Orcust Deck #770325 — Yu-Gi-Oh! Master Duel

Deck — Deck Power Evaluation

Final Contextual Deck Power: 59/100 (±7 · Confidence: Medium)

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

Legality

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

Identity & game plan

• Win condition: Orcust Link and Xyz chain (Girsu, Harp Horror, Galatea-I, Dingirsu) converting into 2500-2800 ATK boards (Dingirsu, Enlilgirsu, Longirsu, Caesar); Fiendsmith Lacrima and Snake-Eye Doomed Dragon as alternate boards; Nibiru and World Crown as late-game boss threats
• Turn 1 (going first): Open with Harp Horror or Girsu plus a summon-enabling card, then Link into an Orcust Link Monster; keep hand traps for the opponent's first real activation rather than spending them on turn 1
• Turn 2 (going second): Use the 13 hand traps (Ash, Ghost Ogre, Ghost Belle, Impermanence, Droll, Maxx C, Nibiru) to disrupt the opponent's first board, then rebuild through Harp Horror and Girsu
• Recovery: Orcustrated Babel and Harp Horror banish from the GY recur Orcust cards; Fiendsmith's Tract and Mulcharmy draw add cards after a disruption
• After siding: No side deck is run in Master Duel; adaptation is limited to the 40-card main

Why it scores here

The score comes from the system: a live Orcust starter (Harp Horror or Girsu, six copies) appears in about 58% of going-first five-card hands (hypergeometric, Inferred), and 13 hand traps make interruption and going-second disruption strong (about 92% chance of at least one hand trap in a going-second six-card hand). The Extra Deck gives several independent closers, including Dingirsu, Enlilgirsu, Caesar, Snake-Eye Doomed Dragon and Nibiru. Against that, the deck mixes Orcust, Fiendsmith, Knightmare, Millennium, Mulcharmy and World Legacy pieces (only 11 of 40 main copies are exact-name Orcust), which lowers the median and raises brick and pilot-error risk. No combo boards were recorded, so the ceiling and median are text-only inference. Popularity and the Orcust guides confirm the list is a real, accessible build but did not add points, and card scores were not averaged into the deck score.

Dimension scores

How the score was computed

Strategy profile: Pure Midrange profile; Stun and Toolbox traits are noted but not blended. Structural ≈ 61.7, Going First ≈ 56, Going Second ≈ 72, Meta = provisional, Tournament Reliability ≈ 55. Modifiers: engine conflict (-3); hand-trap density (2). Final formula: 0.80*Structural + 0.20*TournamentReliability + ContextModifiers (no metagame sample; Meta provisional; Structural renormalized without D13: 5859/95 = 61.7)

Probability & combo summary

• Opening a starter: P(≥1) ≈ 0.58 · 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

• Thirteen hand traps give strong going-second disruption (about 92% access)
• Multiple Extra Deck closers at 2600-3000 ATK
• Orcust recursion (Babel, Harp Horror, Cymbal) supports repeated plays
• Compact Extra Deck with 11 Link routes and no dead Synchro requirements

Weaknesses

• Only 11 of 40 main copies are exact-name Orcust, so the engine is spread across families
• Thirteen hand traps are weak when going first without opposing summons
• Fiendsmith and Knightmare pieces need their own support lines
• No side deck and no recorded combo data to confirm the floor

Critical choke points

• Harp Horror or Girsu in the opening hand (about 58% for five cards)
• Mulcharmy and Fiendsmith pieces as the only secondary starts
• Single Orcust Link Monster needed to convert the Xyz and Link lines

Recommended changes

Evidence & confidence

• Verified: Legal status with 40 main, 15 extra, 0 side; four restricted cards at legal copy limits; Composition: 11 Link, 2 Fusion, 2 Xyz, 0 Synchro; 13 hand traps; Usage statistics show 25 core cards with 15 present by name, with ID-match conflicts noted
• Inferred: P(at least one Harp Horror or Girsu in 5) ≈ 0.58; Hand-trap access about 92% going second; Going-first hand-trap dead-draw risk; Ceiling and floor from card text only (no combos)
• Provisional: Meta Power (no dated metagame sample); Matchup fit and side-deck value (no tournament data)
• Data gaps: No combos supplied; combo floor, median and ceiling are text-only inference usage_statistics.in_this_deck is false for Galatea-I, Dingirsu, Knightmare Phoenix, Knightmare Mermaid, Enlilgirsu, I:P Masquerena, Longirsu and S:P Little Knight, but these appear in cards[] (zone extra); core_present_pct 60 is unreliable No tournament link; archetype meta-share and per-pilot records absent No win-rate telemetry; going-first/second and matchup signals are inferred Meta Power is provisional without a dated metagame sample
