Sacred Beast Deck #398310 — Yu-Gi-Oh! Master Duel

Deck — Deck Power Evaluation

Final Contextual Deck Power: 30/100 (±8 · Confidence: Low)

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

Legality

Main 53 / Extra 15 / Side 0 — status under the rules at evaluation time: Illegal. 3 violation(s).

Identity & game plan

• Win condition: Yubel Extra Deck bosses (Raviel, Chaos Angel, Unchained Abomination, Underworld Goddess) on a board the Yubel engine has already cleared of interaction; Yubel Fusion/Link pressure through Phantom of Yubel and Unchained Link monsters
• Turn 1 (going first): Open on a Yubel starter or searcher (Nightmare Throne, Opening of the Spirit Gates, Dark Beckoning Beast) and protect it with Ash Blossom, Effect Veiler and Maxx C before committing to a boss summon
• Turn 2 (going second): Use hand traps (Ash Blossom, Effect Veiler, Infinite Impermanence, Skull Meister, Nibiru) to break the opponent's first combo, then rebuild the Yubel line from the GY and banish zone
• Recovery: Spirit of Yubel and Samsara D Lotus recycle Yubel monsters from the GY, while Mature Chronicle and Nightmare Throne rebuild card advantage
• After siding: Not applicable: the export contains no side deck, so no post-side plan can be assessed

Why it scores here

This list is a Yubel engine with a Sacred Beast skin: only 7 of 53 main-deck cards carry the exact archetype name, and the Yubel-named starters (Yubel, Terror Incarnate, The Ultimate Nightmare, The Loving Defender) are the real engine. Searchers are dense (about 87% chance of at least one in a 5-card opening hand), so the deck usually finds a starter, but the Yubel core is present in only about 52% of openings, which caps reliable T1 access. Interaction is the strongest part of the system (11 hand traps, 4 floodgates, many negation and removal effects), and the Extra Deck supplies several 3000+ ATK closers, so the score reflects the system rather than any average of individual card strength. The deck scores low overall because it is illegal in Master Duel: three copy-limit or forbidden violations (Maxx C, Called by the Grave, Apollousa) cap it into a theoretical, structural-only read, and the 53-card main deck with 19 tech cards and no side deck dilutes consistency. Popularity and archetype share played no part in the score.

Dimension scores

How the score was computed

Strategy profile: Combo. Structural ≈ 51, Going First ≈ 52, Going Second ≈ 50, Meta = provisional, Tournament Reliability ≈ 35. Modifiers: Banlist exposure (-10); No side deck (0). Final formula: Illegal cap: min(0.80*Structural + 0.20*TournamentReliability + modifiers, 30); Meta Provisional; theoretical/structural-only

Probability & combo summary

• Opening a starter: P(≥1) ≈ 0.87 · 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 searcher and starter access for the Yubel engine
• Strong interaction layer: hand traps, floodgates and negation text
• Several 3000+ ATK Extra Deck closers with recursion for rebuilding

Weaknesses

• Illegal in Master Duel: Maxx C is over its copy limit and Called by the Grave and Apollousa are Forbidden
• Low archetype purity (10.3%): the Sacred Beast name is a thin skin over a Yubel engine
• 19 tech slots and 4 floodgates dilute the main deck and cause dead draws
• No side deck, so no post-side adaptability

Critical choke points

• Yubel starter access: the Yubel-named core is only in about half of opening hands
• Forbidden and over-limit cards must be removed before the deck can be played in Master Duel

Recommended changes

Evidence & confidence

• Verified: Main-deck count 53 and Extra-deck count 15 are within the Master Duel size rules; Maxx C is run at 3 copies against a limit of 1; Called by the Grave (2) and Apollousa (1) are Forbidden and run in the deck; Card text and stats for all listed cards; Archetype spread: 7 exact-name Sacred Beast copies out of 68 total
• Inferred: Yubel core access (≈ 0.52) and searcher density (≈ 0.87) from hypergeometric estimates; Brick and dead-draw rate from tech and floodgate density; Board-breaking and interaction layering from hand-trap and negation text; Pilotability from the number of multi-step Yubel decision points
• Provisional: Meta Power and matchup fit: no dated metagame sample or tournament link; Post-side plan: no side deck in the export
• Data gaps: no combos supplied: combo floor, median and ceiling are text-only inference no tournament link: archetype meta-share and per-pilot record absent no win-rate telemetry for this deck: going-first, going-second, matchup and brick rates are Inferred or Unknown no side deck in the export: post-side adaptability cannot be scored Meta Power is Provisional until a dated metagame sample is supplied
