# Strategy Specifications
## Deck Name And Archetype

- Identity: LED Dredge is a Legacy graveyard-combo deck built to convert discard, draw, and dredge replacement effects into a graveyard engine, then win through Dread Return payoffs, Bridge from Below token pressure, Cabal Therapy disruption, and recursive pressure from Narcomoeba and Poxwalkers. Treat Forge/Veles legal actions as binding at runtime: do not assume dredge replacement, flashback, sacrifice, or trigger choices are available unless the rules engine exposes them.

- Validation: The registered configuration is 60 main-deck cards and 15 sideboard cards, which satisfies the active Legacy validation contract supplied for this guide. The registered main deck is 4 Lion's Eye Diamond; 3 Poxwalkers; 4 Otherworldly Gaze; 4 Narcomoeba; 2 Ox of Agonas; 1 Thassa's Oracle; 3 Golgari Thug; 1 Underground Sea; 1 Scalding Tarn; 3 Volcanic Island; 1 Island; 1 Misty Rainforest; 3 Bridge from Below; 4 Faithless Looting; 4 Stinkweed Imp; 4 Cabal Therapy; 2 Breakthrough; 3 Dread Return; 4 Golgari Grave-Troll; 1 Polluted Delta; 1 Careful Study; 4 Cephalid Coliseum; 2 Flooded Strand. The sideboard is 4 Unmask; 4 Into the Flood Maw; 3 Siege Smash; 4 Leyline of the Void.

- Format status: This guide assumes Legacy play with the current registered list passing validation, but it does not independently certify ban-list legality, exact Oracle text, replacement-effect timing, or card-specific implementation status inside Forge. When legal actions disagree with strategic expectations, follow the legal actions and record the discrepancy rather than forcing a planned line.

- Archetype tags: Use combo and graveyard as the primary runtime tags. The deck is not a fair midrange deck and should not spend early turns trading resources unless that line protects a near-term graveyard engine, preserves a crucial payoff, or buys time through visible necessity.

- Stock/rogue/hybrid status: Classify the deck as a stock Legacy LED Dredge shell with a hybrid finish package. Lion's Eye Diamond, Faithless Looting, Breakthrough, Careful Study, Cephalid Coliseum, Golgari Grave-Troll, Stinkweed Imp, Golgari Thug, Narcomoeba, Bridge from Below, Cabal Therapy, and Dread Return form the familiar dredge engine. Poxwalkers, Ox of Agonas, and Thassa's Oracle create a registered-deck-specific angle that requires careful runtime validation rather than autopilot assumptions.

- Role concern: Pilot the deck as the proactive engine in most unknown pairings. The first job is to assemble a hand that can place a dredger or graveyard engine card into the graveyard and immediately convert a draw event into dredge volume. The second job is to turn that graveyard volume into battlefield material, Cabal Therapy information, and a deterministic or resilient Dread Return line when legal.

- Mana concern: The mana base is narrow and action-oriented, with Cephalid Coliseum, Volcanic Island, Underground Sea, Island, Scalding Tarn, Misty Rainforest, Polluted Delta, and Flooded Strand supporting blue and red setup spells. Fetchland decisions should prioritize castable Faithless Looting, Otherworldly Gaze, Breakthrough, Careful Study, and Cephalid Coliseum activation lines exposed by the engine, not long-game color perfection.

- Legality concern: Lion's Eye Diamond creates powerful sequencing with discard and draw spells, but decisions involving mana ability timing, hand discard, flashback, and draw replacement must be chosen only from visible legal action IDs. Do not assume a classic line is legal if the current prompt has moved past the correct priority window.

- Opponent information status: No opponent deck, matchup, or metagame target is supplied for this section. Default to unknown-opponent Legacy assumptions: expect some mix of fast combo, graveyard hate, stack interaction, permanent disruption, and creature pressure, but do not name or play around a specific card unless it is public, revealed, logged, or supplied by the matchup section.

- Runtime posture: Use this specification to bias low-cost model calls toward explosive graveyard setup, disciplined mulligans, and legal deterministic execution after commitment. Use stronger reasoning for mulligans, Dread Return commitment, Cabal Therapy naming from partial information, sideboarding, and any line that risks losing the graveyard engine to visible interaction or a failed rules-engine assumption.

## Thesis

- Assemble graveyard velocity first: LED Dredge converts early discard, draw, and dredge replacement choices into a graveyard large enough to produce Narcomoeba, Bridge from Below tokens, Poxwalkers recursion, Cabal Therapy flashback pressure, and Dread Return access. Prioritize opening sequences that put Golgari Grave-Troll, Stinkweed Imp, or Golgari Thug into the graveyard before or during the first major draw effect.

- Win by making the graveyard into the hand: the deck's strongest games use Faithless Looting, Breakthrough, Careful Study, Otherworldly Gaze, Cephalid Coliseum, and Lion's Eye Diamond to see many replacement-dredge events, then convert the resulting graveyard into creatures, disruption, and a payoff. The cleanest finish is Dread Return for Thassa's Oracle when the library state and legal trigger text support it; fallback finishes use Bridge from Below tokens, recurring Poxwalkers, Narcomoeba pressure, Ox of Agonas reloads, and Cabal Therapy to strip interaction.

- Do not pilot this as a fair blue-red spell deck: Volcanic Island, Underground Sea, Island, and fetchlands exist to enable explosive setup, not to support long attrition. Avoid spending early turns making low-impact land drops and passing when a legal line can put a dredger into the graveyard and immediately convert a draw into engine volume.

- Prioritize commitment discipline: Lion's Eye Diamond plus Breakthrough, Faithless Looting, Careful Study, Otherworldly Gaze, or Cephalid Coliseum can create decisive turns, but legal action timing matters. Commit when the visible line produces dredge volume, bodies, or a Dread Return path; wait or choose a smaller setup line when the hand would be discarded without a dredger, payoff, or follow-up action visible.

## Role Package

- Threats: Narcomoeba, Poxwalkers, Bridge from Below tokens, Ox of Agonas, and Thassa's Oracle are the cards that actually convert engine progress into victory pressure. Narcomoeba supplies free bodies for Cabal Therapy and Dread Return, Poxwalkers turns non-hand casting into recurring material when its text is legally implemented, Bridge from Below turns creature sacrifices into battlefield volume when it remains active, Ox of Agonas can reload and pressure, and Thassa's Oracle is the compact deterministic payoff only when the library and trigger state make it valid.

- Payoffs: Dread Return is the main payoff bridge from graveyard volume to a game-ending or game-locking creature. Use it only after confirming legal sacrifice bodies and a target exposed by the rules engine. Thassa's Oracle is the high-leverage target when library count and devotion-style resolution conditions are favorable; Ox of Agonas is the reload target when more dredging, cards, or battlefield pressure are needed.

- Engines: Golgari Grave-Troll, Stinkweed Imp, and Golgari Thug are the dredge core, with Golgari Grave-Troll usually the highest-volume replacement when multiple dredgers are available. Bridge from Below, Narcomoeba, Poxwalkers, Cabal Therapy, and Dread Return form the graveyard-to-battlefield engine once dredging starts.

- Velocity: Faithless Looting, Breakthrough, Careful Study, Otherworldly Gaze, Cephalid Coliseum, and Lion's Eye Diamond are the acceleration package. Faithless Looting and Careful Study are controlled setup tools, Breakthrough and Cephalid Coliseum are burst tools, Otherworldly Gaze sets up graveyard and draw quality, and Lion's Eye Diamond provides explosive mana plus discard when the visible sequence benefits from emptying the hand.

- Interaction: Cabal Therapy is the maindeck interaction and sacrifice outlet, with its value tied to public information, revealed cards, matchup guidance, or visible forced-protection needs. Unmask is the sideboard hand-interaction module for matchups where protecting the engine or breaking a faster plan matters.

- Protection: Protection is proactive rather than defensive: Cabal Therapy and Unmask remove opposing interaction, while fast dredge volume reduces the time opponents have to deploy hate. Into the Flood Maw and Siege Smash are sideboard tools for opposing permanents or pressure, but exact tactical use requires card text and legal target checks at runtime.

- Recursion: Poxwalkers, Dread Return, Ox of Agonas, Faithless Looting flashback, and graveyard-cast Cabal Therapy are the recursion package. Treat every recursion action as rules-engine-gated; choose it only when the legal prompt exposes the spell, target, sacrifice, or cost choice.

- Mana: Lion's Eye Diamond, Cephalid Coliseum, Volcanic Island, Underground Sea, Island, Scalding Tarn, Misty Rainforest, Polluted Delta, and Flooded Strand support blue-red setup and burst activation turns. Fetch for colors that cast the current legal setup spell or enable Cephalid Coliseum threshold turns, not for abstract long-game flexibility.

- Sideboard modules: Unmask adds proactive protection and disruption, Into the Flood Maw adds a bounce-style answer if its text and legal targets confirm that role, Siege Smash needs a card text check before exact use, and Leyline of the Void is the graveyard-hate mirror or graveyard-combo module that must be valued heavily in opening-hand and pregame decisions when boarded.

## Primary Win Conditions

- Thassa's Oracle via Dread Return is the cleanest combo finish when the graveyard engine has reduced the library enough for the legal Thassa's Oracle trigger to win. Setup requires a dredger such as Golgari Grave-Troll, Stinkweed Imp, or Golgari Thug in the graveyard, velocity from Faithless Looting, Breakthrough, Careful Study, Otherworldly Gaze, Cephalid Coliseum, or Lion's Eye Diamond, at least three sacrificable creatures from Narcomoeba, Bridge from Below tokens, Poxwalkers, or other legal bodies, and Thassa's Oracle accessible in graveyard or another legal zone for Dread Return. Execute only after the rules engine exposes Dread Return as legal, the sacrifice choices are visible, and Thassa's Oracle is a legal target. Prioritize this line when the opponent has a short clock, the library count is already low, Cabal Therapy or Unmask has cleared relevant interaction, or waiting gives graveyard hate and stack interaction more time.

- Bridge from Below pressure wins when repeated creature sacrifices generate enough battlefield material to attack through fair defenses. Setup by dredging Bridge from Below, Narcomoeba, Cabal Therapy, Dread Return, and dredgers, then use Cabal Therapy flashback and Dread Return costs to sacrifice your own creatures while Bridge from Below remains active under the rules engine. Execute by stripping interaction with Cabal Therapy when information supports a name, converting Narcomoeba and Poxwalkers into sacrifice material, and attacking with the resulting creature tokens over one or two combat steps. Prioritize this line when Thassa's Oracle is unavailable, library count is too high for a safe Oracle finish, or visible board pressure can be beaten by producing multiple bodies.

