Kewl Tune Deck #761602 — Yu-Gi-Oh! Master Duel

Deck — Deck Power Evaluation

Final Contextual Deck Power: 47/100 (±10 · Confidence: Low)

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

Legality

Main 40 / Extra 15 / Side 0 — status under the rules at evaluation time: Illegal. 3 violation(s).

Identity & game plan

• Win condition: Synchro Summon Kewl Tune Tuner-based boss monsters (Kewl Tune Remix, Kewl Tune B2B, Kewl Tune Loudness War) from a Tuner-heavy hand, then close with the boss's ATK and board control.; Hand-trap-supported Synchro lines that remove the opponent's interaction and then convert with a Tuner boss.
• Turn 1 (going first): Open a Tuner (Kewl Tune Mix, Kewl Tune Reco or Kewl Tune Cue) with a searcher, Normal Summon a second Tuner, and Synchro Summon a Kewl Tune boss while keeping Ash Blossom, Effect Veiler or Ghost Belle as protection.
• Turn 2 (going second): Hold Ash Blossom, Effect Veiler, Ghost Belle or Infinite Impermanence to negate the opponent's first board-building effect, then rebuild the Tuner engine on the opponent's turn or in the Main Phase.
• Recovery: Recover through the Tuner searchers (Kewl Tune Mix, Kewl Tune Reco, Kewl Tune Synchro, Duelist Genesis) and GY Tuner recursion (Kewl Tune Clip, Ghost Belle) to rebuild a Synchro after a hand trap is spent.
• After siding: No side deck is registered (side_count 0), so there is no post-side plan to evaluate.

Why it scores here

The deck is scored as a system: a Tuner-dense Kewl Tune engine that reliably opens a Tuner and a searcher, converts into a Synchro boss, and protects that line with a large hand-trap suite (Ash Blossom, Effect Veiler, Ghost Belle, Infinite Impermanence, Ghost Ogre). The structural read is about 61.5 on Combo weights; the strength comes from the Tuner-to-Synchro engine, its interaction density, and its going-second protection, not from the card scores averaged together. Archetype popularity earned no points and the guides only confirm the list is real. The list is Illegal (Synchro Overtake is Forbidden, and Fallen & Virtuous and Kewl Tune Cue are over their copy limits), so the 47 is a theoretical, structural-only figure and is capped low. Combo and tournament data are absent, so the floor, median and ceiling are inferred from card text.

Dimension scores

How the score was computed

Strategy profile: Combo. Structural ≈ 61.5, Going First ≈ 60, Going Second ≈ 64, Meta = provisional, Tournament Reliability ≈ 50. Modifiers: banlist exposure / illegal list (-12). Final formula: 0.80*Structural + 0.20*TournamentReliability (Meta provisional); 0.80*61.5 + 0.20*50 = 59.2, then -12 banlist/copy-limit modifier = 47 (theoretical, structural-only because the list is Illegal)

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

• Dense Tuner engine with high archetype-core access (P ≈ 0.99 in a 5-card opening hand)
• Large hand-trap and negation suite that protects the Synchro line on both turns
• Synchro Extra Deck with several boss options and Tuner recursion

Weaknesses

• Illegal list: Synchro Overtake is Forbidden, and two cards exceed their Limited/Semi-Limited copy counts
• No side deck registered, so no post-side plan
• Synchro-only Extra Deck and Tuner-only lines are fragile against Tuner-lock and Tuner-removal

Critical choke points

• Needs at least two Tuners on the field for most Synchro summons
• Synchro Overtake (Forbidden) is a shortcut that cannot be run as written

Recommended changes

Evidence & confidence

• Verified: Illegal status: Synchro Overtake Forbidden at 1 copy; Fallen & Virtuous 3 vs 2; Kewl Tune Cue 2 vs 1; Composition: 40 Main, 15 Extra, 0 Side; 14 Synchro and 1 Fusion in the Extra Deck; Card text role hints for hand traps, searchers and removal
• Observed: Usage stats show the Kewl Tune core (Rotary, Clip, Mix, Ash Blossom) at 100% inclusion in the sampled archetype data
• Inferred: Starter access P ≈ 0.99 from hypergeometric estimates; Interaction density and going-second strength from card text; Synchro boss closing power from card stats and conditions
• Provisional: Meta Power (no dated metagame sample); Matchup and format fit (no tournament link)
• Data gaps: no combos supplied, so floor/median/ceiling is text-only inference no tournament link, so archetype meta-share and per-pilot match record are absent no win-rate telemetry exists in YGOVN no side deck registered Meta Power is Provisional unless a dated metagame sample is supplied
