Kewl Tune Deck #747028 — Yu-Gi-Oh! Master Duel

Deck — Deck Power Evaluation

Final Contextual Deck Power: 40/100 (±10 · Confidence: Medium)

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

Legality

Main 40 / Extra 15 / Side 0 — status under the rules at evaluation time: Illegal. 4 violation(s).

Identity & game plan

• Win condition: Synchro Summon Kewl Tune Tuner-based boards (Kewl Tune Track Maker, Kewl Tune RS, Kewl Tune Remix, Kewl Tune Crackle) and convert the board into attacks or removal; Negate and disrupt the opponent's key effects with hand traps (Ash Blossom, Infinite Impermanence, Effect Veiler, Ghost Belle) and then extend through Extra Deck Synchro Summons
• Turn 1 (going first): Open with a Tuner starter (Kewl Tune Cue, Mix, Reco or Rotary), use a searcher such as Duelist Genesis or JJ "Kewl Tune" to find the next Kewl Tune piece, and Synchro Summon into a Synchro monster from the Extra Deck
• Turn 2 (going second): Hold two or more hand traps (Ash Blossom, Effect Veiler, Infinite Impermanence, Ghost Belle) to negate the opponent's first starter, then rebuild a Tuner board from the Deck and GY
• Recovery: Recycle Tuners from the Graveyard through Kewl Tune Synchro and Kewl Tune Mix searches, and reuse the Extra Deck Synchro monsters that Kewl Tune Loudness War and Kewl Tune Remix can revive or retrieve
• After siding: No side deck is listed (Master Duel format), so there is no post-side plan; the deck must adjust by the choice of Extra Deck monsters and hand traps

Why it scores here

The deck is scored as a connected Tuner system, not as an average of its cards. Its Kewl Tune core (18 copies, about 96% chance of at least one in an opening five) gives it reliable access to a starter, and 13 hand traps give it a strong going-second interaction plan. Its ceiling and median are both limited by the evidence: the only recorded line scores 9, and no recorded board shows a second independent route, so conversion is rated low and marked Inferred. The score is held down by the list itself, which runs three Limited cards at two copies each and one Forbidden card, so the deck cannot be played as written. Popularity in the archetype and the guide claim that this is the strongest deck of its meta do not earn points, because no dated tournament sample supports them.

Dimension scores

How the score was computed

Strategy profile: Combo. Structural ≈ 52, Going First ≈ 55, Going Second ≈ 60, Meta = provisional, Tournament Reliability ≈ 50. Modifiers: banlist exposure (-12). Final formula: 0.80*Structural(52) + 0.20*TournamentReliability(50) = 51.6, then Illegal-list banlist exposure modifier -12 = 40 (Meta provisional)

Probability & combo summary

• Opening a starter: P(≥1) ≈ 0.96 · key two-card combo ≈ — · full-brick estimate ≈ 0.04 (all Inferred)
• Combo output: best PowerIndex 9, median 9, board-per-starter 0
• Turn order: 0 going-first lines vs 0 going-second lines

Strengths

• Core Tuner engine is easy to open (about 96% chance of a core card in five cards)
• Thirteen hand traps give strong answers to the opponent's first play when going second
• Extra Deck uses all 15 slots with several Kewl Tune Synchro options

Weaknesses

• Illegal as built: three Limited cards over the copy limit and one Forbidden card
• Recorded lines are almost absent (one line, power index 9), so the conversion ceiling is unproven
• Heavy Tuner density (32 of 40 main cards) leaves hands prone to redundancy

Critical choke points

• Every Synchro line depends on at least one Tuner in hand or GY; a board with no Tuner stops the engine
• The Limited Kewl Tune Cue, Mix and Reco copies must drop to one each, which weakens the starter count

Recommended changes

Evidence & confidence

• Verified: Main 40 and Extra 15 counts meet Master Duel size limits; Three Limited cards over the copy limit and one Forbidden card in the list; Archetype core inclusion figures from usage statistics
• Observed: Single recorded line with power index 9 and no board presence; Resource signature shows one card in hand at end and no banished or graveyard cards in the recorded line
• Inferred: Opening-hand starter probability (0.96) and hand-trap probability (0.92); Brick and redundancy estimates from Tuner density; Interaction quality from card text
• Provisional: Meta power and matchup fit (no dated meta sample); Post-side plan (no side deck in format)
• Data gaps: No tournament link, so archetype meta-share and per-pilot match record are absent No win-rate telemetry exists for going-first, going-second, matchup, brick or OTK rates Only one recorded combo line exists, so median and ceiling are thin Meta Power is provisional unless a dated metagame sample is supplied
