Final Contextual Deck Power: 32/100 (Confidence: Low)
- Primary strategy: Midrange
- Secondary strategies: Toolbox, Control
- Format: ocg
Legality
Main 57 / Extra 15 / Side 0 — status: Illegal. 6 violation(s).
Identity & game plan
- Win condition: Extra Deck boss monsters from the LIGHT Machine Union/ABC/A-to-Z line (ABC-Dragon Buster, XYZ-Hyper Dragon Cannon) and Fiendsmith Fusions (Fiendsmith's Desirae, Lacrima), converted through board-breaking negations and removal (Inferred); Therion "King" Regulus as a 2800-ATK attacker that negates on the opponent's activations, supported by Photon Strike Bounzer and Ancient Fairy Dragon (Inferred)
- Turn 1 (going first): Open with a searcher (Union Hangar, Union Activation, Fiendsmith Engraver or Tract) into a Union or ABC Machine line, keeping Ash Blossom and Infinite Impermanence up for the opponent's first activation (Inferred)
- Turn 2 (going second): Use the hand traps (Ash, Droll, Evenly Matched, Solemn Warning/Judgment, Impermanence) to slow the opponent's first board, then rebuild through the searchers and Extra Deck Fusion or Link summons (Inferred)
- Recovery: Recover through Fiendsmith's Lacrima and Requiem recursion from the GY, Union equip-revival from the GY, and the Therion Discolosseum search (Inferred)
- After siding: Not evaluable: the deck runs an empty Side Deck, so there is no post-side plan (verified from the evidence; no performance data)
Why it scores here
The deck is Illegal in OCG: six copies across three Forbidden or Limited cards and three over-limit Semi-Limited or Limited cards, so the score is capped and the result is structural-only. Structurally, it reliably finds a searcher (P(at least one searcher in an opening hand of 5) ≈ 0.84, Inferred), and its hand-trap and negation density (about 10 hand traps and 15 negation-text cards) gives it real end-board interaction. Its engine is split across at least four sub-archetypes (ABC, A-to-Z, Fiendsmith, and Union Machine, with Therion only through Regulus), so exact archetype purity is 0% and engine cohesion is weak. There are no recorded boards, no tournament or win-rate data, and an empty Side Deck, so floor, median and ceiling are all unmeasured. The score comes from consistency and interaction on the system, not from the archetype's popularity and not from averaging the card scores.
Dimension scores
| # | Dimension | Score | Evidence |
|---|---|---|---|
| D1 | Engine Accessibility & Consistency | 42 | P(≥1 Ash Blossom in 5 cards) ≈ 0.24 and P(≥1 searcher in 5) ≈ 0.84 across four competing engines (Inferred) |
| D2 | Opening-Hand Quality & Brick Management | 40 | About 10 hand traps and 30 level-0 spells/traps dilute the opening hand, and the hand-trap group reaches P≈0.70 going second (Inferred) |
| D3 | Combo Conversion & Ceiling | 35 | No parseable combos; conversion is inferred from card text only (Inferred) |
| D4 | Combo Floor & Median Output | 35 | No combo boards, so median output cannot be measured (Inferred, Provisional) |
| D5 | Interruption Resilience & Route Redundancy | 50 | Several independent recursion and search routes (Lacrima, Requiem, Union revival, Discolosseum) give some redundancy (Inferred) |
| D6 | Resource Economy, Recovery & Grind | 45 | Recursion and search text is present, but no resource signature was supplied (Inferred) |
| D7 | End-Board & Interaction Quality | 60 | Dense negation and removal: Ash, Impermanence, Solemn Warning/Judgment, Droll, Duster, Regulus, Lightning Storm (Inferred from text, with verified card text) |
| D8 | Going-Second & Board-Breaking Power | 50 | Lightning Storm, Harpie's Feather Duster and Dragon Buster give board-breaking options, but without going-second split data (Inferred) |
| D9 | Offensive Pressure & Closing Power | 55 | Extra Deck bosses at 2800–3000 ATK (Dragon Buster, Hyper Dragon Cannon, Desirae) give closing power (verified stats, Inferred use) |
| D10 | Main Deck Efficiency & Flexibility | 35 | 57 Main Deck cards from 37 distinct, with 30 level-0 cards and 17 Spells, is low on compactness (verified counts) |
| D11 | Extra Deck Efficiency & Coverage | 50 | 15 Extra Deck slots across 14 distinct cards, with mandatory Union, ABC and Fiendsmith material demands (verified counts, Inferred) |
| D12 | Side Deck Adaptability | 20 | No Side Deck at all, so no adaptability is available (verified; Provisional) |
| D13 | Matchup Coverage & Format Fit | 40 | No tournament or meta data; format fit is Provisional (Provisional) |
| D14 | Pilotability & Error Tolerance | 30 | Four engines and many decision points raise the error rate for a repeatable pilot (Inferred) |
