Legality

Main 40 / Extra 15 / Side 0 — status: Legal.

Identity & game plan

  • Win condition: Extra Deck bosses: Umbral Horror C104 (3000 ATK), Lava Golem (3000, Special Summoned by Tributing 2 opponent monsters), K9-66X Jacks (2600) and Vallon (2500) via Xyz; Charmers of the Grand Circle Fusion (x3) and Possessed Destiny - Wynn taking control of opponent monsters
  • Turn 1 (going first): Normal Summon Spellbook Magician of Prophecy to search a Spellbook, or use Spellbook of Secrets / Grand Circle to fetch Charmers and Fusion or Xyz into a 3000-ATK boss (Inferred from card text)
  • Turn 2 (going second): Use Possessed Destiny or Dharc to steal/swap a monster, and Lava Golem if the opponent has 2 monsters to Tribute; then Xyz/Fusion into a boss (Inferred)
  • Recovery: Spellbook of Knowledge draw 2 and Spellbook of Secrets search from the Deck; Possessed/Charmer recursion from GY (Inferred)
  • After siding: None: the deck runs 0 side-deck cards in a best-of-3 format, so no post-side plan exists

Why it scores here

The deck is a multi-theme Spellbook list: its exact-name archetype copies are only 10 of 55 archetype cards, with K9, Charmer, Possessed, Rescue-ACE, Familiar-Possessed, Number and Skyblaster cards filling the rest. The 10 Spellbook starters give roughly a 78% chance of at least one in a 5-card opening hand (about 85% going second; hypergeometric, Inferred), but any single theme's engine is far less reliable, which holds D1 and D2 near the middle. Removal text is dense (13 cards), with Umbral Horror C104, K9-66X Jacks, Vallon and Possessed Destiny - Wynn providing layered answers, and the closing bosses reach 2500-3000 ATK, so D7 and D9 are the strongest dimensions. There are no recorded boards, so combo ceiling and median are text-only inferences, and the deck has no side deck, which caps D12 and the Structural score. Usage stats show only 6 of 24 archetype core cards present, so the list is real and accessible but is not scored as strong for being a popular archetype, and no card scores were averaged.

Dimension scores

# Dimension Score Evidence
D1 Engine Accessibility & Consistency 52 P(>=1 of 10 Spellbook starters in 5-card hand) = 0.78 going first, 0.85 going second; any single sub-engine (e.g. one Charmer) is 0.125 per copy in 5 cards (Inferred)
D2 Opening-Hand Quality & Brick Management 42 17 Spells and several situational cards (Lava Golem needs opponent monsters, Chaotic Elements needs L5 DARK/LIGHT Pyro or Aqua); four theme splits with 18 singletons (Inferred)
D3 Combo Conversion & Ceiling 62 Ceiling from Grand Circle to Charmers Fusion, then Umbral Horror C104 or Jacks Xyz, plausibly reaches a 3000-ATK boss with a negate or destroy; no recorded boards (Inferred from card text)
D4 Combo Floor & Median Output 48 No observed boards, so the median is inferred to be well below the ceiling because the starter-to-line routes depend on multiple sub-archetypes (Inferred)
D5 Interruption Resilience & Route Redundancy 50 Redundant starters across themes (Magician of Prophecy, Rescue-ACE Impulse, K9 Lantern, Lupis) and Knowledge/Secrets recursion; no hand traps (Inferred)
D6 Resource Economy, Recovery & Grind 58 Spellbook of Knowledge draws 2, Secrets searches, Grand Circle adds 4 Charmers: strong card advantage on paper (Inferred from text)
D7 End-Board & Interaction Quality 66 Removal text on 13 cards and one negation (Ichirin); Umbral Horror C104 negates, Possessed Destiny-Wynn steals; no hand traps (Verified text, Inferred quality)
D8 Going-Second & Board-Breaking Power 55 Going-second plays rely on Lava Golem tributing opponent monsters and steal effects; no hand traps or floodgates (Inferred)
D9 Offensive Pressure & Closing Power 68 Closers at 2500-3000 ATK (Lava Golem 3000, Umbral C104 3000, Jacks 2600, Vallon 2500) with destruction and control effects (Verified stats, Inferred pressure)
D10 Main Deck Efficiency & Flexibility 45 26 distinct main cards with 18 singletons and 6 triple-copy cards across at least five themes; compactness is low (Verified composition, Inferred consistency)
D11 Extra Deck Efficiency & Coverage 48 11 Xyz and 4 Fusion, several needing specific Number or K9 materials; broad coverage but low coherence across themes (Verified composition, Inferred)
D12 Side Deck Adaptability 12 Side deck is 0 cards in a best-of-3 format, so there is no post-side plan (Verified)
D13 Matchup Coverage & Format Fit 42 No tournament link; archetype usage only, and no dated metagame sample (Provisional)
D14 Pilotability & Error Tolerance 38 Multiple engines and many decision points across Spellbook, Charmer, K9, Number and Possessed lines (Inferred)

