Orcust Deck #754372 — Yu-Gi-Oh! Master Duel

Deck — Deck Power Evaluation

Final Contextual Deck Power: 58/100 (±7 · 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 Fusion boss pressure from Dingirsu, Caesar, Enlilgirsu, Snake-Eyes Doomed Dragon and Longirsu, reached through Orcust Harp Horror and Girsu special-summon chains; Mulcharmy card advantage plus hand-trap-backed grind over a long round
• Turn 1 (going first): Turn 1 Harp Horror or Girsu (Normal/Special Summon to GY-recursion and Orcust Deck-to-hand/summon lines), spend the turn building a Link or Xyz boss while holding Ash Blossom, Infinite Impermanence and Maxx C for the opponent's first interaction
• Turn 2 (going second): Keep a hand-trap-first six: Droll and Lock Bird, Ash Blossom, Infinite Impermanence, Maxx C and Ghost Belle answer the opponent's first two summons or searches, then the Orcust engine converts into a board
• Recovery: Banish Harp Horror, Cymbal Skeleton and Knightmare from the GY, Orcust Crescendo and Orcustrated Babel recursion, Foolish Burial to restock the Extra Deck route, Mulcharmy draws when the hand is empty
• After siding: No side deck is run in Master Duel; the deck has no post-side plan and adapts only through in-match hand-trap sequencing

Why it scores here

The deck scores on its system, not on its card quality or popularity. Two Orcust starters (Harp Horror and Girsu, six copies between them) give roughly a 58 percent chance of at least one in a five-card opening hand (Inferred, hypergeometric). Ten hand traps, led by Ash Blossom and Infinite Impermanence at three copies each, plus Droll and Maxx C, give an estimated 85 percent chance of at least one hand trap in a six-card going-second hand (Inferred), which carries the interaction and resilience scores. The Extra Deck is fully used (15 distinct Link, Fusion, Xyz and Extra threats), so late-game closing power is strong, but the engine is spread across Orcust, Fiendsmith, Mekk-Knight, World Legacy and Mulcharmy families with only 20 percent exact-name purity, which costs engine cohesion and pilotability. No boards were recorded and there is no meta or tournament sample, so the combo ceiling and floor are text-based Inferred reads, and Meta Power stays provisional with the final score built from Structural and Tournament Reliability only. Popularity was not credited, and card scores were not averaged.

Dimension scores

How the score was computed

Strategy profile: Midrange primary, Toolbox secondary (hand-trap-driven toolbox elements); blend ratio approximately 85/15. Structural ≈ 62, Going First ≈ 60, Going Second ≈ 66, Meta = provisional, Tournament Reliability ≈ 57. Modifiers: Engine conflicts (-3); Archetype dilution (-2); Hand-trap redundancy (2). Final formula: 0.80*Structural + 0.20*TournamentReliability + ContextModifiers (Meta provisional): 0.80*62 + 0.20*57 - 3 ≈ 58

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

• Ten hand traps and multiple negation routes give strong going-second interaction
• Full 15-slot Extra Deck with several boss options (Caesar, Dingirsu, Snake-Eyes, Enlilgirsu, Longirsu)
• Mulcharmy draw engine punishes summons and rebuilds hand
• Legal with no size or copy violations

Weaknesses

• Engine spread across four archetype families with 20 percent exact-name purity
• Summon restrictions from Harp Horror and Fiendsmith conflict on the same turn
• No side deck, so no post-side plan
• No recorded combos, so ceiling and floor are unverified

Critical choke points

• At least one of Harp Horror or Girsu in hand (about 58 percent in five cards); missing both leaves only hand traps and Mulcharmy
• Ash Blossom and Infinite Impermanence are both needed to protect a single starter vs a single hand-trap-blocking opponent

• Inferred: Hypergeometric starter and hand-trap probabilities (0.577 starter in hand of 5; 0.845 hand trap in hand of 6 going second); Going-first and going-second plans derived from card text; Engine conflict and archetype dilution assessments; Dimension scores D1–D11 and D14 (no boards supplied)
• Provisional: Meta Power (no dated metagame sample); Matchup and format fit (D13); Side deck adaptability (D12) given no side deck in Master Duel
• 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 usage_statistics in_this_deck flags mark Extra Deck cards (Galatea-I, Dingirsu, Knightmare Phoenix, Masquerena) as absent even though they are in the deck's Extra list; treated as a main-deck-only flag and not used for scoring no side deck run; post-side plan not measurable Meta Power is Provisional unless a dated metagame sample is supplied
