Forbidden Deck #574682 — Yu-Gi-Oh! Master Duel

Deck — Deck Power Evaluation

Final Contextual Deck Power: 35/100 (±8 · Confidence: Low)

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

Legality

Main 40 / Extra 15 / Side 0 — status: Illegal. 1 violation(s).

Identity & game plan

• Win condition: Link/Xyz boss (Dingirsu, Enlilgirsu, Avramax, ZEUS, TY-PHON) built from Orcust Link monsters, backed by Orcustrated recursion; Hand-trap attrition: Ash Blossom, Ghost Belle, Infinite Impermanence and Droll punish the opponent's first real plays
• Turn 1 (going first): Open Orcust Link or Orcust monster, search or recurse via Orcustrated Return / Cymbal Skeleton / Harp Horror into a Link Summon of Galatea or Longirsu, then use Girsu or Knightmare to reach an Extra Deck boss
• Turn 2 (going second): Hold 2-3 hand traps (Ash, Ghost Belle, Impermanence) to answer the opponent's first combo, then rebuild the board with a Link Summon from the Orcust chain
• Recovery: Orcust monsters and World Legacy cards in the GY re-enter through Orcust Cymbal Skeleton, Harp Horror and Galatea-I; Orcustrated Babel recovers spells
• After siding: Not applicable: Master Duel has no side deck in this list (side_count 0), so no post-side plan exists

Why it scores here

The deck's Orcust engine is reasonably consistent: 9 copies of the core Orcust set give a hypergeometric chance of at least one core card in the opening five of about 0.74 (Inferred), and several recursion paths (Cymbal Skeleton, Harp Horror, Orcustrated Return, Galatea-I) keep the engine moving. Interaction is the strongest part of the system, with 12 hand traps and about 14 negation-text cards, which lifts going-second strength (about 0.90 chance of at least one hand trap in a six-card hand, Inferred). Conversion to a Link or Xyz boss is plausible but unverified because no recorded boards exist, so combo ceiling and median are text-based estimates only. The list is capped by an illegal copy count of Droll & Lock Bird (3 vs 2 allowed) and by three Limited cards, so the score is theoretical and structural only. Popularity and Orcust usage stats were not counted as power, and no card scores were averaged into the deck score.

Dimension scores

How the score was computed

Strategy profile: Combo. Structural ≈ 53.6, Going First ≈ 48, Going Second ≈ 58, Meta = provisional, Tournament Reliability ≈ 45. Modifiers: banlist_exposure (-3); illegal_copy_limit_cap (-14). Final formula: Illegal cap applied: unrestricted formula 0.80*Structural(53.6) + 0.20*TournamentReliability(45) + modifiers(-3) = about 49; capped to 35 because the list breaks the Master Duel copy limit. Meta Power provisional (null).

Probability & combo summary

• Opening a starter: P(≥1) ≈ 0.74 · 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

• Dense interaction: 12 hand traps plus negation and removal text across the list
• Multiple Orcust recursion routes that keep the engine alive after disruption
• Strong Extra Deck bosses at 2600-3000 ATK

Weaknesses

• Droll & Lock Bird copy limit broken (3 vs 2), making the list illegal in Master Duel
• Three Limited cards reduce consistency and make the list less accessible
• No side deck and no recorded boards, so adaptability and combo ceiling are unverified

Critical choke points

• Link Summon of an Orcust Link monster is required for most lines; losing it removes most boss access
• Limited Foolish Burial and Card Destruction are single copies, so their loss leaves no backup

Recommended changes

Evidence & confidence

• Verified: Illegal status: Droll & Lock Bird 3 copies vs legal 2 (Semi-Limited); Limited status of Card Destruction, Foolish Burial and Foolish Burial Goods; Main 40 / Extra 15 / Side 0 composition; Extra Deck link 11 and xyz 4 breakdown
• Inferred: Core Orcust opening-hand probability about 0.74; Hand-trap going-second probability about 0.90; Engine route redundancy and interaction quality from card text
• Provisional: Meta Power (no dated metagame sample); Matchup and format fit (no tournament data)
• Data gaps: No combos supplied; combo floor, median and ceiling are text-only inference No tournament link; archetype meta-share and pilot match record absent No win-rate telemetry; going-first and going-second, matchup and brick rates are Inferred or Unknown Meta Power provisional without a dated metagame sample
