Legality

Main 55 / Extra 15 / Side 0 — status under the rules at evaluation time: Illegal. 5 violation(s).

Identity & game plan

  • Win condition: Tuner-chain Synchro Summons into 2800-3500 ATK boss monsters (Zalen, Chaos Angel, Kewl Tune B2B, Super Starslayer TY-PHON), backed by Kewl Tune Mix/Cue/Reco/Synchro searches; Kewl Tune Loudness War (3000 DEF) and Kewl Tune RS as Tuner-protection and negation boards that stall the opponent while the Synchro line continues
  • Turn 1 (going first): Open with a Kewl Tune searcher (Mix/Reco/Cue/JJ) into a Tuner-based Normal Summon or Special Summon, then reach a Synchro Summon using a Kewl Tune Tuner plus a non-Tuner; hold Ash/Infinite Impermanence for the opponent's first activation
  • Turn 2 (going second): Use Ash Blossom, Effect Veiler, Ghost Ogre, Droll & Lock Bird and Nibiru to answer the opponent's opening search or board, then rebuild with Kewl Tune Synchro or Duelist Genesis
  • Recovery: Recurrence through Kewl Tune Playlist, Kewl Tune Reco/Mix GY effects, Starjunk and Jet Synchron GY effects, and Triple Tactics Thrust to re-find Synchro starters after a hand-trap-heavy turn
  • After siding: Not evaluable: the deck has no side deck, so no post-side plan exists in the export

Why it scores here

The list is Illegal under OCG rules: three Ash Blossom copies exceed the Semi-Limited cap of 2, and three copies each of Kewl Tune Cue, Synchro and Reco exceed Limited caps of 1, and the deck has no side deck. The score therefore is not a normal Final Contextual score and is capped low, reported as theoretical/structural only. Structurally the deck's 55-card main has 38 Tuner-type cards and only about 7 non-Tuner monsters, which gives it real Synchro access through Kewl Tune but a high brick risk when hands are Tuner-heavy. Interaction density is strong: 19 hand-trap-tagged cards, 18 negation-text cards and a 93% going-second hand-trap hit rate make the deck difficult to answer with a single piece. Ceiling is credible from the Extra Deck (Zalen, Chaos Angel, Kewl Tune B2B) but no recorded boards exist to confirm a median. The score was built from the system (consistency, interaction, Extra Deck coverage) and was not averaged from card scores; popularity (Kewl Tune core present in 14 copies) earned no points on its own.

Dimension scores

# Dimension Score Evidence
D1 Engine Accessibility & Consistency 60 P(>=1 Kewl Tune Tuner or searcher in 5-card opening) is high given 14 archetype-core copies (P≈0.78 for >=1 core card); three-copy starters only ~0.25 each (Inferred)
D2 Opening-Hand Quality & Brick Management 35 25 Tuner monsters and 13 Synchro Tuners against only about 7 non-Tuner main-deck monsters and 23 level-0 cards; hand-trap-heavy hands frequently brick (Inferred)
D3 Combo Conversion & Ceiling 60 Extra Deck ceilings of 2800–3500 ATK (Zalen, Chaos Angel, Kewl Tune B2B) are reachable from two-Tuner setups; no recorded boards exist to confirm (Inferred from text)
D4 Combo Floor & Median Output 40 No combos_evidence and no parseable boards; median output cannot be measured and is estimated low-mid (Provisional)
D5 Interruption Resilience & Route Redundancy 55 Two-plus Tuner-protection Synchro routes plus Playlist and Reco recursion give some redundancy after a single negation (Inferred)
D6 Resource Economy, Recovery & Grind 50 Searchers (18 text hits) and GY recursion (Reco, Mix, Playlist, Jet Synchron) offset card spend, though the 55-card main is tight on resources (Inferred)
D7 End-Board & Interaction Quality 70 Ash Blossom x3 (over limit), Infinite Impermanence, Evenly Matched, Ghost Ogre and Effect Veiler layer negation across turns; 19 hand-trap-tagged cards (Verified tags, Inferred strength)
D8 Going-Second & Board-Breaking Power 60 Going-second hand-trap coverage: P(>=1 hand trap in 6-card hand) ≈ 0.93; Droll and Nibiru add board breaking (Inferred)
D9 Offensive Pressure & Closing Power 60 End-board ATK 2800–3500 from Extra Deck bosses; Loudness War and RS add durability but no direct closing damage (Inferred)
D10 Main Deck Efficiency & Flexibility 40 55-card main with 27 distinct main cards and archetype purity 38.6% (43 off-archetype copies); high slot dilution for a Synchro engine (Verified composition)
D11 Extra Deck Efficiency & Coverage 60 15-card Extra Deck with 14 Synchro and 1 Xyz; Synchro Overtake and Synchro extenders give coverage, but Kewl Tune boss copies are over the limit (Verified composition)
D12 Side Deck Adaptability 10 Side deck is empty (0 cards); no adaptability at all (Verified)
D13 Matchup Coverage & Format Fit 40 No dated metagame sample or tournament link; archetype share absent (Provisional)
D14 Pilotability & Error Tolerance 40 Multi-step Synchro chains with many Quick and once-per-turn decisions; heavy decision load (Inferred)

