Kewl Tune Deck #772932 — Yu-Gi-Oh! OCG

Deck — Deck Power Evaluation

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

• Primary strategy: Midrange
• Secondary strategies: Stun, Combo
• Format: ocg

Legality

Main 55 / Extra 15 / Side 0 — status under the rules at evaluation time: Illegal. 7 violation(s).

Identity & game plan

• Win condition: Synchro summon high-ATK Kewl Tune Tuner bosses (Kewl Tune B2B, Loudness War, Remix) from a Tuner-heavy hand, using Kewl Tune searchers to rebuild the engine each turn.; Hand-trap and Synchro-tuned boards that protect a single boss through the opponent's interaction.
• Turn 1 (going first): Normal Summon a Kewl Tune Tuner (Mix/Cue/Clip), use its once-per-turn search into a second Tuner, then Synchro Summon a Kewl Tune boss from the Extra Deck while holding Ash Blossom or Ghost Belle for the opponent's response.
• Turn 2 (going second): Hold 18 hand traps (Ash Blossom, Ghost Ogre, Ghost Belle, Effect Veiler, Infinite Impermanence, Droll) to answer the opponent's first board, then rebuild the Kewl Tune engine from the GY.
• Recovery: Use GY-based revival and search effects (Kewl Tune Reco/Clip/Cue GY effects, Duelist Genesis, Synchro Overtake) to rebuild after a hand trap or board wipe.
• After siding: No side deck is registered, so there is no post-side plan. A legal version would need 15 side cards to answer Stun and Blind-Second matchups.

Why it scores here

This OCG list is illegal as submitted: 7 copy-limit violations, including 2 Forbidden cards (Called by the Grave, Triple Tactics Talent) and 3 Kewl Tune Limited cards run at 3 copies, so it receives a capped, structural-only score instead of a normal Final Contextual score. Structurally the Kewl Tune engine is reliable on paper, with P(at least one archetype core card in the opening 5) ≈ 0.81 and P(at least one searcher) ≈ 0.78 (Inferred). Its interaction density is high, with 18 hand traps and about 20 negation-text cards, which gives strong going-second resilience. The deck has no recorded boards, no tournament link and no side deck, so the floor, median and ceiling of its output are unmeasured and the score rests on text and probability inference. The score is built from consistency, interaction and Extra Deck coverage on the system as a whole, not from averaging card scores and not from Kewl Tune's popularity, which earned no points.

Dimension scores

How the score was computed

Strategy profile: Midrange. Structural ≈ 55, Going First ≈ 58, Going Second ≈ 60, Meta = provisional, Tournament Reliability ≈ 52. Modifiers: illegal-deck cap (-24). Final formula: Illegal cap: uncapped 0.80*Structural(55)+0.20*TournamentReliability(52) = 54, capped to 30 with a -24 legality modifier; Meta provisional

Probability & combo summary

• Opening a starter: P(≥1) ≈ 0.81 · 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 well represented (15 copies, P≈0.81 to open at least one)
• Dense interaction: 18 hand traps and about 20 negation-text cards
• Full Extra Deck with Synchro bosses that have high ATK and recursion

Weaknesses

• Illegal copy counts and two Forbidden cards
• No side deck
• No recorded combos or tournament data to verify output

Critical choke points

• Kewl Tune Tuner-chain starts depend on Tuners in hand; one hand trap or negation on the first Tuner can stall the line
• Hand-trap density lowers the number of starters per hand

Recommended changes

Evidence & confidence

• Verified: Copy-limit violations and banlist statuses (Called by the Grave, Triple Tactics Talent Forbidden); Main 55 / Extra 15 / Side 0 counts; Archetype core presence 15 copies; 13 Synchro + 2 Fusion in Extra Deck
• Inferred: P(≥1 starter in opening 5) ≈ 0.81 and P(≥1 searcher) ≈ 0.78 from hypergeometric estimates; Interaction density from card-text hints (18 hand traps, about 20 negation cards); Combo ceiling read from text, not recorded boards
• Provisional: Meta power and Matchup coverage (D13): no dated metagame or tournament link
• Data gaps: no combos supplied — combo floor/median/ceiling is text-only inference no tournament link — archetype meta-share and per-pilot match record absent no win-rate telemetry exists in YGOVN — brick/starter/OTK rates and matchup results are Inferred or Unknown Meta Power is provisional unless a dated metagame sample is supplied no side deck registered (side_count 0) deck title is null
