Mayakashi Deck #772171 — Yu-Gi-Oh! OCG

Deck — Deck Power Evaluation

Final Contextual Deck Power: 36/100 (±8 · Confidence: Low)

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

Legality

Main 57 / Extra 15 / Side 0 — status under the rules at evaluation time: Illegal. 1 violation(s).

Identity & game plan

• Win condition: Zombie/Mayakashi board built from Call of the Haunted recursion and Pumpking the King of Grave Ghosts, converted into Link/XYZ/Synchro boss monsters; Eldlich the Mad Golden Lord (fusion) and Vampire/Zombie link boss lines when the main-deck engine misses
• Turn 1 (going first): Open a Zombie or Mayakashi starter (Mayakashi Return, Ectoplasmic Fortification or Glow-Up Bloom searches), build a Link or Synchro board, and hold Ash Blossom and Ghost Belle as hand traps for the first opposing response
• Turn 2 (going second): Use Ash Blossom, Ghost Mourner and Ghost Belle to negate the opponent's first summon or search, then rebuild a board from the graveyard with Call of the Haunted and Gozuki
• Recovery: Recycle Zombie monsters from the graveyard through Curse of the Ancient Turtle, Changshi the Spiridao, Gozuki and Glow-Up Bloom, and reuse Zombie World's field effects
• After siding: No side deck is registered in the export, so no post-side plan can be assessed

Why it scores here

The deck opens a searcher-backed starter in most hands (P(at least one searcher-text card in a 5-card hand) ≈ 0.77) but its core engine is thin, since each Call of the Haunted and Pumpking copy only has about a 0.24 chance of appearing in an opening hand. Its strongest value is interaction: seven hand traps and thirteen negation-text cards let it answer the first opposing play at the cost of a card, which carries a fair going-second score. Conversion and median output could not be measured because the export contains no parseable boards, so the ceiling is text-only inference. Popularity and archetype share do not add points here, and the score is not an average of individual card scores. The Ash Blossom copy-limit violation caps the score, because the list is illegal as submitted.

Dimension scores

How the score was computed

Strategy profile: Midrange. Structural ≈ 48.4, Going First ≈ 48, Going Second ≈ 52, Meta = provisional, Tournament Reliability ≈ 35. Modifiers: Illegal copy-limit violation (-10). Final formula: 0.80*Structural + 0.20*TournamentReliability (Meta provisional) + ContextModifiers; illegal-list cap applied as a -10 modifier, so the result is theoretical/structural only

Probability & combo summary

• Opening a starter: P(≥1) ≈ 0.77 · 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

• Seven hand traps and thirteen negation-text cards give broad first-response interaction
• Searcher-text coverage of 14 cards keeps a starter reachable in most opening hands
• Extra Deck has 15 distinct high-ATK options across Link, XYZ, Fusion and Synchro with no single dependency

Weaknesses

• Illegal as submitted: three copies of Ash Blossom & Joyous Spring against an OCG limit of two
• Engine pieces are thin: each 3-copy Call of the Haunted or Pumpking has only about a 0.24 chance of appearing in an opening hand
• No side deck registered, so there is no post-side plan and no best-of-3 adaptability

Critical choke points

• Ash Blossom copy limit must be fixed before this list can be played in an OCG event
• Call of the Haunted is a single copy and is the only recursion for Pumpking-based boards

Recommended changes

Evidence & confidence

• Verified: Main deck 57 and Extra Deck 15 are within OCG size rules; Ash Blossom & Joyous Spring runs 3 copies against an OCG limit of 2; Side deck is empty in the export; Card text and banlist status for every card are present in the evidence pack
• Inferred: Opening-hand starter probabilities from the hypergeometric draw table; Hand-trap coverage and brick-rate estimates from composition and card text; Going-first and going-second strength read from interaction density
• Provisional: Meta power (no dated metagame sample); Format fit and matchup coverage (no tournament link)
• Data gaps: No combos supplied, so floor, median and ceiling are text-only inference No tournament link, so archetype meta-share and per-pilot match record are absent No win-rate telemetry; going-first, going-second, matchup and brick rates are Inferred or Unknown Meta Power is provisional unless a dated metagame sample is supplied No side deck registered in the export
