Identity & game plan

Win condition: Mathmech Extra Deck board (Primathmech Laplacian x2, Geomathmech Final Sigma) backed by Link and Synchro pressure from Borreload Savage Dragon, S-Force Justify and Topologic Trisbaena; Level-4 Cyberse attack stacking through Mathmech Multiplication, Addition and Division, with Mathmech Billionblade Nayuta adding ATK in battle
Turn 1 (going first): Open on a Level-4 Mathmech starter (Nabla, Diameter or Sigma) to reach Extra Deck summons, keeping Droll & Lock Bird and Artifact Lancea in hand as first-turn answers
Turn 2 (going second): Hold hand traps (Droll & Lock Bird x2, Artifact Lancea x2, Forbidden Droplet x3) to answer the opponent's first board, then rebuild with Mathmech summons
Recovery: Recycle Mathmech monsters from the GY with Mathmech Nabla, Diameter, Equation and Billionblade Nayuta, and use Mathmech Superfactorial as a single-copy Synchro reboot
After siding: None: Duel Links has no sideboard in play, and the deck registers 0 side cards

Why it scores here

The deck reliably opens on a Level-4 Mathmech starter: Nabla, Diameter and Sigma together give roughly an 0.89 chance of at least one in a 5-card opening hand (hypergeometric, Inferred), which makes the Extra Deck engine live on turn 1 or 2 in most games. Its interaction package (Droll & Lock Bird, Artifact Lancea, Forbidden Droplet, Mathmech Induction, Superfactorial, S-Force Justify) gives a strong going-second hand, with roughly a 0.75 chance of at least one hand trap in a 6-card hand. Closing power comes from 2000-3000 ATK Extra Deck monsters, with Final Sigma's doubled battle damage as the finisher. The score comes from consistency, interaction and closing on the system, not from averaging card scores or from the archetype's guide-stated Tier 3 status, which only confirms that the list is playable. No combo boards were recorded, so ceiling and median are text-based estimates. The score is capped by an off-archetype Extra Deck filler package, single-copy Limited Superfactorial as a choke point, and no sideboard.

Dimension scores

#	Dimension	Score	Evidence
D1	Engine Accessibility & Consistency	70	P(at least one of Nabla/Diameter/Sigma in 5-card opening hand) ≈ 0.89; single-copy Nabla alone ≈ 0.56 (Inferred)
D2	Opening-Hand Quality & Brick Management	62	14 distinct main cards with 8 singletons; 3 hand traps and 3 Droplets are dead without a board, but the Level-4 Cyberse base keeps most hands functional (Inferred)
D3	Combo Conversion & Ceiling	58	Laplacian Xyz, Final Sigma and Superfactorial Synchro lines exist in card text, but no recorded boards are supplied (Inferred)
D4	Combo Floor & Median Output	52	No power distribution or median board data; floor and median are not measured and sit near the midpoint (Provisional)
D5	Interruption Resilience & Route Redundancy	66	Redundant Level-4 starters (Nabla, Diameter, Sigma, Subtraction, Addition, Multiplication, Division) give several independent routes after a single hand trap (Inferred)
D6	Resource Economy, Recovery & Grind	62	Recursion from GY via Nabla, Diameter, Equation and Nayuta, plus Subtraction and Addition searches, gives moderate recovery; no resource signature data (Inferred)
D7	End-Board & Interaction Quality	68	Interaction density from text: 6 negation, 5 removal and 4 hand-trap cards, including Induction and Justify's negate-and-move effect (Inferred from card text)
D8	Going-Second & Board-Breaking Power	68	Going-second hand-trap density (≈0.75 for at least one hand trap in 6) plus Droplet's mass negation covers the first board well (Inferred)
D9	Offensive Pressure & Closing Power	70	Extra Deck attackers at 2000-3000 ATK, Final Sigma's doubled battle damage, and Borreload/Justify pressure (Verified stats, Inferred closing)
D10	Main Deck Efficiency & Flexibility	58	22-card main at the Duel Links minimum of 20 with 58.1% exact-name purity; 6 generic or other-archetype cards dilute the engine (Verified composition, Inferred efficiency)
D11	Extra Deck Efficiency & Coverage	55	Two Laplacian Xyz slots need three Level-4 materials, while 4-5 of the 9 Extra slots are generic link or other-archetype fillers (Verified composition, Inferred)
D12	Side Deck Adaptability	35	Duel Links has no sideboard in play and the deck registers 0 side cards, so this dimension is not applicable and is scored low and held outside the central read (Verified format rule)
D13	Matchup Coverage & Format Fit	52	Archetype core present 47.4% of usage stats and guide-stated Tier 3 status; no tournament data or dated meta sample (Provisional)
D14	Pilotability & Error Tolerance	58	Multi-step Extra Deck summon chains with Level changes, Tribute conditions and once-per-turn limits give a moderate decision load (Inferred)

How the score was computed

Strategy profile: Midrange. Structural ≈ 61.5, Going First ≈ 63, Going Second ≈ 67, Meta = provisional, Tournament Reliability ≈ 60. Modifiers: Single-copy Limited engine card (-2); Off-archetype Extra Deck fillers (-2). Final formula: 0.80*Structural + 0.20*TournamentReliability + ContextModifiers (Meta provisional) = 0.80*61.5 + 0.20*60 - 4 ≈ 57

Probability & combo summary

Opening a starter: P(≥1) ≈ 0.89 · 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

Redundant Level-4 Cyberse starters with GY recursion
Hand-trap and negation density strong for going second
Strong closers: Final Sigma, Borreload, Justify, Laplacian

Weaknesses

Off-archetype Extra Deck fillers dilute Mathmech engine
Single-copy Limited Superfactorial as a synchro choke
No sideboard, so no post-side adaptation
Non-engine tech (Droplet x3, Droll x2) dead without a board

Critical choke points

Mathmech Superfactorial (single Limited copy) is the only Synchro reboot
Level-4 Cyberse starter count (7) for Laplacian Xyz materials

Recommended changes

Priority	Remove	Add	Reason
1	Topologic Trisbaena	a second Mathmech Synchro or Xyz route card (if available in the format)	Reduces off-archetype Extra Deck dependence; the Trisbaena effect does not line up with the Mathmech board
2	Forbidden Droplet (one copy)	a Level-4 Mathmech starter	Increases engine access on going first; the Droplet copy is a dead card on a bare board

Evidence & confidence

Verified: Legal status and 22/9/0 counts within Duel Links size rules; Mathmech Superfactorial Limited, 1 copy run of 1 allowed; Archetype purity 58.1% exact name; Usage stats: Mathmech core present in 47.4% of archetype core cards
Observed: Guide states Mathmech is Tier 3 in the latest mini-box (guide text, single source)
Inferred: At least one starter in 5-card opening hand ≈ 0.89; Hand-trap odds on going second ≈ 0.75; Interaction density from card-text read; Extra Deck engine liveness from card text
Provisional: Meta Power (no dated metagame sample); Matchup and format fit; Side-deck performance (not applicable 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: going-first/second, matchup and brick rates are Inferred or Unknown Meta Power is Provisional unless a dated metagame sample is supplied no sideboard in Duel Links: D12 has no post-side performance data
