Mathmech Deck #775266 — Yu-Gi-Oh! OCG

Deck — Deck Power Evaluation

Final Contextual Deck Power: 35/100 (±10 · Confidence: Low)

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

Legality

Main 54 / Extra 16 / Side 0 — status under the rules at evaluation time: Illegal. 8 violation(s).

Identity & game plan

• Win condition: Link Summon Cyberse boards (Firewall Dragon Darkfluid, Firewall Dragon Singularity, Allied Code Talker, Transcode Talker) and attack with their ATK; the win is structural only, as no combo boards were supplied (Inferred); Mathmech / Ignister Level-4 and Link pressure through Mathmech Circular and Primathmech Alembertian (Inferred)
• Turn 1 (going first): Open a Cyberse starter from the Ignister/Mathmech core (Achichi, Pikari, Backup, Hiyari, A.I. Connect or Cynet Mining), search an enabler, and keep hand traps (Ash, Infinite Impermanence, Effect Veiler) for the opponent's turn (Inferred)
• Turn 2 (going second): Hold 2-3 hand traps (Ash, Droll, Maxx C, Effect Veiler, Infinite Impermanence) to answer the first summon or search and then rebuild through Link Summons from the Extra Deck (Inferred)
• Recovery: Recover from interruption with Mathmech Equation, Mathmech Addition/Subtraction and Ignister A.I.Land to re-summon Level 4 monsters from the GY or hand (Inferred)
• After siding: No Side Deck is registered (side_count 0), so there is no post-side plan; side coverage is absent and must be scored as a gap

Why it scores here

This OCG list is Illegal as submitted: it runs 16 Extra Deck cards against a 15-card cap, exceeds the copy limits on Ash Blossom, Solemn Judgment, Maxx C and Droll & Lock Bird, and includes Forbidden cards (Called by the Grave x2, Link Decoder, Splash Mage). Under the rubric it therefore receives only a theoretical, structural-only read capped low. The structural read rests on the Ignister/Mathmech core, which is reliably accessible in the opening hand (P at least one core piece in a 5-card hand is about 0.86, Inferred) and on a dense hand-trap and negation suite that gives interaction and going-second value (D7 and D8). Consistency and conversion are held back by the 8.6% exact-archetype purity, 64 off-archetype copies, 19 singleton slots and the absence of any recorded combo boards, so the median and ceiling could not be separated. No side deck is registered, and there is no tournament or meta sample, so Meta Power is null and tournament reliability is low. The score was not produced by averaging the card scores or by the archetype's popularity; the usage stats confirm the list is real but do not add points.

Dimension scores

How the score was computed

Strategy profile: Midrange. Structural ≈ 48, Going First ≈ 45, Going Second ≈ 58, Meta = provisional, Tournament Reliability ≈ 40. Modifiers: banlist_and_size_exposure (-12). Final formula: Illegal theoretical cap: 0.80*Structural + 0.20*TournamentReliability + ContextModifiers (Meta provisional); (0.80*48.2 + 0.20*40 - 12) = 34.6, rounded to 35

Probability & combo summary

• Opening a starter: P(≥1) ≈ 0.86 · key two-card combo ≈ — · full-brick estimate ≈ 0.14 (all Inferred)
• Combo output: best PowerIndex —, median —, board-per-starter —
• Turn order: 0 going-first lines vs 0 going-second lines

Strengths

• Ignister/Mathmech core is reliably accessible in the opening hand (Inferred)
• Dense hand-trap and negation suite supports going-second interaction (Inferred)
• Link-based boards reach high ATK when the Extra Deck is accessed (Inferred)

Weaknesses

• Illegal in OCG: copy-limit, Extra Deck size, and Forbidden card violations
• Low exact-archetype purity (8.6%) and many off-archetype copies
• No Side Deck, so no post-side adaptability
• No recorded combo boards, so ceiling and median are unmeasured

Critical choke points

• Extra Deck Link access (Forbidden Link Decoder and Splash Mage must be removed)
• Hand-trap dependence on going second
• Single-copy Mathmech Circular is Limited and gates the Mathmech Extra Deck line

Recommended changes

Evidence & confidence

• Verified: Legality status Illegal with copy-limit, Forbidden, and Extra Deck size violations; Main count 54 within 40-60; Extra count 16; Side count 0; Card text, banlist status and copy counts for each card; Archetype purity 8.6% and copy histogram
• Inferred: Starter accessibility from hypergeometric draw estimates (0.86 core piece in hand of 5); Going-second interaction density from hand-trap text; Link-based closing power from card stats and text; Pilotability and brick-risk estimates from composition
• Provisional: Meta and matchup fit (no tournament link, no dated meta sample); Post-side adaptability (no Side Deck)
• Data gaps: No combos supplied: combo floor, median and ceiling are text-only inference No tournament link: archetype meta-share and per-pilot record are absent No win-rate telemetry exists for going-first, going-second, matchup or brick/starter rates No Side Deck registered (side_count 0) Meta Power is provisional unless a dated metagame sample is supplied
