Deck — Deck Power Evaluation
Final Contextual Deck Power: 30/100 (±8 · Confidence: Medium)
| Overall score | Value |
|---|---|
| Structural Deck Power | 57 |
| Going First | 58 |
| Going Second | 62 |
| Meta Power | provisional |
| Tournament Reliability | 40 |
- Primary strategy: Midrange
- Secondary strategies: Stun
- Format: tcg
Legality
Main 55 / Extra 15 / Side 0 — status under the rules at evaluation time: Illegal. 9 violation(s).
Identity & game plan
- Win condition: Synchro Summon boss monsters (Kewl Tune B2B, Zalen, Visas Amritara, Ecclesia and the Dark Dragon, Super Starslayer TY-PHON) off a Kewl Tune Tuner base; Hand-trap-protected Synchro pressure: Effect Veiler, Ash Blossom, Ghost Belle and Infinite Impermanence keep the engine online through interaction
- Turn 1 (going first): Normal Summon a Kewl Tune Tuner (Cue or Clip), use its search or special-summon effect, then Synchro Summon a boss; hand traps are held back to protect the boss
- Turn 2 (going second): Respond to the opponent's board with hand traps (Ash Blossom, Effect Veiler, Ghost Belle, Infinite Impermanence, Droll and Lock Bird) and then build a Synchro board from the remaining hand
- Recovery: Tuner recursion through Kewl Tune Mix, Kewl Tune Reco and Track Maker from the Deck or GY; hand traps and Synchro Monsters in the GY are reused as materials
- After siding: Not evaluable: the deck runs no Side Deck, so there is no post-side plan
Why it scores here
The deck reliably opens a Tuner-based Synchro engine: P(at least one archetype core card in a 5-card opening hand) is about 0.69 and P(at least one searcher-text card) is about 0.83, so most hands can start a line (Inferred). It converts that start into Synchro bosses from a 15-card Extra Deck with strong ATK and Synchro coverage, and the 16 hand traps and 18 negation-text cards give it layered protection of the engine. Its floor is weaker than its ceiling because no recorded boards exist, so combo conversion and median output are text-only inferences and are scored conservatively. The score is capped at 30 because the list is Illegal: nine copy-limit and Forbidden-status violations, including Albion the Branded Dragon, Called by the Grave, Triple Tactics Talent and Kewl Tune Rotary. Popularity of the Kewl Tune theme did not earn points, and the score comes from the system's engine, interaction and closing power, not from averaging the individual card scores.
Dimension scores
| # | Dimension | Score | Evidence |
|---|---|---|---|
| D1 | Engine Accessibility & Consistency | 62 | P(at least one archetype core card in hand of 5) ≈ 0.69 and P(at least one searcher-text card) ≈ 0.83; two-card Tuner bootstrap (Inferred) |
| D2 | Opening-Hand Quality & Brick Management | 55 | 16 hand-trap and 19 tech cards compete for hand space; 25 Tuners raise brick risk on the Synchro side (Inferred) |
| D3 | Combo Conversion & Ceiling | 48 | No parseable recorded boards; ceiling inferred from Synchro bosses and Kewl Tune recursion in card text (Inferred) |
| D4 | Combo Floor & Median Output | 45 | No combo data, so median output is unmeasured and set conservatively from the 24 Kewl Tune cards' overlap and starter diversity (Inferred) |
| D5 | Interruption Resilience & Route Redundancy | 68 | 16 hand traps and multiple negation effects give redundant interruption answers and Tuner recursion from GY (Inferred) |
| D6 | Resource Economy, Recovery & Grind | 62 | Searchers and Tuner recursion (Kewl Tune Mix, Kewl Tune Reco, Track Maker) reuse materials; the GY is a real resource (Inferred) |
| D7 | End-Board & Interaction Quality | 64 | Interaction text: 28 removal and 18 negation effects; hand traps protect the board (Inferred semantic) |
| D8 | Going-Second & Board-Breaking Power | 62 | Hand traps are strong on the going-second turn (P(at least one hand trap in hand of 6) ≈ 0.89); going-second split not recorded (Inferred) |
| D9 | Offensive Pressure & Closing Power | 66 | Synchro bosses at ATK 2500 to 3200 (Kewl Tune B2B 3200, TY-PHON 2900, Zalen 2800); piercing and double attack text (Verified stats, Inferred pressure) |
