Umbral Horror — Deck Power Evaluation
Final Contextual Deck Power: 16/100 (±4 · Confidence: Low)

Legality
Main 40 / Extra 15 / Side 0 — status under the rules at evaluation time: Illegal. 1 violation(s).
Identity & game plan
- Win condition: Summon Rank 4/5 XYZ bosses (Number C104 etc.); Hand trap disruption
- Turn 1 (going first): Set hand traps, establish XYZ board with negation
- Turn 2 (going second): Use board breakers / hand traps to disrupt and summon XYZ
- Recovery: Limited recursion via traps/spells
- After siding: No side deck (illegal list)
Why it scores here
This deck is illegal in OCG due to a Forbidden copy of Maxx "C", so its evaluation is theoretical and capped low. Even ignoring legality, the list is a loosely connected pile of Rank-4 XYZ enablers, hand traps, and unrelated splash cards with only 12% of the archetype's core cards present, yielding poor engine cohesion and no recorded combos. Consistency is modest via three-of searchers but brick risk is high from many singleton off-theme cards, and the extra deck lacks redundancy. The score reflects system weakness and illegality, not any averaged card power, and popularity stats do not add points.
Dimension scores
| # | Dimension | Score | Evidence |
|---|---|---|---|
| D1 | Engine Accessibility & Consistency | 30 | Hypergeometric P(≥1 searcher in 5) ≈0.78 but archetype core only 12% present; engine fragmented (Inferred) |
| D2 | Opening-Hand Quality & Brick Management | 35 | Copy histogram shows 9 singles; many off-theme cards increase brick risk (Inferred) |
| D3 | Combo Conversion & Ceiling | 30 | No parseable combos; text suggests XYZ summoning but ceiling unclear (Inferred) |
| D4 | Combo Floor & Median Output | 25 | No median combo data; expected low median output due to missing core (Inferred) |
| D5 | Interruption Resilience & Route Redundancy | 20 | Starter diversity low; only few redundant searchers; fragile to disruption (Inferred) |
| D6 | Resource Economy, Recovery & Grind | 25 | Resource economy weak; little recursion beyond traps (Inferred) |
| D7 | End-Board & Interaction Quality | 30 | Extra deck provides negation (Number 104 etc.) but layering poor (Inferred) |
| D8 | Going-Second & Board-Breaking Power | 25 | Going-second hand trap density P≈0.71 but few board breakers (Inferred) |
| D9 | Offensive Pressure & Closing Power | 30 | Big XYZ ATK up to 3100 but inconsistent closing (Inferred) |
| D10 | Main Deck Efficiency & Flexibility | 30 | Main deck 96% off-archetype purity; inefficient (Inferred) |
| D11 | Extra Deck Efficiency & Coverage | 40 | Extra deck all 15 XYZ, some coverage but many singles (Observed) |
| D12 | Side Deck Adaptability | 0 | Side deck absent (0 cards) (Verified) |
| D13 | Matchup Coverage & Format Fit | 20 | No tournament context; matchup fit provisional (Provisional) |
| D14 | Pilotability & Error Tolerance | 30 | Combo steps unclear; pilot must juggle many engines (Inferred) |
How the score was computed
Strategy profile: Toolbox. Structural ≈ 27, Going First ≈ 25, Going Second ≈ 22, Meta = provisional, Tournament Reliability ≈ 20. Modifiers: Illegal deck (Forbidden card) (-10). Final formula: 0.80*Structural + 0.20*TournamentReliability + ContextModifiers (Meta provisional)
Probability & combo summary
- Opening a starter: P(≥1) ≈ 0.78 · 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
- Some hand trap density
- Extra deck provides negation options
Weaknesses
- Illegal due to Forbidden Maxx C
- Extremely low archetype core coherence
- No side deck
- No recorded combos
Critical choke points
- Maxx C illegal
- Lack of core engine cards
Recommended changes
| Priority | Remove | Add | Reason |
|---|---|---|---|
| 1 | Maxx "C" | Legal hand trap e.g. Effect Veiler | Remove forbidden card to make deck legal |
Evidence & confidence
- Verified: Legality status Illegal; Extra deck 15 XYZ monsters; Side count 0
- Observed: No combos parsed; Usage stats show core present 12%
- Inferred: Consistency estimates from hypergeometric; Brick risk from singles
- Provisional: Matchup fit; Meta Power
- Data gaps: no combos supplied — combo floor/median/ceiling is text-only inference no tournament link — archetype meta-share and per-pilot match record absent no win-rate telemetry exists in YGOVN (going-first/second, matchup, game-level, brick/starter/OTK rates) — those signals are Inferred or Unknown Meta Power is Provisional unless a dated metagame sample is supplied