- Ox of Agonas reload wins when the first dredge burst creates material but not a lethal Dread Return finish. Setup by placing Ox of Agonas in the graveyard with enough graveyard resources and legal costs exposed by the engine, then choose the Ox of Agonas line if it produces new draw events that can become dredges. Execute by using Ox of Agonas as a Dread Return target or other legal graveyard-cast route only when its prompt and costs are visible; then replace draws with the highest useful dredgers, often Golgari Grave-Troll before Stinkweed Imp before Golgari Thug. Prioritize this line when the hand is empty from Lion's Eye Diamond or Breakthrough, the graveyard has dredgers but lacks a payoff configuration, or a second wave is safer than committing Thassa's Oracle into uncertainty.

## Secondary Win Conditions

- Narcomoeba and Poxwalkers can become a fallback clock when combo conversion stalls. Narcomoeba is free battlefield material from dredge chains when its trigger resolves legally, while Poxwalkers requires a card text check at runtime before relying on recursion from non-hand casting. Use these bodies to pressure planes-free life totals, flash back Cabal Therapy, and enable Dread Return rather than preserving them as traditional blockers unless survival is the immediate issue.

- Cabal Therapy creates a soft protection lock when the graveyard produces multiple sacrifice bodies. Use public information, revealed hands, matchup guidance, previous actions, or sideboard context to name a card; do not invent hidden cards or assume a specific answer. The first Cabal Therapy can clear stack interaction or graveyard hate before committing Dread Return, and flashback Cabal Therapy can turn Narcomoeba, Bridge from Below tokens, or Poxwalkers into both disruption and engine fuel.

- Hardcast setup spells can rebuild when explosive graveyard lines are disrupted. Volcanic Island, Underground Sea, Island, and fetchlands support Faithless Looting, Careful Study, Otherworldly Gaze, and Breakthrough as legal hand-based ways to restart dredging after the first graveyard is checked. Prefer controlled discard-and-draw spells over all-in Lion's Eye Diamond lines when the current hand still contains the only payoff, the only dredger, or sideboard interaction needed next turn.

- Post-board pressure can come from Leyline of the Void backed by normal dredge if the matchup is graveyard-dependent. Leyline of the Void is not a damage source, but it can buy time for Bridge from Below pressure or a Dread Return finish when boarded and present in the opener. Into the Flood Maw and Siege Smash require card text and legal target checks before assigning them a win-path role.

## Emergency Lines

- Behind on life, choose the line that changes the battlefield or wins immediately instead of taking a slow sculpting turn. If Dread Return for Thassa's Oracle is legal and the trigger condition is favorable, commit; otherwise use Bridge from Below, Narcomoeba, Poxwalkers, and Cabal Therapy flashback to create blockers or attackers that shorten the race. Do not spend a low-life turn on Otherworldly Gaze or a small Faithless Looting line if a legal dredge burst, Ox of Agonas reload, or Dread Return line is available and materially affects survival.

- Behind on board, convert graveyard material into bodies before preserving resources. Narcomoeba triggers, Bridge from Below token production, and Poxwalkers recursion are more valuable than perfect hand texture when opposing attackers threaten lethal. Use Cabal Therapy flashback carefully: sacrifice creatures for disruption when it also advances Bridge from Below or clears a lethal answer, but avoid shrinking your own defense if the visible combat math requires bodies.

- Behind on cards or with an empty hand, lean into graveyard-cast and flashback resources. Faithless Looting from graveyard, Cabal Therapy from graveyard, Dread Return, Ox of Agonas, Poxwalkers, and dredge replacement effects let the deck function without normal hand size. Lion's Eye Diamond is acceptable when the visible follow-up uses mana immediately or the discarded hand becomes engine material; it is dangerous when it discards the only legal setup without a dredger or payoff.

- Behind on mana, prioritize zero- and one-mana engine actions over speculative land sequencing. Lion's Eye Diamond, Otherworldly Gaze, Faithless Looting, Careful Study, and fetchland access to Volcanic Island, Underground Sea, or Island can start the engine with minimal mana. Cephalid Coliseum should be preserved for threshold-style burst turns when possible, but use it as a mana source if the legal sequence otherwise fails to begin.

- If graveyard recursion is removed or suppressed, rebuild from hand and sideboard interaction rather than forcing illegal graveyard lines. Cast setup spells to place a new dredger, use Unmask or Cabal Therapy when legal to clear the next obstacle, and use Into the Flood Maw or Siege Smash only if card text and legal targets confirm they answer the visible problem.

- If Thassa's Oracle is removed, unavailable, or unsafe, switch to Bridge from Below pressure, Ox of Agonas reload, and creature attacks. If Bridge from Below is gone, use Narcomoeba, Poxwalkers, Ox of Agonas, and hardcast or flashback spells to assemble Dread Return for a non-Oracle value line only when the target and sacrifice costs are clearly legal.

## Resource Model

- Life: Treat life as the clock that decides whether to sculpt or commit. Fetch only for the color or land type the visible line needs, and prefer a winning Dread Return, Ox of Agonas reload, or Bridge from Below body-production turn over a slow setup spell when opposing attacks threaten lethal soon.

- Hand: Treat hand size as expendable, but protect unique payoff and interaction pieces until the rules engine exposes a legal way to use or discard them profitably. Lion's Eye Diamond and Breakthrough can turn a full hand into a graveyard, but do not empty the hand if it contains the only Thassa's Oracle, Dread Return, sideboard answer, or dredger without a visible draw/discard follow-up.

- Mana: Spend mana on draw/discard events that can become dredges, not on preserving normal card flow. Faithless Looting, Careful Study, Otherworldly Gaze, Breakthrough, Cephalid Coliseum, and legal graveyard actions are the deck's mana sinks; sequence them so the first draw event has Golgari Grave-Troll, Stinkweed Imp, or Golgari Thug available if possible.

- Board: Value battlefield permanents mainly as sacrifice fodder and combo material. Narcomoeba, Bridge from Below tokens, and Poxwalkers should usually convert into Cabal Therapy flashback or Dread Return costs, but keep bodies back when the visible combat step requires blockers to survive. Card text check required for Poxwalkers recursion before relying on it as repeatable material.

- Graveyard: Treat the graveyard as the primary hand and engine zone. Dredgers, Cabal Therapy, Dread Return, Bridge from Below, Ox of Agonas, Narcomoeba triggers, and possible Poxwalkers recursion all gain value there; protect this zone from visible hate, and prioritize Unmask or Cabal Therapy when a known or likely disruption card must be cleared before committing.

- Exile: Treat exile as the resource-loss zone unless a legal action explicitly says otherwise. If Golgari Grave-Troll, Stinkweed Imp, Dread Return, Bridge from Below, Thassa's Oracle, or Ox of Agonas is exiled, update the win plan immediately instead of assuming normal graveyard conversion still works.

- Lands: Treat lands as colored access plus Cephalid Coliseum burst capacity. Volcanic Island casts red setup, Underground Sea supports blue and black actions, Island is stable blue, and fetchlands select the color needed for the current line. Cephalid Coliseum is both a land and an engine card, so preserve it for a legal burst activation when possible.

- Sacrifice fodder: Spend sacrifice creatures when the sacrifice advances a decisive action. Cabal Therapy flashback is strongest with information or a specific card to clear, while Dread Return asks whether the target wins, reloads, or stabilizes enough to justify losing three bodies.

- Tempo: Prefer explosive turns when waiting exposes the graveyard to hate or the opponent's clock is short. Prefer incremental setup when the hand has multiple engines, the opponent is not pressuring, or visible interaction makes a blind Dread Return line fragile.

- Information: Use revealed hands, public actions, known sideboard context, and previous decisions to name Cabal Therapy. Do not infer exact hidden cards beyond public information; when no reliable name exists, value Cabal Therapy flashback more as a sacrifice and Bridge from Below enabler than as guaranteed disruption.

- Sideboard bullets: Use Unmask as protection before fragile combo commitments, Leyline of the Void as opening-hand graveyard pressure against opposing graveyard plans, and Into the Flood Maw or Siege Smash only after card text and legal targets confirm they answer the visible permanent or spell problem. Card text check required for Into the Flood Maw and Siege Smash.

## Mana Guide

- Utility-land sequencing: explicitly track `Bridge from Below`, `Flooded Strand` 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.

- Color priority: Secure blue or red first for the opening engine spell, then black when Cabal Therapy, Dread Return lines, or Unmask plans matter. Volcanic Island is the default fetch target for Faithless Looting plus blue setup access, Underground Sea is preferred when Cabal Therapy or black interaction is central, and Island is safest when only blue actions are needed or life preservation matters.

- Land sequencing: Lead on the land that casts the current turn's setup spell without revealing unnecessary future colors. Use fetchlands after deciding whether the turn needs Faithless Looting, Careful Study, Otherworldly Gaze, Breakthrough, Cabal Therapy, or sideboard interaction; avoid fetching before a draw spell if the legal line may change based on the cards or dredges seen.

- Cephalid Coliseum timing: Preserve Cephalid Coliseum for a legal draw-discard burst when the graveyard is already stocked and the engine can replace draws with dredge. Use Cephalid Coliseum as ordinary mana only when delaying prevents the deck from starting or when the current legal action requires that mana to continue.

- Lion's Eye Diamond timing: Use Lion's Eye Diamond when the visible line converts the discarded hand and mana immediately. Common safe patterns include enabling Faithless Looting from graveyard, paying for a legal Ox of Agonas or Dread Return-adjacent line if exposed, or turning Breakthrough into an all-in dredge burst; avoid cracking it before choosing targets, modes, or spells if the discarded hand contains required choices that are not yet committed.

- Keep and mulligan mana rules: Keep hands that have at least one functional engine path: land plus Faithless Looting, Careful Study, Otherworldly Gaze, or Breakthrough with a dredger/discard plan; or Lion's Eye Diamond plus a visible spell sequence that discards and draws. Mulligan hands with mana but no dredger, no enabler, and no sideboard bullet in a matchup where the sideboard bullet is the reason to keep.

- Play-land-before-draw rule: Play a land before drawing when the current hand already identifies the exact spell to cast this turn and the land choice will not depend on the draw. Hold fetchlands or land drops until after Faithless Looting, Careful Study, Otherworldly Gaze selection, or dredge resolution when the next card identities could determine whether the turn needs red, blue, black, Cephalid Coliseum, or a second land.

- Post-board mana rule: Do not let sideboard cards distort the engine unless their legal action solves the visible problem. Unmask may reduce hand resources without mana, Leyline of the Void asks for opening-hand evaluation, and Into the Flood Maw or Siege Smash should be sequenced only after card text, color, cost, and legal target checks confirm the mana investment advances the current game plan.

## Mulligan Guide

- Strong keep: Keep any hand with a land, a discard/draw enabler, and Golgari Grave-Troll, Stinkweed Imp, or Golgari Thug. Volcanic Island plus Faithless Looting plus Golgari Grave-Troll is excellent; Island or Underground Sea plus Careful Study plus Stinkweed Imp is also a real start because the first draw events can become dredges.

