Yummy Deck #759349 — Yu-Gi-Oh! Master Duel

Deck — Deck Power Evaluation

Final Contextual Deck Power: 53/100 (±8 · Confidence: Medium)

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

Legality

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

Identity & game plan

• Win condition: Snatchy Link-1 enables hand-Summons of Lollipo, Cooky and Cupsy, which chain into Level 2 Synchro Ways (Cooky Way 1600 ATK, Lollipo Way 1200 ATK) and Link boards such as W:P Fancy Ball (2400 ATK) to pressure the opponent.; Hand-trap-supported control of the opponent's first Main Phase (Infinite Impermanence, Ash Blossom, Droll and Lock Bird, Maxx C, Effect Veiler) buys time for the Yummy engine to go off.
• Turn 1 (going first): Open Marshmao (hand-Summonable with no monsters on field), Link Summon Yummy Snatchy from it, then hand-Summon Lollipo, Cooky or Cupsy and build a Synchro or Link board. Only about a quarter of going-first hands contain a Marshmao, so this line is not reliable.
• Turn 2 (going second): Hold 2 to 3 hand traps (Ash Blossom, Infinite Impermanence, Droll and Lock Bird) to answer the opponent's first summon or search, then rebuild the Yummy board from the GY and Extra Deck.
• Recovery: Recover through GY-based Yummy effects (Marshmao adds a Yummy Spell/Trap from GY, Yummyusment Mignon and Assist Yummy can return from GY), Witchcrafter Creation recursion, and Link-1 redundancy (Artemis, Linkuriboh, Almiraj, Link Spider).
• After siding: Not available: the deck has no side deck (side_count 0), so there is no recorded post-side plan.

Why it scores here

The deck opens a functional plan reasonably often because the exact-name core is heavily represented and the Yummy engine has several Link-1 and Level 2 Synchro routes once a board exists. Its real conversion comes from Lollipo, Cooky and Cupsy hand-Summons that feed Synchro Ways and Link monsters, which gives it a strong ceiling, but no recorded boards exist to measure its median output. Its heaviest strength is interaction: ten hand traps and several Quick negates give it multiple layers of disruption, which carries the score above what consistency alone would support. Consistency is capped by the fact that the only hand-startable starter is Marshmao, with about a 24% chance of appearing in a going-first opener, and by roughly 15 spell and trap slots that are dead without a board. The score is not an average of card scores, and popularity did not earn points: the Yummy archetype's usage statistics confirm the list is real, not that it is strong. Missing side deck, Limited-status key cards and a single-starter bootstrap all pull the final score down.

Dimension scores

How the score was computed

Strategy profile: Combo. Structural ≈ 62, Going First ≈ 60, Going Second ≈ 70, Meta = provisional, Tournament Reliability ≈ 52. Modifiers: Banlist exposure (-2); Empty side deck (-3); Single-starter bootstrap (-2). Final formula: 0.80*Structural + 0.20*TournamentReliability + ContextModifiers (Meta provisional); 0.80*61.74 + 0.20*52 - 7 = 52.8 → 53

Probability & combo summary

• Opening a starter: P(≥1) ≈ 0.24 · 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 and multiple Quick negates give layered interaction on the opponent's first turn
• Multiple Link-1 and Level 2 Synchro routes give redundancy for the Yummy hand-Summon engine
• Strong Synchro and Link boards (Cooky Way 1600, Fancy Ball 2400) once the engine is live

Weaknesses

• Only Marshmao starts the engine from an empty hand, so the T1 line is fragile
• Empty side deck: no post-side plan
• About 15 Main Deck spell and trap slots are dead or conditional on the board

Critical choke points

• Marshmao (2 copies) as the only hand-startable starter
• Yummy Snatchy as the Link-1 enabler for the Yummy hand-Summon chain

Recommended changes

Evidence & confidence

• Verified: Main 40 and Extra 15 are within the master-duel size rules (main 40-60, extra 0-15); All Limited and Semi-Limited copy counts are legal (Maxx C 1, Crossout 1, Cupsy 1, Herald 1, Droll 2, Marshmao 2); Side deck is empty (side_count 0); Hypergeometric draw values match the stated 40-card main deck
• Observed: Usage statistics show the Yummy archetype's standard core is present (12 of 23 stat rows, with Extra-Deck rows flagged absent despite being in the list)
• Inferred: Consistency and brick estimates from hypergeometric odds and text; Interaction density and layering from negation and removal text; Going-first and going-second power split; Starter bootstrap through Marshmao and Link-1 routes
• Provisional: Meta Power (null, no dated metagame sample); D13 matchup and format fit (no tournament link)
• Data gaps: No combos supplied: combo floor, median and ceiling are text-only inference Usage statistics mark every Extra Deck core card (Lollipo Way, Cupsy Way, Cooky Way, Herald, Linkuriboh, S:P Little Knight, Snatchy, Spright Elf) as in_this_deck false, but the card list contains them. The usage in_this_deck flag is unreliable for the Extra Deck, so core_present_pct 52.2 is understated. No tournament link: archetype meta-share and per-pilot record absent No win-rate telemetry (going-first/second, matchup, brick, starter, OTK rates) Meta Power is Provisional unless a dated metagame sample is supplied Deck title is null
