Kewl Tune Deck #765011 — Yu-Gi-Oh! Master Duel

Deck — Deck Power Evaluation

Final Contextual Deck Power: 70/100 (±6 · Confidence: Medium)

• Primary strategy: Midrange
• Secondary strategies: Stun
• Format: master-duel

Legality

Main 40 / Extra 15 / Side 0 — status: Legal.

Identity & game plan

• Win condition: Synchro Summon Kewl Tune Remix, Loudness War, Track Maker or B2B off a Kewl Tune Tuner starter, then attack through a board protected by hand traps; Kewl Tune Crackle / Malong / Ignister Pegasus Synchro pressure and Albion or TY-PHON Extra Deck follow-ups
• Turn 1 (going first): Turn 1 Normal Summon a Tuner (Kewl Tune Mix, Reco, Cue or Rotary) or search via JJ / Duelist Genesis, then Synchro Summon the Kewl Tune Synchro line; hold Ash Blossom and Ghost Belle for the opponent's Main Phase
• Turn 2 (going second): Hand traps first (Ash Blossom, Ghost Ogre, Ghost Belle, Effect Veiler, Maxx C, Fydraulis Harmonia) to answer the opponent's board, then rebuild the Synchro line on the following turn
• Recovery: Kewl Tune Mix / Reco and Synchro search effects recover a Tuner and a Kewl Tune card from Deck or GY; Earthbound Prisoner Stone Sweeper searches a Level 3 or lower Fiend Tuner
• After siding: Not applicable: Master Duel has no sideboard (side_count 0). No post-side plan exists to evaluate.

Why it scores here

The deck opens a live engine reliably: the Kewl Tune core is 24 copies across 24 distinct names in the Main and Extra Decks, and the hypergeometric estimate gives P(at least one archetype core card in a 5-card opening hand) of about 0.99, with P(at least one searcher-text card) about 0.95 (Inferred). Its 10 hand traps (Ash Blossom, Ghost Ogre, Ghost Belle, Effect Veiler, Maxx C, Fydraulis Harmonia and others) give it real interruption resilience and going-second interaction, with about 0.85 odds of at least one hand trap in a 6-card going-second hand (Inferred). Ceiling is supported only by card text and guide snippets (Loudness War, Remix, B2B), not by recorded boards, so it is marked Inferred and kept below the consistency read. Median output and matchup fit are not measured, so they are held near neutral. The score comes from consistency, interaction and system-level redundancy, not from Kewl Tune's popularity or from averaging individual card scores.

Dimension scores

How the score was computed

Strategy profile: Midrange. Structural ≈ 72, Going First ≈ 73, Going Second ≈ 74, Meta = provisional, Tournament Reliability ≈ 67. Modifiers: banlist_exposure (-2); engine_conflicts (-1); engine_compactness (2). Final formula: 0.80*Structural + 0.20*TournamentReliability (Meta provisional); Structural computed meta-neutral with D13 dropped and weights renormalised to 95

Probability & combo summary

• Opening a starter: P(≥1) ≈ 0.34 · 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

• Core engine over-saturated with 24 Kewl Tune and tuner pieces, so the starter is almost always present
• 10 hand traps give going-second interaction and layered protection
• Compact 19-card Main Deck with redundant synchro routes into 13 Synchro closers

Weaknesses

• No recorded boards, so the ceiling and median are not measured
• No sideboard in Master Duel, so no post-side adaptation
• Exact-name purity 36.4% means the engine leans on generic Tuners and hand traps

Critical choke points

• Kewl Tune Mix / Reco / Synchro (2 copies each, Semi-Limited) are the main search and recursion path; losing them to a hand trap slows the engine
• Over Tuning and Earthbound restrict non-Synchro Extra Deck summons, which can stall Fusion and Xyz follow-ups

Recommended changes

Evidence & confidence

• Verified: Legal under BanMasterDuel with main 40 and extra 15, zero violations; All 8 restricted cards at or under legal copy limits; Kewl Tune core present by name in 24 of 25 usage-core entries (Crossout Designator absent)
• Inferred: Starter, hand-trap and brick probabilities (hypergeometric); Ceiling read from card text (Loudness War, Remix, B2B); Interaction and recovery quality from card text
• Provisional: Meta Power (no dated sample); Matchup and format fit (no tournament data); Post-side score (no sideboard in Master Duel)
• Data gaps: No combos supplied, so floor, median and ceiling are text-only inference No tournament link, so archetype meta-share and per-pilot record are absent No win-rate telemetry for going-first, going-second, matchups or brick rates Evidence defect: usage_statistics.missing_core marks 12 cards as absent (Wind Pegasus, Loudness War, Malong, Remix, Crackle, Track Maker, B2B, Zalen, TY-PHON, Albion, Packbit) that appear in this deck's Extra Deck by name; the in_this_deck flag appears to check only the Main zone. Core coverage is taken from names, not the flag Meta Power is Provisional unless a dated metagame sample is supplied
