Mathmech Deck #759407 — Yu-Gi-Oh! Duel Links

Deck — Deck Power Evaluation

Final Contextual Deck Power: 58/100 (±7 · Confidence: Medium)

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

Legality

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

Identity & game plan

• Win condition: Extra Monster Zone boards led by Geomathmech Final Sigma (3000 ATK, doubled battle damage in the EMZ) and Geomathmech Magma (2500 ATK, destroys cards on battle); Tornado Dragon and Primathmech Laplacian as Xyz boards; Mathmech Division/Multiplication/Addition ATK manipulation for closing damage (Inferred from card text)
• Turn 1 (going first): Normal Summon a Level 4 Mathmech starter (Nabla, Diameter or Sigma) and use its Special Summon text to reach a Level 4 Cyberse and build a Synchro/Xyz/Link into the Extra Monster Zone (Inferred)
• Turn 2 (going second): Use Forbidden Droplet or Mathmech Superfactorial to answer the opponent's first board, then rebuild through Mathmech starters and the Extra Deck (Inferred)
• Recovery: Recur Level 4 Cyberse or Mathmech monsters from the GY with Diameter, Sigma, Equation and Superfactorial (Inferred from card text, no combo evidence)
• After siding: No side deck is registered (side_count 0), so there is no post-side plan; Duel Links is scored on the main deck only

Why it scores here

The deck reliably opens a Level 4 Cyberse starter: about 10 hand-starter copies in 24 main-deck cards give an estimated 0.95 chance of at least one in an opening 5-card hand (Inferred), and Nabla alone is 0.52 at 3 copies. Its interaction breadth (Forbidden Droplet, Superfactorial, Induction, Trunade, Splash/Justify text, Final Sigma's protection) and recursion routes support resilience, but the deck has no hand traps and no side deck. The conversion ceiling and median output are not measured because no recorded boards exist, so those scores rest on card-text reads and a single guide, and they stay near the middle. Structural strength comes from consistency and interaction on the system, not from Mathmech's popularity or the guide's tier claim, which earned no points, and card scores were not averaged.

Dimension scores

How the score was computed

Strategy profile: Combo. Structural ≈ 60.5, Going First ≈ 64, Going Second ≈ 60, Meta = provisional, Tournament Reliability ≈ 60. Modifiers: Banlist exposure (-1); Engine conflict (-2); Engine compactness (1). Final formula: 0.80*Structural + 0.20*TournamentReliability + ContextModifiers (-2); Meta provisional (null)

Probability & combo summary

• Opening a starter: P(≥1) ≈ 0.95 · 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 Level 4 Cyberse starter package with three-copy Nabla
• Interaction breadth without hand traps (Droplet, Superfactorial, Induction, Trunade, Tornado)
• Strong closing Extra Deck (Final Sigma, Magma, Justify) with battle-damage and destroy text

Weaknesses

• No side deck, so no post-side adaptation
• Several situational cards (Book of Eclipse x3, Droplet x2, Trunade x2) need specific opponent boards
• Off-theme Extra Deck slots (Exciton Knight) dilute the engine

Critical choke points

• Extra Monster Zone access for Final Sigma and Magma lines
• Single copy of Mathmech Superfactorial as the only Limited recursion/negation piece

Recommended changes

Evidence & confidence

• Verified: Legal main 24 / extra 9 / side 0 within size rules 20-30 / 0-9 / 0-9; Mathmech Superfactorial Limited, 1 copy (legal 1); Hey, Trunade! Semi-Limited, 2 copies (legal 2); Copy histogram 1:8, 2:5, 3:2; 15 distinct main-deck cards
• Observed: Usage stats: 9 of 19 core cards present; Mathmech core at 100% inclusion for Superfactorial, Addition, Equation; Exact-name archetype purity 57.6%
• Inferred: At least one hand starter in 5 cards ≈ 0.95; Nabla in 5 cards = 0.52 (hypergeometric); Recursion and interaction routes inferred from card text; Engine conflict from off-theme Extra Deck slots
• Provisional: Meta power unavailable: no dated metagame sample; Matchup fit unknown; guide's tier-3 claim unverified; Going-first and going-second splits unmeasured
• Data gaps: No combos supplied: floor, median, ceiling and board-per-starter are text-only inference No tournament link: archetype meta-share and per-pilot records absent No side deck: post-side and matchup adaptability unmeasured usage_statistics in_this_deck flags conflict with the cards list for extra-deck cards (Splash Mage, S-Force Justify, Decode Talker, Final Sigma, Magma), so the 'missing_core' list is unreliable Only one guide, and its tier claim is not verified No win-rate telemetry for going-first, going-second, matchups or brick rates
