Legality

Main 55 / Extra 15 / Side 0 — status: Illegal. 1 violation(s).

Identity & game plan

  • Win condition: No coherent win condition; Kaiju core (Gadarla, Gameciel, Interrupted Kaiju Slumber) is 9 of 70 cards and is supported by several unrelated engines (Destiny HERO, Horus, Galaxy-Eyes, Cipher, Utopia, Magician, True Draco).; Extra-Deck beatsticks (Galaxy-Eyes Cipher X Dragon, Number 100, Dark Magician of Destruction) that can be summoned without a consistent engine.
  • Turn 1 (going first): Open on Kaiju or Destiny HERO starters, use Fusion Destiny / Metamorphosis / Gadarla pressure; hand traps protect the first summon (Inferred, low reliability).
  • Turn 2 (going second): Use Ash Blossom, Solemn Warning/Judgment, Infinite Impermanence and Droll to answer the opponent's board, then rebuild with Horus revival or Kaiju (Inferred).
  • Recovery: Trade-In and Imsety/Duamutef/Hapi/Qebehsenuef revival from the GY, plus Interrupted Kaiju Slumber banish-to-summon (Inferred; no combo data to verify).
  • After siding: Not applicable: the deck has no Side Deck (side_count 0).

Why it scores here

The deck is Illegal in OCG because it runs one copy of Red-Eyes Dark Dragoon, which is Forbidden, so it gets only a structural score capped at 25 and no normal contextual score. Scoring uses the system, not card averages: the 55-card main splits across roughly seven archetype families (exact-name purity 12.9%, 61 off-archetype copies), so the engines compete for the same hand and Extra Deck slots. Interaction is the strongest part (7 hand traps, 15 negation-text cards, Solemn and Ash Blossom at legal limits), and the Kaiju core is present but thin at 9 copies. There is no combo evidence (total_combos 0), no tournament link, and no Side Deck, so floor, median and ceiling are text-only inference and Meta Power is null. Popularity and archetype usage did not earn points: the only usage core card (Harpie's Feather Duster, 63.6%) is absent from the list.

Dimension scores

# Dimension Score Evidence
D1 Engine Accessibility & Consistency 40 Searcher text in 9 copies gives P(at least one in 5-card hand) about 0.61; the Kaiju starter has 3 copies at P about 0.25 each, so the engine is inconsistent across several archetypes (Inferred)
D2 Opening-Hand Quality & Brick Management 45 Hand quality is mixed: Fusion Destiny, Metamorphosis and Trade-In need specific targets, and several Horus and Destiny HERO monsters only work with King's Sarcophagus or Destiny HERO support (Inferred)
D3 Combo Conversion & Ceiling 35 No parseable boards exist (total_combos 0), so the ceiling rests only on card text such as Fusion Destiny into Destroyer Phoenix and Destiny End Dragoon (Inferred, text-only)
D4 Combo Floor & Median Output 30 No recorded boards, so median output is unmeasured; the floor is likely low because the engines conflict and need several off-archetype pieces (Inferred)
D5 Interruption Resilience & Route Redundancy 40 Revival lines from the GY (Horus, Kaiju) and Trade-In give some recovery after one interruption, but there is no independent second route confirmed in text (Inferred)
D6 Resource Economy, Recovery & Grind 45 Trade-In, Imsety and the Horus revival loop recycle resources through the GY; the card cost to set up is high across 27 distinct main-deck cards (Inferred)
D7 End-Board & Interaction Quality 55 Seven hand traps, 15 negation-text cards, Solemn Judgment and Solemn Warning at 1-2 copies each, plus Ash Blossom at 2 copies give broad layered interaction (Inferred semantic read)
D8 Going-Second & Board-Breaking Power 50 Lightning Storm, Gameciel and Imsety-style effects can clear or contest a board; the Going-Second split is unmeasured so this stays text-based (Inferred)
D9 Offensive Pressure & Closing Power 50 Closing power comes from Galaxy-Eyes Cipher X Dragon (4000 ATK), Destiny End Dragoon and Dogma/Destro-Dogma (3400 ATK), but access is unreliable (Inferred)
D10 Main Deck Efficiency & Flexibility 40 55 main cards spanning 27 distinct names with 12 singletons and 13 triples; compactness is moderate and the deck mixes several archetypes instead of one engine (Verified structure, Inferred consequence)
D11 Extra Deck Efficiency & Coverage 45 Extra Deck has 15 cards across Fusion, Xyz and Link-less Xyz/Fusion lines with several non-synergistic routes (Galaxy-Eyes, Number, Destiny HERO, Dark Magician of Destruction) (Verified structure, Inferred use)
D12 Side Deck Adaptability 10 No Side Deck is supplied (side_count 0), so post-side adaptability is effectively absent (Verified)
D13 Matchup Coverage & Format Fit 40 No tournament_context and no dated meta sample; archetype share is unknown, so this is Provisional
D14 Pilotability & Error Tolerance 40 Several multi-step lines (Destiny HERO Fusion chains, Horus revival with King's Sarcophagus, Number Xyz material transfers) raise decision load (Inferred)

How the score was computed

Strategy profile: Toolbox. Structural ≈ 41, Going First ≈ 40, Going Second ≈ 42, Meta = provisional, Tournament Reliability ≈ 35. Modifiers: banlist_exposure (-4); engine_conflicts (-3). Final formula: Structural 41 (Toolbox weights); unnormalised blend 0.80*41 + 0.20*35 = 39.8; Illegal cap applied (theoretical/structural-only) -> final 25; Meta provisional/null

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

  • Layered interaction: 7 hand traps, Solemn Judgment, Solemn Warning, Ash Blossom and Droll & Lock Bird
  • Searcher density (9 copies) gives reasonable access to the engine pieces
  • Strong Extra Deck closers if the engine connects

Weaknesses

  • Illegal in OCG: Red-Eyes Dark Dragoon is Forbidden and over the copy limit
  • Archetype fragmentation: exact Kaiju purity 12.9% with 61 off-archetype copies
  • No Side Deck (side_count 0)
  • Kaiju core (9 copies) is thin for the Kaiju name

Critical choke points

  • Forbidden Red-Eyes Dark Dragoon: must be removed before the deck can be legal
  • Kaiju summon conditions (only one Kaiju may be controlled) with only 9 engine copies
Priority Remove Add Reason
1 Red-Eyes Dark Dragoon Any legal Extra Deck Fusion or Xyz monster that fits the chosen engine The deck is illegal in OCG as built; removing the Forbidden card is required before any normal score applies
2 Off-archetype Extra Deck slots (Number F0 Utopia pieces, Galaxy-Eyes Cipher X, Dark Magician of Destruction) Additional Kaiju or single-engine cards Consolidating on one engine would raise the Kaiju core and reduce Extra Deck fragmentation

Evidence & confidence

  • Verified: Illegal status: Red-Eyes Dark Dragoon, Forbidden, 1 copy run, 0 legal; Main 55 and Extra 15 are within OCG size limits; Side 0; Copy-limit checks for the other Limited and Semi-Limited cards pass (1 or 2 copies each); Exact Kaiju purity 12.9% and 61 off-archetype copies
  • Observed: No combos were recorded for this deck (total_combos 0)
  • Inferred: Hypergeometric draw estimates (0.25 for a 3-copy card, 0.61 for searcher group); Engine conflicts and fragmentation read from card text; Interaction quality from text and role tags
  • Provisional: Meta and tournament reliability (no dated meta 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 match record absent no win-rate telemetry for going-first/second, matchup, or brick/starter rates Meta Power is Provisional unless a dated metagame sample is supplied no Side Deck supplied
