Yummy Deck #765341 — Yu-Gi-Oh! Master Duel

Deck — Deck Power Evaluation

Final Contextual Deck Power: 58/100 (±6 · Confidence: Medium)

• Primary strategy: Midrange
• Secondary strategies: Stun, Synchro, Link
• Format: master-duel

Legality

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

Identity & game plan

• Win condition: Synchro and Link boards (Zalen, Fydraulis Harmonia, Nibiru, Wind Pegasus) built from Yummy starters, closed by Yummy field-spell ATK boosts; Yummy field spells and recursion (Yummyusment Mignon, Yummy Surprise) grinding the GY back into the field
• Turn 1 (going first): Open a LIGHT Beast Level 1 starter (Marshmao can Special Summer from hand onto an empty board), Link Summon Yummy Snatchy or Linkuriboh as the first enabler, then Special Summon Lollipo or Cooky into a Synchro or Link Level 2 route
• Turn 2 (going second): Hold Infinite Impermanence, Ash Blossom, Droll and Maxx C to stop the opponent's first engine, then rebuild through Yummy monsters from the GY
• Recovery: Mulcharmy draws, Yummy field spells that re-summon from the GY, and multiple Level 1 starters allow rebuilding after a single removal or hand-trap exchange
• After siding: No side deck is registered (side count 0), so there is no post-side plan in the supplied list

Why it scores here

The deck reliably opens through its nine Yummy LIGHT Beast Level 1 starters: hypergeometric odds put at least one of them in a going-first 5-card hand at about 0.74, with Marshmao able to start from an empty board and feed the first Link-1 enabler. Interaction is the strongest part of the system: ten hand traps and eleven negation-text cards give about 0.85 odds of at least one hand trap in a going-second 6-card hand, and this drives the going-second score. Conversion and floor output could not be measured because no recorded boards were supplied, so the combo scores rest on card-text reads and are Inferred. The score is not driven by Yummy's popularity, since usage statistics only confirm the list is a real, accessible core build; the score comes from consistency, interaction and resilience on the system, not from averaging the card scores. The absence of a side deck and the going-first hand-trap brick risk pull the score down, and Meta Power stays provisional.

Dimension scores

How the score was computed

Strategy profile: Midrange. Structural ≈ 62, Going First ≈ 58, Going Second ≈ 68, Meta = provisional, Tournament Reliability ≈ 56. Modifiers: banlist_exposure (-2); engine_dilution (-1). Final formula: 0.80*Structural + 0.20*TournamentReliability (Meta provisional) + ContextModifiers = 0.80*62 + 0.20*56 - 3 = 57.8, rounded to 58

Probability & combo summary

• Opening a starter: P(≥1) ≈ 0.74 · 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

• Ten hand traps give 0.85 odds of at least one in a going-second 6-card hand (Inferred)
• Nine Level 1 LIGHT Beast starters across Lollipo, Cooky, Marshmao and Cupsy give redundancy (Inferred)
• Compact 21-distinct-card Main Deck with nine singletons (Verified)

Weaknesses

• No side deck, so no post-side adaptability (Verified)
• No Link-1 or Level 2 Synchro is in the Main Deck, so the first enabler must come from Marshmao or an Extra Deck Link-1 (Inferred)
• Hand-trap-heavy opening hands can brick on going first, since Dominus Spark and Dominus Purge need opponent action (Inferred)
• Only 17 of 55 cards are exact-name Yummy, so the engine is diluted (Verified)

Critical choke points

• Marshmao (2 copies) or another LIGHT Beast Level 1 to enable the first Link-1 summon
• Maxx C, Cupsy Yummy and Crossout Designator (each one copy, Limited) are single-copy interaction and starter pieces

Recommended changes

Evidence & confidence

• Verified: Legality: Legal, 40 Main, 15 Extra, 0 Side; all restricted cards within legal copies; Copy histogram and Extra Deck breakdown from the composition block; Hypergeometric probabilities for copies and hand sizes
• Inferred: Starter access and bootstrap order (Marshmao to Snatchy to Lollipo or Cooky); Hand-trap interaction and going-second strength; Consistency, brick risk and resilience scores; Combo ceiling and floor from card-text reads only
• Provisional: Meta Power (null) and matchup fit; Tournament reliability and archetype share (no tournament link)
• Data gaps: No recorded combos supplied; combo ceiling, median and floor are text-only inference No tournament link; archetype meta-share and per-pilot match record absent No win-rate telemetry; going-first, going-second and matchup rates unknown No side deck, so post-side performance is unscored usage_statistics marks several Extra Deck cards as missing (Yummy Snatchy, Herald of the Arc Light, Linkuriboh, Cupsy Yummy Way, Lollipo Yummy Way, Cooky Yummy Way, I:P Masquerena, Spright Elf) even though the Extra Deck list contains them; core_present_pct 56 is likely understated Meta Power is Provisional unless a dated metagame sample is supplied
