Legality

Main 56 / Extra 15 / Side 0 — status under the rules at evaluation time: Illegal. 1 violation(s).

Identity & game plan

  • Win condition: Control / Disruption
  • Turn 1 (going first): Set hand traps (Infinite Impermanence, Ash Blossom, Ghost Belle) and search for Yummy or Mimighoul pieces; aim to establish a disruptive board before opponent can develop.
  • Turn 2 (going second): Use hand traps to negate opponent's key plays, then summon Yummy/PSY‑Frame monsters to apply pressure.
  • Recovery: Draw engines with Mulcharmy Fuwalos, Droll & Lock Bird and recycle banished cards via Called by the Grave.
  • After siding: No side deck; rely on hand‑trap density and flexible searchers to adapt.

Why it scores here

The deck is illegal because it runs three copies of the limited Cupsy☆Yummy, which alone forces a low overall rating. Its engine is highly fragmented across Yummy, Mimighoul, PSY‑Frame and generic hand‑trap tools, giving poor starter consistency and a high brick probability. While it fields many negation and draw effects, the lack of a coherent win‑condition and the absence of a side deck limit its ability to recover from disruption. Consequently the structural and tournament reliability scores are low, and the final contextual power reflects the deck’s theoretical potential rather than practical playability.

Dimension scores

# Dimension Score Evidence
D1 Engine Accessibility & Consistency 30 P(at least one starter such as Infinite Impermanence or Ash Blossom) ≈ 0.25; many starters require specific board states (Inferred)
D2 Opening-Hand Quality & Brick Management 25 High copy of Cupsy☆Yummy and many conditional summons create brick risk (Inferred)
D3 Combo Conversion & Ceiling 40 No recorded combo boards; best plausible line limited to hand‑trap lock + single Yummy summon (Inferred)
D4 Combo Floor & Median Output 30 Typical games will only achieve a single hand‑trap chain; median output low (Inferred)
D5 Interruption Resilience & Route Redundancy 45 Abundance of hand traps (Infinite Impermanence, Ghost Belle, Droll) gives some resilience (Inferred)
D6 Resource Economy, Recovery & Grind 55 Draw engines (Mulcharmy Fuwalos, Droll) and recycle via Called by the Grave improve economy (Inferred)
D7 End-Board & Interaction Quality 50 Interaction density moderate (multiple negations, but few high‑impact boss monsters) (Inferred)
D8 Going-Second & Board-Breaking Power 40 Going‑second pressure relies on hand traps; lacks dedicated board‑breakers (Inferred)
D9 Offensive Pressure & Closing Power 35 No high‑ATK boss monsters; closing power rests on incremental advantage (Inferred)
D10 Main Deck Efficiency & Flexibility 30 56‑card main deck with only 2.8% archetype purity; many off‑archetype cards dilute efficiency (Inferred)
D11 Extra Deck Efficiency & Coverage 35 15‑card extra deck spread across many types without a clear focal point (Inferred)
D12 Side Deck Adaptability 10 Side deck empty; no post‑side adaptation plan (Inferred)
D13 Matchup Coverage & Format Fit 20 No tournament or meta data; matchup fit unknown (Provisional)
D14 Pilotability & Error Tolerance 30 Complex multi‑step hand‑trap chains and many limited cards raise error tolerance (Inferred)

How the score was computed

Strategy profile: Toolbox. Structural ≈ 36.1, Going First ≈ 30, Going Second ≈ 30, Meta = provisional, Tournament Reliability ≈ 30. Modifiers: Illegal overcopy penalty (-10); Low archetype purity (-5). Final formula: 0.80*Structural + 0.20*TournamentReliability (Meta provisional)

Probability & combo summary

  • Opening a starter: P(≥1) ≈ — · 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

  • Rich hand‑trap suite for disruption
  • Multiple draw and recycle effects

Weaknesses

  • Illegal overcopy of Cupsy☆Yummy
  • Fragmented engine with low archetype purity
  • No side deck for adaptation

Critical choke points

  • Cupsy☆Yummy copy limit violation
  • Reliance on specific Link‑1 or Level‑2 Synchro conditions
Priority Remove Add Reason
1 Cupsy☆Yummy (extra copies) Legal Yummy engine pieces (e.g., Yummy★Snatchy, Yummy☆Surprise) Bring deck into legal range and improve engine consistency
2 Off‑archetype filler cards Core Archfiend tools (Royal Archfiend, Fiendsmith's Sequence, etc.) Increase archetype purity and create a focused win condition

Evidence & confidence

  • Verified: Legality status and copy limits; Card text excerpts for each listed card
  • Inferred: All dimension scores derived from card roles, probabilities and deck composition; Engine accessibility, brick risk, resource economy, interaction quality
  • Provisional: Matchup and meta fit due to lack of tournament data
  • Data gaps: no combos supplied — combo floor/median/ceiling is text-only inference no tournament link — archetype meta-share and per-pilot match record absent no win-rate telemetry exists in YGOVN (going-first/second, matchup, game-level, brick/starter/OTK rates) — those signals are Inferred or Unknown Meta Power is Provisional unless a dated metagame sample is supplied
