Spellbook Deck #672201 — Yu-Gi-Oh! OCG

Deck — Deck Power Evaluation

Final Contextual Deck Power: 35/100 (±8 · Confidence: Low)

• Primary strategy: Midrange
• Secondary strategies: Toolbox
• Format: ocg

Legality

Main 57 / Extra 15 / Side 0 — status under the rules at evaluation time: Illegal. 3 violation(s).

Identity & game plan

• Win condition: Extra Deck beatdown through Link/Fusion boards (Zoroa the Magistus Verethragna, Underworld Goddess, Knightmare Unicorn, Super Starslayer TY-PHON) after the deck fills the board via Charmer/Magistus/Mulcharmy summons.; Hand-trap and negate attrition (Ash Blossom, Ghost Belle, Droll, Nibiru, Gorgon, Angel Statue) that trades out the opponent's interaction and lets a single threat stick.
• Turn 1 (going first): Search with Spellbook Magician of Prophecy and Spirit Charmers toward a Charmer/Possessed line, then Link or Fusion into a boss; the list has no single reliable T1 starter.
• Turn 2 (going second): Hold Ash Blossom, Ghost Belle and Droll to stop the opponent's first summon, then rebuild a board with Mulcharmy draws and Charmer flips.
• Recovery: Spellbook recursion (Spellbook of Fate from GY, Spellbook of the Grand Circle banish-to-Fusion) and Mulcharmy card draw restore hand size after a disrupted turn.
• After siding: No Side Deck is registered (0 cards), so there is no post-side plan; the evaluation cannot credit one.

Why it scores here

The deck reliably opens a searcher line: about 86% of opening 5-card hands contain at least one searcher-text card (Inferred), so the engine is usually switched on. Conversion is the weak link, because the list mixes Spellbook, Charmer, Magistus, Mulcharmy, Endymion and Forbidden cards (exact Spellbook name purity 13.9%), and the evidence contains no recorded boards, so the ceiling and median are text-based reads only. Interaction is the strongest part of the system: nine hand traps, Gorgon, Angel Statue, Skill Drain and Lightning Storm give layered negates, and the 66% chance of a hand trap in a going-second 6-card hand supports the second-player plan. Closing power comes from several 2200-3000 ATK Link and Fusion bosses, but the deck has no side deck and is Illegal as built (Called by the Grave is Forbidden; Ash Blossom and Droll exceed their limits), so its score is capped. The score comes from consistency, interaction and boss power on the system, not from Spellbook's popularity or from averaging the individual card scores.

Dimension scores

How the score was computed

Strategy profile: Midrange. Structural ≈ 50, Going First ≈ 46, Going Second ≈ 54, Meta = provisional, Tournament Reliability ≈ 42. Modifiers: banlist exposure (-8); engine conflicts (-4). Final formula: No reliable metagame: 0.80*Structural(49.7) + 0.20*TournamentReliability(42) + ContextModifiers(-12) = 36.2, capped at 35 because the list is Illegal. Meta Power provisional (null). Midrange profile, Toolbox secondary not blended.

Probability & combo summary

• Opening a starter: P(≥1) ≈ 0.86 · 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 negates and hand traps (9 hand traps, Gorgon, Angel Statue, Skill Drain) cover the opponent's first and second summons
• Searcher text is widely present (18 cards), so the engine is usually live
• High-ATK Link and Fusion bosses give closing power

Weaknesses

• Illegal as built: Called by the Grave is Forbidden and two cards exceed copy limits
• No Side Deck, so no post-side adaptation
• Engine conflicts among several archetypes lower consistency and pilotability
• No recorded boards, so the combo ceiling and floor are unverified

Critical choke points

• Spellbook Magician of Prophecy and Spellbook of Secrets as the searcher line
• Single-copy Extra-Deck bosses that depend on a Link or Fusion material route
• Hand-trap density as the only protection on the going-second turn

Recommended changes

Evidence & confidence

• Verified: Legality: Illegal, Called by the Grave Forbidden with 1 copy run, Ash Blossom 3 copies vs 2 legal, Droll 2 copies vs 1 legal; Main 57, Extra 15, Side 0 are within the OCG size rules; Card text and stats for all listed cards; Archetype core usage stats (9 of 19 core cards present)
• Inferred: Consistency estimates from the hypergeometric draw table; Going-first and going-second power splits; Interaction and pilotability reads from card text
• Provisional: Meta Power (no dated metagame sample); Matchup fit and format fit (no tournament link)
• 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 (going-first/second, matchup, brick/starter rates) No Side Deck registered, so post-side power cannot be scored Usage-stat matching looks inconsistent for Extra-Deck cards: S:P Little Knight and Selene are in the Extra Deck but marked in this deck:false in usage statistics Meta Power is Provisional unless a dated metagame sample is supplied
