Legality
Main 55 / Extra 15 / Side 0 — status: Illegal. 1 violation(s).
Identity & game plan
- Win condition: Xyz pressure from Level 4 fodder into 2500-ATK Utopia/Number bosses, with Evilswarm Ophion and Evolzar Laggia-type negation boards (theoretical; the list is illegal and no boards were recorded); Hand-trap and Trap-based interaction (Infinite Impermanence, Light-Imprisoning Mirror, Non-Fusion Area, Macro Cosmos) that stalls the opponent's board until the Xyz line lands
- Turn 1 (going first): Normal Summon Evilswarm Castor or Heliotrope, use Primite or Lswarm searchers to find Xyz fodder, and hold Infinite Impermanence or Mirror for the opponent's first activation
- Turn 2 (going second): Use hand traps (6 copies, about 52 percent to hold one in a 6-card hand) to break the opponent's first Summon, then transition to an Xyz with the remaining Level 4 monsters
- Recovery: Searchers (Primite Lordly Lode, Primite Dragon Ether Beryl, Ophion) and Xyz detach effects rebuild the board, but there are only four searcher-text cards
- After siding: Not applicable: the export contains no Side Deck, so there is no post-side plan
Why it scores here
This list is not legal in OCG: it runs three copies of Dimension Shifter, which is Forbidden, so the score is a structural-only read capped at 20 and is not a normal Final Contextual score. The structure is a loose Toolbox: 70 of 85 cards are off the exact Steelswarm (Inverz) name, with only 23 distinct Main Deck cards spread across Lswarm, Primite, Kaiju, Mulcharmy and Utopia pieces, so consistency and engine cohesion are weak. Interaction is the strongest part of the system (19 negation-text and 16 removal-text cards, six hand traps, and floodgates), which lifts the end-board and going-second dimensions. There are no recorded boards, no guides, no tournament link and no Side Deck, so floor, median and ceiling are text-only inference. The score comes from the system's consistency, interaction density and missing post-side plan, not from averaging the individual card scores and not from the archetype's usage statistics.
Dimension scores
| # | Dimension | Score | Evidence |
|---|---|---|---|
| D1 | Engine Accessibility & Consistency | 40 | P(at least one 3-copy starter in a 5-card opening hand) is about 0.25 per copy group, but the archetype core group has about 0.99 coverage across 34 Level 4 and archetype cards; coherence is low with 70 off-archetype copies (Inferred) |
| D2 | Opening-Hand Quality & Brick Management | 35 | Nineteen Trap Cards and nine tech cards with 13 Dark Hole-style or hand-dependent pieces in a 55-card main give a high risk of dead or conflicting hands (Inferred) |
| D3 | Combo Conversion & Ceiling | 40 | No recorded boards; the Level 4 fodder into Utopia and Number Xyz routes is plausible from card text but the ceiling is unverified (Inferred) |
| D4 | Combo Floor & Median Output | 30 | No combo data, so the median output is unknown and is set low for the lack of a second independent line in the text (Inferred) |
| D5 | Interruption Resilience & Route Redundancy | 45 | Several interaction and summon routes (Rescue Rabbit, Herald, Primite Drillbeam, Macro Cosmos) give partial redundancy, but no recursion beyond four searcher-text cards (Inferred) |
| D6 | Resource Economy, Recovery & Grind | 42 | Four searcher-text cards and detach effects on Ophion and Bahamut-type Xyz give limited recovery; there is no proven grind data (Inferred) |
| D7 | End-Board & Interaction Quality | 62 | Interaction density is high by text (19 negation text, 16 removal text, six hand traps, floodgates) though much of it is situational and reliant on Trap timing (Inferred) |
| D8 | Going-Second & Board-Breaking Power | 50 | Six hand traps give about 52 percent to hold one in a 6-card hand going second, but Dimension Shifter, the best of them, is illegal (Inferred) |
