Legality
Main 26 / Extra 9 / Side 0 — status: Legal.
Identity & game plan
- Win condition: Mathmech Tuner starters (Nabla, Diameter, Sigma) chain into Geomathmech Final Sigma and other Synchro, Xyz and Link boards for lethal pressure (Inferred; no recorded boards); Link and Xyz boards (S-Force Justify, Decode Talker Heatsoul, Tornado Dragon, Evilswarm Exciton Knight) with ATK boosts from Mathmech Addition, Multiplication and Equation
- Turn 1 (going first): Open with a Cyberse Tuner (Nabla or Diameter or Sigma) and use Nabla's Tribute effect or Sigma's hand Special Summon to reach a Mathmech and a Synchro or Xyz (Inferred from card text)
- Turn 2 (going second): Use Book of Eclipse, Forbidden Droplet, Ghost Ogre and Snow Rabbit to answer the opponent's board, then rebuild from the GY with Mathmech Equation and Sigma (Inferred from card text)
- Recovery: Mathmech Equation revives a Mathmech from the GY with +1000 ATK; Multiplication and Division have GY effects; Billionblade Nayuta sends a Mathmech from Deck to GY for ATK (Inferred from card text)
- After siding: None: the side deck is empty (0 cards) and the evidence has no post-side data
Why it scores here
The deck reliably opens a Mathmech card: the archetype core of 15 main-deck copies gives P(at least one in a 5-card opening hand) of about 0.99, and Nabla alone is about 0.49 going first (Inferred, hypergeometric). Its engine is Cyberse Tuner chaining, so it converts into a strong closing board: Final Sigma (3000 ATK), Justify (2600), Heatsoul (2300) and Tornado Dragon are real pressure cards. Interaction is layered across hand traps, negations, Book of Eclipse, Induction and Exciton, which earns the endboard score. Recovery through Equation, Multiplication and Nayuta is present but unrecorded, and there are no recorded boards, so the median and ceiling are text-based inference. The score comes from consistency, median-to-ceiling output and interaction on the system as a whole. It is not a card-by-card average, and Mathmech's popularity earned no points beyond the usage-based core check.
Dimension scores
| # | Dimension | Score | Evidence |
|---|---|---|---|
| D1 | Engine Accessibility & Consistency | 66 | P(>=1 Nabla in 5) = 0.49 and archetype core P(>=1 in 5) = 0.993; Sigma's hand Special Summon is conditional on an empty EMZ (Inferred) |
| D2 | Opening-Hand Quality & Brick Management | 62 | 15 of 26 main cards are Mathmech, so bricks are low, but 2 Trunade, 2 Droplet and the Limited Superfactorial are dead or late in many hands (Inferred) |
| D3 | Combo Conversion & Ceiling | 62 | No recorded boards; ceiling inferred from Final Sigma double damage, Magma destroying up to 2 on battle, and Justify/Heatsoul links (Inferred from text) |
| D4 | Combo Floor & Median Output | 50 | No recorded boards, so the median is unknown and set near the middle of the range (Provisional) |
| D5 | Interruption Resilience & Route Redundancy | 58 | Three Tuner starters and Equation recursion give redundancy, but most lines run through Nabla or Sigma (Inferred) |
| D6 | Resource Economy, Recovery & Grind | 66 | Equation, Multiplication, Division and Nayuta recur Mathmech from the GY; no resource or net-advantage data (Inferred from text) |
| D7 | End-Board & Interaction Quality | 70 | Negation text on 5 cards and removal text on 4 (Droplet, Ghost Ogre, Induction, Tornado, Justify, Exciton) give broad, layered interaction (Inferred from text and role tags) |
| D8 | Going-Second & Board-Breaking Power | 62 | Droplet and Book of Eclipse can flip or shrink opposing effect monsters, and Ghost Ogre is a single hand trap; no going-second split exists (Inferred) |
| D9 | Offensive Pressure & Closing Power | 72 | Final Sigma 3000, Justify 2600, Heatsoul 2300 and Tornado 2100 give closing power; double battle damage on Final Sigma adds reach (Verified stats, Inferred use) |