| D10 | Main Deck Efficiency & Flexibility | 52 | 55 Main Deck cards with 27 distinct names, 0% exact archetype purity and 70 off-archetype copies; heavy interaction and tech slots dilute the engine (Verified composition) |
| D11 | Extra Deck Efficiency & Coverage | 60 | 13 Synchro, 1 Fusion, 1 XYZ in the Extra Deck; the Fusion slot (Albion) is Forbidden in this format (Verified legality) |
| D12 | Side Deck Adaptability | 15 | No Side Deck at all (0 cards), so there is no post-side plan (Verified composition) |
| D13 | Matchup Coverage & Format Fit | 50 | No tournament link or dated meta sample; Kewl Tune share unknown (Provisional) |
| D14 | Pilotability & Error Tolerance | 55 | Multi-step Tuner and Synchro sequencing with many hand-trap timing decisions; moderate decision load (Inferred) |
How the score was computed
Strategy profile: Midrange primary, Stun secondary; the Midrange profile was used as the sole weight set because the Stun profile was not blended. Structural ≈ 57, Going First ≈ 58, Going Second ≈ 62, Meta = provisional, Tournament Reliability ≈ 40. Modifiers: banlist exposure (-12). Final formula: No reliable metagame: 0.80*Structural + 0.20*TournamentReliability = 0.80*57 + 0.20*40 = 53.6; banlist modifier -12 gives 41.6; capped at 30 because the deck is Illegal (copy limits and Forbidden cards). Meta Power is provisional.
Probability & combo summary
- Opening a starter: P(≥1) ≈ 0.69 · 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
- Layered hand-trap and negation coverage (16 hand traps, 18 negation-text cards)
- Strong Synchro boss pool with ATK 2500 to 3200 and Tuner recursion
- Searcher-text density gives a high chance of a functional opening hand
Weaknesses
- Illegal list: copy-limit violations and four Forbidden cards
- No Side Deck, so no best-of-3 adaptability
- No recorded boards, so combo floor and median are unmeasured
Critical choke points
- Kewl Tune Tuner base: most Synchro lines need a Kewl Tune Tuner in hand or GY
- Albion the Branded Dragon is the only Fusion in the Extra Deck and is Forbidden, so Fusion access is lost once it is removed
Recommended changes
| Priority | Remove | Add | Reason |
|---|---|---|---|
| 1 | Albion the Branded Dragon, Called by the Grave, Triple Tactics Talent, Kewl Tune Rotary (all Forbidden) | Legal Synchro Tuners and Tuner-search replacements | Forbidden cards make the list Illegal and remove most of the score ceiling |
| 2 | Excess copies of Kewl Tune Cue, Kewl Tune Synchro, Kewl Tune Reco, Droll & Lock Bird, Ash Blossom & Joyous Spring | Single copies of Limited cards and the allowed copy count of Semi-Limited cards | Brings the copy histogram within each banlist limit |
| 3 | Nothing; the Side Deck is empty | Up to 15 Side Deck cards for the matchups being played | Lifts D12 from 15 and gives a post-side plan for best-of-3 |
Evidence & confidence
- Verified: Legality: Illegal, with 9 copy-limit violations and 4 Forbidden cards in the Main Deck; Main 55, Extra 15, Side 0; within size rules; Synchro boss stats and hand-trap text from the card data
- Observed: Archetype usage: Kewl Tune core cards appear in 100% of archetype stat rows; Ash Blossom and Called by the Grave are core
- Inferred: Opening-hand consistency: P(at least one archetype core card) ≈ 0.69, P(searcher text) ≈ 0.83, P(hand trap in going-second hand) ≈ 0.89; Interaction and resilience scores from hand-trap and negation text counts; Going-first and going-second power from text-only plans
- Provisional: Meta Power (null) and matchup fit (D13 = 50): no dated metagame sample or tournament link; Tournament reliability uses the illegal-list penalty and no match data
- 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 No win-rate telemetry for going-first, going-second, matchup or brick rate No Side Deck: post-side plan cannot be evaluated Meta Power is Provisional without a dated metagame sample
