Yummy Deck #766309 — Yu-Gi-Oh! Master Duel

Deck — Deck Power Evaluation

Final Contextual Deck Power: 51/100 (±10 · Confidence: Low)

• Primary strategy: Combo
• Secondary strategies: Stun, Toolbox
• Format: master-duel

Legality

Main 40 / Extra 15 / Side 0 — status: Legal.

Identity & game plan

• Win condition: Link-1 or Level-2 Synchro enabler into Yummy Way Synchros and Fiendsmith's Desirae / D/D/D Wave High King Caesar boss monsters; Fiendsmith's Lacrima ATK reduction and Yummyusment field-spell ATK boosts converting a board into attack
• Turn 1 (going first): Open a Yummy starter (Cooky, Marshmao, Lollipo, Cupsy), summon a Link-1 or Level-2 Synchro to unlock Yummy Special Summons, then build a board with Yummy Way Synchros
• Turn 2 (going second): Use hand traps (Ash Blossom, Ghost Belle, Effect Veiler, Infinite Impermanence, Droll & Lock Bird) to answer the opponent's first board, then rebuild through the Yummy engine
• Recovery: Rebuild from the GY using Marshmao and Fiendsmith Engraver GY effects, and Mulcharmy Fuwalos draw effects
• After siding: No side deck is registered, so there is no post-side plan in the list as submitted

Why it scores here

The deck reliably opens a Yummy starter about 64% of the time in a 5-card hand and about 65% in a 6-card hand, and the archetype core is almost always present, so the engine is accessible in principle. Its strongest signal is interaction: 15 hand traps, 16 negation-text cards and 15 removal-text cards give high going-second coverage, with about 95% odds of at least one hand trap in six cards. Conversion is weaker because no recorded boards exist, so the ceiling and median are read from card text only and labeled Inferred. Four archetype sub-engines (Yummy, Fiendsmith, Mulcharmy, Sky Striker) plus Dominus and D/D cards are partly in conflict, and the list has no side deck, which lowers resilience and post-side scores. Popularity in the usage statistics confirms the core is a real, accessible list, but it did not earn points on its own, and the score was built from the deck-level dimensions, not by averaging card scores.

Dimension scores

How the score was computed

Strategy profile: Combo. Structural ≈ 59, Going First ≈ 56, Going Second ≈ 62, Meta = provisional, Tournament Reliability ≈ 50. Modifiers: engine conflicts (-3); weak post-side plan (-2); banlist exposure (-1). Final formula: 0.80*Structural + 0.20*TournamentReliability (Meta provisional) + ContextModifiers = 0.80*58.7 + 0.20*50 - 6 ≈ 51

Probability & combo summary

• Opening a starter: P(≥1) ≈ 0.64 · key two-card combo ≈ — · full-brick estimate ≈ — (all Inferred)
• Combo output: best PowerIndex —, median —, board-per-starter —
• Turn order: 0 going-first lines vs 0 going-second lines

Strengths

• Very high hand-trap and negation density gives strong going-second interaction
• Core Yummy archetype cards are almost always present, so the engine is accessible
• Multiple recursion and search routes give resilience after one interruption
• Strong end-board boss options in the Extra Deck (Desirae, Caesar, Lacrima)

Weaknesses

• Four archetype sub-engines split the deck and reduce coherence
• No side deck, so there is no post-side plan
• No recorded combos, so conversion and median output are unverified
• Several one-copy tech and off-archetype cards may bricks or dilute the starter count

Critical choke points

• Yummy Special Summon requires a Link-1 or Level-2 Synchro on the field, and the Link-1 enablers are few (Snatchy x2, Requiem, Kagari)
• Opening without a Yummy starter leaves the hand dependent on hand traps

Recommended changes

Evidence & confidence

• Verified: List is legal: 40 Main, 15 Extra, 0 Side within the Master Duel size rules; Limited and Semi-Limited copy counts are within legal limits; Archetype core inclusion rates from usage statistics (Yummy core 100%); Hypergeometric draw probabilities from the resolved Main Deck
• Inferred: Consistency estimates (starter access, hand-trap access going second) from hypergeometric odds and card text; Interaction quality from negation and removal card text; Engine conflict and pilotability from archetype spread and effect structure; Going-first and going-second power from the component dimensions
• Provisional: Matchup and format fit (no tournament data or dated meta sample); Post-side plan (no side deck)
• Data gaps: no combos supplied; combo floor, median and ceiling are text-only inference no tournament link; archetype meta-share and per-pilot match record are absent no win-rate telemetry; going-first, going-second, matchup and brick rates are Inferred or Unknown Meta Power is Provisional because no dated metagame sample was supplied no side deck is registered, so post-side adaptation cannot be evaluated no guides attached to the archetype
