card against artifacts and creatures; `Pithing Needle` is for a public activated ability that removal cannot efficiently answer; `Goblin Welder` can turn artifact exchanges into advantage if graveyards remain usable. Against enchantment-heavy boards, do not assume `Abrade` solves the key card unless the legal action confirms a target. Add role cards: `Abrade`, `Pithing Needle`, and Moon effects only when mana is the weak point.

- Go-wide decks: preserve life total and blockers long enough for combo inevitability. `Fury`, `Lightning Bolt`, and `Abrade` should protect the turns where `Goblin Engineer`, `Goblin Welder`, `Urza's Saga`, or `Fable of the Mirror-Breaker` assemble a kill. `Ensnaring Bridge` matters when hand size can be reduced and the opponent must attack to win, but do not rely on it against noncombat kills or effects that remove artifacts. Add role cards: `Fury` and `Abrade`. Reduce main-deck emphasis: slow single-threat cards and stack-only blasts when the opponent is not blue.

- Single-threat decks: answer or neutralize the one permanent that matters while setting up a protected combo turn. `Ensnaring Bridge` can buy time against combat-centered large threats if hand size cooperates; `Pithing Needle` can stop a public activated ability; `Pyroblast` and `Red Elemental Blast` become universal answers after `Painter's Servant` names blue. Avoid spending `Lightning Bolt` or `Abrade` on low-impact targets when a visible larger threat or enabling permanent is likely to decide the game.

- Burn decks: minimize self-inflicted damage unless the current line materially shortens the clock. `Ancient Tomb`, `City of Traitors`, `Lotus Petal`, and `Simian Spirit Guide` can enable fast combo, but life total is a real resource against direct damage. Prefer hands that either combo quickly or interact while using `Mountain` and artifact mana efficiently. Add role cards: `Fury` only for creature-heavy burn variants and `Abrade` only when creatures or artifacts are visible. Reduce main-deck emphasis: slow value engines that do not affect life total or the immediate kill.

- Removal-heavy decks: demand multiple answers by splitting threats across creatures, artifacts, lands, and graveyard recursion. Do not treat the first `Painter's Servant` as disposable if `Grindstone` is already present and activation is near; do treat extra artifact bodies, tokens, and expendable artifacts as fuel for `Goblin Welder` when graveyards are accessible. `Agatha's Soul Cauldron` can matter in attrition if its legal actions and visible exiled cards support a line, but do not assume hidden text or unavailable abilities. Add role cards: `Pithing Needle` for public removal engines or planeswalker-like activated abilities, `Abrade` for opposing hate artifacts, and Moon effects when the removal deck's mana is greedy.

## Specific Matchup Notes

- General/archetype-only: revealed cards override these assumptions, because Veles must choose from legal actions, visible board state, and public information before applying matchup heuristics. When the opponent's plan is unclear, prioritize lines that keep `Painter's Servant` plus `Grindstone` available, preserve at least one interactive card, and avoid exposing both combo pieces to visible removal unless activation or protection is legal now.

- Blue interaction: treat `Pyroblast` and `Red Elemental Blast` as premium protection before and after `Painter's Servant` resolves. Likely sideboarding emphasizes `Mindbreak Trap` against spell-chain turns, `Pithing Needle` for public activated abilities, and `Abrade` only when hate artifacts or creatures are visible. Priority targets are opposing counters, stack-based combo payoffs, and permanents that stop `Grindstone` activation.

- Nonblue fair decks: lean on recursion, tokens, and artifact exchanges instead of spending every resource on the first combo attempt. `Goblin Engineer`, `Goblin Welder`, `Fable of the Mirror-Breaker`, and `Urza's Saga` make removal-heavy games winnable if the pilot does not trade all artifacts too early. Likely sideboarding emphasizes `Abrade`, `Fury`, `Pithing Needle`, and Moon effects when mana is greedy.

- Fast creature decks: protect life total before treating the combo as inevitable. `Lightning Bolt`, `Fury`, `Abrade`, and `Ensnaring Bridge` should buy enough time for `Urza's Saga`, `Goblin Engineer`, or `Goblin Welder` to assemble a deterministic kill. Priority targets are lethal attackers, creatures that invalidate `Ensnaring Bridge`, and hate permanents that prevent `Grindstone` or artifact recursion.

- Graveyard decks: mulligan and sideboard as though graveyard access is the first battlefield. `Leyline of the Void` and `Soul-Guide Lantern` are high-value anchors, while `Mindbreak Trap` matters when the opponent also wins by chaining spells. Do not cut `Soul-Guide Lantern` casually because `Urza's Saga` can find it and `Goblin Engineer` can make graveyard texture relevant.

- Big-mana or nonbasic-heavy decks: deploy `Blood Moon` or `Magus of the Moon` only after checking your own `Mountain` access and whether `Urza's Saga` should first search. Priority targets are mana engines, public activated abilities, and the first permanent that outscales `Lightning Bolt` or `Fury`. `City of Traitors`, `Ancient Tomb`, and `Lotus Petal` can justify fast Moon turns when waiting gives the opponent a stronger board.

