Mathmech Deck #751697 — Yu-Gi-Oh! Duel Links

Deck — Deck Power Evaluation

Final Contextual Deck Power: 67/100 (±6 · Confidence: Medium)

• Primary strategy: Midrange
• Secondary strategies: Stun
• Format: duel-links

Legality

Main 22 / Extra 9 / Side 0 — status: Legal.

Identity & game plan

• Win condition: Extra Deck Synchro/Link/Xyz boss pressure, led by Geomathmech Final Sigma (3000 ATK, doubled battle damage in the Extra Monster Zone) and Geomathmech Magma (2500 ATK, destroys cards on battle); Link-3 and Link-2 Cyberse beaters (S-Force Justify, Decode Talker Heatsoul, Splash Mage) that stack on the same Extra Monster Zone board
• Turn 1 (going first): Normal Summon Mathmech Diameter, Sigma or Nabla to reach Level 4 Cyberse monsters, then Synchro, Xyz or Link into the Extra Deck boss while Mathmech Induction or Equation adds pressure
• Turn 2 (going second): Use Effect Veiler or Forbidden Droplet to negate the opponent's engine monster or board, then rebuild with the Level 4 Cyberse starters and Extra Deck boss
• Recovery: Recurse from the GY with Diameter (revive a Level 4 Cyberse), Splash Mage (revive as a negated Link), and Mathmech Superfactorial (Synchro Summon from GY), then rebuild the Extra Monster Zone board
• After siding: Not applicable: Duel Links has no side deck (side_count 0)

Why it scores here

The deck reliably opens a functional Mathmech engine: 9 copies of the three Level 4 Cyberse starters (Diameter, Sigma, Nabla) give about a 95% chance of at least one in a 5-card opening hand (hypergeometric, Inferred) and about 71% for at least two. Its interaction is layered, with three Effect Veiler and three Forbidden Droplet plus Mathmech Induction, Superfactorial and the Extra Deck link negation, which supports the going-second plan. Conversion into pressure is strong on paper through the Extra Deck boss and recursion, but no recorded boards exist, so combo ceiling and median are text-only inferences and are scored conservatively. The score comes from consistency, recursion, and interaction on the system as a whole, not from Mathmech being a popular archetype (usage stats and the guide only confirm it is real and accessible) and not from averaging card scores. Meta and matchup fit stay provisional because no tournament or dated metagame sample is linked.

Dimension scores

How the score was computed

Strategy profile: Midrange. Structural ≈ 68, Going First ≈ 70, Going Second ≈ 68, Meta = provisional, Tournament Reliability ≈ 66. Modifiers: Limited key card (Mathmech Superfactorial) (-2); Engine compactness (Cyberse-dense) (2). Final formula: 0.80*Structural + 0.20*TournamentReliability (Meta provisional); Structural 67.9 and TR 66 before modifiers, net modifiers 0

Probability & combo summary

• Opening a starter: P(≥1) ≈ 0.95 · key two-card combo ≈ 0.71 · full-brick estimate ≈ 0.05 (all Inferred)
• Combo output: best PowerIndex —, median —, board-per-starter —
• Turn order: 0 going-first lines vs 0 going-second lines

Strengths

• Nine Level 4 starter copies over three cards give high opening-hand access
• Layered negation: Veiler, Droplet, Superfactorial, Justify and Splash Mage
• Three recursion routes keep the engine alive after an interruption
• Extra Deck boss (Final Sigma) gives a clear closing threat
• Compact and coherent: 21 of 22 Main Deck cards are Cyberse

Weaknesses

• No recorded boards, so ceiling and median are unmeasured
• Usage stats do not join Extra Deck cards to the deck (see data gaps), so core coverage is understated
• Single-copy Superfactorial is a dependency on a Limited card
• Several one-of utility cards dilute consistency
• Going-first hand with no Level 4 starter and no hand trap is a dead-hand risk

Critical choke points

• Mathmech Superfactorial (Limited, 1 copy) for GY-to-Synchro revive
• Level 4 Cyberse starters (9 copies) as the only route into the Extra Deck

Recommended changes

Evidence & confidence

• Verified: Legal status, copy counts and size (22 Main, 9 Extra, 0 Side); Card text and banlist status (Superfactorial Limited, 1 copy); Archetype usage and guide snippet exist
• Inferred: P(at least one starter in opening hand) 0.95 going first; Hand-trap and recursion consistency; Ceiling and median read from text only; Interaction density from regex text hints
• Provisional: Meta Power (no dated metagame sample); Matchup and format fit (no tournament link); Side deck adaptability (no side deck in Duel Links)
• 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 exists in YGOVN, so going-first, going-second and matchup splits are Inferred usage_statistics does not match Extra Deck cards: Geomathmech Final Sigma, Primathmech Laplacian, Geomathmech Magma and S-Force Justify are in the deck (zone extra) but marked in_this_deck false, and their core_cards_present and missing_core values are unreliable Kiteroid (ref -1) is unresolved in usage_statistics Meta Power is Provisional unless a dated metagame sample is supplied
