Legality
Main 57 / Extra 15 / Side 0 — status under the rules at evaluation time: Illegal. 4 violation(s).
Identity & game plan
- Win condition: Xyz boss monsters (Number C104: Umbral Horror Masquerade 3000 ATK, Ryzeal Detonator 3000 ATK) reached through Umbral Horror and Mulcharmy card advantage plus Xyz chains; Ryzeal Duo Drive and Mereologic Aggregator as single-threat closers after the board is established
- Turn 1 (going first): Open on Umbral Horror / V Umbral Horror / Mulcharmy draw engines, use Barian's Seventh Untopia to search Umbral Horror, and hold Ash Blossom or Infinite Impermanence for the first opposing response (Inferred from card text)
- Turn 2 (going second): Hold Ash Blossom, Ghost Ogre & Snow Rabbit, Droll & Lock Bird and Nibiru as hand traps to break the opponent's first board, then rebuild through Mulcharmy draws (Inferred)
- Recovery: Mulcharmy draw effects and Barian's Hope / Seventh Ascension searches rebuild hand after an interruption; Ryzeal Cross recycles Ryzeal GY monsters (Inferred)
- After siding: No side deck is registered, so there is no post-side plan; the deck cannot adjust to matchups
Why it scores here
The deck's Umbral Horror core is reliably accessible: the hypergeometric estimate gives about a 93% chance of at least one core card in a 5-card opening hand, and the Mulcharmy and Barian's searchers add card flow, so it usually reaches a live engine by turn 2 (Inferred). Its interaction density is the strongest part of the system: 12 hand traps, Ash Blossom, Infinite Impermanence, Droll & Lock Bird, Ghost Ogre and Nibiru, plus Number 104-style negations and Ryzeal Detonator removal, give it real going-second pressure. The score is held down by four cards run over their copy limits (making the list illegal), a main deck that mixes Umbral Horror, Ryzeal, Mulcharmy, Barian's, Seventh and Masquerade pieces (exact-name archetype purity 13.9%), and no side deck. The combo evidence is empty, so ceiling and floor are text-only inference. Popularity and archetype usage were not credited as power, and the score was not derived by averaging the card scores.
Dimension scores
| # | Dimension | Score | Evidence |
|---|---|---|---|
| D1 | Engine Accessibility & Consistency | 62 | P(>=1 Umbral core card in 5-card hand) ≈ 0.93; 2-card starter bootstrap is plausible but split across several sub-archetypes (Inferred) |
| D2 | Opening-Hand Quality & Brick Management | 50 | Hand traps and Xyz-only pieces (Ryzeal, Masquerade, Number) are dead without a live engine, and 6 singletons plus several off-plan 1-copy cards add brick risk; Mulcharmy partly mitigates (Inferred) |
| D3 | Combo Conversion & Ceiling | 58 | No recorded boards; the Umbral to Masquerade to Number C104 path is text-supported but unverified (Inferred) |
| D4 | Combo Floor & Median Output | 45 | No recorded boards and no power distribution; median output is unknown and assumed modest given the split engine (Inferred) |
| D5 | Interruption Resilience & Route Redundancy | 60 | 12 hand traps, Mulcharmy draws and Barian's searches give several independent answers after one disruption (Inferred) |
| D6 | Resource Economy, Recovery & Grind | 60 | Mulcharmy draws, 17 searcher-text cards and Ryzeal Cross recursion sustain card flow over a long game (Inferred) |
| D7 | End-Board & Interaction Quality | 74 | 12 hand traps plus Ryzeal Detonator, Dominus Spark, Cosmic Cyclone and Number-style negations give layered, durable interaction (Inferred from text) |
| D8 | Going-Second & Board-Breaking Power | 70 | Nibiru, Ghost Ogre, Droll & Lock Bird and Dominus Spark challenge an established board when going second (Inferred from text) |
| D9 | Offensive Pressure & Closing Power | 66 | Several 3000-ATK Xyz boss monsters (C104, Ryzeal Detonator, Divine Arsenal) close games, but no end-board data supports a closing rate (Inferred from stats) |
| D10 | Main Deck Efficiency & Flexibility | 38 | 57 main cards in 25 distinct names, 13 three-copy cards, 4 over-limit copies and only 13.9% exact-name archetype purity point to a bloated, inconsistent main deck (Verified composition) |
| D11 | Extra Deck Efficiency & Coverage | 48 | 15 Xyz monsters across 14 distinct names; core Masquerade and Umbral Xyz are present, but the Ryzeal, Number and Barian's pieces are split across sub-archetypes (Verified composition) |
| D12 | Side Deck Adaptability | 10 | No side deck is registered, so there is no post-side adaptability (Verified) |
| D13 | Matchup Coverage & Format Fit | 50 | No tournament link or dated meta sample exists, so matchup fit is provisional (Provisional) |
| D14 | Pilotability & Error Tolerance | 35 | Many branching decision points across several sub-archetypes, with hand-trap timing and Xyz material choices, make the deck demanding to pilot (Inferred) |