| D10 | Main Deck Efficiency & Flexibility | 60 | 26 main cards with 17 distinct names, 16 of 26 Mathmech/tech-coherent, legal size; 10 singles add variance (Verified counts, Inferred coherence) |
| D11 | Extra Deck Efficiency & Coverage | 70 | All 9 Extra slots are used across 3 Synchro, 3 Xyz and 3 Link monsters, and the Mathmech Synchro and Xyz core is covered (Verified composition) |
| D12 | Side Deck Adaptability | 30 | Side deck is empty, so there is no post-side adaptation; Duel Links post-side data is not supplied (Provisional) |
| D13 | Matchup Coverage & Format Fit | 50 | No tournament link or dated meta sample; the guide's tier 3 claim is community context only (Provisional) |
| D14 | Pilotability & Error Tolerance | 52 | Multi-step Tribute, Special Summon and restriction chains with many decision points, moderate complexity (Inferred from text) |
How the score was computed
Strategy profile: 70/30. Structural ≈ 61.3, Going First ≈ 64, Going Second ≈ 62, Meta = provisional, Tournament Reliability ≈ 56. Modifiers: No side deck (-2). Final formula: 0.80*Structural(61.3) + 0.20*TournamentReliability(56) + modifiers(-2) = 58.2, rounded to 58 (Meta provisional)
Probability & combo summary
- Opening a starter: P(≥1) ≈ 0.49 · 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
- Archetype core is almost always present in the opening hand (P = 0.993)
- Layered interaction across hand traps, negations, mass flip and removal
- Recursion from the GY (Equation, Multiplication, Division, Nayuta)
- Strong closing Extra Deck with 9 Extra slots fully used
- Restricted cards are legal: Superfactorial 1/1 Limited, Trunade 2/2 Semi-Limited
Weaknesses
- No side deck, so no post-side adaptation
- No recorded boards, so median and ceiling are inferred from text
- Off-archetype main-deck slots (Droplet, Trunade, Book of Eclipse, Ghost Ogre) add variance
- Superfactorial needs three Mathmech in the GY, so it is late-game only
Critical choke points
- Tuner starters Nabla, Diameter and Sigma: most lines depend on one of them
- Empty EMZ requirement for Sigma's hand Special Summon
Recommended changes
| Priority | Remove | Add | Reason |
|---|---|---|---|
| 1 | Hey, Trunade! (1 copy) | A second Mathmech Multiplication or Mathmech Addition (Mathmech cards already in the archetype pool) | Trunade is a non-archetype card that is often dead in opening hands; a second Mathmech card raises starter density (Inferred) |
| 2 | None | None | Verify the usage_statistics in_this_deck flags before changing the Extra Deck: they report Final Sigma, Laplacian, Magma, Justify, Heatsoul and Splash Mage as absent even though the cards list includes them |
Evidence & confidence
- Verified: Legality: 26 Main, 9 Extra, 0 Side; Legal under BanDuelLink; Restricted cards: Superfactorial 1 of 1 (Limited), Hey, Trunade! 2 of 2 (Semi-Limited); Composition and copy counts match the cards list; Hypergeometric draw probabilities (5-card and 6-card hands)
- Inferred: Opening-hand starter reliability (Nabla 0.49, archetype core 0.993); Brick and dead-card risk from off-archetype main slots; Interaction density from negation and removal text tags; Closing power from Extra Deck ATK; Recursion and resource text
- Provisional: Meta power (null: no dated sample); Matchup and format fit; Side deck adaptability (empty side)
- Data gaps: No combos supplied: floor, median and ceiling are text-only inference No tournament link: archetype meta-share and per-pilot record absent No win-rate telemetry (going first or second, matchup, brick or starter rates) Meta power is provisional unless a dated metagame sample is supplied Side deck is empty: no post-side data usage_statistics in_this_deck flags conflict with the cards list for Final Sigma, Laplacian, Magma, Justify, Heatsoul and Splash Mage; the cards list was used
