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
Recommended changes
| 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
