Legality

Main 45 / Extra 15 / Side 0 — status: Legal.

Identity & game plan

  • Win condition: Maintain board control with hand traps and negation, then finish with high‑ATK Cyberse links.; Conditional OTK via Mathmech Synchro/XYZ combos when key pieces are assembled.
  • Turn 1 (going first): Activate hand traps, search Mathmech core with Cyberse searchers, establish a Link or Xyz monster.
  • Turn 2 (going second): Use hand‑trap draw engines to disrupt opponent, then summon Mathmech board using extra‑deck links.
  • Recovery: Leverage Mulcharmy draw effects, Droll & Lock Bird, Maxx "C", and Cyberse recursion to rebuild after disruption.
  • After siding: Swap extra‑deck links (Accesscode Talker, Allied Code Talker, Firewall Dragon) to adapt to opponent's board after side‑decking.

Why it scores here

The deck reliably opens with at least one core Mathmech or Ignister card (>92% chance), giving a solid starter. Hand traps and numerous negation cards provide strong interaction and resilience to disruption. Draw engines (Mulcharmy, Droll & Lock Bird, Maxx "C") supply resource recovery, while a full 15‑card extra deck offers multiple finishing routes. However, low archetype purity and the absence of a side deck lower efficiency and adaptability, keeping the overall power in the low‑mid range.

Dimension scores

# Dimension Score Evidence
D1 Engine Accessibility & Consistency 85 Core Mathmech/Ignister group (17 copies) appears in >92% of opening hands (Inferred)
D2 Opening-Hand Quality & Brick Management 60 Hand‑trap/searcher mix yields an estimated brick rate of ~8% (Inferred)
D3 Combo Conversion & Ceiling 70 Potential OTK via Mathmech Synchro/XYZ can reach ~80 PowerIndex in theory (Inferred)
D4 Combo Floor & Median Output 55 Typical midrange board produces median PowerIndex around 55 (Inferred)
D5 Interruption Resilience & Route Redundancy 70 Multiple independent starters and recursion tools give good interruption resilience (Inferred)
D6 Resource Economy, Recovery & Grind 75 Draw engines and GY recursion provide net card advantage over turns (Inferred)
D7 End-Board & Interaction Quality 80 14 cards flagged with negation, plus hand traps, give high interaction density (Verified)
D8 Going-Second & Board-Breaking Power 65 Hand‑trap density and board‑breakers like Twin Twisters and Crossout Designator support going‑second pressure (Inferred)
D9 Offensive Pressure & Closing Power 65 End‑board includes 3000‑ATK Link Dragon and several 2300‑ATK links for solid closing power (Inferred)
D10 Main Deck Efficiency & Flexibility 55 45‑card main deck with only 15% archetype purity spreads resources thin (Inferred)
D11 Extra Deck Efficiency & Coverage 60 All 15 extra‑deck slots filled, though many are generic links, giving moderate coverage (Inferred)
D12 Side Deck Adaptability 30 No side deck present, limiting post‑side adaptability (Verified)
D13 Matchup Coverage & Format Fit 40 No tournament data; matchup fit remains provisional (Provisional)
D14 Pilotability & Error Tolerance 55 Complex decision‑tree with many hand traps and tech choices raises error tolerance (Inferred)

How the score was computed

Strategy profile: Stun. Structural ≈ 62, Going First ≈ 64, Going Second ≈ 60, Meta = provisional, Tournament Reliability ≈ 55. Modifiers: none. Final formula: 0.80*Structural + 0.20*TournamentReliability (Meta provisional)

Probability & combo summary

  • Opening a starter: P(≥1) ≈ 0.92 · key two-card combo ≈ — · full-brick estimate ≈ 0.08 (all Inferred)
  • Combo output: best PowerIndex —, median —, board-per-starter —
  • Turn order: 0 going-first lines vs 0 going-second lines

Strengths

  • Very high hand‑trap and negation density
  • Strong draw and recursion engines
  • Full extra‑deck providing many finishing options

Weaknesses

  • Low archetype purity; many off‑archetype staples dilute focus
  • No side deck limits adaptability after the first game
  • Combo consistency uncertain due to lack of recorded boards

Critical choke points

  • Need at least one Mathmech Circular or Backup @Ignister early to start the engine
  • Reliance on hand‑trap draw engines to recover after disruption
Priority Remove Add Reason
1 Some generic Link monsters (e.g., Link Decoder, Linguriboh) More Mathmech core monsters (e.g., Mathmech Subtraction, Mathmech Addition) Increase archetype purity and improve combo consistency
2 None Side‑deck cards such as Cosmic Cyclone, D.D. Crow, or Twin Twisters variants Add post‑side adaptability and board‑break options

Evidence & confidence

  • Verified: role counts show 14 negation cards; side deck empty; legality status is Legal
  • Inferred: Core group appears in >92% of opening hands; Brick rate estimated at ~8%; Potential OTK ceiling ~80 PowerIndex; Median board PowerIndex ~55; Multiple independent starters give resilience; Draw engines provide net advantage; High interaction density from hand traps and negators; Going‑second board‑breaking potential moderate; End‑board ATK values support closing power; Low archetype purity reduces efficiency; Extra‑deck coverage moderate; Complexity raises error tolerance
  • Provisional: Matchup fit provisional due to missing tournament data
  • Data gaps: no combos supplied — combo floor/median/ceiling is text-only inference no tournament link — archetype meta-share and per-pilot match record absent no win-rate telemetry exists in YGOVN (going-first/second, matchup, game-level, brick/starter/OTK rates) — those signals are Inferred or Unknown Meta Power is Provisional unless a dated metagame sample is supplied
