Legality

Main 40 / Extra 15 / Side 0 — status under the rules at evaluation time: Illegal. 2 violation(s).

Identity & game plan

  • Win condition: Synchro Summon Kewl Tune Synchro-family boss monsters (Kewl Tune RS, Kewl Tune Remix, Kewl Tune Track Maker, Visas Amritara, Baronne de Fleur) off Tuner-heavy boards, then pressure with Tuner-based negation and removal; Interaction-led control through hand traps (Ash Blossom, Ghost Belle, Effect Veiler, Infinite Impermanence, Maxx C) that lock out the opponent's Tuner and effect plays
  • Turn 1 (going first): Normal Summon a Kewl Tune Tuner, use Kewl Tune Mix / Reco / Cue search effects into a Synchro Summon, and rely on the archetype core to keep a second Tuner live
  • Turn 2 (going second): Hold hand traps to negate the opponent's starter and then convert the six-card hand into a Synchro Summon on the next turn
  • Recovery: Kewl Tune Synchro and Duelist Genesis search Synchro Spell/Traps and Kewl Tune monsters from the Deck, and Kewl Tune Reco and Mix recur Tuners from the Graveyard
  • After siding: No Side Deck is registered, so there is no post-side plan; the deck is evaluated as a single structural list

Why it scores here

This list scores as a structural system, not as an average of its cards. Its engine is accessible: the Kewl Tune core is present in 28 copies and P(at least one core card in a 5-card opening hand) is about 0.999 (Inferred), and the Tuner density gives multiple starting routes. The interaction suite (13 hand traps, 12 negation-text cards) is broad and lets it play through disruption and win on the second turn. The score is held down by the combo evidence: the best recorded line reaches only PowerIndex 11, the median is 9, and no board or boss data exists, so the ceiling and floor both read low. The deck is also Illegal in its format (Synchro Overtake is Forbidden and Kewl Tune Cue is run at 2 copies against a limit of 1), which caps it to a theoretical, structural-only score. Popularity in the archetype did not earn points, and no points were given for meta share.

Dimension scores

# Dimension Score Evidence
D1 Engine Accessibility & Consistency 60 Archetype core present in 28 copies, P(at least one core card in a 5-card hand) ≈ 0.999; starter-specific odds for 2-copy starters ≈ 0.24 in a 5-card hand (Inferred)
D2 Opening-Hand Quality & Brick Management 55 13 hand traps and 15 Tuners give a functional mix, but several Tuners are Synchro-material-dependent and can be dead in the hand without a second Tuner (Inferred)
D3 Combo Conversion & Ceiling 25 Best recorded line is PowerIndex 11 with board 0 and endMonsters 0; ceiling is low on recorded data (Observed, thin sample of 3 combos)
D4 Combo Floor & Median Output 20 Median PowerIndex 9 across 3 scored combos and no going-first/second split; floor is low (Observed)
D5 Interruption Resilience & Route Redundancy 60 Five independent hand traps and multiple Tuner recursion routes allow continuing after one interruption (Inferred)
D6 Resource Economy, Recovery & Grind 45 Average end-hand 1 card with no GY or banish resource signature recorded; recursion exists only in card text (Observed/Inferred)
D7 End-Board & Interaction Quality 60 13 hand traps, 12 negation-text cards and 13 removal-text cards; measured interaction density is 0 in the recorded boards, so the score relies on text read (Inferred)
D8 Going-Second & Board-Breaking Power 60 Hand-trap-heavy going-second plan with 92% chance of at least one hand trap in a 6-card hand (Inferred); no going-second combo data
D9 Offensive Pressure & Closing Power 40 No recorded end-board ATK or boss counts; closing power relies on Synchro bosses from card text (Inferred)
D10 Main Deck Efficiency & Flexibility 62 21 distinct main cards in 40 slots with 14 non-Tuner spells and traps and 15 Synchro in the Extra Deck; compact and coherent but 3-copy stacks reduce flexibility (Inferred)
D11 Extra Deck Efficiency & Coverage 60 All 15 Extra Deck slots are Synchro, with multiple Kewl Tune Synchro bosses; coverage is good but many slots are archetype-specific (Verified/Inferred)
D12 Side Deck Adaptability 10 No Side Deck is registered (Side Deck size 0); adaptability cannot be measured (Verified)
D13 Matchup Coverage & Format Fit 45 No tournament link and no dated meta sample; archetype meta-share is absent, so this is provisional
D14 Pilotability & Error Tolerance 60 Multi-step Synchro lines with many Tuner-material decisions and hand-trap timing; high execution load (Inferred)

