Kewl Tune Deck #769988 — Yu-Gi-Oh! OCG

Deck — Deck Power Evaluation

Final Contextual Deck Power: 25/100 (±10 · Confidence: Low)

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

Legality

Main 43 / Extra 14 / Side 0 — status under the rules at evaluation time: Illegal. 3 violation(s).

Identity & game plan

• Win condition: Blue-Eyes large beaters (Blue-Eyes Ultimate Dragon 4500 ATK, Blue-Eyes Chaos MAX 4000 ATK via Ritual, Blue-Eyes Spirit and Stardust Sifr Synchros) backed by Blue-Eyes White Dragon recursion and Fusion pressure; Dragon Master Magia and Blue-Eyes Tyrant Dragon Fusion pressure; Ancient Fairy Life Dragon and Ekhajar as card-advantage and board-breaking Synchros
• Turn 1 (going first): Search with Sage with Eyes of Blue, Maiden of White, Wishes for Eyes of Blue, Dominusteer Rosepamela or Deep-Eyes; extend into a Tuner Synchro or Link Summon (Spirit with Eyes of Blue) and protect with Ash Blossom, Effect Veiler or Infinite Impermanence
• Turn 2 (going second): Hold Ash Blossom, Effect Veiler, Droll and Lock Bird, Maxx C or Ghost Ogre to answer the opponent's first summon or search, then rebuild a Blue-Eyes board through Majesty of the White Dragons or Ultimate Fusion
• Recovery: Blue-Eyes White Dragon recursion from the GY (Maiden of White, Deep-Eyes, Kaibaman the Legend, Roar of the Blue-Eyed Dragons) and Sage/Wishes search to rebuild Synchro material
• After siding: No sideboard is registered, so there is no post-side plan; any best-of-3 use would be unchanged

Why it scores here

This list is scored as a whole system and not as an average of its cards. It reliably reaches a Blue-Eyes starter through its 16 searcher-text cards (about 92% chance of at least one in a 5-card opening hand, Inferred), but the core Blue-Eyes White Dragon appears in only about 32% of opening hands, so the engine is accessible yet not dependable on turn 1. Interaction is the strongest part of the build: 9 hand traps and about 10 negation-text cards give layered answers that are especially good going second (about 78% chance of at least one hand trap in a 6-card hand, Inferred). Closing power is high through Blue-Eyes Ultimate Dragon, Chaos MAX and Stardust Sifr. The score is pulled down by the Illegal status (a Forbidden card is run), the empty Side Deck, the very low archetype purity (only 1 exact 'Kewl Tune' card of 57, with 'Kewl Tune' core cards almost all missing), and the absence of any recorded boards. Popularity and archetype label do not add points, and the score is capped because the list is not legal.

Dimension scores

How the score was computed

Strategy profile: Midrange 100%; Toolbox not blended into weights. Structural ≈ 53.3, Going First ≈ 52, Going Second ≈ 60, Meta = provisional, Tournament Reliability ≈ 45. Modifiers: Banlist exposure (Forbidden card run) (-8); Archetype incoherence (-3); No side deck (-2); Legality cap (-2). Final formula: Illegal list: normal 0.80*Structural + 0.20*TournamentReliability + modifiers = about 40 (theoretical), capped to 25 because the deck runs a Forbidden card and has an empty Side Deck; Meta Power provisional/null

Probability & combo summary

• Opening a starter: P(≥1) ≈ 0.32 · 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

• Layered hand-trap and negation suite (Ash Blossom, Effect Veiler, Infinite Impermanence, Ghost Ogre, Droll and Lock Bird, Maxx C)
• Dense searcher text (16 cards) gives high probability of a live opening hand
• High-ceiling Extra Deck pressure: Blue-Eyes Ultimate Dragon, Blue-Eyes Chaos MAX, Stardust Sifr, Dragon Master Magia

Weaknesses

• Deck is illegal: Baronne de Fleur is Forbidden and is run
• Exact archetype purity is 1.8%; the Kewl Tune label does not reflect the actual engine
• Empty Side Deck
• No recorded combo boards, so the floor and median are unknown

Critical choke points

• Blue-Eyes White Dragon is the single main engine piece and appears in only about 32% of opening hands
• Synchro and Fusion lines depend on Blue-Eyes material being present on the field
• Tuner-dependent Synchro summons: a single Tuner shortage stalls the Extra Deck

Recommended changes

Evidence & confidence

• Verified: Legality: Baronne de Fleur Forbidden, 1 copy run, list status Illegal; Main 43, Extra 14, Side 0; size rules satisfied; Usage stats: Kewl Tune core present 7 of 16 (43.8%)
• Inferred: Opening-hand consistency from hypergeometric estimates (P of searcher 0.92, P of Blue-Eyes White Dragon 0.32); Interaction density and negate coverage from card text; Going-second hand-trap coverage 0.78
• Provisional: Meta Power (null, no dated metagame sample); Matchup and format fit (D13)
• Data gaps: no combos supplied: combo floor, median and ceiling are text-only inference no tournament link: archetype meta-share and per-pilot record absent 1 passcode in the main deck could not be resolved to a card no win-rate telemetry (going-first, going-second, matchup, brick and starter rates) Meta Power is Provisional unless a dated metagame sample is supplied Deck title is null and no guides are attached
