Spellbook Deck #774230 — Yu-Gi-Oh! Master Duel

Deck — Deck Power Evaluation

Final Contextual Deck Power: 60/100 (±7 · Confidence: Medium)

• Primary strategy: Midrange
• Secondary strategies: Toolbox, Fusion, Link
• Format: master-duel

Legality

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

Identity & game plan

• Win condition: Large Fusion, Link and Synchro beaters (Red-Eyes Dark Dragoon 3000, Zoroa the Magistus Verethragna 2900, Dark Magician of Destruction 2800, Charmers of the Grand Circle 1850) backed by flip-effect control steals from the Charmer suite (Inferred from card text; no recorded line).; Charmer control swings: the five Charmer flip monsters take control of an opponent monster of a matching attribute (Verified card text).
• Turn 1 (going first): Inferred from card text, not a recorded line: use the three Spellbook of the Grand Circle and the Spellbook of Secrets / Spellbook Magician of Prophecy searchers to gather Charmers and Magistus monsters, then convert through the Extra Deck, holding Ash Blossom and Maxx C as backup.
• Turn 2 (going second): Inferred from card text: keep Ash Blossom, Droll and Lock Bird and Maxx C for the first opponent summon or activation (65 percent chance of at least one hand trap in a 6-card hand), use Forbidden Droplet and Crossout Designator to break the first board, then rebuild through the searchers.
• Recovery: Inferred: 20 searcher-text cards and GY recursion (Spenta banish, Grand Circle banish) restore the hand after disruption; hand traps spend cards that the searchers replace.
• After siding: None built: the deck runs 0 side cards and Master Duel ladder play has no sideboard, so no post-side plan exists to score.

Why it scores here

The score comes from the deck as a system: a 20-card searcher base (P of at least one searcher in an opening 5 is about 0.98) reaches one of several engines (Spellbook, Charmer, Magistus, Dark Magician, Possessed), and the Extra Deck supplies Fusion, Link and Synchro beaters up to 3000 ATK. Interaction is the strongest part of the list: six hand traps, two Forbidden Droplet, Crossout Designator, and five Charmer flip steals give layered answers on both turns. Score is held back because the sub-engines split the deck (only about 9 cards each for Spellbook, Charmer, and Magistus, plus 4 Dark Magician cards and 2 Possessed cards), so several cards (Gaze of Timaeus, Possessed Partnerships, Shining Sarcophagus) need a specific engine on board to function. No combo boards were recorded, so the ceiling and median are text-inferred and labelled as such. Popularity or archetype usage did not earn points, and no card scores were averaged into the deck score.

Dimension scores

How the score was computed

Strategy profile: Midrange. Structural ≈ 62, Going First ≈ 68, Going Second ≈ 65, Meta = provisional, Tournament Reliability ≈ 55. Modifiers: Engine conflicts across sub-archetypes (-3); Layered hand-trap and negation suite (2). Final formula: 0.80*Structural + 0.20*TournamentReliability + ContextModifiers (Meta provisional): 0.80*61.9 + 0.20*55 - 1 = 59.5, rounded to 60

Probability & combo summary

• Opening a starter: P(≥1) ≈ 0.98 · 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 (20 searcher-text cards, P at least one in opening 5 about 0.98)
• Layered interaction: 6 hand traps, 2 Forbidden Droplet, Crossout Designator, 5 Charmer flip steals
• Multiple summon routes and GY recursion give independent lines after one disruption
• Strong Extra Deck end-boards (2800 to 3000 ATK)

Weaknesses

• Sub-engines split across Spellbook, Charmer, Magistus, Dark Magician and Possessed; only 16.4 percent exact-name purity
• Several dead-without-engine cards (Gaze of Timaeus, Possessed Partnerships, Shining Sarcophagus)
• No recorded combo boards, so the median and ceiling are text-inferred
• No sideboard, no meta sample, no tournament link

Critical choke points

• Spellbook of the Grand Circle (3 copies) is the main Charmer gate; without it the 4-Charmer fetch and Charmers of the Grand Circle are unreachable (Inferred)
• Hand-trap dependence when going second: about 35 percent of 6-card hands have no hand trap (Inferred)

Recommended changes

Evidence & confidence

• Verified: Legality: Legal, 40 main / 15 extra / 0 side inside Master Duel size rules; Copy limits: Crossout Designator 1 of 1 (Limited), Maxx C 1 of 1 (Limited), Droll and Lock Bird 2 of 2 (Semi-Limited); Composition counts and Extra Deck breakdown (8 Fusion, 6 Link, 1 Synchro) match the card list; Card text for all listed cards from the evidence excerpts
• Observed: Usage statistics show archetype core cards, but only 12 of 25 core cards present (48 percent); in this deck flags for Extra Deck refs look mismatched, so this figure is unreliable
• Inferred: Engine accessibility and brick estimates from hypergeometric draws; Going-first and going-second plans from card text; Interaction quality from text (negation and removal hints)
• Provisional: Median and floor (no combo boards); Matchup and format fit (no tournament context or dated meta); Side adaptability (no sideboard in format)
• Data gaps: no combos supplied: combo floor, median and ceiling are text-only inference no tournament link: archetype meta-share and pilot match record absent usage statistics in this deck flags for Extra Deck refs (Charmers of the Grand Circle, Artemis, Endymion and others) read false although the cards are present, so core-card presence is unreliable guide snippet (guide 321) describes a different build and cards not in this deck; not attributed no win-rate telemetry: going-first/second, matchup, brick and starter rates are Inferred or Unknown Meta Power is Provisional: no dated metagame sample supplied No sideboard in Master Duel: D12 is a neutral placeholder
