Legality
Main 55 / Extra 15 / Side 0 — status: Illegal. 6 violation(s).
Identity & game plan
- Win condition: Synchro Summon of Kewl Tune B2B, Remix, Loudness War or Crackle, fed by Kewl Tune tuners searched through Cue, Mix, Reco and Synchro; Visas Amritara and Mulcharmy-supported board pressure after hand-trap interaction
- Turn 1 (going first): Normal Summon Kewl Tune Cue or Mix, search a Kewl Tune Tuner, then Synchro into a Kewl Tune boss (theoretical; list is illegal as built)
- Turn 2 (going second): Hold Ash Blossom, Ghost Belle, Droll and Effect Veiler to break the opponent's first engine, then rebuild through Kewl Tune searchers
- Recovery: Kewl Tune Reco and Mix recursion from the GY, plus Mulcharmy draw effects to refill the hand
- After siding: Not evaluable: the deck has no Side Deck (side_count 0)
Why it scores here
The archetype core is well covered: the hypergeometric estimate for at least one Kewl Tune core card in the opening five is about 0.96, so the engine usually comes online (Inferred). Interaction is dense, with roughly 15 hand traps and 11 negation-text cards, which lifts the interruption and end-board scores. The ceiling is text-only because the export contains no recorded boards, so D3 and D4 are inferred from card text and capped by that gap. The score is not driven by Kewl Tune's popularity or by averaging card scores. The deck is Illegal: a Forbidden card and six over-limit cards cap it, so the figure is a theoretical structural read, not a normal final score. The missing Side Deck and absent tournament data pull reliability and matchup fit down.
Dimension scores
| # | Dimension | Score | Evidence |
|---|---|---|---|
| D1 | Engine Accessibility & Consistency | 72 | P(at least one Kewl Tune core card in opening 5) = 0.959 across 25 copies; engine starters searchable through Cue, Mix and Reco (Inferred) |
| D2 | Opening-Hand Quality & Brick Management | 65 | Proxy brick rate 0.041 from the core group; 18 searcher-text cards support hand quality, but 3-copy tuners and Mulcharmy add redundancy and some dead draws (Inferred) |
| D3 | Combo Conversion & Ceiling | 62 | Text-only ceiling: B2B (3200 ATK, Level 10), Remix and Loudness War create strong Synchro boards; no recorded combo boards to confirm (Inferred) |
| D4 | Combo Floor & Median Output | 52 | No combos_evidence; median output cannot be measured and is set near neutral to avoid over-crediting the ceiling (Provisional) |
| D5 | Interruption Resilience & Route Redundancy | 66 | 15 hand traps plus Effect Veiler, Droll and Ghost Belle give several answers to a first disruption; recursion from the GY supports a second line (Inferred) |
| D6 | Resource Economy, Recovery & Grind | 64 | Mulcharmy draw effects, Pot of Prosperity and Kewl Tune searches; recursion through Reco and Mix (Inferred) |
| D7 | End-Board & Interaction Quality | 70 | Loudness War, Kewl Tune RS, Zalen and Effect Veiler negate or protect the board; the interaction density is high (Inferred semantic read) |
| D8 | Going-Second & Board-Breaking Power | 66 | Going-second relies on hand traps (0.868 at least one in 6 cards) and Called by the Grave; no going-second split data (Inferred) |
| D9 | Offensive Pressure & Closing Power | 60 | Closing from B2B 3200 ATK, Visas Amritara 2500 ATK and Remix/Loudness War; tuner recursion extends pressure (Inferred) |
| D10 | Main Deck Efficiency & Flexibility | 55 | 55 main-deck cards in the 40-60 range, but 25 distinct cards with 9 singletons and heavy tuner density; over-limit copies on six cards reduce coherence (Inferred) |
| D11 | Extra Deck Efficiency & Coverage | 60 | 15 Extra cards: 12 Synchro, 2 Fusion, 1 Link; the Synchro core is flexible, but Kewl Tune boss access depends on Tuner searchers (Verified structure, Inferred use) |
| D12 | Side Deck Adaptability | 10 | Side Deck is empty (side_count 0), so post-side adaptability cannot be scored (Verified) |
| D13 | Matchup Coverage & Format Fit | 50 | No tournament_context and no dated metagame sample; archetype meta-share is absent (Provisional) |
| D14 | Pilotability & Error Tolerance | 45 | Multi-step Synchro sequencing with multiple Tuner-search effects and many once-per-turn restrictions raises the decision load; no example combos to verify (Inferred) |
How the score was computed
Strategy profile: Combo. Structural ≈ 62, Going First ≈ 68, Going Second ≈ 60, Meta = provisional, Tournament Reliability ≈ 52. Modifiers: banlist exposure (-8); engine conflicts from copy limits (-4). Final formula: Theoretical: 0.80*Structural(62) + 0.20*TournamentReliability(52) = 60, less context modifiers (-12) = 48, then capped at 30 because the deck is Illegal (copy-limit and Forbidden violations); Meta Provisional; structural-only read
Probability & combo summary
- Opening a starter: P(≥1) ≈ 0.96 · key two-card combo ≈ — · full-brick estimate ≈ 0.04 (all Inferred)
- Combo output: best PowerIndex —, median —, board-per-starter —
- Turn order: 0 going-first lines vs 0 going-second lines
Strengths
- Dense Kewl Tune searchers (Cue, Mix, Reco, Synchro) give high access to the engine
- 15 hand traps plus Effect Veiler and Droll give early interaction
- Extra Deck of 12 Synchro Monsters gives several boss options
Weaknesses
- Illegal as built: Forbidden Kewl Tune Rotary and six over-limit cards
- No Side Deck, so no post-side plan
- No recorded combos or tournament data to verify the ceiling or median
- Heavy tuner density and 9 singletons in a 55-card main
Critical choke points
- Limited Kewl Tune tuners (Cue, Reco, Synchro) must each drop to one copy, weakening the starter redundancy
- Kewl Tune Rotary must be removed entirely
Recommended changes
| Priority | Remove | Add | Reason |
|---|---|---|---|
| 1 | Kewl Tune Rotary (3 copies) | A legal Kewl Tune tuner or searcher within the copy limit | Forbidden card; the deck cannot be legal while it is run |
| 2 | Two copies each of Kewl Tune Cue, Kewl Tune Reco and Kewl Tune Synchro | Non-Limited alternatives or one copy each | Brings the Limited cards to their legal limit of 1 |
| 3 | One copy each of Ash Blossom & Joyous Spring and Super Polymerization | Non-Semi-Limited alternatives | Brings Semi-Limited cards to the legal limit of 2 |
| 4 | None | A 10-15 card Side Deck | Enables a post-side plan and raises D12 |
Evidence & confidence
- Verified: Illegal: Kewl Tune Rotary is Forbidden and six cards exceed their legal copy limit; Main 55 and Extra 15 are within size rules; Side is empty
- Inferred: At least one core Kewl Tune card in opening 5 is about 0.96 (hypergeometric); Interaction density is high based on card text; Going-second hand-trap access is about 0.87
- Provisional: Meta Power (no dated metagame sample); Matchup 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 record absent No win-rate telemetry for going-first/second, matchup or brick rates Meta Power provisional without a dated metagame sample Deck is Illegal as built, so the score is a capped structural read
