Legality
Main 43 / Extra 16 / Side 0 — status under the rules at evaluation time: Illegal. 9 violation(s).
Identity & game plan
- Win condition: Synchro Summon through Kewl Tune Tuner chains into high-ATK boss monsters such as Kewl Tune B2B, Junora and Elfnote June Pride; Elfnote Seraphim Strelitzia and Accel Synchro Stardust Dragon as additional Extra Deck boards
- Turn 1 (going first): Normal Summon a Tuner (Kewl Tune Cue or Reco) and use its search or Special Summon to set up a Synchro Summon with a second Tuner; the Kewl Tune Synchro spell is the main searcher for the Synchro Tuner
- Turn 2 (going second): Open with Ash Blossom, Ghost Ogre, Effect Veiler or Droll & Lock Bird as interaction, then rebuild a board through Synchro Summons from the 6-card hand
- Recovery: Duelist Genesis and Synchro Overtake re-fetch a Synchro Tuner or Synchro Monster; Kewl Tune Mix and Reco recur Kewl Tune monsters from the GY
- After siding: No Side Deck is registered, so there is no post-side plan
Why it scores here
The deck's Synchro engine is built around the Kewl Tune chain: a Tuner-heavy Main Deck (about 88% of the core archetype group present in at least one opening hand of five, Inferred) feeds 16 Synchro Extra Deck monsters, so the list reliably finds a Tuner and reaches a Synchro Summon. The conversion ceiling comes from the Synchro bosses, while the median is lower because many of the Main Deck pieces are Tuners and searchers that need a second Tuner before they do anything. Interaction is real but thin, with about 13 hand traps and negation effects (Inferred from text), and there is no board breaker or floodgate. It has no Side Deck and runs two Forbidden cards plus several over-limit Limited and Semi-Limited copies, so it cannot be played as listed. Popularity and archetype usage were not counted toward the score, and card scores were not averaged; the score comes from the system's consistency and output, then is capped low because the list is illegal.
Dimension scores
| # | Dimension | Score | Evidence |
|---|---|---|---|
| D1 | Engine Accessibility & Consistency | 70 | P(at least one archetype core card in a 5-card opening hand) ≈ 0.88; 14 core copies; 2-card bootstrap via Tuner search (Inferred) |
| D2 | Opening-Hand Quality & Brick Management | 60 | Searcher text in 20 Main Deck copies gives P ≥ 0.97 for a search hand; brick risk comes from Tuner-only hands with no second Tuner (Inferred) |
| D3 | Combo Conversion & Ceiling | 55 | No recorded boards; ceiling is inferred from Synchro boss text such as Kewl Tune B2B and Junora (Inferred) |
| D4 | Combo Floor & Median Output | 45 | Median output is inferred to be lower than the ceiling because most Synchro lines need two Tuners and a specific boss; no power distribution exists (Inferred) |
| D5 | Interruption Resilience & Route Redundancy | 55 | Ash Blossom, Effect Veiler, Ghost Belle and Ghost Ogre give several independent answers, and Kewl Tune Mix and Reco recur Tuners (Inferred from text) |
| D6 | Resource Economy, Recovery & Grind | 50 | Duelist Genesis, Synchro Overtake and Kewl Tune Mix/Reco provide some recursion; no resource telemetry exists (Inferred) |
| D7 | End-Board & Interaction Quality | 50 | 13 hand traps and 8 negation texts, plus Kewl Tune Loudness War and Zalen for removal and negation; no faceDownST or boss-protection data (Inferred) |
| D8 | Going-Second & Board-Breaking Power | 40 | Going-second plan relies on hand-trap interaction before a Synchro board; no board breaker in the Main Deck (Inferred) |
| D9 | Offensive Pressure & Closing Power | 45 | Boss ATK reaches 3100–3200 (Junora, June Pride, B2B) but the lines are single-boss and no recorded attacks exist (Inferred) |
| D10 | Main Deck Efficiency & Flexibility | 55 | 43 Main Deck cards with 21 distinct names, about 33 Tuners and only a few dead slots; size is legal (Verified) |
| D11 | Extra Deck Efficiency & Coverage | 45 | 16 Extra Deck cards exceed the 15-card cap; the extra Synchro is a flex slot (Verified) |
| D12 | Side Deck Adaptability | 20 | No Side Deck was registered; post-side adaptability cannot be assessed (Provisional) |
| D13 | Matchup Coverage & Format Fit | 50 | Archetype meta-share and tournament data are absent; no dated meta sample (Provisional) |
| D14 | Pilotability & Error Tolerance | 40 | Multi-step Synchro lines with Tuner chains and several search effects require careful sequencing; this is a high decision burden (Inferred) |
How the score was computed
Strategy profile: Combo. Structural ≈ 53, Going First ≈ 50, Going Second ≈ 45, Meta = provisional, Tournament Reliability ≈ 45. Modifiers: banlist exposure (-8); extra_deck_over_cap (-2); side_deck_absent (-2). Final formula: Illegal cap applied: uncapped 0.80*53 + 0.20*45 = 51.4, then modifiers (-12 total) give 39, which is capped to 20 because the list runs Forbidden cards and 16 Extra Deck cards. Theoretical/structural only.
Probability & combo summary
- Opening a starter: P(≥1) ≈ 0.97 · 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
- Dense Tuner and searcher package gives a high chance of a live opening hand (Inferred)
- Large Synchro Extra Deck gives several boss options (Verified)
- Multiple hand traps and negation texts give layered interaction (Inferred)
Weaknesses
- Illegal as listed: two Forbidden cards and several over-limit copies (Verified)
- Extra Deck is one card over the limit (Verified)
- No Side Deck, so no adaptability (Verified)
- No recorded boards, so the combo ceiling and median are text-only (Verified)
Critical choke points
- Kewl Tune Synchro and the Tuner search chain: losing it or its Tuner leaves the Synchro plan stalled (Inferred)
- Reliance on Kewl Tune Cue and Reco as Tuners, which become scarce after the legal copy limits are applied (Inferred)
Recommended changes
| Priority | Remove | Add | Reason |
|---|---|---|---|
| 1 | Kewl Tune Rotary (1) and PSY-Framelord Omega (1) | Legal replacement Tuner and Synchro cards, or leave empty | Forbidden cards make the list illegal in TCG |
| 2 | Copies over the limit: Elfnote Lucina 3→1, Elfnote Tinia 3→1, Kewl Tune Synchro 3→1, Kewl Tune Cue 2→1, Kewl Tune Reco 2→1, Ash Blossom 3→2 | Replacement non-limited cards | Brings each card within its legal copy limit |
| 3 | One Extra Deck card | None | Extra Deck 16 is over the 15-card limit |
| 4 | A Side Deck of 0 to 15 cards | Adds post-side adaptability, which is currently absent |
Evidence & confidence
- Verified: Legality: Illegal, with Forbidden, Limited and Semi-Limited violations; Main Deck 43 cards in the legal 40–60 range; Archetype core group present at 14 copies
- Inferred: Opening-hand consistency probabilities; Ceiling and median from card text alone; Interaction density from text; Going-first and going-second estimates
- Provisional: Meta Power is null because no dated metagame sample exists; Matchup and format fit cannot be assessed
- Data gaps: no combos supplied; combo floor/median/ceiling is text-only inference no tournament link; archetype meta-share and per-pilot record absent no win-rate telemetry; going-first/second, matchup and brick rates are Inferred or Unknown no Side Deck registered Meta Power is Provisional unless a dated metagame sample is supplied
