Legality
Main 56 / Extra 15 / Side 0 — status under the rules at evaluation time: Illegal. 8 violation(s).
Identity & game plan
- Win condition: Synchro Summon Kewl Tune Tuner monsters and Synchro bosses (Loudness War, Track Maker, Remix, RS, B2B) to pressure the board; Mid-game board pressure from Synchro boss effects and negation
- Turn 1 (going first): Normal Summon Kewl Tune Cue or Mix, search a Kewl Tune card, and Synchro Summon a Kewl Tune boss; not verified by combo data
- Turn 2 (going second): Hand traps (Infinite Impermanence, Ash Blossom, Effect Veiler, Ghost Belle) on the opponent's starter, then rebuild a Synchro board from the remaining hand
- Recovery: Kewl Tune Mix and Reco search Kewl Tune monsters from Deck or GY, and Jet and Starjunk Synchron recur from the GY as Tuners
- After siding: Not evaluable: the deck has no Side Deck
Why it scores here
The list is structurally dense in the Kewl Tune core: 27 archetype copies give a 0.97 chance of at least one in a 5-card opening hand, and each 3-copy starter has about a 0.25 chance of appearing in that hand. The Synchro boss suite and a hand-trap package of about 15 cards give the deck a plausible interaction layer on both the going-first and going-second turns. Recorded combo data is absent, so the ceiling and median come only from card text and are Inferred. The score is held down by legality: three Forbidden cards and five over-limit Limited or Semi-Limited cards make the list Illegal, and the deck runs no Side Deck. The score is not built from averaging card scores, and archetype popularity earned no points.
Dimension scores
| # | Dimension | Score | Evidence |
|---|---|---|---|
| D1 | Engine Accessibility & Consistency | 70 | P(at least one of a 3-copy starter in 5 cards) = 0.25 per card; 27 archetype copies give P(at least one) = 0.97 (Inferred) |
| D2 | Opening-Hand Quality & Brick Management | 55 | About 15 hand traps and 17 searchers reduce dead draws, but the Synchro and Tuner overlap creates redundant bricks (Inferred) |
| D3 | Combo Conversion & Ceiling | 50 | No recorded boards; the ceiling is read from Kewl Tune boss text and multi-step Synchro lines (Inferred, text only) |
| D4 | Combo Floor & Median Output | 45 | No recorded boards, so the median is unknown; starter diversity is moderate and the Synchro lines depend on the same Tuners (Inferred) |
| D5 | Interruption Resilience & Route Redundancy | 60 | Several independent Tuner routes and GY recursion (Jet and Starjunk Synchron) give some recovery after one disruption (Inferred) |
| D6 | Resource Economy, Recovery & Grind | 55 | Searchers and GY recursion regenerate resources; Extra Deck use is 15 Synchro cards (Inferred from text) |
| D7 | End-Board & Interaction Quality | 65 | Hand traps plus Synchro boss negation and Lightning Storm or Harpie's Feather Duster give layered interaction (Inferred semantic read) |
| D8 | Going-Second & Board-Breaking Power | 55 | Going-second value comes from hand traps plus negation; no going-second combo data exists (Inferred) |
| D9 | Offensive Pressure & Closing Power | 50 | Synchro bosses with 2500 to 3200 ATK and Kewl Tune B2B's second attack give closing power, with no closing-rate data (Inferred) |
| D10 | Main Deck Efficiency & Flexibility | 60 | 56 Main cards with 29 distinct cards; about 37 percent exact-archetype purity leaves some off-plan slots (Verified composition, Inferred) |
| D11 | Extra Deck Efficiency & Coverage | 55 | 15 Synchro cards are all used, but the Extra Deck is entirely Synchro, with no Fusion or Link flexibility (Verified composition) |
| D12 | Side Deck Adaptability | 20 | No Side Deck, so post-side adaptability is 0 by construction (Verified) |
| D13 | Matchup Coverage & Format Fit | 40 | No tournament link, so meta fit is Provisional; the Illegal status caps any fit read (Provisional) |
| D14 | Pilotability & Error Tolerance | 40 | Long Synchro sequences and many once-per-turn effects raise the decision load (Inferred) |
How the score was computed
Strategy profile: Combo. Structural ≈ 56, Going First ≈ 55, Going Second ≈ 50, Meta = provisional, Tournament Reliability ≈ 40. Modifiers: banlist exposure (-8); copy-limit violations (-4). Final formula: No reliable metagame: 0.80*Structural(56) + 0.20*TournamentReliability(40) + Modifiers(-12) = 40.8, then capped to 30 because the deck is Illegal (theoretical/structural-only)
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 archetype core (27 copies) gives high starter access in the opening hand
- Layered interaction from about 15 hand traps and Synchro boss negation
- Multiple Tuner routes and GY recursion give some interruption recovery
Weaknesses
- Illegal as built: three Forbidden cards and five over-limit cards
- Zero Side Deck, so no post-side plan
- No recorded combos or tournament data, so ceiling and median are text-based
Critical choke points
- Kewl Tune Rotary is Forbidden and appears in 3 copies, so the core Tuner route is unavailable as built
- Synchro boss summoning depends on a small number of Tuners in hand or GY
Recommended changes
| Priority | Remove | Add | Reason |
|---|---|---|---|
| 1 | Kewl Tune Rotary (3), Called by the Grave (1), Triple Tactics Talent (1) | Legal substitutes, such as Kewl Tune Mix, Clip or Effect Veiler copies | These cards are Forbidden, so the list cannot be played in TCG as built |
| 2 | Excess copies of Kewl Tune Cue, Reco, Synchro and Droll & Lock Bird | Reduce to the Limited caps (1 copy each), filling the slots with Kewl Tune or hand-trap alternatives | Copy-limit violations make the list Illegal |
Evidence & confidence
- Verified: Legality: 3 Forbidden cards and 5 over-limit cards; 56 Main, 15 Extra, 0 Side; Archetype composition: 26 exact Kewl Tune copies, 36.6 percent purity; Archetype core presence: 27 copies, P(at least one in hand of 5) = 0.9689
- Inferred: Starter access per card and the core-density consistency read; Interaction layering from card text; Going-first and going-second plans from text
- Provisional: Meta fit (D13) and the Meta Power dimension, with no dated metagame sample
- Data gaps: No combos supplied, so ceiling, median and conversion are text-only inference No tournament link, so archetype meta-share and pilot records are absent No Side Deck, so the post-side dimension cannot be evaluated No win-rate telemetry exists in YGOVN
