Sylvans Deck #767568 — Yu-Gi-Oh! OCG

Deck — Deck Power Evaluation

Final Contextual Deck Power: 25/100 (±10 · Confidence: Low)

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

Legality

Main 56 / 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 Noir) that grow through Purrely Quick-Play recursion, with Extra-Deck boss options (Super Starslayer TY-PHON, Divine Arsenal AA-ZEUS, Nibiru) as a late-game finisher (Inferred from card text; no combo boards recorded); Hand-trap and removal-led interaction (Ash Blossom, Infinite Impermanence, Evenly Matched, Harpie's Feather Duster, Lightning Storm) that wins by attrition on the field (Inferred)
• Turn 1 (going first): Open a Purrely starter (Purrely, Purrelyly, Stray Purrely Street) and search or excavate a Purrely Quick-Play memory into an Xyz; hold hand traps for the opponent's first board (Inferred)
• Turn 2 (going second): Use hand traps (13 in main) to disrupt the opponent's starter or first Extra Deck summon, then rebuild the Purrely Xyz engine with recursion (Inferred)
• Recovery: Purrely monsters return from the GY through the Quick-Play memory effects and the Xyz material-recursion text, so a broken board can rebuild from the GY (Inferred from card text)
• After siding: Not evaluable: the deck runs no Side Deck (side_count 0), so there is no post-side plan

Why it scores here

The score is built from the deck as a system and not from averaging card scores or from the popularity of the Purrely theme. The main deck reliably opens a Purrely starter: the archetype core is present in about 99.6% of five-card hands, which supports a high D1 (Inferred from the hypergeometric estimate). Interaction density is high, with 13 hand traps, 8 removal-text cards and 6 negation-text cards, which lifts D7 and D5. There are no recorded combo boards, so the ceiling and median (D3, D4) are text-only estimates and carry low weight. The deck has no Side Deck, which caps D12, and it is illegal at the copy limit (Ash Blossom and Foolish Burial Goods at 3 copies against 2 allowed), so the result is capped to a theoretical, structural-only score of 25.

Dimension scores

How the score was computed

Strategy profile: Midrange. Structural ≈ 59, Going First ≈ 62, Going Second ≈ 58, Meta = provisional, Tournament Reliability ≈ 52. Modifiers: banlist_exposure (-4). Final formula: Illegal: theoretical structural-only cap. Structural 59 with Midrange weights; 0.80*59 + 0.20*52 = 57.6; context modifiers -4 gives about 54; Illegal cap sets the final score to 25. Meta provisional (null).

Probability & combo summary

• Opening a starter: P(≥1) ≈ 1 · key two-card combo ≈ — · full-brick estimate ≈ 0 (all Inferred)
• Combo output: best PowerIndex —, median —, board-per-starter —
• Turn order: 0 going-first lines vs 0 going-second lines

Strengths

• Dense Purrely starter and archetype-core presence gives high opening-hand access (Inferred)
• Broad hand-trap and removal suite with 13 hand traps and 8 removal-text cards (Verified card text, Inferred role)
• Extra Deck offers multiple finishers across Xyz, Link and boss options (Verified listing)

Weaknesses

• Illegal at the copy limit for Ash Blossom and Foolish Burial Goods (Verified)
• No Side Deck, so no best-of-3 adaptation (Verified)
• Declared archetype Sylvans does not match the Purrely-led list (Verified)
• Heavy reliance on Xyz recursion for pressure; no recorded combo data to confirm the line (Inferred)

Critical choke points

• Purrely starter: the Purrely engine depends on a small set of starters that interaction can shut off (Inferred)
• Xyz summon: Extra Deck Xyz summons are the main conversion step and can be disrupted (Inferred)

Recommended changes

Evidence & confidence

• Verified: Illegal status: Ash Blossom & Joyous Spring and Foolish Burial Goods each run 3 copies against a Semi-Limited limit of 2; Main 56 / Extra 15 / Side 0 within OCG size rules; Side Deck is empty; Declared archetype Sylvans; 33 main-deck copies are Purrely-named; Card text and stats as listed in evidence
• Inferred: Starter access about 0.996 for the archetype core group (hypergeometric); Interaction density across hand traps, negation and removal text; Purrely Xyz recursion as the main pressure and recovery route; Going-first and going-second estimates
• Provisional: Meta Power (no dated sample); Format fit and matchup coverage (no tournament data)
• 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 in YGOVN: going-first/second, matchup and brick rates are Inferred or unknown Meta Power is provisional without a dated metagame sample Usage statistics flag several Extra Deck cards (Epurrely Plump, Epurrely Happiness, Epurrely Beauty, Expurrely Noir, Epurrely Noir, Sylvan Princessprite, Linkuriboh, TY-PHON, AA-ZEUS, Relinquished Anima, S:P Little Knight) as not in this deck, although cards[] lists them in the extra zone; core_present_pct 56 is therefore unreliable Declared archetype (Sylvans) conflicts with the Purrely-led contents; archetype purity 0% reflects the label, not the build