How the score was computed

Strategy profile: Combo. Structural ≈ 53, Going First ≈ 48, Going Second ≈ 56, Meta = provisional, Tournament Reliability ≈ 35. Modifiers: illegal copy-limit violations (-12); no side deck (-3). Final formula: Illegal list: normal formula 0.80*Structural(53) + 0.20*TournamentReliability(35) ≈ 49 is computed but NOT used; capped low to 30 per the Illegal rule (theoretical/structural only)

Probability & combo summary

  • Opening a starter: P(≥1) ≈ 0.25 · key two-card combo ≈ — · full-brick estimate ≈ 0.22 (all Inferred)
  • Combo output: best PowerIndex —, median —, board-per-starter —
  • Turn order: 0 going-first lines vs 0 going-second lines

Strengths

  • Dense Synchro engine with 14 Synchro Extra Deck slots and 14 Kewl Tune Tuner-chain cards
  • Strong negation package: Ash, Impermanence, Evenly Matched, Ghost Ogre, Effect Veiler, Droll & Lock Bird
  • High going-second hand-trap density

Weaknesses

  • Illegal as listed: copy limits exceeded on four cards
  • Only about 7 non-Tuner monsters in the 55-card main, causing Synchro bricks
  • No side deck
  • 43 off-archetype copies dilute the engine

Critical choke points

  • Non-Tuner availability for Synchro Summons (7 main-deck non-Tuners)
  • Kewl Tune Tuner count after hand traps are spent
  • Single-copy Limited boss/searcher cards (Cue, Reco, Synchro) that must be cut to legal counts
Priority Remove Add Reason
1 1 copy each of Kewl Tune Cue, Kewl Tune Synchro and Kewl Tune Reco (x2 removed) non-Tuner monsters or a single legal copy of each core Kewl Tune card Restores legality and the non-Tuner count needed for Synchro Summons
2 1 copy of Ash Blossom & Joyous Spring an alternate hand trap or a second Kewl Tune Tuner Semi-Limited cap is 2 in OCG
3 off-archetype tech cards (Triple Tactics Thrust, Mannadium Reframing, Red Nova, Solemn Accusation) side deck (15 cards) containing targeted answers to the expected meta Provides the post-side plan and adaptability that the deck currently lacks

Evidence & confidence

  • Verified: Main 55, Extra 15, Side 0 counts; Copy-limit violations for Ash Blossom, Kewl Tune Cue, Kewl Tune Synchro, Kewl Tune Reco; Archetype purity 38.6% and card-type spread; Hand-trap/negation/searcher tags from card text
  • Inferred: Brick rate around 0.22 from Tuner-heavy composition; Going-second hand-trap coverage 0.93; Extra Deck ceiling of 2800–3500 ATK; Interaction strength from negation count
  • Provisional: Meta Power; Matchup fit (D13); Median output (D4)
  • Data gaps: Illegal list: no legal-copy correction is applied, so the score is theoretical only no combos supplied; floor, median and ceiling are text-only no tournament link; archetype meta-share and per-pilot match record absent no side deck, so post-side plan and D12 are unobservable usage_statistics flags Kewl Tune B2B, RS, Remix, Crackle and Track Maker as not in this deck although the card list includes them; treated as a data inconsistency and not used for scoring no win-rate telemetry; going-first/second and matchup rates unknown
