Kewl Tune Deck #751125 — Yu-Gi-Oh! Master Duel

Deck — Deck Power Evaluation

Final Contextual Deck Power: 30/100 (±8 · Confidence: Low)

• Primary strategy: Combo
• Secondary strategies: Stun
• Format: master-duel

Legality

Main 40 / Extra 15 / Side 0 — status: Illegal. 3 violation(s).

Identity & game plan

• Win condition: Synchro Summon a Kewl Tune Synchro Monster (Remix, B2B, RS, Crackle, Track Maker, Loudness War) off a Tuner-dense hand and grind the board through Kewl Tune tuner chains; Ecclesia and the Dark Dragon / Albion the Branded Dragon / Golden Cloud Beast - Malong as non-Kewl Tune finishers, with the Branded/Dogmatika Fallen spell as a removal and recursion tool
• Turn 1 (going first): Normal Summon Kewl Tune Cue or Mix from hand to search or revive another Tuner, Synchro Summon a Kewl Tune Synchro Monster, and use Duelist Genesis or Kewl Tune Synchro to reach the Synchro extra-deck threats
• Turn 2 (going second): Use hand traps (Ash Blossom, Ghost Belle, Effect Veiler, Infinite Impermanence, Maxx C, Kewl Tune Clip) to break the opponent's board, then rebuild a Synchro line from the Tuner-heavy GY
• Recovery: Kewl Tune recursion from GY via Mix, Reco, Rotary, and Cue search effects plus Over Tuning to re-Special Summon Tuners and rebuild the Synchro engine
• After siding: Not evaluable: the deck has no side deck (side_count 0), so there is no post-side plan

Why it scores here

The deck is scored as a system, not as an average of its card scores. Its engine is dense and reliable on paper: 26 copies of the Kewl Tune core put at least one core card in the opening hand about 99.7% of the time (Inferred), and the 16-card searcher text group and 12-card hand-trap group keep the starter line and interaction accessible on both turn orders. Interaction is the strongest part of the structure: 12 hand traps with negation text and a Kewl Tune Synchro line that can reach Synchro Summons from a Tuner-heavy hand, so the deck should be able to contest a board on the opponent's turn. Conversion and median output are text-only inferences because no combo boards were supplied, so they are capped and labelled Inferred. The deck has no side deck and no post-side plan, and there is no tournament or win-rate data, so Meta Power is null and D12 and D13 are weak. Usage popularity was not counted as strength, and the guide claim that the archetype is the strongest in the current meta was not used as evidence. The final score is capped low because the list is illegal in Master Duel: one Forbidden card, and two other cards over their copy limits.

Dimension scores

How the score was computed

Strategy profile: Combo. Structural ≈ 60.3, Going First ≈ 58, Going Second ≈ 62, Meta = provisional, Tournament Reliability ≈ 52. Modifiers: illegal_list_cap (-12); no_side_deck (0). Final formula: Structural 60.3 (Combo profile). Unconstrained: 0.80*60.3 + 0.20*52 = 58.6, then modifier -12 gives 46.6. Illegal list (Forbidden card, two copy-limit breaches): capped at 30 and labelled theoretical/structural-only.

Probability & combo summary

• Opening a starter: P(≥1) ≈ 1 · key two-card combo ≈ — · full-brick estimate ≈ 0 (all Inferred)
• Combo output: best PowerIndex —, median —, board-per-starter —
• Turn order: 0 going-first lines vs 0 going-second lines

Strengths

• Core Kewl Tune engine is near-certain to appear in the opening hand (~99.7%, Inferred)
• Layered interaction: 12 hand traps and 12 negation-text cards
• Extra Deck is fully used: 13 Synchro, 1 Link, 1 Fusion
• Clear primary plan: Tuner chains into Kewl Tune Synchro Monsters

Weaknesses

• Illegal list: Synchro Overtake (Forbidden), Fallen & Virtuous (3 of 2), Kewl Tune Cue (2 of 1)
• No side deck, so no post-side plan (D12 = 25)
• Tuner-heavy hands risk dead Tuner draws without a Synchro partner (Inferred)
• No measured combo boards or win-rate data

Critical choke points

• Kewl Tune Synchro and Tuner availability: most lines need a Tuner in hand or GY plus a Kewl Tune Synchro
• Hand-trap density: going-second lines depend on hand traps; Ash Blossom and Ghost Belle are the key interaction
• Forbidden Synchro Overtake is a search/summon route that must be removed, so the replacement route must be checked

Evidence & confidence

• Verified: Legality: Illegal under BanMasterDuel; Synchro Overtake Forbidden; Fallen & Virtuous 3 of 2; Kewl Tune Cue 2 of 1; Main 40, Extra 15, Side 0 (within size rules); Extra Deck breakdown: 13 Synchro, 1 Link, 1 Fusion; Archetype purity 38.2% exact name; 21 Kewl Tune copies
• Inferred: P(at least one core Kewl Tune card in opening hand) ~0.997; Hand-trap group P(>=1 in going-second 6-card hand) ~0.90; Engine consistency and brick rate (hypergeometric and text-based); Interaction density from negation and hand-trap text; Going-first and going-second structural estimates
• Provisional: Meta Power (no dated metagame sample); Matchup and format fit (no tournament link)
• Data gaps: No combos supplied: combo floor, median and ceiling are text-only inference No tournament link: archetype meta-share and per-pilot records absent No win-rate telemetry: going-first/second, matchup and brick rates are Inferred Meta Power is Provisional without a dated metagame sample Data conflict: usage_statistics flags Kewl Tune Track Maker as not in this deck (copies_in_deck 0), but the cards list shows it in Extra x2 Kewl Tune RS (x2) is in the deck but absent from usage core and missing lists; its usage is not checked No side deck, so no post-side evidence
