Mathmech Deck #758774 — Yu-Gi-Oh! OCG

Deck — Deck Power Evaluation

Final Contextual Deck Power: 40/100 (±8 · Confidence: Low)

• Primary strategy: Combo
• Secondary strategies: Stun
• Format: ocg

Legality

Main 40 / Extra 15 / Side 0 — status: Illegal. 3 violation(s).

Identity & game plan

• Win condition: Link and Synchro/Xyz boss monsters from the Extra Deck (Accesscode Talker, Transcode Talker, Decode Talker Heatsoul, Firewall Dragon Darkfluid, Primathmech Alembertian) built from Cyberse and Mathmech starters.; Mathmech Superfactorial and Mathmech Sigma recursion from the GY, plus Ignister searches that feed Link Summons.
• Turn 1 (going first): Open a Cyberse starter (Pikari, Backup, Achichi or Cynet Mining) with a searcher such as A.I. Connect or Cynet Mining, then Link Summon into a boss. Hand traps are mostly dead on the first turn.
• Turn 2 (going second): Hold Ash Blossom, Infinite Impermanence, Effect Veiler and Droll to answer the opponent's first summon or activation, then convert the open board with Extra Deck summons.
• Recovery: Recover through Mathmech Superfactorial and GY-based Special Summons, and Ignister searches that rebuild the starter.
• After siding: Not evaluable: the deck has no Side Deck (0 cards), so there is no post-side plan.

Why it scores here

The deck is scored as a system, not as an average of its cards, and it is capped because the list is illegal in OCG: Ash Blossom is at 3 copies (limit 2), Droll & Lock Bird at 2 (limit 1), and Called by the Grave (Forbidden) runs 1. The engine opens reasonably often: the 3-copy Ignister/Cyber starters and the searchers (A.I. Connect, Cynet Mining, Backup) give roughly 82% odds of at least one searcher in a 5-card opening hand (Inferred). The ceiling is a Link/Synchro line into a 2300+ ATK boss, but no recorded boards exist, so the combo floor and median are text-only estimates with low confidence. Interaction is dense (about 14 negation and 11 hand-trap cards, with a roughly 88% chance of a hand trap in a 6-card going-second hand, Inferred), which supports the going-second plan. Brick risk is high: 13 tech and 47 off-exact-archetype copies lower compactness, and the empty Side Deck leaves no post-side plan. Popularity and archetype usage stats were not used to raise the score.

Dimension scores

How the score was computed

Strategy profile: Combo. Structural ≈ 47.4, Going First ≈ 42, Going Second ≈ 50, Meta = provisional, Tournament Reliability ≈ 35. Modifiers: banlist_exposure (-5). Final formula: 0.80*Structural + 0.20*TournamentReliability (Meta provisional) = 0.80*47.4 + 0.20*35 = 44.9; -5 banlist-exposure modifier = 39.9, rounded to 40 and capped for illegal list (theoretical/structural only)

Probability & combo summary

• Opening a starter: P(≥1) ≈ 0.34 · 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: 11 hand traps and 14 negation-text cards.
• Searcher density gives a high chance of finding a starter.
• Full 15-card Extra Deck with several 2300+ ATK link and synchro bosses.

Weaknesses

• Illegal in OCG: three cards over their copy limit, one of them Forbidden.
• High brick and dead-card risk: 13 tech cards and many off-archetype copies.
• No Side Deck, so no post-side plan.
• No recorded combos or tournament data to validate the line.

Critical choke points

• Each engine line depends on one Cyberse starter in hand; without it the Link Summon route does not start.
• Going first, most hand traps are dead, so the opening relies on the searcher and starter.
• Forbidden Called by the Grave and over-limit Ash Blossom and Droll must be cut before the list can be scored normally.

Recommended changes

Evidence & confidence

• Verified: Legality status Illegal with three over-limit cards (Ash Blossom 3/2, Droll 2/1, Called by the Grave 1/0 Forbidden).; Main 40, Extra 15, Side 0 counts and archetype spread.; Card text for interaction and searcher roles.
• Inferred: Starter and hand-trap hand odds from the hypergeometric table.; Consistency, brick and interaction-density reads.; Going-first and going-second plan descriptions.
• Provisional: Meta power and matchup fit: no tournament link or dated metagame sample.; Going-second balance: no win-rate or split data.
• 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 for going-first, going-second, matchups or brick rates. Meta Power is provisional unless a dated metagame sample is supplied. Side Deck is empty (0 cards), so post-side adaptation cannot be assessed.
