Lyrilusc Deck #775206 — Yu-Gi-Oh! OCG

Deck — Deck Power Evaluation

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

• Primary strategy: Combo
• Secondary strategies: Midrange, Toolbox
• Format: ocg

Legality

Main 55 / Extra 15 / Side 0 — status under the rules at evaluation time: Illegal. 1 violation(s).

Identity & game plan

• Win condition: Xyz Summon Epurrely / Expurrely monsters and convert attached Purrely Quick-Play Spells into board pressure and attacks; Lyrilusc Xyz beats and direct attacks from Lyrilusc - Assembled Nightingale / Ensemblue Robin, with Luce the Dusk's Dark as a single-copy fusion finisher
• Turn 1 (going first): Open a Purrely searcher (Purrely, Purrelyly, My Friend Purrely) or a Quick-Play memory, Normal/Special Summon into Purrely Xyz material, then use the Xyz effect to attach memories and add or search Purrely cards (Inferred from text)
• Turn 2 (going second): Use hand traps (D.D. Crow, Skull Meister, Buio the Dawn's Light) to answer the opponent's first play, then rebuild through the Purrely Xyz engine (Inferred from text)
• Recovery: Purrely excavation and search effects plus Quick-Play memory recursion from the GY to rebuild the Xyz engine after a disruption (Inferred from text)
• After siding: No side deck is registered (Side Deck size 0), so no post-side plan exists; the deck is evaluated on its main deck alone

Why it scores here

The deck is built around a Purrely Quick-Play memory and Epurrely/Expurrely Xyz engine. Its 17 searcher-text cards give P(at least one searcher in the opening 5) of about 0.86 (Inferred), so the engine is usually reachable on turn 1 to 2. Conversion is limited because no recorded boards exist, so the ceiling and median rest on text reads only and both sit around 40 to 45. Interaction density is reasonable (11 negation-text cards, 13 removal-text cards, 6 hand traps), which lifts the system's interaction score but not its board-breaking. The score is capped at 30 because the list is illegal (3 copies of a Semi-Limited card against a limit of 2) and the deck is built around the Lyrilusc name while running 4.3 percent exact-name purity, with 67 off-archetype copies from Kaiju, D.D., Forbidden and Darklord, which lowers coherence. Archetype popularity and meta share earned no points, and card scores were not averaged.

Dimension scores

How the score was computed

Strategy profile: Combo primary, Midrange secondary (approx. 4:1 not computed; Combo weights used directly). Structural ≈ 47, Going First ≈ 45, Going Second ≈ 42, Meta = provisional, Tournament Reliability ≈ 35. Modifiers: banlist exposure (-8); engine conflicts (-4). Final formula: Illegal deck: theoretical/structural only. Unconstrained 0.80*Structural(47)+0.20*TournamentReliability(35)+Modifiers(-12) = 33; capped at 30 per the Illegal rule

Probability & combo summary

• Opening a starter: P(≥1) ≈ 0.25 · 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 searcher text (17 cards) gives high engine access on the opening hand
• Layered interaction: 11 negation-text, 13 removal-text, 6 hand traps
• Purrely recursion and excavation give several restart routes

Weaknesses

• Illegal list: 3 copies of Purrely Sleepy Memory against a limit of 2
• Low exact-name purity (4.3 percent); the Lyrilusc core cards are absent so the deck does not run its named archetype
• Heavy off-archetype spread (Kaiju, D.D., Forbidden, Darklord) lowers coherence
• No side deck, so no post-side adaptability

Critical choke points

• Purrely Xyz engine: most lines require a live Epurrely or Expurrely on the field
• Single-copy Expurrely Happiness and Ensemblue Robin are finishers with no redundancy

Recommended changes

Evidence & confidence

• Verified: Legality: 55 main, 15 extra, 0 side; Purrely Sleepy Memory over its Semi-Limited limit (3 copies vs 2); Card text and copy counts resolved for all 22 main and 11 extra distinct cards; Archetype spread: Purrely 34, generic 18, Kaiju 7, D.D. 3, Forbidden 3, Lyrilusc 3, Darklord 1, Sylvan 1; Core Lyrilusc usage cards: 0 of 6 present
• Inferred: Opening-hand probabilities (hypergeometric, main deck only); Engine accessibility and brick rate estimates from card text; Interaction quality from negation and removal text; Going-first and going-second estimates
• Provisional: Meta Power (null, no dated metagame sample); Matchup coverage (D13); Post-side plan (D12, no side deck)
• 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 and starter rates) no side deck registered Meta Power is Provisional unless a dated metagame sample is supplied
