Kewl Tune Deck #751541 — Yu-Gi-Oh! TCG

Deck — Deck Power Evaluation

Final Contextual Deck Power: 25/100 (±10 · Confidence: Low)

• Primary strategy: Combo
• Secondary strategies: Midrange, Synchro
• Format: tcg

Legality

Main 55 / Extra 15 / Side 0 — status: Illegal. 6 violation(s).

Identity & game plan

• Win condition: Synchro Summon Kewl Tune Synchro monsters (Track Maker, Remix, RS, Loudness War, B2B) from a Tuner-heavy hand and sustain pressure through the Kewl Tune Tuner loop; Interaction-backed resolution through hand traps and Synchro Overtake, with Kewl Tune Playlist and Lightning Storm as board-clearing or recovery tools
• Turn 1 (going first): Normal Summon a Kewl Tune Tuner, use Kewl Tune Mix or Reco to search a Kewl Tune card, then Synchro Summon into the Kewl Tune Extra Deck monsters
• Turn 2 (going second): Hold hand traps (Ash Blossom, Effect Veiler, D.D. Crow, Ghost Ogre, Infinite Impermanence) to break the opponent's starter, then rebuild through Kewl Tune Synchro and Tuner recursion
• Recovery: Recover Tuners from the GY through the Kewl Tune Synchro and Mix effects, then re-Synchro; the deck has no non-Tuner bulk to recover a board on its own
• After siding: No Side Deck is registered, so there is no post-side plan; the list cannot adapt between games

Why it scores here

The deck reliably opens its Kewl Tune engine: the archetype core group has about 97% odds of at least one copy in a 5-card opening hand, and 16 searcher-text cards make a T1 search likely (Inferred, hypergeometric). Its ceiling is limited by a Tuner-dense main deck: 23 of 55 main cards are Tuners, so hands can fill with Tuners that have no non-Tuner partner to Synchro with, which pulls down the brick and median scores. Interaction is broad, with about 16 hand traps and 18 negation-text cards, which earns credit for going-second resilience, though no combo data exists to confirm a median output. The score is capped because the list is illegal: three Forbidden cards and four Limited cards are over their copy limits, so the result is structural-only. Popularity and archetype share earned no points, and card scores were not averaged into the deck score.

Dimension scores

How the score was computed

Strategy profile: Combo. Structural ≈ 55, Going First ≈ 58, Going Second ≈ 52, Meta = provisional, Tournament Reliability ≈ 40. Modifiers: banlist exposure (-8); engine conflicts / Tuner density (-4). Final formula: Illegal list: uncapped 0.80*Structural(55) + 0.20*TournamentReliability(40) + modifiers(-12) = 40; capped to 25 as theoretical/structural-only per legality guardrail

Probability & combo summary

• Opening a starter: P(≥1) ≈ 0.97 · key two-card combo ≈ — · full-brick estimate ≈ — (all Inferred)
• Combo output: best PowerIndex —, median —, board-per-starter —
• Turn order: 0 going-first lines vs 0 going-second lines

Strengths

• Archetype core is very likely to be present in an opening hand
• Layered hand-trap and negation coverage for going second
• Extra Deck is mostly flexible Synchro coverage

Weaknesses

• Illegal as built: three Forbidden cards and several Limited cards over copy limit
• Tuner-heavy main deck creates brick and redundancy risk
• No Side Deck, so no post-side adaptation

Critical choke points

• Kewl Tune Synchro and Mix searches are the main access route; losing them to a hand trap leaves few non-Tuner follow-ups

Recommended changes

Evidence & confidence

• Verified: Illegal status and six violations in legality; Forbidden status of three cards; Main 55, Extra 15, Side 0 counts; 23 Tuners in main deck (card list)
• Inferred: Archetype-core access ~0.97 at 5 cards; Brick and redundancy risk from Tuner density; Going-second hand-trap resilience; Going-first and going-second estimates
• Provisional: Meta Power and matchup fit (no dated meta sample); Tournament reliability (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 record absent No win-rate telemetry for going-first/second, matchup, or brick rate No Side Deck registered Meta Power is provisional without a dated metagame sample
