Orcust Deck #765888 — Yu-Gi-Oh! Master Duel

Deck — Deck Power Evaluation

Final Contextual Deck Power: 65/100 (±7 · Confidence: Medium)

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

Legality

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

Identity & game plan

• Win condition: Orcust Link/Xyz/Fusion boards (Enlilgirsu, Master of Chaos, Dark Magician of Destruction, Red-Eyes Dark Dragoon, TY-PHON, Dingirsu) built from GY-banish Orcust summons and Girsu/Harp Horror starters; Hand-trap-backed negation of the opponent's Extra Deck summons, then a board-breaking Fusion or Xyz finish
• Turn 1 (going first): Open a starter (Orcust Harp Horror, Girsu, Cymbal Skeleton, Mulcharmy draw or Dark Magician Girl), summon into a Link (Galatea, Knightmare Mermaid), and continue into a boss while holding Ash Blossom, Infinite Impermanence or Dominus Impulse for the first interruption
• Turn 2 (going second): Hold hand traps (Ash Blossom, Droll & Lock Bird, Ghost Ogre & Snow Rabbit, Maxx "C") to stop the opponent's first board, then rebuild through the GY-banish Orcust loop into a Fusion or Xyz boss
• Recovery: Use the GY-banish Orcust effects (Harp Horror, Cymbal Skeleton, Knightmare), Orcustrated Babel recursion, and Galatea-I searching to rebuild links after an opposing negate or removal
• After siding: Not applicable: Master Duel has no side deck in this format (side_count 0); post-side adaptation is Provisional

Why it scores here

The deck reliably opens a functional Orcust starter: the 29-copy archetype core gives a hypergeometric P(at least one core card in a 5-card opening hand) of about 0.999, and several independent starters (Harp Horror, Girsu, Cymbal Skeleton, the Mulcharmy draw engines) keep the first link reachable. Conversion is strong at the ceiling because the Extra Deck holds high-ATK bosses (Master of Chaos 3000, Red-Eyes Dark Dragoon 3000, TY-PHON 2900, Dark Magician of Destruction 2800) that can be reached through several Link and Xyz routes; this is an Inferred structural read because no recorded boards exist. Interaction density is high (about eleven hand traps plus Maxx "C", Foolish Burial and Orcust Crescendo), which carries the deck through a first interruption and gives it a real going-second plan. The score comes from consistency, median output and interaction on the system as a whole, not from averaging card scores, and not from Orcust being a popular archetype: the 23.6% exact-name purity and the mixed Mekk-Knight, Knightmare, Mulcharmy and Magician support lower the coherence and cap the final score.

Dimension scores

How the score was computed

Strategy profile: Combo primary, Midrange secondary (disclosed only; Combo weights used for structural score). Structural ≈ 70, Going First ≈ 68, Going Second ≈ 70, Meta = provisional, Tournament Reliability ≈ 64. Modifiers: engine conflicts (-3); banlist exposure (-1). Final formula: 0.80*Structural + 0.20*TournamentReliability (Meta provisional) + ContextModifiers = 0.80*70.1 + 0.20*64 - 4 = 64.9 -> 65

Probability & combo summary

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

Strengths

• Archetype core of 29 copies gives near-certain starter access in the opening hand
• Layered interaction: about 11 hand traps plus negate and removal text on Ash Blossom, Infinite Impermanence, Dominus Impulse, Red-Eyes Dark Dragoon and Orcust Crescendo
• Extra Deck ceiling of 2600 to 3000 ATK bosses reached through several Link and Xyz routes
• Compact 40-card main with three-copy engine and interaction cards

Weaknesses

• Low exact-name Orcust purity (23.6%) means several sub-engines compete for the same slots
• High hand-trap count raises the risk of hands with no proactive starter
• No recorded boards, so the ceiling and median are text-based inference only
• Limited Maxx "C" and Foolish Burial single-copy slots create fragile restrictions

Critical choke points

• Starter Orcust monster in hand or GY: without one of Harp Horror, Girsu, Cymbal Skeleton or Dark Magician Girl the deck has no first link
• First link summon (Galatea, Knightmare Mermaid or Knightmare Phoenix) as the gate to the Xyz and Fusion bosses
• A single opposing negate on the first boss summon with no GY-banish recovery available

Evidence & confidence

• Verified: Main Deck 40 cards, Extra Deck 15 cards, Side 0, legal in Master Duel (BanMasterDuel); Copy counts: Maxx "C" 1 (Limited, legal 1), Foolish Burial 1 (Limited, legal 1), Droll & Lock Bird 2 (Semi-Limited, legal 2); Archetype core of 29 copies and P(>=1 in 5-card hand) = 0.9993; Exact-name Orcust purity 23.6%; off-archetype 42 copies; Usage statistics: 16 of 25 core cards present, missing Longirsu, I:P Masquerena, Knightmare Phoenix, Knightmare Mermaid, Enlilgirsu, S:P Little Knight, Dingirsu, Galatea-I, Crossout Designator
• Inferred: Starter reliability from hypergeometric draw odds (Dark Magician Girl, Harp Horror, Girsu, Cymbal Skeleton); Ceiling and median from card text, since combos_evidence has zero parseable boards; Interaction quality from text regexes checked against the excerpts (negate, removal, hand trap); Going-second strength from P(>=1 hand trap in 6) = 0.876 and removal text; Engine conflict penalty from the mixed sub-archetype spread
• Provisional: Meta Power (null, no dated metagame sample); Matchup fit and tournament reliability (no tournament link or per-pilot match record); Side-deck adaptability (Master Duel has no side)
• 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 exists in YGOVN (going-first/second, matchup, brick and starter rates): these signals are Inferred or Unknown Meta Power is Provisional unless a dated metagame sample is supplied Master Duel has no side deck in this export, so D12 is Provisional
