Kewl Tune Deck #772393 — Yu-Gi-Oh! OCG

Deck — Deck Power Evaluation

Final Contextual Deck Power: 20/100 (±8 · Confidence: Low)

• Primary strategy: Midrange
• Secondary strategies: Toolbox, Stun
• Format: ocg

Legality

Main 56 / Extra 14 / Side 0 — status under the rules at evaluation time: Illegal. 2 violation(s).

Identity & game plan

• Win condition: Blue-Eyes beatdown through Blue-Eyes Ultimate Dragon, Neo Blue-Eyes Ultimate Dragon, Blue-Eyes Ultimate Spirit Dragon and Dragon Master Magia, after setting up Blue-Eyes White Dragon and Blue-Eyes Spirit Dragon; Synchro and Xyz board-breaking (Indigo-Eyes Silver Dragon negation and Ekhajar banish) once the board is established
• Turn 1 (going first): Normal Summon Sage or Maiden of White, search or summon Blue-Eyes tuners, and build toward Blue-Eyes Spirit Dragon while holding Infinite Impermanence and Effect Veiler for the opponent's first interaction
• Turn 2 (going second): Use hand traps (Ash Blossom, Ghost Ogre, Droll and Lock Bird, Maxx C, Effect Veiler) to strip the opponent's starter, then rebuild the Blue-Eyes board with Mulcharmy draws
• Recovery: Mulcharmy Fuwalos and Purulia draw cards when the hand is larger than the opponent's, Maiden of White and Ghost Ogre recur from the GY, and Blue-Eyes White Dragon can be re-summoned via Kaibaman and Sage
• After siding: No Side Deck is registered, so no post-side plan exists in the evidence

Why it scores here

The deck opens a Blue-Eyes starter reliably enough to be playable: three copies each of Sage with Eyes of Blue, Maiden of White, Mulcharmy Fuwalos and Blue-Eyes White Dragon give roughly a 25% chance of at least one in a 5-card opening hand (hypergeometric, Inferred). Its resilience comes from a dense hand-trap suite (10 hand traps and 16 tuners) that can answer a starter on the opponent's turn. Its interaction on the end board (Solemn Judgment, Infinite Impermanence, Dragon's Mind, Crossout Designator, Anti-Spell Fragrance) and its closing threats (Neo Blue-Eyes, Blue-Eyes Ultimate Spirit Dragon, Dragon Master Magia) carry most of the structural score. The list is not a coherent Kewl Tune deck: only one Kewl Tune card is run and the archetype core is largely absent, so the Kewl Tune name does not earn points, and the Ritual monsters have no Chaos Form to summon them. The deck is Illegal because Baronne de Fleur is Forbidden in OCG, so the score is capped at 20 and framed as a theoretical, structural-only read. No card scores were averaged into this result.

Dimension scores

How the score was computed

Strategy profile: Midrange weights used; Toolbox secondary noted only as context. Structural ≈ 51, Going First ≈ 46, Going Second ≈ 50, Meta = provisional, Tournament Reliability ≈ 35. Modifiers: banlist_exposure (-8); engine_conflict (-4). Final formula: No reliable metagame: 0.80*Structural(51) + 0.20*TournamentReliability(35) = 47.8; context modifiers -12 gives 35.8; Illegal legality cap applied, final 20 (theoretical, structural-only)

Probability & combo summary

• Opening a starter: P(≥1) ≈ 0.25 · 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

• Dense hand-trap suite (10 hand traps) for going second
• Layered end-board interaction (Solemn Judgment, Infinite Impermanence, Dragon's Mind, Crossout Designator)
• High-ceiling closers: Neo Blue-Eyes, Blue-Eyes Ultimate Spirit Dragon, Dragon Master Magia

Weaknesses

• Illegal under OCG rules (Baronne de Fleur Forbidden)
• No Side Deck
• Kewl Tune identity not actually built; archetype core absent
• Ritual monsters without Chaos Form

Critical choke points

• Blue-Eyes White Dragon (3 copies) as the sole route to most closers
• Chaos Form absent for the Ritual Blue-Eyes Chaos MAX and Magician of Black Chaos MAX

Recommended changes

Evidence & confidence

• Verified: Illegal status: Baronne de Fleur Forbidden with 1 copy run; Main 56, Extra 14, Side 0 counts; Blue-Eyes Ultimate Spirit Dragon, Neo Blue-Eyes and Dragon Master Magia stats
• Inferred: Starter opening probabilities (~0.25 per 3-copy card); Interaction density read from card text; Brick and engine-conflict estimates
• Provisional: Matchup and format fit (no dated meta); Going-first and going-second splits
• Data gaps: No combos supplied: floor, median and ceiling are text-only inference No tournament link: archetype meta-share and per-pilot record absent No Side Deck supplied 1 passcode (23995346) in CardIDList could not be resolved and is counted as main No win-rate telemetry for this deck Meta Power is Provisional unless a dated metagame sample is supplied
