White Forest Deck #770728 — Yu-Gi-Oh! OCG

Deck — Deck Power Evaluation

Final Contextual Deck Power: 30/100 (±10 · Confidence: Medium)

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

Legality

Main 52 / Extra 18 / Side 0 — status under the rules at evaluation time: Illegal. 4 violation(s).

Identity & game plan

• Win condition: Extra Deck boss monsters (Diabell, Diabellstar and Azamina Fusion/Synchro bodies) summoned off a White Forest / Sinful Spoils engine (Inferred from card text and archetype core); Azamina Fusion pressure through the Fusion Summon engine (Elzette, The Hallowed Azamina, Tales of the White Forest)
• Turn 1 (going first): Open a LIGHT Spellcaster or Illusion starter (Elzette, Silvy, Diabellstar the Black Witch) and chain White Forest searches into an Extra Deck boss (Inferred)
• Turn 2 (going second): Use Ash Blossom, Droll & Lock Bird and Evenly Matched style interaction to slow the opponent's first turn, then convert into a Synchro or Fusion boss (Inferred)
• Recovery: Recover from interaction with the Diabell and Sinful Spoils recursion cards in the GY and Filia Diabell banish effects (Inferred)
• After siding: Not evaluable: the deck has no Side Deck, so there is no post-side plan

Why it scores here

This OCG White Forest list is scored as a connected system, not as an average of its card scores. Its archetype core is well represented, with P(at least one core card in a 5-card opening hand) of about 0.89 (Inferred), so it usually reaches a starter, but its engine is diluted: only 15 of 52 Main Deck copies are the exact White Forest name, and 55 copies are off-archetype (Sinful Spoils, Mulcharmy, Azamina, Diabell, Artifact and others). Rciela and Silvera, two of the highest-inclusion core Extra Deck cards, are absent. Interaction is broad (9 hand traps and 10 negation-text cards) and gives a reasonable end-board, but there are no recorded boards, so ceiling and median output cannot be measured and are inferred from text only. The deck is Illegal: Ash Blossom and WANTED are over their copy limits, and the Extra Deck has 18 cards against a maximum of 15. The deck has no Side Deck, so it has no post-side plan. Popularity and archetype usage did not earn points; the score is capped at 30 as a theoretical, structural-only read.

Dimension scores

How the score was computed

Strategy profile: Midrange primary, Combo secondary (approximately 80/20 by evidence). Structural ≈ 46, Going First ≈ 48, Going Second ≈ 44, Meta = provisional, Tournament Reliability ≈ 42. Modifiers: Illegal deck cap (-5); Banlist exposure (-3); Engine compactness (-3); No Side Deck (-2); Dependence on missing core Extra Deck cards (-2). Final formula: Illegal deck: theoretical structural read only. Normal formula would give 0.80*46 + 0.20*42 - 10 (modifiers) = 35; capped to 30 per the Illegal rule. Meta provisional.

Probability & combo summary

• Opening a starter: P(≥1) ≈ 0.89 · 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

• Archetype core is accessible: about 0.89 chance of at least one core card in a 5-card opening hand (Inferred)
• Layered interaction from 9 hand traps and 10 negation-text cards (Inferred)
• Redundant search and recursion text across White Forest, Sinful Spoils and Diabell (Inferred)

Weaknesses

• Illegal in OCG: two cards over copy limit and Extra Deck over size (Verified)
• Off-archetype dilution: 55 of 70 engine-relevant copies are not exact White Forest (Verified)
• No Side Deck for best-of-3 play (Verified)
• No recorded boards, so consistency and combo output cannot be verified (Verified)

Critical choke points

• Starter access depends on a LIGHT Spellcaster or Illusion opener; losing those to hand traps or a board wipe stalls the White Forest engine (Inferred)
• Extra Deck slots are over the 15-card limit, so the list cannot be played as built in OCG (Verified)

Recommended changes

Evidence & confidence

• Verified: Illegal status: Ash Blossom 3 vs 2 legal, WANTED 3 vs 1 legal, Extra Deck 18 vs 15 (OCG); Side Deck count 0; Exact-name purity 21.4% (15 of 70 copies); Archetype core inclusion figures from usage_statistics
• Inferred: Opening-hand starter probability about 0.89 (hypergeometric, Main Deck only); Hand-trap coverage and interaction quality from card text; Going-first and going-second estimates
• Provisional: Meta and matchup fit (no dated metagame sample or 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 are absent no win-rate telemetry: going-first, going-second, matchup and brick rates are Inferred or Unknown Meta Power is Provisional unless a dated metagame sample is supplied No Side Deck supplied, so post-side performance cannot be assessed
