White Forest Deck #774353 — Yu-Gi-Oh! Master Duel

Deck — Deck Power Evaluation

Final Contextual Deck Power: 65/100 (±8 · Confidence: Medium)

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

Legality

Main 43 / Extra 15 / Side 0 — status: Legal.

Identity & game plan

• Win condition: Synchro pressure from the Elfnote and White Forest Synchro pool (June Pride 3100 ATK, Diabell, Baronne de Fleur) once the Extra Deck is live; Hand-trap and negation-backed attrition: 9 hand traps and about 11 negation effects stall the opponent until a Synchro lands
• Turn 1 (going first): Turn 1: Special Summon Elfnote Lucina or Elfnote Tinia from hand, then use Witch of the White Forest or Silvy to search a White Forest or Elfnote card and build toward a Level 6 to 10 Synchro
• Turn 2 (going second): Hold Ash Blossom, Ghost Ogre and Effect Veiler for the opponent's first activations, then Synchro over the first board using Elfnote Power Patron or Rucia as Tuners
• Recovery: Silvera, Rciela and Diabell return from the GY through their own effects, and Witch and Mulcharmy Fuwalos supply recursive card flow
• After siding: Not applicable: the master-duel size rules here allow 0 side cards, so no post-side plan is in the evidence

Why it scores here

The deck opens reliably: the archetype-core group (23 copies) has an estimated 98% chance of at least one card in a 5-card opening hand, and Elfnote Lucina and Tinia self-summon from hand, which keeps the engine live on turn 1 (Inferred). Interaction is the strongest system trait: nine hand traps, roughly eleven negation-text effects and twelve removal-text effects, with an estimated 78% chance of at least one hand trap in a going-second 6-card hand (Inferred), so the deck can stall a board it does not yet control. Synchro recursion (Silvera, Rciela, Diabell) and Witch and Fuwalos card flow give it some grind and resilience. The score does not reflect any recorded combo or win-rate data; combo floor and ceiling are text-only inference, and Meta Power is provisional. Popularity and archetype stats were not counted as power, and no card scores were averaged into the deck score. Engine scatter (archetype purity about 21%, with Snake-Eye, Sinful Spoils, Kewl Tune and Yang Zing splashes) and the lack of a side deck hold the score back.

Dimension scores

How the score was computed

Strategy profile: Midrange primary; Control considered in interaction read only (no separate weighting). Structural ≈ 66, Going First ≈ 66, Going Second ≈ 70, Meta = provisional, Tournament Reliability ≈ 62. Modifiers: Engine conflicts (-3); Engine compactness (2). Final formula: 0.80*Structural + 0.20*TournamentReliability + ContextModifiers (Meta provisional; Structural = 6314/95 = 66.5)

Probability & combo summary

• Opening a starter: P(≥1) ≈ 0.32 · key two-card combo ≈ — · full-brick estimate ≈ 0.02 (all Inferred)
• Combo output: best PowerIndex —, median —, board-per-starter —
• Turn order: 0 going-first lines vs 0 going-second lines

Strengths

• Compact, redundant engine: 23 archetype-core copies with about 98% opening-hand access (Inferred)
• Dense interaction: 9 hand traps plus negation and removal effects across both decks (Inferred)
• Synchro recursion gives repeatable access to the Extra Deck (Inferred)

Weaknesses

• No side deck in Master Duel size rules, so no post-side adaptation (Verified)
• Engine scatter across about 12 sub-archetypes lowers coherence (Verified)
• No recorded combo or win-rate data to confirm conversion (Verified)

Critical choke points

• Single-copy Level 6 to 10 Synchro access depends on the Tuner in hand or field
• Interaction-heavy hand relies on Ash, Droll and Veiler, which are dead without a target

Recommended changes

Evidence & confidence

• Verified: Legal: 43 Main, 15 Extra, 0 Side within Master Duel size rules; Restricted cards Maxx C (1), Crossout Designator (1) and Droll and Lock Bird (2) are all at legal copy counts
• Observed: Usage stats: 25 archetype rows, 12 core cards present in this deck
• Inferred: Opening-hand access and brick estimates from hypergeometric draw tables; Interaction density from card text; Going-second hand trap odds
• Provisional: Meta Power (null, no dated metagame sample); Side deck and matchup adaptability; Tournament reliability
• 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, matchup and brick rates are Inferred or Unknown Meta Power is Provisional unless a dated metagame sample is supplied Master Duel size rules allow 0 side cards, so post-side plan is not evaluable