| D9 | Offensive Pressure & Closing Power | 55 | Xyz bosses at 2500 ATK exist in the Extra Deck, but the deck has no recorded end-board or piercing data (Inferred) |
| D10 | Main Deck Efficiency & Flexibility | 30 | Fifty-five cards with 23 distinct names, three copies of 13 cards, and only 0 exact archetype purity lower compactness (Verified structure, Inferred consequence) |
| D11 | Extra Deck Efficiency & Coverage | 40 | Fifteen Xyz across 14 distinct names with mixed Lswarm, Utopia, Number and Gagaga bosses is spread across too many routes (Verified count, Inferred) |
| D12 | Side Deck Adaptability | 5 | The export contains no Side Deck (0 cards), so there is no adaptability (Verified) |
| D13 | Matchup Coverage & Format Fit | 40 | No dated meta sample and no tournament link; archetype usage stats are available but are not meta share (Provisional) |
| D14 | Pilotability & Error Tolerance | 35 | Multiple Xyz lines, several traps that must be set before use, and negation timing make the deck demanding to pilot (Inferred) |
How the score was computed
Strategy profile: Toolbox. Structural ≈ 41, Going First ≈ 38, Going Second ≈ 44, Meta = provisional, Tournament Reliability ≈ 35. Modifiers: banlist exposure (-12). Final formula: Illegal-list cap. Unclamped: 0.80*41 + 0.20*35 - 12 (banlist exposure) = 28; capped to 20 for an Illegal list, theoretical/structural-only. Meta Power provisional (null).
Probability & combo summary
- Opening a starter: P(≥1) ≈ 0.25 · 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 interaction suite: negation and removal text on 35 cards, six hand traps and floodgates
- Multiple Level 4 Xyz fodder options (Castor, Heliotrope, Purulia, Rescue Rabbit, Primite Beryl)
- Going-second hand-trap coverage of about 52 percent in a 6-card hand
Weaknesses
- Illegal in OCG: Dimension Shifter at 3 copies (Forbidden)
- Low archetype coherence: 0 percent exact-name purity, with 70 off-archetype copies
- No Side Deck, so no post-side adaptation
- Many traps and situational negations make the lines hard to execute consistently
Critical choke points
- Dimension Shifter is a removable but illegal card; any legal rebuild must replace all 3 copies
- Xyz lines depend on Level 4 fodder appearing in the opening hand; no recorded boards confirm it
Recommended changes
| Priority | Remove | Add | Reason |
|---|---|---|---|
| 1 | Dimension Shifter (3 copies) | A legal hand trap or Trap card for the same Level 4 interaction role, such as a legal hand trap from the Lswarm or Utopia pool | The list cannot be legally played in OCG as built |
| 2 | Off-archetype trap or tech slots with no Xyz or Lswarm role | Additional Level 4 Steelswarm or Lswarm monsters for consistent Xyz fodder | Coherence and brick reduction (Inferred) |
| 3 | One or more single-copy Extra Deck Xyz that have no reachable Level 4 fodder | Xyz that the main deck can actually summon | Extra Deck coverage is wide but poorly reachable (Inferred) |
Evidence & confidence
- Verified: Illegal status: 3 copies of Dimension Shifter, banlist Forbidden, legal copies 0; Main 55 and Extra 15 within OCG size rules; Side 0 (no side deck); Exact archetype purity 0 percent with 70 off-archetype copies; Role tags: 6 hand traps, 9 tech, 6 floodgates, 4 searchers, 19 negation, 16 removal
- Observed: Archetype usage stats show Lswarm and Utopia core cards at 100 percent inclusion, but none are run at the typical count
- Inferred: Brick and consistency read from copy histogram and probability table; Interaction quality read from card text; Going-second hand-trap estimate (about 0.52) from the probability table
- Provisional: Meta Power and D13 matchup fit, since no dated meta sample exists
- 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; going-first, going-second and matchup rates are unknown No Side Deck supplied, so post-side performance cannot be assessed No guides for the archetype (0 mentions) Meta Power is provisional without a dated metagame sample
