Legality
Main 54 / Extra 15 / Side 0 — status under the rules at evaluation time: Illegal. 3 violation(s).
Identity & game plan
- Win condition: Xyz/Link boss pressure from the Extra Deck (K9-X Werewolf, Divine Arsenal AA-ZEUS, Caesar Valius-style Vanquish Soul beaters), with no confirmed recorded board to verify the line; Vanquish Soul Special Summon chains through revealed Attribute monsters
- Turn 1 (going first): Normal Summon a searcher-backed starter (Vanquish Soul Dr. Mad Love, Mulcharmy Fuwalos or K9 Izuna), search a second piece, and build toward a Xyz boss; Inferred from card text only
- Turn 2 (going second): Hold hand traps (Ash Blossom, Ghost Belle, Nibiru, Droll & Lock Bird) and interrupt the opponent's first engine before committing a boss; Inferred
- Recovery: Search or revive through Vanquish Soul, Start! and K9 searchers; Inferred
- After siding: None: the Side Deck is empty, so there is no post-side plan
Why it scores here
The deck is Illegal: three cards exceed their OCG copy limits (Ash Blossom and K9-17 Izuna at 3 copies, Vanquish Soul Razen at 3 against a limit of 1), so it receives a capped, structural-only score and no normal final rating. The system reads as a fragmented Toolbox: it opens searchers reliably (P(at least one searcher in a 5-card hand) about 0.90, Inferred) and runs 10 hand traps and 6 negation texts, which gives it real interruption resilience and going-second value. Its closing power comes from high-ATK Xyz and Link bosses such as K9-X Werewolf and Divine Arsenal AA-ZEUS. Against that, the Umbral Horror label is not supported by the list: exact-name purity is 1.4%, with the cards spread across Vanquish Soul, K9, Mulcharmy, Gravekeeper's and Bystial, and the archetype's core Umbral cards are absent. No recorded boards exist, so the ceiling and median are text-only inferences. Popularity did not earn points, and card scores were not averaged into the deck score.
Dimension scores
| # | Dimension | Score | Evidence |
|---|---|---|---|
| D1 | Engine Accessibility & Consistency | 58 | P(at least one searcher in a 5-card opening hand) about 0.90; archetype core group only 0.515 per hand (Inferred) |
| D2 | Opening-Hand Quality & Brick Management | 50 | 10 hand traps and 14 tech cards in a 54-card main, so some hands will be dead against a non-interaction opponent (Inferred) |
| D3 | Combo Conversion & Ceiling | 40 | No parseable boards; ceiling is a text-only read of Xyz and Link bosses (Inferred) |
| D4 | Combo Floor & Median Output | 35 | combos_evidence total 0 and no median power index; floor is unmeasurable here (Provisional) |
| D5 | Interruption Resilience & Route Redundancy | 60 | Ten hand traps across several interruption types and a searcher redundancy base (Inferred) |
| D6 | Resource Economy, Recovery & Grind | 55 | Xyz materials and the Extra Deck supply resources, but the grind has no measured data (Inferred) |
| D7 | End-Board & Interaction Quality | 52 | Limited interaction: Ash, Ghost Belle, Droll and Nibiru are hand-based; Gravekeeper's and Dimensional Fissure are the only backrow answers (Inferred) |
| D8 | Going-Second & Board-Breaking Power | 58 | Going-second hand-trap probability 0.73 for at least one hand trap in 6 cards (Inferred) |
| D9 | Offensive Pressure & Closing Power | 62 | Bosses with 2700 to 3300 ATK (K9-X Werewolf, Divine Arsenal AA-ZEUS, Super Starslayer TY-PHON) (Verified card text) |
| D10 | Main Deck Efficiency & Flexibility | 38 | 54 main cards with 1.4% exact-archetype purity and 68 off-archetype copies, so the list lacks coherence (Verified) |
| D11 | Extra Deck Efficiency & Coverage | 45 | 15 Extra slots filled with 12 Xyz and 3 Link across many sub-archetypes, without the archetype core (Verified structure, Inferred) |
| D12 | Side Deck Adaptability | 15 | Side Deck is empty (0 cards), so there is no post-side adaptation (Verified) |
| D13 | Matchup Coverage & Format Fit | 45 | No tournament or metagame sample; only archetype usage stats (Provisional) |
| D14 | Pilotability & Error Tolerance | 40 | Multi-step Xyz and Link chains across several sub-archetypes with many decision points (Inferred) |
How the score was computed
Strategy profile: Toolbox. Structural ≈ 49, Going First ≈ 46, Going Second ≈ 52, Meta = provisional, Tournament Reliability ≈ 42. Modifiers: banlist_exposure (-8); engine_conflicts (-4). Final formula: Illegal cap: 0.80*49 + 0.20*42 = 47.6, plus modifiers -12 = 35.6, capped to 30; structural-only, no normal final score (Meta provisional)
