White Forest Deck #773913 — Yu-Gi-Oh! Master Duel

Deck — Deck Power Evaluation

Final Contextual Deck Power: 51/100 (±8 · Confidence: Medium)

• Primary strategy: Toolbox
• Secondary strategies: Midrange, Tempo
• Format: master-duel

Legality

Main 40 / Extra 15 / Side 0 — status: Legal.

Identity & game plan

• Win condition: Synchro, Fusion and XYZ boards built from White Forest and Azamina pieces, closing with Azamina Mu Rcielago (-500 ATK to opposing monsters), Diabell/Baronne/Chaos Angel and Divine Arsenal, with Ame no Murakumo as a mass-destruction finisher.; Ritual pressure from Ame no Murakumo / Habakiri via Mitsurugi Ritual and Mitsurugi Mirror, plus Azamina Fusion double battle damage.
• Turn 1 (going first): Hand-summon Elzette of the White Forest (send a Spell/Trap from hand), search a White Forest or Mitsurugi piece with Witch, Silvy or Elzette, then convert into a Synchro or Fusion board using Astellar and Rucia as tuner access.
• Turn 2 (going second): Hold Ash Blossom, Droll and Maxx C to protect the first starter (P(>=1 hand trap in 6 cards) about 0.65), then search and extend through the opponent's board with Herald and Baronne negation/removal text.
• Recovery: Searchers (Silvy, Mitsurugi no Mikoto Kusanagi, Witch, Tales, Silvera) and graveyard recursion (Rucia, Silvy, Astellar) rebuild the board; Diabell and Rciela can return from the graveyard as synchro-tuner access.
• After siding: None: the deck runs no Side Deck, so there is no post-side plan. Best-of-3 play is unadapted.

Why it scores here

The deck reliably opens searchers (P(>=1 searcher text in opening 5) about 0.98) and has a moderate chance of a hand-summoned White Forest starter going first (about 0.51 for the five Elzette-family and Rucia cards together, Inferred). Its conversion comes from several different engines (White Forest, Azamina, Mitsurugi, Chaos, Herald), so the system has multiple routes but also conflicting resource needs. Interaction is dense (3 Ash Blossom, 2 Droll, Maxx C, Herald, Baronne, Mitsurugi Great Purification, Ame no Murakumo) and gives it a credible going-second plan (about 0.65 of 6-card hands contain a hand trap). The score is not driven by White Forest's popularity, and it is not an average of the card scores; no combo ceiling or median was supplied, and the lack of a Side Deck caps the post-game plan.

Dimension scores

How the score was computed

Strategy profile: Toolbox. Structural ≈ 57.3, Going First ≈ 58, Going Second ≈ 62, Meta = provisional, Tournament Reliability ≈ 50. Modifiers: Limited-card dependence (-2); Engine conflict (-3). Final formula: 0.80*Structural + 0.20*TournamentReliability + ContextModifiers (Meta provisional; 0.80*57.3 + 0.20*50 - 5 = 50.8, rounded to 51)

Probability & combo summary

• Opening a starter: P(≥1) ≈ 0.51 · 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

• Searcher density (20 searcher-text cards, P(>=1) = 0.976 in opening 5) gives strong access to pieces
• Layered interaction: 6 hand traps plus Herald, Baronne, Mitsurugi Great Purification and Ame no Murakumo
• High-ceiling closers: Chaos Angel, Ame no Murakumo, Divine Arsenal, Baronne, and Azamina Mu Rcielago's ATK aura
• Full Extra Deck (15/15) gives access to several summoning methods

Weaknesses

• No Side Deck, so there is no post-side adaptation
• Three engines (White Forest, Mitsurugi, Azamina) with 80 percent of copies off the exact archetype name create brick and conflict risk
• Starter gating: the Elzette family needs a Spell/Trap in hand, and the hand-starter probability going first is only about 0.51
• Many conditional pieces (Jigabyte, Triple Tactics Talent, Diabellstar, Gimmick Puppet) that play only in specific boards

Critical choke points

• A hand-summoned Elzette or Rucia going first (about 0.51 combined, Inferred)
• Single-copy Limited interaction and engine pieces (Herald, Maxx C, WANTED, Mitsurugi Prayers, Crossout Designator)
• Mitsurugi Ritual and Mirror requirements (Reptile tributes) when running the Ritual line

Evidence & confidence

• Verified: Legality: 40 main, 15 extra, 0 side, all restricted copies within legal copies; Limited cards at 1-copy cap and Semi-Limited cards at 2 copies (BanMasterDuel); Archetype purity: 11 exact-name copies of 55 (20 percent); Extra Deck composition: 7 Synchro, 4 XYZ, 2 Fusion, 2 Link; Usage stats: Witch and Silvy typical copies 3, deck runs 1 each
• Inferred: Starter access about 0.51 going first and 0.58 going second (hypergeometric proxy); Searcher redundancy (P(>=1) = 0.976); Going-second hand-trap coverage 0.65; Interaction density and board-breaking reads from card text; Pilotability and step-count estimates
• Provisional: Meta Power (null): no dated metagame sample supplied; Matchup and format fit (D13 = 50): archetype usage stats only
• Data gaps: No combos supplied: combo floor, median and ceiling are text-only inference No Side Deck (Side Deck size 0): post-side and D12 are structural only No tournament link: archetype meta-share and per-pilot record absent No win-rate telemetry (going-first/second, matchup, brick and starter rates): those signals are Inferred Meta Power is Provisional unless a dated metagame sample is supplied Evidence inconsistency: usage statistics marks Diabell, Rciela, Silvera, Baronne de Fleur, Chaos Angel, Azamina Mu Rcielago and Azamina Ilia Silvia as in this deck = false, yet they appear in the cards list with copies = 1. The missing core cards list was not used for scoring. Deck title is null; archetype label used as the reference name Guide coverage: one guide (White Forest Runick) with no section detail
