Legality
Main 56 / Extra 11 / Side 0 — status under the rules at evaluation time: Illegal. 5 violation(s).
Identity & game plan
- Win condition: Kewl Tune Synchro chains into a large Kewl Tune Synchro boss (Kewl Tune B2B 3200 ATK, Chaos Angel 3500 ATK) after the Tuner count is built; Hand-trap and removal interaction (Ash Blossom, Ghost Ogre & Snow Rabbit, Ghost Belle & Haunted Mansion, Effect Veiler, Droll & Lock Bird) grinds the opponent out of the board
- Turn 1 (going first): Normal Summon Kewl Tune Cue or Reco, search a Kewl Tune card with Kewl Tune Synchro or Kewl Tune Mix, then Synchro Summon through the Kewl Tune Synchro text (Inferred from card text; no combo data)
- Turn 2 (going second): Hold Ash Blossom, Ghost Ogre & Snow Rabbit, Ghost Belle & Haunted Mansion and Effect Veiler to answer the opponent's first board, then rebuild with Synchro Overtake or Kewl Tune Synchro (Inferred)
- Recovery: Recover through Kewl Tune Reco and Kewl Tune Mix recursion from the GY and the 14 searcher-text cards (Inferred)
- After siding: Not evaluable: the deck has no Side Deck (0 cards), so there is no post-side plan
Why it scores here
The deck is scored as a connected Kewl Tune Synchro system, not as an average of its card scores. Its engine is reasonably accessible: the 14 searcher-text cards give about 78% odds of at least one search in a 5-card opening hand (Inferred), and the Extra Deck carries several strong Kewl Tune Synchro bosses with real closing power. Interaction is the deck's strongest layer, with 16 hand traps and 20 negation-text cards, so it can answer an opponent's first board and then rebuild. The deck loses points on conversion and consistency: there are no recorded boards, so the combo floor and median are text-only inference, and only 36% of the Main Deck's copies are exact Kewl Tune names, which spreads the engine across Branded, Phantasm, PSY-Frame and Synchro support. The score is capped low because the list breaks the OCG copy limit on five cards (including Kewl Tune Cue, Kewl Tune Synchro and Kewl Tune Reco at 3 copies against a limit of 1), and it has no Side Deck, so it is evaluated as theoretical and structural only; popularity and meta-share did not earn any points.
Dimension scores
| # | Dimension | Score | Evidence |
|---|---|---|---|
| D1 | Engine Accessibility & Consistency | 50 | P(>=1 searcher in 5-card hand) = 0.78; Kewl Tune core group P(open >=1) = 0.55; 8 core copies in deck (Inferred) |
| D2 | Opening-Hand Quality & Brick Management | 48 | 34 Tuners in the Main Deck, 16 hand traps and 14 searcher-text cards; brick and conflict risk estimated from text, not measured (Inferred) |
| D3 | Combo Conversion & Ceiling | 45 | Ceiling from Kewl Tune Synchro text (search plus immediate Synchro Summon) into 3200-3500 ATK bosses; no recorded boards (Inferred) |
| D4 | Combo Floor & Median Output | 40 | combos_evidence has 0 parseable boards, so median and floor cannot be measured; scored low for lack of data (Inferred) |
| D5 | Interruption Resilience & Route Redundancy | 62 | Multiple independent interaction starters (Ash Blossom, Ghost Ogre & Snow Rabbit, Ghost Belle & Haunted Mansion, Effect Veiler) and GY recursion from Kewl Tune Reco and Mix (Inferred) |
| D6 | Resource Economy, Recovery & Grind | 58 | Searchers and GY recursion (Kewl Tune Reco, Kewl Tune Mix) recover resources; no float or spend data (Inferred) |
| D7 | End-Board & Interaction Quality | 68 | Interaction density is high: Illusion Gate, Synchro Emergency, Solemn Accusation, Harpie's Feather Duster, Droll & Lock Bird and hand traps, with 33 removal-text cards (Verified text, Inferred quality) |
| D8 | Going-Second & Board-Breaking Power | 60 | Strong hand-trap set for going second, with 88% odds of a hand trap in a 6-card hand (Inferred); board-breaking is text-only |