- Strong explosive keep: Keep Lion's Eye Diamond hands only when the visible sequence converts the discarded hand into immediate engine action. Lion's Eye Diamond plus Faithless Looting, Breakthrough, or graveyard Faithless Looting access is powerful; do not keep Lion's Eye Diamond as generic mana when the hand lacks dredger, draw spell, or a legal follow-up.

- Medium keep: Keep slower hands with Otherworldly Gaze plus a dredger when mana casts it and the matchup is not presenting immediate lethal pressure. Otherworldly Gaze is selection and graveyard setup, but it is weaker than Faithless Looting or Careful Study if it cannot place a dredger where the next draw can use it.

- Risky keep: Keep Cephalid Coliseum-only hands only when they have a credible path to threshold or another castable setup spell. Cephalid Coliseum is a payoff land, not a complete opener by itself; a hand relying on it must explain how the graveyard reaches enough cards before activation matters.

- Automatic ship: Mulligan hands with no land and no Lion's Eye Diamond sequence that can legally start the engine. Also ship hands with mana but no Faithless Looting, Careful Study, Otherworldly Gaze, Breakthrough, dredger, or matchup-critical sideboard card.

- Automatic ship: Mulligan hands that contain only payoffs and battlefield material without setup. Narcomoeba, Bridge from Below, Poxwalkers, Dread Return, Thassa's Oracle, and Ox of Agonas are not an opening plan unless the hand also has a way to put cards into the graveyard and create legal follow-up decisions.

- Trap hand: Do not keep a hand because it contains Thassa's Oracle and Dread Return together. Those cards matter after the graveyard and sacrifice count are ready; an opener that cannot dredge or discard may strand both.

- Trap hand: Do not overvalue multiple Bridge from Below without a dredger and sacrifice outlet. Bridge from Below needs creatures dying from your side and graveyard placement; if the current hand cannot move cards or produce sacrifice fodder, it is a delayed payoff rather than a keep reason.

- Matchup-dependent keep: Keep Leyline of the Void only when it is in the opening hand and the opponent is on a graveyard plan or the matchup guidance says the card is decisive. Do not keep a weak no-engine hand solely for Leyline of the Void against an unknown or non-graveyard opponent unless the visible match context makes that disruption worth the lost speed.

- Matchup-dependent keep: Keep Unmask hands when the hand still has an engine after pitching a card, or when known disruption must be cleared before a fragile commitment. A hand that spends Unmask and then has no dredger, no enabler, and no pressure should usually mulligan.

- Play/draw rule: On the play, favor a faster Faithless Looting, Careful Study, Breakthrough, or Lion's Eye Diamond start over speculative protection. On the draw, accept slightly slower protected hands more often because the extra card may supply dredger, land, or Unmask fodder.

- Low-card rule: At six or five cards, prioritize one working engine over redundant payoffs. A five-card hand with land, Faithless Looting, Golgari Grave-Troll, and any reasonable follow-up is better than a seven-card hand full of Narcomoeba, Dread Return, Bridge from Below, and lands with no discard/draw action.

## Turn Arc

- Turn 1: Start the graveyard engine before developing decorative resources. Preferred plays are Faithless Looting discarding Golgari Grave-Troll or Stinkweed Imp, Careful Study discarding a dredger, Otherworldly Gaze setting up a dredger-heavy graveyard, or Breakthrough when the hand can accept going all-in.

- Turn 1: Use Lion's Eye Diamond only after the spell or activation line is committed and the discarded hand will be useful in the graveyard. The cleanest early use is enabling a burst draw/discard turn or a graveyard Faithless Looting line; avoid cracking it while required cards remain in hand without a committed legal action.

- Turn 1 deviation: Cast Cabal Therapy only when public information, revealed cards, or matchup context gives a meaningful name, or when sacrifice/Bridge from Below setup is already relevant. Blind Cabal Therapy is weaker than starting dredge unless the matchup is defined by a single disruptive card such as opponent: Force of Will or opponent: Surgical Extraction.

- Turn 2: Convert the first graveyard into multiple dredges and bodies. Replace draw events with Golgari Grave-Troll, Stinkweed Imp, or Golgari Thug when legal; use Narcomoeba, Bridge from Below, Poxwalkers, and Cabal Therapy flashback to create the sacrifice count for Dread Return.

- Turn 2: Preserve Cephalid Coliseum for a threshold burst if possible. Activate it when the graveyard is stocked enough that the draw three becomes dredge pressure and the discard three improves Dread Return, Ox of Agonas, Cabal Therapy, or Bridge from Below lines.

- Turn 2 deviation: If visible graveyard hate or open interaction threatens the engine, prioritize Unmask or Cabal Therapy before the Dread Return commitment. Do not expose Thassa's Oracle or the last Dread Return line into known disruption when a legal discard action can clear it first.

- Turn 3: Attempt the decisive conversion when sacrifice material, Dread Return, and a winning or reloading target are available. Dread Return for Thassa's Oracle is the primary deterministic payoff only when the library/graveyard state and legal resolution make it appropriate; Dread Return for Ox of Agonas is a reload line when more cards and dredges are needed.

- Turn 3: Use Cabal Therapy flashback as both disruption and engine glue. Sacrifice Narcomoeba or expendable token material when it clears a named problem, increases Bridge from Below output, or supplies the third creature for Dread Return.

- Turns 4-5: Shift from pure speed to resource conversion if the first wave was stopped. Use Ox of Agonas, Faithless Looting flashback, Cephalid Coliseum, and remaining dredgers to rebuild; keep tracking exiled Dread Return, Thassa's Oracle, Bridge from Below, and dredger counts before choosing a payoff line.

- Turns 4-5 deviation: Attack only when combat damage is the real path or when creatures are not needed as sacrifice material. Narcomoeba, Poxwalkers, and Bridge from Below tokens often matter more as Cabal Therapy or Dread Return resources than as attackers.

- Late game: Reassess the win condition from visible resources instead of assuming the opening combo still exists. If Thassa's Oracle or too many Dread Return copies are gone, lean on Ox of Agonas reloads, creature pressure, Bridge from Below token turns, and repeated dredge pressure.

- Late game: Stop dredging only when drawing a specific remaining live card is better than filling the graveyard. If the graveyard already contains enough engine pieces and the visible problem is a sideboard answer, land, or action currently in library, normal draws can become correct.

## Card Roles

- **Golgari Grave-Troll:** Treat Golgari Grave-Troll as the highest-volume dredge engine and the preferred first discard when a draw spell can convert immediately. Do not plan to cast it from hand in this registered mana base; its job is to turn Faithless Looting, Careful Study, Breakthrough, Cephalid Coliseum, and normal draw steps into graveyard velocity. Favor dredging it over smaller dredgers when the visible plan needs Narcomoeba triggers, Bridge from Below density, Dread Return access, or a fast Thassa's Oracle setup. Stop dredging it only when the current visible problem requires naturally drawing a specific remaining spell, land, or sideboard card.

- **Stinkweed Imp:** Use Stinkweed Imp as the second-best dredger and a stabilizing creature only when casting or blocking is actually legal and relevant. Its main role is still dredge volume; do not hold it in hand for combat if Faithless Looting, Careful Study, Breakthrough, or Cephalid Coliseum can put it into the graveyard. In slower games, a cast Stinkweed Imp can buy time against creature pressure, but the deck normally wins by making it a dredge replacement rather than by trading in combat.

- **Golgari Thug:** Use Golgari Thug as the smaller dredger that keeps engine density high and occasionally recycles a key creature. Its death trigger can matter if Thassa's Oracle, Narcomoeba, Ox of Agonas, or another creature must be returned to the top of the library, but do not create that line unless the rules engine presents a legal death/target choice and the top-card plan is better than continued dredging. Discard Golgari Thug freely when larger dredgers are absent; keep larger dredgers ahead of it when choosing replacement draws.

- **Faithless Looting:** Cast Faithless Looting early when it can discard Golgari Grave-Troll, Stinkweed Imp, Golgari Thug, Bridge from Below, Dread Return, Poxwalkers, or Ox of Agonas. Its flashback is a major rebuild tool after the first graveyard push, especially with Lion's Eye Diamond or excess red mana from Volcanic Island. Do not waste Faithless Looting as mere card selection when the hand already contains the needed dredger and an explosive Breakthrough or Cephalid Coliseum line; sequencing should maximize replacement draws, not hand sculpting for its own sake.

- **Careful Study:** Use Careful Study as the one-mana blue Faithless Looting analogue that starts the engine without requiring red mana. Because only one copy is registered, do not assume it is available in planning; when it appears, prioritize discarding dredgers and graveyard payoffs over holding speculative spells. Careful Study is weaker than a threshold Cephalid Coliseum burst but stronger than passing with dredgers stranded in hand.

- **Otherworldly Gaze:** Use Otherworldly Gaze to load the graveyard or set up the next draw before a dredge chain. It is strongest when it can place dredgers, Bridge from Below, Dread Return, Narcomoeba, Poxwalkers, or Ox of Agonas where they matter while preserving a draw event for dredge. Flashback makes it a resilient setup card after discard or milling. Do not treat Otherworldly Gaze as a full engine by itself if the next visible draw cannot become dredge or the graveyard lacks a payoff path.

- **Breakthrough:** Treat Breakthrough as the most dangerous burst enabler and commit only when discarding the hand is acceptable or actively beneficial. It is best with at least one dredger already in the graveyard or with Lion's Eye Diamond enabling a graveyard-loaded turn. Do not cast Breakthrough into an empty graveyard just to cycle cards unless the hand is otherwise failing and the legal draw/discard outcome is still better than waiting. If X choices are presented, preserve cards only when the visible hand contains a critical card that cannot profitably be discarded.

- **Lion's Eye Diamond:** Use Lion's Eye Diamond as a commitment resource, not a casual mana rock. Activate it when a spell or ability is already on the stack, when Faithless Looting flashback or Breakthrough can immediately exploit the discard, or when discarding the hand turns stranded dredgers/payoffs into resources. Do not crack Lion's Eye Diamond before selecting the legal action it pays for if losing the hand removes the only plan. Against known interaction, pair Lion's Eye Diamond turns with Cabal Therapy or Unmask when legal and not too slow.

- **Cephalid Coliseum:** Preserve Cephalid Coliseum for threshold when possible because draw three plus discard three can become a decisive dredge burst. It also fixes blue mana for Careful Study and Otherworldly Gaze, but repeated damage and timing matter. Activate only when threshold is present and the graveyard contains dredgers or the draw/discard mode materially improves the engine. Do not spend the land drop on a fetchable dual automatically if Cephalid Coliseum is needed to unlock the next turn.

- **Cabal Therapy:** Use Cabal Therapy as both disruption and a sacrifice outlet. Cast it from hand when public information, revealed cards, matchup context, or a narrow known threat gives a real name; blind naming is acceptable only when the matchup revolves around a small set of decisive answers such as opponent: Force of Will, opponent: Surgical Extraction, or opponent: Leyline of the Void. Flashback is often more important: sacrificing Narcomoeba, Bridge from Below tokens, or expendable Poxwalkers can clear interaction, trigger Bridge from Below, and build toward Dread Return.

