Kewl Tune Deck #772717 — Yu-Gi-Oh! OCG

Deck — Deck Power Evaluation

Final Contextual Deck Power: 51/100 (±6 · Confidence: Medium)

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

Legality

Main 41 / Extra 14 / Side 0 — status: Legal with warning.

Identity & game plan

• Win condition: Blue-Eyes Ultimate Dragon (4500 ATK, up to 3 attacks) or Blue-Eyes Chaos MAX Dragon (4000 ATK, double piercing), reached through Blue-Eyes White Dragon Fusion, Ultimate Fusion or Ritual lines; Blue-Eyes Spirit / Ultimate Spirit Dragon Synchro boards and Dragon Master Magia, all of which depend on Blue-Eyes White Dragon or a Tuner-plus-Blue-Eyes base
• Turn 1 (going first): Normal Summon a Level 1 Tuner (Sage with Eyes of Blue, Dominusteer Rosepamela, Kaibaman the Legend or Effect Veiler), search a second Tuner or Blue-Eyes White Dragon, and build a Synchro or Fusion board. Hand traps (Ash Blossom, Maxx C, Droll & Lock Bird) are held up for the opponent's first search or draw
• Turn 2 (going second): Use Ash Blossom, Droll & Lock Bird or Effect Veiler to break the opponent's first engine, then take a board through Synchro or Fusion with Blue-Eyes or Dominus negations (Dominus Purge, Songs of the Dominators) as backup
• Recovery: Recursion from the GY through Kaibaman, Maiden of White, Deep-Eyes White Dragon and Blue-Eyes Spirit / Ultimate Spirit Dragon effects, plus Bingo Machine, Wishes for Eyes of Blue and Primite Lordly Lode to refill the hand
• After siding: None. The list has no Side Deck (Side Deck size 0), so there is no post-side plan and the deck cannot adapt between games

Why it scores here

The deck reliably reaches a searcher on turn 1 (P(at least one of 20 searcher-text cards in a 5-card opening hand) is about 0.97), so it has a live first action in most games. Its engine is fragile, though. Each key starter (Sage, Blue-Eyes White Dragon) has only 3 copies, giving about 0.33 odds of one in a 5-card hand, and only 5 of the 55 cards are archetype core, so the deck is a Blue-Eyes/Dominus/Primite hybrid under a Kewl Tune label. Five hand traps and 17 removal or negation texts give it real interaction, and its closers (Blue-Eyes Ultimate Dragon, Chaos MAX) are strong once summoned. The score comes from consistency, closing power and interaction across the whole system, not from averaging card scores. Popularity did not earn points: the deck has 0 recorded boards and no tournament link, and the list has no side deck, which caps post-side adaptability.

Dimension scores

How the score was computed

Strategy profile: Pure Midrange weights; Combo and Toolbox are noted as secondary, not blended. Structural ≈ 58, Going First ≈ 59, Going Second ≈ 58, Meta = provisional, Tournament Reliability ≈ 47. Modifiers: banlist exposure (-2); no side deck (-3); engine conflict and archetype dilution (0). Final formula: 0.80*Structural + 0.20*TournamentReliability + ContextModifiers (Meta provisional, no dated metagame sample)

Probability & combo summary

• Opening a starter: P(≥1) ≈ 0.33 · 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

• Live first action on turn 1 in almost every opening hand (searcher density)
• Five hand traps and about 25 negation or removal texts give layered interaction
• Strong closers once summoned: Blue-Eyes Ultimate Dragon and Chaos MAX
• Good recursion from the GY through Kaibaman, Maiden and Deep-Eyes

Weaknesses

• Key 3-copy starters (Sage, Blue-Eyes White Dragon) are unreliable in opening hands (about 0.33)
• Archetype label mismatch: 54 of 55 copies are off the Kewl Tune name and 9 of 13 core cards are missing
• No side deck, so no post-side adaptation
• Three summon types and many conditional starters make it hard to pilot

Critical choke points

• Blue-Eyes White Dragon is the single base for most Blue-Eyes lines; losing it to a hand trap or removal shuts off the Ultimate Dragon and Spirit routes
• The Normal Summon-dependent Tuner starters need a free Main Phase, so a Normal Summon blocker or Nibiru-style reset removes the turn-1 plan

Recommended changes

Evidence & confidence

• Verified: Legality is Legal with warning: 41 Main, 14 Extra, 0 Side; the Main count is within the OCG range 40-60; Limited (1 copy): Bystial Magnamhut, Droll & Lock Bird, Maxx C; Semi-Limited (2 copies): Ash Blossom & Joyous Spring; Card text and stats for the Blue-Eyes Ultimate Dragon (4500 ATK) and Chaos MAX (4000 ATK); Archetype spread: Blue-Eyes 19, generic 15, Dominus 6, Primite 5, with Eyes of Blue 4, exact Kewl Tune 1
• Observed: Usage data: Ash Blossom, Maxx C and Droll are core in the archetype (about 70% inclusion); 9 of 13 core cards are not in this list
• Inferred: Opening-hand odds: searcher about 0.97, 3-copy starter about 0.33, hand trap on going second about 0.57 (hypergeometric); Strategy profile Midrange with Combo and Toolbox secondary, from the 12 Tuners, 20 searchers and 8 Synchro, 3 Fusion, 3 Link Extra Deck; Interaction and recursion strength from the text roles, with no recorded boards to confirm them
• Provisional: Meta Power is null: no dated metagame sample; D13 matchup and format fit: no tournament link and no archetype meta-share
• Data gaps: No combos supplied: combo floor, median and ceiling are text-only inference No tournament link: archetype meta-share and per-pilot match record are absent One passcode (23995346) could not be resolved to a card and is counted as Main No win-rate telemetry (going first or second, matchup, starter or brick rates) No guides for the archetype (guide data total 0) Meta Power is provisional unless a dated metagame sample is supplied
