Kewl Tune Deck #751289 — Yu-Gi-Oh! TCG

Deck — Deck Power Evaluation

Final Contextual Deck Power: 38/100 (±8 · Confidence: Low)

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

Legality

Main 55 / Extra 15 / Side 0 — status under the rules at evaluation time: Illegal. 11 violation(s).

Identity & game plan

• Win condition: Synchro chains off Kewl Tune Tuners into Extra-Deck boards such as Kewl Tune B2B (3200 ATK) and Kewl Tune Loudness War (Inferred from card text); Fusion boards (Garura, Mudragon, Sea Monster of Theseus) as a non-Synchro follow-up (Inferred)
• Turn 1 (going first): Normal Summon a Kewl Tune Tuner, search a Kewl Tune card or Synchro Spell, and Synchro Summon through the Tuner chain (Inferred)
• Turn 2 (going second): Use hand traps (Ash Blossom, Effect Veiler, Infinite Impermanence, Ghost Ogre) to answer the opponent's first board, then rebuild through Kewl Tune recursion (Inferred)
• Recovery: Recover Tuners from the GY through Kewl Tune Reco, Mix and Cue effects, then re-Synchro (Inferred)
• After siding: No side deck, so no post-side plan exists (Verified)

Why it scores here

This list is Illegal (five Forbidden cards and several over-limit copies), so it receives only a theoretical, structural-only read capped low, and the final score is not a normal contextual score. Its strongest system feature is the Kewl Tune Tuner web, which keeps a Tuner in hand or GY for most openers (archetype-core group P(at least one Kewl Tune in opening 5) about 0.97, Inferred) and gives several recursion routes after disruption. Interaction is dense, with 15 hand-trap-tagged copies and Solemn Judgment, which lifts going-second resilience. Consistency is held back by 45 off-archetype copies out of 70 archetype-tagged copies, 24 tech slots, and no side deck. No recorded boards exist, so median output and ceiling are text-only inference and are not measured. Popularity and archetype usage confirm the list is real and accessible, but they earned no points, and card scores were not averaged into the deck score.

Dimension scores

How the score was computed

Strategy profile: Combo. Structural ≈ 53.6, Going First ≈ 55, Going Second ≈ 45, Meta = provisional, Tournament Reliability ≈ 35. Modifiers: banlist_exposure (-12). Final formula: 0.80*Structural + 0.20*TournamentReliability + banlist modifier (-12) = 0.8*53.6 + 0.2*35 - 12 = 37.9, rounded to 38; Meta provisional; Illegal list so structural-only theoretical read

Probability & combo summary

• Opening a starter: P(≥1) ≈ — · 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

• Archetype-core Tuners are present at full copies, so the engine opens often (Inferred)
• Dense hand-trap and negation density gives several answers to a going-second board (Inferred)
• Recursion routes via Tuners in GY reduce single-choke-point risk (Inferred)

Weaknesses

• Illegal list: five Forbidden cards and several over-limit copies must be cut before any real rating applies (Verified)
• Only about 36 percent exact-archetype purity; 45 off-archetype copies and 24 tech slots dilute the opener (Verified)
• No side deck, so no post-side adaptation (Verified)
• No recorded boards, so combo floor and ceiling are unmeasured (Verified)

Critical choke points

• Kewl Tune Tuner in hand or GY for every Synchro line (Inferred)
• Legal copy count of Kewl Tune Cue, Reco and Synchro (1 each) once the list is corrected (Verified)

Recommended changes

Evidence & confidence

• Verified: Main 55, Extra 15, Side 0 counts within TCG size rules; Five Forbidden cards and several copy-limit violations listed in legality; Archetype purity 35.7 percent (25 of 70 archetype-tagged copies); Side deck empty
• Inferred: Engine accessibility from hypergeometric odds; Hand-trap and recursion resilience from card text; Going-first and going-second estimates from card text and probabilities
• Provisional: Meta Power and matchup fit (no dated metagame sample); Median output and floor (no recorded boards)
• 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; going-first/second, matchup and brick rates are Inferred or Unknown Meta Power is Provisional unless a dated metagame sample is supplied usage_statistics marks Kewl Tune Loudness War, Track Maker, RS, Remix and B2B as in_this_deck:false, but the cards array lists them in the Extra Deck with copies 1-2; the usage match appears to skip Extra-Deck cards, so the missing_core list is not trusted Deck title is null; identified by archetype only
