Orcust Deck #765399 — Yu-Gi-Oh! Master Duel

Deck — Deck Power Evaluation

Final Contextual Deck Power: 57/100 (±6 · Confidence: Medium)

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

Legality

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

Identity & game plan

• Win condition: Link and Xyz boards built from Orcust, Fiendsmith and Mekk-Knight engines, closed by Dingirsu, Lacrima, Requiem and Sengenjin-level bodies; Fusion pressure via Fiendsmith's Lacrima and Snake-Eyes Doomed Dragon, with Mulcharmy draw pressure
• Turn 1 (going first): Open on a 2-body Orcust or Fiendsmith starter (Harp Horror, Girsu, Engraver), extend into a link or xyz board, and hold a hand trap for the next Summon
• Turn 2 (going second): Use the 10 hand traps and Droll & Lock Bird to stop the opponent's first Summon or search, then rebuild through the Orcust and Fiendsmith engines
• Recovery: Recur from the GY through Harp Horror, Cymbal Skeleton, Lacrima and Babel, and re-search with Engraver and Tract
• After siding: No side deck in this build; the list has no post-side plan and relies on the main-deck hand traps for every matchup

Why it scores here

The deck opens a live engine reliably: the 23 archetype-core copies give about a 99% chance of at least one core card in a 5-card opening hand, and the 10 searchers give about a 78% chance of a searcher in hand (both Inferred from hypergeometric estimates). Ten hand traps and two Droll & Lock Birds give about an 85% chance of at least one interaction card in a 6-card going-second hand, which earns the interruption and going-second credit. The engine redundancy across Orcust, Fiendsmith, Mulcharmy, Mekk-Knight and World Legacy is what lifts the score, not the popularity of the Orcust name, and no card scores were averaged into the deck score. Combo ceiling and median are text-only inferences because no recorded boards exist, and the Mulcharmy hand-empty conditions, the 20% exact-archetype purity and the absence of a side deck pull the score down. Meta Power is provisional and excluded, so the final score rests on structural power and tournament reliability with a Medium confidence band of plus or minus 6.

Dimension scores

How the score was computed

Strategy profile: Midrange primary, Toolbox secondary (not separately weighted). Structural ≈ 64, Going First ≈ 64, Going Second ≈ 66, Meta = provisional, Tournament Reliability ≈ 62. Modifiers: Weak post-side plan (-2); Engine conflicts (-3); Banlist exposure (-1). Final formula: 0.80*Structural + 0.20*TournamentReliability + ContextModifiers (Meta provisional): 0.80*63.8 + 0.20*62 + (-6) ≈ 57

Probability & combo summary

• Opening a starter: P(≥1) ≈ 0.99 · 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

• Core engine is almost always accessible in a 5-card opening hand
• Ten hand traps and two Droll & Lock Birds give strong going-second interaction
• Engine redundancy across five archetype lines keeps a second route alive after one disruption
• Legal list with no copy-limit violations

Weaknesses

• No side deck, so no post-side adaptation
• 20% exact-name archetype purity dilutes the engine and adds dead-draw risk
• Mulcharmy hand-empty conditions conflict with board-building engines
• Missing several Orcust core Link cards (Galatea-I, Longirsu, Enlilgirsu) present in the usage list

Critical choke points

• Mulcharmy hand-empty condition conflicts with the Orcust and Fiendsmith board plan
• Single-copy Limited cards (Maxx C, Foolish Burial, Crossout Designator) cannot be replaced by extra copies

Recommended changes

Evidence & confidence

• Verified: Legal list: 40 Main, 15 Extra, 0 Side under master-duel size rules; Copy counts and banlist statuses for Maxx C, Foolish Burial, Crossout Designator and Droll & Lock Bird; Archetype purity 20% and off-archetype copies 44; Usage stats: 14 of 25 core cards present
• Observed: Guides describe a 2-body full combo for Orcust and Fiendsmith
• Inferred: Hypergeometric access estimates (core, searcher, hand trap); Engine redundancy and interruption resilience; Going-second hand-trap access; Combo ceiling and median from text only
• Provisional: Meta Power (no dated sample); Matchup and format fit (no tournament data); Side-deck adaptability (no side deck)
• Data gaps: no combos supplied — combo floor/median/ceiling is text-only inference no tournament link — archetype meta-share and per-pilot match record absent no win-rate telemetry exists in YGOVN — going-first/second, matchup, brick and starter rates are Inferred or Unknown Meta Power is Provisional unless a dated metagame sample is supplied no side deck, so post-side performance cannot be assessed
