Legality
Main 55 / Extra 15 / Side 0 — status: Illegal. 4 violation(s).
Identity & game plan
- Win condition: Synchro Summon Kewl Tune B2B, Kewl Tune Loudness War or Kewl Tune Crackle off the Kewl Tune Tuner engine, then press with ATK and board control; Kewl Tune RS and Kewl Tune Remix as negation and pressure bodies on the Synchro field
- Turn 1 (going first): Normal Summon Kewl Tune Cue to special summon a Tuner, search with Kewl Tune Mix or Reco, then Synchro Summon into Kewl Tune B2B or Loudness War
- Turn 2 (going second): Hold up hand traps (Ash Blossom, Ghost Ogre and Snow Rabbit, Ghost Belle, Effect Veiler, Infinite Impermanence, Droll and Lock Bird) to blank the opponent's board or first summon, then rebuild a Tuner-based Synchro line
- Recovery: Recycle Tuners from the GY through Kewl Tune Mix, Reco and Clip, and re-Synchro from the GY-backed Tuner pool
- After siding: None: the deck runs no Side Deck, so there is no post-side plan in the evidence
Why it scores here
The Kewl Tune core is almost always accessible: the usage-stat core group gives a hypergeometric P(at least one core card in a 5-card hand) of about 0.99 (Inferred), and the Tuner pool supplies redundant Synchro material and multiple independent starters. Conversion is real but unmeasured: no recorded boards exist, so the ceiling (Kewl Tune B2B and Loudness War) and the median output are read from card text only (Inferred). Interaction is dense for a Synchro deck, with 16 negation-text and 17 hand-trap copies. The deck is not scored on popularity; the archetype usage stats confirm the list is real but do not raise the score. The score is also capped low because the list is illegal: three cards exceed their copy limits and Ash Blossom exceeds its Semi-Limited limit, and the deck has no side deck. The score was not produced by averaging card scores.
Dimension scores
| # | Dimension | Score | Evidence |
|---|---|---|---|
| D1 | Engine Accessibility & Consistency | 66 | P(at least one archetype core card in 5) ~0.99; Kewl Tune starters redundant across Cue, Mix, Reco, Clip (Inferred) |
| D2 | Opening-Hand Quality & Brick Management | 55 | 25 Tuners and 16 Spells create some dead or conflicting hands; hand-trap density is high (Inferred) |
| D3 | Combo Conversion & Ceiling | 58 | Ceiling read from text only: B2B and Loudness War Synchro lines; no recorded boards (Inferred) |
| D4 | Combo Floor & Median Output | 48 | Median output unknown: no combos supplied; floor estimated from starter redundancy (Inferred) |
| D5 | Interruption Resilience & Route Redundancy | 60 | Multiple Tuner-recursion and Synchro routes allow continuation after one disruption (Inferred) |
| D6 | Resource Economy, Recovery & Grind | 50 | Search chain (Mix, Reco, Duelist Genesis, Synchro Overtake) and GY recursion; no resource data (Inferred) |
| D7 | End-Board & Interaction Quality | 62 | 17 hand-trap and 16 negation-text copies; 1-for-1 interaction, no floodgate (Inferred) |
| D8 | Going-Second & Board-Breaking Power | 52 | Raigeki, Lightning Storm, Crossout Designator and Called by the Grave, but thin board breaking (Inferred) |
| D9 | Offensive Pressure & Closing Power | 60 | Kewl Tune B2B 3200 ATK and Loudness War 3000 DEF closers; direct text read (Inferred) |
| D10 | Main Deck Efficiency & Flexibility | 52 | 55 main cards with 44.3% exact-name purity and 39 off-archetype copies; over-limit cards dilute compactness (Verified composition, Inferred) |
| D11 | Extra Deck Efficiency & Coverage | 60 | 15 Synchro cards, mostly Kewl Tune; 8 distinct Extra Deck cards (Verified composition) |
| D12 | Side Deck Adaptability | 10 | No side deck; zero post-side adaptability (Verified) |
| D13 | Matchup Coverage & Format Fit | 40 | No tournament link and no dated meta sample; Meta Power provisional (Provisional) |
| D14 | Pilotability & Error Tolerance | 45 | Multi-step Synchro chains and many hand-trap timings raise decision load (Inferred) |
How the score was computed
Strategy profile: Combo. Structural ≈ 56, Going First ≈ 55, Going Second ≈ 50, Meta = provisional, Tournament Reliability ≈ 45. Modifiers: banlist_exposure (-4); no_side_deck (-3). Final formula: Structural 56 with no dated meta: 0.80*56 + 0.20*45 = 53.8; context modifiers -7 gives 46.8; the deck is Illegal, so the result is capped at 35 as a structural-only score
Probability & combo summary
- Opening a starter: P(≥1) ≈ 0.99 · 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
- Core archetype access near-certain (P 0.99, Inferred)
- Redundant Tuner recursion and Synchro routes (Inferred)
- Dense hand-trap and negation coverage (Verified text flags, Inferred semantics)
Weaknesses
- Illegal list: copy limits exceeded on Kewl Tune Cue, Synchro, Reco and Ash Blossom
- No side deck
- Median and ceiling unmeasured: no recorded boards
- Mulcharmy and Stardust splash adds 8 off-archetype copies
Critical choke points
- Kewl Tune Mix or Reco as the search engine: a dead draw is a lost turn-1
- Single Synchro Extra Deck slot holding B2B lines on going-second boards
Recommended changes
| Priority | Remove | Add | Reason |
|---|---|---|---|
| 1 | 2x Kewl Tune Cue, 2x Kewl Tune Synchro, 2x Kewl Tune Reco, 1x Ash Blossom & Joyous Spring | Legal copies: 1 Cue, 1 Synchro, 1 Reco, 2 Ash Blossom; add non-limited Tuner or search cards in the freed slots | The list is Illegal; without this change no normal score applies |
| 2 | None | A 10-15 card Side Deck | Restores post-side plans and removes the D12 zero |
Evidence & confidence
- Verified: Main 55, Extra 15, Side 0 within size rules; Copy-limit violations on Kewl Tune Cue, Kewl Tune Synchro, Kewl Tune Reco and Ash Blossom; Archetype purity 44.3%, Synchro-heavy Extra Deck of 15 copies
- Observed: Archetype usage stats: core inclusion 100% for the listed core cards (not a win rate)
- Inferred: Hypergeometric starter access 0.99 for the archetype core group; Hand-trap density and interaction quality from card text; Combo ceiling and floor from text only
- Provisional: Meta Power and D13 matchup fit: no dated metagame sample
- 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 exists in YGOVN Meta Power provisional unless a dated metagame sample is supplied Deck is Illegal (copy-limit violations), so no normal Final Contextual score is issued