- **Bridge from Below:** Treat Bridge from Below as a graveyard-only payoff that turns your sacrifice actions into bodies while it remains in the graveyard. It is poor in hand unless a discard spell can place it into the graveyard quickly. Protect it from exile indirectly by respecting opponent creatures dying; if the opponent can put a creature into its graveyard, Bridge from Below may disappear before it pays off. Sacrifice your own creatures through Cabal Therapy or Dread Return when legal and useful, but do not attack or trade away material if those bodies are needed for the combo turn.

- **Narcomoeba:** Use Narcomoeba as free battlefield material from dredge and self-mill, not as a creature to preserve for damage by default. Its main jobs are enabling Cabal Therapy flashback, supplying Dread Return creatures, and turning Bridge from Below sequences into more bodies. Attacking is correct only when the visible game has shifted to damage or when the creature is not needed for a near-term sacrifice plan. Do not keep opening hands because Narcomoeba is present; it belongs in the library or graveyard flow, not stranded in hand.

- **Poxwalkers:** Use Poxwalkers as recurring sacrifice material when spells are cast from zones other than hand. Card text check required for exact return condition and tapped status; treat every Poxwalkers recursion decision as conditional on the rules engine's legal action and visible trigger output. It pairs naturally with Faithless Looting flashback, Dread Return, and other graveyard-cast lines if the engine confirms the trigger. Do not rely on Poxwalkers as a blocker or normal threat; its value is repeated material for Cabal Therapy, Dread Return, and pressure after disruption.

- **Dread Return:** Treat Dread Return as the conversion spell that turns battlefield material into a decisive graveyard payoff. Flashback is the important mode; count three sacrificeable creatures before committing, and verify the intended target is legal. Use Cabal Therapy first when legal and needed to remove known disruption. Do not fire Dread Return for a medium target if waiting one more legal decision frame can produce Thassa's Oracle, a better Ox of Agonas reload, or enough Bridge from Below bodies to survive a failed attempt.

- **Thassa's Oracle:** Use Thassa's Oracle as the primary deterministic Dread Return payoff when the visible library/graveyard state makes the trigger lethal or strategically decisive. Do not cast or reanimate it merely because it is available; verify devotion, library size, trigger legality, and stack risk through engine output. If Thassa's Oracle is in hand, prioritize discard routes that make it a Dread Return target unless casting it is legal and actually wins or stabilizes.

- **Ox of Agonas:** Use Ox of Agonas as the reload payoff when the first dredge wave needs more cards rather than an immediate Thassa's Oracle finish. Its escape line can create draw events, discard stuck cards, and restart dredging if the graveyard has enough fuel and red mana is available. Dread Return for Ox of Agonas is a valid bridge line when Thassa's Oracle is unavailable or not yet lethal. Do not escape away essential graveyard resources without checking remaining Dread Return, Bridge from Below, dredger, and sacrifice-material counts.

- **Fetchlands and dual lands:** Use Flooded Strand, Polluted Delta, Misty Rainforest, and Scalding Tarn to access the correct early color while preserving Cephalid Coliseum timing. Volcanic Island supports Faithless Looting, Breakthrough, Otherworldly Gaze, and Careful Study patterns; Underground Sea supports Cabal Therapy and blue setup; Island is the stable blue source when damage, denial, or search constraints matter. Fetch decisions should follow the next legal spell, not abstract color balance.

## Interaction Priorities

- **Disrupt the card that stops the current engine turn first:** Use Cabal Therapy or Unmask on a known or highly likely graveyard hate, stack interaction, or exile effect before committing Lion's Eye Diamond, Breakthrough, Cephalid Coliseum, or Dread Return. Prioritize opponent: Leyline of the Void only before it resolves or when a legal discard action can take it from hand; once it is on the battlefield, shift to Into the Flood Maw or a sideboarded answer plan.

- **Name with information before guessing:** Fire Cabal Therapy from hand when the opponent's revealed hand, prior decisions, matchup, or public search effect identifies the card that matters. Blind Cabal Therapy should focus on one decisive blocker of the line, not general value. After dredging Narcomoeba or making Bridge from Below bodies, flashback Cabal Therapy to clear the last known disruption before Dread Return.

- **Protect Dread Return turns over setup turns:** If the visible graveyard already contains Dread Return, Thassa's Oracle or Ox of Agonas, dredgers, and enough sacrifice material, spend Cabal Therapy or Unmask on interaction that can stop the payoff. If the engine is not assembled, aim discard at graveyard hate or fast combo instead of speculative counterplay.

- **Bait with replaceable setup before decisive commitment:** Cast Otherworldly Gaze, Careful Study, or Faithless Looting first when they improve the graveyard and can draw interaction without costing the whole hand. Do not use Lion's Eye Diamond as bait unless the hand is already supposed to move to the graveyard or the legal line immediately spends the mana.

- **Bounce battlefield hate before rebuilding:** Use Into the Flood Maw first on hate permanents that currently disable graveyard actions, stop casting from the graveyard, or prevent the payoff from resolving. If multiple bounce targets are legal, choose the one that reopens the current turn's engine line over a generic blocker or clock piece.

- **Exile opposing graveyards when the matchup requires it:** Use Leyline of the Void as a pregame or early-game plan against graveyard mirrors and graveyard combo. Do not dilute the main engine for Leyline of the Void against fair decks unless their graveyard is a central route to beating Dread Return or Bridge from Below.

- **Use Siege Smash as answer coverage, not a tempo spell:** Card text check required. When sideboarded, spend Siege Smash on the permanent type it legally answers only if that permanent blocks the engine, invalidates the payoff, or creates a faster kill than the graveyard can beat.

- **Ignore low-impact creatures during combo setup:** Do not aim discard or bounce at ordinary attackers if life total and visible clock allow one more dredge turn. Shift to survival only when combat damage threatens lethal before the next engine action, when Bridge from Below would be exiled by an opposing creature dying, or when a blocker prevents a necessary attack-based finish.

- **Change interaction by archetype:** Against blue tempo or control, clear stack interaction before Breakthrough, Cephalid Coliseum, and Dread Return. Against fast combo, use Cabal Therapy and Unmask proactively even if the dredge engine slows down. Against permanent hate decks, prioritize Into the Flood Maw and Siege Smash lines. Against creature aggro, interact only with hate or lethal pressure; the graveyard engine remains the main stabilizer.

## Combat And Trading Rules

- **Preserve creatures as combo material first:** Treat Narcomoeba, Poxwalkers, and Bridge from Below tokens as resources for Cabal Therapy flashback and Dread Return before treating them as attackers. Do not attack with the third sacrifice creature if Dread Return is live or one dredge action can make the target lethal.

- **Attack when damage is the actual plan:** Send Narcomoeba, Poxwalkers, Bridge from Below tokens, Stinkweed Imp, Golgari Thug, or Golgari Grave-Troll only when the visible board shows that combat damage closes the game faster than waiting for Thassa's Oracle or Ox of Agonas. A stalled opponent with no graveyard hate can often be beaten by token pressure, but a nearly assembled Dread Return line should not be weakened for small attacks.

- **Block to buy the decisive draw step:** Block when the next incoming attack is lethal, when life total is low enough that Cephalid Coliseum damage or fetchland damage matters, or when one more turn likely enables Breakthrough, Cephalid Coliseum, Faithless Looting, Ox of Agonas, or Dread Return. Prefer blocking with creatures not needed for an immediate three-creature flashback cost.

- **Avoid trades that exile Bridge from Below:** Do not set up combat where an opposing creature dies if Bridge from Below is in the graveyard and the Bridge tokens or future sacrifice chain matter. Letting damage through is often correct when trading would remove Bridge from Below and collapse the Dread Return count.

- **Use Stinkweed Imp defensively when legally cast:** Stinkweed Imp can be a real deterrent if the game has slowed and the engine needs time. Card text check required for exact combat outcome, but do not trade it away casually if dredging it again is more important than killing one attacker.

- **Protect Poxwalkers recursion value:** Card text check required for exact return condition. If Poxwalkers can recur from visible legal actions, it can attack or block more freely than Narcomoeba, but do not rely on it unless the engine confirms the trigger and battlefield state.

- **Respect life thresholds without becoming a fair deck:** At 10 or more life, prefer engine advancement unless the opponent presents lethal next turn. At 6 to 9 life, count visible attackers and haste-like public threats before paying life, fetching, or taking Cephalid Coliseum damage. At 5 or less life, survival blocks and immediate Dread Return conversion outrank slow dredge setup.

- **Adjust combat by archetype:** Against creature aggro, block enough to preserve a full turn cycle and use tokens as a wall only after counting sacrifice needs. Against control, pressure with spare creatures after discard has cleared interaction, but hold enough bodies for Dread Return. Against combo, combat is secondary unless it creates a two-turn clock while Cabal Therapy or Unmask disrupts them. Against graveyard mirrors, Leyline of the Void changes combat into a normal pressure plan more often, but still preserve Dread Return material when available.

## Selection And Tutor Rules

- **Treat the deck as a pseudo-tutor engine:** There are no true library tutors in the registered main deck, so selection means choosing which draw events become dredges, which cards enter the graveyard, and which payoff is returned by Dread Return. Do not search for a named card unless the rules engine presents a legal search or target action.

- **Convert draw effects into dredge once a dredger is available:** Replace draws with Golgari Grave-Troll first when the graveyard needs maximum volume, then Stinkweed Imp, then Golgari Thug. Use the smaller dredger only when the larger dredger is unavailable, when decking risk is real, or when the legal prompt forces a specific replacement.

- **Use Faithless Looting as the safest selection bridge:** Cast Faithless Looting when the hand has a dredger to discard, Lion's Eye Diamond to convert the draw into a large graveyard turn, or a need to find a missing dredger without committing Breakthrough. On resolution, discard dredgers, Bridge from Below, Dread Return, Ox of Agonas, Poxwalkers, and excess lands before discarding live draw spells or payoff targets that still need timing.

- **Use Careful Study as a compact setup spell:** Cast Careful Study when blue mana is available and the hand needs to put a dredger into the graveyard without spending Lion's Eye Diamond. If both Careful Study and Faithless Looting are legal, prefer the spell that uses otherwise awkward mana and preserves the better follow-up flashback line.

- **Use Breakthrough as a commitment draw spell:** Cast Breakthrough when discarding most of the hand is acceptable or actively desired. With X equal to zero, assume the hand will be gone after the draw event; do this only when dredgers, Narcomoeba, Bridge from Below, Cabal Therapy, Dread Return, or Ox of Agonas can make the graveyard immediately productive.

