Jurrac Deck #773315 — Yu-Gi-Oh! OCG

Deck — Deck Power Evaluation

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

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

Legality

Main 40 / Extra 15 / Side 0 — status under the rules at evaluation time: Illegal. 1 violation(s).

Identity & game plan

• Win condition: Synchro boss (Jurrac Meteor, Jurrac Astero, Chengying) or Dinomorphia Kentregina/Rexterm pressure after a Jurrac board is established; Fusion/Xyz finishers (Kentregina 4000 ATK, Transcendosaurus Drillygnathus) when the board is cleared
• Turn 1 (going first): Open Jurrac Stego or Souleating Oviraptor, use the Stego/Oviraptor effect to reach a Synchro-capable Dinosaur board, then Jurrac Megalo or Aeolo as the second Dinosaur link
• Turn 2 (going second): Hold Ash Blossom, Ghost Belle, Droll and Dinomorphia Frenzy for the opponent's first starter, then rebuild through Megalo/Aeolo recursion into Meteor or Astero
• Recovery: Recycle Megalo and Aeolo from the GY, use Babycerasaurus and Petiteranodon when destroyed by card effect, and rebuild the Synchro board from the GY
• After siding: No side deck is registered, so no post-side plan can be evaluated

Why it scores here

The deck opens a Dinosaur board reliably: the archetype core (Jurrac Stego, Oviraptor, Megalo, Aeolo and Jurrac Volcano) has an estimated 82% chance of at least one live starter in a 5-card opening hand, and it has 8 searcher-text cards plus Fossil Dig to add to that. Conversion into a Synchro board is plausible through Meteor and Astero, which both have 3 copies, while Megalo and Aeolo recur from the GY and keep the engine going after interruption. Interaction is dense: 7 hand traps (Ash, Ghost Belle, Droll and Dinomorphia Frenzy, among others) and 25 removal-text cards give it a strong answer density for the first turns. The score is capped because the list is Illegal (3 copies of Ash Blossom against a limit of 2) and no side deck is registered; the Jurrac and Dinomorphia engines also split the deck (exact Jurrac purity 34.5%). Popularity and the archetype's usage stats were not counted as power, and no card scores were averaged into the deck score.

Dimension scores

How the score was computed

Strategy profile: 0.8 Midrange + 0.2 Stun. Structural ≈ 59, Going First ≈ 60, Going Second ≈ 56, Meta = provisional, Tournament Reliability ≈ 55. Modifiers: banlist exposure (-6); engine conflict (-4). Final formula: Pre-cap: 0.80*Structural(59.4) + 0.20*TournamentReliability(55) + modifiers(-10) = 48.5; Illegal deck capped to 30 as theoretical/structural-only (no normal Final score); Meta Power provisional/null

Probability & combo summary

• Opening a starter: P(≥1) ≈ 0.82 · key two-card combo ≈ — · full-brick estimate ≈ 0.18 (all Inferred)
• Combo output: best PowerIndex —, median —, board-per-starter —
• Turn order: 0 going-first lines vs 0 going-second lines

Strengths

• Seven hand traps plus Droll and Ash-style interaction give multiple answers to first-turn starters
• Jurrac Megalo and Aeolo recursion and Babycerasaurus or Petiteranodon revival give the deck independent continuations
• Jurrac Meteor and Astero provide two Synchro boss options with three copies each

Weaknesses

• Illegal list: 3 copies of Ash Blossom & Joyous Spring against a Semi-Limited limit of 2
• No side deck, so there is no post-side adaptability
• Two engines (Jurrac and Dinomorphia) plus one-off Saber, Swordsoul and Transcendosaurus cards reduce coherence

Critical choke points

• Jurrac Stego and Oviraptor as the only Dinosaur starters that reach the Synchro board
• Ash Blossom over the copy limit must be fixed before the deck can be played in OCG
• Megalo recursion depends on the GY holding Jurrac monsters

Recommended changes

Evidence & confidence

• Verified: Legality: Ash Blossom 3 copies against a Semi-Limited legal limit of 2 (Illegal); Main 40, Extra 15, Side 0 within OCG size rules; Hypergeometric draw probabilities from the Main Deck (archetype core 0.8195); Card text and banlist status for the 20 distinct Main and 10 distinct Extra cards
• Observed: Usage statistics: Jurrac Megalo at 85% and Miscellaneousaurus at 80% inclusion; the archetype core is 25% present in this list
• Inferred: Consistency and brick estimates from hypergeometric values and text; Interaction density and resilience from hand-trap and removal text; Going-first and going-second plans from text and starter structure; Dimension scores D1 to D11 and D14
• Provisional: Meta Power (null) and matchup fit D13 (no dated metagame sample); Side deck adaptability D12 (no side deck)
• 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 side deck registered: post-side plan cannot be evaluated No win-rate telemetry for going-first, going-second, matchup or brick rates Meta Power provisional unless a dated metagame sample is supplied Deck title is null
