Kewl Tune Deck #769973 — Yu-Gi-Oh! OCG

Deck — Deck Power Evaluation

Final Contextual Deck Power: 54/100 (±7 · Confidence: Medium)

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

Legality

Main 55 / Extra 15 / Side 0 — status: Legal.

Identity & game plan

• Win condition: Synchro Summon a high-ATK or board-controlling Synchro (Chaos Angel, Kewl Tune B2B, Zalen, Visas Amritara, Malong) through Kewl Tune Mix / Kewl Tune Synchro / Kewl Tune Track Maker tuner-chain routes, with Kewl Tune Loudness War as a protected board anchor.; Hand-trap and negation-driven board control (Effect Veiler, Ash Blossom, Ghost Ogre, Ghost Belle, Infinite Impermanence, Maxx C, Solemn Judgment, Solemn Warning) that trades cards for the opponent's combo and then rebuilds through GY tuner recursion.
• Turn 1 (going first): Opening hand with a searcher (Kewl Tune Mix, JJ Kewl Tune, Kewl Tune Synchro, Duelist Genesis) to reach a Tuner, then Normal Summon or Special Summon a Tuner and Synchro Summon; keep one hand trap (Effect Veiler, Ash Blossom) for the opponent's first activation. Unverified without combo boards.
• Turn 2 (going second): Six-card hand with a hand trap (Ash Blossom, Ghost Ogre, Ghost Belle, Effect Veiler, Droll and Lock Bird) to answer the opponent's opening line, then convert the hand trap's discard into a Tuner-based Synchro Summon.
• Recovery: Recycle tuners from the GY through Kewl Tune Mix, Kewl Tune Reco, Kewl Tune Track Maker and Ghost Belle's GY-recovery effects; Kewl Tune Playlist and Over Tuning restore tuner access after a board wipe.
• After siding: No side deck is registered (side count 0), so there is no post-side plan in the evidence; the deck cannot adapt between games in a best-of-3 format.

Why it scores here

The deck reliably opens a Tuner-based starter: the searcher group (19 copies) has an estimated 0.89 chance of at least one copy in a 5-card opening hand, and the 16 archetype-core copies give 0.83 (Inferred from hypergeometric odds on the main deck). Its real strength is the interaction layer: 14 hand traps and 20 negation-text cards let it answer a combo on the way in, and the Kewl Tune Loudness War board anchor protects its tuners. Conversion and median output could not be measured because the export has no parseable boards, so the combo scores rest on card text and the Extra-Deck Synchro ceiling (Chaos Angel, B2B, Zalen) rather than on recorded results. The deck is held back by a 31% exact-archetype purity (48 off-archetype copies across PSY-Frame, Dominus, Blue-Eyes, Greed and Harpie), a zero-card side deck, and a high pilot burden. Popularity was not credited, and the score was not built by averaging card scores.

Dimension scores

How the score was computed

Strategy profile: Midrange. Structural ≈ 59.5, Going First ≈ 60, Going Second ≈ 63, Meta = provisional, Tournament Reliability ≈ 56. Modifiers: Banlist exposure (-2); Engine conflicts (-3). Final formula: 0.80*Structural (59.5) + 0.20*TournamentReliability (56) + ContextModifiers (-5) = 53.8, rounded to 54; Meta Power provisional (no dated metagame sample)

Probability & combo summary

• Opening a starter: P(≥1) ≈ 0.89 · 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

• Searcher density (19 copies, 0.89 chance of one in hand 5) gives an accessible starter.
• Layered interaction: 14 hand traps, 20 negation-text cards and two Solemn cards answer the opponent's line at several points.
• Tuner recursion through the GY (Kewl Tune Mix, Reco, Track Maker, Ghost Belle) gives a second route after disruption.
• The Extra Deck has high-ATK closers (Chaos Angel 3500, B2B 3200, Zalen 2800) that can finish a board.

Weaknesses

• No side deck at all (side 0): no adaptation across best-of-3 matches.
• Exact-archetype purity is 31.4%; 48 off-archetype copies across PSY-Frame, Dominus, Blue-Eyes, Greed and Harpie dilute the engine.
• Very high Tuner count (22 main) and many one-of starters raise brick and conflict risk in the opening hand.
• No recorded combos, so the floor and median are unmeasured.

Critical choke points

• Tuner access: most Synchro routes need a Tuner on the field or in the GY, so an opening hand without a searcher or tuner stalls.
• Going-second hand traps: a 6-card hand with no hand trap cannot answer the opponent's first line (0.16 chance of none, Inferred).

Recommended changes

Evidence & confidence

• Verified: Legality: Legal, 55 Main, 15 Extra, 0 Side; all Limited and Semi-Limited copy counts are within limits.; Archetype purity 31.4% (22 of 70 cards named Kewl Tune).; Card text, ATK/DEF and Extra-Deck monster stats as exported.; Usage statistics: Mulcharmy Fuwalos, Ash Blossom and Synchro Overtake show high inclusion (68.75%).
• Observed: Deck composition counts: 22 Tuner monsters, 14 hand traps, 15 Synchro monsters.
• Inferred: Opening-hand probabilities (0.89 searcher, 0.83 core, 0.84 hand trap going second) from hypergeometric odds on the Main Deck.; Interaction density, engine coherence and pilotability read from card text.
• Provisional: Meta Power and matchup coverage (no dated metagame or tournament link).; Post-side adaptation (no side deck to measure).
• Data gaps: No combos supplied: floor, median and ceiling are text-only inference (D3/D4 low confidence). No tournament link: archetype meta-share and per-pilot record absent; Meta Power provisional. No side deck (side count 0): D12 cannot be measured beyond structure. Evidence conflict: usage statistics marks Kewl Tune B2B, RS, Remix, Track Maker, Crackle, Loudness War and Zalen as not in this deck (in this deck false), but the cards array lists all of them in the Extra zone. The core-present percentage (56.2%) is therefore likely understated; the preprocessor appears to check Main only. No win-rate telemetry (going-first/second, matchup, brick/starter rates) exists in YGOVN.
