Jurrac Deck #774317 — Yu-Gi-Oh! Master Duel

Deck — Deck Power Evaluation

Final Contextual Deck Power: 57/100 (±6 · Confidence: Medium)

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

Legality

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

Identity & game plan

• Win condition: Synchro Summon a large Dinosaur (Jurrac Meteor, Jurrac Astero, GMX - ALLOS, Ultimate Conductor Tyranno) off Dinosaur-based starters and tuners; Fusion/Link/Xyz finishers (Evolved Daneen, S:P Little Knight, Evolzar Dolkka) when Synchro lines are blocked
• Turn 1 (going first): Open Jurrac Megalo, Jurrac Stego, Souleating Oviraptor or Fossil Dig (about 0.85 chance of at least one in the opening 5, Inferred), extend into a Jurrac Synchro with Megalo/Aeolo as tuners
• Turn 2 (going second): Hold Ash Blossom and Dominus Impulse for the opponent's first Special Summon or search, then extend into Jurrac Astero's negate-and-destroy effect as the second-turn board
• Recovery: Recur Dinosaurs from the GY through Jurrac Aeolo's Tribute effect and Tyranno's banish cost, and refill with Mulcharmy draw effects
• After siding: None: Master Duel has no side deck in this list (Side Deck size 0), so there is no post-side adjustment

Why it scores here

The deck reliably opens a Dinosaur starter (Megalo, Stego, Oviraptor, Fossil Dig: 12 copies, about 0.85 chance of at least one in the opening 5, Inferred) and converts it into Synchro pressure through Meteor and Astero, both run three copies. Its interaction (Ash Blossom and Dominus Impulse at three copies each, plus Astero's negate) keeps the line alive through common disruption and also covers the going-second turn. Its recovery comes from Aeolo's GY revival and Mulcharmy's draw effects, not from a single card. Score is driven by consistency, median output and interaction across the whole system; it is not an average of the individual card scores. Archetype popularity earned no points: usage data only shows the list is a real, accessible build, and there is no tournament or win-rate data. The lack of recorded boards and of a side deck caps the score, and Meta Power is left provisional.

Dimension scores

How the score was computed

Strategy profile: Combo. Structural ≈ 60.6, Going First ≈ 62, Going Second ≈ 62, Meta = provisional, Tournament Reliability ≈ 52. Modifiers: archetype purity (-2). Final formula: 0.80*Structural + 0.20*TournamentReliability + ContextModifiers (Meta provisional, no dated metagame sample): 0.80*60.6 + 0.20*52 - 2 = 56.9, rounded to 57

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

• Three-copy starters and Synchro finishers (Meteor, Astero) give a consistent Dinosaur engine
• Layered interaction: Ash Blossom and Dominus Impulse at 3 copies each, plus Astero's negate
• Strong high-ATK finishers with several Extra-Deck routes

Weaknesses

• No side deck, so no post-side adjustment
• Low exact-archetype purity (32.7%) and 19 distinct main cards dilute consistency
• No recorded boards, tournament data or win rates to verify the ceiling or the median

Critical choke points

• Dinosaur starters: Megalo, Stego, Oviraptor and Fossil Dig are the entry to every Synchro line
• Synchro Summon of Meteor or Astero depends on a Tuner plus Dinosaur materials, so a single disruption can stall the turn

Recommended changes

Evidence & confidence

• Verified: Main 40, Extra 15, legal under the Master Duel size rules; no banned or limited cards; Copy counts and archetype purity (32.7%) from the export; Usage data shows the core archetype cards are standard for this build
• Inferred: P(at least one starter in opening 5) ≈ 0.85 from hypergeometric draw odds; Hand-trap, negation and removal reads from card text; Floor, median and ceiling read from card text because no boards were recorded
• Provisional: Meta Power: no dated metagame sample; Matchup fit: no tournament or win-rate data
• 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 for going-first, going-second, matchup or brick rates Meta Power is provisional without a dated metagame sample deck has no side cards, so D12 cannot be measured from data
