Jurrac Deck #772936 — Yu-Gi-Oh! OCG

Deck — Deck Power Evaluation

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

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

Legality

Main 55 / Extra 15 / Side 0 — status under the rules at evaluation time: Illegal. 3 violation(s).

Identity & game plan

• Win condition: Dinosaur Fusion/Synchro/Link extra-deck boards (GMX Fusion and Jurrac Synchro) built from the GMX and Jurrac engine, closed by GMX-VELOX/ALLOS/COMPREX and Evolzar/Jurrac extra-deck threats; Ultimate Conductor Tyranno and Dogoran as high-ATK single-card beatsticks
• Turn 1 (going first): Normal Summon Returned Dino Daneen or Jurrac Megalo, use GMX Researcher Selande or Fossil Dig to find the GMX/Dinosaur core, then build a Fusion or Synchro board; hold Ash Blossom, Infinite Impermanence, and Evenly Matched for the opponent's first interaction
• Turn 2 (going second): Use the six-card hand to find a hand trap (Ash, Ghost Ogre, Nibiru, Droll) on the opponent's first summon or activation, then convert into the same GMX/Dinosaur extra-deck route
• Recovery: Recover through GMX Chairman Kimridge and GMX Applied Experiment #55 recursion, Returned Dino Daneen search, and Mulcharmy Fuwalos or Purulia draw effects
• After siding: Not evaluable: the deck runs no side deck (side_count 0), so no post-side plan exists

Why it scores here

This list is illegal in OCG: three copies of Ash Blossom & Joyous Spring exceed its Semi-Limited maximum of two, so it does not receive a normal Final Contextual score and is capped at 30, with the evaluation limited to structural reasoning. Structurally, the deck opens its engine reasonably often: the 12-copy archetype core has about a 72% chance of at least one card in a 5-card opening hand (Inferred), and the 16 hand traps give about 89% at least one going second. Its weaknesses are coherence and bricks: only about 7% of the main deck uses the exact Jurrac name, with 65 off-archetype copies spread across GMX, Mulcharmy, Evolzar, Kaiju, Forbidden, Solemn and others, and the proxy brick rate is about 28%. There is no combo evidence, no tournament link and no side deck, so the combo, floor and side-deck dimensions are text-only inferences. The score was built from consistency, interaction and resilience on the system; popularity of the Jurrac archetype did not earn points, and no card scores were averaged.

Dimension scores

How the score was computed

Strategy profile: Midrange primary, Stun secondary, ratio not applied: the Midrange profile is used unchanged. Structural ≈ 49, Going First ≈ 45, Going Second ≈ 52, Meta = provisional, Tournament Reliability ≈ 40. Modifiers: banlist_exposure (-4); engine_conflicts (-4). Final formula: Structural 49 and TR 40 give 0.80*49 + 0.20*40 = 47.2 before modifiers; modifiers total -8 gives 39; the Illegal legality cap sets the final to 30 (Meta provisional)

Probability & combo summary

• Opening a starter: P(≥1) ≈ 0.72 · key two-card combo ≈ — · full-brick estimate ≈ 0.28 (all Inferred)
• Combo output: best PowerIndex —, median —, board-per-starter —
• Turn order: 0 going-first lines vs 0 going-second lines

Strengths

• Dense hand-trap suite (16 cards) with two-way coverage of summons, activations and set traps
• Searchers and recursion (Fossil Dig, Kimridge, Daneen, Experiment #55) help the engine find pieces
• Extra Deck covers four summoning methods with multiple boss threats

Weaknesses

• Illegal in OCG: Ash Blossom at 3 copies exceeds the Semi-Limited limit of 2
• Low archetype purity (7.1%) and many off-archetype copies weaken engine coherence
• No side deck, so no post-side adaptation
• Seven Limited cards make the list fragile to banlist and availability changes

Critical choke points

• Legal fix to the Ash Blossom count is required before any normal score applies
• Several engines depend on one Dinosaur or GMX monster being live, so a single removal or negation can stop the Extra Deck route
• Limited cards such as Solemn Judgment and Pot of Prosperity are single-copy dependencies

Recommended changes

Evidence & confidence

• Verified: Legality: Illegal, Ash Blossom 3 copies vs OCG limit 2; Composition: 55 main, 15 extra, 0 side; purity 7.1%; 65 off-archetype copies; Banlist: seven Limited cards run at their legal maximum
• Inferred: Core-group consistency 0.72 and brick proxy 0.28 from hypergeometric estimates; Interaction density from hand-trap and negation text; Extra-Deck route ceilings from card text
• Provisional: Meta Power is null; no dated metagame sample; Matchup fit (D13) rests on archetype context only
• Data gaps: Illegal list: Final Contextual score capped at 30; structural reading only No combos supplied (combos_evidence has 0 boards): floor, median and ceiling are text-only inference No tournament link: archetype meta-share and per-pilot record absent No side deck: post-side and D12 are not measurable Usage statistics conflict with the deck list: Jurrac Astero, Jurrac Meteor and Promethean Princess are in the deck's Extra Deck but usage marks them in_this_deck=false Deck title is null Meta Power is Provisional unless a dated metagame sample is supplied
