Mathmech Deck #750854 — Yu-Gi-Oh! Duel Links

Deck — Deck Power Evaluation

Final Contextual Deck Power: 64/100 (±8 · Confidence: Medium)

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

Legality

Main 30 / Extra 9 / Side 0 — status: Legal.

Identity & game plan

• Win condition: Chain Mathmech Cyberse monsters into Synchro/Xyz/Link summons (Geomathmech Final Sigma x2, Primathmech Laplacian x2, Splash Mage, Decode Talker Heatsoul, S-Force Justify) and close with 3000-ATK and 2600-ATK bosses.; Ghost Belle and Mathmech recursion from the GY grinds back into the Extra Deck once the opening starter is interrupted.
• Turn 1 (going first): Normal Summon a Mathmech Level-4 Cyberse or Tuner, extend through Mathmech Addition / Multiplication / Division, then Synchro or Xyz into a boss while Mathmech Induction and Superfactorial hold the board.
• Turn 2 (going second): Use Artifact Lancea and Ghost Belle as hand traps against the opponent's first play, then rebuild a Mathmech board from the GY or with Forbidden Droplet and Book of Eclipse to break their board.
• Recovery: Mathmech Equation and Mathmech Division special summon from the GY, Cynet Mining searches a Level-4 or lower Cyberse, and Ghost Belle banishes or recurs GY cards.
• After siding: No side deck is run (side 0), so there is no post-side plan; Duel Links does not use a sideboard.

Why it scores here

The deck reliably opens a Mathmech board: the probability that at least one of the 16 archetype-core cards is in a 5-card opening hand is about 0.99, and three copies each of Mathmech Diameter, Sigma and Nabla give several independent Level-4 starters (Inferred). Its interaction package (nine negation-text cards, Superfactorial, Ghost Belle, Artifact Lancea and three Forbidden Droplet) lets it contest the opponent's board, and its Extra Deck of 2600-3000 ATK bosses supplies closing power. No combo boards were recorded, so the ceiling and median scores rest on structural text reads and are not measured outcomes. Guide claims that the archetype is tier 3 and cheap to play are reported as provisional, and no tournament or win-rate data were used. The score was produced from consistency, interaction and resilience on the deck as a system, not from averaging card scores or from the archetype's popularity.

Dimension scores

How the score was computed

Strategy profile: Combo. Structural ≈ 64.7, Going First ≈ 68, Going Second ≈ 62, Meta = provisional, Tournament Reliability ≈ 60. Modifiers: banlist exposure (0); no combo evidence (0). Final formula: 0.80*Structural + 0.20*TournamentReliability (Meta provisional) = 0.80*64.7 + 0.20*60 = 63.8, rounded to 64

Probability & combo summary

• Opening a starter: P(≥1) ≈ 0.99 · key two-card combo ≈ — · full-brick estimate ≈ 0.01 (all Inferred)
• Combo output: best PowerIndex —, median —, board-per-starter —
• Turn order: 0 going-first lines vs 0 going-second lines

Strengths

• Starter density: 16 archetype-core cards with three copies of each Level-4 Tuner starter
• Layered interaction from negation-text cards, Superfactorial, Ghost Belle and Forbidden Droplet
• Full Extra Deck (9 cards) of Synchro, Xyz and Link payoffs with 3000 and 2600 ATK bosses
• Legal list: the only restricted card, Superfactorial, is run at its limit of 1

Weaknesses

• No recorded combos, so ceiling and median are inferred from text rather than measured
• Off-archetype slots (20 of 39 non-zero copies, purity 48.7%) dilute engine coherence
• No side deck, so the deck cannot adapt after disruption
• Forbidden Droplet and Book of Eclipse are costly in some hands and do not advance the engine

Critical choke points

• Mathmech starters sit at 3 copies each, so an opening hand with none of the three Level-4 Tuners falls back to the 1-copy extenders
• Cynet Mining (2 copies) is the only searcher, so recovery depends on GY recursion

Recommended changes

Evidence & confidence

• Verified: Deck is legal: 30 Main, 9 Extra, 0 Side under the Duel Links size rules; Mathmech Superfactorial is Limited with 1 copy run (legal limit 1); Archetype-core count is 16 and Mathmech purity is 48.7%; Usage statistics show 8 of 19 core cards present in the main deck (the Extra Deck is not counted; see data gaps)
• Inferred: P(>=1 core card in opening 5) = 0.986; Structural starter access is high on going first and second; Interaction and recursion layers add resilience; Board-breaking and closing power from text reads
• Provisional: Meta Power is null: no dated metagame sample; Tier-3 claim is taken from a single Vietnamese guide snippet, not from a verified meta source; Going-second split and matchup fit are unmeasured
• 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/second, matchup, brick/starter rates) Meta Power is provisional: no dated metagame sample usage_statistics data bug: Laplacian, Geomathmech Final Sigma, Splash Mage, Decode Talker Heatsoul and S-Force Justify are present in the Extra Deck cards list but reported as in_this_deck=false (only main-deck cards were matched), so core_present_pct 42.1 is understated (~68% when Extra Deck cards are counted) Guide snippet is a single Vietnamese post with no section structure