- **Use Cephalid Coliseum threshold as a premium engine action:** Activate Cephalid Coliseum after threshold is present and the life payment is acceptable, especially when multiple dredgers can replace the draws. Delay the land drop if the choice is between playing a fetchland and holding Cephalid Coliseum for a same-turn threshold line, but make the land drop when mana is needed to cast Faithless Looting, Careful Study, Breakthrough, or Otherworldly Gaze.

- **Use Otherworldly Gaze to sculpt both graveyard and next draw:** At instant speed, put dredgers, Bridge from Below, Dread Return, Narcomoeba, Ox of Agonas, and recursive material into the graveyard when they advance the engine. Keep Lion's Eye Diamond, Cephalid Coliseum, a needed colored land, or a missing draw spell on top only when the next draw is not already being replaced by dredge.

- **Target Dread Return by game-ending role:** Choose Thassa's Oracle when the visible library is low enough or the engine confirms the Oracle line is lethal. Choose Ox of Agonas when the hand/graveyard state needs a fresh draw-discard burst and escape or cast lines are legal. Choose Golgari Grave-Troll only when combat size is the clear visible payoff and Thassa's Oracle or Ox of Agonas is not the right target.

- **Sequence fetchlands for color and threshold, not thinning:** Use Flooded Strand, Misty Rainforest, Polluted Delta, and Scalding Tarn to produce the color required by the current legal spell and to add graveyard count for threshold. Avoid unnecessary fetching when life total is under pressure or when the battlefield already supports the current turn.

## Priority And Stack Rules

- **Respect engine prompts before strategic preference:** Submit only legal actions exposed by Veles, and let rules-engine output define whether dredge replacement, Narcomoeba movement, Bridge from Below triggers, Poxwalkers recursion, flashback, escape, or Dread Return targeting is currently legal.

- **Hold priority only for real instant-speed value:** Cast Otherworldly Gaze on the opponent's end step when it can set up the next draw step, protect information until the last moment, or put dredgers into the graveyard before a planned Faithless Looting, Breakthrough, or Cephalid Coliseum turn. Do not spend it into open pressure if the top-card choice is irrelevant and the card is better as flashback fuel later.

- **Crack Lion's Eye Diamond at commitment windows:** Activate Lion's Eye Diamond only when the legal line can immediately use the mana through Faithless Looting flashback, Breakthrough resolution planning, Cephalid Coliseum activation, Ox of Agonas escape, or another visible engine action. Do not discard a functional hand just because Lion's Eye Diamond is legal.

- **Let opponent spells resolve when they do not change the engine:** Pass priority on creatures, cantrips, and nonlethal pressure unless the spell represents graveyard hate, stack interaction for the current payoff, or a faster kill than the dredge turn can beat. This deck has limited stack interaction, so priority decisions usually mean whether to advance Otherworldly Gaze, Lion's Eye Diamond, Cabal Therapy flashback, or sideboard answers.

- **Use Cabal Therapy before the decisive stack point:** Cast or flash back Cabal Therapy before committing Breakthrough, Cephalid Coliseum threshold activation, or Dread Return when public information identifies a disruptive card. If the opponent's hand is unknown, blind-name only when the matchup and visible context make one card clearly more dangerous than waiting.

- **Resolve Narcomoeba and Bridge from Below value carefully:** Accept Narcomoeba battlefield placement when it supplies Cabal Therapy or Dread Return material. Preserve Bridge from Below by avoiding stack or combat choices that cause opposing creatures to die before Bridge tokens matter.

- **Treat Dread Return flashback as the critical stack event:** Before sacrificing three creatures, confirm the target, sacrifice material, opponent disruption risk, and Bridge from Below implications from visible state. Once the payoff target is chosen, use any available Cabal Therapy or Unmask first if the rules engine still offers a legal pre-commitment window.

- **Use Ox of Agonas only when the draw-discard trigger improves the position:** Card text check required for exact escape and trigger details. If Ox of Agonas is legal, prefer it when it reloads dredges, finds another draw engine, or creates enough graveyard movement to reach Dread Return; avoid it when drawing three risks decking without a payoff.

- **Use sideboard instant windows defensively:** Cast Into the Flood Maw only when bouncing the visible permanent reopens the graveyard, protects the payoff turn, or prevents lethal. Cast Siege Smash only when its verified text legally answers the permanent or stack problem that blocks the engine; card text check required.

## Sideboard Map

- **Sideboard posture:** Sideboarding must preserve the graveyard-combo core while adding only the role cards that solve a visible opposing pressure point. LED Dredge wins by converting discard outlets, dredgers, Narcomoeba, Bridge from Below, Cabal Therapy, Dread Return, Ox of Agonas, and Thassa's Oracle into a fast kill; do not dilute that core unless the opposing deck presents graveyard hate, faster combo, lock pieces, or a graveyard mirror that changes the axis.

- **Unmask role:** Bring in Unmask against combo, fast prison, graveyard hate decks, and blue interaction decks where taking one card before the engine turn is worth a card. Use it to clear opponent disruption before Breakthrough, Cephalid Coliseum, or Dread Return, and to attack a faster combo before it acts. Unmask is worse against low-interaction creature decks when the extra card cost slows the dredge engine more than the discard helps.

- **Into the Flood Maw role:** Bring in Into the Flood Maw when the opponent can present a permanent that blocks the graveyard plan, battlefield access, or the payoff turn. Card text check required; use only according to legal action text shown by Veles. If the visible legal action returns a hate permanent or lethal attacker to hand, it can reopen the combo turn or buy a turn. It is worse when the opponent has no relevant permanent, when bounce does not answer the actual lock, or when spending blue mana prevents Faithless Looting flashback, Careful Study, Otherworldly Gaze, Breakthrough, or Cephalid Coliseum from driving the engine.

- **Siege Smash role:** Bring in Siege Smash against artifact, enchantment, or permanent-hate configurations only if the verified card text and legal Veles actions show it answers the relevant permanent type. Card text check required. Treat Siege Smash as a sideboard answer, not a proactive engine card; it is bad when no target is visible, when the opponent's hate is stack-based or hand-based, or when the mana/action cost slows a hand that can already race.

- **Leyline of the Void role:** Bring in Leyline of the Void against graveyard mirrors, recursive combo, reanimator-style opponents, and decks where the opponent's graveyard is their primary resource. Keep it only when it is in the opening hand or when hard-casting is realistically supported by visible lands and game pace. It is bad against fair decks without graveyard dependency because it does not dredge, discard, draw, flashback, sacrifice, or return with Dread Return.

- **Role-change rule:** Against heavy hate, become a protected combo deck instead of a pure speed deck. Add role cards that answer or preempt hate, then reduce the most fragile speed pieces that require discarding the whole hand or expose the engine to a single answered payoff.

- **Role-change rule:** Against faster combo, become a discard-backed combo deck. Add role cards that interact before the opponent's decisive turn, then reduce slower graveyard payoffs and redundant recursive bodies that matter only after the engine is already moving.

- **Role-change rule:** Against fair creature pressure with little hate, stay mostly proactive. Add only the sideboard cards that answer a visible lock piece or lethal battlefield, and keep the highest density of dredgers, draw-discard spells, Lion's Eye Diamond, Cabal Therapy, Bridge from Below, Narcomoeba, and Dread Return.

Blue Graveyard-Hate Or Control Permanent Plan
Role cards: 4 Unmask; 4 Into the Flood Maw
Trim roles: 1 Careful Study; 2 Breakthrough; 1 Poxwalkers; 1 Golgari Thug; 1 Bridge from Below; 1 Ox of Agonas; 1 Dread Return

- **Plan logic:** Use this plan when the opponent combines permission, discard, or permanent hate with enough time to interact. Unmask protects the decisive engine turn; Into the Flood Maw handles a visible permanent that otherwise invalidates the graveyard or Dread Return line. The reductions preserve all four Golgari Grave-Troll, all four Stinkweed Imp, all four Faithless Looting, all four Otherworldly Gaze, all four Lion's Eye Diamond, all four Narcomoeba, and enough Dread Return structure to still kill.

Fast Combo Or Stack-Light Race Plan
Role cards: 4 Unmask
Trim roles: 1 Careful Study; 1 Poxwalkers; 1 Bridge from Below; 1 Golgari Thug

- **Plan logic:** Use this plan when the matchup is decided by whether the opponent executes first and Unmask can remove the key card or confirm safety. Keep Breakthrough and Lion's Eye Diamond because speed matters. Avoid overloading on non-engine cards when the opponent is not presenting permanents that Into the Flood Maw or Siege Smash can answer.

Graveyard Mirror Or Opposing Graveyard Engine Plan
Role cards: 4 Leyline of the Void; 4 Unmask
Trim roles: 1 Careful Study; 2 Breakthrough; 1 Poxwalkers; 1 Bridge from Below; 1 Golgari Thug; 1 Ox of Agonas; 1 Dread Return

- **Plan logic:** Use this plan when Leyline of the Void can invalidate the opponent's primary resource and Unmask can protect Leyline or slow their answer. Mulligan priorities change sharply: an opening Leyline of the Void plus any functional dredge setup can be better than a faster hand that loses to the opposing graveyard engine. Do not keep Leyline-only hands that cannot cast spells, discard dredgers, or find a draw engine.

Artifact Or Enchantment Hate Plan
Role cards: 3 Siege Smash; 4 Into the Flood Maw
Trim roles: 1 Careful Study; 2 Breakthrough; 1 Poxwalkers; 1 Golgari Thug; 1 Bridge from Below; 1 Ox of Agonas

- **Plan logic:** Use this plan only when the opponent is expected to present permanents that the verified text of Siege Smash or the legal action text for Into the Flood Maw can answer. This is a slower configuration, so keep hands that can either answer the hate and immediately restart or ignore the hate because the opponent did not deploy it. Do not bring this plan against vague interaction without a permanent target.

- **Archetype rule, creature decks:** Add role cards only for graveyard hate or lethal-board prevention. Reduce main-deck emphasis on the slowest redundant payoff pieces rather than dredger count. Keep Cabal Therapy because sacrificing Narcomoeba or token material can clear removal, protect Dread Return, or disrupt a combat trick when public information supports a name.

- **Archetype rule, prison decks:** Add role cards that interact with lock permanents and hand disruption before the lock resolves. Reduce main-deck emphasis on all-in discard-draw lines when the opponent can punish a discarded hand with a single unresolved hate piece. Lion's Eye Diamond remains powerful only when a visible follow-up exists.

- **Archetype rule, graveyard hate decks:** Add role cards according to the actual hate type shown or strongly represented by public information. Into the Flood Maw is for bounceable permanents if legal; Siege Smash is for verified permanent classes if legal; Unmask is for taking hate before it lands. Avoid adding Leyline of the Void unless the opponent's own graveyard is also central.

- **Archetype rule, graveyard mirrors:** Add Leyline of the Void aggressively and value opening-hand presence higher than normal engine smoothness. Unmask can remove an answer, a draw-discard engine, or a payoff from the opponent. Reduce main-deck emphasis on slower recursive bodies because Leyline games often hinge on whether either graveyard engine functions at all.

