Identity & game plan
- Win condition: Synchro Summon Kewl Tune boss monsters (B2B, Loudness War, Remix, Track Maker) off a Tuner-based starter, with hand traps protecting the line; Ecclesia and the Dark Dragon and Albion via Fusion/Synchro follow-up from the Extra Deck
- Turn 1 (going first): Search or draw a Kewl Tune Tuner starter (Mix, Reco, Synchro, JJ), Normal Summon a Tuner, Synchro Summon, and keep hand traps for the opponent's turn
- Turn 2 (going second): Hold 1-2 hand traps (Ash Blossom, Ghost Ogre, Ghost Belle, Effect Veiler, Maxx C, Kewl Tune Clip) to stop the opponent's starter, then rebuild through GY Tuner recursion
- Recovery: Tuners recycle from the GY through Mix, Remix, Track Maker and Rotary effects; Crossout Designator and Loudness War provide protection and interaction
- After siding: No side deck is registered (0 side cards), so no post-side plan is evidenced
Why it scores here
The deck's 40-card Main Deck is a Tuner-dense Synchro engine: 23 Tuner monsters, 12 Synchro Tuners, 15 searcher-text cards and 13 hand traps, so it reliably opens a live starter (the archetype core group proxy is about 99.7% in a five-card hand, and a searcher is at least once in about 92% of opening hands; Inferred). Its strongest signal is going-second interaction (roughly 92% to see a hand trap in a six-card hand; Inferred), which lets the list stop the opponent's first board and then rebuild through GY Tuner recursion. Offensive closing comes from the Extra Deck bosses (B2B, Loudness War, Remix), but no recorded boards exist, so the ceiling and floor are text-based inference and the median is held near the middle. Scores reflect consistency, redundancy and interaction on the system as a whole, not an average of card scores, and not the guide's claim that this is the strongest deck in the current meta, which is not verified and did not add points. Lack of any side deck and the absence of tournament or win-rate data cap the result.
Dimension scores
| # | Dimension | Score | Evidence |
|---|---|---|---|
| D1 | Engine Accessibility & Consistency | 75 | P(at least 1 searcher in 5-card hand) about 0.92; archetype core proxy 0.997; 2-copy starters about 0.24 per hand (Inferred) |
| D2 | Opening-Hand Quality & Brick Management | 62 | 13 hand traps and 14 Tuner tech cards give redundancy, but many are dead without a Tuner or an opposing action, so brick risk is moderate (Inferred) |
| D3 | Combo Conversion & Ceiling | 65 | No parseable boards; ceiling read from card text: B2B, Loudness War and Remix with GY Tuner recursion (Inferred semantic) |
| D4 | Combo Floor & Median Output | 55 | combos_evidence total_combos 0; floor and median set near the middle with no observed boards (Inferred, low sample) |
| D5 | Interruption Resilience & Route Redundancy | 72 | Multiple hand-trap and Tuner starter lines plus GY recursion give independent routes after one interruption (Inferred) |
| D6 | Resource Economy, Recovery & Grind | 66 | Tuner recursion via Mix, Remix, Track Maker and Rotary reclaims resources; no measured net advantage (Inferred from text) |
| D7 | End-Board & Interaction Quality | 70 | Negation and removal text on about 11 negation and 18 removal cards, plus Crossout Designator and Loudness War protection (Inferred semantic) |
| D8 | Going-Second & Board-Breaking Power | 75 | Going-second hand-trap coverage about 0.92 in a six-card hand, with Ghost and Ash hand traps for board breaking (Inferred) |
| D9 | Offensive Pressure & Closing Power | 62 | Extra Deck bosses B2B 3200 ATK and Loudness War 3000 DEF; closing relies on Synchro follow-up, not verified pressure data (Verified stats, Inferred closing) |
| D10 | Main Deck Efficiency & Flexibility | 60 | 40 Main Deck cards with 20 distinct names; a 40-card minimum with 3-copy staples keeps the engine compact (Verified composition, Inferred efficiency) |
| D11 | Extra Deck Efficiency & Coverage | 65 | 15 Extra Deck cards, 14 Synchro, 1 Fusion; flexible Synchro coverage with Albion as the only Fusion (Verified composition) |
| D12 | Side Deck Adaptability | 25 | Side deck is empty (0 side cards), so there is no post-side adaptability to evaluate (Verified, score penalised) |
| D13 | Matchup Coverage & Format Fit | 50 | No tournament link and no dated meta sample; archetype usage stats only (Provisional) |
| D14 | Pilotability & Error Tolerance | 40 | Hand-trap timing, Tuner choices and multi-step Synchro lines raise decision load (Inferred) |
How the score was computed
Strategy profile: Combo. Structural ≈ 66, Going First ≈ 60, Going Second ≈ 72, Meta = provisional, Tournament Reliability ≈ 58. Modifiers: no side deck (-2); banlist exposure (-1). Final formula: 0.80*Structural + 0.20*TournamentReliability + ContextModifiers (Meta provisional; Structural meta-neutral with D13 dropped and weights renormalised)
Probability & combo summary
- Opening a starter: P(≥1) ≈ 0.92 · key two-card combo ≈ — · full-brick estimate ≈ 0 (all Inferred)
- Combo output: best PowerIndex —, median —, board-per-starter —
- Turn order: 0 going-first lines vs 0 going-second lines
Strengths
- Redundant Tuner starters and searchers give high opening-hand access (Inferred)
- Going-second hand-trap density (about 0.92 in a six-card hand) (Inferred)
- GY Tuner recursion gives a rebuild route after interaction (Inferred)
Weaknesses
- No side deck, so no post-side adaptability (Verified)
- Low measured combo data: no recorded boards to confirm the ceiling (Verified gap)
- High pilot load from hand-trap timing and Tuner choices (Inferred)
Critical choke points
- Kewl Tune Tuner starter access, though redundant, funnels through a small set of Tuner and searcher cards
- Extra Deck bosses depend on Synchro material supplied by the Tuner engine
Recommended changes
| Priority | Remove | Add | Reason |
|---|---|---|---|
| 1 | Side deck of up to 15 cards | The list registers no side cards, so it has no post-side plan; a side deck would address the hand-trap-heavy and floodgate matchups the main deck cannot cover (Verified legality, Inferred) |
Evidence & confidence
- Verified: Legal in master-duel: 40 Main, 15 Extra, 0 Side within size rules; Nine restricted cards (Limited/Semi-Limited) within legal copy counts; Archetype exact-name purity 36.4% with sub-archetype spread; Usage stats: 14 of 25 core cards present (56%)
- Inferred: Opening-hand access: searcher about 0.92, archetype core proxy 0.997; Going-second hand-trap coverage about 0.92; Interaction density and Tuner recursion from card text; Ceiling and floor from text only; no recorded boards
- Provisional: Matchup and format fit (D13) without a dated meta sample; Meta Power (null)
- 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 absent no win-rate telemetry (going-first/second, matchup, brick and starter rates) Meta Power is Provisional without a dated metagame sample no side deck registered, so post-side performance cannot be assessed
