Kewl Tune Deck #751808 — Yu-Gi-Oh! TCG

Deck — Deck Power Evaluation

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

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

Legality

Main 55 / Extra 15 / Side 0 — status: Illegal. 9 violation(s).

Identity & game plan

• Win condition: Synchro summons of Kewl Tune and Tuner-based Synchro monsters (Kewl Tune B2B, Chaos Angel, TY-PHON, Malong) that overwhelm the board, backed by hand-trap protection; Stun-style disruption: 17 hand traps and 24 removal/negation-text cards that stall the opponent's combo while the Kewl Tune engine develops
• Turn 1 (going first): Normal Summon Kewl Tune Cue or Reco to search or special summon a second Tuner, then Synchro Summon a Kewl Tune Synchro-tier monster and set up Kewl Tune Synchro for a follow-up Tuner
• Turn 2 (going second): Hold Ash Blossom, Infinite Impermanence, Effect Veiler, Ghost Belle and Ghost Ogre to answer the opponent's first board, then Synchro through the remaining Tuners
• Recovery: Rebuild from the GY with Kewl Tune Reco, Kewl Tune Mix and Kewl Tune Playlist recursion, and Mulcharmy draw effects to refill the hand
• After siding: Not evaluable: the export lists no side deck, so no post-side plan exists in the evidence

Why it scores here

The list is structurally coherent around Kewl Tune: about 98% of 55 main-deck slots include at least one archetype-core card in a 5-card opening hand, and the Synchro Extra Deck (13 Synchro, 1 Link, 1 XYZ) gives many finishing options. Interaction is dense (17 hand traps, 17 negation-text cards, 24 removal-text cards), which lifts the going-second and interruption-resilience reads. The score is held down by brick risk from a 27-Tuner main deck, the absence of any recorded boards so the floor and median are inferred from text only, and no side deck. The list is Illegal under TCG rules: four Forbidden cards and several Limited and Semi-Limited copies exceed their limits, so the result is a theoretical, structural-only read and is capped at 30. Popularity (the archetype core is standard) and card-by-card power were not averaged into the score; the score reflects how the system operates.

Dimension scores

How the score was computed

Strategy profile: Combo. Structural ≈ 55.4, Going First ≈ 60, Going Second ≈ 58, Meta = provisional, Tournament Reliability ≈ 45. Modifiers: Banlist exposure (-6); No side deck / no post-side plan (-4). Final formula: No reliable metagame: 0.80*Structural(55.4) + 0.20*TournamentReliability(45) = 53.4; plus modifiers (-10) = 43.4; capped at 30 because legality is Illegal (theoretical/structural-only read, per rubric Step 2)

Probability & combo summary

• Opening a starter: P(≥1) ≈ 0.25 · 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 is present in almost every opening hand (≈98% at least one core card in 5 cards)
• Dense interaction package: 17 hand traps and 24 removal/negation-text cards
• Extra Deck gives a broad Synchro finisher suite (TY-PHON, Chaos Angel, B2B, Malong)
• Strong going-second response: ≈90% chance of at least one hand trap in a 6-card hand

Weaknesses

• Illegal as built: four Forbidden cards and multiple Limited and Semi-Limited copies over the limit
• Tuner-heavy main deck (27 Tuners) raises the risk of dead or conflicting hands
• No side deck, so no post-side adaptability
• No recorded combo boards, so the floor and median cannot be measured

Critical choke points

• Kewl Tune Cue, Reco and Synchro each have one legal copy, so the engine loses redundancy once the list is legalized
• Ash Blossom and the other hand traps must all be drawn to protect the first Synchro; interruption resilience depends on them
• The Forbidden Kewl Tune Rotary is a Tuner and searcher in the main deck; removing it reduces the Tuner count and changes the core lines

Recommended changes

Evidence & confidence

• Verified: Main deck is 55 cards and Extra deck is 15 cards, both within TCG size rules; The list is Illegal: 4 Forbidden cards and 9 copy-limit violations; Archetype core group P(≥1 in opening hand) = 0.9768; Side deck count is 0
• Inferred: Consistency and brick estimates from hypergeometric draw odds; Hand-trap and interruption resilience from card text; Going-second board breaking from hand-trap density
• Provisional: Meta Power and matchup fit: no dated metagame sample or tournament link; Post-side adaptability: no side deck
• Data gaps: No combos supplied, so combo floor, median and ceiling are text-only inference No tournament link, so archetype meta-share and per-pilot records are absent No win-rate telemetry exists for this deck No side deck in the export, so post-side plan cannot be assessed Meta Power is provisional without a dated metagame sample
