Identity & game plan
- Win condition: Kewl Tune Synchro lines into Kewl Tune B2B, Kewl Tune Loudness War and Golden Cloud Beast - Malong for board and damage; Mulcharmy draw-engine card advantage plus Ecclesia and the Dark Dragon board pressure
- Turn 1 (going first): Normal Summon Kewl Tune Cue or Mix, search or Special Summon a Kewl Tune Tuner, then Synchro Summon through Kewl Tune Synchro or Reco into a board-level Synchro
- Turn 2 (going second): Use the hand-trap suite (Ash Blossom, Effect Veiler, Infinite Impermanence, Droll & Lock Bird, Ghost Ogre & Snow Rabbit, Ghost Belle) to stop the opponent's starter, then rebuild the Kewl Tune line from the GY
- Recovery: Kewl Tune Mix and Kewl Tune Reco add Kewl Tune monsters from Deck or GY; Kewl Tune Track Maker and Kewl Tune Clip recur Tuners from the GY
- After siding: Not evaluable: the deck runs no Side Deck (0 cards), so there is no post-side plan
Why it scores here
The list is scored as submitted, and it is Illegal: five Forbidden cards and six over-limit Limited or Semi-Limited cards, so it receives a capped, structural-only score and not a normal Final Contextual score. Structurally the deck is a Kewl Tune Tuner-and-Synchro engine: about 96 percent of opening hands contain at least one archetype core card (Inferred hypergeometric estimate), and the 15 hand traps and 15 negation-text cards give it real interaction density on the end board. Its weaknesses are consistency and recovery: many copies are Limited, the Tuner-heavy hand risks bricks, and the deck has no Side Deck, so it has no post-side plan. No recorded boards exist, so combo floor, median and ceiling are text-only inferences. Popularity of the Kewl Tune archetype is not counted as power, and the score was not produced by averaging card scores.
Dimension scores
| # | Dimension | Score | Evidence |
|---|---|---|---|
| D1 | Engine Accessibility & Consistency | 60 | P(at least one archetype core card in a 5-card opening hand) ~0.97 from the core-group estimate, but several engine cards are over the copy limit and must be cut to 1 (Inferred) |
| D2 | Opening-Hand Quality & Brick Management | 45 | 26 Tuner monsters and 23 level-0 spells create conflicting and dead hands; full-brick proxy ~0.03 with no copy-level simulation (Inferred) |
| D3 | Combo Conversion & Ceiling | 50 | Ceiling is a text read of Kewl Tune Synchro into B2B, Loudness War and Malong, but there are zero parseable boards to confirm it (Inferred) |
| D4 | Combo Floor & Median Output | 40 | No recorded boards, so the median and floor are unknown; a low score reflects the absence of evidence (Inferred) |
| D5 | Interruption Resilience & Route Redundancy | 55 | 15 hand traps and several independent starters (Ash, Effect Veiler, Mix, Reco) give interruption redundancy, though the Kewl Tune line is single-threaded (Inferred) |
| D6 | Resource Economy, Recovery & Grind | 45 | Mulcharmy Fuwalos and Purulia draw on the opponent's summons and Pot of Sloth adds draws, but the Tuner recursion is limited (Inferred) |
| D7 | End-Board & Interaction Quality | 62 | 15 negation-text cards and 15 hand traps give broad interaction, and Synchro Overtake and Solemn Judgment add non-hand-trap answers (Inferred semantic read) |
| D8 | Going-Second & Board-Breaking Power | 45 | Going-second board-breaking relies on hand traps and Kewl Tune restarts; the removal suite was reduced by the Forbidden Crossout Designator and Called by the Grave (Inferred) |
| D9 | Offensive Pressure & Closing Power | 50 | Kewl Tune B2B at 3200 ATK, Loudness War at 3000 DEF and Malong give closing power, but no end-board data exists (Inferred) |
| D10 | Main Deck Efficiency & Flexibility | 40 | Main deck is 55 cards, which must fall to 40 after legal cuts; only 35.7 percent of cards are the exact Kewl Tune name and 45 copies are off-archetype (Verified count, Inferred efficiency) |
