White Forest Deck #770733 — Yu-Gi-Oh! OCG

Deck — Deck Power Evaluation

Final Contextual Deck Power: 35/100 (±8 · Confidence: Low)

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

Legality

Main 52 / Extra 18 / Side 0 — status under the rules at evaluation time: Illegal. 3 violation(s).

Identity & game plan

• Win condition: Synchro Summon boss monsters from the Extra Deck (Diabell, Queen; Diabellstar Vengeance and Diabellze as board-breaking bosses; Chaos Angel, Arms of Genex Return Zero and Malong as closers) after building a board with Toy and Diabell cards.; Mulcharmy draw-engine chip damage and Diabell board-wipe sequences (Curse of Diabell) as a grind route.
• Turn 1 (going first): Open Elzette / Silvy / Rucia-style starters with a White Forest or Toy searcher, Special Summon a Tuner, then Synchro into Diabell Queen or Diabellze while holding Ash Blossom and Solemn Judgment for responses.
• Turn 2 (going second): Use Ash Blossom, Solemn Judgment and Typhoon / Forbidden Droplet to answer the opponent's first board, then rebuild through Diabell searchers (Filia Diabell, Curse of Diabell, Tales of the White Forest) into a Synchro boss.
• Recovery: Recycle Synchro Materials through Diabell Queen and Rucia / Poplar graveyard effects, and recover White Forest Spell/Traps from the GY via Woes of the White Forest and Tales.
• After siding: Not applicable: the deck has an empty side deck, so there is no post-side plan.

Why it scores here

The deck is scored as a system: its Extra Deck boss density (several 2500+ ATK Synchros) and its searcher and hand-trap package give it a plausible Midrange plan. Consistency is moderate: the 16-copy archetype core has an estimated 85% chance of at least one card in a 5-card opening hand, but it is split across four overlapping engines (White Forest, Toy, Mulcharmy, Diabell) plus off-theme dead slots. Interaction is real (Ash Blossom, Solemn Judgment, Typhoon, Forbidden Droplet, Curse of Diabell), but it is limited by the copy-limit violations and the empty side deck. Popularity and archetype stats (White Forest core inclusion above 50%) confirm the list is real and accessible but added no points on their own. The list is Illegal, so the final score is capped at a theoretical, structural-only read of 35.

Dimension scores

How the score was computed

Strategy profile: Midrange. Structural ≈ 53, Going First ≈ 48, Going Second ≈ 52, Meta = provisional, Tournament Reliability ≈ 45. Modifiers: Copy-limit and banlist exposure (-6); Extra Deck over size limit (-3); Engine conflict (-4); Empty side deck (-2); Illegal-list cap (-4). Final formula: Theoretical structural-only read (Illegal list). Structural 52.7 from Midrange weights. Unrestricted formula 0.80*53 + 0.20*45 = 51.4; modifiers -12 gives 39.4; capped to 35 because the list is Illegal.

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

• Dense searcher and hand-trap package (14 searchers, 6 hand traps)
• Large Synchro boss pool with several 2500+ ATK closers
• Layered interaction: Typhoon, Forbidden Droplet, Solemn Judgment, Curse of Diabell, Arms of Genex Return Zero

Weaknesses

• Illegal list: two copy-limit violations and Extra Deck over 15
• Four overlapping engines dilute consistency
• Dead or conditional slots: Winged Dragon Sphere Mode x2, Snake-Eyes x2, Mulcharmy empty-field effects
• Empty side deck removes all post-side adaptability

Critical choke points

• Ash Blossom is over the Semi-Limited limit, so the deck cannot be entered legally as built
• Diabell Queen copies (4 vs 3 allowed) are the main Synchro boss route
• Without Filia Diabell or Curse of Diabell the Diabell line has no reliable searcher

Recommended changes

Evidence & confidence

• Verified: Illegal status and copy-limit violations (Ash Blossom 3 vs 2; Diabell Queen 4 vs 3); Extra Deck count 18 vs OCG max 15; Empty side deck (side_count 0); Card stats and text as listed in evidence
• Observed: Archetype core inclusion rates from usage_statistics (verified stat, but see data gap on in_this_deck flags)
• Inferred: Starter consistency (P 0.855 core group, 0.807 searcher group); Brick and dead-card estimates; Interaction and board-breaking reads from card text; Engine-conflict assessment
• Provisional: Matchup and format fit (no dated meta); Meta Power (null)
• Data gaps: Deck is Illegal: copy-limit violations and Extra Deck over size make the final score theoretical No combos supplied: combo floor, median and ceiling are text-only inference No tournament link: archetype meta share and per-pilot records are absent usage_statistics in_this_deck flags conflict with cards[]: Rciela, Silvera, Poplar of the White Forest and Chaos Angel appear in the Extra Deck in cards[] but are flagged in_this_deck false; the flags seem to count the Main Deck only, so they were not used for core-presence No win-rate telemetry exists (going first/second, matchup, brick and starter rates) No side deck, so no post-side evaluation is possible Meta Power is Provisional
