Yubel Deck #770382 — Yu-Gi-Oh! Master Duel

Deck — Deck Power Evaluation

Final Contextual Deck Power: 58/100 (±9 · Confidence: Low)

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

Legality

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

Identity & game plan

• Win condition: Special Summon a Yubel boss (Yubel, Yubel - Terror Incarnate, or Yubel - The Loving Defender Forever) and convert the board with Yubel-protected attackers and Extra Deck Link/Fusion monsters (Inferred from card text).; Extra Deck pressure from Azamina, Luce the Dusk's Dark, A Bao A Qu, and Unchained Soul links once a Fiend board is established (Inferred).
• Turn 1 (going first): Open a searcher or Fiend starter (Nightmare Throne, Opening of the Spirit Gates, Dark Beckoning Beast, Samsara D Lotus), search a Yubel-named monster, and hold Ash Blossom or Infinite Impermanence for the first opponent response (Inferred).
• Turn 2 (going second): Use the 9 hand traps (Ash Blossom, Droll & Lock Bird, Maxx C, Infinite Impermanence, Dominus Impulse) to stop the opponent's first search or Special Summon, then rebuild through Samsara D Lotus or Spirit of Yubel (Inferred).
• Recovery: Recover through Nightmare Pain, Mutiny in the Sky, Spirit of Yubel and Chaos Summoning Beast, which return or re-add Yubel-named monsters from the GY, banish or Deck (Inferred from text).
• After siding: No Side Deck is registered, so there is no post-side plan; the deck must rely on its main-deck hand traps for all matchups (Verified: side_count 0).

Why it scores here

The deck reliably opens its starters: it runs 18 searcher-text cards, three copies each of several Fiend starters, and a P(at least one searcher in a 5-card hand) of about 0.96 (Inferred). Its real plan is a single Yubel boss that is hard to recover once it is lost, so the score is capped by the one-copy Yubel starter and the lack of recorded boards. Interaction is the strongest part: nine hand traps, fifteen removal-text cards and thirteen negation-text cards give it layered answers for both going first and going second. No combo boards exist, so floor, median and ceiling are text-only inferences and the score rests on consistency and interaction of the system, not on any card's power. The deck has no Side Deck, so post-side adaptability scores very low, and popularity (archetype usage stats) only confirms the list is accessible; it did not earn points. Final score was not an average of card scores.

Dimension scores

How the score was computed

Strategy profile: Midrange. Structural ≈ 61, Going First ≈ 60, Going Second ≈ 66, Meta = provisional, Tournament Reliability ≈ 58. Modifiers: Single-copy boss starter (-2). Final formula: 0.80*Structural + 0.20*TournamentReliability + ContextModifiers (Meta provisional/null)

Probability & combo summary

• Opening a starter: P(≥1) ≈ 0.96 · 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

• Eight searcher-text starters give a high probability of an opening starter.
• Nine hand traps plus removal and negation text give layered interaction on both turns.
• Legal list with no copy-limit violations; Limited and Semi-Limited cards are run at legal counts.

Weaknesses

• No Side Deck, so no post-side adaptation at all.
• Single-copy Yubel is the only deck-defining boss; losing it limits the end-board.
• Archetype purity is low (9.1% exact name), with many generic and off-archetype cards diluting the engine.

Critical choke points

• Yubel (1 copy) being in hand or reachable by search, since the boss depends on it.
• Hand traps (9 cards) being the only defense on the going-second turn when the opponent starts with a Special Summon.

Recommended changes

Evidence & confidence

• Verified: Legal under master-duel ban list; Maxx C Limited 1, Droll & Lock Bird, Phantom of Yubel and Super Polymerization Semi-Limited 2 each.; Main 40 / Extra 15 / Side 0; composition counts and copy histogram.; Card text excerpts for Yubel, Samsara D Lotus, Ash Blossom and Nightmare Pain.
• Inferred: Midrange primary strategy and Toolbox secondary from hand-trap density and Fiend-starter structure.; P(at least one searcher in hand5) ≈ 0.96 and P(Yubel in hand5) = 0.125.; Interaction and resilience dimensions from role tags and text reads.
• Provisional: Meta Power is null and matchup fit (D13) is neutral because no dated metagame sample exists.; Going-second strength is judged from hand-trap count, not measured results.
• 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 (going-first/second, matchup, starter or brick rates). Usage-statistics in_this_deck flags conflict with the card list for Phantom of Yubel, Aerial Eater, Unchained Soul Lord of Yama and S:P Little Knight; core presence unreliable. Deck has no title (Deck.Title null) and no Side Deck.
