Deck — Deck Power Evaluation

Final Contextual Deck Power: 53/100 (±8 · Confidence: Medium)

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

Legality

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

Identity & game plan

• Win condition: Synchro pressure from Kewl Tune Synchro boards (B2B, Loudness War, Track Maker, Remix, Zalen lines); Inferred from card text; Fydraulis Harmonia and Zalen negate-and-summon interaction converting into Synchro boards (Inferred)
• Turn 1 (going first): Open a Tuner plus a non-Tuner starter using Kewl Tune Mix, Reco, Synchro or JJ, Normal Summon a Tuner, then Synchro into a Kewl Tune board while holding hand traps for the opponent's first activation (Inferred)
• Turn 2 (going second): Keep one or two hand traps (Ash, Ghost Belle, Ghost Ogre, Effect Veiler, Maxx C) to answer the opponent's first summon or effect, then rebuild a Tuner-based Synchro line (Inferred)
• Recovery: Recursion from GY: Kewl Tune Mix and Reco search Kewl Tune cards from GY, and Tuners return through Track Maker and B2B (Inferred)
• After siding: No side deck is registered (side 0); no post-side plan is available

Why it scores here

The deck reliably opens a Tuner-based starter: the archetype-core proxy gives about 0.997 for at least one core card in a 5-card opening hand, and the 15 searcher-text copies give about 0.92 for at least one in 5 cards (Inferred). It converts that starter into Synchro pressure through a 14-card Synchro Extra Deck with redundant Tuner routes. Its survival rests on 13 hand traps, about 0.92 odds of at least one in a 6-card going-second hand (Inferred). The score is held back by Tuner overlap between hand traps and Synchro material, a 36 percent exact-name purity with off-archetype Mulcharmy, Earthbound and Branded/Ecclesia cards, no side deck, and no combo or tournament data. Popularity and the guides' claim of meta strength earned no points, and no card scores were averaged.

Dimension scores

How the score was computed

Strategy profile: Combo. Structural ≈ 61.5, Going First ≈ 55, Going Second ≈ 60, Meta = provisional, Tournament Reliability ≈ 55. Modifiers: engine conflicts (-3); no side deck (-2); missing Fallen of Albaz enabler (-2). Final formula: No dated meta sample, so Final = 0.80*Structural(61.5) + 0.20*TournamentReliability(55) + ContextModifiers(-7) = 53.2, rounded to 53

Probability & combo summary

• Opening a starter: P(≥1) ≈ 1 · 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

• 13 hand traps give about 0.92 odds of one in a 6-card going-second hand
• Redundant Tuner routes with 14 Synchro monsters and 15 searcher-text copies
• Extra Deck is fully used with no empty slots
• Kewl Tune core cards are present at near-certain opening-hand odds

Weaknesses

• Hand-trap Tuners compete with Synchro starters and materials
• Exact-name purity is 36.4 percent, with off-archetype Mulcharmy, Earthbound and Ghost copies
• Albion and Ecclesia lack a visible Fallen of Albaz enabler
• No side deck is registered
• No combo, tournament or win-rate evidence

Critical choke points

• Two-copy Mix, Reco, Synchro and JJ: about 0.24 odds for at least one in a 5-card hand

Recommended changes

Evidence & confidence

• Verified: Legal in Master Duel with 40 main, 15 extra and 0 side; All Limited and Semi-Limited copy counts are within legal limits; Composition and role-tag counts from the resolved list; Usage-stat core status for the 25 core cards
• Inferred: Opening-hand and going-second consistency estimates; Engine and interaction read from card text; Structural and final score components
• Provisional: Meta Power and format fit (D13), pending a dated meta sample
• Data gaps: No combos supplied, so floor, median and ceiling are text-only inference No tournament link, so archetype meta-share and pilot match record are absent No win-rate telemetry (going-first, going-second, matchup, brick, starter or OTK rates) Meta Power is provisional without a dated metagame sample usage_statistics in_this_deck flags contradict the cards list for Kewl Tune Remix, Track Maker, Crackle, Loudness War, Malong and Pegasus; the cards list was used Fallen of Albaz is not in the Main or Extra list, so Albion and Ecclesia routes are unverified
