Identity & game plan

  • Win condition: Xyz boss monsters (K9-66X Jacks, K9-00 Hound, Umbral Horror Masquerade, Vallon) built from K9 level-5 monsters, with Charmer and Spellbook searchers feeding the line; Fusion boss Charmers of the Grand Circle and Possessed Destiny - Wynn, plus Number-based Xyz for board control
  • Turn 1 (going first): Search a Spellbook or Charmer enabler, Normal Summon K9-66b Lantern or K9-00 Lupis, then extend into a level-5 Xyz or Fusion Summon to clear a single threat
  • Turn 2 (going second): Hand-based searches and removal (Pair Bear Scare, Forced Release, Possessed Destiny) to answer the opening board, then Xyz into a boss from the Extra Deck
  • Recovery: Recycle Charmers and Lantern from the GY through Spellbook of Secrets and Knowledge, and Xyz detach effects to rebuild a board
  • After siding: No side deck is registered, so no post-side plan can be evaluated

Why it scores here

The deck reliably opens a functional hand because 23 main-deck cards carry searcher text and the probability of at least one searcher in an opening five is about 0.99, so the engine is accessible even though the exact K9 core is thin (9 exact-name copies, 16.4% exact purity). Its conversion relies on Xyz and Fusion bosses drawn from the Extra Deck, with Jacks, Hound, Umbral Horror Masquerade and Vallon providing high ATK and removal text, but no recorded boards exist, so ceiling and median are inferred from card text rather than measured. Interaction is moderate (13 removal-text cards, one negation, zero hand traps and zero floodgates), and recursion through Charmers and Lantern supports resilience after one disruption. Popularity or archetype usage did not earn points, and the score was not produced by averaging individual card scores; the spread across Spellbook, Charmer, Possessed and Rescue-ACE sub-engines lowers coherence, and the missing side deck caps the post-side score.

Dimension scores

# Dimension Score Evidence
D1 Engine Accessibility & Consistency 62 P(≥1 searcher in 5-card opening) ≈ 0.99 across 23 searcher-text cards; exact K9 starter access is weaker (Lantern 2 copies ≈ 0.24 per hand) (Inferred)
D2 Opening-Hand Quality & Brick Management 58 Searchers and draw text cover most hands, but 17 spells and a 14-card generic spread add redundancy and possible dead-card hands (Inferred)
D3 Combo Conversion & Ceiling 55 No recorded boards; ceiling is read from text as Xyz/Fusion boss lines on a one-card-starter base (Inferred)
D4 Combo Floor & Median Output 45 combos_evidence is empty, so median output is an inference from searcher density and sub-engine overlap, not measured (Inferred)
D5 Interruption Resilience & Route Redundancy 60 Recursion from Charmers, Lantern and Ripper plus several independent starters give a second route after one disruption (Inferred)
D6 Resource Economy, Recovery & Grind 66 Draw and search text (Spellbook of Knowledge, Ripper, Charmers) and GY recycling via Spellbook of Secrets support rebuilding (Inferred)
D7 End-Board & Interaction Quality 60 13 removal-text cards and 1 negation (Masquerade, Ripper, Umbral Horror) without hand traps or floodgates; layering is moderate (Verified count, Inferred quality)
D8 Going-Second & Board-Breaking Power 55 Going-second value rests on removal spells and Jacks/Umbral Horror reaching the board; no going-second split is recorded (Inferred)
D9 Offensive Pressure & Closing Power 62 Boss ATK values of 2500 to 3000 (Umbral Horror 3000, Jacks 2600, Masquerade 2700) give closing power (Verified stats)
D10 Main Deck Efficiency & Flexibility 45 Exact-name purity is 16.4% with 46 off-archetype copies across 11 sub-archetypes; coherence is low but the 40-card size is legal (Verified)
D11 Extra Deck Efficiency & Coverage 58 11 Xyz and 4 Fusion in the Extra Deck, several of them mandatory for K9 lines, cover varied boards; Charmer fusions need specific materials (Verified composition, Inferred flexibility)
D12 Side Deck Adaptability 15 No side deck is registered, so there is no post-side coherence to assess (Verified absence)
D13 Matchup Coverage & Format Fit 50 No tournament link and no archetype meta-share in the evidence, so format fit is provisional (Provisional)
D14 Pilotability & Error Tolerance 45 Multiple Xyz and Fusion steps with search chains and several decision points per turn make the deck demanding to pilot (Inferred)

How the score was computed

Strategy profile: Midrange primary, no secondary weighting applied. Structural ≈ 55, Going First ≈ 52, Going Second ≈ 50, Meta = provisional, Tournament Reliability ≈ 52. Modifiers: banlist_exposure (-2); engine_conflicts (-3). Final formula: 0.80*Structural + 0.20*TournamentReliability + ContextModifiers (Meta provisional, no dated sample); 0.80*55.2 + 0.20*52 - 5 = 49.6 → 50

Probability & combo summary

  • Opening a starter: P(≥1) ≈ 0.99 · 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 near-certain access to some enabler every opening hand
  • Several high-ATK Xyz and Fusion bosses with removal or negation text
  • Recursion through Charmers, Lantern and Spellbook cards supports grind

Weaknesses

  • Exact K9 core is thin (9 copies) and the archetype core is only 33% present against the usage baseline
  • Low exact archetype purity fragments the engine across sub-archetypes
  • No side deck, so no post-side adaptation

Critical choke points

  • K9 level-5 monsters (Lantern, Lupis, Jokul) are needed to build the main Xyz line; losing them to a single removal forces a slow rebuild
  • Two Limited cards each run as single copies
Priority Remove Add Reason
1 One off-archetype spell with no synergy (generic spread) Additional K9 monster or K9 Quick-Play spell to raise exact purity Raises engine coherence and starter density without changing the Xyz plan (Inferred)
2 Non-engine Possessed card Core K9 searcher or disruption card Reduces sub-engine conflict and improves D10 coherence (Inferred)

Evidence & confidence

  • Verified: Main 40, Extra 15, Side 0; legal under OCG ban list; Two Limited cards each at one legal copy; Archetype purity 16.4% and 23 searcher-text cards from the export
  • Inferred: Opening-hand consistency for the K9 starters and the searcher-based access estimate; Interaction quality, resilience and going-second board-breaking scores; Pilotability estimate from Xyz and Fusion chain length
  • Provisional: Format fit and meta share, because no tournament link or dated meta sample exists
  • Data gaps: no combos supplied — combo floor/median/ceiling is text-only inference no tournament link — archetype meta-share and per-pilot match record absent no win-rate telemetry exists in YGOVN (going-first/second, matchup, game-level, brick/starter/OTK rates) — those signals are Inferred or Unknown Meta Power is Provisional unless a dated metagame sample is supplied No side deck registered, so post-side adaptability is unmeasured
