Mathmech Deck #762131 — Yu-Gi-Oh! Master Duel

Deck — Deck Power Evaluation

Final Contextual Deck Power: 59/100 (±5 · Confidence: Medium)

• Primary strategy: Midrange
• Secondary strategies: Stun, Toolbox
• Format: master-duel

Legality

Main 45 / Extra 15 / Side 0 — status: Legal.

Identity & game plan

• Win condition: Link and Xyz beatsticks from the Extra Deck (Accesscode Talker, Transcode Talker, Firewall Dragon Darkfluid, Primathmech Alembertian/Laplacian) carried by Cyberse engine searches and 2300+ ATK Link-3 to Link-5 bosses; Mathmech Circular and Mathmech Diameter/Sigma engine plays into Xyz and Synchro lines, with Primathmech Laplacian as a Xyz finisher
• Turn 1 (going first): Open Cyberse starters (Backup, Pikari, Micro Coder, Wizard @Ignister) and search through Ignister/Mathmech chains into a Link-3 or Link-4 boss, keeping Ash Blossom and Infinite Impermanence up for the opponent's first interaction
• Turn 2 (going second): Use hand traps (Ash Blossom, Infinite Impermanence, Droll and Lock Bird, Maxx C, Effect Veiler, Nibiru) to break the opponent's first board, then rebuild through Cyberse searchers into a Link boss
• Recovery: Recycle the GY through Link-monster revival effects (Linguriboh, Splash Mage, G Golem Crystal Heart) and Mathmech GY Special Summons, then rebuild Link or Xyz boards from the remaining searchers
• After siding: No side deck is registered (0 cards), so there is no post-side plan. The deck cannot adapt between games in a best-of-3 match.

Why it scores here

The deck is a Cyberse-based Link and Ignister hybrid, not a pure Mathmech list: only 9 of 60 cards carry the exact Mathmech name (15% purity), and the engine leans on generic Cyberse searchers and 12 Link monsters. Consistency is the strongest part of the score: the 17-copy archetype core has about a 92% chance of at least one card in a 5-card opening hand, and 12 searchers give about 81% for at least one. Interaction is dense (12 hand traps, Ash Blossom and Infinite Impermanence at 3 copies each), which lifts going-second and end-board quality. Closing power depends on the 2300-3000 ATK Link bosses, and the Extra Deck is fully used at 15 cards. The score is held down by the absence of any recorded combo or tournament data, the absence of a side deck, and the lack of a Mathmech Synchro in the Extra Deck. The score is built from the deck as a system, not from averaging card scores, and archetype popularity did not earn points.

Dimension scores

How the score was computed

Strategy profile: Midrange primary, Stun secondary (not blended numerically); Midrange profile used for Structural. Structural ≈ 64, Going First ≈ 66, Going Second ≈ 70, Meta = provisional, Tournament Reliability ≈ 60. Modifiers: No side deck (-2); Mathmech engine incomplete (-2). Final formula: 0.80*Structural + 0.20*TournamentReliability + ContextModifiers (Meta provisional) = 0.80*63.8 + 0.20*60 - 4 = 59

Probability & combo summary

• Opening a starter: P(≥1) ≈ 0.92 · key two-card combo ≈ — · full-brick estimate ≈ 0.08 (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 (12 hand traps, Ash Blossom and Infinite Impermanence at 3 copies each)
• High core-access probability (about 92% for at least one core card in a 5-card opening hand)
• Broad searcher density (12 searcher-text cards) for consistent starts
• Strong Link-3 to Link-5 bosses with 2300 to 3000 ATK in the Extra Deck

Weaknesses

• Low exact archetype purity (15%); the list is mostly generic Cyberse and sub-archetype cards
• No side deck, so no adaptability across games
• Missing Mathmech Synchro route in the Extra Deck, weakening the named engine
• Many singletons (19) reduce redundancy for a Link-heavy engine

Critical choke points

• Cyberse Link-monster summon path: the 12 Link monsters depend on a small number of Cyberse starters and materials
• Single Synchro in the Extra Deck is a non-Mathmech Firewall card, so Mathmech Synchro lines are absent

Recommended changes

Evidence & confidence

• Verified: Legal in master-duel: main 45, extra 15, side 0; Crossout Designator Limited (1), Maxx C Limited (1), Droll and Lock Bird Semi-Limited (2), all within legal copies; Archetype purity 15% exact-name; archetype spread listed in composition; Extra Deck breakdown: 12 Link, 2 Xyz, 1 Synchro
• Inferred: Core access about 0.92 and searcher access about 0.81 from hypergeometric estimates; Hand-trap density gives about 0.86 going-second hit probability; Interaction and boss-closing reads from card text
• Provisional: Meta Power (null, no dated metagame sample); Matchup fit (D13) with no tournament link
• 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; going-first and going-second splits are Inferred Meta Power is Provisional without a dated metagame sample No side deck registered, so post-side behavior is unknown
