Mathmech Deck #773228 — Yu-Gi-Oh! OCG

Deck — Deck Power Evaluation

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

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

Legality

Main 55 / Extra 15 / Side 0 — status under the rules at evaluation time: Illegal. 1 violation(s).

Identity & game plan

• Win condition: Link and Synchro/Xyz boss plays (Firewall Dragon Darkfluid - Neo Tempest Terahertz, Decode Talker Heatsoul, Primathmech Alembertian) built from Cyberse/Mathmech starters; no combo boards recorded, so the win condition is text-inferred only (Inferred).; Mulcharmy and @Ignister draw/search engines that grind card advantage over several turns (Inferred).
• Turn 1 (going first): Open a Cyberse/Mathmech starter (Pikari, Backup, Mathmech Diameter, Cynet Mining path) and build toward a Link-3 or Link-4 boss while holding one or two hand traps (Inferred).
• Turn 2 (going second): Use hand traps (Infinite Impermanence, Ash Blossom, Evenly Matched, Effect Veiler, Ghost Ogre, Droll & Lock Bird, Solemn Judgment) to disrupt the opponent's first summon, then rebuild a board from the remaining cards (Inferred).
• Recovery: Recover via Mulcharmy draw effects and @Ignister/Code Talker searchers from the Deck, with limited recursion from the GY (Inferred).
• 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 card scores, and its legality is Illegal: three copies of Ash Blossom & Joyous Spring exceed the OCG Semi-Limited limit of two, so the score is capped at 30 and labelled theoretical and structural-only. Its strongest structural feature is interaction density: 19 hand traps and about 17 negation-text cards give a 0.93 chance of at least one hand trap in a going-second six-card hand (Inferred). Its engine coherence is weak. Only 8 of 70 copies are exact Mathmech names (11.4% purity), and the deck mixes Mathmech, @Ignister, Mulcharmy, Code Talker, Cyber, Salamangreat, PSY-Frame and Knightmare, so starters conflict and bricks are likely. The archetype core has an estimated 0.81 chance of at least one starter in a five-card opening hand, but this is a hypergeometric estimate over a fragmented engine. No combo boards, guides, or tournament results exist, so floor, median and ceiling output, and matchup fit, are unmeasured. Popularity of the archetype did not earn points, and no points were given for the Mathmech name alone.

Dimension scores

How the score was computed

Strategy profile: Toolbox. Structural ≈ 52, Going First ≈ 40, Going Second ≈ 60, Meta = provisional, Tournament Reliability ≈ 35. Modifiers: Illegal copy-limit violation (Ash Blossom x3, limit 2) (-9); Engine conflicts across sub-archetypes (-4); Banlist exposure (-2). Final formula: Illegal cap applied: Structural 52 with Toolbox weights; uncapped 0.80*52 + 0.20*35 = 48.6, minus modifiers (-9) gives about 40; capped at 30 because the deck is Illegal. Theoretical and structural-only; Meta Power is null (provisional).

Probability & combo summary

• Opening a starter: P(≥1) ≈ 0.81 · 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 hand-trap and negation suite: 19 hand traps and about 17 negation-text cards, giving high going-second disruption (Inferred).
• Layered end-board interaction (Infinite Impermanence, Ash Blossom, Evenly Matched, Solemn Judgment, Droll & Lock Bird) (Inferred).
• Flexible Extra Deck with 10 Link monsters plus Synchro, Xyz and Fusion options (Verified composition).

Weaknesses

• Illegal as built: Ash Blossom & Joyous Spring is over its Semi-Limited copy limit (Verified).
• Low archetype coherence: only 11.4% exact-name purity, with many sub-archetypes (Verified composition).
• Brick risk: 19 hand traps and several sub-archetype starters compete for the same hand slots (Inferred).
• No Side Deck, so no post-side adaptability (Verified).

Critical choke points

• The archetype starter group (15 copies) is spread across several sub-archetypes, so one starter often fails to find its partner (Inferred).
• Limited cards at one copy each (Droll & Lock Bird, Solemn Judgment, Harpie's Feather Duster, Mathmech Circular, PSY-Framegear Gamma) are single-point failures if drawn dead or banished (Verified).

Recommended changes

Evidence & confidence

• Verified: Main Deck 55, Extra Deck 15, Side Deck 0 are within OCG size rules.; Ash Blossom & Joyous Spring runs 3 copies against a legal limit of 2 (Semi-Limited).; Five Limited cards each run one copy, which is legal.; Archetype purity is 11.4% (8 of 70 cards named Mathmech).
• Inferred: Hypergeometric starter and hand-trap probabilities (0.81 and 0.93).; Brick and engine-conflict estimates from card text and composition.; Going-first and going-second plan descriptions.
• Provisional: Meta Power (null) and matchup/format fit (D13).; Tournament reliability.
• Data gaps: No combos supplied: 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: going-first/second, matchup and brick/starter rates are Inferred or Unknown. Meta Power is Provisional unless a dated metagame sample is supplied. No guides attached for the archetype. No Side Deck, so post-side scoring is at its floor.
