Yubel Deck #771080 — Yu-Gi-Oh! OCG

Deck — Deck Power Evaluation

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

• Primary strategy: Midrange
• Secondary strategies: Toolbox, Combo
• Format: ocg

Legality

Main 40 / Extra 15 / Side 0 — status under the rules at evaluation time: Illegal. 4 violation(s).

Identity & game plan

• Win condition: Yubel and Fiendsmith boss monsters (Fiendsmith's Desirae, Yubel - The Loving Defender Forever, Unchained Abomination) converting a board built from Fiend-monster recursion and hand traps; Link-based pressure through Unchained Soul Lord of Yama and Unchained Abomination once a Yubel or Unchained line lands
• Turn 1 (going first): Open with Fiendsmith Engraver or Nightmare Throne / Opening of the Spirit Gates to search a Fiend or Yubel starter, then Normal Summon or Special Summon a Yubel line and extend into a link or fusion boss
• Turn 2 (going second): Hold Ash Blossom and Effect Veiler as hand traps against the opponent's first engine, then rebuild through Gruesome Grave Squirmer and Dark Beckoning Beast searches
• Recovery: Recurse Spirit of Yubel, Lacrima the Crimson Tears, and Unchained Soul of Sharvara from the GY, and use Nightmare Throne to add a Yubel monster when a Yubel leaves the field
• After siding: Not evaluable: the deck has no Side Deck (Side Deck size 0), so no post-side plan exists

Why it scores here

The deck is Illegal in the OCG format: four cards exceed their copy limits (Ash Blossom and Super Polymerization at 3 copies against 2 legal, Fiendsmith Engraver at 3 against 1, Fiendsmith's Tract at 2 against 1), so under the rubric it receives a capped theoretical score rather than a normal contextual score. Structurally, the list reliably reaches a starter: the archetype core is present in about 93.5% of opening 5-card hands and a searcher in about 97% (Inferred), which gives a credible T1 engine for a Midrange shell with 7 hand traps and 7 negation-text cards for interaction. Its weaknesses are a split engine (Fiendsmith, Unchained, Sacred Beast and Yubel sub-archetypes with only 5 exact-name Yubel copies, 9.1% purity), a 0-Side deck that gives no post-side plan, and no recorded boards to measure a combo ceiling or median. The score comes from consistency and interaction on the system, not from Yubel being a known archetype, and no card scores were averaged.

Dimension scores

How the score was computed

Strategy profile: Midrange. Structural ≈ 49, Going First ≈ 50, Going Second ≈ 42, Meta = provisional, Tournament Reliability ≈ 35. Modifiers: banlist exposure (-10); illegal_cap (-6). Final formula: 0.80*Structural + 0.20*TournamentReliability (Meta provisional) = 46.2, then context modifiers -10 = 36, then capped at 30 because the list is Illegal (theoretical/structural-only)

Probability & combo summary

• Opening a starter: P(≥1) ≈ 0.94 · key two-card combo ≈ — · full-brick estimate ≈ 0.06 (all Inferred)
• Combo output: best PowerIndex —, median —, board-per-starter —
• Turn order: 0 going-first lines vs 0 going-second lines

Strengths

• Core archetype reached in about 93.5% of 5-card hands (Inferred)
• Layered interaction: 7 hand traps and 7 negation-text cards (Inferred)
• Redundant recursion from the GY across Spirit of Yubel, Lacrima and Sharvara (Inferred)
• Strong boss monsters in the Extra Deck, including Unchained Abomination and Fiendsmith's Desirae (Verified stats)

Weaknesses

• Illegal copy-limit violations on four cards (Verified)
• No Side Deck, so no post-side plan (Verified)
• Split engine across Fiendsmith, Unchained, Sacred Beast and Yubel with only 9.1% exact-name purity (Verified composition)
• No recorded boards, so combo ceiling and median cannot be measured (Verified data gap)

Critical choke points

• Fiendsmith Engraver and Fiendsmith's Tract are Limited, so the Fiendsmith search chain breaks under the copy limit
• Yubel starter density depends on 1-of Yubel and Yubel - Terror Incarnate, so losing those to a single hand trap stalls the line

Recommended changes

Evidence & confidence

• Verified: Illegal status with four copy-limit violations under OCG BanList; 0-card Side Deck and 40/15 main/extra counts; Exact-name archetype purity 9.1% and 16 archetype-core copies
• Observed: Usage stats show Samsara Lotus, Yubel, Nightmare Throne and Ash Blossom as core cards in the archetype
• Inferred: Starter access about 93.5% in 5-card hands from hypergeometric estimate; Interaction layering from hand-trap and negation text counts; Consistency and brick-rate estimates from text read
• Provisional: Meta Power is null because no dated metagame sample was supplied; Matchup fit scores are provisional without tournament data
• 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 going-first, going-second, matchup or brick rates Meta Power is Provisional unless a dated metagame sample is supplied deck title is null, so the deck is identified only by its id and archetype
