Legality
Main 55 / Extra 15 / Side 0 — status under the rules at evaluation time: Illegal. 4 violation(s).
Identity & game plan
- Win condition: Synchro Summon Kewl Tune boss monsters (Kewl Tune B2B, Chaos Angel, Kewl Tune Loudness War) off a Tuner-heavy Main Deck; Stun and hand-trap interaction (Ash Blossom, Effect Veiler, Ghost Belle, Ghost Ogre, Nibiru) that buys time for the Synchro line
- Turn 1 (going first): Normal Summon a Kewl Tune Tuner, search another Kewl Tune with Mix, Reco or Synchro, then Synchro into a boss; hold hand traps for the opponent's first activation
- Turn 2 (going second): Hold 2 to 3 hand traps and negate the opponent's starter or search; Synchro through the surviving board on the next turn
- Recovery: Mulcharmy draw effects and Duelist Genesis / JJ Kewl Tune searchers rebuild hand after a hand-trap exchange
- After siding: No side deck is registered, so no post-side plan can be evaluated
Why it scores here
This list is illegal as built: four cards exceed their OCG copy limits, so the score is a structural read capped low and is not a normal Final Contextual score. The core Kewl Tune engine is accessible, with a 0.86 hypergeometric chance of at least one archetype card in a 5-card opening hand, and 20 hand traps plus 24 removal or negation texts make the deck resilient and strong on the second turn. Its conversion ceiling (Kewl Tune B2B, Chaos Angel, Kewl Tune Loudness War) rests on text inference only, because no recorded boards exist, so median output is scored low. The deck mixes Mulcharmy, PSY-Frame, Greed, Solemn and Visas cards into a Kewl Tune core (only 38.6 percent exact-name purity), which costs efficiency. The score reflects the system: consistency, interaction and going-second strength, not the popularity of the archetype and not an average of card scores.
Dimension scores
| # | Dimension | Score | Evidence |
|---|---|---|---|
| D1 | Engine Accessibility & Consistency | 62 | P(>=1 archetype card in 5-card hand) ~0.86 across 17 core copies; Synchro starters are concentrated but duplicated (Inferred) |
| D2 | Opening-Hand Quality & Brick Management | 58 | 20 hand traps and 17 searchers give functional hands; some redundant Tuners and dead Synchro starts in hand (Inferred) |
| D3 | Combo Conversion & Ceiling | 60 | Ceiling from card text only: Tuner-chained Synchro into B2B or Chaos Angel; no recorded boards (Inferred) |
| D4 | Combo Floor & Median Output | 45 | No recorded boards, so the median is unknown and scored conservatively (Provisional) |
| D5 | Interruption Resilience & Route Redundancy | 68 | Multiple independent hand-trap answers and Mulcharmy draw recover after one interruption (Inferred) |
| D6 | Resource Economy, Recovery & Grind | 60 | Searchers and Mulcharmy draw refill cards; Synchro material cost is high (Inferred) |
| D7 | End-Board & Interaction Quality | 75 | 17 negation and 24 removal texts across hand traps and Extra Deck monsters (Verified card text) |
| D8 | Going-Second & Board-Breaking Power | 72 | 20 hand traps give strong going-second interaction against an opponent's establishing board (Inferred) |
| D9 | Offensive Pressure & Closing Power | 62 | Kewl Tune B2B at 3200 ATK and Chaos Angel at 3500 ATK close games; no recorded win data (Verified stat, Inferred) |
| D10 | Main Deck Efficiency & Flexibility | 50 | 55 Main Deck cards with 43 off-archetype copies and a 26-distinct spread; engine conflicts across sub-archetypes (Verified composition) |
| D11 | Extra Deck Efficiency & Coverage | 60 | 15 Synchro Extra Deck cards with 9 distinct, no Fusion or Link; mostly Kewl Tune coverage (Verified composition) |
| D12 | Side Deck Adaptability | 15 | No Side Deck registered, so no post-side adaptation is possible (Verified) |
| D13 | Matchup Coverage & Format Fit | 45 | No tournament or meta-share data; placeholder pending a dated meta sample (Provisional) |
| D14 | Pilotability & Error Tolerance | 35 | Multi-step Tuner chains with several once-per-turn gates and a 55-card list demand high pilot skill (Inferred) |
How the score was computed
Strategy profile: Midrange. Structural ≈ 58, Going First ≈ 52, Going Second ≈ 64, Meta = provisional, Tournament Reliability ≈ 45. Modifiers: Banlist exposure (-6); Engine conflicts (-4); No side deck (-2). Final formula: Illegal cap applied: uncapped 0.80*Structural(58.45) + 0.20*TournamentReliability(45) + modifiers(-12) = 44, capped to 30 for copy-limit violations (theoretical/structural-only)
Probability & combo summary
- Opening a starter: P(≥1) ≈ 0.86 · 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
- 20 hand traps and 17 negation texts give strong second-turn interaction
- Archetype core accessible at 0.86 in opening hand
- Synchro boss suite (B2B, Chaos Angel, Loudness War) gives high closing power
Weaknesses
- Illegal copy limits on four cards
- No side deck
- Heavy off-archetype spread dilutes the engine
- Long multi-step Tuner chains are demanding to pilot
Critical choke points
- Kewl Tune Mix/Reco/Synchro starters, which are limited to one copy each in the legal list
- Single Tuner needed for every Synchro Summon
Recommended changes
| Priority | Remove | Add | Reason |
|---|---|---|---|
| 1 | 2 copies of Kewl Tune Cue, Synchro, or Reco (one of each over the limit) | Equivalent non-Limited Tuner or searcher, such as an extra Kewl Tune Mix or Kewl Tune Playlist | Brings the list to legal copy counts; without this the deck cannot be played in OCG |
| 2 | 1 Ash Blossom copy | A non-Semi-Limited hand trap such as Ghost Ogre or Effect Veiler (already at 3) | Ash Blossom exceeds its 2-copy OCG limit |
| 3 | Off-archetype staples (Solemn Judgment, Pot of Prosperity) | Side deck slots for Kewl Tune counters | Reduces engine dilution and gives a post-side plan |
Evidence & confidence
- Verified: Four copy-limit violations and eight Limited cards per legality check; Hand trap, negation and removal card texts
- Inferred: At least one archetype card in opening hand is about 0.86; Going-second interaction strength from 20 hand traps
- Provisional: Meta and format fit (D13); Tournament reliability
- Data gaps: No combos supplied, so floor, median and ceiling are text-only inference No tournament link, so meta-share and match records are absent No side deck registered No dated metagame sample; Meta Power is null
