Final Contextual Deck Power: 30/100 (Confidence: Low)
- Primary strategy: Midrange
- Secondary strategies: Toolbox, Stun
- Format: ocg
Legality
Main 56 / Extra 14 / Side 0 — status: Illegal. 2 violation(s).
Identity & game plan
- Win condition: Union/LIGHT Machine boards: Union monsters equipped and revived via Union Activation, Union Hangar, Unauthorized Reactivation and Fusion/Link/XYZ extension (ABC-Dragon Buster, Cyber Dragon Nova, Tellarknight, Rasterliger), with boss pressure from 3000-ATK monsters; Negate-and-search interaction (Ash Blossom, Nibiru, Infinite Impermanence, Ghost Ogre, Droll) to deny the opponent's line while the Union board develops
- Turn 1 (going first): Search a Union Hangar or Union Activation, then Normal Summon a LIGHT Machine Union monster and equip it with Unauthorized Reactivation or a Union equip effect; Link or Fusion Summon from the Extra Deck once the board has two Machine monsters
- Turn 2 (going second): Hold Ash Blossom / Ghost Ogre / Nibiru / Infinite Impermanence for the opponent's starter, then rebuild the Union board with Union Activation's GY effect and Dominus Purge / Solemn traps as protection
- Recovery: Re-search a Union or Therion card via Union Hangar, Therion Discolosseum or Terraforming; Union Activation and Unauthorized Reactivation recur from the GY
- After siding: Not evaluable: the deck has no side deck (side_count 0), so there is no post-side plan
Why it scores here
The deck is scored as a system on its structure only, because it is Illegal: Ash Blossom & Joyous Spring is run three times against a Semi-Limited limit of two, so the evaluation is capped and labelled theoretical. Its searchers (14 cards, about 78% chance of at least one in a 5-card opening hand) and its Union/LIGHT Machine engine give a plausible T1-T2 plan, but the Union monsters need an equip target or an Extra Deck summon, which keeps brick risk high. Interaction is the strongest part of the list: 14 hand traps and 15 negation-text cards, with an 84% chance of at least one going second. There are no recorded boards, so combo ceiling and median are text-only inferences, and popularity or meta share did not earn points. The cards' individual power scores were not averaged into the deck score.
Dimension scores
| # | Dimension | Score | Evidence |
|---|---|---|---|
| D1 | Engine Accessibility & Consistency | 55 | Searcher text in 14 main-deck cards, P(at least one in 5-card hand) = 0.78; Union starters need a second piece, so consistency is moderate (Inferred) |
| D2 | Opening-Hand Quality & Brick Management | 45 | Eighteen Spells and thirteen Traps in 56 cards, with Union monsters dead without an equip target; brick and conflicting-piece risk is moderate (Inferred) |
| D3 | Combo Conversion & Ceiling | 45 | No boards recorded (total_combos 0); ceiling from card text only: Union equip chains into Fusion/Link/XYZ boss monsters (Inferred) |
| D4 | Combo Floor & Median Output | 40 | No recorded median output; the floor depends on whether the Union engine connects without a hand trap or search (Inferred) |
| D5 | Interruption Resilience & Route Redundancy | 50 | Multiple negation and hand-trap lines and GY recursion (Union Activation, Unauthorized Reactivation) give some route redundancy (Inferred) |
| D6 | Resource Economy, Recovery & Grind | 45 | Recursion from GY via Union Activation and Reactivation, plus Union Hangar and Therion Discolosseum searches; card-advantage data absent (Inferred) |
| D7 | End-Board & Interaction Quality | 60 | 14 hand traps, Solemn Judgment, Solemn Warning, Dominus Purge, Nibiru, Dark Ruler No More and Lightning Storm give layered, broad interaction (Inferred semantic reading, with flag evidence) |
| D8 | Going-Second & Board-Breaking Power | 50 | Going-second hand trap probability 0.84; Barbaros and Lightning Storm are board breakers, but there are no going-second board records (Inferred) |
| D9 | Offensive Pressure & Closing Power | 50 | Boss monsters at 3000 ATK (Beast King Barbaros, ABC-Dragon Buster, XYZ-Hyper Dragon Cannon) and Union equip pressure; no end-board records (Inferred) |
| D10 | Main Deck Efficiency & Flexibility | 40 | 56 Main Deck cards with 35 distinct; archetype purity 0% exact-name, spread across ABC, A-to-Z, Solemn, Dominus and Machina; high tech count (24) and dense copy counts (Inferred) |
| D11 | Extra Deck Efficiency & Coverage | 60 | Extra Deck of 14 cards with Fusion 6, Link 4, XYZ 3 and Synchro 1, all used across the engine; no mandatory-slot data (Verified breakdown, Inferred use) |
| D12 | Side Deck Adaptability | 5 | No side deck (side_count 0), so no post-side adaptability can be assessed (Verified) |
| D13 | Matchup Coverage & Format Fit | 40 | No tournament link or dated meta sample; archetype meta share unavailable, so this is Provisional |
| D14 | Pilotability & Error Tolerance | 40 | Multi-step Union equip chains with Extra Deck summons, plus several negation timing decisions (Inferred) |
