White Forest Deck #772486 — Yu-Gi-Oh! OCG

Deck — Deck Power Evaluation

Final Contextual Deck Power: 53/100 (±8 · Confidence: Medium)

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

Legality

Main 55 / Extra 15 / Side 0 — status: Legal.

Identity & game plan

• Win condition: Synchro-summon large LIGHT/DARK bosses (Diabellze the White Witch, Junora, Draco Berserker, Centur-Ion Legatia, Chaos Emperor) through the White Forest and Diabell searcher chain; Azamina Fusion/Synchro pressure with Saint Azamina and Azamina Sol Erysichthon, plus Toy and Diabell disruption
• Turn 1 (going first): Open a searcher (Elzette, Silvy, Toy Soldier, Filia Diabell) to reach a Tuner, Synchro into Poplar, Rciela or Silvera, and keep a hand trap (Infinite Impermanence, Skull Meister, Artifact Lancea) up for the opponent's first play
• Turn 2 (going second): Use hand traps and Mystical Space Typhoon / Magic Cylinder to answer the first board, then rebuild through recursion (Tales of the White Forest, Woes of the White Forest) into a boss
• Recovery: Recur Silvy and Rciela from the GY through their Synchro-return effects, and search back a Synchro or Diabell payoff with Tales and Filia Diabell
• After siding: No side deck is registered, so no post-side plan exists; any sideboarding requires a new list

Why it scores here

The deck reliably opens a functional plan because its searcher density is high: about 76% of opening hands (5 cards) contain at least one of the 13 archetype-core copies, and about 78% contain a searcher, which makes the White Forest and Diabell chain accessible on turn 1 or 2 (Inferred from the hypergeometric estimates). It converts that plan into pressure through a Synchro-heavy Extra Deck with several 2500 to 3500 ATK bosses, which lifts closing power. Interaction is layered: eight hand traps plus Magic Cylinder, Mystical Space Typhoon and Forbidden Chalice give it a real end-board answer set, though its going-second hand-trap hit rate (about 63%) is the main limit on board-breaking. Consistency and resilience are held back by a low archetype purity (about 26% exact-name), splashed sub-archetypes (Toy, Diabell, Azamina, Sinful Spoils, Artifact) and a 0-card Side Deck, which removes any post-side adaptation. Popularity and usage statistics confirm the list is a real, accessible build, but they did not raise the score, and card scores were not averaged into the deck score.

Dimension scores

How the score was computed

Strategy profile: Midrange primary, Toolbox secondary; Midrange weights used for Structural (no blend of weights applied). Structural ≈ 59, Going First ≈ 57, Going Second ≈ 60, Meta = provisional, Tournament Reliability ≈ 52. Modifiers: engine conflicts (-3); self-taxing or dead-slot card (-2). Final formula: 0.80*Structural + 0.20*TournamentReliability + ContextModifiers (Meta provisional, no dated metagame sample)

Probability & combo summary

• Opening a starter: P(≥1) ≈ 0.76 · 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 and Tuner density (about 78% of openers have a searcher)
• Eight hand traps plus several Quick-Play negates give layered interaction
• Strong Synchro bosses (Diabellze 2500, Junora 3100, Centur-Ion Legatia 3500)
• Full Extra Deck with on-plan Synchro and Fusion options
• All cards are Unlimited with no banlist exposure

Weaknesses

• No Side Deck registered, so no post-side plan
• Low exact archetype purity (25.7%) and several splashed sub-archetypes
• Going-second hand-trap coverage is about 63%
• Chain Energy and other narrow cards add dead-card risk
• No combo corpus, so the ceiling and median are unmeasured

Critical choke points

• Synchro Summon via Silvy, Rciela or Poplar: if the Tuner is not in the opening hand, the boss line stalls
• Diabell core (13 cores, 2 Diabell copies per archetype-core group) for board-breaking

Recommended changes

Evidence & confidence

• Verified: Main 55, Extra 15, Side 0; legal for OCG size and copy limits; All 31 main and 14 extra distinct cards are Unlimited; Exact-name archetype purity 25.7%; Extra Deck is 4 Fusion and 11 Synchro
• Observed: Archetype usage stats show 13 of 17 core cards present (47.1%) (usage stats only, not this deck's play)
• Inferred: At least one starter in a 5-card opener about 0.76; Searcher access about 0.78 in a 5-card opener; Going-second hand-trap hit rate about 0.63 in a 6-card hand; Consistency, interaction and resilience scores derived from text and composition
• Provisional: Meta Power is null and D13 is Provisional because no dated metagame sample or tournament link is supplied
• 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: going-first, going-second and matchup rates are Inferred or Unknown Meta Power is Provisional unless a dated metagame sample is supplied no side deck registered