| D9 | Offensive Pressure & Closing Power | 62 | Extra Deck bosses reach 3200-3500 ATK (Kewl Tune B2B, Chaos Angel) with direct and piercing text; no end-board sample (Verified stats, Inferred closing) |
| D10 | Main Deck Efficiency & Flexibility | 42 | 56 Main Deck cards with 26 distinct names, 13 cards at 3 copies and a Tuner-heavy mix; compactness is low for an engine deck (Verified counts) |
| D11 | Extra Deck Efficiency & Coverage | 60 | 11 Extra Deck cards, 8 distinct, all Synchro with several Kewl Tune coverage monsters; mandatory-slot count is high (Verified counts) |
| D12 | Side Deck Adaptability | 10 | No Side Deck at all (0 cards), so there is no post-side adaptability (Verified) |
| D13 | Matchup Coverage & Format Fit | 45 | No tournament link and no archetype share in the export; meta fit is provisional (Provisional) |
| D14 | Pilotability & Error Tolerance | 35 | Synchro chains, Tuner timing and hand-trap timing across many cards require high decision load (Inferred) |
How the score was computed
Strategy profile: Combo. Structural ≈ 52, Going First ≈ 50, Going Second ≈ 55, Meta = provisional, Tournament Reliability ≈ 35. Modifiers: Illegal copy-limit violation (-12); Limited/Semi-Limited key cards (0). Final formula: 0.80*Structural(52) + 0.20*TournamentReliability(35) - 12 illegal copy-limit modifier = 36.6, rounded to 37; theoretical/structural-only because the list is Illegal; Meta provisional (null)
Probability & combo summary
- Opening a starter: P(≥1) ≈ 0.78 · 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
- Interaction density: hand traps, negation text and removal text across the Main Deck
- Extra Deck bosses with high ATK and direct effect text
- Searchers and GY recursion give recovery
Weaknesses
- Illegal as built: five cards over the OCG copy limit
- No Side Deck, so no post-side plan
- Off-archetype dilution: only 35.8% exact Kewl Tune names
- No recorded combos or tournament data to validate conversion
Critical choke points
- Kewl Tune Synchro is the main searcher and Synchro enabler; at 3 copies it is over the limit
- Most Synchro lines need a Kewl Tune Tuner in the GY or hand, so an early hand-trap exchange can leave no engine
Recommended changes
| Priority | Remove | Add | Reason |
|---|---|---|---|
| 1 | One copy each of Ash Blossom & Joyous Spring, The Fallen & The Virtuous and Kewl Tune Cue, Kewl Tune Synchro, Kewl Tune Reco | Non-Limited replacements (not chosen by this evaluator) | Make the list legal to play; a copy-limit violation blocks any normal score |
| 2 | Off-archetype support cards (e.g. Phantasm, Solemn, Branded copies) | More exact Kewl Tune cards | Raises engine accessibility and exact-name purity |
| 3 | A Side Deck of 5 to 15 cards | Enables a post-side plan and raises the side-deck dimension from 10 |
Evidence & confidence
- Verified: Illegal status: five cards over OCG copy limit; 56 Main, 11 Extra, 0 Side, all within OCG size rules; Banlist statuses for all Limited and Semi-Limited cards
- Inferred: Searcher probability 0.78 in 5-card hand (hypergeometric); Hand-trap probability 0.88 in 6-card hand (hypergeometric); Interaction and board-breaking quality from card text; Pilotability and error tolerance
- Provisional: Meta fit (D13) without a dated meta sample; Tournament reliability
- Data gaps: no combos supplied: combo floor, median and ceiling are text-only inference no tournament link: archetype meta-share and per-pilot record are absent no win-rate telemetry (going-first/second, matchup, brick and OTK rates) no Side Deck, so post-side and side-adaptability cannot be assessed Meta Power is provisional unless a dated metagame sample is supplied
