Yubel Deck #751968 — Yu-Gi-Oh! Master Duel

Deck — Deck Power Evaluation

Final Contextual Deck Power: 63/100 (±6 · Confidence: Medium)

• Primary strategy: Midrange
• Secondary strategies: Control, Toolbox
• Format: master-duel

Legality

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

Identity & game plan

• Win condition: Yubel boss monsters and high-ATK Extra Deck closers (Chaos Angel, Varudras, D/D/D Wave High King Caesar, A Bao A Qu) converting a board the deck has already cleared with hand traps and Yubel removal; Phantom of Yubel and Aerial Eater recurring from the GY through Spirit of Yubel and Fiendsmith or Unchained revival effects
• Turn 1 (going first): Opening of the Spirit Gates or Dark Beckoning Beast searches a Yubel-line card or a Fiendsmith/Unchained enabler, Samsara D Lotus or Nightmare Throne adds the Yubel core, and the turn ends with a Yubel or Spirit of Yubel board backed by Ash Blossom and Droll
• Turn 2 (going second): Hold Ash Blossom, Droll & Lock Bird, and Maxx C to interrupt the opponent's summon or search chain, then rebuild through Spirit of Yubel and the Yubel boss from the GY or hand
• Recovery: Samsara D Lotus, Spirit of Yubel recursion from GY/banish, and Fiendsmith Engraver or Unchained Soul of Sharvara re-establish a Fiend board after a clean removal or negation
• After siding: Not applicable: Master Duel has no side deck in this export, so there is no post-side plan to evaluate

Why it scores here

The deck reliably opens a Yubel-line starter: the core archetype group is almost certainly present in an opening hand (about 0.999 by the proxy estimate), and searcher-text cards appear in roughly 0.99 of opening hands, so the engine comes online by turn 1 or 2 in most games. Its interaction stack is the strongest part of the system: 6 hand traps (3 Ash Blossom, 2 Droll & Lock Bird, 1 Maxx C) plus Gruesome Grave Squirmer, Crossout Designator, and Nightmare Throne give layered answers on both turns. Recovery is credible through Spirit of Yubel and Samsara D Lotus recursion, and the Extra Deck supplies closers well above the usual threshold (Chaos Angel 3500 ATK, Varudras 3000 ATK, D/D/D Wave High King Caesar 2800 ATK). The score is not inflated by the popularity of the Yubel name: the list runs only about 7% exact-name Yubel cards and mixes Fiendsmith, Unchained, Sacred Beast, Mulcharmy and D/D/D pieces, which costs consistency and is penalised. No combo boards were supplied, so the ceiling and median are text-based inferences, and the usage-stat signal confirms the list is accessible but does not by itself earn points. The score was built from the system's consistency, interaction, and closing power, not from averaging card scores.

Dimension scores

How the score was computed

Strategy profile: Midrange primary with a Control secondary read from the hand-trap and removal density; the Midrange profile weights are used unchanged. Structural ≈ 68, Going First ≈ 64, Going Second ≈ 70, Meta = provisional, Tournament Reliability ≈ 62. Modifiers: Engine conflicts (-3); Banlist exposure (-1). Final formula: 0.80*Structural + 0.20*TournamentReliability (Meta provisional); 0.80*68 + 0.20*62 = 66.8, then modifiers -4 gives 62.8, rounded to 63

Probability & combo summary

• Opening a starter: P(≥1) ≈ 1 · 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

• Layered interaction: 6 hand traps plus Crossout Designator, Nightmare Throne, and Yubel removal text
• Strong Extra Deck closers reaching 2800-3500 ATK
• Redundant searcher text in about 22 cards keeps the engine accessible on turns 1 and 2

Weaknesses

• Low exact-archetype purity (about 7%) with four related sub-archetypes, so engines can conflict
• Several dead-draw cards (Piri Reis Map, Nightmare Pain, Fabled Lurrie, Maxx C) in a 40-card main
• No combo boards, win-rate telemetry, or tournament sample, so the ceiling, floor, and format fit are inferred or provisional

Critical choke points

• The Yubel boss and Spirit of Yubel: if the opponent clears the board before the Yubel line resolves, the deck relies on GY recursion
• Single-copy staples (Yubel, Yubel - Terror Incarnate, Maxx C, Crossout Designator) with no backup

Recommended changes

Evidence & confidence

• Verified: Deck is legal in Master Duel with 40 main and 15 extra cards; Restricted cards run within their copy limits (Maxx C 1, One for One 1, Crossout Designator 1, Droll & Lock Bird 2, Phantom of Yubel 2); Hand-trap, searcher, and removal role counts from curated tags and card text; Hypergeometric draw odds from the resolved main deck
• Observed: Archetype usage statistics show Yubel, Ash Blossom, Nightmare Throne, and Samsara D Lotus as core cards in the deck
• Inferred: Starter consistency, brick risk, and interaction quality are estimated from text and draw odds; Combo ceiling and median are read from card text because no recorded boards exist
• Provisional: Meta power is null with no dated metagame sample; Matchup and format fit use a neutral score with no tournament link; Side-deck adaptability is neutral because the format has no side deck in this export
• Data gaps: No combos supplied, so the combo floor, median, and ceiling are text-only inference No tournament link, so archetype meta-share and per-pilot match record are absent No win-rate telemetry (going-first/second, matchup, brick or starter rates) Meta Power is provisional unless a dated metagame sample is supplied The deck title is null in the export
