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 high-ATK Kewl Tune and Chaos Angel / Kewl Tune B2B boss monsters from the Extra Deck after a Tuner-chain opening; Recovering Tuners from GY and banishment to rebuild a second Synchro board through Kewl Tune Track Maker, Remix and Crackle
- Turn 1 (going first): Normal Summon a Kewl Tune Tuner, search or summon a second Tuner, and Synchro Summon a Kewl Tune Synchro monster; hold Ash Blossom, Ghost Ogre and Effect Veiler for the opponent's first response
- Turn 2 (going second): Use hand traps (Ash Blossom, Ghost Ogre, Effect Veiler, Nibiru, Ghost Ogre) to break the opponent's board, then rebuild a Tuner-based Synchro line from the GY
- Recovery: Tuners returned to GY or banished feed Kewl Tune RS and Track Maker effects; Duelist Genesis and Synchro Overtake supply searches
- After siding: No side deck is registered, so no post-side plan can be evaluated
Why it scores here
The deck opens a functional Synchro plan in most hands: P(at least one of a 3-copy starter in a 5-card opening hand) is about 0.25 and the 10-copy Kewl Tune core has P(at least one in hand) of about 0.65 (Inferred). Its 11 hand traps and 18 negation-text cards give strong interaction density, which drives the interaction and going-second scores. Ceiling and median output cannot be measured because no combo boards were recorded, so those scores are text-only and provisional. Popularity was not used: the archetype usage stats show only 33% of the core present, and the deck is not scored by averaging card scores. The deck is Illegal (three Limited/Semi-Limited cards over the copy limit), so the Final score is capped at 30 and the result is structural-only.
Dimension scores
| # | Dimension | Score | Evidence |
|---|---|---|---|
| D1 | Engine Accessibility & Consistency | 60 | P(>=1 3-copy starter in 5-card opening hand) = 0.25; Kewl Tune core P(>=1 in hand) = 0.65 with 10 copies (Inferred) |
| D2 | Opening-Hand Quality & Brick Management | 50 | 47 of 55 main copies are off-archetype and 11 hand-trap copies compete for hand space; brick risk estimated from composition (Inferred) |
| D3 | Combo Conversion & Ceiling | 60 | No parseable boards in combos_evidence; ceiling is text-only from Synchro chains and Kewl Tune effects (Inferred) |
| D4 | Combo Floor & Median Output | 45 | No recorded combo median or power distribution; floor cannot be measured (Provisional) |
| D5 | Interruption Resilience & Route Redundancy | 65 | Multiple hand traps and negation text provide independent answers after disruption; starter diversity is moderate (Inferred) |
| D6 | Resource Economy, Recovery & Grind | 60 | 14 searcher-text cards, Duelist Genesis and Synchro Overtake supply resource recovery (Inferred) |
| D7 | End-Board & Interaction Quality | 75 | 18 negation-text cards, 31 removal-text cards and 11 hand traps give broad interaction (Inferred semantic) |
| D8 | Going-Second & Board-Breaking Power | 65 | Going-second hand traps and Tuner recovery from GY give a credible board break; no going-second split data (Inferred) |
| D9 | Offensive Pressure & Closing Power | 65 | Extra Deck closers include Chaos Angel ATK 3500, Kewl Tune B2B ATK 3200 and Kewl Tune Loudness War ATK 3000 (Verified stats) |
| D10 | Main Deck Efficiency & Flexibility | 50 | 55 main copies over 25 distinct cards with 12 three-of slots; over-limit copies lower legal efficiency (Verified composition) |
| D11 | Extra Deck Efficiency & Coverage | 60 | 15 Synchro Extra Deck cards across 12 distinct entries, with Kewl Tune Synchro-access coverage (Inferred) |
| D12 | Side Deck Adaptability | 10 | No Side Deck registered (side_count 0), so no adaptability is available (Verified) |
| D13 | Matchup Coverage & Format Fit | 40 | No tournament link and no dated meta sample; archetype share unavailable (Provisional) |
| D14 | Pilotability & Error Tolerance | 55 | Multi-step Tuner chains with several once-per-turn effects and Synchro material routing raise decision load (Inferred) |
How the score was computed
Strategy profile: Combo primary; Stun secondary used for interaction emphasis but not blended into weights. Structural ≈ 58, Going First ≈ 56, Going Second ≈ 60, Meta = provisional, Tournament Reliability ≈ 45. Modifiers: banlist exposure (-12). Final formula: 0.80*Structural(58) + 0.20*TournamentReliability(45) + banlist modifier(-12) = 43, then Illegal cap to 30 (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 hand-trap and negation suite (11 hand traps, 18 negation-text cards)
- Strong Extra Deck closers (Chaos Angel, Kewl Tune B2B, Kewl Tune Loudness War)
- Kewl Tune core has high presence (10 copies, P(>=1 in hand) about 0.65)
Weaknesses
- Illegal copy counts on four Limited/Semi-Limited cards
- No Side Deck registered
- Low core completeness: only 4 of 12 usage-stat core cards are present
Critical choke points
- Legal copy-limit fix forces removal of up to 6 copies of Kewl Tune staples, which may break the Tuner chain
- Single Tuner-chain opening with no recorded alternative route
Recommended changes
| Priority | Remove | Add | Reason |
|---|---|---|---|
| 1 | Two of the three Kewl Tune Cue, Kewl Tune Synchro and Kewl Tune Reco copies | Second copies of cards with no copy limit (e.g. Kewl Tune Mix or Kewl Tune Clip), if their roles fit | Brings the list within Limited and Semi-Limited limits so it can be scored normally |
| 2 | One Ash Blossom & Joyous Spring copy | A non-restricted hand trap or Tuner | Ash Blossom Semi-Limited limit is 2 |
| 3 | Nothing | A Side Deck of 15 cards | Side deck is empty, so post-side adaptability cannot be assessed |
Evidence & confidence
- Verified: Main 55 / Extra 15 / Side 0 counts within OCG size rules; Four copy-limit violations against Limited and Semi-Limited status; Extra Deck stats for Chaos Angel, Kewl Tune B2B and Kewl Tune Loudness War
- Observed: Usage stats: 4 of 12 archetype core cards present (33.3%)
- Inferred: Opening-hand starter probabilities from the hypergeometric estimate; Interaction density from text role hints; Synchro chain complexity and pilotability
- Provisional: Meta power (no dated sample); Matchup fit (no tournament link); Combo floor and median (no recorded boards)
- 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; going-first/second and matchup rates unknown No Side Deck registered Meta Power is provisional without a dated metagame sample
