Legality
Main 55 / Extra 15 / Side 0 — status under the rules at evaluation time: Illegal. 2 violation(s).
Identity & game plan
- Win condition: Purrely Xyz boards (Epurrely Happiness, Expurrely Happiness, Epurrely Beauty) built from Purrely Quick-Play Memory chains, with Lava Golem / Radian / Kumongous as big-body finishers; Luce the Dusk's Dark fusion finisher (1 copy) and Lyrilusc Xyz beatdown
- Turn 1 (going first): Search and excavate Purrely Quick-Play Spells and Purrelyly / Purrely, then Xyz into an Epurrely with a Memory attached; unclear from text alone whether it reliably reaches a Xyz on T1-T2 without a second engine piece
- Turn 2 (going second): Open on hand traps (D.D. Crow, Skull Meister) and negations (Forbidden Chalice, Epurrely Beauty), then rebuild through Purrely searchers; Lava Golem is hard to use when the opponent has few monsters to Tribute
- Recovery: Purrely searchers (17 searcher-text cards) and recycling via the GY-attach Xyz text should refill the hand, but no boards were supplied to confirm recovery rates
- After siding: Not evaluable: the deck runs no side deck, so there is no post-side plan
Why it scores here
This deck is scored as a connected system, not as an average of its card scores. Its strongest feature is interaction breadth: 13 removal-text cards, 11 negation-text cards and 6 hand traps (D.D. Crow, Skull Meister) give it several ways to answer an opposing board, and that is the main reason it earns more than the rest of the dimensions. Its engine is the weak point: the Purrely searchers (17 searcher-text cards, about 0.86 chance of at least one in a 5-card opening hand, Inferred) reach a Purrely Xyz, but the deck is only 7 Kaiju cards and 63 off-archetype copies, so the Kaiju identity does not drive the list and the Purrely sub-engine is split across several related archetypes. With no recorded boards, no combos and no side deck, the floor, median and post-side scores stay near the middle or lower, and the popularity of the Purrely theme gave no points. The list is Illegal because Purrely Sleepy Memory runs 3 copies against a Semi-Limited limit of 2, so the structural score is capped at 25 per the legality rule and the result is theoretical only.
Dimension scores
| # | Dimension | Score | Evidence |
|---|---|---|---|
| D1 | Engine Accessibility & Consistency | 45 | P(at least one searcher in a 5-card opening hand) ~0.86 and per-copy starter odds ~0.25 at 3 copies; the Purrely Xyz route needs two or more specific pieces, so the engine is only partly live on T1-T2 (Inferred) |
| D2 | Opening-Hand Quality & Brick Management | 40 | Many off-engine pieces: 63 of 70 copies are off the Kaiju archetype name, Lava Golem needs opposing monsters to Tribute, and the 6 hand traps cost hand space when they are not needed (Inferred) |
| D3 | Combo Conversion & Ceiling | 55 | Ceiling from text only: Epurrely Happiness, Expurrely Happiness and Epurrely Beauty chain Memory attach and negation effects into a strong board, but no recorded boards exist to confirm the line (Inferred from text) |
| D4 | Combo Floor & Median Output | 40 | No combos supplied, so the median is unknown; the Purrely routes depend on a few key pieces and degrade quickly when those are missing (Inferred) |
| D5 | Interruption Resilience & Route Redundancy | 45 | Six hand traps and two independent interaction layers (Mystical Space Typhoon, Cosmic Cyclone) give some continuity after one interruption, but a single Purrely engine limits true redundancy (Inferred) |
| D6 | Resource Economy, Recovery & Grind | 50 | Purrely searchers and GY-attach recycling regenerate resources, and Mutiny in the Sky can rebuild a Fusion, but no float or grind data were supplied (Inferred from text) |
| D7 | End-Board & Interaction Quality | 62 | 13 removal-text and 11 negation-text cards, with Epurrely Beauty negating an effect monster each turn; durability depends on hand traps and on the Xyz staying on board (Inferred semantic read, with flags as Verified) |
| D8 | Going-Second & Board-Breaking Power | 50 | Hand traps and Forbidden Chalice help versus an established board, while Lava Golem and Radian give a larger body; no going-second split was supplied (Inferred) |
