Orcust Deck #773561 — Yu-Gi-Oh! Master Duel

Deck — Deck Power Evaluation

Final Contextual Deck Power: 64/100 (±6 · Confidence: Medium)

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

Legality

Main 40 / Extra 15 / Side 0 — status: Legal.

Identity & game plan

• Win condition: Link/Xyz/Fusion boss pressure from the Extra Deck (Dingirsu, Enlilgirsu, Red-Eyes Dark Dragoon, Dark Magician of Destruction, The Zombie Vampire) once the Orcust GY engine (Harp Horror, Cymbal Skeleton, Knightmare) has produced a live board; Repeated Orcust/World Legacy recursion through Girsu, Orcustrated Babel and Galatea-I to rebuild after disruption
• Turn 1 (going first): Open a 3-copy starter (Harp Horror, Girsu, Dark Magician Girl, Shining Sarcophagus), search or self-summon into a Link or Xyz boss, and keep Ash, Impermanence and Dominus Impulse as protection for the follow-up
• Turn 2 (going second): Use Ash Blossom, Infinite Impermanence, Dominus Impulse, Droll and Maxx C to answer the opponent's first summons, then rebuild the Orcust engine from the GY
• Recovery: Banish Orcust monsters from the GY for their GY effects (Harp Horror, Cymbal Skeleton, Knightmare), and use Orcustrated Babel and Galatea-I to recover searches
• After siding: No side deck is registered (side 0), so there is no post-side plan in the list; the main deck must carry all matchups

Why it scores here

The deck was scored as a connected system on Midrange weights, not as an average of its cards. Its consistency comes from 12 copies of four 3-of starters (Harp Horror, Girsu, Dark Magician Girl, Shining Sarcophagus), which gives roughly an 85% chance of at least one starter in a going-first five-card hand (Inferred hypergeometric). Interaction is the strongest part of the build, with eight hand traps and about a dozen negation or removal texts that can answer a first summon on either turn. The Extra Deck (15 cards, 11 Link) gives several independent boss routes, so the deck has recovery paths after one disruption. Popularity was not credited: the Orcust archetype is widely played, but archetype usage stats were not used as evidence of power. Combo ceiling and median are unmeasured because no recorded boards exist, and the empty side deck and the lack of any dated meta sample cap the final score.

Dimension scores

How the score was computed

Strategy profile: Midrange. Structural ≈ 64.5, Going First ≈ 70, Going Second ≈ 66, Meta = provisional, Tournament Reliability ≈ 58. Modifiers: engine compactness (2); unrecoverable choke point (-1). Final formula: 0.80*Structural + 0.20*TournamentReliability + ContextModifiers (Meta provisional, no dated sample)

Probability & combo summary

• Opening a starter: P(≥1) ≈ 0.85 · key two-card combo ≈ — · full-brick estimate ≈ 0.15 (all Inferred)
• Combo output: best PowerIndex —, median —, board-per-starter —
• Turn order: 0 going-first lines vs 0 going-second lines

Strengths

• Four 3-of starters give high going-first starter access
• Eight hand traps plus negation text give layered interaction on either turn
• Multiple Extra Deck boss routes (Link, Xyz, Fusion) with full Extra Deck usage
• Orcust GY recursion gives resilience after disruption

Weaknesses

• No side deck registered, so no post-side plan
• Many dead-in-hand interaction cards when going first
• Engine is split across sub-archetypes (20% exact-name purity)
• No recorded boards, so the combo ceiling and median cannot be verified

Critical choke points

• Orcust Harp Horror and Girsu copies in hand for going-first starter access
• Galatea-I and Orcustrated Babel for recovering searches after a broken board

Recommended changes

Evidence & confidence

• Verified: Legal main 40, extra 15, side 0 under master-duel size rules; All Limited and Semi-Limited copies are within legal copies; Copy histogram 8×3, 2×1, 14×1 (Main Deck totals 40); Extra Deck contains 11 Link, 2 Fusion and 2 Xyz monsters
• Observed: 6 guides attached for the Orcust archetype (count only, no content analysed)
• Inferred: P(≥1 starter in going-first 5) ≈ 0.85; Interaction density scored from card text (8 hand traps, 12 negation texts); Engine route scoring from card text and GY recursion
• Provisional: Meta Power is null; D13 is provisional without a dated sample; Post-side plan is provisional because no side deck is registered
• Data gaps: No recorded boards: combo data has 0 scored combos, so D3 and D4 rest on text inference usage statistics in this deck flags contradict the card list: Galatea-I, Dingirsu, Enlilgirsu, Knightmare Phoenix, S:P Little Knight, Mermaid, Longirsu, I:P Masquerena and Galatea are present in the Extra Deck list but marked in this deck false, so missing core cards and core-card presence are unreliable; the card list was used No tournament link: archetype meta-share and per-pilot match record absent No win-rate telemetry: going-first/second, matchup and brick rates are Inferred or Unknown Meta Power is Provisional without a dated metagame sample No side deck registered
