Kewl Tune Deck #751387 — Yu-Gi-Oh! TCG

Deck — Deck Power Evaluation

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

• Primary strategy: Combo
• Secondary strategies: Toolbox
• Format: tcg

Legality

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

Identity & game plan

• Win condition: Synchro Summon of Kewl Tune Extra Deck monsters (Loudness War, Track Maker, RS, Remix, B2B) and Chaos Angel / Zalen for pressure; Tuner-chain board presence with Ecclesia and Visas Amritara as follow-up threats
• Turn 1 (going first): Normal Summon a Kewl Tune Tuner, use its search to add a Kewl Tune Tuner, then Synchro Summon a Kewl Tune Synchro monster
• Turn 2 (going second): Use hand traps (Ash Blossom, Ghost Belle, Effect Veiler, D.D. Crow, Ghost Ogre) to break the opponent's starter, then rebuild through Kewl Tune Mix/Reco searches
• Recovery: Recover from the GY through Kewl Tune Mix and Reco searches and Track Maker and B2B GY effects, which are text-based and unverified in practice
• After siding: Not evaluable: the side deck is empty (side_count 0); no post-side plan exists in the evidence

Why it scores here

The deck is Illegal as built: six cards exceed their copy or banlist limits and the Side Deck is empty, so this score is theoretical and structural only and is capped at 25. The engine is dense: 23 Tuners plus 12 Synchro Tuners, with three-copy Kewl Tune Mix, Cue and Reco giving about a 25% chance of at least one per opening 5-card hand (Inferred), and the archetype core group is about 98% likely to appear in an opening hand (Inferred). Interaction is broad, with 16 hand traps and 18 negation-text cards, which earns the going-second and end-board dimensions. Consistency and the median output are held back by a 37% exact-name archetype purity, 44 off-archetype copies, and no recorded combo boards to confirm what the deck actually does. No points were given for Kewl Tune popularity, and no card scores were averaged into the deck score.

Dimension scores

How the score was computed

Strategy profile: Combo. Structural ≈ 55, Going First ≈ 55, Going Second ≈ 60, Meta = provisional, Tournament Reliability ≈ 50. Modifiers: Banlist exposure (-8); Archetype purity / engine conflicts (-4). Final formula: No-meta formula: 0.80*Structural(55) + 0.20*TournamentReliability(50) + modifiers(-12) = 42, then capped at 25 because the list is Illegal (theoretical only)

Probability & combo summary

• Opening a starter: P(≥1) ≈ 0.98 · 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

• Dense Tuner engine with redundant starters (Mix, Cue, Reco at 3 copies each) (Inferred)
• Broad hand-trap and negation coverage (16 hand traps, 18 negation-text cards) (Inferred)
• Full Extra Deck of Kewl Tune Synchros with strong closers (Verified composition)

Weaknesses

• Illegal as built: six copy or banlist violations (Verified)
• Empty Side Deck, so no best-of-3 adaptation (Verified)
• Low archetype purity (37.1%) and 44 off-archetype copies, which weakens engine coherence (Verified composition)
• No combo boards or win telemetry to confirm the ceiling or median (Verified gap)

Critical choke points

• Kewl Tune Mix, Cue and Reco are the main starters, and their Limited copy caps make the engine fragile once the list is legal
• Albion (Forbidden) is the only Fusion Extra Deck card, so its removal needs no replacement

Recommended changes

Evidence & confidence

• Verified: Six legality violations and their banlist statuses; Copy histogram and type/attribute spread; Core usage: 13 of 18 core cards present; Empty side deck (side_count 0)
• Inferred: Starter hypergeometric consistency (about 0.25 per 3-copy card, 0.98 for the core group); Interaction density and going-second hand-trap coverage; Structural dimension scores D1-D14 (except D13); Combo ceiling and floor from card text only
• Provisional: Meta Power (null); D13 matchup and format fit (no dated meta)
• Data gaps: No combo boards supplied; combo floor, median and ceiling are text-only inference No tournament link; archetype meta-share and per-pilot record are absent No win-rate telemetry; going-first and going-second splits are Inferred Side deck is empty, so no post-side evaluation is possible Meta Power is Provisional without a dated metagame sample