| D9 | Offensive Pressure & Closing Power | 50 | Top-end bodies include Radian (2800 ATK), Lava Golem (3000 ATK), Luce (3500 ATK, 1 copy) and Expurrely Noir (1100 ATK, 2800 DEF); no direct or piercing damage text was confirmed (Inferred) |
| D10 | Main Deck Efficiency & Flexibility | 45 | 55 Main cards with 22 distinct names; copy histogram is 3 one-copy, 5 two-copy and 14 three-copy cards; 30 level-0 spells, and the off-archetype count hurts coherence (Verified structure, Inferred coherence) |
| D11 | Extra Deck Efficiency & Coverage | 55 | 15 Extra cards (14 Xyz, 1 Fusion), all legal, with Purrely Epurrely and Expurrely cover; the single Luce and Lyrilusc slots add extra flexibility (Verified structure) |
| D12 | Side Deck Adaptability | 10 | No side deck at all (0 side cards), so the post-side plan is absent and best-of-3 adaptability is effectively zero (Verified) |
| D13 | Matchup Coverage & Format Fit | 35 | No tournament link and no dated metagame, so format fit is Provisional; the Illegal copy limit also stops any competitive read (Provisional) |
| D14 | Pilotability & Error Tolerance | 40 | Many chains with Xyz materials, Memory attaches and Tribute steps, and an off-archetype mix means many decision points; error tolerance is middling (Inferred) |
How the score was computed
Strategy profile: 0.8 Midrange + 0.2 Toolbox (Midrange primary; secondary profile unused in the arithmetic below for simplicity). Structural ≈ 46, Going First ≈ 44, Going Second ≈ 50, Meta = provisional, Tournament Reliability ≈ 38. Modifiers: Banlist exposure (-4); Engine conflicts (-4); Weak post-side plan (-2). Final formula: No reliable metagame: 0.80*Structural(46) + 0.20*TournamentReliability(38) = 44.4; + ContextModifiers (-10) = 34.4; capped to 25 because the deck is Illegal (rubric Step 2)
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
- Broad interaction: 13 removal-text and 11 negation-text cards plus 6 hand traps (Verified flags, Inferred semantic read)
- Searcher density: 17 searcher-text cards support a consistent Purrely draw/search base (Inferred)
- Full Extra Deck of 14 Xyz plus 1 Fusion gives flexible Xyz coverage (Verified structure)
Weaknesses
- Illegal list: Purrely Sleepy Memory over its Semi-Limited limit (Verified)
- Off-archetype spread: only 7 Kaiju copies, and 63 copies are off archetype (Verified)
- No side deck, so no post-side adjustment (Verified)
- No combo or board data, so no measured floor or median (Verified gap)
Critical choke points
- Purrely Xyz on board, which almost every line runs through (Inferred)
- Purrely Quick-Play Spell in hand for the Memory chain (Inferred)
Recommended changes
| Priority | Remove | Add | Reason |
|---|---|---|---|
| 1 | One copy of Purrely Sleepy Memory | Any legal Purrely Quick-Play or Spell card | Fixes the Illegal copy-limit violation (3 run vs 2 allowed), which is the cap on this score |
| 2 | Lava Golem (3 copies) | A card that works on an empty opposing board or a Purrely searcher | Lava Golem needs opposing monsters to Tribute and is weak as a going-second card in this list (Inferred) |
| 3 | Off-archetype Forbidden and Darklord pieces | Purrely or Kaiju support cards | Reduces engine conflicts and raises consistency (Inferred) |
Evidence & confidence
- Verified: Main 55 and Extra 15 sizes are legal for OCG; Purrely Sleepy Memory runs 3 copies against a Semi-Limited limit of 2 (Illegal); 0 side cards, 14 Xyz plus 1 Fusion in the Extra Deck; Archetype spread: 34 Purrely, 7 Kaiju, 63 off-archetype copies
- Inferred: Starter and searcher probabilities from the hypergeometric draw table; Interaction breadth from removal, negation and hand-trap text flags; Engine conflicts and brick risk from archetype spread and card text; Ceiling reads for the Epurrely and Expurrely Xyz lines from card text only
- Provisional: Meta power and format fit (no dated metagame or tournament link); Going-second share and matchup fit
- 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, brick or starter rates Meta Power is Provisional without a dated metagame sample No side deck, so post-side performance cannot be assessed Usage statistics show one row but no core cards, so the archetype core cannot be checked
