Identity & game plan

  • Win condition: Kewl Tune Synchro Summons (Kewl Tune Remix, Track Maker, B2B, RS, Crackle, Loudness War) pressuring the board with Tuner-based Synchro lines; Non-Kewl Tune Synchro bosses (Zalen, Golden Cloud Beast - Malong, Enigmaster Packbit, Visas Amritara, Despian Luluwalilith) when the Kewl Tune line is interrupted
  • Turn 1 (going first): Normal Summon a Kewl Tune Tuner (Cue, Mix, Reco or Clip), search a Kewl Tune card, and Synchro Summon into a Kewl Tune boss; hand traps (Ash, Infinite Impermanence, Effect Veiler, Ghost Belle) are held for the opponent's first activation
  • Turn 2 (going second): Use the six-card hand's hand traps (15 in deck) to answer the opponent's first board, then rebuild a Tuner and Synchro Summon the engine through the resulting open field
  • Recovery: Revive or search Tuners from GY via Kewl Tune effects and Synchro again; Ghost Ogre and Ghost Belle recursion and Jet Synchron GY effect are the recovery routes
  • After siding: Not evaluable: the deck has an empty Side Deck, so no post-side plan exists in the evidence

Why it scores here

The deck is scored as a system on its Kewl Tune Synchro engine, its 15 hand-trap and interaction cards, and its Extra Deck coverage, not as an average of card scores. Starter access is moderate: about 75 percent of opening hands contain at least one of the 13 Kewl Tune core cards, but three-copy starters each show only about 25 percent per opening hand, so the engine is reliable only as a repeated draw-and-search system. Interaction density is high (15 hand traps, 17 searchers, 28 removal-text cards), which supports resilience and going-second play, but the list has no recorded combos, so combo conversion is an inferred structural read only. Popularity and archetype-usage signals were not used to add points, and the deck has no side deck, which removes post-side credit. Because the list is illegal in TCG (three Forbidden copies and five over-limit Limited or Semi-Limited cards), the score is capped at structural-only and is not a normal contextual score.

Dimension scores

# Dimension Score Evidence
D1 Engine Accessibility & Consistency 60 P(at least one of a 3-copy starter in a 5-card opening hand) ≈ 0.25; P(at least one Kewl Tune core card in hand) ≈ 0.75; searcher-text group P ≈ 0.85 (Inferred)
D2 Opening-Hand Quality & Brick Management 48 21 level-0 spell/trap cards and 15 hand-trap cards compete with 29 distinct main cards; many Tuner-only hands are dead without a Synchro partner (Inferred)
D3 Combo Conversion & Ceiling 52 No recorded boards; Kewl Tune Synchro and Tuner-substitution text suggest a multi-step Synchro line but ceiling is text-only (Inferred)
D4 Combo Floor & Median Output 42 No combo median or power distribution available; floor cannot be measured from the evidence (Provisional)
D5 Interruption Resilience & Route Redundancy 58 15 hand traps, two Ash Blossoms and Infinite Impermanence give multiple independent interruption answers and Tuner recursion via GY effects (Inferred)
D6 Resource Economy, Recovery & Grind 45 Recovery via Ghost Ogre, Ghost Belle and Jet Synchron GY effects, plus Pot of Prosperity and Pot of Sloth draw; no resource data (Inferred)
D7 End-Board & Interaction Quality 60 Interaction density is high by text count (negation 18, removal 28); Kewl Tune Loudness War and Kewl Tune B2B add extra-deck protection and Tuner lock text (Inferred)
D8 Going-Second & Board-Breaking Power 50 Going-second six-card hands face 15 hand traps (P ≈ 0.86 for at least one) but no board-breaking data; Lightning Storm and Harpie's Feather Duster are the only board-breakers (Inferred)
D9 Offensive Pressure & Closing Power 45 Kewl Tune B2B at 3200 ATK and Kewl Tune Loudness War are the main closers; no end-board or damage data (Verified stat / Inferred)
D10 Main Deck Efficiency & Flexibility 52 56 main cards with 29 distinct, copy histogram 14 singles, 3 doubles, 12 triples; compact but 8 legality violations reduce it (Verified)
D11 Extra Deck Efficiency & Coverage 60 15 Synchro cards with 12 distinct, offering several bosses and Tuner-substitution options (Verified count / Inferred use)
D12 Side Deck Adaptability 10 Side deck is empty (0 cards), so there is no post-side adaptability (Verified)
D13 Matchup Coverage & Format Fit 45 No tournament or metagame data; the archetype is not measured against the format (Provisional)
D14 Pilotability & Error Tolerance 40 Many Tuner-substitution and once-per-turn sequencing rules; decision points are numerous (Inferred)

