Mathmech Deck #762293 — Yu-Gi-Oh! Duel Links

Deck — Deck Power Evaluation

Final Contextual Deck Power: 60/100 (±7 · Confidence: Medium)

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

Legality

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

Identity & game plan

• Win condition: Mathmech Extra Deck board: Primathmech Laplacian (Xyz) and Geomathmech Final Sigma (Synchro, 3000 ATK, unaffected by non-Mathmech effects) backed by Geomathmech Magma and the link pieces.; Link and Synchro pressure from S-Force Justify, Decode Talker Heatsoul and Splash Mage, with Magma's destroy-on-battle as board control.
• Turn 1 (going first): Normal Summon Mathmech Diameter, Sigma or Nabla, chain the Cyberse tuner route into a Synchro or Xyz Summon for a board, and hold Effect Veiler for the opponent's first Main Phase.
• Turn 2 (going second): Hold Effect Veiler (3) and Kiteroid (2) to answer the opponent's first summon, then use Mathmech Diameter, Nabla or Equation from the GY to rebuild a board.
• Recovery: Recover from the GY: Diameter, Nabla and Equation special-summon from the GY, and Multiplication and Addition add board presence while the Extra Deck stays intact.
• After siding: Not applicable: Duel Links has no Side Deck (side_count 0).

Why it scores here

The deck reliably opens a functional starter: Diameter, Sigma and Nabla (9 copies across three tuner cards) give about a 95% chance of at least one in an opening 5-card hand (Inferred, hypergeometric). Its Extra Deck matches the archetype-standard list (Laplacian x3, Final Sigma x2, Magma, Justify, Splash Mage, Heatsoul) and uses all 9 slots, so conversion into a board is plausible, though no recorded boards exist to confirm the ceiling. Interaction and resilience come from three Effect Veiler and two Kiteroid, plus Mathmech GY recursion; this is strongest on the going-second 6-card hand (about 64% for at least one hand trap). The score reflects consistency, median output and interaction on the system as a whole; Mathmech's popularity and the tier-3 guide note did not earn points, and card scores were not averaged.

Dimension scores

How the score was computed

Strategy profile: Midrange. Structural ≈ 60.2, Going First ≈ 60, Going Second ≈ 62, Meta = provisional, Tournament Reliability ≈ 58. Modifiers: hand_trap_redundancy (3); off_archetype_dead_slots (-2); main_core_absent (-1). Final formula: 0.80*Structural + 0.20*TournamentReliability + ContextModifiers (Meta provisional, no dated sample)

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

• Three-copy Tuner starters give reliable T1 access (about 95% in opening 5)
• Extra Deck is fully used and matches the archetype-standard list (usage 100% for Final Sigma, Justify, Splash Mage, Heatsoul)
• Layered going-second interaction from Veiler and Kiteroid
• Mathmech GY recursion gives a second line after disruption

Weaknesses

• No recorded boards, so ceiling and median are text-only inference
• No searcher or draw text, so recovery depends on the board
• Three Book of Eclipse and a single Droplet are weak in the Mathmech engine
• No Side Deck in Duel Links, so no post-side plan

Critical choke points

• Tuner starters Diameter/Sigma/Nabla: the opening hand needs one of nine copies
• Extra Deck link pieces (Justify, Heatsoul, Splash Mage) must be summoned from a live board

Recommended changes

Evidence & confidence

• Verified: Legality: 22 main, 9 extra, 0 side, Legal; Limited Superfactorial at 1 copy and Semi-Limited Kiteroid at 2 are within limits; Extra Deck composition (Laplacian 3, Final Sigma 2, Magma 1, Justify 1, Splash Mage 1, Heatsoul 1); Archetype purity 61.3% exact name
• Observed: Usage stats show the Extra Deck core at 100% inclusion for Final Sigma, Justify, Splash Mage and Heatsoul
• Inferred: P(at least one starter in opening 5) about 0.95; Hand-trap odds on going second about 0.64; Combo ceiling and median from text only
• Provisional: Meta and matchup fit (D13), no dated meta sample; Tier-3 status from a single minibox guide note
• 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, going-second and matchup rates are unknown usage_statistics in_this_deck and copies_in_deck flags report Extra-Deck core cards (Final Sigma, Justify, Splash Mage, Heatsoul, Laplacian) as absent even though the cards array lists them, so the missing_core and core_present_pct fields are unreliable; the cards array was treated as the source of truth archetype_core_group p_open_at_least_one_hand5 = 1 is a proxy that does not reflect real starter access and was not used Meta Power is Provisional unless a dated metagame sample is supplied
