Identity & game plan
- Win condition: K9 Xyz and Vanquish Soul boss monsters (K9-X Werewolf 3300 ATK, Vanquish Soul Caesar Valius 3000 ATK, Jacks 2600 ATK) converting a stable board; Vanquish Soul Heavy Borger and Caesar Valius recursion/draw, backed by Rock of the Vanquisher link pressure
- Turn 1 (going first): Open a hand with a K9 or Vanquish Soul searcher and a hand-revealed Special Summon, then build a boss via Xyz/Link, holding Ash Blossom, Ghost Belle or Droll for the opponent's first answer
- Turn 2 (going second): Use hand traps (Ash Blossom, Ghost Belle, Droll & Lock Bird, Maxx "C", D.D. Crow) to break the opponent's opening, then K9 Normal Summons (opponent holds 2+ cards) into a Xyz
- Recovery: Search again through the 16 searcher-text cards (A Case for K9, Vanquish Soul, Start!, Razen, Hollie Sue) and rebuild from the Deck; Forced Release and Lupis extend the board after removal
- After siding: No side deck is run (0 side cards); this is a single-game format, so there is no post-side plan to evaluate
Why it scores here
The deck opens reliably: the K9 archetype core has an estimated 98.7% chance of at least one card in a 5-card hand, and 16 searcher-text cards give about 93.5% odds of a searcher in hand, so starter access is strong even though the engine is split across two archetypes. Its interaction is the main strength, with 8 hand traps, 5 negation-text cards and 11 removal-text cards, which gives it a good chance of answering the opponent's first play on the draw. Boss monsters with 2600 to 3300 ATK and Link pressure give it closing power. The score is held back by the split engine (K9 is only 14 of 55 archetype-tagged copies, with 18 Vanquish Soul copies), the lack of recorded boards for a combo ceiling or median, and the absence of any tournament or win-rate data. Popularity and meta share did not earn points, and card scores were not averaged into the deck score.
Dimension scores
| # | Dimension | Score | Evidence |
|---|---|---|---|
| D1 | Engine Accessibility & Consistency | 70 | P(>=1 K9 core card in 5-card hand) ≈ 0.987 and P(>=1 searcher in hand) ≈ 0.935; the split between two engines lowers the chance that a specific starter is live (Inferred) |
| D2 | Opening-Hand Quality & Brick Management | 62 | 16 searchers and 22 core-group copies keep hands functional, but 8 hand traps and two engines that need different hand reveals create dead or conflicting draws (Inferred) |
| D3 | Combo Conversion & Ceiling | 60 | No recorded boards exist, so the ceiling rests on card text such as Forced Release, Lupis, Jacks and Werewolf (Inferred, text-only) |
| D4 | Combo Floor & Median Output | 50 | No recorded boards exist, so the median is unmeasured and set to a neutral score (Provisional) |
| D5 | Interruption Resilience & Route Redundancy | 70 | Ash Blossom, Ghost Belle, Droll, Maxx "C" and Crossout Designator give several independent answers, and Vanquish Soul returns monsters to hand to re-summon (Inferred) |
| D6 | Resource Economy, Recovery & Grind | 72 | Searcher density plus Heavy Borger and Maxx "C" draw effects give good card flow for grind (Inferred from card text) |
| D7 | End-Board & Interaction Quality | 74 | removal_text 11, negation_text 5, hand trap 8; Jacks and Ripper add on-field removal and negation (Inferred from card text and role flags) |
| D8 | Going-Second & Board-Breaking Power | 68 | P(>=1 hand trap in 6-card going-second hand) ≈ 0.764, plus Crossout Designator and Vallon-style removal text (Inferred) |
| D9 | Offensive Pressure & Closing Power | 72 | Boss ATK of 3300 (Werewolf), 3000 (Caesar Valius, AA-ZEUS), 2600 (Jacks) and 2300 (Lupis) gives strong closing power (Verified stat / Inferred) |
| D10 | Main Deck Efficiency & Flexibility | 62 | Exactly 40 main slots with 25 distinct cards, but 9 tech cards and 41 off-exact-name copies dilute the engine (Inferred) |
| D11 | Extra Deck Efficiency & Coverage | 66 | Full 15-card Extra with 14 distinct cards, including 3 K9 Xyz and 2 Rock of the Vanquisher, gives broad coverage (Verified composition) |
| D12 | Side Deck Adaptability | 40 | No side deck is run in a single-game format, so there is no post-side plan to score (Provisional) |
| D13 | Matchup Coverage & Format Fit | 50 | No tournament link, archetype meta-share or matchup record is present, so format fit is unmeasured (Provisional) |
| D14 | Pilotability & Error Tolerance | 50 | Several hand-reveal and quick-effect timings across two archetypes raise decision load, with no step-by-step combo data (Inferred) |
How the score was computed
Strategy profile: Midrange. Structural ≈ 64.3, Going First ≈ 65, Going Second ≈ 67, Meta = provisional, Tournament Reliability ≈ 62. Modifiers: engine conflict (-3); banlist exposure (-1). Final formula: 0.80*Structural + 0.20*TournamentReliability + ContextModifiers (Meta provisional; no dated metagame sample)
