Legality
Main 56 / Extra 15 / Side 0 — status under the rules at evaluation time: Illegal. 3 violation(s).
Identity & game plan
- Win condition: Union monster attacks and boards, with ABC and Union Machine bodies (B-Buster Drake, A-Assault Core, C-Crush Wyvern, ABC-Dragon Buster) converting the engine into pressure; Fusion and link finishers from the Extra Deck (Union Controller, ABC-Dragon Buster, XYZ-Hyper Dragon Cannon, Fiendsmith's Desirae) once the board is established
- Turn 1 (going first): Open with Union Hangar or Union Activation to search a LIGHT Machine Union monster, then equip through Unauthorized Reactivation or Ghost Belle / Ash Blossom to protect the first body and build toward a Fusion or Link Summon
- Turn 2 (going second): Hold hand traps (Ash Blossom, Ghost Belle, Effect Veiler, Droll & Lock Bird, Maxx C) to answer the opponent's first Summon, then rebuild a Union board from the Deck
- Recovery: Recover through the graveyard: Ghost Belle and Ash Blossom retrieve cards, Union Activation and Therion Discolosseum refill the hand, and Union Hangar searches again
- After siding: No side deck is registered (0 cards), so the deck has no post-side plan; the list cannot adapt between games
Why it scores here
This list is Illegal in Master Duel: Droll & Lock Bird is run three times against a limit of two, Maxx C twice against one, and Called by the Grave (Forbidden) twice, so the score is capped and the evaluation is structural-only. The Union core is dense (about 28 archetype-core copies), which makes a starter likely in the opening hand, and 17 hand traps plus 18 negation-text cards give the deck real interaction on the going-second turn. The Extra Deck and main deck mix Union, Fiendsmith, Therion, Charmer, Elemental HERO and A-to-Z pieces (only about 13% of main deck copies match the exact ABC name), so engine coherence and brick risk pull the score down. No recorded boards, tournament results or side-deck plan exist, so the floor, median and matchup scores are inferred from card text, not measured; the archetype's popularity earned no points, and card scores were not averaged into the deck score.
Dimension scores
| # | Dimension | Score | Evidence |
|---|---|---|---|
| D1 | Engine Accessibility & Consistency | 62 | Core Union starters run at 3 copies each, and P(at least one archetype-core card in a 5-card opening hand) is about 0.97 (Inferred) |
| D2 | Opening-Hand Quality & Brick Management | 50 | Many hands will hold hand traps or Union pieces with no board to use them on; 17 hand traps and multiple non-engine singles raise the dead-card rate (Inferred) |
| D3 | Combo Conversion & Ceiling | 45 | No recorded boards exist; the ceiling is read from card text, with Union Controller and ABC-Dragon Buster as Fusion finishers and the Union equip chain as the engine (Inferred) |
| D4 | Combo Floor & Median Output | 35 | No recorded boards exist, so the median output is unmeasured and only estimated from the deck's starters and the Extra Deck's breadth (Inferred) |
| D5 | Interruption Resilience & Route Redundancy | 60 | Ghost Belle, Ash Blossom and Effect Veiler keep the engine going through a single interruption, and Union Hangar and Union Activation offer independent restarts (Inferred) |
| D6 | Resource Economy, Recovery & Grind | 55 | Union Hangar and Union Activation search, and Ghost Belle recurs from the GY, so the deck regenerates resources well (Inferred) |
| D7 | End-Board & Interaction Quality | 60 | 17 hand traps and 18 negation-text cards give layered interaction, but a Forbidden card is in the list (Inferred) |
| D8 | Going-Second & Board-Breaking Power | 65 | Hand traps ready to answer the first Summon give the deck strong going-second interaction, with ABC-Dragon Buster as a board-breaking finisher (Inferred) |
| D9 | Offensive Pressure & Closing Power | 60 | Closing bodies reach 2800-3000 ATK, including ABC-Dragon Buster and XYZ-Hyper Dragon Cannon, but there is no evidence of how often they connect (Inferred) |
