Yummy Deck #766489 — Yu-Gi-Oh! Master Duel

Deck — Deck Power Evaluation

Final Contextual Deck Power: 57/100 (±8 · Confidence: Medium)

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

Legality

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

Identity & game plan

• Win condition: Link and Synchro end-board built from Yummy Level-1 starters (Yummy Snatchy link chain into the Level-2 Yummy Way synchros), with Yummyusment Mignon ATK pumping and Imperial Dragon / Fancy Ball as closers.; Primite Dragon Nether Berzelius Fusion off Primite Fusion, using the two Normal Monsters in the Main Deck.
• Turn 1 (going first): Open a Level-1 Yummy starter (Lollipo, Cooky, Marshmao, Cupsy), go to a Link-1 (Snatchy or Striker Dragon) and then a Level-2 Yummy Way synchro; keep Ash Blossom or Ghost Ogre up as the protected interaction.
• Turn 2 (going second): Hold a six-card hand with hand traps (Ash, Ghost Ogre, Ghost Mourner, Droll, Maxx C, PSY-Frame Gamma) to answer the opponent's first summon or activation, then convert the open field into a synchro or link board.
• Recovery: Yummy monsters recur from the GY through Yummy Snatchy and Yummy Surprise, and Cupsy/Marshmao search a Yummy Spell/Trap back from the GY.
• After siding: Not applicable: Master Duel has no Side Deck and this list runs 0 side cards, so there is no post-side plan.

Why it scores here

The deck reliably opens an archetype starter: nine Level-1 Yummy monsters in the Main Deck give roughly a 0.74 chance of at least one in an opening hand of five (hypergeometric, Inferred), and the 20-copy archetype core is present in about 98% of opening hands. Its Link-1 and Level-2 Yummy Way synchro engine converts that opening into a board, with Yummy Snatchy and Yummy Surprise recurring from the GY for the rest of the game. Interaction is the strongest part of the system: ten hand traps and sixteen removal or negation-text cards give about an 85% chance of a hand trap when going second (Inferred), which supports the going-second score. The score does not come from Yummy being a popular archetype, and it does not come from averaging individual card scores. The list carries 38 off-archetype copies (31% exact-name purity) and only two Normal Monsters for its Primite lines, so engine conflicts pull down consistency and efficiency. No board data, tournament link, or side deck exists, so the ceiling and median are text-only inference and the post-side score stays low.

Dimension scores

How the score was computed

Strategy profile: Combo. Structural ≈ 62, Going First ≈ 58, Going Second ≈ 66, Meta = provisional, Tournament Reliability ≈ 58. Modifiers: banlist exposure (-1); engine conflicts (-2); dependence on extra-deck link-1 (-1). Final formula: 0.80*Structural + 0.20*TournamentReliability (Meta provisional) + ContextModifiers; 0.80*61.74 + 0.20*58 = 60.99, then -4 modifiers = 57

Probability & combo summary

• Opening a starter: P(≥1) ≈ 0.74 · key two-card combo ≈ — · full-brick estimate ≈ 0.02 (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 and multiple negation-text cards give going-second interaction
• Nine Yummy Level-1 starters give high archetype core access in opening hands
• Recursion through Yummy Snatchy, Yummy Surprise and searchers gives a grind route

Weaknesses

• 31% exact-name purity; the Primite and Mulcharmy blocks compete with the Yummy board
• Only two Normal Monsters for the Primite engine
• No side deck; no post-side adaptation

Critical choke points

• A Link-1 on the field is required for Yummy starter Special Summons; the extra-deck link-1s are the only route
• Two Yummy Way synchros depend on a single Level-1 tuner plus a Link-1

Evidence & confidence

• Verified: Legal status and size (40 Main, 15 Extra, 0 Side) under the master-duel rules; Copy counts and banlist status of all restricted cards; Archetype purity 30.9% and the copy histogram; Hypergeometric draw probabilities as computed in the evidence pack
• Inferred: Engine consistency (D1) and brick management (D2); Going-second interaction density (D7, D8) from card text; Combo ceiling and median from card text only (D3, D4)
• Provisional: Meta Power (null) and matchup fit (D13); Post-side adaptability (D12) given no side deck
• Data gaps: No combos supplied (total_combos 0): combo floor, median and ceiling are text-only inference No tournament link: archetype meta-share and per-pilot record absent No win-rate telemetry: going-first/second, matchup and brick rates are Inferred or unknown usage_statistics in_this_deck flags read false for Extra-Deck cards that the card list does run (Yummy Snatchy, Lollipo Way, Cooky Way, Herald, Cupsy Way); core coverage is understated, so the usage-based core read should be treated with caution Meta Power is Provisional: no dated metagame sample supplied
