Mayakashi Deck #773054 — Yu-Gi-Oh! OCG

Deck — Deck Power Evaluation

Final Contextual Deck Power: 30/100 (±10 · Confidence: Low)

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

Legality

Main 55 / Extra 15 / Side 0 — status under the rules at evaluation time: Illegal. 2 violation(s).

Identity & game plan

• Win condition: Call of the Haunted chains into Zombie boss monsters (Pumpking the King of Grave Ghosts, Imsety, Nibiru, Doomking Balerdroch) and Extra-Deck Xyz/Link finishers; Disruption-heavy grind: hand traps and negates trade with the opponent while Zombie recursion rebuilds the board
• Turn 1 (going first): Open with a Call of the Haunted or Pumpking line with backup hand traps held for the opponent's response; theoretical only because the list is illegal
• Turn 2 (going second): Hold hand traps (Ash Blossom, Infinite Impermanence, Evenly Matched, Ghost Ogre and Snow Rabbit, Droll and Lock Bird) and use Zombie monsters to answer the opponent's first board
• Recovery: Recycle Call of the Haunted and Army of the Haunted from the GY, use Hubrow and Necroworld Banshee to refill, and use Zombie World for extra summons
• After siding: No side deck is registered, so there is no post-side plan in this list

Why it scores here

The deck is scored as a system, not as an average of its card scores. Its reliable opening comes from the archetype core: 21 copies of Call of the Haunted-family and related Zombie or Mayakashi cards give a 0.92 chance of at least one core card in a 5-card hand, but any single 3-copy starter is only about 0.25 to open. Its conversion is supported by boss monsters at 2800 to 3000 ATK and Extra-Deck Xyz/Link finishers, but no recorded boards exist, so the ceiling is text-based and the median is unmeasured. Interaction is dense, with 14 hand traps and 13 negation-text cards, which should help it survive disruption and go second. The list is illegal because Ash Blossom and Dominus Impulse are each run three times against a limit of two, so the score is capped at 30 and labelled theoretical only. Popularity and archetype usage did not earn points, and no card-score averaging was used.

Dimension scores

How the score was computed

Strategy profile: Midrange 85 : Stun 15 (approximate; hybrid disclosed). Structural ≈ 53, Going First ≈ 50, Going Second ≈ 60, Meta = provisional, Tournament Reliability ≈ 42. Modifiers: Banlist exposure (copy-limit violation) (-12); Illegal-cap (-9). Final formula: Theoretical only: 0.80*Structural(53) + 0.20*TournamentReliability(42) = 51 before modifiers; modifiers -12 give 39; capped at 30 because the list is Illegal (copy limit). Meta provisional.

Probability & combo summary

• Opening a starter: P(≥1) ≈ 0.25 · 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

• 21-copy archetype core gives high odds of a live opening hand
• Dense hand-trap and negation suite (14 hand traps, 13 negation-text cards) for going second
• Strong boss ATK at 2800 to 3000 across Imsety, Nibiru and Balerdroch
• Compact main deck within size rules, with 17 singletons for flexibility

Weaknesses

• Illegal list: Ash Blossom and Dominus Impulse each run 3 copies over the limit of 2
• No side deck at all, so there is no post-side adaptability
• Hand-trap-heavy construction risks dead cards when the opponent plays around them
• No recorded boards, so the combo ceiling and median cannot be verified

Critical choke points

• Call of the Haunted and its Zombie targets: losing the key Call of the Haunted removes the main engine route
• Single-copy Pumpking and Zombie World lines have no redundancy

Recommended changes

Evidence & confidence

• Verified: Legality: 2 copy-limit violations (Ash Blossom and Dominus Impulse at 3 copies each vs legal 2); Size: 55 Main, 15 Extra, 0 Side are within the OCG size rules; Limited cards Droll and Lock Bird, Foolish Burial, Harpie's Feather Duster and S:P Little Knight each run 1 copy (legal)
• Inferred: Consistency: archetype core 0.92 for at least one card in a 5-card opening hand; Going-second hand-trap coverage: 0.84 for at least one hand trap in a 6-card hand; Interaction density is high from 14 hand traps and 13 negation-text cards
• Provisional: Meta Power (null) and archetype meta-share, since no dated metagame sample exists
• 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 are absent No win-rate telemetry exists in YGOVN for going-first, going-second, matchup or brick rates Meta Power is Provisional unless a dated metagame sample is supplied Evidence inconsistency: usage statistics marks Pumpking the Great Ghost King, Officiator of Doom Samuel and other Extra-Deck cards as in this deck false although the cards list shows them in the Extra Deck; core-card presence (48) may be understated Deck title is null, so the deck is identified only by its id and archetype
