Kewl Tune Deck #770912 — Yu-Gi-Oh! OCG

Deck — Deck Power Evaluation

Final Contextual Deck Power: 54/100 (±6 · Confidence: Medium)

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

Legality

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

Identity & game plan

• Win condition: Synchro boards built from Kewl Tune Tuner-plus-non-Tuner summons, closed by Kewl Tune B2B (3200 ATK), Zalen, Enigmaster Packbit and Golden Cloud Beast - Malong.; Hand traps and Solemn/Mind Mirror Force interaction protect the engine long enough to reach the Synchro board.
• Turn 1 (going first): Normal Summon Kewl Tune Mix, use its search on a Kewl Tune monster, then Synchro into a boss while keeping Ash Blossom, Effect Veiler or Infinite Impermanence in hand for the opponent's first response.
• Turn 2 (going second): Hold hand traps (Nibiru, Ghost Ogre, Effect Veiler, Ash Blossom, Infinite Impermanence) to answer the opponent's first summon or Spell/Trap, then rebuild through Kewl Tune recursion and the Extra Deck.
• Recovery: Recover Tuners from the GY through Kewl Tune Reco, Clip and Rotary effects, then re-Synchro through Kewl Tune RS or Track Maker, which can be summoned with a Tuner in the GY.
• After siding: Not evaluable: the list runs 0 side cards, so there is no post-side plan; any sideboarding would have to be added to the list.

Why it scores here

The deck reliably opens a Kewl Tune Synchro plan through its Tuner-heavy main deck: Kewl Tune Mix, Duelist Genesis and JJ Kewl Tune give several independent starters, and the archetype core group has about a 78% chance of at least one copy in a 5-card opening hand (Inferred). Its conversion ceiling sits in the 15-card all-Synchro Extra Deck, which reaches 2800-3200 ATK boards, but no recorded boards exist, so the ceiling is text-based (Inferred). Interaction is the strongest part of the system: 17 hand traps, 3 Solemn-family traps, and Mind Mirror Force give high end-board and going-second coverage, with a 90% chance of at least one hand trap in a 6-card going-second hand (Inferred). The deck loses points for a 55-card main deck with only 28.6% exact-archetype purity, Mulcharmy cards that conflict with a board-based engine, and having no side deck at all. The score comes from consistency, interaction and Extra Deck coverage evaluated on the system, not from averaging card scores, and the deck's usage-statistics presence and archetype popularity did not add points.

Dimension scores

How the score was computed

Strategy profile: 70/30. Structural ≈ 61, Going First ≈ 66, Going Second ≈ 64, Meta = provisional, Tournament Reliability ≈ 53. Modifiers: banlist exposure (-2); engine conflict (-3). Final formula: 0.80*Structural + 0.20*TournamentReliability + ContextModifiers (Meta provisional; no dated metagame sample)

Probability & combo summary

• Opening a starter: P(≥1) ≈ 0.78 · 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

• Deep starter set: Kewl Tune Mix x3, JJ Kewl Tune x2, Duelist Genesis x3 and Synchro Overtake give several independent openers.
• Interaction density is high: 17 hand traps plus Solemn x3 and Mind Mirror Force cover both turns.
• Extra Deck is fully Synchro with a spread of levels and strong 2800-3200 ATK bosses.

Weaknesses

• No side deck: no post-side adaptation at all.
• Only 28.6% of the 70 cards carry the exact Kewl Tune name; Mulcharmy, PSY-Frame, Blue-Eyes and Earthbound cards split the engine.
• A 55-card main deck is heavy; 17 hand traps risk dead cards when the opponent does not interact.

Critical choke points

• Kewl Tune Mix and the Tuner count in hand: without a Tuner, the Synchro plan does not start.
• Single-copy Limited cards (Cue, Reco, Rotary, Synchro) have no redundant copies if removed or hit by a banlist change.

Evidence & confidence

• Verified: Legal under OCG BanList: 55 main, 15 extra, 0 side, all restricted copies within limits; Card text and stats for all 70 cards; Archetype purity: 20 of 70 cards carry the exact Kewl Tune name; Copy histogram and Extra Deck breakdown (15 Synchro)
• Observed: Usage statistics show 7 of 12 core Kewl Tune cards present (58.3%)
• Inferred: Starter access: P(>=1 archetype-core copy in 5 cards) = 0.78; Going-second hand-trap coverage: 0.90 per 6-card hand; Interaction density and end-board quality from text reads; Engine conflict from Mulcharmy's empty-field requirement; Structural 61, going-first 66, going-second 64
• Provisional: Meta Power (no dated metagame sample); D13 matchup and format fit (no tournament share)
• Data gaps: no combos supplied: combo floor, median and ceiling are text-only inference no tournament link: archetype meta-share and per-pilot match record absent no win-rate telemetry (going-first/second, matchup, brick/starter rates) — those signals are Inferred or Unknown Meta Power is Provisional unless a dated metagame sample is supplied Zero side deck cards in the export: post-side evaluation is not possible
