Main 40 / Extra 15 / Side 0 — status: Legal.
Identity & game plan
- Win condition: Union monsters equipped and Fusion/XYZ bosses (ABC-Dragon Buster 3000 ATK, A-to-Z-Dragon Buster Cannon 4000 ATK, XYZ-Dragon Cannon 2800 ATK) stay on the field behind hand traps; Union Driver and Union Hangar chains that recycle equip-based pressure from the GY and banish zone
- Turn 1 (going first): Union Activation or Union Hangar to search a Union monster, equip it to a Level 4 Machine, then build toward an ABC/XYZ fusion using banished Union monsters (Inferred from card text)
- Turn 2 (going second): Hold Ash Blossom, Effect Veiler, Droll and Infinite Impermanence for the opponent's first plays, then use Union follow-ups and Mulcharmy draws to rebuild (Inferred)
- Recovery: Union Scramble and A-to-Z Energy Load recover banished Union monsters; Mulcharmy draw effects replace cards after an interruption (Inferred)
- After siding: Not evaluable: the deck runs 0 side cards, so there is no post-side plan
Why it scores here
The deck reliably opens a Union engine: Union Activation and Union Hangar search a Union monster, and the 22 archetype-core copies give about a 0.99 chance of at least one in an opening five-card hand (Inferred). Its power comes from the system rather than from the individual cards. Eight hand traps plus Mulcharmy draw effects give it a real way to survive one interruption, and the Extra Deck bosses (ABC-Dragon Buster, A-to-Z-Dragon Buster Cannon, XYZ-Dragon Cannon) supply closing power. The score is held back by the absence of any recorded combo boards, a zero-card side deck, and several Extra Deck slots with no clear material route from the main-deck engine. Archetype popularity (the ABC guide and 100% core inclusion) confirms the list is real but earned no points. The score was not produced by averaging card scores.
Dimension scores
| # | Dimension | Score | Evidence |
|---|---|---|---|
| D1 | Engine Accessibility & Consistency | 62 | P(at least one Union Activation in opening 5) ≈ 0.34; P(at least one searcher-text card in opening 5) ≈ 0.69; the 22 archetype-core copies give 0.99 (Inferred) |
| D2 | Opening-Hand Quality & Brick Management | 58 | Union monsters are often dead without a live starter, and the Mulcharmy pair is a conditional brick on a non-empty board; eight hand traps add 1-2 copy redundancy (Inferred) |
| D3 | Combo Conversion & Ceiling | 62 | No parseable combo boards; the ceiling is read from text, e.g. ABC-Dragon Buster's banish-and-destroy effects and the fusion material chain (Inferred from text only) |
| D4 | Combo Floor & Median Output | 50 | No recorded median or power distribution exists, so the floor is neutral by default and capped at 50 (Inferred) |
| D5 | Interruption Resilience & Route Redundancy | 68 | Eight hand traps (Ash x2, Droll x2, Effect Veiler x2, Infinite Impermanence, Maxx C) plus Union Scramble recursion give multiple independent answers (Inferred from card text) |
| D6 | Resource Economy, Recovery & Grind | 66 | Mulcharmy draws, Union Hangar and Union Driver search, Maxx C draw and Union Scramble recursion (Inferred from card text; no resource telemetry) |
| D7 | End-Board & Interaction Quality | 64 | Negation text across Ash, Effect Veiler, Infinite Impermanence and the A-to-Z Dragon Buster Cannon negate effect; P(hand trap in opening 6 going second) ≈ 0.76 (Inferred) |
| D8 | Going-Second & Board-Breaking Power | 62 | Going-second hand-trap probability is strong, and ABC-Dragon Buster and XYZ-Dragon Cannon can destroy board cards; no going-second split data exists (Inferred) |
| D9 | Offensive Pressure & Closing Power | 70 | Bosses at 4000, 3000, 3000 and 2800 ATK in the Extra Deck; closing depends on keeping a Union monster alive (Verified stats, Inferred conversion) |
