Legality

Main 40 / Extra 0 / Side 0 — status: Legal.

Identity & game plan

  • Win condition: Mist Archfiend (2400 ATK) and Vampire Grimson as main-deck beatsticks, backed by generic removal and draw; Chip damage from Mist Archfiend's self-destruct (1000 damage) and Zombowwow pressure
  • Turn 1 (going first): Draw spells (Cup of Ace, Magical Mallet, Royal Magical Library) to find a Mist Archfiend or removal; hold Solemn Strike or Solemn Judgment for the first summon
  • Turn 2 (going second): Use Ghost Belle as a hand trap to negate an opposing activation, then Raigeki or Raigeki Break to clear the board
  • Recovery: Plaguespreader Zombie recurs from the GY, and draw spells refill the hand
  • After siding: No side deck: no post-side plan exists

Why it scores here

The deck scores low because it does not form a connected engine: only 3 of 40 cards carry the exact Archfiend name, and the rest are generic spells, traps and off-archetype monsters (exact-name purity 7.5%). It reliably opens with draw spells and reaches its removal suite (Raigeki, Raigeki Break, Mystical Space Typhoon, Fairy Wind, Solemn pair), so it can answer a single threat. Its closing power is thin: Mist Archfiend and Vampire Grimson are the only real boss threats, and no recorded boards exist to show a conversion ceiling. The Extra Deck is empty and the Side Deck is empty, which removes both Extra-Deck coverage and post-side adaptation. Popularity did not earn points, and no card scores were averaged into the deck score.

Dimension scores

# Dimension Score Evidence
D1 Engine Accessibility & Consistency 35 Starter-level probability per specific card is about 0.125 (1 copy, going first) and no multi-card line is evidenced; engine accessibility is low (Inferred)
D2 Opening-Hand Quality & Brick Management 40 28 level-0 spells and traps with 18 Spells make most hands non-committal, but the draw spells mitigate bricks (Inferred)
D3 Combo Conversion & Ceiling 30 No parseable boards; the ceiling rests on Mist Archfiend plus removal with no recorded conversion (Inferred)
D4 Combo Floor & Median Output 25 No combo evidence for median output; the text-only read is weak (Inferred)
D5 Interruption Resilience & Route Redundancy 40 Plaguespreader Zombie recursion and draw spells give some recovery, but there is no independent second line (Inferred)
D6 Resource Economy, Recovery & Grind 50 Three draw sources (Cup of Ace, Magical Mallet, Royal Magical Library) support resource regeneration (Inferred)
D7 End-Board & Interaction Quality 60 Two Solemn cards, Raigeki Break, Fairy Wind, Trap Trick and Ghost Belle give broad interaction (Verified text, Inferred quality)
D8 Going-Second & Board-Breaking Power 50 Raigeki, Ghost Belle and Solemn provide board breaking when going second, but there is no board-breaker density evidence (Inferred)
D9 Offensive Pressure & Closing Power 35 Mist Archfiend at 2400 ATK is the main threat, with Vampire Grimson and Zombowwow as secondary bosses (Verified stats, Inferred pressure)
D10 Main Deck Efficiency & Flexibility 50 40 cards with 20 distinct names and a flexible toolbox structure; some slots are generic (Verified composition)
D11 Extra Deck Efficiency & Coverage 15 Zero Extra Deck cards, so no Extra-Deck coverage at all (Verified)
D12 Side Deck Adaptability 15 Zero Side Deck cards means no post-side adaptation (Verified)
D13 Matchup Coverage & Format Fit 45 No tournament context or dated meta sample; format fit is Provisional
D14 Pilotability & Error Tolerance 60 Few multi-step combos and simple draw-plus-removal play lower pilot error risk (Inferred)

How the score was computed

Strategy profile: Toolbox. Structural ≈ 39, Going First ≈ 38, Going Second ≈ 40, Meta = provisional, Tournament Reliability ≈ 40. Modifiers: No coherent engine (-3); No side deck (-2). Final formula: 0.80*Structural + 0.20*TournamentReliability + ContextModifiers (Meta provisional)

Probability & combo summary

  • Opening a starter: P(≥1) ≈ 0.13 · 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 removal and interaction suite (Raigeki, Raigeki Break, MST, Fairy Wind, Solemn pair, Trap Trick)
  • Three draw spells give resource regeneration
  • Simple, low-step play pattern

Weaknesses

  • No real engine: 3 of 40 cards are exact Archfiend names
  • Only 2 real boss threats (Mist Archfiend, Vampire Grimson)
  • Empty Extra Deck and Side Deck
  • Core card Maxx C is missing (70% usage)

Critical choke points

  • Mist Archfiend is the only consistent threat, and its removal shuts down the plan
  • Without a Side Deck, a hostile matchup has no adjustment
Priority Remove Add Reason
1 Chain Energy Maxx "C" Chain Energy taxes both players' LP, and Maxx "C" is the 70%-usage core card this deck lacks
2 Abyssal Designator An Archfiend Extra Deck boss The deck runs no Extra Deck; the archetype guide notes Archfiend Extra Deck bosses as its threat base
3 Toon World Additional Archfiend-named monsters Toon World is off-archetype; raising exact-name purity improves engine coherence

Evidence & confidence

  • Verified: Legal 40-card Main Deck, 0 Extra, 0 Side; Solemn Judgment and Solemn Strike are each 1 copy (Limited); Exact Archfiend name purity 7.5%; Maxx C missing (70% usage); Ghost Belle present (60% usage)
  • Inferred: Starter draw probability and brick rate; Going-first and going-second interaction value; Recovery through Plaguespreader Zombie
  • Provisional: Meta and matchup fit (no dated sample)
  • Data gaps: No combos supplied: combo floor, median and ceiling are text-only inference No tournament link: meta-share and match record absent No win-rate telemetry: going-first, going-second, matchup and brick rates are Inferred Meta Power is Provisional unless a dated metagame sample is supplied
