White Forest Deck #771679 — Yu-Gi-Oh! OCG

Deck — Deck Power Evaluation

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

• Primary strategy: Combo
• Secondary strategies: Stun, Toolbox
• 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: Synchro and Fusion Summon Azamina / Diabellstar / Chaos Angel-class bosses from the Extra Deck, then close with 2500-4000 ATK bodies; Diabell/Sinful Spoils recursion and Azamina Fusion pressure via Deception and Hallowed Azamina
• Turn 1 (going first): Open with Elzette / Silvy / Diabellstar the Black Witch to reach the White Forest and Diabell engine; protect the starter with Ash Blossom, Droll and Evenly Matched
• Turn 2 (going second): Use hand traps (Ash, Ghost Belle, Effect Veiler, Infinite Impermanence, Droll) to stop the opponent's first board, then convert through Extra Deck summons
• Recovery: Recover through GY-triggered effects (Silvy, Rucia, Astellar, Tales of the White Forest) and recursion of Spells/Traps via Like the Diabell and Curse of Diabell
• After siding: Not evaluable: the deck runs no Side Deck (0 cards), so no post-side plan exists

Why it scores here

This list is scored as a theoretical, structural-only read because it is illegal: three cards exceed their copy limits and the Extra Deck holds 18 cards against a maximum of 15. Its consistency reads as moderate: the core White Forest / Diabell group (18 copies) gives P(at least one in a 5-card opening) of about 0.89 (Inferred), but only 20% of the main deck is exact-name White Forest, so Mulcharmy, Azamina, Sinful Spoils and Diabell pieces compete for the same hand. Interaction is the strongest part of the system, with 17 negation-text and 14 removal-text cards, 13 hand traps and a 6-card going-second hand-trap group probability of about 0.84 (Inferred). Its ceiling is plausible from Extra Deck bosses such as Azamina (4000 ATK) and Chaos Angel, but no recorded boards exist, so median output and floor are provisional. The score comes from consistency, interaction and closing power evaluated on the system; it does not come from the archetype's popularity or from averaging card scores, and the Illegal status caps the final score at 30.

Dimension scores

How the score was computed

Strategy profile: Combo. Structural ≈ 55.3, Going First ≈ 52, Going Second ≈ 60, Meta = provisional, Tournament Reliability ≈ 40. Modifiers: banlist_exposure (-4); engine_conflicts (-3); no_side_deck (-2). Final formula: 0.80*Structural + 0.20*TournamentReliability (Meta provisional) = 52.3 before modifiers; context modifiers -9 gives 43.3; Illegal status caps the final score at 30 (theoretical/structural-only)

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

• Dense negation and removal suite (17 negation-text, 14 removal-text cards) with 13 hand traps
• Core White Forest / Diabell engine is highly accessible (core group P(>=1 in 5) ~0.89)
• Strong Extra Deck closers (Azamina 4000 ATK, Chaos Angel 3500 ATK, Snake-Eye Doomed Dragon 3000 ATK)

Weaknesses

• Illegal list: three copy-limit violations and an Extra Deck of 18 (max 15)
• Low exact-name archetype purity (20%) and cross-archetype engine conflicts
• No Side Deck, so no post-side plan in a best-of-3 format
• No recorded boards, so the combo ceiling and median output cannot be verified

Critical choke points

• Extra Deck size must drop to 15 or fewer before the list is playable
• The three over-limit cards (WANTED, Ash Blossom, Super Polymerization) must be brought to their legal copy counts
• Engine depends on a small number of starters (Elzette, Silvy, Diabellstar) that must be drawn together with hand traps

Recommended changes

Evidence & confidence

• Verified: Main count 52 and Extra count 18 (composition); Ash Blossom, Super Polymerization and WANTED exceed legal copy counts (legality violations); Extra Deck exceeds the 15-card maximum (size_warnings); No Side Deck is present (side_count 0); Exact-name archetype purity is 20% (archetype_purity)
• Observed: No recorded boards exist for this deck (combos_evidence total 0); Core archetype usage stats list 12 of 17 core cards present (usage_statistics)
• Inferred: P(>=1 core card in 5-card opening) ~0.89 from hypergeometric estimate; Interaction density is high based on negation and removal text plus 13 hand traps; Going-second hand-trap group ~0.84 probability; Combo ceiling plausible from Extra Deck boss text
• Provisional: Meta Power (no dated metagame sample supplied); Tournament reliability (no tournament link or win-rate telemetry); Median and floor combo output (no boards)
• Data gaps: no combos supplied; combo floor/median/ceiling is text-only inference no tournament link; archetype meta-share and per-pilot match record absent no win-rate telemetry for going-first/second, matchup, game-level, brick or starter rates Meta Power is Provisional unless a dated metagame sample is supplied no Side Deck; post-side plan cannot be assessed deck title is null; evaluation keyed on deck id 771679
