Legality

Main 57 / Extra 15 / Side 0 — status under the rules at evaluation time: Illegal. 5 violation(s).

Identity & game plan

  • Win condition: Extra Deck boss monsters (K9-X Werewolf, Elfnote June Pride, Dark Magician of Destruction, Gallant Bandit line) built on a Spellbook/Charmer/Elfnote engine, with off-archetype hand traps protecting the first turn; Fusion and Link bosses from the Charmer and Spellbook packages, which only matter if the Forbidden extra-deck cards are removed and the list is re-legalised
  • Turn 1 (going first): Open on a searcher (Elfnote Lucina, Spellbook Magician of Prophecy, Elfnote Regina/Fortuna, K9-66a Jokul), set up a Level 5 or Charmer Xyz/Fusion route, and hold Solemn Judgment, Maxx C or Ash Blossom for the opponent's first interaction
  • Turn 2 (going second): Use the hand traps (Ash Blossom, Ghost Ogre, Ghost Belle, Droll and Lock Bird, Maxx C) to answer the opponent's board, then rebuild with searchers; interaction density matters more than the combo line
  • Recovery: Ghost Belle, Ash Blossom and the Spellbook searchers give repeatable card flow after a single-card disruption; recursion through Awakening of the Possessed and Elfnote Welcome Home fills the gap
  • After siding: Not evaluable: Side Deck size is 0, so there is no post-side plan in the list

Why it scores here

The deck is scored as a system, not as an average of its cards, and it is capped because five Forbidden Extra Deck cards (Charmer Quartet in Bloom, Reprodocus, Red-Eyes Dark Dragoon, Crystal Wing Synchro Dragon, Baronne de Fleur) make the list illegal in OCG. Its reliable part is the access layer: 22 searcher-text cards give about a 92% chance of at least one searcher in an opening 5, and the 11 hand traps and Solemn Judgment give strong interaction on the going-second side. Its weak part is coherence: only 5 of 72 archetype copies are exact K9 cards (6.9% exact-name purity), and the rest is a loose mix of Charmer, Spellbook, Elfnote, Possessed and Dark Magician, so the engines do not share a single conversion route. No combo boards exist in the evidence, so conversion and median output are text-only inferences, and popularity or archetype stats did not earn any points. The score is therefore a theoretical structural read only, capped at 25 because the list cannot be played as built.

Dimension scores

# Dimension Score Evidence
D1 Engine Accessibility & Consistency 62 P(at least one searcher in opening 5) = 0.92 across 22 searcher-text cards; starter access is strong, but the starters do not share a route (Inferred)
D2 Opening-Hand Quality & Brick Management 50 40 distinct main-deck cards with 30 singletons and 14 hand traps / techs; brick risk from non-engine hand traps is moderate (Inferred)
D3 Combo Conversion & Ceiling 45 No parseable boards; the Charmer, Spellbook and Elfnote text links suggest a few real routes, but they are not verified (Inferred)
D4 Combo Floor & Median Output 40 No combo evidence supplied, so median output is unknown beyond text; the off-archetype mix lowers expected output (Inferred)
D5 Interruption Resilience & Route Redundancy 58 Ash Blossom x2, Ghost Ogre x2, Ghost Belle x2 and Droll and Lock Bird give several independent answers to a single disruption (Inferred)
D6 Resource Economy, Recovery & Grind 50 Recursion and card flow come from Ghost Belle, Spellbook searchers and Awakening of the Possessed, with no measured economy data (Inferred)
D7 End-Board & Interaction Quality 70 Interaction density is high: 11 hand traps plus Solemn Judgment, Mind Mirror Force, Maxx C and Dimensional Barrier, though 2 Limited copies are counted by ban status (Inferred)
D8 Going-Second & Board-Breaking Power 68 Going-second value comes from hand traps and Solemn Judgment, which answer an established board; no going-second split data exists (Inferred)
D9 Offensive Pressure & Closing Power 55 Extra Deck bosses reach 2300 to 3300 ATK (K9-X Werewolf 3300, Elfnote June Pride 3100, Dark Magician of Destruction 2800); closing power is real but unevidenced in play (Inferred)
D10 Main Deck Efficiency & Flexibility 45 57 main-deck cards with 30 singletons and a low archetype purity; compact enough for the size rule but loosely built (Verified count, Inferred quality)
D11 Extra Deck Efficiency & Coverage 40 15 Extra Deck slots with 5 Forbidden cards; after removing them 10 slots remain, which is an efficient but thin set of bosses (Inferred)
D12 Side Deck Adaptability 15 No side deck (Side Deck size 0); no post-side plan can be evaluated (Provisional)
D13 Matchup Coverage & Format Fit 40 No tournament link and no dated metagame sample; format fit cannot be measured (Provisional)
D14 Pilotability & Error Tolerance 45 Many interaction decisions and a loose engine mix raise the decision count per turn; pilotability is moderate (Inferred)