- Combo mirrors and fast combo: force a commitment only when the legal action window supports a protected kill or meaningful disruption. `Mindbreak Trap`, `Pyroblast`, `Red Elemental Blast`, `Pithing Needle`, `Leyline of the Void`, and `Soul-Guide Lantern` each attack different axes, so choose hate based on revealed cards rather than archetype label alone.

## Risk Summary

- Mana risk: `Ancient Tomb`, `City of Traitors`, `Lotus Petal`, and `Simian Spirit Guide` create explosive starts but punish slow or uncertain lines. Avoid spending temporary mana on low-impact setup if it strands `Painter's Servant`, `Grindstone`, `Goblin Engineer`, or protection for the actual kill turn.

- Matchup risk: sideboard cards are narrow if chosen from archetype memory instead of public information. `Leyline of the Void`, `Mindbreak Trap`, `Blood Moon`, `Magus of the Moon`, `Abrade`, `Fury`, and `Pithing Needle` should enter for a visible axis, not because the opponent merely resembles a broad category.

- Draw risk: hands with only payoff, only recursion, or only blasts can look functional while failing to progress. Mulligan or sequence toward a real engine: `Painter's Servant` plus `Grindstone`, `Urza's Saga` into artifact access, `Goblin Engineer` plus `Goblin Welder`, or `Fable of the Mirror-Breaker` filtering into those pieces.

- Over-sideboarding risk: cutting too many main-deck artifacts weakens `Goblin Welder`, `Goblin Engineer`, `Urza's Saga`, and `Agatha's Soul Cauldron`. Preserve enough artifacts and combo density that post-board games still end through `Grindstone` rather than becoming unfocused red midrange.

- Graveyard risk: `Goblin Engineer`, `Goblin Welder`, `Agatha's Soul Cauldron`, `Soul-Guide Lantern`, and opposing graveyard hate can conflict. Before using a graveyard action, verify whether the graveyard is a resource, a liability, or a hate target in the current visible state.

- Sweeper/removal risk: exposing multiple fragile creatures into visible removal can collapse both combo and recursion. Hold extra `Painter's Servant`, `Goblin Welder`, or `Goblin Engineer` when one copy already supports the current line unless a same-turn activation or protected follow-up is legal.

- Closer risk: `Chaos Defiler`, `Phyrexian Dragon Engine`, `Fable of the Mirror-Breaker`, and constructs from `Urza's Saga` can win attrition games, but they should not distract from a live `Painter's Servant` plus `Grindstone` kill. Card text check required for `Skateboard`; use only legal actions and visible text until verified.

- Interaction risk: `Pyroblast` and `Red Elemental Blast` become broader with `Painter's Servant`, but before that they may be conditional. Do not assume they answer a nonblue object unless the rules engine exposes the legal target.

- Sequencing risk: activating `Grindstone`, welding artifacts, searching with `Urza's Saga`, or casting Moon effects can change available mana and future legal actions. Choose the order that preserves the current commitment gate, especially when `Painter's Servant` is exposed or temporary mana is involved.

## Test Feedback Checklist

- Match result: identify the deciding axis before judging individual plays. Was the game lost or won through `Painter's Servant` plus `Grindstone`, `Urza's Saga` constructs, `Goblin Engineer`/`Goblin Welder` recursion, `Fable of the Mirror-Breaker` attrition, sideboard hate, or failure to stabilize?

- Mulligans: record whether opening hands contained a real plan instead of loose pieces. Flag hands that kept only blasts, only mana, only recursion, or only expensive artifacts without `Painter's Servant`, `Grindstone`, `Urza's Saga`, `Goblin Engineer`, `Goblin Welder`, or `Fable of the Mirror-Breaker` to convert them.

- Mana: check whether `Ancient Tomb`, `City of Traitors`, `Lotus Petal`, `Simian Spirit Guide`, `Great Furnace`, `Arena of Glory`, and `Mountain` supported the chosen line. Note every game where temporary mana was spent before a protected combo turn, where `City of Traitors` sequencing cost a key follow-up, or where Moon effects constrained our own actions.

- Velocity: evaluate whether early turns advanced a kill or a lock. A good start should assemble `Painter's Servant` plus `Grindstone`, set up `Urza's Saga`, put a target in the graveyard with `Goblin Engineer`, deploy `Fable of the Mirror-Breaker`, or establish hate such as `Soul-Guide Lantern`, `Leyline of the Void`, `Pithing Needle`, `Blood Moon`, or `Magus of the Moon`.

- Engines: record whether `Goblin Engineer`, `Goblin Welder`, `Agatha's Soul Cauldron`, `Fable of the Mirror-Breaker`, and `Urza's Saga` generated actual decisions and material advantage. Flag games where an engine was deployed but never activated, protected, copied, searched from, or used to pressure the opponent.

