Yummy Deck #770375 — Yu-Gi-Oh! Master Duel

Deck — Deck Power Evaluation

Final Contextual Deck Power: 53/100 (±10 · Confidence: Low)

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

Legality

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

Identity & game plan

• Win condition: Link-1 bootstrap (Yummy monsters summoned off a Link-1 or Level 2 Synchro) into Yummy Synchro/Link boards and Fiendsmith or Sky Striker extra-deck pressure; Fiendsmith's Desirae / Fiendsmith's Lacrima boss with Mignon ATK buffs, backed by Nibiru as a 3000-ATK closer
• Turn 1 (going first): Open a Marshmao or Cooky/Lollipo starter, Special Summon on an empty field, chain a Link-1 (Yummy Snatchy) and go to a Synchro or Link board; hold Ash Blossom, Ghost Belle, and Infinite Impermanence for the first opposing activation
• Turn 2 (going second): Use the 12 hand traps (about 90% at least one in a 6-card hand) to strip the opponent's first board, then rebuild Yummy monsters from the GY through Yummyusment Mignon and the Yummy Way Synchros
• Recovery: Recover from GY via Mignon, Yummy Surprise, and Assist Yummy; Fiendsmith Engraver and Tract add Fiendsmith pieces from the Deck
• After siding: No Side Deck is registered in the export (side_count 0), so there is no post-side plan; best-of-3 play would start from the same main deck

Why it scores here

The deck scores as a system: its 9 Yummy Level-1 starters give about a 74% chance of at least one in a 5-card opening hand and about 81% in a 6-card hand (Inferred hypergeometric), and the archetype core is nearly always present, so the engine opens reliably. Its interaction layer (12 hand traps, about 90% chance of at least one going second, plus negation text on Desirae, Dominus Purge and Forbidden Droplet) is the strongest part of the system and drives the interruption-resilience and going-second scores. Conversion is the weak point: no recorded boards exist, so the combo ceiling and median are text-only inferences, and the extra deck mixes Yummy Way Synchros, Fiendsmith and Sky Striker Links that compete for the same Link-1 and Level 2 bootstrap. Popularity was not credited: the Yummy archetype's usage stats confirm a real list, but the 32.7% exact-name purity and 9 off-archetype main-deck families lower the score. Card scores were not averaged or summed; the score comes from consistency, median output and interaction on the whole system, with a moderate penalty for engine conflicts and the absence of a Side Deck.

Dimension scores

How the score was computed

Strategy profile: 0.85 Combo + 0.15 Midrange (approximate; Combo profile used for dimension weights). Structural ≈ 60, Going First ≈ 57, Going Second ≈ 62, Meta = provisional, Tournament Reliability ≈ 52. Modifiers: engine conflicts (-3); no side deck (-2); banlist exposure (0). Final formula: 0.80*Structural + 0.20*TournamentReliability (Meta provisional); Structural = 59.71 from the Combo profile, TR 52, then modifiers total -5 = 53

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

• Opening starter density: about 74% at least one of 9 Yummy monsters in 5 cards and about 81% in 6, with the archetype core almost always present
• Dense interaction: 12 hand traps give about 90% at least one going second, plus negation and removal text on Desirae, Dominus Purge and Forbidden Droplet
• Multiple independent starters (Marshmao, Cooky, Lollipo, Cupsy, Fiendsmith Engraver) rather than one choke-point card
• Strong closing options: Nibiru 3000 ATK, Desirae 2800 ATK, Mignon ATK buff

Weaknesses

• No recorded boards, so ceiling and median are unmeasured
• Low exact-name purity (32.7%) with 9 off-archetype families and a splash-heavy Extra Deck
• No Side Deck (side_count 0) and no post-side plan
• Heavy Link-1 and Synchro sequencing, so the pilot needs many decisions per turn

Critical choke points

• Link-1 bootstrap: Snatchy (2 copies) and the other Link-1s must be live before the Yummy Way Synchros work
• Hand traps need a monster or Spell/Trap on the field to activate, so a 0-card board can stall them

Recommended changes

Evidence & confidence

• Verified: Legal size and copy counts for Master Duel (40 main, 15 extra, 0 side); Banlist: Cupsy Yummy, Maxx C and Hornet Drones Limited at 1 copy; Marshmao Semi-Limited at 2 copies; Archetype purity 32.7% and 37 off-archetype copies from the composition block; Usage statistics: 23 rows, 12 core cards present (52.2%)
• Inferred: P(at least one Yummy starter) = 0.74 in 5 cards, 0.81 in 6 cards (hypergeometric); Hand-trap density gives about 90% at least one going second; Interaction layering and Desirae/Lacrima/Nibiru closing power read from card text; Link-1 bootstrap dependency and engine conflict read
• Provisional: Meta power and matchup fit (no dated metagame sample or tournament link); Side-deck adaptability (no Side Deck present); Combo median and ceiling (no recorded boards)
• Data gaps: no combos supplied: combo floor, median and ceiling are text-only inference no tournament link: archetype meta-share and pilot match record are absent no win-rate telemetry (going-first/second, matchup, brick and starter rates) Meta Power is Provisional unless a dated metagame sample is supplied no Side Deck in the export (side_count 0) no guides attached (total_guides 0)
