Legality
Main 58 / Extra 9 / Side 0 — status: Illegal. 7 violation(s).
Identity & game plan
- Win condition: Orcust Link and Xyz boards (Galatea-I, Enlilgirsu, Dingirsu) plus Ritual boss Ame no Murakumo no Mitsurugi (3200 ATK), which can wipe the opponent's monsters on Special Summon; Nibiru, the Primal Being and Mitsurugi Ritual lines for a late-game board
- Turn 1 (going first): Open Orcust Harp Horror or Girsu, the Orcust Mekk-Knight, or a Mitsurugi searcher, then build a Link Monster such as Galatea-I or Enlilgirsu from the Orcust core. The deck has no recorded boards, so this line is text-derived.
- Turn 2 (going second): Respond with Ash Blossom, Droll & Lock Bird, Solemn Judgment, Solemn Strike, or Nibiru to disrupt the opponent's summons, then rebuild through Orcustrated Return or Orcustrated Babel. The 6-card hand has a 55% chance of holding a hand trap.
- Recovery: Recover through Orcustrated Return (draw 2), Orcustrated Babel (returns from the GY), Mitsurugi searchers, and Galatea-I, which can add a World Legacy monster or Orcustrated Babel back to hand.
- After siding: Not evaluable: the deck runs 0 Side Deck cards and the export has no side-deck data, so no post-side plan can be assessed.
Why it scores here
The deck can reliably open an Orcust core: the 13 archetype-core copies give about a 73% chance of at least one in a 5-card opening hand (Inferred, from the hypergeometric estimate). Its interaction density is high: 7 hand traps, 13 negation-text cards and 16 removal-text cards. Its end-board is strong on paper, with Ame no Murakumo no Mitsurugi (3200 ATK), Nibiru (3000 ATK) and Link/Xyz bosses. Two engines compete for the same slots, though. Orcust (Machine/DARK Link and Xyz) and Mitsurugi (Reptile Ritual tributes) need different materials, and the exact-name Orcust purity is only 17.9%. Popularity and archetype share were not used as evidence, and card scores were not averaged. The list is illegal (copy limits and two Forbidden cards), so the score is capped at 30 as a theoretical, structural-only read; the score does not reflect a playable deck.
Dimension scores
| # | Dimension | Score | Evidence |
|---|---|---|---|
| D1 | Engine Accessibility & Consistency | 60 | P(at least 1 of 13 core copies in a 5-card hand) = 0.73; a second engine dilutes the core (Inferred) |
| D2 | Opening-Hand Quality & Brick Management | 45 | P(no core card in hand) = 0.27 proxy brick rate; Ritual and Link lines conflict in hand (Inferred) |
| D3 | Combo Conversion & Ceiling | 55 | No recorded boards; ceiling read from card text: Mitsurugi Ritual into Ame no Murakumo, plus Dingirsu/Enlilgirsu extensions (Inferred) |
| D4 | Combo Floor & Median Output | 40 | combos_evidence has 0 parseable boards, so median output is unknown and set low (Inferred) |
| D5 | Interruption Resilience & Route Redundancy | 55 | 7 hand traps and 13 negation-text cards give several independent answers, but counts are illegal (Inferred) |
| D6 | Resource Economy, Recovery & Grind | 50 | Orcustrated Return and Babel recover cards, but no resource signature data exists (Inferred) |
| D7 | End-Board & Interaction Quality | 65 | 16 removal-text and 13 negation-text cards plus Orcust Crescendo and Mitsurugi Great Purification (Inferred, semantic from text) |
| D8 | Going-Second & Board-Breaking Power | 60 | Going-second hand trap P(at least 1 of 7 in 6 cards) = 0.56; Nibiru and Ame no Murakumo add board-breaking (Inferred) |
| D9 | Offensive Pressure & Closing Power | 60 | End-board ATK from Ame no Murakumo (3200), Nibiru (3000), Dingirsu (2600), Enlilgirsu (2600) (Verified stats) |
| D10 | Main Deck Efficiency & Flexibility | 45 | 58 Main Deck cards across 32 distinct cards, 18% exact-archetype purity, 17 tech and 17 searcher cards (Verified counts) |
| D11 | Extra Deck Efficiency & Coverage | 60 | 9 Extra Deck cards: 8 Link, 1 Xyz; several are Orcust-compatible, and S:P Little Knight is Limited (Verified) |
| D12 | Side Deck Adaptability | 20 | 0 Side Deck cards and no post-side data, so adaptability cannot be scored (Provisional) |
| D13 | Matchup Coverage & Format Fit | 50 | No tournament link and no dated metagame sample; archetype share unavailable (Provisional) |
| D14 | Pilotability & Error Tolerance | 35 | Two engines (Ritual tributes and Link/Xyz material) with many conditional lines are hard to pilot (Inferred) |
How the score was computed
Strategy profile: Midrange primary, Toolbox secondary, applied as the Midrange weight table. Structural ≈ 52, Going First ≈ 50, Going Second ≈ 56, Meta = provisional, Tournament Reliability ≈ 40. Modifiers: banlist_exposure (-6); engine_conflict (-4); hard_garnet_burden (-2). Final formula: Illegal cap applied. Uncapped: 0.80*Structural(52) + 0.20*TournamentReliability(40) + Modifiers(-12) = 37.6; capped to 30 per the illegal-deck rule (theoretical/structural-only). Meta Power provisional.