- Interaction: review every `Pyroblast`, `Red Elemental Blast`, `Lightning Bolt`, `Abrade`, `Fury`, `Mindbreak Trap`, and `Pithing Needle` decision. Mark whether the action stopped a decisive opposing line, protected the combo, preserved life total, or was spent on a low-impact object while a stronger public threat remained.

- Sideboard: verify that sideboard cards matched public and matchup-relevant axes. `Leyline of the Void` should matter against graveyard reliance, `Mindbreak Trap` against spell-chain turns, `Abrade` against creatures or artifacts, `Fury` against creature pressure, `Blood Moon` and `Magus of the Moon` against nonbasic-heavy mana, and `Pithing Needle` against a named activated ability.

- Closing: check whether the pilot recognized deterministic or near-deterministic closing windows. Misses include passing with active `Painter's Servant` plus `Grindstone`, delaying `Urza's Saga` search without a reason, failing to protect a combo action with `Pyroblast` or `Red Elemental Blast`, or choosing attrition when a legal kill was visible.

- Role: determine whether the pilot chose combo, control, prison, or attrition correctly for the matchup and board. Flag role drift where `Chaos Defiler`, `Phyrexian Dragon Engine`, constructs, or `Fable of the Mirror-Breaker` distracted from a safer combo kill, or where combo commitment ignored lethal creature pressure.

- Mistakes and stranded cards: list cards that sat unused despite legal windows, especially `Agatha's Soul Cauldron`, `Ensnaring Bridge`, `Phyrexian Devourer`, `Phyrexian Dragon Engine`, `Chaos Defiler`, `Skateboard`, and sideboard cards. Card text check required for `Skateboard`; judge it only from legal actions and visible rules-engine output.

- Overperformers and underperformers: identify which exact cards caused wins, bought time, or clogged hands. Separate power-level concerns from pilot errors, mana constraints, matchup mismatch, and rules-engine uncertainty.

## First Tuning Questions

- Combo density: should the deck keep exactly 4 `Painter's Servant` and 2 `Grindstone`, or did games show too many hands with one half and no reliable access through `Urza's Saga`, `Goblin Engineer`, or `Goblin Welder`?

- Artifact package: did 3 `Agatha's Soul Cauldron`, 1 `Phyrexian Devourer`, 1 `Phyrexian Dragon Engine`, 1 `Skateboard`, 1 `Soul-Guide Lantern`, and 1 `Ensnaring Bridge` create useful searchable texture, or did too many singleton artifacts become stranded without clear legal impact?

- Mana base: did 4 `Ancient Tomb`, 1 `City of Traitors`, 2 `Great Furnace`, 4 `Urza's Saga`, 1 `Arena of Glory`, and 9 `Mountain` balance speed, colored mana, and post-board Moon effects, or did the deck lose to self-inflicted sequencing and damage?

- Temporary mana: did 2 `Lotus Petal` and 2 `Simian Spirit Guide` produce meaningful turn-one or protected combo turns, or did they reduce attrition quality in games decided by removal and recursion?

- Blue interaction: were 4 `Pyroblast` and 2 `Red Elemental Blast` excellent often enough in Legacy games, or did nonblue matchups expose too many conditional interaction cards before `Painter's Servant` resolved?

- Removal spread: did 2 `Lightning Bolt`, 2 `Abrade`, and 3 `Fury` cover creature pressure after sideboarding, or does the deck need a different balance between cheap removal, artifact answers, and card economy?

- Prison plan: did `Ensnaring Bridge`, `Blood Moon`, and `Magus of the Moon` win games that the combo could not, or did prison cards conflict with `Urza's Saga`, artifact recursion, hand size, or red mana requirements?

- Graveyard plan: did 4 `Leyline of the Void` plus `Soul-Guide Lantern` meaningfully improve graveyard matchups, or did Leyline-heavy hands lack enough pressure, mana, or combo access to close before the opponent rebuilt?

- Fast-combo plan: did 2 `Mindbreak Trap` create enough free interaction, or were losses caused by missing discard-proof pressure, slow clocks, or spending blasts on the wrong stack objects?

- Attrition closers: did `Chaos Defiler`, `Phyrexian Dragon Engine`, `Fable of the Mirror-Breaker`, and `Urza's Saga` close removal-heavy games, or were wins still mostly dependent on resolving `Grindstone`?

- Role conflict: did post-board games become unfocused between combo, prison, and creature-control plans? If so, define which matchups should emphasize `Painter's Servant` plus `Grindstone`, which should emphasize Moon effects, and which should emphasize removal plus engines.

- Sideboard slots: did `Pithing Needle` have enough high-impact named targets, or would the sideboard benefit more from additional copies of effects already represented by `Abrade`, `Fury`, `Mindbreak Trap`, `Leyline of the Void`, `Blood Moon`, or `Magus of the Moon`?
