Legality

Main 40 / Extra 15 / Side 0 — status under the rules at evaluation time: Illegal. 3 violation(s).

Identity & game plan

  • Win condition: Extra Deck link and synchro finishers (Garunix Eternity, Snake-Eyes Flamberge Dragon, Worldsea Dragon Zealantis, Promethean Princess) after a searcher-driven starter.; Diabellstar the Black Witch 2500 ATK and Fire King High Avatar Garunix 2700 ATK as board pressure.
  • Turn 1 (going first): Search with Fossil Dig, Courtier Ulcanix, Snake-Eye Ash or Poplar, then convert into a Link or Synchro finisher while holding Ash Blossom and Droll for interaction.
  • Turn 2 (going second): Hold Ash Blossom, Droll & Lock Bird and the Fire King negations for the opponent's first Summon or search, then rebuild through the GY revival lines.
  • Recovery: Recycle Snake-Eye and Fire King monsters from the GY with Snake-Eye Oak, Poplar, and Garunix revival effects; Fossil Dig and the Sky Burn banish cost help rebuild.
  • After siding: No side deck is registered, so there is no post-side plan; sideboarding would be needed to answer the listed hand traps or Extra-Deck matchup problems.

Why it scores here

The deck's engine is spread across at least four sub-archetypes (Fire King, Snake-Eye, Jurrac, Charmer) plus generic staples, so only 5.5% of its cards share the Diabellstar name and no single line is reliably live on turn 1 or 2. Its strength is redundancy: about 18 searcher-text cards and four hand traps give a high chance of a functional hand and some route redundancy after disruption. Its finishers (Garunix Eternity, Snake-Eyes Flamberge Dragon, Worldsea Zealantis) give real closing power, but no recorded boards exist, so combo ceiling and median output are text-only inference. The list is illegal (three copies over the limit, including one Forbidden card), so it gets a capped theoretical score, and it carries no side deck, which lowers its adaptability. Archetype popularity was not used to earn points, and no card scores were averaged into the deck score.

Dimension scores

# Dimension Score Evidence
D1 Engine Accessibility & Consistency 38 Diabellstar P(≥1 in opening 5) ≈ 0.34 for a 3-copy card; the core is split across four sub-archetypes, so no single engine is reliably live (Inferred)
D2 Opening-Hand Quality & Brick Management 45 18 searcher-text cards give P(≥1 searcher in hand 5) ≈ 0.96, but Fire King Island, Fire King Sanctuary, Divine Temple and Fossil Dig need specific board states or types to function (Inferred)
D3 Combo Conversion & Ceiling 48 combos_evidence has no parseable boards; conversion ceiling is read from card text only (Inferred)
D4 Combo Floor & Median Output 40 No recorded board data, so median output is unmeasured; the multi-archetype list gives no shared line to anchor a median (Inferred)
D5 Interruption Resilience & Route Redundancy 52 Four hand traps, Snake-Eye and Fire King GY recursion, and two Garunix revival routes give some redundancy across sub-archetypes (Inferred)
D6 Resource Economy, Recovery & Grind 55 Fossil Dig, Snake-Eye Ash/Oak/Poplar and Garunix recursion recycle resources; net card advantage is unmeasured (Inferred)
D7 End-Board & Interaction Quality 60 Two legal Ash Blossom copies, Droll & Lock Bird, Fire King Avatar Arvata and Rangbali negations, and Fire King Sky Burn give dense interaction (Inferred semantic read)
D8 Going-Second & Board-Breaking Power 50 P(≥1 hand trap in going-second hand 6) ≈ 0.49; no going-second split data; Garunix and Flamberge at 2700–3000 ATK give board-breaking reach (Inferred)
D9 Offensive Pressure & Closing Power 62 Extra Deck finishers at 3000 (Garunix Eternity, Flamberge Dragon), 2700 (Promethean Princess, High Avatar Garunix) and 2500 (Zealantis) give strong closing power (Verified stat / Inferred)
D10 Main Deck Efficiency & Flexibility 42 40 Main cards across 26 distinct names, 5.5% exact-archetype purity, and 12 zero-level spells dilute cohesion (Verified composition / Inferred)
D11 Extra Deck Efficiency & Coverage 55 15 Extra cards: 10 Link, 4 Synchro, 1 Xyz across Jurrac, Knightmare, Charmer, Salamangreat and Eyes Restrict; several Extra slots serve off-plan lines (Inferred)
D12 Side Deck Adaptability 10 Zero side-deck cards, so no post-side plan exists in the list (Verified composition / Inferred)
D13 Matchup Coverage & Format Fit 45 No tournament link and no dated meta sample; Diabellstar meta share is unavailable (Provisional)
D14 Pilotability & Error Tolerance 40 Four engines with many conditional Quick Effects and multi-step Summon sequencing raise decision load (Inferred)

How the score was computed

Strategy profile: Toolbox primary, Midrange secondary (structural weights from Toolbox profile; no blend applied). Structural ≈ 47, Going First ≈ 42, Going Second ≈ 46, Meta = provisional, Tournament Reliability ≈ 38. Modifiers: banlist_exposure (-8); engine_conflict (-4). Final formula: No reliable metagame, so Meta is provisional: 0.80*Structural(47) + 0.20*TournamentReliability(38) = 45.2; modifiers -12 gives 33.2; Illegal status caps the final at 30 (theoretical / structural-only)

Probability & combo summary

  • Opening a starter: P(≥1) ≈ 0.34 · 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

  • Dense searcher text (18 cards) makes a functional opening hand likely
  • Four hand traps and multiple negation effects give early interaction
  • High-ATK Extra Deck finishers provide closing power

Weaknesses

  • Illegal list: three copies over the limit, including one Forbidden card
  • Engine split across four sub-archetypes with 5.5% exact-name purity
  • No side deck, so no post-side adaptability
  • No recorded boards, so the combo ceiling and median cannot be measured

Critical choke points

  • Diabellstar 3-copy starter access (P ≈ 0.34 in hand 5)
  • Snake-Eye revival lines depend on Snake-Eye Ash and Oak being live
  • Fire King Island and Sanctuary need specific FIRE monsters on field or in hand
Priority Remove Add Reason
1 Original Sinful Spoils - Snake-Eye (Forbidden) Nothing; remove the Forbidden card to make the list legal A Forbidden card makes the list illegal and blocks any normal Final score
2 One Ash Blossom & Joyous Spring (3 to 2) A non-limited card or a side-slot copy Semi-Limited copy limit is 2
3 One WANTED: Seeker of Sinful Spoils (2 to 1) A legal non-limited card Limited copy limit is 1
4 Off-archetype staples such as Fossil Dig or Divine Temple Side-deck cards (up to 15) for a post-side plan The list has zero side cards and weak archetype cohesion

Evidence & confidence

  • Verified: Legality: three over-limit copies and one Forbidden card (banlist tokens); Main 40 / Extra 15 / Side 0, legal sizes for OCG; Card text and stats for all 40 Main and 15 Extra cards; Archetype spread and purity (5.5%) from composition
  • Inferred: Opening-hand starter and searcher probabilities (hypergeometric); Interaction density and resilience from card text; Consistency and brick estimates; Pilotability from sequencing complexity
  • Provisional: Meta and format fit (no dated metagame sample; no tournament link)
  • 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 for going-first/second, matchup or brick rates Meta Power is provisional unless a dated metagame sample is supplied Deck title is null