- **Post-sideboard mulligan rule:** Keep hands that combine a sideboard role card with a real engine path. A hand with Leyline of the Void, Unmask, or an answer spell still needs a dredger, discard outlet, draw engine, or a realistic route to one; sideboard cards do not win alone unless the opponent is already locked and the engine can develop afterward.

Explicit Sideboard Repair Plans

These balanced plans are legal Veles candidates built from the registered sideboard and main deck. Use them as baseline sideboarding options only when the matchup role fits; keep the role guidance above as the strategic source of truth.

Cut: 2 Lion's Eye Diamond; 2 Poxwalkers

Legal repair plan 4
Side in: Unmask; 3 Into the Flood Maw
Cut: Lion's Eye Diamond; 3 Poxwalkers

## Matchup Guidance

- **Aggro:** Race creature decks by prioritizing a functional dredge start over reactive hands. Keep hands with Golgari Grave-Troll, Stinkweed Imp, or Golgari Thug plus Faithless Looting, Otherworldly Gaze, Careful Study, Breakthrough, Cephalid Coliseum, or Lion's Eye Diamond; do not keep a slow sideboard hand that only answers one creature. Bridge from Below and Narcomoeba matter because they convert dredging into blockers, Cabal Therapy sacrifices, and Dread Return material. Add role cards: Into the Flood Maw only when a legal visible action answers a decisive creature or hate permanent; Siege Smash only if verified card text and legal action text show it answers the relevant permanent. Card text check required. Reduce main-deck emphasis: slow redundant payoffs such as extra Poxwalkers or one Ox of Agonas before reducing dredger density.

- **Control:** Beat control by forcing them to answer the graveyard engine on multiple axes instead of walking one all-in spell into open interaction. Value Cabal Therapy as both disruption and sacrifice outlet; use revealed information before naming, and prefer Unmask when the matchup is about resolving the first decisive discard-draw turn through permission or graveyard hate. Lion's Eye Diamond plus Faithless Looting or Breakthrough is powerful, but only commit when the visible legal follow-up actually dredges or flashes back a payoff. Add role cards: Unmask; Into the Flood Maw for visible permanent hate if legal. Reduce main-deck emphasis: the most fragile all-in Breakthrough lines and slower recursive bodies when the opponent can punish a discarded hand.

- **Combo:** Against faster combo, become a discard-backed graveyard combo deck. Keep speed hands when they can produce a turn-one or turn-two dredge explosion, but value Unmask and Cabal Therapy highly when public information says the opponent may win first. Use Cabal Therapy flashback with Narcomoeba, Bridge from Below tokens, or expendable Poxwalkers only when the named card is based on revealed information, known archetype pressure, or a narrow must-stop role. Add role cards: Unmask. Reduce main-deck emphasis: slow graveyard value cards that do not accelerate Dread Return, Thassa's Oracle, Ox of Agonas, or a lethal board.

- **Tempo:** Play through tempo by sequencing low-cost enablers before large commitment spells when possible. Otherworldly Gaze is valuable because it can stock the graveyard without requiring a full-hand discard, while Faithless Looting and Careful Study let the deck keep functioning under pressure. Do not spend Lion's Eye Diamond just because it is legal; spend it when the visible action chain includes Faithless Looting flashback, Breakthrough resolution, Cephalid Coliseum threshold activation, or another concrete engine payoff. Add role cards: Unmask when the opponent is likely to protect a fast clock with permission or hate; Into the Flood Maw when a visible creature or hate permanent is the bottleneck and the rules engine offers a legal action.

- **Midrange:** Grind midrange by making their one-for-one removal and discard poor against dredgers, recursive creatures, Bridge from Below, and flashback. A hand with a dredger plus repeatable draw or graveyard access is usually stronger than a hand with only one explosive spell and no backup. Cabal Therapy should protect Dread Return, clear hate, or disrupt the opponent's stabilizing card; do not sacrifice material blindly if Bridge from Below tokens are needed for a later return. Add role cards: Unmask for hate-heavy builds; Siege Smash or Into the Flood Maw only for verified visible permanents. Reduce main-deck emphasis: one Breakthrough or slow payoff density before touching Golgari Grave-Troll or Stinkweed Imp.

- **Big mana:** Pressure big mana before their high-impact turns by maximizing early dredge volume and Dread Return access. Keep Lion's Eye Diamond hands that have a real engine payoff, because waiting gives the opponent time to deploy sweepers, lock permanents, or graveyard interaction. Cabal Therapy is best when it strips the card that buys them the decisive extra turn or removes a visible/revealed hate piece. Add role cards: Unmask against builds with stack interaction, sweepers, or graveyard hate; Into the Flood Maw or Siege Smash only when their permanent interaction is visible or strongly expected and legal text supports the answer.

- **Graveyard decks:** Mulligan and sideboard as a mirror-resource fight. Leyline of the Void is high-impact only when it starts in the opening hand or when hard-casting is realistic from visible lands and game pace; do not keep a Leyline of the Void hand that cannot also begin a dredge plan. Unmask can protect Leyline of the Void, remove an opposing enabler, or clear an answer. Add role cards: Leyline of the Void; Unmask. Reduce main-deck emphasis: slower Poxwalkers, one Bridge from Below, one Golgari Thug, or extra payoff copies before reducing primary dredgers.

- **Artifact/enchantment decks:** Treat permanent hate as the central question only when the opponent actually presents or strongly telegraphs it. Into the Flood Maw and Siege Smash are not engine cards; use them when legal action text identifies a relevant permanent target and the tempo loss is smaller than losing access to the graveyard. Card text check required for Siege Smash and any uncertain target class. Add role cards: Into the Flood Maw; Siege Smash. Reduce main-deck emphasis: Breakthrough and slower payoff density when the matchup punishes all-in graveyard commitment with one permanent.

- **Go-wide decks:** Use the graveyard engine to go wider faster rather than trading fair creatures too early. Bridge from Below, Narcomoeba, Poxwalkers, Cabal Therapy flashback, and Dread Return can convert dredges into a larger battlefield than normal creature decks can manage. Preserve sacrifice bodies when they are needed for Dread Return or Cabal Therapy; block only when survival, Bridge from Below timing, or a decisive counterattack requires it. Add role cards: Into the Flood Maw only for a visible creature or hate piece that changes the race; avoid sideboard cards that reduce dredge density without answering the actual board.

- **Single-threat decks:** Answer the bottleneck threat or ignore it with a faster combo finish. If the single threat is the clock and no hate is present, prioritize dredging, Bridge from Below tokens, Narcomoeba, and Dread Return over reactive play. If the threat carries or protects graveyard hate, route through Unmask, Cabal Therapy, Into the Flood Maw, or Siege Smash according to visible legal actions. Add role cards: Into the Flood Maw for a legal visible threat answer; Unmask when the threat is backed by stack or hand interaction. Reduce main-deck emphasis: slow recursive bodies, not core enablers.

- **Burn:** Race burn by minimizing self-inflicted delays and maximizing fast dredge volume. Keep hands that immediately put Golgari Grave-Troll, Stinkweed Imp, or Golgari Thug into motion; avoid hands that spend several turns casting sideboard cards without building a graveyard. Cabal Therapy can matter if public information or a reveal narrows the card to name, but do not overvalue discard at the cost of a faster Dread Return or Ox of Agonas line. Add role cards: Unmask only when it clearly buys a turn or protects a kill; avoid Leyline of the Void unless the opponent's graveyard is central.

- **Removal-heavy decks:** Make removal awkward by forcing it to interact with Narcomoeba, Bridge from Below tokens, recursive Poxwalkers, and graveyard payoffs instead of one creature. Do not expose Thassa's Oracle or a key Dread Return line until the visible graveyard, battlefield sacrifice count, and opponent interaction risk justify commitment. Cabal Therapy is a protection spell here; flash it back before Dread Return when a legal sacrifice body is available and a specific removal or hate card is known, revealed, or strongly implied. Add role cards: Unmask against high-density interaction; Into the Flood Maw or Siege Smash for visible permanents that stop the engine.

## Specific Matchup Notes

- **General note:** Treat these matchup notes as archetype-only until the opponent reveals cards; revealed cards, public zones, legal action text, and Veles state always override assumptions. Do not name a card with Cabal Therapy from memory alone unless a reveal, prior action, deck identity, or public pattern makes the name tactically justified.

- **Fast combo:** Race by opening on the highest dredge-volume line that also supports disruption. Prioritize Lion's Eye Diamond with Faithless Looting, Breakthrough, or Cephalid Coliseum when the hand can move Golgari Grave-Troll, Stinkweed Imp, or Golgari Thug into the graveyard immediately. Add role cards: Unmask. Reduce main-deck emphasis: slower recursive pressure such as Poxwalkers, one Bridge from Below, or excess payoff density. Priority targets are the opponent's visible enabler, protection spell, or payoff that wins before Dread Return can resolve.

- **Blue permission:** Lead with cheap enablers and use Cabal Therapy or Unmask before committing Dread Return, Breakthrough, or a Lion's Eye Diamond line that empties the hand. Otherworldly Gaze is strong when the opponent can punish all-in discard because it advances the graveyard without requiring full commitment. Add role cards: Unmask. Reduce main-deck emphasis: one slower payoff or one lower-impact recursive card before reducing Golgari Grave-Troll or Stinkweed Imp. Priority targets are the counterspell or graveyard hate action most likely to stop the selected turn.

- **Graveyard hate permanents:** Identify whether the bottleneck is already visible, merely suspected, or only possible. Into the Flood Maw is for a legal visible target that must leave the battlefield before the engine works; Siege Smash needs card text check required and should be used only when its legal target text answers the actual permanent. Add role cards: Into the Flood Maw; Siege Smash. Reduce main-deck emphasis: slower payoffs, not core dredgers. Priority targets are the hate permanent first, then protection for that permanent.

- **Creature pressure:** Ignore normal combat when a faster graveyard finish is available, but block when survival or Bridge from Below timing makes the block materially better than preserving bodies. Narcomoeba and Poxwalkers are resources for Cabal Therapy and Dread Return before they are fair attackers. Add role cards: Into the Flood Maw only for a visible creature or hate permanent that changes the race. Reduce main-deck emphasis: reactive cards that do not accelerate dredging unless the visible board demands time.

- **Attrition midrange:** Use the graveyard as the card-advantage engine and make one-for-one removal poor. Cabal Therapy flashback is high value when it both disrupts and converts Bridge from Below into bodies. Ox of Agonas can rebuild after discard or stalled dredges when legal action text supports escape or casting; Card text check required if the exact graveyard-exile cost matters at runtime. Add role cards: Unmask for hate or stack interaction; Into the Flood Maw or Siege Smash only for confirmed permanents. Reduce main-deck emphasis: one Breakthrough or slower recursive pressure before primary dredgers.