| D10 | Main Deck Efficiency & Flexibility | 60 | 40-card main at the minimum legal size; 25 distinct cards with 13 playsets and one triple; exact-name ABC purity is 30.9%, but Union is a mechanic-based engine (Verified composition, Inferred coherence) |
| D11 | Extra Deck Efficiency & Coverage | 55 | 15 Extra Deck cards: 9 Fusion, 4 Link, 2 XYZ; at least six (Garura, Mudragon, Knightmare Phoenix, Underworld Goddess, I:P Masquerena, S:P Little Knight) lack a clear material route in the main deck (Verified breakdown, Inferred routes) |
| D12 | Side Deck Adaptability | 30 | Zero side-deck cards, so no post-side adaptability; scored low as Provisional with no post-side performance data |
| D13 | Matchup Coverage & Format Fit | 50 | Archetype tournament share is unavailable and no dated meta sample exists; scored neutral and Provisional |
| D14 | Pilotability & Error Tolerance | 45 | Multi-step equip, banish-for-fusion and conditional Mulcharmy interactions raise the decision load (Inferred from text) |
How the score was computed
Strategy profile: Midrange. Structural ≈ 59.9, Going First ≈ 63, Going Second ≈ 64, Meta = provisional, Tournament Reliability ≈ 58. Modifiers: Engine conflict (-2); Unverified Extra Deck routes (-2); Banlist exposure (0). Final formula: 0.80*Structural + 0.20*TournamentReliability + ContextModifiers (Meta provisional, no dated metagame sample)
Probability & combo summary
- Opening a starter: P(≥1) ≈ 0.69 · 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
- Eight hand traps and multiple negation effects give layered interaction
- Union redundancy: 22 archetype-core copies and 4 search routes
- Strong Fusion/XYZ bosses in the Extra Deck with high ATK and removal text
Weaknesses
- No combo boards recorded, so the ceiling and median are text-inferred
- Zero side deck cards
- Several Extra Deck slots have no clear material route from the main deck
- Mulcharmy's control-no-cards condition conflicts with the Union board
Critical choke points
- A live Union monster on the field is the single point that every line needs
- Mulcharmy's draw effect is unavailable whenever the Union board is up
Recommended changes
| Priority | Remove | Add | Reason |
|---|---|---|---|
| 1 | Garura, Wings of Resonant Life | A side deck of 5-8 cards (e.g. extra hand traps or a Union Activation copy) | A zero-card side deck gives D12 no post-side plan, and Garura has no clear material route (Inferred) |
| 2 | Mudragon of the Swamp | A second Union Hangar or an extra searcher-text card | Mudragon needs two WATER monsters of different Types, and the main deck supplies only Mulcharmy Purulia (Inferred) |
Evidence & confidence
- Verified: Legal size: 40 Main, 15 Extra, 0 Side; Copy limits: Maxx C 1/1, Droll 2/2, Super Polymerization 2/2; Extra Deck breakdown: 9 Fusion, 4 Link, 2 XYZ; Boss ATK values: 4000, 3000, 3000, 2800
- Observed: Usage statistics show 100% inclusion for the archetype-core cards that are present
- Inferred: Starter and hand-trap probabilities from hypergeometric estimates; Going-first and going-second plans from card text; Engine conflict between Mulcharmy and Union; Extra Deck material routes
- Provisional: Meta power (null); Matchup fit (D13); Post-side plan (D12)
- Data gaps: No combos supplied: combo floor, median and ceiling are text-only inference No tournament link: archetype meta share and pilot match record are absent No win-rate telemetry exists for this deck usage_statistics.missing_core lists ABC-Dragon Buster, XYZ-Dragon Cannon, Union Controller and others as not in the deck, but the cards array lists them in the Extra Deck with copies; the core_present_pct of 56 is therefore unreliable and was not used Meta power is Provisional without a dated metagame sample Side deck is empty, so post-side performance cannot be assessed
