Jurrac Deck #558161 — Yu-Gi-Oh! Master Duel

Deck — Deck Power Evaluation

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

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

Legality

Main 40 / Extra 15 / Side 0 — status under the rules at evaluation time: Illegal. 3 violation(s).

Identity & game plan

• Win condition: Dinosaur engine (Jurrac Megalo, Jurrac Aeolo, Jurrac Stego) chains into Jurrac Meteor, Jurrac Astero and Tyranno Infinity / Promethean Princess pressure; Jurrac Meteor's board wipe followed by a Tuner recursion from the Graveyard
• Turn 1 (going first): Open with Megalo or Aeolo starter, search via Fossil Dig or Ground Xeno, then extend into a Synchro or Link using Dinosaur Graveyard recursion (Inferred; no combo boards recorded)
• Turn 2 (going second): Respond to the opponent's first summon with Droll & Lock Bird, Maxx C, Ash Blossom or Artifact Lancea, then rebuild a Dinosaur board through Jurrac Volcano and Megalo (Inferred)
• Recovery: Recover from Graveyard Dinosaurs via Souleating Oviraptor, Jurrac Aeolo tribute-summon and Megalo draw, rebuilding Extra Deck summons (Inferred)
• After siding: Not assessable: the deck runs 0 side-deck cards, so there is no post-side plan in the list

Why it scores here

The deck's score is driven by its system, not by averaging its cards. The Jurrac core is present at high rates (archetype core group about 96% to open at least one piece in a 5-card hand), so the Dinosaur engine usually comes online early, and the Graveyard recursion and searchers give it grind. Interaction is broad (11 hand-trap-type cards, Astero's negation, Evolzar's negation and Crossout Designator), which keeps the engine alive through one disruption. The Extra Deck closes the game with Meteor, Astero and link/synchro pressure. Score is held down by three things: the list is illegal (Called by the Grave is Forbidden, Droll and Maxx C exceed their limits), it has no side deck, and no combo boards or tournament evidence exist to measure its real ceiling or median. Popularity and archetype usage were not counted as power.

Dimension scores

How the score was computed

Strategy profile: Midrange. Structural ≈ 56, Going First ≈ 60, Going Second ≈ 50, Meta = provisional, Tournament Reliability ≈ 55. Modifiers: banlist exposure (-8). Final formula: Illegal list: no normal Final score. Structural 56 with banlist modifier -8 would give about 48; capped at 30 for theoretical/structural-only reading (Meta provisional, null)

Probability & combo summary

• Opening a starter: P(≥1) ≈ 0.34 · 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

• Jurrac core is highly accessible (archetype core group about 0.96 in opening hand)
• Broad hand-trap and negation coverage (11 hand-trap-type cards, Astero, Evolzar, Crossout Designator)
• Strong Extra Deck ATK spread for closing (TY-PHON 2900, Baronne 3000, Meteor 2800)

Weaknesses

• List is illegal: Called by the Grave is Forbidden, Droll & Lock Bird and Maxx C exceed copy limits
• No side deck, so no post-side adaptability
• Heavy Dinosaur gating and off-archetype slots reduce core purity (30.9% exact-name)
• No combo evidence, so the real ceiling and median are unmeasured

Critical choke points

• Forbidden and over-limit cards make the list unplayable as built until fixed
• Dinosaur-count gating for Megalo and Aeolo; a hand without a Dinosaur starter stalls the engine
• Single Meteor board-wipe is self-destructive if the board is not ready

Recommended changes

Evidence & confidence

• Verified: Deck is Illegal: Called by the Grave Forbidden x2, Droll & Lock Bird 3 vs limit 2, Maxx C 2 vs limit 1; Main 40 and Extra 15 are within Master Duel size rules; side deck is 0; Extra Deck ATK values as listed in evidence cards; Archetype core group open at least once in a 5-card hand: 0.96
• Observed: Usage statistics: 7 of 25 archetype-core cards present (28%)
• Inferred: Engine consistency and brick rate estimates from hypergeometric draw table and card text; Going-first and going-second plans from card text and archetype structure; Interaction density from negation and removal text
• Provisional: Meta Power and matchup fit: no dated metagame sample or tournament link
• Data gaps: no combos supplied; combo floor, median and ceiling are text-only inference no tournament link; archetype meta-share and per-pilot match record absent no win-rate telemetry (going-first/second, matchup, brick/starter rates) no side deck submitted; post-side plan not assessable Meta Power provisional without a dated metagame sample guide evidence is a single short snippet with no section content
