Magikey Deck #767043 — Yu-Gi-Oh! OCG

Deck — Deck Power Evaluation

Final Contextual Deck Power: 48/100 (±8 · Confidence: Medium)

• Primary strategy: Midrange
• Secondary strategies: Toolbox, Ritual/Fusion engine
• Format: ocg

Legality

Main 57 / Extra 15 / Side 0 — status: Legal.

Identity & game plan

• Win condition: Ritual or Fusion Summon Magikey boss monsters (Magikey Mechmusket / Mechmortar via Magikey Maftea; Magikey Dragon - Andrabime, Magikey Deity - Ashtartu) and convert through 2800-3000 ATK bodies; Link and XYZ extenders (Knightmare Phoenix, Silhouhatte Rabbit, I:P Masquerena, Link Spider, Imduk, Grenosaurus Giga-Cannon) plus D.D. Crow / Artifact Lancea / Ghost Belle hand-trap interaction
• Turn 1 (going first): Normal Summon Clavkiys or Mafteal, search Magikey Maftea or a Magikey monster with Preparation of Rites, Magikey World or Manju, then Ritual or Fusion Summon a boss
• Turn 2 (going second): Hand traps (D.D. Crow, Artifact Lancea, Ghost Belle & Haunted Mansion, PSY-Framegear Gamma) and Magikey Unlocking / Magikey Duo to break the opponent's first board, then rebuild through Maftea
• Recovery: Searchers (Magikey World, Manju, Preparation of Rites, Reinforcement of the Army, Magikey Duo) and Magikey Maftea recursion from the GY to rebuild after a board wipe
• After siding: Not applicable: the deck runs no Side Deck, so there is no post-side plan

Why it scores here

The deck reliably opens its Magikey core: about 86 percent of opening hands going first (hypergeometric, Inferred) contain at least one of the 18 archetype-core copies, and 16 searcher-text cards give it real redundancy. Its ceiling comes from Ritual and Fusion bosses that reach 2800 to 3000 ATK, and it has about 16 removal and 10 negation effects of text-level interaction. The score is held back by a main deck with only 37.5 percent exact-name Magikey purity, many situational spells (Raigeki, Harpie's Feather Duster, Instant Fusion, Dragon's Mirror, High Ritual Art) that add brick risk, and no Side Deck, so there is no post-side plan. No recorded boards, meta-share or per-pilot results exist, so popularity did not earn points and the card scores were not averaged. The result is a Medium-confidence read built on the system, with Meta Power left provisional.

Dimension scores

How the score was computed

Strategy profile: Midrange profile only; Toolbox secondary noted, not blended. Structural ≈ 55, Going First ≈ 58, Going Second ≈ 50, Meta = provisional, Tournament Reliability ≈ 48. Modifiers: engine conflicts (-3); weak post-side plan (-2). Final formula: 0.80*Structural + 0.20*TournamentReliability + ContextModifiers (Meta provisional): 0.80*54.6 + 0.20*48 - 5 = 48.3

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

• Archetype-core density (18 copies) gives about 86 percent opening-hand access to a Magikey starter
• 16 searcher-text cards and recursion through Magikey Maftea support grind
• Layered interaction from 16 removal-text and 10 negation-text cards plus 7 hand traps
• Strong Extra Deck closers (Ashtartu 3000, Andrabime 2800, Transfurlmine 2800)

Weaknesses

• Only 37.5 percent exact-name Magikey purity; 45 off-archetype main deck copies
• Many situational or dead-without-target spells (Raigeki, Harpie's Feather Duster, Instant Fusion, High Ritual Art, Dragon's Mirror)
• No Side Deck, so no post-side adaptation
• Multiple summoning mechanics (Ritual, Fusion, Synchro, Link, XYZ) raise error rate and pilot demand

Critical choke points

• Magikey Maftea (2 copies) is the single gateway to both the Ritual and Fusion bosses
• Ritual and Fusion bosses need Maftea plus material, so one disruption to the starter can stop the whole line

Recommended changes

Evidence & confidence

• Verified: Legal status: 57 Main and 15 Extra cards within size rules, no violations; Limited cards (Harpie's Feather Duster, Instant Fusion, PSY-Framegear Gamma, Reinforcement of the Army, Terraforming) each run 1 copy, within the limit of 1; Exact-name Magikey purity 37.5 percent (27 of 72 archetype-tagged copies); 11 of 25 usage-core cards present; 14 core cards missing; No tournament link and no recorded combos
• Inferred: P(at least one archetype-core copy in opening 5) about 0.86; Brick risk from situational spells and off-archetype cards; Maftea as single-point starter for Ritual and Fusion lines; Interaction density from text read (16 removal, 10 negation)
• Provisional: Meta Power and D13 matchup fit: no 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; going-first/second, matchup, brick and OTK rates are Inferred or Unknown Meta Power is Provisional without a dated metagame sample no Side Deck supplied, so post-side performance cannot be assessed
