Jurrac Deck #767861 — Yu-Gi-Oh! OCG

Deck — Deck Power Evaluation

Final Contextual Deck Power: 30/100 (±10 · Confidence: Low)

• Primary strategy: Midrange
• Secondary strategies: Control, Toolbox
• 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: Dinosaur board pressure through Jurrac and Dinomorphia Synchro/Fusion monsters (Jurrac Meteor, Jurrac Astero, Dinomorphia Kentregina, Dinomorphia Rexterm) once a Dinosaur board is established; Ultimate Conductor Tyranno (3500 ATK) as a main-deck boss, reachable by banishing 2 Dinosaurs from the GY
• Turn 1 (going first): Open a Dinosaur starter (Jurrac Megalo, Jurrac Stego, Souleating Oviraptor, Fossil Dig) and extend into Jurrac Meteor or Astero through Tuner and non-Tuner Dinosaurs; hold Droll & Lock Bird and Ash Blossom where possible
• Turn 2 (going second): Use hand traps (Ash Blossom, Ghost Belle, Droll & Lock Bird) to interrupt the opponent's first engine, then rebuild a Dinosaur board from the GY and deck
• Recovery: Revive from the GY via Jurrac Aeolo, Babycerasaurus, Petiteranodon, and Miscellaneousaurus banish effects, then re-enter Synchro or Fusion
• After siding: No Side Deck is registered; no post-side plan can be evaluated

Why it scores here

This OCG Jurrac list reliably opens a Dinosaur starter about 82% of the time across its 11 archetype-core copies (hypergeometric, Inferred), with 3-copy starters at roughly 34% in a 5-card opening. Its seven hand traps and Droll & Lock Bird give it a real going-second interaction plan, scored under the Going-Second dimension. Floor, median and ceiling are not measured because no recorded boards exist, so D3 and D4 are text-only estimates. The deck is Illegal, because Ash Blossom & Joyous Spring runs 3 copies against a Semi-Limited limit of 2; under the rubric's Illegal rule this is a theoretical, structural-only score, and the normal Final formula is withheld. The score is not an average of card scores and does not reward popularity: usage stats show the deck as a real archetype build, but they earned no points.

Dimension scores

How the score was computed

Strategy profile: Midrange. Structural ≈ 59, Going First ≈ 55, Going Second ≈ 62, Meta = provisional, Tournament Reliability ≈ 55. Modifiers: banlist exposure (-4); no Side Deck (-3). Final formula: Illegal cap: normal formula 0.80*59 + 0.20*55 - 7 = 51 is withheld; theoretical/structural-only score capped at 30

Probability & combo summary

• Opening a starter: P(≥1) ≈ 0.82 · 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

• Dense archetype core (11 copies of Jurrac and Dinomorphia starters) with about 82% opening access
• Seven hand traps plus Droll & Lock Bird give strong going-second interaction
• Extra Deck covers Synchro, Fusion and XYZ options with high-ATK closers

Weaknesses

• Illegal: Ash Blossom & Joyous Spring is over its Semi-Limited copy limit
• No Side Deck, so no best-of-3 adaptation
• Off-archetype copies (36 of 40 main are not exact-name Jurrac) dilute engine coherence
• Swordsoul Synchro in the Extra Deck is off-theme

Critical choke points

• Ash Blossom & Joyous Spring copy count: the list is not legal until one copy is removed
• Three-copy starters (Megalo, Stego, Oviraptor) depend on early Dinosaur draws

Recommended changes

Evidence & confidence

• Verified: Main 40 / Extra 15 / Side 0 counts (within size rules); Ash Blossom & Joyous Spring: 3 copies vs legal 2 (Semi-Limited) — illegal; Droll & Lock Bird and Miscellaneousaurus: Limited, 1 copy each (legal); Copy histogram sums to 40 main and 15 extra
• Observed: Archetype usage stats show Jurrac as a real, recurring build (21 stat rows)
• Inferred: Opening access ≈ 0.82 for the archetype core and ≈ 0.34 for 3-copy starters; Going-second hand trap access ≈ 0.71; Structural score ≈ 59 from the Midrange profile
• Provisional: Meta Power (no dated metagame sample); Matchup and format fit (no tournament link)
• Data gaps: Illegal copy-limit violation on Ash Blossom & Joyous Spring (3 copies vs 2) No combos supplied: floor, median and ceiling are text-only inference No tournament link: archetype meta-share and per-pilot match record are absent No win-rate telemetry exists in YGOVN; all brick, starter and matchup rates are Inferred Meta Power is Provisional unless a dated metagame sample is supplied usage statistics marks Jurrac Meteor and Jurrac Astero in this deck=false, but cards[] lists 3 copies of each; core-card presence (25%) is therefore unreliable and was not used for scoring Deck title is null
