Legality

Main 56 / Extra 15 / Side 0 — status under the rules at evaluation time: Illegal. 3 violation(s).

Identity & game plan

  • Win condition: Fiendsmith and Kewl Tune Extra Deck boards (Fiendsmith's Lacrima, Kewl Tune RS, Kewl Tune B2B) reached through the Fiendsmith and Kewl Tune searcher and Synchro chain; no Magikey card is present to win with.; Magical Musket Link and Fusion pressure, with Fiendsmith's Agnumday and Magical Musketeer Max as Link follow-ups.
  • Turn 1 (going first): Open a Fiend or Kewl Tune searcher (Kewl Tune Mix, Fiendsmith's Tract, Fiendsmith Engraver) and go to a Fiendsmith or Kewl Tune Extra Deck summon, protected by Effect Veiler or Ash Blossom behind the rest of the turn.
  • Turn 2 (going second): Hold Ash Blossom, Solemn Warning, Effect Veiler and Droll & Lock Bird to interrupt the opponent's first summon or search, then go to the Extra Deck with a Fiendsmith monster.
  • Recovery: Recover from interruption with Mulcharmy draw effects, Fiendsmith Lacrima's GY recursion, and Kewl Tune Mix / Reco searches back to the hand.
  • After siding: No Side Deck is registered, so there is no post-side plan.

Why it scores here

This list is not a Magikey deck: it contains no Magikey-named card and 0 of 25 archetype-core cards, and it runs three Forbidden cards (Aerial Eater, Cross-Sheep, D/D/D Wave High King Caesar), so it is Illegal and receives a capped, structural-only score. The structure is a Fiendsmith, Kewl Tune and Magical Musket toolbox, and the score comes from its system properties: 9 searcher-text cards give about a 60% chance of at least one searcher in a 5-card opening hand (Inferred), so the engine is accessible but spread across three sub-archetypes. Interaction is the strongest area, with 11 hand traps, 14 negation-text cards and 16 removal-text cards, which earns the going-second score. Consistency, resource economy and closing power are weak because no recorded boards, no win-rate telemetry and no Side Deck exist to confirm conversion. The score is not an average of card scores, and popularity of the label was not counted.

Dimension scores

# Dimension Score Evidence
D1 Engine Accessibility & Consistency 40 Searcher-text group P(>=1 in opening 5) about 0.60 across 9 searchers, but no single starter repeats enough to be reliable (Inferred)
D2 Opening-Hand Quality & Brick Management 42 11 hand traps and 9 searchers compete for hand space, and sub-archetype pieces (Fiendsmith, Kewl Tune, Musket) are often dead together (Inferred)
D3 Combo Conversion & Ceiling 35 No parseable boards, so the ceiling rests on text reads of Fiendsmith Lacrima and Kewl Tune RS / B2B (Inferred)
D4 Combo Floor & Median Output 35 No recorded combo median is available; the usual output is unknown beyond text reads (Inferred)
D5 Interruption Resilience & Route Redundancy 50 Two independent interruption routes, Mulcharmy draw and Kewl Tune Mix search, plus redundant hand traps (Inferred)
D6 Resource Economy, Recovery & Grind 40 Recursion exists (Fiendsmith Lacrima, Mulcharmy draws) but Limited copies and dead-card risk lower economy (Inferred)
D7 End-Board & Interaction Quality 62 14 negation-text and 16 removal-text cards, with Forbidden cards removed from the list, give broad interaction (Inferred semantic read)
D8 Going-Second & Board-Breaking Power 55 11 hand traps and Solemn Warning give strong going-second interaction, but no going-second split data exists (Inferred)
D9 Offensive Pressure & Closing Power 38 The closing threats are mainly Fiendsmith Lacrima (Limited) and Kewl Tune B2B / RS; no end-board ATK data beyond card stats (Inferred)
D10 Main Deck Efficiency & Flexibility 45 56 Main Deck cards with 29 singletons is bloated for one plan, including Pot of Avarice with no Greed engine (Inferred)
D11 Extra Deck Efficiency & Coverage 45 15 Extra Deck slots, but 3 of them are Forbidden (Illegal), and the rest are spread over three sub-archetypes (Verified legality, Inferred efficiency)
D12 Side Deck Adaptability 10 No Side Deck is registered, so post-side adaptability is absent (Verified)
D13 Matchup Coverage & Format Fit 35 No tournament link or dated meta sample; the archetype label has no core cards present (Provisional)
D14 Pilotability & Error Tolerance 30 Three sub-archetype engines with many decision points and Quick Effect timing make the deck hard to pilot (Inferred)

How the score was computed

Strategy profile: Toolbox. Structural ≈ 42, Going First ≈ 38, Going Second ≈ 46, Meta = provisional, Tournament Reliability ≈ 30. Modifiers: Banlist exposure: Forbidden cards run (-8); Banlist exposure: Limited key cards (-4). Final formula: 0.80*Structural + 0.20*TournamentReliability + ContextModifiers (Meta provisional); illegal-list cap applied, theoretical/structural-only
