Jurrac Deck #750276 — Yu-Gi-Oh! Master Duel

Deck — Deck Power Evaluation

Final Contextual Deck Power: 55/100 (±8 · Confidence: Medium)

• Primary strategy: Combo
• Secondary strategies: Midrange
• Format: master-duel

Legality

Main 40 / Extra 15 / Side 0 — status: Legal.

Identity & game plan

• Win condition: Extra-Deck boss threats: Ultimate Conductor Tyranno (3500 ATK), GMX - COMPREX (3700 ATK), GMX - ALLOS, Jurrac Meteor (destroy-all on Synchro Summon); Jurrac Astero negation-based tempo and Evolzar Xyz negations on the opponent's summons and activations
• Turn 1 (going first): Inferred from text: Megalo, Stego, Oviraptor and Fossil Dig/Aeolo chain into a Level 8+ or Level 10 Extra-Deck summon; hand-start odds depend on a searcher (about 0.85 for at least one in 5 cards)
• Turn 2 (going second): Inferred from text: Ash Blossom & Joyous Spring (3 copies) on the first opposing summon or effect, then recover into Extra-Deck boss summons
• Recovery: Graveyard recursion through Stego, Oviraptor, Aeolo and Tyranno's banish-2-Dinosaurs cost; Megalo and Fuwalos draw to rebuild hand
• After siding: None: the deck runs 0 side-deck cards

Why it scores here

The deck reliably opens into a Dinosaur engine: P(at least one of its 12 searcher-text cards in a 5-card opening hand) is about 0.85, so the starting plan is usually present even though each 3-copy starter alone is only about 0.34 likely. Conversion is strong on the system: Extra-Deck bosses (Tyranno 3500, COMPREX 3700, ALLOS 3000) and board-wipe/negation options (Jurrac Meteor, Astero, Evolzar) give a high ceiling, but no recorded boards exist, so the median is an inference. Interaction is concentrated in three Ash Blossom copies and Extra-Deck negations that carry material costs, and Mulcharmy/Sorcerer cards are conditional, which lowers brick management. The score comes from consistency, ceiling, and interaction assessed on the whole list; it does not come from Jurrac being a popular archetype, and it does not average card scores. Meta is provisional and the side deck is empty, so the Final score is held near the middle of the range.

Dimension scores

How the score was computed

Strategy profile: Combo. Structural ≈ 60.1, Going First ≈ 57, Going Second ≈ 58, Meta = provisional, Tournament Reliability ≈ 52. Modifiers: archetype and engine fragmentation (-3). Final formula: 0.80*Structural + 0.20*TournamentReliability + ContextModifiers (Meta provisional, no dated sample)

Probability & combo summary

• Opening a starter: P(≥1) ≈ 0.85 · key two-card combo ≈ — · full-brick estimate ≈ 0.15 (all Inferred)
• Combo output: best PowerIndex —, median —, board-per-starter —
• Turn order: 0 going-first lines vs 0 going-second lines

Strengths

• Legal under BanMasterDuel with no restricted cards and sizes 40/15/0 within the Master Duel limits (Verified)
• Searcher density: 12 searcher-text cards give about 0.85 odds of at least one in the opening 5 (Inferred)
• Extra-Deck boss pool with verified high ATK and several negation or board-wipe options (Verified text and stats)
• Three Ash Blossom & Joyous Spring provide a going-second hand-trap answer (Verified text)

Weaknesses

• Low archetype purity: 29.1% exact-name, with 6 related sub-archetypes mixed in (Verified)
• Four Mulcharmy cards require an empty field, which conflicts with a board-building Jurrac plan (Verified text, Inferred conflict)
• Only one hand-trap card (Ash x3); P(>=1 in going-second 6) is about 0.39 (Inferred)
• No side deck, so there is no post-side adaptation (Verified)
• No recorded boards, so the median and floor are unmeasured (Verified gap)

Critical choke points

• Level 4 Dinosaur supply (Stego 3, Miscellaneousaurus 3, Oviraptor 3, Kaitoptera 1) feeds Evolzar Xyz and Astero/Meteor material (Inferred)
• A single hand-trap suite (Ash x3) is the only fast interaction for going second (Inferred)

Evidence & confidence

• Verified: Legal under BanMasterDuel, sizes 40/15/0, no restricted cards; Copy histogram 9 single, 2 double, 9 triple; Extra-Deck breakdown 8 Synchro, 5 Fusion, 2 Xyz; Boss ATK values: Tyranno 3500, COMPREX 3700, ALLOS 3000, Meteor 2800; Exact-name purity 29.1%; archetype spread as listed
• Observed: One guide exists for the Jurrac archetype (guide_id 1185); its snippet references Jurrac Meteor's theme
• Inferred: Opening-hand consistency figures from the hypergeometric draw table; Combo ceiling and interaction reads from card text, not recorded boards; Structural score 60.1 and final 55 from the Combo profile with a -3 fragmentation modifier
• Provisional: Meta Power (null) and matchup/format fit (D13 at 50)
• 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 win-rate telemetry (going-first/second, matchup, brick/starter rates): those are Inferred or Unknown Meta Power is Provisional unless a dated metagame sample is supplied usage_statistics lists 25 core cards at 100% inclusion, only 5 present; treated as low-signal deck title is null
