Orcust Deck #751921 — Yu-Gi-Oh! Master Duel

Deck — Deck Power Evaluation

Final Contextual Deck Power: 55/100 (±8 · Confidence: Medium)

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

Legality

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

Identity & game plan

• Win condition: Link and Xyz boards of 2500+ ATK (Orcustrion 3000, Arc Rebellion Xyz Dragon 3000, Enlilgirsu 2600, Dingirsu 2600, Adreus 2600) built from Orcust and Phantom Knights bodies; Recursion-driven grind: Phantom Knights and Orcust monsters revived from the GY through banish-cost effects, feeding repeated Link and Xyz summons
• Turn 1 (going first): Open a starter (Girsu, Phantom Knights searchers, Orcust Knightmare) and use Phantom Knights/Orcust searches to reach two bodies for a Link or Xyz summon, keeping Fog Blade or Orcust Crescendo up as interaction
• Turn 2 (going second): Rely on the board for interaction: Fog Blade and Orcust Crescendo are conditional, and the deck has no hand traps, so it must already have a live board to answer the opponent's setup
• Recovery: Banish-cost GY revivals (Raider's Wing, Harp Horror, Cymbal Skeleton, Brass Bombard, Galatea-I) and searchers (Shade Brigandine, Mist Claws, Cloven Helm, Silent Boots) rebuild bodies after the opening is disrupted
• After siding: Not applicable: side deck is 0 cards in this list, so there is no evidence-backed post-side plan

Why it scores here

The deck reliably opens a starter in its hand: the 14 Orcust-named copies have a roughly 0.90 probability of at least one in a 5-card opening hand (proxy, Inferred), and the 14 searcher-text cards and Phantom Knights revivals keep the engine re-fuelling after it is hit. Its pressure comes from a set of 2500+ ATK Link and Xyz bosses, and its interaction is a layered but conditional set (Fog Blade, Orcust Crescendo, Steelswarm Roach, Arc Rebellion, Adreus) rather than hand traps. The score is held down by what is missing: there are no hand traps, and several archetype-standard disruption staples (Ash Blossom, Maxx C, Droll & Lock Bird) are absent, which weakens going-second play. Popularity and archetype usage did not earn points, and the score was not produced by averaging individual card scores; no recorded boards exist, so the combo ceiling and median are text-based Inferred reads that pull confidence to Medium.

Dimension scores

How the score was computed

Strategy profile: Combo. Structural ≈ 61.4, Going First ≈ 66, Going Second ≈ 52, Meta = provisional, Tournament Reliability ≈ 55. Modifiers: Engine conflict across sub-archetypes (-2); Missing archetype-standard interaction (-3). Final formula: 0.80*Structural + 0.20*TournamentReliability + ContextModifiers (Meta provisional); 0.80*61.4 + 0.20*55 = 60.1, then modifiers -5 = 55

Probability & combo summary

• Opening a starter: P(≥1) ≈ 0.9 · key two-card combo ≈ — · full-brick estimate ≈ 0.1 (all Inferred)
• Combo output: best PowerIndex —, median —, board-per-starter —
• Turn order: 0 going-first lines vs 0 going-second lines

Strengths

• Legal list with 40 Main and 15 Extra cards, with restricted cards (Foolish Burial, Reinforcement of the Army) at 1 copy each (Verified)
• Strong closing bosses: Orcustrion, Arc Rebellion Xyz Dragon, Enlilgirsu, Dingirsu and Adreus all at 2500+ ATK (Verified stats)
• Layered conditional interaction: Fog Blade x3, Orcust Crescendo x2, Steelswarm Roach and Adreus (Inferred from text)
• Many GY revival and searcher routes give recovery after the opening is hit (Inferred)

Weaknesses

• No hand traps and no floodgates, so the deck has no cheap answer to going-second setups (Verified composition)
• Archetype core coverage is 9 to 13 of 25 cards (see data gaps); Ash Blossom, Maxx C and Droll & Lock Bird are missing (Verified usage stats)
• Engine split between Phantom Knights (23) and Orcust (14) raises the risk of cards that don't combo with each other (Verified composition, Inferred impact)
• Empty side deck: no post-side plan at all (Verified)

Critical choke points

• Orcust Link on the field is required for Orcust Crescendo to negate, so interaction depends on the Link engine having already resolved (Inferred from card text)
• A starter missing from the opening hand (roughly 10% per the proxy) leaves the engine with no line to start (Inferred)

Recommended changes

Evidence & confidence

• Verified: Legal in master-duel: 40 Main, 15 Extra, 0 Side with restricted copies at 1 each; Composition: 0 hand traps, 0 floodgates, 14 searcher-text, 7 negation-text, 29 removal-text (regex scaffold); Archetype purity 25.5% exact, Phantom Knights 23 copies; Usage stats list Maxx C, Ash Blossom, Droll & Lock Bird and Knightmare Phoenix as core and absent
• Inferred: Starter probability ≈ 0.90 and brick estimate ≈ 0.10 from hypergeometric proxy; Combo ceiling and median from text only, since no recorded boards exist; Interaction quality from card text; Going-second weakness from the absence of hand traps
• Provisional: Meta power and matchup fit (no dated metagame sample or tournament link)
• 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 for this deck Meta Power is Provisional unless a dated metagame sample is supplied usage_statistics in_this_deck flags conflict with the card list: Galatea-I (48835607), Dingirsu (93854893), Enlilgirsu (74820316) and Longirsu (76145142) appear in the Extra Deck list but are marked in_this_deck:false, so core_cards_present 9 of 25 (36%) likely undercounts; the real figure may be 13 of 25 (52%) side deck is empty, so no best-of-3 side plan can be evaluated
