| Meta Power | provisional |
| Tournament Reliability | 44 |

Legality
Main 40 / Extra 15 / Side 0 — status: Legal.
Identity & game plan
- Win condition: Synchro and Link boards of LIGHT Beasts boosted by Yummyusment☆Mignon, closed by Zalen, Wind Pegasus or Golden Cloud Beast - Malong; Yummy GY recursion (Mignon, Acroquey, Yummy☆Surprise) rebuilding the board after interaction
- Turn 1 (going first): T1 Marshmao☆Yummy or Jester Confit; Link-1 (Linkuriboh or Yummy★Snatchy) enables Lollipo/Cooky/Cupsy hand-summons into a Yummy Way Synchro (Inferred)
- Turn 2 (going second): Six-card hand with hand traps (Ash, Impermanence, Droll, Maxx C) to stop the opponent's first engine, then a Synchro or Link follow-up (Inferred)
- Recovery: Yummy GY effects (Mignon, Acroquey, Surprise) and Marshmao/Cupsy searches re-establish Link-1 and Yummy monsters (Inferred)
- After siding: No side deck (0 cards): no post-side plan exists
Why it scores here
The deck reliably offers interaction: ten hand traps, Dominus Spark and Purge, Forbidden Crown and Droplet, and Zalen and Herald negations give it strong answers to a board, which drives the highest dimension (D7). Its engine is less reliable. Only Marshmao☆Yummy and Jester Confit can start from hand with no board, giving roughly 43% chance of at least one going first and about 49% going second, and Yummy hand-summons depend on a Link-1 that exists only in the Extra Deck. Combo data is absent, so ceiling and median are inferred from card text, not observed boards. The score comes from interaction and resilience on the system, not from the Forbidden or Yummy name, and not from averaging card scores. Meta share is unavailable and the deck has no side, so it cannot be scored on matchup fit or adaptation.
Dimension scores
| # | Dimension | Score | Evidence |
|---|---|---|---|
| D1 | Engine Accessibility & Consistency | 45 | P(≥1 of Marshmao/Jester in a 5-card opening hand) ≈ 0.43 from 4 copies (hypergeometric); ≈0.49 going second; Link-1 gating unresolved (Inferred) |
| D2 | Opening-Hand Quality & Brick Management | 40 | 17 non-monster slots and 10 hand traps that need opponent cards or board; 23 monsters with conditional summons give high dead-hand risk (Inferred) |
| D3 | Combo Conversion & Ceiling | 58 | No parseable boards; ceiling inferred from Mignon's ATK boost and Yummy Way Synchro text only (Inferred) |
| D4 | Combo Floor & Median Output | 42 | No recorded boards for a median; floor inferred from ~43% starter access and conditional summons (Inferred) |
| D5 | Interruption Resilience & Route Redundancy | 58 | Two independent 1-drop starters, Yummy GY recursion (Mignon, Acroquey, Surprise), and several hand traps (Inferred) |
| D6 | Resource Economy, Recovery & Grind | 60 | Yummy searchers (Cupsy, Marshmao) and GY recursion offset Piri Reis's LP cost; no resource telemetry (Inferred) |
| D7 | End-Board & Interaction Quality | 75 | 10 hand traps plus Dominus Spark/Purge, Forbidden Crown/Droplet, Zalen and Herald negations; semantic read from card text (Inferred) |
| D8 | Going-Second & Board-Breaking Power | 68 | Going-second hand traps and Crown/Droplet/Crossout answer an established board; no going-second split data (Inferred) |
| D9 | Offensive Pressure & Closing Power | 55 | Synchro Yummy Way and Zalen/Pegasus/Malong ATK 1200–2800; Mignon ATK boost; no end-board observations (Inferred) |
| D10 | Main Deck Efficiency & Flexibility | 55 | 40/40 main, 21 distinct, 9 singletons, 17 non-monster slots, exact-name archetype purity 3.6% (Verified) |
| D11 | Extra Deck Efficiency & Coverage | 52 | 15 Extra (9 Synchro, 6 Link); about 7 Yummy-linked Extra cards, with Pegasus, Malong, Zalen, Shamisen and Spright Elf off-theme (Inferred) |
| D12 | Side Deck Adaptability | 20 | Side deck is 0 cards, so there is no post-side adaptation (Verified) |
| D13 | Matchup Coverage & Format Fit | 50 | tournament_context unavailable and no archetype meta-share; neutral placeholder excluded from Structural (Provisional) |
| D14 | Pilotability & Error Tolerance | 50 | Multiple conditional hand-summons, chained Link→Synchro sequences and once-per-turn effects (Inferred) |
How the score was computed
Strategy profile: 0.75 Midrange + 0.25 Stun; D13 dropped and renormalised over 92.75. Structural ≈ 54, Going First ≈ 56, Going Second ≈ 60, Meta = provisional, Tournament Reliability ≈ 44. Modifiers: engine_conflict (-4); unrecoverable_choke_point (-2). Final formula: 0.80*Structural + 0.20*TournamentReliability + ContextModifiers (Meta provisional; D13 excluded from Structural) = 0.80*54 + 0.20*44 − 6 = 46
Probability & combo summary
- Opening a starter: P(≥1) ≈ 0.43 · 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 plus Dominus Spark/Purge and Forbidden Crown/Droplet give broad interaction
- Two independent 1-drop starters (Marshmao, Jester) and Yummy GY recursion give some route redundancy
- Legal under master-duel rules: all Limited and Semi-Limited copy counts are respected
Weaknesses
- Only about 43% chance of a usable 1-drop starter in a going-first hand
- Yummy hand-summons are gated by a Link-1 that exists only in the Extra Deck
- Exact-name archetype purity of 3.6%; the deck is a mix of Yummy, Forbidden, Dominus and generic cards
- No side deck, so no post-side plan
Critical choke points
- A Link-1 on field is required for Lollipo/Cooky/Cupsy hand-summons (Yummy★Snatchy and Linkuriboh are Extra-only)
- Marshmao or Jester must be drawn for a reliable opening
Recommended changes
| Priority | Remove | Add | Reason |
|---|---|---|---|
| 1 | Golden Cloud Beast - Malong | A Yummy-linked Extra Deck Synchro or Link (e.g. a second Link-1 enabler) | Reduces off-theme Extra slots and gives the Link-1 gate a second Extra-Deck route (Inferred) |
| 2 | Nibiru, the Primal Being | Side deck of 8–15 cards | Nibiru needs 5 opponent summons to activate; a side deck gives the deck the post-side plan it currently lacks (Inferred) |
Evidence & confidence
- Verified: Legal under master-duel size and copy limits; restricted cards within legal copies; Card text for Yummy hand-summon conditions and hand-trap effects; Side count is 0; Archetype purity 3.6%
- Observed: Usage stats show 60% core presence, but only against the Main Deck (see data_gaps)
- Inferred: Starter access, brick rate and interaction density from hypergeometric and text reads; Going-first and going-second estimates; Ceiling and median from text only
- Provisional: Meta Power (null); D13 matchup and format fit (neutral placeholder, excluded from Structural)
- 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 absent No win-rate telemetry: going-first/second, matchup and brick rates are Inferred or Unknown Meta Power is Provisional unless a dated metagame sample is supplied Usage stats flag Extra Deck cards (Spright Elf, Snatchy, Linkuriboh, Herald, the Yummy Way Synchros) as in_this_deck:false although they are present in the Extra list; the usage check appears to consider only the Main Deck, so the core-presence 60% figure is understated Archetype core probability (0.997) groups generic cards with the Yummy engine and is not used
