Kewl Tune Deck #770015 — Yu-Gi-Oh! OCG

Deck — Deck Power Evaluation

Final Contextual Deck Power: 57/100 (±8 · Confidence: Medium)

• Primary strategy: Combo
• Secondary strategies: Stun, Synchro, Link
• Format: ocg

Legality

Main 42 / Extra 15 / Side 0 — status: Legal.

Identity & game plan

• Win condition: Synchro and Link summons of large Kewl Tune and Evil Twin monsters (B2B 3200 ATK, Evil Twin's Trouble Sunny 3300 ATK, A Bao A Qu 2800 ATK, Zalen 2800 ATK), reached through Kewl Tune Tuner chains from the hand; Hand-trap-supported Tuner chains that stall the opponent's Synchro or Link lines and then convert the board with Link Monsters
• Turn 1 (going first): Normal Summon a Kewl Tune Tuner (Mix, Clip, Rotary, Cue or Reco), search the next Kewl Tune or Live Twin piece, then Synchro or Link Summon toward the Extra Deck threat
• Turn 2 (going second): Hold Effect Veiler, Ash Blossom, Ghost Belle, Infinite Impermanence and Droll & Lock Bird for the opponent's turn to slow the first line, then rebuild through Tuner recursion and GY effects
• Recovery: Search with Mix, Reco, Track Maker or Synchro, recover Tuners from the GY through Ghost Ogre and Ghost Belle, and re-run Synchro summons from the remaining Extra Deck pieces
• After siding: None. The deck has 0 side cards, so there is no post-side plan to evaluate.

Why it scores here

The deck reliably opens a live engine: the 13-copy Kewl Tune core has an estimated 86% chance of at least one card in a 5-card opening hand, and 20 searcher-text cards keep the Tuner chain supplied. Its interaction is the strongest part of the system, with 13 hand traps and 10 negation or removal texts giving high chances to answer a line on the opponent's turn. Recovery comes from GY Tuner recursion and searchers, so the deck can rebuild after an interruption. The score is not driven by Kewl Tune's popularity or by averaging card scores. The ceiling and median output are not measured, because no combos were supplied, and the zero side deck and the split between two Tuner engines pull the score down.

Dimension scores

How the score was computed

Strategy profile: 70% Combo / 30% Stun (hybrid; D13 dropped and renormalised for the meta-neutral Structural score, over 93.7 total weight). Structural ≈ 66, Going First ≈ 66, Going Second ≈ 70, Meta = provisional, Tournament Reliability ≈ 52. Modifiers: banlist exposure (-2); weak post-side plan (-2); engine conflicts (-2). Final formula: 0.80*Structural + 0.20*TournamentReliability + ContextModifiers (no dated metagame; Meta provisional). Structural = 66.15 (meta-neutral, D13 dropped); TR = 52 (mean of D1/D2 ≈ 74, D5 66, D12 20, D14 40, D6 62 as a simple average of the components); 0.80*66.15 + 0.20*52 = 63.3; modifiers -6 gives 57.3, rounded to 57

Probability & combo summary

• Opening a starter: P(≥1) ≈ 0.86 · key two-card combo ≈ — · full-brick estimate ≈ 0.14 (all Inferred)
• Combo output: best PowerIndex —, median —, board-per-starter —
• Turn order: 0 going-first lines vs 0 going-second lines

Strengths

• Strong starter access: 13-copy archetype core with about 86% opening-hand presence and 20 searcher-text cards
• Layered interaction: 13 hand traps, 10 negation texts, 18 removal texts and Loudness War's Tuner protection
• Extra Deck coverage: 10 Synchro and 5 Link, with 7 Kewl Tune Synchro Tuners for flexible summons
• Recovery via GY Tuner recursion (Ghost Ogre, Ghost Belle, Mix, Reco, Track Maker)

Weaknesses

• No side deck: nothing to adapt with across best-of-3 rounds
• Two Tuner engines (Kewl Tune and Live Twin/Evil Twin) with 35% exact-name purity: the lines compete for hand and Normal Summons
• Nine Limited cards and Ash at Semi-Limited sit at their copy limits, so the list has no slack
• No recorded boards, so the combo floor and median cannot be checked against the ceiling

Critical choke points

• The first Tuner or the first Synchro/Link starter: losing it to an opposing hand trap or negation leaves the hand with off-archetype pieces
• Normal Summon economy: Kewl Tune Mix, Clip, Rotary, Reco and Assault Synchron all compete for one Normal Summon per turn

Evidence & confidence

• Verified: Legality: Legal in OCG; 42 Main (40-60), 15 Extra (0-15), 0 Side (0-15); no copy-limit violations; Banlist: nine Limited copies at their limit and Ash Blossom at Semi-Limited with 2 copies; Composition: 24 distinct Main, 13 distinct Extra, 10 Synchro and 5 Link Extra cards; Usage: Kewl Tune core cards appear in the usage statistics with 50-75% inclusion
• Inferred: Opening-hand consistency: 0.86 for the archetype core, 0.97 for searchers, 0.91 for hand traps (going-second); hypergeometric; Interaction layering from card text (13 hand traps, 10 negation texts); Recovery and resource economy from GY recursion text; Ceiling from card-text stats (B2B 3200, Sunny's Trouble 3300); not from recorded boards
• Provisional: Meta power and matchup fit (no dated metagame sample supplied); Tournament reliability inputs that depend on post-side data, which does not exist
• Data gaps: No combos supplied: combo floor, median and ceiling are text-only inference No side deck: post-side adaptability cannot be assessed No tournament link: archetype meta-share and per-pilot match record absent No win-rate telemetry: going-first/second, matchup and brick/starter rates are Inferred or Unknown Meta Power is Provisional unless a dated metagame sample is supplied Deck title is null