| D11 | Extra Deck Efficiency & Coverage | 58 | 11 Synchro and 4 Fusion Extra Deck cards cover the Kewl Tune engine well, and Albion's removal leaves 14 Extra Deck cards (Verified) |
| D12 | Side Deck Adaptability | 15 | The deck has zero Side Deck cards, so no post-side adaptability exists (Verified) |
| D13 | Matchup Coverage & Format Fit | 45 | No tournament link and no dated metagame sample exist, so this dimension is Provisional |
| D14 | Pilotability & Error Tolerance | 40 | The engine requires many Tuner and Synchro steps with several Quick Effect responses, which raises pilot demand (Inferred) |
How the score was computed
Strategy profile: Combo. Structural ≈ 50, Going First ≈ 46, Going Second ≈ 37, Meta = provisional, Tournament Reliability ≈ 40. Modifiers: banlist_exposure (-8); no_side_deck (-4). Final formula: 0.80*Structural + 0.20*TournamentReliability (Meta provisional), then Illegal legality cap applied: modifiers total -12 gives 48-12 = 36, a structural-only capped score
Probability & combo summary
- Opening a starter: P(≥1) ≈ 0.97 · key two-card combo ≈ — · full-brick estimate ≈ 0.03 (all Inferred)
- Combo output: best PowerIndex —, median —, board-per-starter —
- Turn order: 0 going-first lines vs 0 going-second lines
Strengths
- Dense Kewl Tune Tuner package with an archetype core present in about 97 percent of opening hands
- 15 hand traps and 15 negation-text cards give strong interaction
- Eleven Synchro and four Fusion Extra Deck cards offer varied boss options
Weaknesses
- Illegal as submitted: five Forbidden cards and six over-limit cards
- No Side Deck, so no post-side plan
- Heavy Tuner density raises brick and conflict risk
- Only 35.7 percent exact archetype purity
Critical choke points
- Kewl Tune Synchro, Reco and Cue are Limited to 1 copy, so the main engine is reduced to single copies after legal cuts
- Kewl Tune Rotary is Forbidden, removing one of the Tuner starters entirely
Recommended changes
| Priority | Remove | Add | Reason |
|---|---|---|---|
| 1 | Kewl Tune Rotary x3, Albion the Branded Dragon, Called by the Grave, Crossout Designator, Triple Tactics Talent | Legal replacements from the Kewl Tune pool or a stable Tuner starter | These cards are Forbidden in TCG and make the list illegal; removing them is mandatory before any power read |
| 2 | Two copies of Kewl Tune Cue, Kewl Tune Synchro and Kewl Tune Reco; one copy of Ash Blossom, Super Polymerization and Droll & Lock Bird | Single copies of Kewl Tune Cue, Synchro and Reco, plus non-Limited Tuner or search cards | Brings the copy counts within the banlist limits and reduces the risk of dead copies in hand |
| 3 | A few level-0 spells | A Side Deck of 15 cards covering Mulcharmy or other off-archetype threats | The deck currently has no post-side plan, which weakens best-of-3 reliability |
Evidence & confidence
- Verified: Legality status is Illegal with 5 Forbidden and 6 over-limit violations (Verified); Main 55, Extra 15, Side 0 counts (Verified); Archetype purity of 35.7 percent exact name (Verified)
- Inferred: Opening-hand starter access of about 0.97 from the hypergeometric core-group estimate (Inferred); Brick and conflict risk from Tuner density (Inferred); Interaction density from text read of negation and hand-trap cards (Inferred); Ceiling and closing power from card text of Kewl Tune B2B, Loudness War and Malong (Inferred)
- Provisional: Meta power and format fit, since no dated metagame sample or tournament link exists (Provisional)
- Data gaps: No combos supplied, so combo floor, median and ceiling are text-only inference No tournament link, so archetype meta-share and per-pilot match record are absent No win-rate telemetry exists in YGOVN, so going-first and going-second rates are Unknown Meta Power is Provisional unless a dated metagame sample is supplied Deck title is null and no Side Deck exists
