Kewl Tune Deck #765360 — Yu-Gi-Oh! Master Duel

Deck — Deck Power Evaluation

Final Contextual Deck Power: 62/100 (±8 · Confidence: Medium)

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

Legality

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

Identity & game plan

• Win condition: Tuner-based Synchro Summons (Kewl Tune Synchro/Mix/Reco searches into Kewl Tune Track Maker, Remix, Loudness War, B2B or Crackle) that convert a board into 2,800-3,300 ATK bosses (Inferred from card text); Hand-trap and negation interaction (Ash Blossom, Ghost Ogre, Ghost Belle, Effect Veiler, Maxx C) that strips the opponent's board before the Synchro line lands (Inferred)
• Turn 1 (going first): Turn 1 search via Duelist Genesis / Kewl Tune Synchro / Kewl Tune Mix, then a Tuner-plus-Tuner Synchro Summon into a boss while holding hand traps for the response window (Inferred)
• Turn 2 (going second): Hold 2 to 3 hand traps from the 6-card hand and negate or destroy the opponent's first board-building effect, then Synchro through the open board (Inferred)
• Recovery: Recover Tuners from the GY through Ghost Belle, Kewl Tune Reco/Mix GY effects and Synchro GY effects, then rebuild a Synchro line from the Deck searchers (Inferred)
• After siding: Not applicable: Master Duel uses no Side Deck in this list (side_count 0), so adaptation is limited to in-game choices

Why it scores here

The deck reliably opens its engine: 17 searcher-text cards give about a 95% chance of at least one in a 5-card opening hand, and the three Kewl Tune Synchro/Mix/JJ searchers plus Duelist Genesis cover most openings (Inferred from the hypergeometric estimates). Its interaction suite is the strongest part of the score: 10 hand-trap-tagged cards and 7 negation-text cards give roughly an 85% chance of at least one hand trap in a 6-card going-second hand, and this is what drives the End-Board and Going-Second scores. Conversion is credible but unmeasured, because no recorded boards exist, so the ceiling and median scores rest on card-text reads and are labeled Inferred. The main weakness is structural: 19 of 40 main-deck cards are Tuners and only 7 are non-Tuner monsters, while several Extra Deck splash cards (Albion, Ecclesia) depend on Fallen of Albaz, which the list does not run. The score is built from consistency, interaction and resilience on the whole system; it does not come from averaging card scores, and the archetype's popularity earned no points.

Dimension scores

How the score was computed

Strategy profile: Midrange. Structural ≈ 67, Going First ≈ 74, Going Second ≈ 67, Meta = provisional, Tournament Reliability ≈ 64. Modifiers: non-Tuner density choke point (-3); off-plan Extra Deck splash (-2). Final formula: 0.80*Structural + 0.20*TournamentReliability + ContextModifiers (Meta provisional/null): 0.80*67.4 + 0.20*64 = 66.7; modifiers -5 = 61.7, rounded to 62

Probability & combo summary

• Opening a starter: P(≥1) ≈ 0.95 · key two-card combo ≈ — · full-brick estimate ≈ 0.05 (all Inferred)
• Combo output: best PowerIndex —, median —, board-per-starter —
• Turn order: 0 going-first lines vs 0 going-second lines

Strengths

• Searcher density (17 searcher-text cards) gives a near-certain starter
• Layered hand-trap and negation suite (10 hand traps, 7 negation texts) covers both turns
• Synchro bosses at 2,800-3,300 ATK give real closing power
• Recursion via Ghost Belle and Kewl Tune GY effects supports grind

Weaknesses

• Tuner-heavy Main (19 Tuners vs 7 non-Tuner monsters) starves Synchro lines that need non-Tuner materials
• Albion and Ecclesia are dead without Fallen of Albaz; Fallen & The Virtuous likewise needs those enablers
• No Side Deck, so no post-side adaptation
• Low exact-archetype purity (36.4%) signals an ecosystem build with many generic slots

Critical choke points

• Tuner density: a hand or board with only Tuners and no non-Tuner can stall Synchro lines that need one
• Hand-trap timing: most interaction is one-per-turn, and a single opponent Tuner-removal line can break the chain

Recommended changes

Evidence & confidence

• Verified: Main Deck 40 cards and Extra Deck 15 cards, legal with no violations (Master Duel size rules); Copy counts and banlist statuses match the restricted_cards list; Hypergeometric probabilities recompute correctly (0.3376, 0.2372, 0.3943, 0.9489, 0.8453); Extra Deck composition: 13 Synchro, 1 Fusion, 1 Xyz
• Inferred: Starter access and brick risk from searcher and Tuner density; Interaction quality from hand-trap and negation card text; Ceiling and median from card-text Synchro chains, since no combos were supplied; Going-first and going-second estimates from the component dimensions
• Provisional: Meta power (null) and matchup fit (D13); Side adaptability (D12), since there is no Side Deck and no post-side data
• Data gaps: No combos supplied: combo floor, median and ceiling are text-only inference No tournament link: archetype meta-share and match record are absent No win-rate telemetry exists in YGOVN; all performance signals are Inferred Meta Power is Provisional unless a dated metagame sample is supplied Usage-statistics mismatch: in_this_deck is false for Kewl Tune Remix, Track Maker, Loudness War, Crackle, Malong, Wind Pegasus, Zalen, B2B, Packbit, Albion, TY-PHON, and Ecclesia, although the cards list shows them as present in the Extra Deck. The core_present_pct of 52% is therefore unreliable; the Extra Deck was not matched in the usage calculation probabilities.archetype_core_group uses 24 copies while archetype_purity counts 20 exact-name copies; the group definition is unclear and was not used for scoring Guide snippets are Vietnamese and truncated; no section titles were available
