Kewl Tune Deck #772537 — Yu-Gi-Oh! OCG

Deck — Deck Power Evaluation

Final Contextual Deck Power: 30/100 (±8 · Confidence: Low)

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

Legality

Main 55 / Extra 15 / Side 0 — status under the rules at evaluation time: Illegal. 8 violation(s).

Identity & game plan

• Win condition: Synchro Summon Kewl Tune boss monsters (Loudness War, B2B, Chaos Angel, TY-PHON) off Tuner-heavy openings and convert the board with Kewl Tune Synchro and Mix/Reco searches; Hand-trap and negation-driven interaction (Ash Blossom, Infinite Impermanence, Effect Veiler, Droll & Lock Bird) that protects the Synchro board until it can attack
• Turn 1 (going first): Normal Summon Kewl Tune Cue or Rotary, search or Special Summon a second Tuner through Reco, Mix or Clip, then Synchro Summon a boss; hold Impermanence or Ash for the first opposing response
• Turn 2 (going second): Open with a hand trap (Ash, Veiler, Ghost Belle, Impermanence) on the opponent's starter, then rebuild the Tuner board from the GY and Synchro Summon through the remaining hand
• Recovery: Recurse Tuners from the GY through Kewl Tune Mix, Reco and Track Maker effects and reuse Kewl Tune Synchro to search the next engine piece
• After siding: Not evaluable: side deck is empty (0 cards), so there is no post-side plan in the list as submitted

Why it scores here

The deck's reliable opening is its Kewl Tune core: 20 core copies give about a 91% chance of at least one in a 5-card opening hand, and that is the main reason its engine score is in the upper range. Its structural strength comes from a dense interaction package (about 14 hand traps, 20 negation effects and 24 removal effects) that keeps a Synchro board alive, and the Extra Deck supplies several bosses. Its weaknesses are a large share of off-archetype tuners and spells (purity about 36% by exact name) that dilute the engine, and the list has no side deck, so it has no post-side plan. The rules violations are the main drag: 8 cards exceed their legal copy limits, including 2 Forbidden cards, so this list is not a playable build and only its theoretical structure is evaluated. Popularity and archetype usage were not credited, and card scores were not averaged; no recorded combo boards exist, so the combo and floor scores are text-based inference.

Dimension scores

How the score was computed

Strategy profile: Combo profile only; secondary strategy noted in identity but not blended. Structural ≈ 59, Going First ≈ 58, Going Second ≈ 62, Meta = provisional, Tournament Reliability ≈ 52. Modifiers: banlist exposure (-8); engine conflicts (-4); no Side Deck (-3); illegal_list_cap (-16). Final formula: Theoretical 0.80*Structural(59) + 0.20*TournamentReliability(52) + modifiers(-12) = ~46; capped to 30 because the list is Illegal (8 copy-limit violations, 2 Forbidden cards). Meta Power null (provisional).

Probability & combo summary

• Opening a starter: P(≥1) ≈ 0.91 · key two-card combo ≈ — · full-brick estimate ≈ 0.09 (all Inferred)
• Combo output: best PowerIndex —, median —, board-per-starter —
• Turn order: 0 going-first lines vs 0 going-second lines

Strengths

• Large Kewl Tune core (20 copies) gives about 91% starter access in a 5-card opening
• Dense interaction: about 14 hand traps, 20 negation texts and 24 removal texts
• Multiple Synchro bosses and search tools in the Extra Deck

Weaknesses

• Illegal list: 8 copy-limit violations including 2 Forbidden cards
• Low exact-name purity (35.7%) with many off-archetype tuners and spells
• No side deck, so no post-side adaptability
• No recorded boards, so the combo floor and median are unknown

Critical choke points

• Kewl Tune Cue, Rotary, Reco, Synchro, Droll and Ash must be cut to legal counts before the deck can be played as listed
• Heavy dependence on Tuner-in-hand Normal Summons; a hand without a Tuner stalls the engine

Recommended changes

Evidence & confidence

• Verified: Legality violations and banlist statuses from evidence; Main 55 and Extra 15 counts; Card text and stats for listed cards; Hypergeometric probabilities (0.2529 per 3-copy card; 0.9067 core group)
• Inferred: Starter and engine consistency; Brick risk and redundancy; Interaction quality from text; Going-second hand-trap coverage
• Provisional: Meta and matchup fit (no dated meta sample)
• Data gaps: No combos supplied: combo floor, median and ceiling are text-only inference No tournament link: archetype meta-share and pilot record absent No win-rate telemetry exists in YGOVN Usage-stat matching disagrees with the card list: Kewl Tune RS, Remix, Crackle and B2B appear in the Extra Deck zone but are marked not in deck, so core-present percentage is unreliable Deck title is null, so the deck is identified by archetype only No side deck, so post-side performance is unknown
