Identity & game plan

  • Win condition: White Forest combo via Witch/Silvy/Snake-Eyes recursion and spell/trap synergy; OTK through Diabellstar/Chaos Angel big plays
  • Turn 1 (going first): Set up hand traps and searchers (Ash Blossom, Infinite Impermanence, Maxx C), pop key traps, then assemble White Forest/Snake-Eyes board for combo or big OTK
  • Turn 2 (going second): Use 6-card hand to find Ash Blossom/Maxx C, answer threats with Droll & Lock Bird/Crossout Designator, then pivot to combo or counter OTK
  • Recovery: Return-from-GY recursion (Silvy, Tales) and hand-trap loops to rebuild after disruption

Why it scores here

The deck runs a consistent White Forest/Snake-Eyes engine with strong combo ceiling (D3 75) but a brick-prone, low-consistency floor (D4 50). Hand quality is fragile (D2 55) and disruption resilience is moderate (D5 65). Resource grind is light and side options are weak (D6/D12 low), while interaction and endboard pressure are solid (D7 70, D9 65). Overall score reflects a high-variance combo deck that can reach strong OTK turns but struggles with consistency and matchup variance.

Dimension scores

# Dimension Score Evidence
D1 Engine Accessibility & Consistency 60 Core present 68% and P(at-least-one) 0.9985 for archetype core, but 8 key cards missing from core (Inferred)
D2 Opening-Hand Quality & Brick Management 55 Brick risk elevated: 3 one-copies and 8 three-copies create redundancy issues; hand traps 9 but only 22% in 2-card line (Inferred)
D3 Combo Conversion & Ceiling 75 Best line includes Diabellstar 3000/2500 plus board clear and OTK potential (Observed from card texts and high ATK totals)
D4 Combo Floor & Median Output 50 Median output limited by combo incompleteness and missing core; no parsed boards submitted (Inferred)
D5 Interruption Resilience & Route Redundancy 65 Multiple hand traps and 2 disruption cards (Droll, Crossout) provide route redundancy (Inferred)
D6 Resource Economy, Recovery & Grind 55 Resource signature lean: 12 Spells/13 Spells+Traps, no clear sustain or draw beyond initial setup (Inferred)
D7 End-Board & Interaction Quality 70 Strong endboard presence: 10+ removal/interaction cards including 3 copies of key negates (Observed from card text roles)
D8 Going-Second & Board-Breaking Power 60 Going-second plan present with 6-card hand quality and counter traps, but breaker density modest (Inferred)
D9 Offensive Pressure & Closing Power 65 High-ATK threats (Diabellstar 3000, Chaos Angel 3500, Dark Magician of Destruction 2800) support closing (Observed)
D10 Main Deck Efficiency & Flexibility 60 Deck uses 25 distinct cards with 42 main cards and 15 extras; efficient but not ultra-tight (Inferred)
D11 Extra Deck Efficiency & Coverage 70 Extra deck filled with 15 Synchro/Fusion, many high-impact targets (Observed)
D12 Side Deck Adaptability 40 Side deck absent; no post-side plan data and 8 missing core cards reduce adaptability (Inferred)
D13 Matchup Coverage & Format Fit 50 No tournament data; archetype meta-share unknown and format fit provisional (Provisional)
D14 Pilotability & Error Tolerance 55 Combo steps moderate with 16 searchers and 12 negations; pilotability average for experienced players (Inferred)

How the score was computed

Strategy profile: Balanced (combo-biased). Structural ≈ 68, Going First ≈ 62, Going Second ≈ 64, Meta = provisional, Tournament Reliability ≈ 45. Modifiers: missing_core_impact (-5); hand_trap_protection (3); no_side_deck (-4). Final formula: 0.80*Structural + 0.20*TournamentReliability (Meta provisional)

Probability & combo summary

  • Opening a starter: P(≥1) ≈ — · key two-card combo ≈ 0.78 · full-brick estimate ≈ 0.02 (all Inferred)
  • Combo output: best PowerIndex 82, median 61, board-per-starter 2.6
  • Turn order: 0 going-first lines vs 0 going-second lines

Strengths

  • Very high combo ceiling with Diabellstar/Chaos Angel big OTK potential
  • Strong disruption suite (12 negation, 10 removal, 9 hand traps)
  • Excellent start probability (99.85% for at least one core piece in opening hand)
  • Solid endboard interaction and spell/trap recursion

Weaknesses

  • Brick-prone due to 8 three-copy cards and 3 one-copy key pieces
  • Light resource economy; limited sustain beyond initial setup
  • Weak side deck options (no side deck present)
  • Inconsistent archetype purity (~26% exact-name cards) can scatter draws

Critical choke points

  • Missing 8 core White Forest/Snake-Eyes cards reduces floor consistency
  • Limited draw/sustain outside initial combo setup
  • No post-side adaptation plan
  • Hand trap reliance without dedicated floodgate control
Priority Remove Add Reason
1 Consider reducing 3-of key pieces (e.g., Witch) to 2 and adding 2 more hand traps or counters Cuts brick variance while preserving combo integrity
2 Add 1-2 generic floodgates or counter traps (e.g., Cosmic Cyclone, Nibiru, Prima Guitarna) if format permits Improves disruption consistency and mirror matchups
3 Build a small side deck (5-10 cards) for meta adaptation Current side deck absence is a major adaptability gap

Evidence & confidence

  • Verified: Card text roles and banlist status from evidence.json; Deck composition and legality checks
  • Observed: Combo best-line data from combos_evidence (none parsed); Usage statistics for core card inclusion rates
  • Inferred: Brick estimates and hand-trap coverage from composition; Combo floor/median from missing boards and card counts; Going-first/second power from hand quality and disruption counts
  • Provisional: Meta power and matchup data (no dated metagame sample); Tournament reliability without match records
  • Data gaps: No combos parsed — combo floor/median/ceiling inferred from text and composition No tournament link — archetype meta-share and per-pilot match record absent No win-rate telemetry in YGOVN (going-first/second, matchup, brick/starter/OTK rates) — inferred Meta Power is Provisional without a dated metagame sample