How the score was computed

Strategy profile: Combo. Structural ≈ 53, Going First ≈ 52, Going Second ≈ 50, Meta = provisional, Tournament Reliability ≈ 40. Modifiers: Banlist exposure (illegal) (-10). Final formula: Illegal cap: 0.80*Structural(53) + 0.20*TournamentReliability(40) + Modifiers(-10) = 40.4, capped to 20 because the list is Illegal in TCG; structural-only, not a normal contextual score

Probability & combo summary

  • Opening a starter: P(≥1) ≈ 0.25 · 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 and negation suite (15 hand traps, 18 negation-text cards) gives strong resilience on going second
  • Kewl Tune Synchro engine has many Tuner searchers (17 searcher-text cards) and redundant Tuner routes
  • Compact main deck (56 cards, 29 distinct) with a Synchro-heavy Extra Deck of 15

Weaknesses

  • Illegal in TCG: 3 Forbidden copies and 5 over-limit Limited/Semi-Limited cards
  • No side deck, so no best-of-3 adaptation
  • No recorded combos, so ceiling and median output cannot be measured

Critical choke points

  • Kewl Tune Synchro and the Kewl Tune Tuner set are the only route to most bosses; removing the Limited copies cuts the engine
  • Three Kewl Tune Rotary are Forbidden, so the list cannot be played as built
Priority Remove Add Reason
1 Kewl Tune Rotary x3, Called by the Grave x1, Triple Tactics Talent x1 Legal replacements (non-Forbidden) or fewer slots Forbidden cards make the list illegal; fixing this is required before any contextual score
2 Excess copies: Kewl Tune Cue, Kewl Tune Synchro, Kewl Tune Reco down to 1 each; Ash Blossom down to 2; Droll & Lock Bird down to 1 Legal alternatives Copy-limit violations; the Limited-list copies are the engine's most important cards, so keep one of each
3 None A 15-card Side Deck Side deck is empty; best-of-3 play needs a post-side plan and this will also improve D12

Evidence & confidence

  • Verified: Legality: 8 copy-limit violations, Illegal status (56 main, 15 extra, 0 side); Banlist statuses for Kewl Tune Rotary, Called by the Grave, Triple Tactics Talent (Forbidden) and Limited/Semi-Limited cards; Archetype spread: Kewl Tune 26, generic 24, Mulcharmy 5, Synchro 4
  • Observed: Usage stats show Ash Blossom, Called by the Grave and Droll & Lock Bird as core cards in the archetype
  • Inferred: Hypergeometric starter, core and hand-trap probabilities; Strategy classification as Midrange with Tempo and Toolbox secondaries; Interaction and resilience dimension scores from card text
  • Provisional: Meta Power (null, no dated metagame sample); D13 matchup and format fit (no tournament context)
  • Data gaps: No combos supplied: combo floor, median and ceiling are text-only inference No tournament link: archetype meta-share and per-pilot match record absent No win-rate telemetry; going-first/second, matchup and brick rates are Inferred Meta Power is provisional without a dated metagame sample Side deck is empty; no post-side evidence Archetype label 'Synchron' does not match the Kewl Tune-dominated card pool (26 Kewl Tune copies vs 5 Synchron-named cards)
