Naturia Deck #753462 — Yu-Gi-Oh! OCG

Deck — Deck Power Evaluation

Final Contextual Deck Power: 25/100 (±8 · Confidence: Low)

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

Legality

Main 55 / Extra 15 / Side 0 — status under the rules at evaluation time: Illegal. 6 violation(s).

Identity & game plan

• Win condition: Extra Deck Synchro and Xyz boards (Naturia Landoise, Swordsoul Supreme Sovereign - Chengying, Garunix Eternity, Luce the Dusk's Dark, Vera the Vernusylph Goddess as a late-game closer); Vernusylph and Naturia recursion loops that rebuild the board from the Graveyard (Naturia Pumpkin, Naturia Bamboo Shoot, Vernusylph Thawing Mountains)
• Turn 1 (going first): Turn 1 Naturia searcher and summon chain (Naturia Mole Cricket, Naturia Camellia, Naturia Sacred Tree) into a Synchro or Xyz follow-up. Any single-copy starter has only about a 25% chance to appear in the opening five, so the plan leans on the three-copy cards.
• Turn 2 (going second): Skull Meister (3 copies) and Naturia Mole Cricket to respond to the opponent's first summon, then a Naturia Landoise or Vera negate-and-board line. There is no side deck to adjust this plan.
• Recovery: Vernusylph and Naturia Graveyard recursion (Vernusylph Flourishing Hills, Rose Girl, Naturia Marron, Miracle Fertilizer) to rebuild after a single disruption.
• After siding: None: the deck has zero side cards, so there is no post-side plan.

Why it scores here

The deck is illegal in OCG: three copies of Naturia Sacred Tree, two each of Keldo and Mudora where one is allowed, and Forbidden Naturia Rosewhip and Naturia Beast are all present, so the Final Contextual score is capped at 25 and the evaluation is structural and theoretical only. Structurally, the list has a real engine: searchers (17 searcher-text cards, P(at least one searcher in an opening five) about 0.86) and a 15-card Extra Deck with Synchro, Xyz and Fusion options that produce strong closers such as Vera, Chengying and Luce. The deck scores modestly on interaction (Landoise, Barkion, Stardust Dragon and Vera negations) and offensive closing power. Consistency is held back by low exact-archetype purity (32.9%, 47 of 70 copies off the Naturia name) that spreads the list across Vernusylph, Rose, Dark World, Fire King and Swordsoul pieces, and by the absence of any side deck. No combo boards, tournament link, usage stats or guides exist, so the combo and meta dimensions are text inference only. The score comes from consistency, interaction and closing power on the system, not from the Naturia name or from averaging card scores.

Dimension scores

How the score was computed

Strategy profile: Midrange. Structural ≈ 45, Going First ≈ 48, Going Second ≈ 42, Meta = provisional, Tournament Reliability ≈ 35. Modifiers: banlist_exposure (-8); illegal_cap (-10); no_side_deck (-2). Final formula: Illegal: uncapped 0.80*45 + 0.20*35 - 8 (banlist) = 35.2, capped to 25 per the illegal-deck rule; theoretical/structural only, Meta null

Probability & combo summary

• Opening a starter: P(≥1) ≈ 0.86 · 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

• Searcher density (17 cards) gives a high chance of a live starter in the opening five
• Wide Extra Deck (10 Synchro, 4 Xyz, 1 Fusion) with strong closers
• Multiple negation and removal routes (Landoise, Barkion, Stardust Dragon, Vera, Ashura King)
• Graveyard recursion (Pumpkin, Marron, Rose Girl) gives some recovery

Weaknesses

• Illegal list: 3 copies of Naturia Sacred Tree, 2 each of Keldo and Mudora, plus Forbidden Rosewhip and Beast
• Low exact-archetype purity (32.9%) spreads the engine across unrelated sub-archetypes
• No side deck, so no post-side plan
• Single-copy starters are unreliable in the opening hand

Critical choke points

• Naturia Sacred Tree and Naturia Mole Cricket (3-copy starters) carry the turn-1 line
• Forbidden Naturia Beast is the only Extra Deck Synchro that the Naturia line can use as a Synchro, so removing it breaks that route
• Skull Meister is the only going-second interaction, so the plan fails if it is not drawn

Recommended changes

Evidence & confidence

• Verified: Legality: 55 Main and 15 Extra; Forbidden Rosewhip and Beast; Limited Sacred Tree, Keldo and Mudora over the limit; Copy histogram 1/2/3 = 12/8/9; archetype purity 32.9%; Card text and stats for the listed Naturia, Vernusylph and Synchro cards
• Observed: No combo boards, so no observed frequency is available
• Inferred: P(at least one searcher in 5) ~0.86 from the hypergeometric table; Brick risk and starter reliability from copy counts and purity; Semantic read of negation and removal text
• Provisional: Meta Power (null) and D13 matchup fit, with no dated metagame sample
• Data gaps: No combos supplied: combo floor, median and ceiling are text inference only No tournament link: archetype meta-share and pilot record are absent No win-rate telemetry for going-first, going-second, matchup or brick rates Meta Power is Provisional without a dated metagame sample Deck title is null
