Deck — Deck Power Evaluation

Final Contextual Deck Power: 30/100 (±6 · Confidence: Low)

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

Legality

Main 60 / Extra 15 / Side 0 — status under the rules at evaluation time: Illegal. 3 violation(s).

Identity & game plan

• Win condition: Charmer / Familiar-Possessed Fusion and Link boards plus Fairy Tail and Possessed field presence (Inferred from card text; no recorded boards); Dark Magician / Shining Sarcophagus Horus recursion with Imsety and Dark Magician of Destruction (Inferred)
• Turn 1 (going first): Open Spellbook searchers (Spellbook of Secrets, Spellbook Magician of Prophecy) to reach Spellbook Fusion/Link engines; Charmer flip-control monsters as board takers (Inferred)
• Turn 2 (going second): Hand traps Ash Blossom, Maxx C, Droll & Lock Bird, Effect Veiler to stall the opponent's Summons before the Charmer engine comes online (Inferred)
• Recovery: Recursion from GY via Familiar-Possessed, Awakening of the Possessed monsters and Spellbook of the Grand Circle banish-Fusion (Inferred)
• After siding: No side deck is registered, so no post-side plan can be evaluated (Provisional)

Why it scores here

The deck is a 39-distinct-card Spellbook-named shell that in practice runs at least six sub-archetypes (Charmer, Fairy Tail, Possessed, Dark Magician, Horus, Familiar-Possessed), with only 14.7% exact-name archetype purity. Its opening access is strong: the 33 searcher-text cards give a 98.5% chance of at least one searcher in a 5-card opening hand (hypergeometric, Inferred), and the 14-card archetype core gives about 78% to open at least one core card. Interaction is layered: 5 hand-trap-tagged cards plus Lyna/Eria/Aussa-style flip control and Ash Blossom, giving a 42% chance of at least one hand trap in a going-second 6-card hand. Conversion and median output could not be measured because no combos were supplied, so the ceiling and floor scores rest on text reads only, not recorded boards. The score does not come from the popularity of the Spellbook name, and no card scores were averaged; it is capped low because three Forbidden cards (Charmer Quartet in Bloom, Red-Eyes Dark Dragoon, Cross-Sheep) make the list illegal in OCG.

Dimension scores

How the score was computed

Strategy profile: Midrange. Structural ≈ 50, Going First ≈ 52, Going Second ≈ 46, Meta = provisional, Tournament Reliability ≈ 45. Modifiers: banlist_exposure (-12); illegal_cap (-7). Final formula: Structural 50.3 -> 0.80*50 + 0.20*45 = 49 before modifiers; banlist exposure -12 gives 37; illegal-deck cap sets the final score at 30 (Meta provisional)

Probability & combo summary

• Opening a starter: P(≥1) ≈ 0.99 · 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 searcher text (33 cards) gives near-certain access to a Spellbook/Charmer searcher in the opening hand
• Layered hand-trap and negation coverage (Ash Blossom, Maxx C, Droll & Lock Bird, Effect Veiler)
• Strong Extra Deck threats (Imsety, Perfectron, Quintet Magician, Dark Magician of Destruction)

Weaknesses

• Illegal list: three Forbidden cards cannot be played in OCG
• Low archetype purity (14.7%) means engines cross sub-archetypes and compete for slots
• No side deck, so no post-side adaptation

Critical choke points

• Charmer engine depends on the Forbidden Charmer Quartet in Bloom; without it the Link/Fusion route needs replacement
• Cross-Sheep and Red-Eyes Dark Dragoon are Forbidden and remove Extra Deck options

Recommended changes

Evidence & confidence

• Verified: Legality: 3 Forbidden cards in deck, illegal status; Composition counts: 60 main, 15 extra, 0 side; 14.7% exact archetype purity; Banlist statuses for Limited and Semi-Limited cards in deck
• Inferred: Searcher access 0.985 for 5-card opening hand; Core access 0.776 for opening hand; Hand-trap access 0.421 going second; Strategy and turn-1/turn-2 plans from card text
• Provisional: Meta Power (no dated meta sample); Matchup fit (no tournament data)
• Data gaps: no combos supplied: combo floor, median and ceiling are text-only inference no tournament link: archetype meta-share and per-pilot record absent no win-rate telemetry: going-first/second, matchup and brick rates are inferred Meta Power is provisional unless a dated metagame sample is supplied no side deck registered