- **Mirror or graveyard decks:** Leyline of the Void matters most from the opening hand, so do not keep a hand that has Leyline of the Void but no path to start dredging. Unmask can protect Leyline of the Void or attack the opposing enabler. Add role cards: Leyline of the Void; Unmask. Reduce main-deck emphasis: Poxwalkers, one Bridge from Below, one Golgari Thug, or excess payoff density. Priority targets are opposing graveyard enablers, answers to Leyline of the Void, and any payoff about to resolve.

## Risk Summary

- **Mana risk:** The deck has few lands and relies heavily on Lion's Eye Diamond, Faithless Looting, Breakthrough, Careful Study, Otherworldly Gaze, and Cephalid Coliseum to convert mana into graveyard velocity. Do not keep slow hands that need multiple natural land drops unless they already contain a dredger and a legal route to draw or discard.

- **Draw-risk:** Opening hands without Golgari Grave-Troll, Stinkweed Imp, Golgari Thug, or a way to find/discard one can fail to function despite looking spell-dense. Prioritize enabler-plus-dredger structures over hands that only contain Narcomoeba, Bridge from Below, Poxwalkers, Dread Return, Thassa's Oracle, or Ox of Agonas.

- **Over-sideboarding risk:** Adding too many Unmask, Into the Flood Maw, Siege Smash, or Leyline of the Void can reduce dredge density and make the deck play a weak fair game. Post-board hands still need a graveyard engine, not only answers.

- **Graveyard risk:** The deck loses much of its power when the graveyard is inaccessible, exiled, or delayed. Before committing Lion's Eye Diamond or Breakthrough, check whether the opponent has visible graveyard interaction, revealed hate, or mana and timing that make waiting with Otherworldly Gaze, Cabal Therapy, or Unmask safer.

- **Sweeper/removal risk:** Bridge from Below and sacrifice bodies are fragile resources. Do not spend Narcomoeba or Poxwalkers on low-impact Cabal Therapy flashback when those bodies are needed for Dread Return, and remember that opposing creature deaths can matter for Bridge from Below timing if the rules engine exposes that result.

- **Closer risk:** Dread Return lines require enough sacrifice material and a payoff that actually wins or stabilizes. Thassa's Oracle is powerful only when the visible library/graveyard state and legal action text support the finish; Ox of Agonas is stronger as rebuild or velocity when the immediate Oracle kill is not established.

- **Interaction risk:** Cabal Therapy and Unmask are strongest when aimed at known or highly constrained cards. Blind disruption that misses can cost the exact resources needed for the combo turn.

- **Sequencing risk:** Lion's Eye Diamond should be cracked only when the pending action uses the mana or discard immediately, such as Faithless Looting flashback, Breakthrough, Cephalid Coliseum threshold activation, or a selected Dread Return turn. Passing after discarding the hand without a concrete engine payoff is one of the deck's largest avoidable failures.

## Test Feedback Checklist

- Match deciding factor: Record whether the game was decided by speed, graveyard access, a visible hate permanent, stack interaction, creature pressure, or a failed closer. Tie the note to the exact turn and legal action where the plan changed.

- Mulligan quality: For every keep, ask whether the hand contained Golgari Grave-Troll, Stinkweed Imp, Golgari Thug, or a credible way to find and discard one. Flag keeps that had only Narcomoeba, Bridge from Below, Poxwalkers, Dread Return, Ox of Agonas, or Thassa's Oracle without an engine.

- Mana conversion: Check whether Lion's Eye Diamond, Cephalid Coliseum, Underground Sea, Volcanic Island, Island, and fetch lands produced the needed color and timing. Mark failures where Lion's Eye Diamond was cracked without an immediate Faithless Looting, Breakthrough, Cephalid Coliseum, Dread Return, or other legal payoff.

- Velocity: Ask whether Faithless Looting, Breakthrough, Careful Study, Otherworldly Gaze, and Cephalid Coliseum produced enough dredge volume before the opponent's clock or hate mattered. Separate slow hands from mis-sequenced hands.

- Engine execution: Track whether Narcomoeba, Poxwalkers, Bridge from Below, and Cabal Therapy generated enough bodies for Dread Return. Note any Cabal Therapy flashback that spent bodies needed for the closing line.

- Disruption value: For Cabal Therapy and Unmask, record whether the chosen name or exile decision was based on visible information, revealed information, matchup logic, or a blind guess. Flag misses that cost a critical combo resource.

- Closing attempt: For each Dread Return line, ask whether Thassa's Oracle, Ox of Agonas, or another target actually advanced the win from the visible library, graveyard, battlefield, and legal action text. Record failed closes separately from disrupted closes.

- Sideboard impact: Evaluate whether Unmask, Into the Flood Maw, Siege Smash, and Leyline of the Void changed the game they entered. Mark over-sideboarded games where answer density reduced dredger, enabler, or sacrifice-body density.

- Removal and hate answers: When Into the Flood Maw or Siege Smash was drawn, ask whether a legal visible target existed and whether using it before dredging was necessary. For Siege Smash, keep decisions conditional until card text check required is resolved.

- Stranded-card audit: List cards stranded in hand or graveyard because mana, threshold, sacrifice bodies, target legality, or timing was missing. Pay special attention to Breakthrough, Dread Return, Ox of Agonas, Thassa's Oracle, and sideboard answers.

- Role and mistake review: Ask whether the pilot correctly identified race, disrupt, rebuild, or answer-hate mode. Note any pass, attack, block, discard, or priority decision that contradicted the visible board state or engine needs.

## First Tuning Questions

- Dredger density: If opening hands often lack Golgari Grave-Troll, Stinkweed Imp, or Golgari Thug, should the list protect maximum dredger count instead of shaving Golgari Thug or relying on Otherworldly Gaze to find one?

- Enabler mix: If Breakthrough creates too many all-in losses into interaction, should the second Breakthrough remain, or should the deck lean more on Faithless Looting, Careful Study, Otherworldly Gaze, and Cephalid Coliseum for lower-commitment starts?

- Lion's Eye Diamond dependency: If wins cluster only around Lion's Eye Diamond, ask whether non-LED hands are being kept too often or whether the pilot guide needs stricter mulligan rules for hands without immediate discard-draw velocity.

- Mana base pressure: If Cephalid Coliseum or colored spells are stranded, review whether Underground Sea, Volcanic Island, Island, Polluted Delta, Flooded Strand, Misty Rainforest, and Scalding Tarn provide enough reliable blue and red access for the current sequencing rules.

- Poxwalkers role: If Poxwalkers mostly fails to return or attacks for low impact, consider whether three copies are correct, especially in post-board games where sacrifice bodies still matter but speed and answer density compete for slots.

- Bridge from Below count: If Bridge from Below is often win-more, stranded, or neutralized by opposing creature deaths, test whether three copies remain correct. If Dread Return frequently lacks bodies, do not reduce Bridge from Below before reviewing sacrifice sequencing.

- Dread Return package: If Dread Return is stranded without targets or bodies, ask whether three copies are too many. If Thassa's Oracle lines frequently win immediately, keep enough Dread Return density to find and execute the deterministic payoff.

- Ox of Agonas role: If Ox of Agonas rebuilds stalled games, preserve it as a secondary engine. If it is mostly uncastable or conflicts with graveyard resources, review whether two copies are necessary.

- Disruption slots: If Cabal Therapy and Unmask are missing too often or naming poorly, tune the decision guide before changing quantities. If known hate still resolves through disruption, test whether more post-board emphasis on Unmask is needed.

- Answer suite: If graveyard hate permanents decide post-board games, evaluate whether Into the Flood Maw and Siege Smash cover the right visible target types. Resolve Siege Smash card text check required before treating it as a reliable hate answer.

- Leyline plan: If Leyline of the Void wins mirrors but creates nonfunctional hands elsewhere, restrict it to graveyard matchups and avoid bringing it into fair matchups where dredge velocity matters more.

- Role conflict: If post-board games lose because the deck becomes half-combo and half-answer, reduce main-deck emphasis on slower payoffs before cutting core dredgers or enablers, and keep every plan centered on starting the graveyard engine quickly.

## Veles Tactical Policy

### Policy: Opening Engine Keep Gate
Priority: High
Decision families: mulligan
Cards: Golgari Grave-Troll; Stinkweed Imp; Golgari Thug; Faithless Looting; Careful Study; Otherworldly Gaze; Lion's Eye Diamond; Cephalid Coliseum; Breakthrough
Phase windows: opening hand, mulligan decisions
Runtime cues: prompt:mulligan; action:keep; action:mulligan
Use when: keep only hands with a dredger plus a legal discard/draw path, or a fast way to find and discard a dredger with mana.
Avoid when: the hand is only payoffs, free creatures, Bridge from Below, Dread Return, or sideboard cards without engine access.
Instructions: Value functional dredge starts over card quantity. Lion's Eye Diamond hands need an immediate legal payoff, not hope.
Pilot skill floor: medium
No-API allowed: no
Light-model allowed: yes

### Policy: Early Graveyard Setup
Priority: Medium
Decision families: priority, selection, mana
Cards: Faithless Looting; Careful Study; Otherworldly Gaze; Breakthrough; Lion's Eye Diamond; Golgari Grave-Troll; Stinkweed Imp; Golgari Thug
Phase windows: turns 1-2, main phases, first priority windows
Runtime cues: action:cast Faithless Looting; action:cast Careful Study; action:cast Otherworldly Gaze; action:cast Breakthrough
Use when: choose the legal enabler that puts a dredger into the graveyard while preserving the strongest follow-up draw or dredge.
Avoid when: casting a draw spell would draw normally with no dredger available and no visible setup benefit.
Instructions: Start dredging before protecting payoffs. Otherworldly Gaze can set up the graveyard but should not replace a direct discard-draw engine when one is legal.
Pilot skill floor: medium
No-API allowed: no
Light-model allowed: yes

### Policy: Lion's Eye Diamond Commitment Gate
Priority: High
Decision families: mana, priority
Cards: Lion's Eye Diamond; Faithless Looting; Breakthrough; Cephalid Coliseum; Dread Return; Ox of Agonas
Phase windows: main phases, priority before draw/discard payoffs, combo turn
Runtime cues: action:activate Lion's Eye Diamond
Use when: crack Lion's Eye Diamond only with a visible legal action or pending spell/ability that converts the discarded hand into dredges, mana, or a Dread Return turn.
Avoid when: no immediate payoff is legal or the hand contains needed interaction or sideboard answers that would be discarded without conversion.
Instructions: Treat Lion's Eye Diamond as a commitment gate, not routine mana. Reason about stack state, graveyard count, threshold, and whether waiting loses to visible pressure.
Pilot skill floor: high
No-API allowed: no
Light-model allowed: yes

### Policy: Cephalid Coliseum Threshold Conversion
Priority: High
Decision families: mana, priority, selection
Cards: Cephalid Coliseum; Golgari Grave-Troll; Stinkweed Imp; Golgari Thug; Lion's Eye Diamond
Phase windows: main phases after threshold, combo turn
Runtime cues: action:activate Cephalid Coliseum
Use when: threshold is visible and the activation can replace draws with dredges or discard newly found dredgers.
Avoid when: threshold is absent, blue mana is not available, or activating would force normal draws while a better engine action is legal.
Instructions: Use Cephalid Coliseum as a burst dredge engine. Count graveyard size and visible dredgers before choosing it over Faithless Looting or Breakthrough.
Pilot skill floor: high
No-API allowed: no
Light-model allowed: yes

### Policy: Dredge Replacement Selection
Priority: High
Decision families: selection
Cards: Golgari Grave-Troll; Stinkweed Imp; Golgari Thug
Phase windows: draw replacement prompts, resolving draw spells and abilities
Runtime cues: action:dredge Golgari Grave-Troll; action:dredge Stinkweed Imp; action:dredge Golgari Thug
Use when: replace draws with the largest visible dredge that advances the graveyard engine unless a smaller dredge preserves a known required card or library survival.
Avoid when: library size is too low for the dredge amount or a normal draw is required to access a specific visible answer.
Instructions: Golgari Grave-Troll is the default volume engine, Stinkweed Imp is the next volume engine, and Golgari Thug is acceptable when library size or card access demands it.