How the score was computed

Strategy profile: Combo. Structural ≈ 48.5, Going First ≈ 45, Going Second ≈ 55, Meta = provisional, Tournament Reliability ≈ 45. Modifiers: banlist exposure (-8). Final formula: Illegal deck: theoretical/structural-only. Final = 0.80*Structural + 0.20*TournamentReliability + ContextModifiers (Meta provisional) = 0.80*48.5 + 0.20*45 - 8 ≈ 40

Probability & combo summary

  • Opening a starter: P(≥1) ≈ 1 · key two-card combo ≈ — · full-brick estimate ≈ — (all Inferred)
  • Combo output: best PowerIndex 11, median 9, board-per-starter 0
  • Turn order: 0 going-first lines vs 0 going-second lines

Strengths

  • Accessible Kewl Tune engine with 28 core copies and very high chance of a core card in the opening hand
  • Broad hand-trap and negation suite (13 hand traps) that gives strong going-second interaction
  • Compact main with a full 15-card Synchro Extra Deck

Weaknesses

  • Illegal as built: Synchro Overtake is Forbidden and Kewl Tune Cue is over its copy limit
  • Recorded combo ceiling is low (best PowerIndex 11, median 9)
  • No Side Deck, so no post-side adaptation
  • Low exact-name archetype purity (38%) with many off-archetype cards

Critical choke points

  • Forbidden Synchro Overtake must be removed before the list is legal
  • Tuner-material requirements mean a hand without a second Tuner can stall the Synchro line
Priority Remove Add Reason
1 Synchro Overtake (1 copy, Forbidden) A legal Kewl Tune searcher or Tuner, or a second Duelist Genesis-compatible card The list cannot be played in master-duel as built; this removes the illegal card
2 One copy of Kewl Tune Cue (2 copies run, Limited to 1) A legal Tuner or a second copy of an unlimited Kewl Tune card Fixes the copy-limit violation without changing the core engine
3 Reinforcement of the Army (Limited, 1 copy) A Side Deck-compatible card or an extra Kewl Tune Tuner Adds one searcher slot toward consistency and creates the first Side Deck option

Evidence & confidence

  • Verified: Legality: Synchro Overtake Forbidden; Kewl Tune Cue over limit (Limited to 1, run at 2); Main 40 / Extra 15 / Side 0; Synchro Extra Deck only; Core archetype presence: 28 copies; No tournament link and no side deck
  • Observed: Best recorded combo PowerIndex 11, median 9, from 3 scored combos; Average end-hand 1 card, no GY or banish resource recorded
  • Inferred: Starter probability ≈ 0.999 for the core group; Hand-trap coverage 92% in a 6-card hand (going second); Brick and Tuner-material risk estimated from composition
  • Provisional: Meta Power is null and D13 is provisional: no dated metagame sample exists
  • Data gaps: no tournament link: archetype meta-share and per-pilot match record absent no win-rate telemetry: going-first/second, matchup and brick/starter rates are Inferred combo sample is thin (3 scored lines, no going-first or going-second split, no board data) no Side Deck registered, so post-side adaptability cannot be measured Meta Power is provisional until a dated metagame sample is supplied
