Yubel Deck #768061 — Yu-Gi-Oh! OCG

Deck — Deck Power Evaluation

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

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

Legality

Main 42 / Extra 15 / Side 0 — status: Illegal. 4 violation(s).

Identity & game plan

• Win condition: Yubel Special Summon chain (Yubel - Terror Incarnate into Yubel - The Ultimate Nightmare) and Link/Fusion boards from Fiendsmith and Unchained pieces (text read, Inferred); Fiendsmith's Lacrima and Fiendsmith's Desirae endboard with Link-backed negation (text read, Inferred)
• Turn 1 (going first): Open a Yubel starter or Samsara Lotus and Nightmare Throne, search a Yubel or Fiendsmith piece, then Link or Fusion into a boss (Inferred)
• Turn 2 (going second): Hold Ash Blossom, Infinite Impermanence or Ghost Belle to stop the opponent's first summon, then rebuild through Fiendsmith's Tract or Spirit of Yubel (Inferred)
• Recovery: Recursion through Spirit of Yubel, Gruesome Grave Squirmer, Mulcharmy Fuwalos and Lacrima from the GY (text read, Inferred)
• After siding: Not evaluable: side_count is 0, so there is no post-side plan (Verified)

Why it scores here

The deck reliably opens a Yubel or Fiendsmith engine: P(at least one archetype-core card in a 5-card opening hand) is about 0.88 across 14 core copies, and 15 searchers plus Nightmare Throne give good resource access (Inferred). Its interaction is layered, with 8 hand traps, roughly 8 negation-text cards and 14 removal-text cards, and P(at least one hand trap in a going-second 6-card hand) is about 0.74 (Inferred). Its closing power comes from text-described bosses such as Yubel - The Ultimate Nightmare, Fiendsmith's Desirae and the Unchained Link monsters, while floor and median output are unmeasured because no combo boards exist. The score comes from consistency, interaction and resilience on the system, not from Yubel being a popular archetype (usage share confirms the list is real, not that it is strong), and not from averaging card scores. The deck is Illegal (four copy-limit violations and no side deck), so the score is capped at 30 and the evaluation is theoretical and structural only.

Dimension scores

How the score was computed

Strategy profile: Midrange profile only; Combo secondary not blended because no combo evidence exists. Structural ≈ 61, Going First ≈ 62, Going Second ≈ 55, Meta = provisional, Tournament Reliability ≈ 50. Modifiers: Banlist exposure (-6); No side deck (-3). Final formula: Illegal cap: min(0.80*Structural(61) + 0.20*TournamentReliability(50) + Modifiers(-9), 30) = 30; theoretical/structural only, Meta Power provisional/null

Probability & combo summary

• Opening a starter: P(≥1) ≈ 0.88 · 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: 8 hand traps, 8 negation-text cards and 14 removal-text cards
• High card economy from 15 searchers and Nightmare Throne
• Full Extra Deck with Link and Fusion coverage of the core engines
• Multiple GY recursion routes for recovery

Weaknesses

• Illegal copy counts on four cards
• Three engine sub-archetypes (Yubel, Fiendsmith, Unchained) with low purity (8.8%)
• No side deck
• No recorded combo boards, so the floor and median are unmeasured

Critical choke points

• Yubel summon chain: Yubel - Terror Incarnate must be live to reach Yubel - The Ultimate Nightmare
• Fiendsmith pieces: Engraver and Tract are the only routes to Desirae and Lacrima, and both are over the copy limit

Recommended changes

Evidence & confidence

• Verified: Legality: Illegal, four copy-limit violations; Main 42, Extra 15, Side 0 against size rules 40-60, 0-15, 0-15; Extra Deck breakdown: 10 Link and 5 Fusion; Archetype purity 8.8%; 52 off-archetype copies
• Observed: Usage statistics: 11 core cards listed, 7 present (63.6%)
• Inferred: Starter and hand-trap hypergeometric estimates (0.8845 and 0.7436); Interaction and recovery reads from card text; Going-first and going-second power estimates
• Provisional: Meta Power (null); Matchup and format fit (D13); Median and floor output (D4)
• Data gaps: No combos supplied: 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, going-second, matchup and brick rates are Inferred or Unknown Meta Power is provisional without a dated metagame sample No side deck: post-side adaptability cannot be measured Deck title is null in the export
