Jurrac Deck #770189 — Yu-Gi-Oh! OCG

Deck — Deck Power Evaluation

Final Contextual Deck Power: 35/100 (±8 · Confidence: Low)

• Primary strategy: Midrange
• Secondary strategies: Tempo
• Format: ocg

Legality

Main 40 / Extra 15 / Side 0 — status: Illegal. 1 violation(s).

Identity & game plan

• Win condition: Jurrac Meteor and Jurrac Astero Synchro boards, with Jurrac Velphito and Ultimate Conductor Tyranno as heavy closers; Promethean Princess and Salamangreat Raging Phoenix are absent from the list, so no secondary link finisher is present; the Extra Deck is Synchro-led
• Turn 1 (going first): Turn 1 Jurrac Megalo or Stego starts a Dinosaur chain (Stego to Aeolo and Megalo recursion, Volcano and Fossil Dig for the Jurrac Synchro material), reaching a Synchro boss by turn 2 when the hand has at least one starter
• Turn 2 (going second): Open with the hand traps (Ash Blossom, Infinite Impermanence, Effect Veiler) to answer the opponent's first summon or search, then rebuild through Megalo recursion and Dinosaur Synchro summons
• Recovery: Ash, Veiler and Tyranno recursion, Aeolo and Megalo graveyard re-summons, and Xeno Meteorus or Jurrac Meteor Tuner recursion
• After siding: Not applicable: the deck has no Side Deck, so there is no post-side plan

Why it scores here

The list is a Jurrac Dinosaur shell with a Synchro Extra Deck, and its Main Deck has enough starters and recursion to open a functional plan about 78 percent of the time with a 5-card hand (archetype-core proxy). Hand traps (9 cards) and recursive Tuners give it a reasonable floor against interruption and a strong going-second posture, while Infinite Impermanence, Ash Blossom and Effect Veiler carry most of the interaction. Output is capped by the lack of recorded boards, so the combo ceiling and median are text-only inferences. The score does not come from Jurrac being a popular archetype, and no card scores were averaged. The list is illegal because it runs three copies of Ash Blossom and Joyous Spring against a Semi-Limited limit of two, so this is a theoretical, structural-only read capped at 35.

Dimension scores

How the score was computed

Strategy profile: Midrange. Structural ≈ 56, Going First ≈ 60, Going Second ≈ 62, Meta = provisional, Tournament Reliability ≈ 49. Modifiers: Banlist exposure (-4); No Side Deck (-2); Illegal list cap (-14). Final formula: Uncapped: 0.80*Structural(56) + 0.20*TournamentReliability(49) + modifiers(-6) ≈ 49; Illegal cap applied, so reported as 35 (theoretical, structural-only). Meta Power provisional.

Probability & combo summary

• Opening a starter: P(≥1) ≈ 0.78 · key two-card combo ≈ — · full-brick estimate ≈ 0.22 (all Inferred)
• Combo output: best PowerIndex —, median —, board-per-starter —
• Turn order: 0 going-first lines vs 0 going-second lines

Strengths

• Core Jurrac starters run 3 copies each, with about 78 percent 5-card access to a core card
• Nine hand traps and Ash Blossom plus Effect Veiler give strong going-second interaction
• Recursion from Megalo, Aeolo, Tyranno and Meteor supports resilience after disruption
• Synchro Extra Deck covers boss boards: Meteor, Astero, Velphito, Carnovorus and Dolkka

Weaknesses

• Illegal copy count: 3 Ash Blossom against a Semi-Limited limit of 2
• Low archetype purity (34.5 percent): 27 generic copies dilute the engine
• No Side Deck, so no post-side adaptability in best-of-3
• Four Limited cards reduce consistency if the list is legalised

Critical choke points

• Dinosaur-monster count gates Megalo's hand Special Summon and Stego's Dinosaur-count requirement
• Ash Blossom over the copy limit means the list cannot be legally played as built

Recommended changes

Evidence & confidence

• Verified: Illegal status: Ash Blossom & Joyous Spring 3 copies vs legal 2; Main 40, Extra 15, Side 0 (OCG size rules met for Main and Extra); Banlist: Miscellaneousaurus, Pot of Prosperity, S:P Little Knight and Linkuriboh are Limited; Archetype purity 34.5 percent (19 exact of 55 archetype-relevant copies)
• Inferred: Going-second hand-trap access ≈ 0.81 from hypergeometric estimate; Brick rate proxy ≈ 0.22 from core-group estimate; Interaction density from negation-text counts; Combo ceiling from card text only
• Provisional: Meta power and format fit (no dated metagame sample or tournament link)
• Data gaps: No combos supplied; floor, median and ceiling are text-only inference No tournament link; archetype meta-share and pilot record absent No win-rate telemetry; going-first, going-second, matchup and brick rates are Inferred or Unknown Meta Power provisional without a dated metagame sample
