Purrely Deck #774335 — Yu-Gi-Oh! Master Duel

Deck — Deck Power Evaluation

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

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

Legality

Main 40 / Extra 15 / Side 0 — status under the rules at evaluation time: Illegal. 1 violation(s).

Identity & game plan

• Win condition: Link and Xyz boards built from Purrely and Yummy Special Summons, closing with Expurrely Noir and Epurrely Beauty (Inferred from card text; no recorded combos); Mulcharmy draw-and-hand-size pressure (Inferred from card text)
• Turn 1 (going first): Open with Purrely and Memory Quick-Play Spells to search Purrely material, then Link or Synchro into an Xyz (Inferred from text and hypergeometric odds)
• Turn 2 (going second): Hold Ash Blossom, Infinite Impermanence, Droll and Maxx C to answer the first opposing engine, then rebuild from the Purrely GY loop (Inferred)
• Recovery: Rebuild from the GY through the Purrely Quick-Play Spells and Mulcharmy draw effects (Inferred)
• After siding: No Side Deck is present, so there is no post-side plan

Why it scores here

The deck's engine is reasonably accessible: 24 Purrely-named copies and a 0.9988 proxy for at least one core card in a 5-card opening hand (Inferred). Interaction is dense, with 9 hand traps, 7 negation-text cards and the Herald and Crossout Designator removal options, which carries resilience and going-second strength. Its ceiling and floor cannot be measured because no recorded boards exist, so the combo scores come from card text only and are Inferred. Popularity was not rewarded and card scores were not averaged. The deck is Illegal (Purrely run 3 times against a limit of 2), so the structural score of about 52 is capped to 30 and marked theoretical only.

Dimension scores

How the score was computed

Strategy profile: Combo. Structural ≈ 52, Going First ≈ 55, Going Second ≈ 52, Meta = provisional, Tournament Reliability ≈ 46. Modifiers: banlist exposure (-6). Final formula: No reliable metagame: 0.80*Structural + 0.20*TournamentReliability = 0.80*52 + 0.20*46 ≈ 51; modifier -6 gives 45; capped to 30 because legality status is Illegal (theoretical/structural-only per rubric Step 2)

Probability & combo summary

• Opening a starter: P(≥1) ≈ 1 · 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

• Dense interaction: 9 hand traps and 7 negation-text cards
• Strong archetype core: 24 Purrely-named copies
• Redundant starters across Purrely Memory Spells

Weaknesses

• Illegal as built: Purrely at 3 copies against a limit of 2
• No Side Deck
• No recorded combos, so the ceiling and floor cannot be checked

Critical choke points

• Purrely is the engine piece and is over the copy limit
• The Extra Deck needs several specific Link, Synchro and Xyz materials to be live
