Legality
Main 40 / Extra 15 / Side 0 — status under the rules at evaluation time: Illegal. 5 violation(s).
Identity & game plan
- Win condition: Orcust and Mitsurugi board development into high-ATK monsters (Ame no Murakumo no Mitsurugi 3200, Super Starslayer TY-PHON 2900, Dingirsu 2600) and Link-based pressure; Orcust Link recursion and Galatea-I / Orcustrated Babel loops to rebuild the board after interruption
- Turn 1 (going first): Normal Summon an Orcust or Mitsurugi starter, use Orcust Harp Horror or Girsu to pull or summon into a Link or Xyz line, and keep Ash Blossom and Dominus Impulse up as interaction
- Turn 2 (going second): Open with Droll & Lock Bird, Maxx C or Ash Blossom to slow the opponent's summons, then rebuild through Orcust GY effects and Extra Deck summons
- Recovery: Banish-based Orcust effects (Harp Horror, Cymbal Skeleton, Knightmare) to re-summon from the GY, and Orcustrated Babel to recycle
- After siding: No side deck is listed, so there is no post-side plan to evaluate
Why it scores here
The list reliably reaches an Orcust engine: the archetype core group has a 0.995 chance of at least one copy in a 5-card opening hand, so the deck usually has a starter, though any single specific 3-copy card is only about 0.34 likely in the opening hand. Its main interaction (Ash Blossom, Dominus Impulse, Droll & Lock Bird, Maxx C, Orcust Crescendo) gives it real disruption, and the going-second hand-trap group has about 0.76 odds of at least one hit. Its ceiling is credible from card text (Murakumo, TY-PHON and Dingirsu) but the deck has no recorded boards, so median output is unmeasured and inferred. The score is capped because the list is illegal: three Ame no Habakiri, three Mitsurugi Prayers, three Droll & Lock Bird, two Maxx C and two Called by the Grave (Forbidden) exceed the Master Duel limits, and the deck has no side deck. Popularity and archetype usage were not counted as power, and the card scores were not averaged.
Dimension scores
| # | Dimension | Score | Evidence |
|---|---|---|---|
| D1 | Engine Accessibility & Consistency | 62 | P(at least one of a 3-copy card in 5-card hand) ≈ 0.34; archetype core P(open ≥1) ≈ 0.995 (Inferred) |
| D2 | Opening-Hand Quality & Brick Management | 52 | 40 main with 22 distinct cards, 12 singletons and 8 three-of cards; 53 off-archetype copies, and conflicting Mitsurugi and Orcust starters (Inferred) |
| D3 | Combo Conversion & Ceiling | 60 | Ceiling from card text only: Murakumo, Ritual + Mitsurugi Ritual, Orcust Link loops; no recorded boards (Inferred) |
| D4 | Combo Floor & Median Output | 45 | No combos_evidence; median output is not measured and is estimated from starter density only (Inferred) |
| D5 | Interruption Resilience & Route Redundancy | 58 | Two Maxx C/Droll-style interruptions, Ash Blossom and Orcust Crescendo; GY recursion via Harp Horror and Cymbal Skeleton (Inferred) |
| D6 | Resource Economy, Recovery & Grind | 60 | Orcust GY banish effects, Orcustrated Babel and Galatea-I-style recursion from text; no resource signature data (Inferred) |
| D7 | End-Board & Interaction Quality | 65 | Dominus Impulse, Orcust Crescendo, Ash Blossom, Droll & Lock Bird and Murakumo negation text; flag-based count only (Inferred) |
| D8 | Going-Second & Board-Breaking Power | 62 | Going-second hand-trap group P(≥1 in 6-card hand) ≈ 0.76; board-breaking from Murakumo destroy effect text (Inferred) |
| D9 | Offensive Pressure & Closing Power | 62 | Boss ATK from card stats: Murakumo 3200, TY-PHON 2900, Dingirsu 2600, Longirsu 2500; no closing data (Verified stats / Inferred) |
| D10 | Main Deck Efficiency & Flexibility | 48 | Main 40 is legal in size, but 4 off-archetype tech and splash slots and 53 off-archetype copies lower compactness (Inferred) |