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

### Policy: Narcomoeba And Bridge Body Preservation
Priority: Medium
Decision families: combat, priority, interaction
Cards: Narcomoeba; Bridge from Below; Poxwalkers; Cabal Therapy; Dread Return
Phase windows: combat, sacrifice prompts, main phases before Dread Return
Runtime cues: action:attack; action:block; action:flashback Cabal Therapy; action:flashback Dread Return
Use when: preserve three sacrifice bodies for Dread Return unless a legal sacrifice or block prevents lethal, strips critical interaction, or creates a better immediate engine line.
Avoid when: attacking or blocking exposes needed bodies without changing the race or protecting the combo.
Instructions: Treat Narcomoeba and Poxwalkers primarily as combo material. Bridge from Below rewards sacrifice sequencing but is vulnerable to opposing creature deaths.
Pilot skill floor: medium
No-API allowed: no
Light-model allowed: yes

### Policy: Cabal Therapy Disruption Gate
Priority: Medium
Decision families: interaction, priority, selection
Cards: Cabal Therapy; Narcomoeba; Poxwalkers; Bridge from Below
Phase windows: main phases, before committing Lion's Eye Diamond or Dread Return
Runtime cues: action:cast Cabal Therapy; action:flashback Cabal Therapy; prompt:name a card
Use when: use Cabal Therapy to clear visible or strongly inferred disruption before an all-in line, or to sacrifice creatures when Bridge from Below and Dread Return math supports it.
Avoid when: flashback consumes the third Dread Return body or blind naming delays a faster legal win.
Instructions: Name from revealed information first. Without revealed information, reason from matchup, mana, and public plays; do not invent hidden cards.
Pilot skill floor: high
No-API allowed: no
Light-model allowed: yes

### Policy: Dread Return Commitment Gate
Priority: High
Decision families: priority, selection
Cards: Dread Return; Thassa's Oracle; Ox of Agonas; Golgari Grave-Troll; Narcomoeba; Poxwalkers; Bridge from Below
Phase windows: main phases with three sacrifice creatures
Runtime cues: action:flashback Dread Return; action:cast Dread Return
Use when: commit to Dread Return when the visible graveyard, battlefield, library count, and target options produce a win, a decisive reload, or a necessary stabilizing body.
Avoid when: target choice is unclear, sacrifice bodies are insufficient after costs, or known interaction makes waiting better and not lethal.
Instructions: Thassa's Oracle is the deterministic payoff only when legal target text and library state support it. Ox of Agonas is a rebuild line when immediate Oracle win is not established.
Pilot skill floor: high
No-API allowed: no
Light-model allowed: yes

### Policy: Thassa's Oracle Payoff Target
Priority: High
Decision families: selection, priority
Cards: Dread Return; Thassa's Oracle
Phase windows: resolving Dread Return target prompt, combo finish
Runtime cues: action:target Thassa's Oracle Dread Return
Use when: the legal action text offers Thassa's Oracle as the Dread Return target and the selected line is already a Dread Return payoff attempt.
Avoid when: Thassa's Oracle is not a legal visible target or the engine has not selected the Dread Return payoff line.
Instructions: Select Thassa's Oracle only from explicit legal target text. Do not assume an immediate win without the rules engine resolving the trigger and library state.
Pilot skill floor: low
No-API allowed: yes
Light-model allowed: yes

### Policy: Ox Of Agonas Reload Target
Priority: Medium
Decision families: selection, priority
Cards: Dread Return; Ox of Agonas
Phase windows: Dread Return target prompt, stalled combo turns
Runtime cues: action:target Ox of Agonas Dread Return
Use when: the legal action text offers Ox of Agonas as the Dread Return target and the selected plan is to reload from graveyard resources rather than finish immediately.
Avoid when: Thassa's Oracle is the selected legal payoff line or graveyard resources must be preserved for another visible action.
Instructions: Use Ox of Agonas to convert a stalled graveyard into more cards and dredges. Card text check required for exact escape or draw/discard details at runtime.
Pilot skill floor: medium
No-API allowed: no
Light-model allowed: yes

### Policy: Breakthrough All-In Gate
Priority: Medium
Decision families: priority, mana, selection
Cards: Breakthrough; Lion's Eye Diamond; Golgari Grave-Troll; Stinkweed Imp; Golgari Thug
Phase windows: main phases, early combo turns
Runtime cues: action:cast Breakthrough
Use when: cast Breakthrough when dredgers are available and discarding the hand is acceptable because the spell can generate enough dredge volume now.
Avoid when: the hand contains required sideboard interaction, the only dredger is not yet in graveyard, or a lower-risk enabler is legal and sufficient.
Instructions: Breakthrough is a commitment spell. Use light reasoning for X, mana, stack risk, and whether hand loss still leaves Dread Return or reload access.
Pilot skill floor: high
No-API allowed: no
Light-model allowed: yes

### Policy: Fetch And Color Mana Discipline
Priority: Medium
Decision families: mana
Cards: Polluted Delta; Flooded Strand; Misty Rainforest; Scalding Tarn; Underground Sea; Volcanic Island; Island; Faithless Looting; Careful Study; Otherworldly Gaze; Breakthrough; Cephalid Coliseum
Phase windows: land plays, fetch activations, spell-casting prompts
Runtime cues: action:play; action:activate Polluted Delta; action:activate Flooded Strand; action:activate Misty Rainforest; action:activate Scalding Tarn
Use when: choose lands and colors that cast the current enabler while preserving blue for Cephalid Coliseum and red for Faithless Looting when visible.
Avoid when: fetching a color leaves the current legal enabler uncastable or cuts off known follow-up spells.
Instructions: Prioritize immediate engine access. Do not treat the mana base as generic; this deck needs blue and red at exact moments.
Pilot skill floor: medium
No-API allowed: no
Light-model allowed: yes

### Policy: Combat Default For Combo Bodies
Priority: Low
Decision families: combat
Cards: Narcomoeba; Poxwalkers; Golgari Grave-Troll; Stinkweed Imp
Phase windows: declare attackers, declare blockers, damage steps
Runtime cues: action:attack; action:block
Use when: make combat choices only after checking whether creatures are needed for Dread Return, Cabal Therapy, survival, or lethal pressure.
Avoid when: a creature is required for a visible flashback cost and combat does not prevent lethal or create lethal.
Instructions: Dredge creatures are resources first and attackers second. Stinkweed Imp can block when survival matters, but do not trade away combo bodies casually.
Pilot skill floor: medium
No-API allowed: no
Light-model allowed: yes

### Policy: Unmask Protection And Disruption
Priority: High
Decision families: interaction, selection, sideboard
Cards: Unmask; Cabal Therapy; Lion's Eye Diamond; Dread Return
Phase windows: pre-combo main phases, opening turns, post-board games
Runtime cues: action:cast Unmask; prompt:exile a black card; prompt:choose a nonland card
Use when: use Unmask to clear hate or interaction before committing Lion's Eye Diamond, Breakthrough, Cephalid Coliseum, or Dread Return.
Avoid when: exiling the chosen black card removes the only engine, dredger, or payoff needed for the current visible line.
Instructions: Prefer revealed information and immediate combo protection. Treat pitch choice as strategic because every black card may be engine material.
Pilot skill floor: high
No-API allowed: no
Light-model allowed: yes

### Policy: Answer Visible Hate
Priority: High
Decision families: interaction, priority, sideboard
Cards: Into the Flood Maw; Siege Smash
Phase windows: post-board main phases, priority before engine commitment
Runtime cues: action:cast Into the Flood Maw; action:cast Siege Smash; prompt:choose target
Use when: a visible opposing permanent or object stops graveyard execution and the legal action text offers an answer that can unlock the current or next engine turn.
Avoid when: no legal relevant target is visible or answering now prevents a stronger immediate legal combo line.
Instructions: Into the Flood Maw is for tempo or hate removal when legal. Siege Smash requires card text check required before assuming target types or destruction mode.
Pilot skill floor: high
No-API allowed: no
Light-model allowed: yes

### Policy: Leyline Pregame And Graveyard Mirrors
Priority: Medium
Decision families: pregame, sideboard, mulligan
Cards: Leyline of the Void
Phase windows: pregame, opening hand, sideboarded games
Runtime cues: action:begin with Leyline of the Void; prompt:put Leyline of the Void onto battlefield
Use when: the legal pregame action offers Leyline of the Void from opening hand in a matchup where opposing graveyards matter.
Avoid when: Leyline of the Void is not in opening hand or the matchup plan did not include it.
Instructions: Put Leyline onto the battlefield from explicit legal pregame text. Do not mulligan functional engine hands solely to find it unless matchup guidance says graveyard denial is decisive.
Pilot skill floor: low
No-API allowed: yes
Light-model allowed: yes

### Policy: Sideboard Balance Gate
Priority: Medium
Decision families: sideboard
Cards: Unmask; Into the Flood Maw; Siege Smash; Leyline of the Void; Golgari Grave-Troll; Stinkweed Imp; Golgari Thug; Faithless Looting; Breakthrough; Dread Return; Bridge from Below; Poxwalkers
Phase windows: sideboarding after game 1 or game 2
Runtime cues: prompt:sideboard; action:submit sideboard plan
Use when: choose a legal plan that answers the matchup while preserving dredger density, enabler density, and enough bodies for Dread Return.
Avoid when: adding sideboard cards turns the deck into interaction without a fast graveyard engine.
Instructions: Unmask fights stack or hate, Into the Flood Maw and Siege Smash answer visible hate when appropriate, and Leyline of the Void is for graveyard opponents. Exact sideboard plans must follow Sideboard Map.