How the score was computed

Strategy profile: Toolbox primary with Stun as a secondary read; the Stun weight was not applied as a separate blend. Structural ≈ 51, Going First ≈ 46, Going Second ≈ 55, Meta = provisional, Tournament Reliability ≈ 40. Modifiers: Banlist exposure (-10); Engine conflicts (-2). Final formula: 0.80*Structural + 0.20*TournamentReliability + ContextModifiers = 0.80*51 + 0.20*40 - 12 = 28.8, then capped at 25 because the deck is Illegal (Meta Provisional)

Probability & combo summary

  • Opening a starter: P(≥1) ≈ 0.92 · 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

  • Searcher density gives reliable access to a starter (P 0.92 for at least one searcher in a 5-card hand)
  • Eleven hand traps plus Solemn Judgment, Mind Mirror Force and Maxx C give strong interaction on the going-second side
  • Ghost Belle and Ash Blossom give repeatable answers, so the deck can absorb one disruption

Weaknesses

  • Illegal in OCG: five Forbidden Extra Deck cards
  • Very low exact archetype purity (6.9%); the deck is a loose mix of sub-archetypes
  • No side deck, so no post-side adaptation
  • No combo evidence, so conversion and median output cannot be verified

Critical choke points

  • The Extra Deck is the only source of bosses, and two of the five illegal cards are the strongest extra-deck options
  • No side deck means every matchup is played with the same main-deck interaction
Priority Remove Add Reason
1 Charmer Quartet in Bloom, Reprodocus, Red-Eyes Dark Dragoon, Crystal Wing Synchro Dragon, Baronne de Fleur Legal K9 bosses and staples from the usage core, for example K9-ØØ Lupis or K9-17 Ripper if they are legal in OCG; confirm each with the card list before adding Removes the five Forbidden copies that make the deck illegal; without this change no normal score applies
2 A few off-archetype singletons with no engine link A coherent K9 or Charmer core (for example K9-X Werewolf, if it is actually in the list, or more K9 searchers) Raises exact archetype purity and gives the engine one conversion route instead of several
3 None A 15-card side deck with hand traps and anti-Extra Deck answers Gives a post-side plan so the deck can be evaluated for best-of-3 and matchup adaptation

Evidence & confidence

  • Verified: Legality: 5 Forbidden cards over limit; main 57 and extra 15 are within size rules; Card text for all listed cards comes from the evidence excerpts; Searcher-text copies (22) and hand-trap copies (11) from composition
  • Inferred: Starter access probability (0.92) and other hypergeometric estimates; Interaction density, recovery and brick-risk reads from card text; Going-first and going-second read from hand-trap density
  • Provisional: Meta and format fit (D13) and tournament reliability (no dated sample, no tournament link); Post-side plan (no side deck)
  • 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 this deck Meta Power is Provisional: no dated metagame sample No side deck, so no post-side evaluation Data inconsistency: K9-X Werewolf (90303227) appears in the card list with 1 copy, but usage statistics marks it in this deck false and lists it in missing core cards; the list may be stale
