Kewl Tune Deck #751334 — Yu-Gi-Oh! TCG

Deck — Deck Power Evaluation

Final Contextual Deck Power: 35/100 (±8 · Confidence: Medium)

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

Legality

Main 55 / Extra 15 / Side 0 — status: Illegal. 8 violation(s).

Identity & game plan

• Win condition: Synchro Summon high-ATK Kewl Tune and K9/Visas/Black Rose boss monsters (e.g. Kewl Tune B2B 3200 ATK, Super Starslayer TY-PHON 2900 ATK) from a tuner-heavy Main Deck engine.; Hand-trap and removal pressure (Ash Blossom, Ghost Ogre, Ghost Belle, Effect Veiler, Droll & Lock Bird, Solemn Judgment, Harpie's Feather Duster, Lightning Storm) to keep the opponent from converting their own turn.
• Turn 1 (going first): Normal Summon a Kewl Tune tuner (Cue, Mix, Reco) to search or Special Summon another Tuner, then Synchro Summon into a Kewl Tune Synchro Tuner from the Extra Deck, using Kewl Tune Synchro or JJ "Kewl Tune" for extra summons.
• Turn 2 (going second): Hold Ash Blossom, Ghost Ogre & Snow Rabbit, Ghost Belle & Haunted Mansion or Effect Veiler to negate or destroy the opponent's first engine card, then rebuild a Synchro board from the GY tuners.
• Recovery: Recover tuners from the GY through Kewl Tune Mix and Kewl Tune Reco effects and Kewl Tune Playlist, then re-Synchro through the Extra Deck.
• After siding: No side deck is registered, so there is no post-side plan; the deck is evaluated on its Main Deck only.

Why it scores here

The score reflects the deck as a system, not an average of its cards. The Kewl Tune core (28 copies, P(at least one in a 5-card opening hand) ≈ 0.98, Inferred) gives a reliable Synchro engine, and 14 hand traps plus 15 negation/removal texts give it strong interaction against the opponent's first turn. Conversion ceiling and median output could not be measured because no recorded boards exist, so those scores are structural reads only. The deck is Illegal: 8 copy-limit violations, including a Forbidden Kewl Tune Rotary and Forbidden Called by the Grave, and no side deck. Under the rubric the structural score (about 61) plus a banlist-exposure modifier gives about 47 before the cap; the Illegal cap reduces the reported score to 35, and this is a theoretical, structural-only read. Popularity and archetype usage did not add points, and no card scores were averaged.

Dimension scores

How the score was computed

Strategy profile: Combo primary; Stun secondary for interaction density (no ratio applied; profile weights used as-is). Structural ≈ 61, Going First ≈ 60, Going Second ≈ 66, Meta = provisional, Tournament Reliability ≈ 50. Modifiers: Banlist exposure (-8); Copy-limit overage (-3); Off-archetype dilution (-1); Illegal cap (-12). Final formula: No reliable metagame: 0.80*Structural(61) + 0.20*TournamentReliability(50) = 58.8; modifiers -12 (clamped) → 46.8; Illegal cap applied → 35 (theoretical, structural-only)

Probability & combo summary

• Opening a starter: P(≥1) ≈ 0.98 · 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

• Large archetype-core density (28 copies) gives a high probability of a starter in hand
• 14 hand traps and 15 negation texts provide interaction on both turns
• Full 15-card Extra Deck with multiple Synchro access routes

Weaknesses

• Illegal list: copy-limit violations and a Forbidden Kewl Tune Rotary and Called by the Grave
• No side deck registered, so no post-side adaptability
• Only 38.6% exact-name archetype purity; many off-archetype copies dilute the engine

Critical choke points

• Kewl Tune Rotary is Forbidden and must be removed before any legal list exists
• Tuner-count dependence on Kewl Tune Cue/Mix/Reco; losing several tuners to hand traps slows the Synchro line

Recommended changes

Evidence & confidence

• Verified: Legality: Illegal, 8 copy-limit violations, Forbidden Kewl Tune Rotary and Called by the Grave; Main 55 / Extra 15 / Side 0 counts; Archetype purity 38.6% exact-name; Extra Deck breakdown 12 Synchro / 3 Xyz
• Observed: No recorded combo boards; combo observations not available
• Inferred: Starter access ≈ 0.98 for archetype-core group (hypergeometric); Hand-trap going-second probability ≈ 0.84; Interaction and resilience scores from card text; Synchro conversion and closing power from card text
• Provisional: Meta Power (no dated sample); Format fit (no tournament link)
• Data gaps: No combos supplied; combo floor/median/ceiling is text-only inference No tournament link; archetype meta-share and per-pilot record absent No win-rate telemetry; going-first/second, matchup and brick rates are Inferred or Unknown No side deck registered usage_statistics in_this_deck flags disagree with the cards array for Kewl Tune Loudness War (41069676), Kewl Tune Track Maker (42781164), Kewl Tune Remix (88170262), Kewl Tune RS (15665977) and Kewl Tune B2B (65961304): cards list them with copies >0 while usage marks them absent; the cards array was treated as truth Meta Power provisional unless a dated sample is supplied
