Kewl Tune Deck #752004 — Yu-Gi-Oh! Master Duel

Deck — Deck Power Evaluation

Final Contextual Deck Power: 30/100 (±10 · Confidence: Medium)

• Primary strategy: Midrange
• Secondary strategies: Stun, Tempo
• Format: master-duel

Legality

Main 40 / Extra 15 / Side 0 — status under the rules at evaluation time: Illegal. 2 violation(s).

Identity & game plan

• Win condition: Synchro summons from the Kewl Tune Tuner web (Loudness War, Track Maker, Remix, RS, B2B) into a board that is protected by hand traps; Fusion and Xyz/Link finishers (Sea Monster of Theseus, Mudragon, Garura, Super Starslayer TY-PHON, S:P Little Knight) once the board is established
• Turn 1 (going first): Turn 1 Normal Summon of a Kewl Tune Tuner (Cue/Mix/Reco/Rotary) to search or Special Summon another Tuner, then Synchro into a Kewl Tune Synchro-Tuner boss while holding hand traps for the opponent's Turn 1 interaction
• Turn 2 (going second): Hold Ash Blossom, Ghost Belle, Effect Veiler, Droll and Infinite Impermanence to answer the opponent's first board, then rebuild Tuner count from GY and Deck through the Kewl Tune Synchro and Mix search chain
• Recovery: Tuners recur from the GY (Kewl Tune Synchro, Duelist Genesis, Ghost Belle banish-GY effects, Visas Amritara and Track Maker summons), so a stripped hand can rebuild Tuner count within one or two turns
• After siding: No Side Deck is registered, so there is no post-side plan to evaluate; the deck is judged on its Main Deck only

Why it scores here

The deck reliably opens a functional Tuner-based engine: P(at least one of the 24 archetype-core copies in a 5-card opening hand) is about 0.99, and 18 Tuners plus 12 searchers give several independent routes to a Synchro summon on turns one and two. Interaction is the strongest part of the system, with 13 hand traps (about 0.92 chance of at least one in a 6-card going-second hand) and 14 removal or negation texts layered behind the Kewl Tune Synchro-Tuner boss. Conversion and median output are only text-inferred because no recorded boards exist, so the score rests on structure and interaction density rather than observed results. The score is not earned by Kewl Tune's popularity or guide hype, and card scores were not averaged. The deck is Illegal: Kewl Tune Cue is over its Master Duel copy limit and Synchro Overtake is Forbidden, so the Final Contextual score is capped and the evaluation is structural only.

Dimension scores

How the score was computed

Strategy profile: Midrange. Structural ≈ 60, Going First ≈ 62, Going Second ≈ 66, Meta = provisional, Tournament Reliability ≈ 55. Modifiers: banlist exposure (-6). Final formula: No reliable metagame: 0.80*Structural + 0.20*TournamentReliability + ContextModifiers = 0.80*60 + 0.20*55 - 6 = 53 uncapped; Illegal legality cap applied, so the reported score is 30 and the evaluation is theoretical/structural-only

Probability & combo summary

• Opening a starter: P(≥1) ≈ 0.99 · key two-card combo ≈ — · full-brick estimate ≈ 0.01 (all Inferred)
• Combo output: best PowerIndex —, median —, board-per-starter —
• Turn order: 0 going-first lines vs 0 going-second lines

Strengths

• Near-certain archetype-core access in opening hands (about 0.99)
• Layered interaction: 13 hand traps plus negation and removal text behind a Tuner boss
• Tuner recursion from the GY gives recovery after a stripped hand
• Strong going-second hand-trap coverage (about 0.92)

Weaknesses

• Illegal list: Kewl Tune Cue at 2 copies over the limit of 1, and Synchro Overtake, which is Forbidden
• No Side Deck, so no post-side adaptability
• Tuner-count dependence makes hands with only one Tuner fragile
• Exact-name purity is only 40 percent, so the engine is partly generic

Critical choke points

• Tuner count on turns one and two: a hand with one Tuner and no searcher stalls the Synchro line
• Fusion access depends on Super Polymerization (2 copies, Semi-Limited)
• Limited-status engine pieces (Kewl Tune Cue, Rotary, Maxx C) restrict copies in a legal list

Recommended changes

Evidence & confidence

• Verified: Legality: 2 violations (Kewl Tune Cue over limit, Synchro Overtake Forbidden); Main 40, Extra 15, Side 0 are within the Master Duel size rules; Copy limits and banlist status for all 21 restricted cards; Core archetype presence: 12 of 25 usage-core cards are in the deck
• Inferred: Opening-hand access probabilities (hypergeometric, Main Deck only); Hand-trap coverage estimates (about 0.92 going second); Recovery through GY Tuner recursion; Interaction density read from card text
• Provisional: Meta Power (no dated metagame sample); Matchup and format fit (D13); Going-first and going-second split of the score
• Data gaps: No recorded combos or boards: combo floor, median and ceiling are text-only inference No tournament link: archetype meta-share and per-pilot records are absent No win-rate telemetry: going-first, going-second and matchup rates are unknown No Side Deck registered for a best-of-3 deck Meta Power is provisional without a dated metagame sample
