Kewl Tune Deck #730490 — Yu-Gi-Oh! Master Duel

Kewl Tune — Deck Power Evaluation

Final Contextual Deck Power: 62/100 (±5 · Confidence: Medium)

• Primary strategy: Combo
• Secondary strategies: Control, Grind
• Format: master-duel

Legality

Main 41 / Extra 15 / Side 0 — status: Legal.

Identity & game plan

• Win condition: Synchro Summon into negation/interaction board via Tuner chains, then convert advantage into lethal over subsequent turns; Board-break going-second with hand traps, recover, and swing for lethal
• Turn 1 (going first): Normal Summon Tuner starter (Cue, Mix, or Reco), Special Summon Tuner from hand/Deck, Synchro Summon 1–2 Synchro Tuners for negate/removal/lock effects, hold hand traps for disruption
• Turn 2 (going second): Activate hand traps to interrupt opponent engine, then counter-board with Synchro Summon or lethal swing using remaining resources
• Recovery: Limited without Kewl Tune Remix; relies on searcher chains and Synchro Tuner GY access via effects; vulnerable to single-point disruption
• After siding: N/A — no Side Deck supplied (0/15 cards); no post-game adaptability

Why it scores here

This Kewl Tune deck consistently opens 1–2 Synchro Tuners backed by a 29-card core engine and 14 searchers (Cue, Synchro, Genesis, Mix, Reco), plus a robust 16-card hand-trap suite. The 41-card main deck is efficient, and going-second interaction is strong. However, the deck deviates severely from meta-standard Kewl Tune: missing 9 of 23 core cards, including Kewl Tune Remix (recursion), RS (consistent negation), B2B (offensive finisher), and Loudness War (Tuner protection). This limits ceiling after disruption and mid-game recovery. The complete absence of a Side Deck (0/15) eliminates post-game adaptability entirely. The score reflects a competent Combo opener with solid going-second options, but constrained by incomplete Extra-Deck coverage and no side-deck flexibility. This is scored on the deck as a system—consistency, board quality, and resilience—not by averaging card power scores.

Dimension scores

How the score was computed

Strategy profile: Combo. Structural ≈ 69, Going First ≈ 64, Going Second ≈ 61, Meta = provisional, Tournament Reliability ≈ 60. Modifiers: Missing critical Extra-Deck Synchro Tuners (-5); No Side Deck (-3); Efficient 41-card main deck (2); Strong hand-trap suite (1). Final formula: 0.80·Structural(69) + 0.20·TournamentReliability(60) - 5 modifiers = 62 (Meta Provisional; no dated metagame sample supplied)

Probability & combo summary

• Opening a starter: P(≥1) ≈ 1 · key two-card combo ≈ — · full-brick estimate ≈ 0.11 (all Inferred)
• Combo output: best PowerIndex —, median —, board-per-starter —
• Turn order: 0 going-first lines vs 0 going-second lines

Strengths

• Exceptional opening consistency: 99.89% P(≥1 starter in opening 5); 13 starter copies ensure redundancy even against hand disruption
• Abundant hand-trap suite: 16 copies across 7 distinct cards (Ash, Belle, Veiler, Impermanence, Ghost Mourner, Droll, Maxx C) enable strong going-second interruption and T1 hand extension
• Dense searcher package: 14 searcher-text cards (Kewl Tune Synchro, Cue, Genesis, Mix, Reco, Duelist Genesis, Synchro Overtake, Track Maker) provide redundant access to Kewl Tune cards and Synchro materials
• Efficient 41-card main deck: tight construction minimizes garnet risk and maximizes draw consistency; good 3-of/2-of/1-of ratio
• Synchro Tuner material flexibility: cards like Kewl Tune Mix and Reco allow hand-based Tuners as Synchro materials, bypassing some board disruption
• Dual-layer interaction: Synchro Tuner field effects (negate, destroy, protect) plus 3 Infinite Impermanence for back-row negation

Weaknesses

• Severely off-meta Extra-Deck construction: missing Kewl Tune Remix (recursion + re-access), RS (consistent L5 negation), B2B (offensive finisher + Tuner boost), Loudness War (Tuner protection); 9 of 23 core cards absent = 39.1% core gap
• Limited combo ceiling and multi-chain potential: realistically 1–2 Synchro Tuners without guaranteed follow-ups; missing Remix blocks T2 recursion and Synchro re-access
• Weak grind game and resource regeneration: no explicit recursion engine; relies solely on searchers and Maxx 'C' situational draw; vulnerable to repeated disruption
• No Side Deck = zero post-game adaptability: 0/15 side cards eliminate matchup tech, meta-shift adjustment, and best-of-3 strategy entirely
• Low offensive closing power: boss monsters average 1500–2500 ATK (Zalen 2800 exception); no piercing damage, multi-attack enabler (B2B absent), or burn finisher; lethal typically T3+
• Recovery fragility after board disruption: losing primary Synchro Summon leaves limited alternative lines; no Remix GY resurrection to chain into second board
• Hand-trap redundancy risk: opening 3× Infinite Impermanence, 3× Ghost Belle, or 3× Ash Blossom can clog early-turn hands and leave no summoning resources
• Moderate GY access for searchers: Duelist Genesis requires Tuner on field or in GY; Synchro Overtake requires Synchro in Extra (thinned by searcher usage)

Critical choke points

• Synchro Summon denial: if Kewl Tune Synchro or Cue is negated before resolution (e.g., Ash Blossom stops the search or Veiler chains), backup combo lines collapse; limited alternative path to first Synchro
• Missing Kewl Tune Remix as recovery engine: without recursion, one board wipe = extended setup phase; opponent can grind you out over multiple turns
• Kewl Tune Cue early GY send: if Cue is sent to GY before resolving, Special Summon effect from field is blocked; entire T1 opener stalls unless backup starter is live
• Hand-trap flood: drawing 3× Infinite Impermanence + 3× Ghost Belle + 3× Ash + 2× Droll in opening hand = no board-building resources; turn passes empty-handed
• No side deck for G2/G3 in best-of-3: opponent can pre-side for Kewl Tune's known package without fear of tech adjustments; locked into identical 41-card list across all games
