Legality
Main 42 / Extra 15 / Side 0 — status under the rules at evaluation time: Illegal. 2 violation(s).
Identity & game plan
- Win condition: Xyz/Link board from Lswarm starters into Evilswarm Ophion, Evilswarm Bahamut and Dark Armed Dragon; Arc Rebellion Xyz Dragon and Odd-Eyes Raging Dragon as 3000-ATK closers after Raigeki or Feather Duster clears
- Turn 1 (going first): Normal Summon Evilswarm Kerykeion or Heliotrope, then Normal Summon a second Lswarm via Castor or Mandragora, then Xyz into Ophion to search an Infestation Spell/Trap
- Turn 2 (going second): Use Monster Reborn, Rescue Rabbit or Bystial Magnamhut to reach a board, then Exciton Knight or Bahamut to clear backrow and interact
- Recovery: Lair of Darkness and Kerykeion recursion, Ahrima and Duke Shade draws, Ophion searches for Infestation Pandemic
- After siding: Not evaluable: the deck has no Side Deck, so there is no post-side plan
Why it scores here
The deck opens a playable Lswarm Level 4 board through three to four starters (Kerykeion, Heliotrope, Castor, Mandragora), each at 3 or 2 copies, so going-first starter access is moderate rather than reliable (Inferred). It converts into 3000-ATK closers and strong Extra Deck coverage, but the engine splits across Steelswarm, Bystial, Harpie, Armed Dragon and Phantom Knights rather than running a single core. Interaction is broad on paper (Raigeki, Feather Duster, Solemn, Exciton Knight destruction, Bahamut control), yet it has no hand traps and no Side Deck, so resilience and post-side adaptability stay low. Popularity was not credited: the Evilswarm usage core is absent from this list and the score comes from the system's consistency and interaction, not from averaging card scores. The deck is Illegal (Solemn Judgment over-limited, Called by the Grave Forbidden), so the score is capped and reflects a structural read only.
Dimension scores
| # | Dimension | Score | Evidence |
|---|---|---|---|
| D1 | Engine Accessibility & Consistency | 50 | Four starters at 2-3 copies each, P(>=1 Kerykeion in 5-card hand) 0.32; union across starters not computed; no combos supplied (Inferred) |
| D2 | Opening-Hand Quality & Brick Management | 45 | Eight searcher-text cards and 13 singletons, but Power Filter, Mask of Restrict and Infestation Pandemic are weak in hand and there are no hand traps (Inferred) |
| D3 | Combo Conversion & Ceiling | 55 | No parseable combos; ceiling from card text only: Ophion search, Bahamut control steal, Arc Rebellion negation (Inferred, text-only) |
| D4 | Combo Floor & Median Output | 40 | No recorded boards, so median output is unknown and set low for confidence (Inferred, text-only) |
| D5 | Interruption Resilience & Route Redundancy | 40 | No hand traps or floodgates; recovery from Thunderbird, Rescue Rabbit and Kerykeion recursion only (Inferred) |
| D6 | Resource Economy, Recovery & Grind | 45 | Recursion from Kerykeion and Lair of Darkness, plus Ahrima and Duke Shade draws; no resource signature data (Inferred) |
| D7 | End-Board & Interaction Quality | 60 | Raigeki, Feather Duster, Exciton Knight destruction and Bahamut control; Solemn over-limit and Called by the Grave Forbidden reduce it (Inferred) |
| D8 | Going-Second & Board-Breaking Power | 50 | Raigeki and Dark Armed Dragon removal, Bystial Baldrake and Magnamhut as board-breakers; no going-second split data (Inferred) |
| D9 | Offensive Pressure & Closing Power | 60 | Arc Rebellion 3000 ATK, Odd-Eyes 3000 ATK, Ophion 2550 ATK, Bahamut 2350 ATK; closing exists but relies on one-copy Extra Deck cards (Verified stats, Inferred use) |
| D10 | Main Deck Efficiency & Flexibility | 45 | 42 main cards within the 40-60 range, but 24 distinct cards split across five sub-archetypes with 4 Normal Monsters and dead-ish Spells (Verified counts, Inferred coherence) |
| D11 | Extra Deck Efficiency & Coverage | 55 | Ten distinct Extra Deck cards across Xyz, Link and Pendulum with Ophion at 3 copies; coverage good, slot use reasonable (Verified composition) |
| D12 | Side Deck Adaptability | 15 | No Side Deck at all (0 of 15 slots), so best-of-3 adaptation is absent (Verified) |
| D13 | Matchup Coverage & Format Fit | 45 | No tournament link or dated meta sample; archetype share unknown (Provisional) |
| D14 | Pilotability & Error Tolerance | 40 | Chain-heavy Lswarm sequencing with many optional Normal Summon decisions and Xyz material choices (Inferred) |
How the score was computed
Strategy profile: Midrange. Structural ≈ 47, Going First ≈ 44, Going Second ≈ 41, Meta = provisional, Tournament Reliability ≈ 40. Modifiers: banlist exposure (-10); no side deck (-2). Final formula: Illegal deck: theoretical/structural-only. 0.80*Structural + 0.20*TournamentReliability + ContextModifiers = 45.6 - 12 = 33.6, then capped to 30 for illegality (Meta provisional)
Probability & combo summary
- Opening a starter: P(≥1) ≈ — · 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 Lswarm Level 4 starter package with multiple Normal Summon extenders
- Strong 3000-ATK closers and broad Extra Deck coverage across Xyz, Link and Pendulum
- Multiple interaction spells (Raigeki, Feather Duster, Monster Reborn, Solemn) with a board-clearing ceiling
Weaknesses
- Illegal list: Solemn Judgment over-limit and Called by the Grave Forbidden
- No hand traps and no Side Deck
- Split sub-archetype engine (Steelswarm, Bystial, Harpie, Armed Dragon, Phantom Knights) reduces cohesion
Critical choke points
- Three to four starters are the only T1 Lswarm access; no hand trap backup if they are dead
- Going second has no hand trap; Ophion chain depends on a Level 4 pair
Recommended changes
| Priority | Remove | Add | Reason |
|---|---|---|---|
| 1 | 2x Called by the Grave | Legal non-Forbidden backrow or hand trap | Forbidden card makes the list Illegal; removing it is a required fix |
| 2 | 1x Solemn Judgment | Keep at 1 copy only | Limited to 1 copy in MD; the 3-copy run is an Illegal violation |
| 3 | Power Filter or Mask of Restrict | Side deck of up to 15 cards | Adds post-side adaptability and reduces weak non-starters |
Evidence & confidence
- Verified: Main 42 / Extra 15 / Side 0 counts and size rules; Solemn Judgment over-limit and Called by the Grave Forbidden; Card stats and per-card hypergeometric probabilities from the evidence
- Inferred: Starter consistency and brick rate; Interaction quality from card text; Going-first and going-second estimates
- Provisional: Meta Power and matchup fit (no dated sample)
- Data gaps: no combos supplied: floor, median and ceiling are text-only inference no tournament link: archetype meta-share and per-pilot record absent no Side Deck: post-side and best-of-3 plans cannot be evaluated no win-rate telemetry: going-first/second and matchup signals are Inferred Meta Power is Provisional unless a dated metagame sample is supplied
