Spellbook Deck #770621 — Yu-Gi-Oh! TCG

Deck — Deck Power Evaluation

Final Contextual Deck Power: 51/100 (±6 · Confidence: Medium)

• Primary strategy: Midrange
• Secondary strategies: Toolbox, Tempo
• Format: tcg

Legality

Main 52 / Extra 15 / Side 0 — status: Legal.

Identity & game plan

• Win condition: Quick-Play-triggered Radiant Typhoon monsters and Mystical Space Typhoon recursion pressure the board, then Link/Fusion/Xyz boss monsters (Varuroon, Fonix, Shiina, Red-Eyes Exceed) close the game.; Charmer control-steal and Link-summon chains (Wynn, Dharc, Lyna, Eria) that take over opposing monsters.
• Turn 1 (going first): Search or summon an opening Radiant Typhoon or Quick-Play engine piece with Spellbook/Charmer searchers, then use Mystical Space Typhoon and Radiant Typhoon Krosea or Swen summons to clear backrow and build a Link board.
• Turn 2 (going second): Open with Droll & Lock Bird or a Quick-Play in response to the opponent's search, then use Radiant Typhoon Varuroon negation and Totem Bird destruction to disrupt their board while summoning from hand.
• Recovery: Recur Mystical Space Typhoon, Quick-Play Spells and Radiant Typhoon monsters from the GY with Radiant Typhoon Ascendance, Manifestation and Chant; Dark Time Wizard and Foolish Graverobber add resources back.
• After siding: Not available: the deck runs no Side Deck (Side Deck size 0), so there is no post-side plan.

Why it scores here

The deck's score comes from its system, not from averaging its cards. Its 30 searcher-text cards give a 99% chance of at least one searcher in a 5-card opening hand, and the three Mystical Space Typhoons with the Radiant Typhoon summons give it a real quick-play engine. Interaction is broad: 14 removal-text cards, Varuroon's negation, Totem Bird and multiple control-steal flips, and the Extra Deck supplies several 2800+ ATK or DEF closers. Against that, the list mixes four sub-archetypes (Radiant Typhoon 21, Charmer 15, Spellbook 7, Possessed/Dark Time Wizard) with only 10.4% exact-name purity, has no Side Deck, and has no recorded boards, so the combo ceiling and median are inferred from text only. Archetype popularity and usage stats were not credited; they show the list is only 2 of 25 standard core cards, which lowers its score.

Dimension scores

How the score was computed

Strategy profile: Midrange primary; secondary Toolbox reflected in the sub-archetype and tech-card dimensions (D10, D11, D14) rather than by a separate weight set. Structural ≈ 57, Going First ≈ 58, Going Second ≈ 52, Meta = provisional, Tournament Reliability ≈ 50. Modifiers: No side deck (-2); Engine conflicts / low archetype purity (-3). Final formula: 0.80*Structural + 0.20*TournamentReliability (Meta provisional); Structural 57.4 -> 57, TR 50, modifiers -5 -> 51

Probability & combo summary

• Opening a starter: P(≥1) ≈ 0.27 · 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

• Very high searcher density (30 searcher-text cards) gives near-certain access to an engine piece.
• Broad removal and negation suite (14 removal-text, 2 negation-text, Totem Bird and Varuroon).
• Multiple Extra Deck closers at 2400+ ATK or DEF, with several Link summons available.
• Recursion of MST and Quick-Play Spells from the GY gives a resource loop after disruption.

Weaknesses

• No Side Deck, so there is no way to adapt between games.
• Four or five sub-archetypes compete for the same slots, giving low exact purity and brick risk.
• Only one hand trap for going second.
• No recorded combo or tournament data, so the ceiling and floor are unverified.

Critical choke points

• Mystical Space Typhoon count (3) gates much of the Radiant Typhoon quick-play engine.
• Single Droll & Lock Bird is the only hand trap against going-second lines.
• Limited cards (Droll & Lock Bird, Radiant Typhoon Chant, S:P Little Knight) are each capped at one copy.

Recommended changes

Evidence & confidence

• Verified: Legal in tcg: 52 main (40-60), 15 extra (0-15), 0 side; no violations.; Limited cards (Droll & Lock Bird, Radiant Typhoon Chant, S:P Little Knight) each run 1 copy, within limit.; Copy histogram sums correctly (24x1 + 2x2 + 8x3 = 52); Extra Deck breakdown 10 Link, 3 Fusion, 2 Xyz.; Hypergeometric draw odds for 3-copy cards: P(>=1 in hand5) = 0.2663 (recomputed, matches evidence).
• Observed: Usage stats available: 2 of 25 standard Spellbook core cards present (8%).
• Inferred: Engine consistency and brick risk from searcher density and copy distribution.; Interaction and going-second strength from card text (negation, removal, hand trap).; Going-first and going-second plans from card text and archetype composition.
• Provisional: Median output (D4) and ceiling (D3) are not measured: no combo boards supplied.; Meta Power and matchup fit are not measured: no tournament link or dated metagame sample.
• 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 going-first, going-second, matchup or brick rates. Meta Power is Provisional: no dated metagame sample supplied. No Side Deck in the export, so post-side behaviour cannot be evaluated.