| D10 | Main Deck Efficiency & Flexibility | 45 | 56 main deck cards with 28 distinct, but the list spans six or more sub-archetypes and carries 22 level-0 spells and traps, so it is less compact than a single-theme build (Inferred) |
| D11 | Extra Deck Efficiency & Coverage | 42 | Fusion and Link pieces from Union, Fiendsmith, Knightmare, Charmer and Gadget share the 15 slots, so the Extra Deck is spread thin (Inferred) |
| D12 | Side Deck Adaptability | 12 | Side deck is 0 cards, so no post-side adjustment exists (Verified, legality data) |
| D13 | Matchup Coverage & Format Fit | 40 | No tournament share or matchup record exists, so format fit is Provisional and only archetype context applies (Provisional) |
| D14 | Pilotability & Error Tolerance | 35 | Multi-step Union equip chains, several archetype branches and many hand-trap timing decisions make the deck hard to pilot consistently (Inferred) |
How the score was computed
Strategy profile: Midrange. Structural ≈ 51, Going First ≈ 48, Going Second ≈ 56, Meta = provisional, Tournament Reliability ≈ 42. Modifiers: banlist exposure (-6); engine conflicts (-3). Final formula: 0.80*Structural + 0.20*TournamentReliability + ContextModifiers = 40 theoretical, capped at 30 because the list is Illegal (Meta provisional)
Probability & combo summary
- Opening a starter: P(≥1) ≈ 0.97 · 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
- Dense Union core with 3-copy engine pieces and two recovery-friendly searchers
- 17 hand traps and 18 negation-text cards give layered interaction on the going-second turn
- Closing bodies reach 2800-3000 ATK, and Fusion finishers can clear the board
Weaknesses
- Illegal copy counts for three cards, so the list cannot be played as built
- Multi-archetype build (Fiendsmith, Therion, Charmer, Elemental HERO, A-to-Z) dilutes the engine
- No side deck, so the deck cannot adapt between games
Critical choke points
- The Union equip chain depends on a single LIGHT Machine Union starter on turn 1
- Hand traps and negations need the right card in hand at the right moment; a hand full of them is dead without a board
Recommended changes
| Priority | Remove | Add | Reason |
|---|---|---|---|
| 1 | Called by the Grave (2 copies, Forbidden) | A legal in-format card that fills the same role, such as a Union-compatible extender or Limited-legal removal already in the list | A Forbidden card makes the deck illegal; this is the first fix needed before any other evaluation applies |
| 2 | One copy of Droll & Lock Bird and one copy of Maxx C | Legal-count replacements from the same engine role (one hand trap or one draw card) | Brings copy counts within the Semi-Limited and Limited limits and keeps the interaction count close to the current level |
| 3 | Off-archetype Extra Deck cards that do not fit the Union core (for example one Link or Fusion from a different theme) | One more Union-compatible Fusion or Link finisher, or a side deck of 15 cards | Reduces engine conflict and gives the deck a post-side plan, which it currently lacks |
Evidence & confidence
- Verified: Illegal copy counts for Droll & Lock Bird, Maxx C and Called by the Grave; Main Deck size 56 and Extra Deck size 15 are within Master Duel limits; Side deck is 0 cards; Archetype purity: 12.7% exact-name match
- Observed: Archetype core presence: 12 of 25 standard core cards are in the list
- Inferred: Opening-hand starter estimate about 0.97; Interaction and resilience scores from card text; Going-first and going-second estimates
- Provisional: Meta power and matchup fit (no dated meta sample); Tournament reliability
- Data gaps: No recorded combos, so floor, median and ceiling are text-only inference No tournament link, so archetype meta-share and per-pilot match record are absent No win-rate telemetry exists for going-first, going-second, matchup, brick or OTK rates No side deck, so post-side performance is untested Meta power is provisional until a dated metagame sample is supplied
