Mathmech Deck #774600 — Yu-Gi-Oh! TCG

Deck — Deck Power Evaluation

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

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

Legality

Main 56 / Extra 15 / Side 0 — status: Illegal. 1 violation(s).

Identity & game plan

• Win condition: Xyz pressure from a mixed Extra Deck (Ryzeal Detonator, Number 39, Primathmech, Ryzeal Duo Drive, Tornado Dragon) built on Zubaba/Gagaga/Gogogo/Dododo level-4 bodies, with Mathmech Circular and Ryzeal as the secondary engines.; Board-clearing and hand-disruption (Raigeki, Harpie's Feather Duster, Typhoon, Solemn Judgment, Droll & Lock Bird) followed by a single Xyz beater.
• Turn 1 (going first): Search and summon a Gagaga/Dododo body from hand (Gagaga Magic, Dododo Warrior, Onomatopaira, Gogogo Goblindbergh), then convert into one Xyz; the 2-card bootstrap is Inferred and depends on a conflicting mix of archetypes.
• Turn 2 (going second): Hold Ash Blossom, Infinite Impermanence, Evenly Matched, Droll & Lock Bird and Solemn Judgment for the opponent's first starter or search, then rebuild with one Xyz (Inferred).
• Recovery: Recurring Gagaga/Dododo bodies from GY through Onomatokage, Gagagaga Girl and Mathmech Superfactorial; recovery depends on the Extra Deck staying intact after a board wipe (Inferred).
• After siding: No side deck is registered, so there is no post-side plan; a best-of-3 event would require a new 15-card side list.

Why it scores here

The deck is a Toolbox-style pile of several sub-archetypes (Gagaga, Dododo, Ryzeal, Mathmech, Number, Primathmech) with only 8.5% exact-name Mathmech purity, so its engine is spread across incompatible starters. The archetype core group gives about an 89% chance of at least one core card in a 5-card opening hand (Inferred from the hypergeometric proxy), which keeps the engine accessible, but that is not the same as a consistent plan. Interaction is the strongest part of the system: Typhoon, Raigeki, Harpie's Feather Duster, Solemn Judgment, Droll & Lock Bird, Infinite Impermanence and Evenly Matched cover the board and the hand, and Ash Blossom is a second hand-trap layer. The deck has no recorded boards, no median output data, and no side deck, so floor, median and ceiling are all text-only inferences and none is reported as an average. Usage statistics confirm the deck is a real accessible list, but only 10 of 25 core archetype cards are present, and that did not earn points. The deck is Illegal because it runs 3 copies of Ash Blossom & Joyous Spring against a Semi-Limited limit of 2, so this is a theoretical, structural-only score capped low.

Dimension scores

How the score was computed

Strategy profile: Toolbox primary with Control secondary; Toolbox profile applied as recorded. Structural ≈ 52, Going First ≈ 55, Going Second ≈ 55, Meta = provisional, Tournament Reliability ≈ 40. Modifiers: banlist/copy-limit exposure (-10); engine conflicts (-2). Final formula: 0.80*Structural + 0.20*TournamentReliability (Meta provisional) = 49.6 before modifiers; capped to 30 because the deck is Illegal (theoretical/structural-only score)

Probability & combo summary

• Opening a starter: P(≥1) ≈ 0.89 · 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

• Dense interaction suite: Typhoon, Raigeki, Harpie's Feather Duster, Solemn Judgment, Droll & Lock Bird, Infinite Impermanence, Evenly Matched, Ash Blossom
• Strong Extra Deck closers: Ryzeal Detonator, Number 39, Primathmech Alembertian, Ryzeal Duo Drive
• Archetype-core presence is high (about 89% for at least one core card in hand 5)

Weaknesses

• Illegal copy count on Ash Blossom & Joyous Spring (3 vs limit 2)
• Low archetype purity (8.5% exact Mathmech) and conflicting sub-archetype engines
• No side deck and no recorded boards, so floor, median and post-side performance are unknown
• Heavy Extra Deck spread (15 distinct Xyz, all single copies) with unfocused material requirements

Critical choke points

• Single Ryzeal or Mathmech Xyz access depends on specific level-4 bodies being drawn
• Ash Blossom and Infinite Impermanence overlap as hand-trap answers, leaving few other answers if both are used

Recommended changes

Evidence & confidence

• Verified: Illegal status: Ash Blossom & Joyous Spring runs 3 copies vs Semi-Limited legal limit of 2; Main deck 56 cards and Extra Deck 15 cards are within size rules; Banlist statuses for all restricted cards as listed in evidence
• Observed: Usage statistics: 10 of 25 archetype core cards present (40%)
• Inferred: Archetype core P(>=1 in 5-card hand) ~0.89 from hypergeometric proxy; Interaction density and hand-trap coverage read from card text; Recovery and Xyz routes read from card text
• Provisional: Meta Power and matchup fit (no dated meta sample or tournament link)
• Data gaps: no combos supplied - combo floor/median/ceiling is text-only inference no tournament link - archetype meta-share and per-pilot match record absent no side deck registered - post-side plan unknown no win-rate telemetry exists in YGOVN - going-first/second, matchup and brick rates are Inferred or Unknown Meta Power is Provisional unless a dated metagame sample is supplied
