Identity & game plan

  • Win condition: Diabellstar the Black Witch and Snake-Eyes Flamberge Dragon boards, closed by Link monsters such as Worldsea Dragon Zealantis and Promethean Princess; Azamina Mu Rcielago field pressure from Sinful Spoils recursion (Forbidden Azamina Ilia Silvia removed in any legal build)
  • Turn 1 (going first): Open a Snake-Eye or Mulcharmy starter, search Snake-Eye Ash or Snake-Eyes Poplar, and extend into a Link Summon while hand traps are held for the opponent's first starter
  • Turn 2 (going second): Use Ash Blossom, Effect Veiler, Infinite Impermanence and Nibiru style hand traps to break the opponent's first Special Summon, then recover through Mulcharmy draw effects
  • Recovery: Mulcharmy Fuwalos and Mulcharmy Purulia draw cards when the field is empty; Sinful Spoils searchers rebuild the hand from Deck and GY
  • After siding: No side deck is registered, so no post-side plan can be verified

Why it scores here

The list is Illegal in OCG: three Forbidden cards (Called by the Grave, Triple Tactics Talent, Azamina Ilia Silvia) and four over-limit Limited or Semi-Limited cards (WANTED, Snake-Eye Ash, Ash Blossom, Dominus Impulse), so under the rubric it receives only a theoretical structural read capped at 35. The structural read finds an archetype core that is reasonably accessible on the draw (P(at least one core-group card in the opening 5) ≈ 0.72, Inferred), with 14 hand traps and 20 tech or interaction cards supplying real going-second disruption. The deck's coherence is weak: exact-name Diabellstar purity is only 4.3% and the main deck spreads across roughly 19 sub-archetypes, so the engines conflict and bricks are likely. No side deck, no combo records and no tournament or meta data exist, so going-second adaptation and matchup fit are scored provisionally. Popularity and card quality were not averaged into the score.

Dimension scores

# Dimension Score Evidence
D1 Engine Accessibility & Consistency 60 P(≥1 core-group card in opening 5) ≈ 0.72 across the archetype core; Snake-Eye and Diabellstar starters are split across sub-archetypes (Inferred)
D2 Opening-Hand Quality & Brick Management 45 14 hand traps and 20 tech cards in 55 main slots raise brick and dead-card risk; sub-archetype spread is 19 names (Inferred)
D3 Combo Conversion & Ceiling 50 No parseable combo boards; ceiling read relies on Link and Fusion text only (Inferred)
D4 Combo Floor & Median Output 45 No recorded boards, so median output cannot be measured; text-only read (Inferred)
D5 Interruption Resilience & Route Redundancy 55 Multiple independent starters (Snake-Eye, Mulcharmy, Sinful Spoils) and redundant hand traps give some route redundancy (Inferred)
D6 Resource Economy, Recovery & Grind 50 Mulcharmy draw and Sinful Spoils recursion provide recovery, but the deck spends many cards on interaction (Inferred)
D7 End-Board & Interaction Quality 60 14 hand traps and 15 negation-text cards give broad interaction on paper, but three of them are Forbidden or over the limit (Verified legality, Inferred quality)
D8 Going-Second & Board-Breaking Power 50 Going-second value rests on hand traps and Snake-Eyes Flamberge Dragon board-breaking text; no split data exists (Inferred)
D9 Offensive Pressure & Closing Power 45 Link monsters and Snake-Eyes Diabellstar provide 2500 to 3000 ATK boards, but the closing route is not verified (Inferred)
D10 Main Deck Efficiency & Flexibility 40 55 main cards against a 40 to 60 legal range, 31 distinct main cards and 4.3% exact-name purity point to a diffuse, low-efficiency list (Verified counts, Inferred efficiency)
D11 Extra Deck Efficiency & Coverage 55 13 Link and 2 Fusion Extra cards with a 15-card cap; the Extra deck is full and Forbidden Azamina Ilia Silvia must be removed (Verified)
D12 Side Deck Adaptability 25 Side deck is empty, so there is no post-side plan (Verified)
D13 Matchup Coverage & Format Fit 35 No tournament link or dated meta sample; archetype usage stats available but not a matchup read (Provisional)
D14 Pilotability & Error Tolerance 40 Multi-step Link and Sinful Spoils sequences with many restricted choices raise the error rate (Inferred)

How the score was computed

Strategy profile: Toolbox. Structural ≈ 49, Going First ≈ 45, Going Second ≈ 50, Meta = provisional, Tournament Reliability ≈ 35. Modifiers: Illegal list cap (-11). Final formula: 0.80*Structural + 0.20*TournamentReliability (Meta provisional) + illegal-list cap modifier (-11); theoretical only

Probability & combo summary

  • Opening a starter: P(≥1) ≈ 0.25 · 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

  • Large hand-trap suite (14) gives going-second disruption on paper
  • Multiple independent starters across Snake-Eye, Mulcharmy and Sinful Spoils
  • Link and Fusion Extra Deck gives access to several 2500+ ATK boards

Weaknesses

  • Illegal in OCG: three Forbidden and four over-limit cards
  • Low exact-name purity (4.3%) and 19 sub-archetype names fragment the engine
  • No side deck, so no post-side adaptation
  • Heavy tech and hand-trap density risks dead cards in openings

Critical choke points

  • Opening-hand starter density (Snake-Eye Ash and Poplar copies, once limits are enforced)
  • Sinful Spoils searchers, which depend on WANTED copies that are over the limit
Priority Remove Add Reason
1 Called by the Grave, Triple Tactics Talent, Azamina Ilia Silvia Legal substitutes from the same archetype core or a second Snake-Eye starter Forbidden cards make the list illegal; this is the first fix before any other evaluation applies
2 1 WANTED: Seeker of Sinful Spoils, 1 Snake-Eye Ash, 1 Ash Blossom & Joyous Spring, 1 Dominus Impulse Legal copy-limit alternatives or a 1-copy tech Brings each card within its Limited or Semi-Limited copy count
3 Low-impact tech cards (Dimensional Barrier, Anti-Spell Fragrance) A Side Deck of 10 to 15 cards for best-of-3 play A side deck adds post-side adaptability, which the current list lacks entirely

Evidence & confidence

  • Verified: Forbidden status of Called by the Grave, Triple Tactics Talent and Azamina Ilia Silvia; Copy-limit violations for WANTED, Snake-Eye Ash, Ash Blossom and Dominus Impulse; Main 55, Extra 15, Side 0 counts; 31 distinct main cards
  • Inferred: P(≥1 core-group card in opening 5) ≈ 0.72; Brick risk from hand-trap and tech density; Interaction quality from negation and removal text; Engine conflict across sub-archetypes
  • Provisional: Meta power (no dated metagame sample); Matchup fit and tournament reliability
  • Data gaps: No combos supplied; combo floor, median and ceiling are text-only inference No tournament link; archetype meta-share and per-pilot record absent No win-rate telemetry; going-first and going-second splits are Inferred No side deck registered; post-side plan cannot be verified Meta Power is Provisional unless a dated metagame sample is supplied
