Kewl Tune Deck #762942 — Yu-Gi-Oh! Master Duel

Deck — Deck Power Evaluation

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

• Primary strategy: Combo
• Secondary strategies: Stun, Mechanic: Synchro/Tuner
• Format: master-duel

Legality

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

Identity & game plan

• Win condition: Synchro boss summons (Zalen, Kewl Tune B2B, Kewl Tune Loudness War, Albion, Visas) reached through a Tuner-chain starter; Hand-trap and negation control that stops the opponent's first line, then summons through the resulting board
• Turn 1 (going first): Open a Tuner (Kewl Tune Mix, Reco, Cue, Rotary or Clip) or a search effect, reach a Synchro starter, and keep Ash Blossom, Infinite Impermanence or Effect Veiler up for the opponent's first response
• Turn 2 (going second): Use the 6-card hand's hand traps (Ash Blossom, Infinite Impermanence, Effect Veiler, Droll & Lock Bird, Ghost Ogre, Ghost Belle, Maxx C) to answer the opponent's opening, then Synchro through their board
• Recovery: Recur Tuners from the GY (Kewl Tune Mix and Reco effects, Ghost Belle) and use the Kewl Tune Synchro and Duelist Genesis searches to rebuild the Synchro line
• After siding: Not applicable: Master Duel single-game format with side_count 0 and no sideboard in this list

Why it scores here

The deck reliably opens a functional first line: 20 Tuner monsters give about a 98% chance of at least one Tuner in a 5-card opening hand, and the 15 search-text cards give about 92% for a searcher. Its 15 hand-trap and negation cards keep it functional when the opponent interrupts, and the chance of holding at least one hand trap when going second is about 95%. Conversion into pressure is driven by 12 distinct Extra Deck Synchro and Fusion bosses, which score on the system rather than on any individual card. Popularity and the guide's claim of meta strength did not earn points, and no card scores were averaged. The score is held back by the absence of recorded combos, the 36% exact-archetype purity, the fragile single-copy Limited starters, and the complex Tuner timing that a pilot must manage.

Dimension scores

How the score was computed

Strategy profile: Combo. Structural ≈ 72, Going First ≈ 74, Going Second ≈ 77, Meta = provisional, Tournament Reliability ≈ 66. Modifiers: banlist exposure (-1); engine redundancy (2); off-archetype splash (-2). Final formula: 0.80*Structural + 0.20*TournamentReliability + ContextModifiers (Meta provisional; D13 dropped from Structural and weights renormalized over 97)

Probability & combo summary

• Opening a starter: P(≥1) ≈ 0.92 · key two-card combo ≈ — · full-brick estimate ≈ 0.01 (all Inferred)
• Combo output: best PowerIndex —, median —, board-per-starter —
• Turn order: 0 going-first lines vs 0 going-second lines

Strengths

• 15 hand-trap and negation cards give strong going-second interaction (about 95% at least one hand trap in 6 cards)
• 20 Tuner monsters make a Synchro starter very likely in the opening hand (about 98%)
• 12 distinct Extra Deck Synchro and Fusion bosses offer varied closing routes
• All restricted cards are at or below their legal copy limits

Weaknesses

• No recorded combo boards, so ceiling and median are inferred and not observed
• Exact-name archetype purity is 36.4%; off-archetype cards dilute the engine
• Starter access depends on single-copy Limited cards (Kewl Tune Cue, Rotary)
• No side deck in this list, so post-side adaptability cannot be shown
• High Tuner timing complexity raises the error rate for the pilot

Critical choke points

• Kewl Tune Cue and Kewl Tune Rotary are single-copy Limited starters; losing them reduces the opening Tuner options
• Synchro conversion depends on having a Tuner in hand or GY, which the hand-trap and recursion cards compete for

Recommended changes

Evidence & confidence

• Verified: Legal status: 40 Main, 15 Extra, 0 Side within Master Duel size rules [40,60]/[0,15]/[0,15]; All restricted cards are at or below legal copies (Limited 1, Semi-Limited 2); Hypergeometric draw odds for 1, 2 and 3 copies in 5-card and 6-card hands; Composition counts: 20 Tuner monsters, 15 hand-trap-tagged cards, 15 searcher-text cards, 14 Synchro and 1 Fusion in Extra
• Observed: Usage statistics show the archetype-standard core; Extra Deck entries are marked in_this_deck false by the export, which is a main-deck-only match (see data_gaps)
• Inferred: Opening-hand consistency and Tuner-based starter access; Interaction density and resilience from card text; Going-second hand-trap coverage and board-breaking read; Closing power from listed Extra Deck ATK and effects
• Provisional: Meta Power is null: no dated metagame sample; Matchup and format fit (D13) is provisional and excluded from Structural; Side adaptability (D12) is a neutral placeholder: no side deck in this format
• Data gaps: No combos supplied: combo floor, median and ceiling are text-only inference No tournament link: archetype meta-share and pilot match record are absent No win-rate telemetry exists: going-first, going-second, matchup and brick rates are Inferred or Unknown Usage statistics appear to match only Main Deck entries: Extra Deck cards such as Kewl Tune Remix, Track Maker, Crackle and Loudness War are present in the deck but reported as in_this_deck false, so the 52% core-present figure understates coverage; by name, 22 of 25 core cards are present Side deck is empty; the format has no post-side plan in this export Meta Power is Provisional unless a dated metagame sample is supplied
