Vernusylph/Vernalizer Fairy Deck #758518 — Yu-Gi-Oh! OCG

Deck — Deck Power Evaluation

Final Contextual Deck Power: 33/100 (±10 · Confidence: Low)

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

Legality

Main 54 / Extra 16 / Side 0 — status under the rules at evaluation time: Illegal. 5 violation(s).

Identity & game plan

• Win condition: Extra Deck summons (Naturia Barkion, Landoise, Mudragon, Masquerena, Vera-based board pressure) after Naturia and Vernusylph searches fill the Graveyard and Field; Fusion and Link pressure from Garura, Flame Wingman, Mudragon, Atypus and Underworld Goddess
• Turn 1 (going first): Open a Naturia or Vernusylph searcher, search a second-level Naturia monster, Tribute or Special Summon into Barkion or Landoise, and protect the board with Mind Mirror Force or Naturia negations
• Turn 2 (going second): Use Maxx C, Evenly Matched and Dominus Purge as hand interaction, then rebuild with Naturia Mole Cricket and Naturia Camellia to reach a synchro or link board
• Recovery: Rebuild from the Graveyard with Naturia Sacred Tree and Vernusylph searches, then re-Synchro through Naturia Camellia or Naturia Vein
• After siding: No side deck is listed, so there is no post-side plan to evaluate

Why it scores here

The deck reliably opens a searcher: P(at least one searcher-text card in a 5-card opening hand) is about 0.82, so the engine is accessible on paper (Inferred). Its interaction density is the strongest structural signal, with 14 negation-text and 13 removal-text cards across Naturia, Vernusylph and Trap support. Conversion is weak because the deck has no recorded boards at all, so the ceiling and median are text-only estimates, and the Extra Deck contains three Forbidden cards and a Fusion (Naturia Exterio) whose required Naturia Beast cannot legally be in the deck. The deck is also incoherent at archetype level: only 0 of 70 archetype-tagged copies are exact-name Vernusylph, and the rest spread across Naturia, Mulcharmy, Dominus, Charmer and Mirror Trap. Popularity and usage data did not earn points, since the usage statistics describe a Madolche core this list does not run; the score was built from the system, not by averaging card scores. The list is Illegal (three Forbidden cards, Naturia Sacred Tree at 3 copies against a limit of 1, and 16 Extra Deck cards against a limit of 15), so the score is capped and this is a theoretical, structural-only read.

Dimension scores

How the score was computed

Strategy profile: Midrange. Structural ≈ 47.5, Going First ≈ 46, Going Second ≈ 50, Meta = provisional, Tournament Reliability ≈ 35. Modifiers: banlist_exposure (-8); dependence_on_one_extra_card (-4). Final formula: 0.80*Structural + 0.20*TournamentReliability (Meta provisional); Illegal list capped low and theoretical/structural-only per the rubric

Probability & combo summary

• Opening a starter: P(≥1) ≈ 0.82 · 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

• High searcher density (15 searcher-text cards) gives strong opening-hand access
• Negation and removal density (14 and 13 text cards) across Naturia, Vernusylph and Trap support
• Real Extra Deck closers available: Naturia Barkion, Naturia Landoise, Vera the Vernusylph Goddess

Weaknesses

• Illegal list: Forbidden cards, an over-limit Naturia Sacred Tree, and 16 Extra Deck cards
• Sub-theme sprawl: Naturia, Vernusylph, Mulcharmy, Dominus, Charmer and Mirror Trap pieces compete for the same slots
• No recorded boards, so the combo ceiling and median are unmeasured

Critical choke points

• Naturia Beast is Forbidden, so Naturia Exterio cannot be summoned as intended
• Naturia Camellia and Naturia Vein are the only Tuner options reliably available for synchro lines

Recommended changes

Evidence & confidence

• Verified: Legality status Illegal: 3 Forbidden cards, Naturia Sacred Tree at 3 copies against a limit of 1, and Extra Deck 16 against a limit of 15; Naturia Beast is Forbidden and is the required Fusion material for Naturia Exterio; Main 54 cards, Extra 16 cards, Side 0 cards
• Observed: No recorded combo boards exist for this deck (total_combos 0)
• Inferred: P(>=1 searcher-text card in 5-card hand) about 0.82 (hypergeometric); Interaction density is high on a semantic read of card text; Going-second hand-trap access about 0.30 with 3 hand traps
• Provisional: Meta Power is null; no dated metagame sample or tournament link is supplied; Matchup and format fit are unmeasured
• 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 or starter rates) usage_statistics describe a Madolche core (2 of 15 present), which does not match this Vernusylph/Naturia list; the archetype usage data is probably mis-keyed and was not used for scoring No side deck listed, so post-side adaptability is unmeasurable Meta Power is provisional unless a dated metagame sample is supplied
