Deck — Deck Power Evaluation
Final Contextual Deck Power: 25/100 (Confidence: Low)
- Primary strategy: Midrange
- Secondary strategies: Stun, Toolbox
- Format: ocg
Legality
Main 55 / Extra 15 / Side 0 — status under the rules at evaluation time: Illegal. 2 violation(s).
Identity & game plan
- Win condition: Xyz pressure through Masquerade / Constellar Xyz monsters (2700-2900 ATK boss bodies) built off a Level 4 starter chain; Hand-trap-protected Xyz follow-up backed by Barian's Seventh Untopia and Number recursion
- Turn 1 (going first): Open a Level 4 starter (Mulcharmy Fuwalos, Tellarknight Cygnian/Lyran, Constellar Castor), search a Constellar/Tellarknight monster, and Xyz into a Masquerade or Constellar boss while holding Ash Blossom for the opponent's first activation
- Turn 2 (going second): Use Ash Blossom and Ghost Ogre / Ghost Belle as hand traps on the opponent's starter, then rebuild through Thousand Umbral Horror / V Umbral Horror searches into a boss
- Recovery: Recover via searchers (Constellar Caduceus, V Umbral Horror, Seventh Ascension) and Xyz material recycling; not verified by any recorded board
- After siding: Not evaluable: the deck has no Side Deck, so there is no post-side plan
Why it scores here
The score reflects the deck as a system, not an average of its cards. Thirteen copies of the archetype core and 20 searcher-text cards give a reasonably high chance of a live Level 4 starter by turn 1 (P(at least one core card in a 5-card opening) ≈ 0.76, Inferred). Seven hand traps and about 11 negation effects provide layered interaction, and the Masquerade and Constellar Xyz bodies at 2700 to 2900 ATK supply closing pressure. However, the list has only 6 exact-name archetype copies (8.6% purity) across several sub-archetypes, the Side Deck is empty, and no recorded boards exist, so median output and combo conversion remain unmeasured. The deck is Illegal in OCG: three copies of Seventh Tachyon (limit 1) and three copies of Ash Blossom & Joyous Spring (limit 2) exceed the banlist, so the score is capped and is theoretical or structural only. Popularity of the archetype did not earn points.
Dimension scores
| # | Dimension | Score | Evidence |
|---|---|---|---|
| D1 | Engine Accessibility & Consistency | 70 | P(≥1 core card in 5-card hand) ≈ 0.76 across 13 archetype copies; 20 searcher-text cards ≈ 0.91 (Inferred) |
| D2 | Opening-Hand Quality & Brick Management | 50 | Many off-archetype and single-copy support cards and no brick estimate beyond composition (Inferred) |
| D3 | Combo Conversion & Ceiling | 50 | No recorded boards; ceiling inferred from card text only, e.g. Xyz bosses at 2700-2900 ATK (Inferred) |
| D4 | Combo Floor & Median Output | 45 | No combos_evidence, so the median is unknown and kept low by default (Inferred) |
| D5 | Interruption Resilience & Route Redundancy | 60 | Seven hand traps and two searchers give at least two independent response routes (Inferred) |
| D6 | Resource Economy, Recovery & Grind | 55 | Recursion and searchers in text (Seventh Ascension, V Umbral Horror, Constellar Caduceus); no resource signature available (Inferred) |
| D7 | End-Board & Interaction Quality | 68 | Ash Blossom and Ghost Ogre/Belle plus about 11 negation effects and 22 removal-text cards (Inferred semantic read; banlist-limited copies) |
| D8 | Going-Second & Board-Breaking Power | 60 | Going-second hand-trap coverage: P(≥1 hand trap in 6-card hand) ≈ 0.58 (Inferred) |
| D9 | Offensive Pressure & Closing Power | 62 | Xyz bosses at 2700 to 2900 ATK in Extra Deck (Verified stat, Inferred closing use) |
| D10 | Main Deck Efficiency & Flexibility | 45 | 55 Main Deck cards inside the 40-60 range, but purity is 8.6% across 28 distinct cards (Inferred) |
| D11 | Extra Deck Efficiency & Coverage | 55 | 15 Xyz Extra Deck cards, all Xyz; flexible within the Xyz pool but heavy on single copies (Inferred) |
| D12 | Side Deck Adaptability | 25 | Side Deck is empty (Verified, 0 side cards); no post-side plan exists |
| D13 | Matchup Coverage & Format Fit | 40 | No tournament link and no dated meta sample; Provisional |
| D14 | Pilotability & Error Tolerance | 40 | Multi-step Xyz chains with many named-card interactions; error tolerance estimated (Inferred) |
