| Going First | 60 |
| Going Second | 64 |
| Meta Power | provisional |
| Tournament Reliability | 50 |
- Primary strategy: Combo

Legality
Main 55 / Extra 15 / Side 0 — status under the rules at evaluation time: Illegal. 10 violation(s).
Identity & game plan
- Win condition: Kewl Tune Synchro boards (Kewl Tune B2B, Zalen, Visas Amritara, Ecclesia, Malong) built off Tuner chains started by Kewl Tune Cue, Reco, Mix and Clip; Hand-trap-supported Synchro pressure through Nibiru and interaction-backed boards
- Turn 1 (going first): Normal Summon a Tuner (Cue, Reco, Mix or Clip), use its search or Special Summon, then Synchro Summon a Kewl Tune Synchro boss while keeping Ash Blossom or Effect Veiler up
- Turn 2 (going second): Use hand traps (Ash Blossom, Effect Veiler, Ghost Belle, Droll and Lock Bird, Ghost Ogre) on the opponent's starter, then rebuild a Tuner chain from the hand and GY
- Recovery: Kewl Tune Reco and Mix recursion from the Deck or GY, Duelist Genesis and Synchro Overtake for searching, plus Pot of Prosperity or Sloth for card flow
- After siding: Not evaluable: side_count is 0, so no post-side plan exists in this list
Why it scores here
The deck's core engine is well stocked: 26 Tuners and 16 searchers give a high chance (about 0.95 for at least one archetype card in a 5-card opener, Inferred) of starting a Tuner chain. Its 14 Synchro Extra Deck monsters convert that chain into large boards, and the Synchro boss ceiling (Kewl Tune B2B at 3200 ATK, Zalen at 2800) is high. Interaction is dense (15 negation texts, 28 removal texts, 13 hand traps), which is what carries the going-second score. The deck is scored on this system, not by averaging card scores, and popularity of the Kewl Tune archetype did not add points. No combo boards, guides or tournament data exist, so the median and matchup scores are Inferred or Provisional and the score is capped because the list is illegal.
Dimension scores
| # | Dimension | Score | Evidence |
|---|---|---|---|
| D1 | Engine Accessibility & Consistency | 70 | P(at least one archetype core card in 5-card hand) = 0.95 over 24 core copies; Tuner density 26 (Inferred) |
| D2 | Opening-Hand Quality & Brick Management | 55 | 26 Tuners and 16 searchers suggest moderate brick risk, but 13 hand traps add functional dead-hand cover (Inferred) |
| D3 | Combo Conversion & Ceiling | 62 | Synchro boss ceiling is high (B2B 3200, Zalen 2800, Visas 2500), but no recorded boards exist to confirm it (Inferred) |
| D4 | Combo Floor & Median Output | 45 | No parseable boards; median output cannot be measured and is estimated from text only (Inferred) |
| D5 | Interruption Resilience & Route Redundancy | 62 | Two independent starter families (Tuner chain and hand-trap responses) plus Reco and Mix recursion give some interruption redundancy (Inferred) |
| D6 | Resource Economy, Recovery & Grind | 60 | Pot of Prosperity, Pot of Sloth, Duelist Genesis and recursive Tuners give card flow (Inferred) |
| D7 | End-Board & Interaction Quality | 72 | 15 negation texts and 3 Solemn-family cards, with Solemn Judgment and Synchro Overtake supporting the line (Inferred from card text) |
| D8 | Going-Second & Board-Breaking Power | 68 | 13 hand traps give about 0.82 chance of at least one going second (Inferred, hypergeometric) |
| D9 | Offensive Pressure & Closing Power | 62 | Several Synchro bosses reach 2500+ ATK, but there is no board or damage data (Inferred) |
| D10 | Main Deck Efficiency & Flexibility | 50 | Only 35.7% exact-name archetype purity, with 45 off-archetype copies and copy-limit overflow, which hurts coherence (Verified composition) |
| D11 | Extra Deck Efficiency & Coverage | 60 | 14 Synchro monsters with one Fusion monster; the Fusion slot is dead because Albion is Forbidden (Verified legality) |
| D12 | Side Deck Adaptability | 15 | Side deck is empty (0 cards), so no post-side adaptability exists (Verified) |
| D13 | Matchup Coverage & Format Fit | 50 | No tournament or meta sample; matchup fit cannot be verified (Provisional) |
| D14 | Pilotability & Error Tolerance | 40 | Multi-step Tuner chains with many once-per-turn effects and many decision points raise error risk (Inferred) |
How the score was computed
Strategy profile: Combo primary, Midrange secondary (structural weights not blended; Combo profile used as-is). Structural ≈ 59.6, Going First ≈ 60, Going Second ≈ 64, Meta = provisional, Tournament Reliability ≈ 50. Modifiers: banlist_exposure (-8); copy_limit_overflow (-3); no_side_deck (-2); illegal_cap (-17). Final formula: Illegal list: no normal Final score. Structural 59.6 (Combo profile, D13 provisional at 50) with TR 50 gives 0.80*59.6 + 0.20*50 = 57.7; modifiers -11 give 46.7; capped to 30 because the deck is Illegal and the evaluation is structural-only.
Probability & combo summary
- Opening a starter: P(≥1) ≈ 0.95 · 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 Tuner base for Kewl Tune chains
- Large Synchro boss pool with high ATK ceiling
- Heavy interaction density across hand traps and spell/trap negation
- Strong going-second hand-trap coverage
Weaknesses
- Illegal list: four Forbidden cards and several copy-limit overflows
- Low archetype purity (35.7%) with many off-archetype copies
- Empty side deck
- Fusion slot wasted on a Forbidden card
Critical choke points
- Kewl Tune Cue, Reco and Synchro are each limited to 1 copy, so the 3-copy build cannot be legal
- Engine depends on Tuner chains, so loss of the Tuner base collapses the Synchro plan
Recommended changes
| Priority | Remove | Add | Reason |
|---|---|---|---|
| 1 | Kewl Tune Rotary x3, Called by the Grave, Triple Tactics Talent, Albion the Branded Dragon | Legal Tuner or Synchro support cards from the archetype pool | Forbidden cards make the list illegal; this is required before any normal score applies |
| 2 | Extra copies of Kewl Tune Cue, Reco, Synchro and Ash Blossom beyond legal limits | Single copies of the archetype's limited cards plus second copies of unlimited Tuners | Brings copy counts within the banlist limits without losing the engine core |
| 3 | Nothing (main deck stays at 40 to 60 cards) | A 15-card side deck with anti-hand-trap and anti-spell/trap cards | Gives post-side adaptability (D12 currently 15) |
Evidence & confidence
- Verified: Illegal status: four Forbidden cards and multiple over-limit copies (legality block); Main 55 and Extra 15 are within size rules; Side deck count is 0; Exact-name archetype purity 35.7%
- Inferred: Opening-hand starter probability about 0.95; Going-second hand-trap probability about 0.82; Structural dimension scores D1 to D14 derived from card text and probability estimates
- Provisional: Meta Power (no dated metagame sample); Matchup fit D13 (no tournament data)
- Data gaps: No combos supplied: floor, median and ceiling are text-only inference No tournament link: archetype meta-share and pilot record absent No win-rate telemetry for going-first, going-second, matchup or brick rate Side deck empty, so no post-side evidence Meta Power provisional without a dated metagame sample