How the score was computed

Strategy profile: Toolbox primary with Midrange secondary (Toolbox weights used directly; secondary not blended). Structural ≈ 51, Going First ≈ 55, Going Second ≈ 53, Meta = provisional, Tournament Reliability ≈ 42. Modifiers: No side deck (-4); Engine conflict across themes (-4); Core gap vs archetype usage (-2); Dense removal and negation text (2). Final formula: 0.80*Structural + 0.20*TournamentReliability + ContextModifiers (Meta provisional): 0.80*51 + 0.20*42 - 8 = 41

Probability & combo summary

  • Opening a starter: P(≥1) ≈ 0.78 · key two-card combo ≈ — · full-brick estimate ≈ 0.22 (all Inferred)
  • Combo output: best PowerIndex —, median —, board-per-starter —
  • Turn order: 0 going-first lines vs 0 going-second lines

Strengths

  • Dense removal and negation text across 13 cards
  • Multiple 2500-3000 ATK closers across Xyz and Fusion
  • Strong draw and search text (Knowledge, Secrets, Grand Circle)
  • Redundant Level 5 starters across several themes

Weaknesses

  • Only 10 of 55 archetype cards are exact Spellbook; theme split is severe
  • No hand traps, floodgates or tech cards
  • No side deck in a best-of-3 format
  • Low archetype core presence (6 of 24 usage-core cards)
  • Multiple singletons (18) reduce consistency

Critical choke points

  • Spellbook starters (10 cards) as the only reliable opener
  • Level 5 monsters needed for both K9 and Charmer Xyz/Fusion routes
  • Lava Golem requires opponent monsters to be live
Priority Remove Add Reason
1 0 side deck A 15-card side deck with targeted hand traps or removal for the opponent's main threats Best-of-3 play has no post-side plan (D12 = 12), the largest single gap
2 Spiritual Water Art - Aoi (1) A second Spellbook or Charmer starter from the usage-core list (e.g. Droll & Lock Bird if legal in OCG) Raises consistency of the main engine and reduces off-theme dead draws
3 Lava Golem (3) A card that works without opponent monsters, such as a second Spellbook starter Lava Golem is dead when the opponent has no monsters, which the going-first hand often faces

Evidence & confidence

  • Verified: Main deck 40, Extra 15, side 0 (OCG size rules 40-60 / 0-15); K9-66a Jokul and A Case for K9 are Limited at 1 copy each, run at the legal limit; 0 hand traps, 0 floodgates, 13 removal text, 1 negation text; Exact archetype purity 10 of 55 archetype cards (18.2%); Usage-core presence 6 of 24 (25%)
  • Inferred: Opening-hand starter probabilities 0.78 (first) and 0.85 (second); Combo ceiling and median from card text (no recorded boards); Going-first and going-second plans from card text; Brick and consistency estimates
  • Provisional: Meta power and matchup fit (no dated metagame sample); Tournament reliability (no tournament link)
  • Data gaps: no combos supplied: ceiling and median are text-only inference no tournament link: meta-share and per-pilot record absent no win-rate or matchup telemetry in YGOVN Meta Power is Provisional without a dated metagame sample no side deck: post-side performance cannot be assessed
