Kewl Tune Deck #765887 — Yu-Gi-Oh! Master Duel

Deck — Deck Power Evaluation

Final Contextual Deck Power: 68/100 (±6 · Confidence: Medium)

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

Legality

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

Identity & game plan

• Win condition: Tuner-chain Synchro Summons (Kewl Tune Mix / Reco / Clip / Rotary / Cue into Kewl Tune Synchro, Track Maker, Remix, RS) that land Extra Deck boards such as Loudness War, B2B, Visas Amritara, Zalen, Packbit and Malong; Hand-trap-supported going-second boards that stop the opponent's Synchro or Extra Deck line and then convert with Tuner recursion
• Turn 1 (going first): Open Tuner and searcher pieces, Normal Summon a Tuner, search via Kewl Tune Mix/Reco/Rotary, then Synchro Summon into an Extra Deck closer while holding a hand trap for the opponent's first interaction (Inferred)
• Turn 2 (going second): Use the six-card hand's hand traps (Ash, Ghost Ogre, Ghost Belle, Effect Veiler, Impermanence, Maxx C, Droll) to break the opponent's first board, then rebuild through Tuner recursion and Synchro Summon (Inferred)
• Recovery: Recover from disruption through GY-based searchers (Kewl Tune Mix, Reco, Rotary, Cue, Clip) and Kewl Tune Synchro, which can add a Kewl Tune card and Synchro Summon again (Inferred)
• After siding: Not applicable: no Side Deck in Master Duel format (Side Deck size 0)

Why it scores here

The deck opens a Synchro plan very reliably: 22 of 40 Main Deck cards are Tuners, so P(at least one Tuner in a 5-card opening hand) is about 0.99 (Inferred), and the archetype core group is essentially always present in hand. Recovery is strong because several Kewl Tune Tuners and Kewl Tune Synchro can search or recur from the GY, and the 14 Extra Deck Synchros offer multiple closers and endboard protection (Loudness War, RS, Packbit, Zalen). Interaction density is high, with about 18 hand-trap-tagged Main Deck cards and 13 negation-text cards, which lifts going-second board breaking and endboard quality. The score comes from consistency, redundancy, and interaction on the system, not from popularity: the Vietnamese guide describing this as a top meta deck is unverified and did not earn points, and card scores were not averaged. Scoring is held back by the absence of recorded combos, win-rate telemetry, and a side deck, plus the risk that hand-trap-heavy openers are dead when going first.

Dimension scores

How the score was computed

Strategy profile: Combo. Structural ≈ 71, Going First ≈ 66, Going Second ≈ 74, Meta = provisional, Tournament Reliability ≈ 66. Modifiers: banlist exposure (-2); engine compactness (0). Final formula: 0.80*Structural + 0.20*TournamentReliability (Meta provisional) + ContextModifiers

Probability & combo summary

• Opening a starter: P(≥1) ≈ 0.99 · key two-card combo ≈ — · full-brick estimate ≈ 0 (all Inferred)
• Combo output: best PowerIndex —, median —, board-per-starter —
• Turn order: 0 going-first lines vs 0 going-second lines

Strengths

• 22 Tuners in the Main Deck make Synchro access near-certain in the opening hand
• Strong recovery through Kewl Tune searchers and Synchro recursion from the GY
• Dense interaction: 18 hand-trap-tagged cards and 13 negation-text cards
• Extra Deck of 14 Synchros offers several closers and endboard protection

Weaknesses

• No Side Deck, so there is no post-side plan (D12 low by construction)
• Hand-trap-heavy openers may be dead when going first without opponent action
• Combo ceiling and median cannot be measured: no recorded boards
• High timing and decision load (D14 low)

Critical choke points

• Kewl Tune Mix / Reco (Semi-Limited, 2 copies) are the main engine searchers; losing them to a banlist change would reduce recovery
• Going-first hands that hold only hand traps with no Tuner-Synchro line

Recommended changes

Evidence & confidence

• Verified: Legal: 40 Main, 15 Extra, copy limits respected for all restricted cards (BanMasterDuel); Composition: 22 Tuners, 14 Synchros, 1 Xyz, 36.4% exact-name purity
• Inferred: P(at least one Tuner in opening 5) ≈ 0.99; Hand-trap coverage on going second ≈ 0.98; Going-first and going-second plans and combo lines from card text
• Provisional: Meta Power (null): no dated metagame sample; D13 matchup/format fit (score 60)
• Data gaps: no combos supplied: combo floor/median/ceiling is text-only inference no tournament link: archetype meta-share and per-pilot match record absent no win-rate telemetry (going-first/second, matchup, brick/starter rates) in YGOVN Meta Power provisional: no dated metagame sample usage statistics in this deck flags conflict with the cards list for several Extra Deck cards (Loudness War, Malong, Ignister, Remix, Crackle, Track Maker, B2B, Zalen, Packbit, TY-PHON); the cards list was used as the source of truth no Side Deck in Master Duel, so best-of-3 post-side evaluation is not applicable