| D11 | Extra Deck Efficiency & Coverage | 60 | Extra 15: 11 Link and 4 Xyz, with many Orcust and Knightmare Extra options; 11 Extra cards absent from main (Verified composition / Inferred) |
| D12 | Side Deck Adaptability | 15 | No side deck (side_count 0), so there is no post-side adaptability to score (Verified gap) |
| D13 | Matchup Coverage & Format Fit | 40 | No tournament_context or dated meta sample; archetype usage used only as context (Provisional) |
| D14 | Pilotability & Error Tolerance | 45 | Multiple Link and Xyz lines, many decision points, and several copy-limit interactions to track (Inferred) |
How the score was computed
Strategy profile: Midrange. Structural ≈ 55, Going First ≈ 50, Going Second ≈ 58, Meta = provisional, Tournament Reliability ≈ 45. Modifiers: banlist exposure (-8); no side deck (-4). Final formula: Illegal list: structural-only. Structural 55 and TR 45 give 0.80*55 + 0.20*45 = 53, plus modifiers -12 = 41, capped at 35 because the list is illegal.
Probability & combo summary
- Opening a starter: P(≥1) ≈ 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
- Orcust core is almost always present (archetype core P(open ≥1) ≈ 0.995)
- Eight hand traps and multiple negation effects give real going-second interaction
- Strong top-end boss options in Murakumo, TY-PHON and Dingirsu
- Extra Deck of 15 gives Link and Xyz coverage with recursion routes
Weaknesses
- List is illegal: five cards exceed their copy limits, including a Forbidden card
- No side deck, so no best-of-3 adaptability
- Split between Orcust, Mitsurugi and World Legacy reduces starter consistency
- Several cards in the Extra Deck (Galatea-I, Enlilgirsu) are missing from the Main Deck despite high usage
Critical choke points
- Starter density: no single 3-copy card is more than about 0.34 likely in the opening hand
- Illegal copy counts: the list cannot be played as built until fixed
- Dependence on the Orcust Link loop with no combo data to confirm it works
Recommended changes
| Priority | Remove | Add | Reason |
|---|---|---|---|
| 1 | Called by the Grave (x2) | Remove, since it is Forbidden in Master Duel | A Forbidden card makes the list illegal in this format |
| 2 | Ame no Habakiri no Mitsurugi (3 to 2), Mitsurugi Prayers (3 to 1), Droll & Lock Bird (3 to 2), Maxx C (2 to 1) | Replace the excess copies with Orcust or Mitsurugi playables already on the usage list | Brings all copy limits to legal and restores the deck to a playable state |
| 3 | Off-archetype tech slots | Galatea-I, the Orcust Automaton (100% usage inclusion, 0 copies in this deck) | Restores a core Orcust Link starter that usage statistics show is standard in the archetype |
| 4 | None (side deck is empty) | A 15-card side deck with Orcust and Mitsurugi interaction | Gives best-of-3 adaptability and a post-side plan, which the list currently lacks |
Evidence & confidence
- Verified: Legality: copy-limit violations and Called by the Grave Forbidden status; Main 40, Extra 15, side 0 counts; Card text and stats from the card list; Archetype usage: Galatea-I 100% inclusion, 0 copies in this deck
- Inferred: Hypergeometric starter and brick estimates; Combo ceiling from card text; Interaction density and going-second read from text flags
- Provisional: Meta and matchup fit (no dated sample); Tournament reliability
- Data gaps: No combos supplied, so floor, median and ceiling are text-only inference No tournament link, so no meta-share or per-pilot record No side deck (side_count 0) No win-rate telemetry exists in YGOVN Meta Power is Provisional unless a dated metagame sample is supplied
