Orcust Deck #774376 — Yu-Gi-Oh! Master Duel

Deck — Deck Power Evaluation

Final Contextual Deck Power: 60/100 (±6 · Confidence: Medium)

• Primary strategy: Midrange
• Secondary strategies: Stun, Toolbox
• Format: master-duel

Legality

Main 45 / Extra 15 / Side 0 — status: Legal.

Identity & game plan

• Win condition: Link and Extra Deck boss pressure (Enlilgirsu, Galatea, Zombie Vampire, Red-Eyes Dark Dragoon, Dark Magician of Destruction) built from Orcust Machine engines; Mekk-Knight / Phantom Knights / Dark Magician sub-engines feeding Extra Deck summons
• Turn 1 (going first): Open an Orcust Harp Horror, Girsu, Phantom Knights of Doomed Soleret, Mulcharmy Fuwalos or Dark Magician Girl to extend and reach a Link or Xyz boss; keep Ash/Droll/Maxx for the opponent's first Quick Effect or hand-search
• Turn 2 (going second): Hold Ash Blossom, Droll & Lock Bird and Maxx "C" to break the opponent's first Special Summon or search, then use Dominus Impulse, Forbidden Droplet or Crescendo to protect the engine before extending
• Recovery: Orcustrated Return and Orcustrated Babel recycle Orcust monsters; Mulcharmy draw effects and Galatea-I search rebuild the hand; banished Machines and GY Orcusts feed Galatea and Longirsu
• After siding: No sideboard in this format (Side Deck size 0); no post-side plan is available

Why it scores here

The deck reliably opens an Orcust starter in most hands: six 3-copy starters (Dark Magician Girl, Orcust Harp Horror, Girsu, Phantom Knights of Doomed Soleret, Mulcharmy Fuwalos, Ash Blossom as a hand-trap) give a hypergeometric P(at least one 3-copy card in an opening 5) of about 0.30 each, and a 21-card opening-enabler set puts P(at least one enabler in 5) near 0.97 (Inferred). Interaction is the strongest part of the system: six hand traps, Dominus Impulse, Forbidden Droplet, Crescendo and Umbrage Veil give going-second coverage, and the Extra Deck carries several high-ATK bosses that can close. The score comes from consistency, interaction density and closing power on the whole system; it does not come from Orcust being a popular archetype, and no card scores were averaged. Scoring is held back by a 20% exact-archetype purity (Mekk-Knight, Phantom Knights, Mulcharmy, Shining Sarcophagus and Dark Magician engines run together), no recorded boards to measure combo output, and no sideboard or meta sample, so the uncertainty band is wide.

Dimension scores

How the score was computed

Strategy profile: Midrange profile with D13 dropped and weights renormalized to 95 (no meta sample). Structural ≈ 64, Going First ≈ 66, Going Second ≈ 64, Meta = provisional, Tournament Reliability ≈ 60. Modifiers: banlist exposure (-1); engine_conflicts_low_purity (-2). Final formula: 0.80*Structural + 0.20*TournamentReliability + ContextModifiers (Meta provisional)

Probability & combo summary

• Opening a starter: P(≥1) ≈ 0.97 · key two-card combo ≈ — · full-brick estimate ≈ 0.12 (all Inferred)
• Combo output: best PowerIndex —, median —, board-per-starter —
• Turn order: 0 going-first lines vs 0 going-second lines

Strengths

• Six hand traps plus Dominus Impulse and Forbidden Droplet give real going-second interaction
• Multiple 3-copy starters with Mulcharmy and Orcustrated Return draw support
• Extra Deck has several high-ATK bosses and 11 Link options for flexible summons

Weaknesses

• 20% exact-archetype purity; sub-engines (Mekk-Knight, Phantom Knights, Shining Sarcophagus, Dark Magician) compete for slots
• No sideboard, so no post-side adaptation
• No recorded boards, so the combo ceiling and median cannot be measured

Critical choke points

• Triple Tactics Talent and Gandora-G are conditional and can be dead in the wrong state
• Shining Sarcophagus and Future Silence depend on each other for their main effect

Evidence & confidence

• Verified: Legal in master-duel, 45 main / 15 extra / 0 side with no violations; Restricted cards Crossout Designator, Foolish Burial and Maxx "C" at 1 copy (Limited), Droll & Lock Bird at 2 (Semi-Limited); Extra Deck ATK values for Zombie Vampire, Red-Eyes Dark Dragoon, Dark Magician of Destruction and Enlilgirsu
• Observed: Composition: 27 distinct main cards, 15 singletons, 6 hand traps, 10 searchers by text; Extra Deck breakdown 11 Link, 2 Fusion, 2 Xyz
• Inferred: P(at least one 3-copy starter in 5 cards) ≈ 0.30; enabler set ≈ 0.97 on going-first hand; Full brick ≈ 0.12; Structural ≈ 64 with D13 dropped and renormalized
• Provisional: Meta Power (null, no dated metagame sample); D13 matchup and format fit (neutral, excluded from Structural)
• Data gaps: No combos supplied: combo floor, median and ceiling are text-only inference No tournament link: archetype meta-share and per-pilot match record absent No win-rate telemetry (going-first/second, matchup, brick/starter rates) Usage statistics mark Knightmare Mermaid, Enlilgirsu, Galatea-I, Galatea, Longirsu, I:P Masquerena, S:P Little Knight, Knightmare Phoenix and Dingirsu as in this deck:false, but the card list shows them in the Extra Deck; the two sources disagree, and the card list was used Guide 1235 mentions Fiendsmith combos, but no Fiendsmith cards appear in this deck list Master Duel has no sideboard, so D12 is neutral rather than measured
