Mathmech Deck #774400 — Yu-Gi-Oh! Duel Links

Deck — Deck Power Evaluation

Final Contextual Deck Power: 57/100 (±6 · Confidence: Medium)

• Primary strategy: Combo
• Secondary strategies: Midrange, Tempo
• Format: duel-links

Legality

Main 24 / Extra 9 / Side 0 — status: Legal.

Identity & game plan

• Win condition: Extra Deck boss monsters (Geomathmech Final Sigma, Primathmech Laplacian, S-Force Justify, Topologic Trisbaena) reached through Mathmech Tuner-based Synchro/Xyz/Link chains.; Mathmech Superfactorial Synchro line from GY monsters, plus direct damage from Final Sigma's doubled battle damage.
• Turn 1 (going first): Normal Summon Mathmech Diameter or Sigma (Tuner) to reach a Level 4 Cyberse Synchro or Xyz base, then Synchro/Xyz into a boss. Mathmech Addition and Equation are the single-copy extenders.
• Turn 2 (going second): Hold Infinite Impermanence or Artifact Lancea (Hand Trap) and Forbidden Droplet to answer the opponent's first board, then rebuild through Mathmech Nabla/Multiplication recursion from the GY.
• Recovery: Recover from the GY: Mathmech Nabla and Multiplication are GY-triggered (extra attacks, Level changes), and Mathmech Equation revives a GY Mathmech monster.
• After siding: Not applicable: Duel Links has no Side Deck in play (Side Deck size 0), so no post-side plan exists.

Why it scores here

The deck opens reliably through its three 3-copy starters (Diameter, Sigma, Book of Eclipse), with a 52% chance of at least one in a 5-card opening hand (Inferred). Its Extra Deck covers Synchro, Xyz, and Link bosses with 9 of 9 slots used, and the 3 Hand Traps (Impermanence x2, Lancea) and Forbidden Droplet give it a real answer to the opponent's first board. The score comes from consistency, interaction, and extra-deck coverage on the system, not from averaging the cards' individual strength. Archetype popularity (one minibox Tier 3 mention) earned no points, and the score is capped by the absence of recorded combo boards and any tournament or meta data.

Dimension scores

How the score was computed

Strategy profile: Combo. Structural ≈ 60, Going First ≈ 58, Going Second ≈ 56, Meta = provisional, Tournament Reliability ≈ 55. Modifiers: banlist exposure (-2). Final formula: 0.80*Structural + 0.20*TournamentReliability (Meta provisional)

Probability & combo summary

• Opening a starter: P(≥1) ≈ 0.52 · 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

• Three 3-copy starters give the most reliable opening
• Full Extra Deck covering Synchro, Xyz, and Link bosses
• Hand Traps and Forbidden Droplet give a real answer to the first board

Weaknesses

• No recorded combo boards, so floor and median are unmeasured
• Single-copy Mathmech spells add brick risk
• Off-archetype copies (15) dilute the engine

Critical choke points

• Dependence on a Tuner in hand or GY to start Synchro lines
• Mathmech Superfactorial (Limited, 1 copy) is a single-card dependency

Recommended changes

Evidence & confidence

• Verified: Legal status, 24/9 size, Limited Superfactorial at 1 copy; Card stats and text for all 22 distinct cards; Hypergeometric starter odds
• Inferred: Consistency and brick estimates; Interaction and resilience reads from card text; Going-first and going-second split
• Provisional: Meta and format fit (no tournament or dated meta sample); Side plan (not applicable in Duel Links)
• 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 win-rate telemetry exists in YGOVN (going-first/second, matchup, game-level, brick/starter/OTK rates) — those signals are Inferred or Unknown Meta Power is Provisional unless a dated metagame sample is supplied
