Main 55 / Extra 15 / Side 0 — status: Illegal. 1 violation(s).

Identity & game plan

  • Win condition: Mathmech/Cyber Link-and-Synchro board built from hand-trap-supported starters, closing with Link-4/5 and Synchro boards (structural read only; no recorded combos); Archetype-core Mathmech Synchro/Xyz via Mathmech Sigma, Mathmech Circular, and Primathmech Laplacian/Alembertian
  • Turn 1 (going first): Open a Cyberse/Mathmech starter, use searchers (Pikari, Backup, Cynet Mining, A.I. Connect) to find the next link, and hold hand traps (Ash Blossom, Infinite Impermanence, Evenly Matched) for the opponent's first interaction
  • Turn 2 (going second): Use the six-card hand to deploy hand traps against the opponent's first summon or activation, then rebuild from the Extra Deck link chain
  • Recovery: Recover via Mulcharmy Fuwalos/Purulia draws and Cynet/A.I. searchers after hand traps are spent; Mathmech Superfactorial can revive Mathmech monsters from the GY
  • After siding: Not evaluable: the deck has no side deck (0 cards); the side plan is absent

Why it scores here

The deck's structural read is an Interaction-heavy Stun shell (19 hand-trap copies, Solemn and Evenly Matched style traps) wrapped around a Cyberse/Mathmech link engine with 10 Link monsters in the Extra Deck. Archetype purity is low (11.4% exact-name Mathmech, 62 off-archetype copies), so the engine depends on cross-archetype Cyberse searchers rather than a single coherent core. The deck has no recorded boards, so every conversion and floor score is an Inferred text-only read rather than a measured output. Popularity or archetype share earned no points, and card scores were not averaged into the deck score. The list is Illegal (Ash Blossom at 3 copies in an OCG Semi-Limited slot), so the final score is capped low and the evaluation is theoretical/structural only.

Dimension scores

# Dimension Score Evidence
D1 Engine Accessibility & Consistency 55 P(≥1 archetype-core copy in opening hand of 5) ≈ 0.81 across 15 core copies; but only 8 exact-name Mathmech copies and 11.4% purity (Inferred)
D2 Opening-Hand Quality & Brick Management 45 19 hand-trap copies plus 11 searcher-text copies imply frequent non-engine hands; P(≥1 hand trap in 6) ≈ 0.93 (Inferred)
D3 Combo Conversion & Ceiling 40 No parseable boards, so no measured ceiling; text-only link-chain read suggests moderate Link-4/5 conversion (Inferred)
D4 Combo Floor & Median Output 35 No combo data, so the median and floor are unmeasured; the card-text read suggests a floor near a single starter plus searchers (Inferred)
D5 Interruption Resilience & Route Redundancy 58 Multiple independent interaction and searcher routes (Ash, Impermanence, Veiler, Cynet, A.I. Connect) support some recovery after one disruption (Inferred)
D6 Resource Economy, Recovery & Grind 45 Searchers and Mulcharmy draw effects offset spend, but the resource loop is not measured (Inferred)
D7 End-Board & Interaction Quality 65 Hand traps and Solemn-style traps give broad, layered interaction (19 hand traps, 17 negation-text copies) (Inferred from card text)
D8 Going-Second & Board-Breaking Power 60 Hand traps and Droll & Lock Bird give strong going-second interaction; no going-second board data (Inferred)
D9 Offensive Pressure & Closing Power 50 Link-4/5 finishers (Firewall Dragon Darkfluid, Accesscode Talker) are present, but Synchro/XYZ count is only 2 each and the boards are unmeasured (Inferred)
D10 Main Deck Efficiency & Flexibility 50 55 Main cards, 33 distinct, 20 singletons; the 19 hand-trap copies dilute the engine slots (Verified structure, Inferred interpretation)
D11 Extra Deck Efficiency & Coverage 55 15/15 Extra slots used; 10 Link monsters; mostly flexible Link routes, but several Extra cards have no in-deck archetype support (Verified counts)
D12 Side Deck Adaptability 5 No side deck (0 of 15 slots); no post-side plan can be evaluated (Verified)
D13 Matchup Coverage & Format Fit 40 No tournament link and no dated metagame sample; the archetype share is not evidence of matchup fit (Provisional)
D14 Pilotability & Error Tolerance 45 Multiple decision points: hand-trap timing, Link route selection, and searcher ordering across several effects (Inferred)

How the score was computed

Strategy profile: Stun. Structural ≈ 48, Going First ≈ 42, Going Second ≈ 52, Meta = provisional, Tournament Reliability ≈ 40. Modifiers: Banlist exposure (-10); Illegal cap (-11). Final formula: Structural (Stun profile, D13 dropped and re-normalized) = 48; Final = 0.80*48 + 0.20*40 = 46.4; modifiers -10 (banlist exposure) = 36.4; capped to 25 because the list is Illegal (theoretical/structural only)

Probability & combo summary

  • Opening a starter: P(≥1) ≈ 0.81 · 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

  • Dense hand-trap suite (19 copies) with strong going-second interaction
  • Searcher density (11 copies) keeps the link chain reachable
  • Link-heavy Extra Deck with 10 Link monsters gives flexible routes

Weaknesses

  • Illegal copy-limit violation on Ash Blossom & Joyous Spring
  • Low archetype purity (11.4% exact-name) splits engine coherence across Ignister, Code Talker, Mulcharmy, and Cyber
  • No side deck, so no post-side plan
  • Several Extra Deck cards have no in-deck archetype support

Critical choke points

  • Legality: the list cannot be played as built until the Ash Blossom copy count is fixed
  • Engine start depends on Mathmech/Cyber searchers (Cynet Mining, A.I. Connect) that are single-copy or low-count
Priority Remove Add Reason
1 1 copy of Ash Blossom & Joyous Spring A legal non-duplicate hand trap or a second engine card Restores legality; the deck cannot be scored as played until the copy limit is fixed
2 None A 15-card side deck The deck has no side deck, so D12 scores near zero and post-side play is unevaluated

Evidence & confidence

  • Verified: Main 55, Extra 15, Side 0 are within OCG size rules; Ash Blossom & Joyous Spring runs 3 copies against a Semi-Limited limit of 2; Five Limited cards run 1 copy each (legal); Archetype purity is 11.4% exact-name; 62 off-archetype copies
  • Inferred: Starter and hand-trap probabilities (hypergeometric); Stun-profile structural read; Interaction and resilience scoring from card text
  • Provisional: Meta and matchup fit (no dated metagame sample)
  • Data gaps: No combos supplied, so combo floor, median, and ceiling are text-only inference No tournament link; archetype meta-share and per-pilot records are absent No side deck, so no post-side evidence No win-rate telemetry for OCG (going-first/second, matchup, brick rates) in YGOVN Meta Power is Provisional unless a dated metagame sample is supplied
