Kewl Tune Deck #772822 — Yu-Gi-Oh! OCG

Deck — Deck Power Evaluation

Final Contextual Deck Power: 30/100 (±10 · Confidence: Low)

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

Legality

Main 54 / Extra 16 / Side 0 — status under the rules at evaluation time: Illegal. 6 violation(s).

Identity & game plan

• Win condition: Synchro Summon Kewl Tune Extra Deck monsters (B2B, Loudness War, RS, Remix) off a Tuner-heavy main deck (Inferred from card text); Extra Deck closers such as Visas Amritara, Zalen and Super Starslayer TY-PHON - Sky Crisis (Inferred from card text)
• Turn 1 (going first): Normal Summon a Kewl Tune Tuner, use its search or Synchro-material text, then Synchro Summon into a Kewl Tune Synchro (Inferred)
• Turn 2 (going second): Hold hand traps (Ash Blossom, Effect Veiler, Ghost Ogre, Ghost Belle, Droll and Lock Bird) to negate the opponent's first play, then rebuild a Synchro (Inferred)
• Recovery: Recursion from the GY through Kewl Tune searchers and Ghost Belle banish/GY effects (Inferred from card text)
• After siding: None: the side deck is empty (Verified)

Why it scores here

This list is Illegal as built: five cards exceed their copy limits and the Extra Deck holds 16 cards against a maximum of 15, so it is scored as a theoretical, structural-only read and capped at 30. The Kewl Tune core (19 copies) gives roughly a 0.90 chance of at least one core card in the opening five, and the deck carries 14 hand-trap-role cards that give real going-second and interaction coverage. The main deck is saturated with Tuners (27 of 54 main cards), which makes Tuner-only hands and Synchro-material bricks a real risk, and there are no recorded boards, so the floor, median and ceiling of the combo output cannot be measured. Usage statistics show the archetype core is real and accessible, but that earned no points, and the score was built from the system's consistency, interaction and conversion read rather than from averaging individual card scores.

Dimension scores

How the score was computed

Strategy profile: Combo. Structural ≈ 49, Going First ≈ 46, Going Second ≈ 42, Meta = provisional, Tournament Reliability ≈ 40. Modifiers: banlist exposure (-8); engine conflict and Tuner saturation (-4). Final formula: 0.80*Structural(49) + 0.20*TournamentReliability(40) + modifiers(-12) = 35; capped to 30 because the list is Illegal (theoretical/structural-only). Meta Power provisional/null.

Probability & combo summary

• Opening a starter: P(≥1) ≈ 0.9 · key two-card combo ≈ — · full-brick estimate ≈ 0.1 (all Inferred)
• Combo output: best PowerIndex —, median —, board-per-starter —
• Turn order: 0 going-first lines vs 0 going-second lines

Strengths

• Kewl Tune core of 19 copies gives about a 0.90 chance of at least one core card in the opening 5 (Inferred)
• 14 hand-trap-role cards give broad negation coverage (Verified tags, Inferred semantics)
• Going-second hand-trap chance of about 0.85 in the opening 6 (Inferred)
• Extra Deck closers exist: Kewl Tune B2B, Loudness War, Visas Amritara (Verified card data)

Weaknesses

• Illegal list: five copy-limit violations and Extra Deck 16 over the maximum of 15 (Verified)
• Tuner saturation: 27 of 54 main cards are Tuners, with only 8 non-Tuner main monsters (Verified counts)
• No side deck, so no post-side plan (Verified)
• No recorded boards, so no measured floor or ceiling (Verified absence)

Critical choke points

• Kewl Tune Synchro and Reco chain: losing the core to hand traps stalls the Synchro route (Inferred)
• Extra Deck must be cut to 15 before the list is playable (Verified)

Recommended changes

Evidence & confidence

• Verified: Legality: five copy-limit violations and Extra Deck 16 over 15; Side deck is empty (0 cards); Main deck has 27 Tuner Monsters out of 54 cards; Core group P(>=1 in opening 5) = 0.8973 (hypergeometric)
• Inferred: Kewl Tune chain consistency; Brick and conflict risk from Tuner saturation; Interaction density from card text; Going-second hand-trap chance from hypergeometric estimate
• Provisional: Matchup and format fit, with no meta sample or tournament link
• 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 exists in YGOVN Meta Power is Provisional unless a dated metagame sample is supplied Deck is Illegal as built, so the score is theoretical and structural-only