Probability & combo summary
- Opening a starter: P(≥1) ≈ 0.73 · key two-card combo ≈ — · full-brick estimate ≈ 0.27 (all Inferred)
- Combo output: best PowerIndex —, median —, board-per-starter —
- Turn order: 0 going-first lines vs 0 going-second lines
Strengths
- 13 archetype-core copies give about a 73% chance of at least one in a 5-card opening hand
- 7 hand traps plus 13 negation-text cards give layered interaction
- Strong end-board ATK from Ame no Murakumo, Nibiru and Link/Xyz bosses
- Recovery via Orcustrated Return and Orcustrated Babel
Weaknesses
- Illegal list: two Forbidden cards and five over-limit Limited or Semi-Limited cards
- Two engines (Orcust Link/Xyz and Mitsurugi Ritual) with conflicting material
- Exact-archetype purity of 17.9%
- No Side Deck, so no post-side adaptability
- No recorded combos, so consistency and conversion are text-inferred
Critical choke points
- Ritual Summon of Mitsurugi bosses depends on Mitsurugi Ritual and Reptile tributes, which the Orcust line does not supply
- A 27% full-brick proxy from the core-card probabilities
- Forbidden and over-limit cards mean the list cannot be played as built
Recommended changes
| Priority | Remove | Add | Reason |
|---|---|---|---|
| 1 | Called by the Grave (1), Triple Tactics Talent (1) | Nothing; both are Forbidden | Forbidden cards make the list illegal in OCG |
| 2 | Pre-Preparation of Rites (1), Mitsurugi Prayers (2), Super Polymerization (1), Ash Blossom & Joyous Spring (1), Droll & Lock Bird (1) | Nothing; reduce to legal copy limits | Brings the Main Deck to 49 cards, still within the 40-60 size range, and makes the list legal |
| 3 | Pick one engine (Orcust or Mitsurugi) and cut the other's support cards | Add a Side Deck of 10-15 cards | Reduces engine conflict and gives post-side adaptability (D12) something to score |
Evidence & confidence
- Verified: Main Deck 58 cards, Extra Deck 9 cards, Side Deck 0 cards; Seven cards over their OCG legal copy limit; Called by the Grave and Triple Tactics Talent are Forbidden; Core-card probabilities from the hypergeometric table
- Inferred: Starter consistency (73%) and brick proxy (27%) are estimates, not measured rates; Hand-trap access (55% going second) is estimated; Interaction density is read semantically from card text; Ceiling and median are text-derived because no combos were recorded
- Provisional: Meta Power (no dated metagame sample); Matchup and format fit (no tournament link); Post-side plan (no Side Deck)
- Data gaps: no combos supplied; combo floor, median and ceiling are text-only inference no tournament link; archetype meta-share and per-pilot record absent no win-rate telemetry; going-first, going-second, matchup and brick rates are Inferred or Unknown Meta Power is provisional without a dated metagame sample Side Deck is empty, so no post-side evaluation is possible
