White Forest Deck #774156 — Yu-Gi-Oh! TCG

Deck — Deck Power Evaluation

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

• Primary strategy: Control
• Secondary strategies: Midrange
• Format: tcg

Legality

Main 54 / Extra 17 / Side 0 — status under the rules at evaluation time: Illegal. 2 violation(s).

Identity & game plan

• Win condition: Angelechy Extra Deck synchro bosses (Angelechy Bastion, Angelechy Shatranga, Angelechy Seneschal at 3000 ATK; Psychic End Punisher at 3500 ATK) summoned through Angelechy Problem and Angelechy Opposition, backed by continuous negation; Angelechy Destrier and Angelechy Castellan removal-on-summon plus Mulcharmy Fuwalos card-draw pressure
• Turn 1 (going first): Witch of the White Forest or Angelechy Strategy Score to search, Angelechy Problem to place an Angelechy Extra Deck monster on the field, then Angelechy Opposition to Special Summon a second Angelechy boss
• Turn 2 (going second): Hold Ash Blossom & Joyous Spring x3, Effect Veiler and Dominus Purge to answer the opponent's first activations, then use Angelechy Opening to e4 from the opponent's first Standby Phase to set up a board
• Recovery: Banish Angelechy Disturbance or Angelechy Opposition from the GY to add or Special Summon Angelechy cards; Witch of the White Forest and Angelechy Problem recur searches and placements
• After siding: Not evaluable: the deck runs no Side Deck (side_count 0), so there is no post-side plan

Why it scores here

The list is scored as a system, not as an average of its cards, and it is Illegal: Ash Blossom & Joyous Spring is run three times against a limit of two and the Extra Deck holds 17 cards against a maximum of 15, so the result is structural-only and capped. Its engine reliably opens: 15 searcher-text cards give an estimated 82% chance of at least one searcher in a 5-card opening hand (Inferred), and the Angelechy and White Forest search chain keeps the engine live on turn 1-2. Its interaction is the strongest part of the build: 19 removal-text and 15 negation-text cards, plus three Ash Blossoms, a Dominus Purge and Effect Veiler, give layered answers on both turns. Conversion and median output cannot be measured because the deck has no recorded boards, so D3 and D4 rest only on text reading and are low-confidence. Popularity did not earn points: the archetype usage data confirms the list is real but says nothing of strength, and the deck is mostly Angelechy (exact White Forest name purity 16.9%), which reduces engine coherence.

Dimension scores

How the score was computed

Strategy profile: Control. Structural ≈ 55, Going First ≈ 62, Going Second ≈ 60, Meta = provisional, Tournament Reliability ≈ 50. Modifiers: banlist exposure (-6); extra deck over size (-3); engine conflicts (-3). Final formula: Illegal list: structural-only. 0.80*Structural(55) + 0.20*TournamentReliability(50) = 54, plus modifiers -12 = 42, capped to 35 for an illegal list. Meta Power provisional (null).

Probability & combo summary

• Opening a starter: P(≥1) ≈ 0.26 · 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 interaction: 19 removal-text and 15 negation-text cards, including three Ash Blossom & Joyous Spring
• Searcher density gives a high chance (approx 82%) of a searcher in the opening hand
• Extra Deck bosses at 3000 ATK and Psychic End Punisher at 3500 ATK give closing power

Weaknesses

• Illegal as built: Ash Blossom over the copy limit and Extra Deck over the size limit
• Engine coherence is weak: 16.9% exact archetype purity, with Angelechy and White Forest cards split
• No Side Deck, so no post-side adaptation
• Only 15 monsters in 54 main-deck cards, creating monster-dependent hands

Critical choke points

• Three Angelechy Problem or Opposition copies are needed to place the Extra Deck bosses; a missing searcher or placement spell stalls the turn
• Extra Deck size 17 must drop to 15 before the list is legal

Recommended changes

Evidence & confidence

• Verified: Ash Blossom & Joyous Spring is run 3 times against a TCG limit of 2 (Semi-Limited); Extra Deck count is 17 against a TCG maximum of 15; Main Deck count is 54, within 40-60; Angelechy Bastion, Shatranga and Seneschal have 3000 ATK; Psychic End Punisher has 3500 ATK; Archetype exact-name purity is 16.9%, Angelechy is the largest sub-archetype with 29 copies
• Inferred: Searcher and starter access: P(at least one searcher in hand of 5) approx 0.82; Going-second hand-trap access: approx 0.46 in a 6-card hand; Interaction density (19 removal-text, 15 negation-text cards) gives strong end-board interaction; Brick risk is elevated by 15 monsters in 54 main-deck cards; Recursion through GY banish effects offsets resource spend
• Provisional: Meta Power (null: no dated metagame sample); Format fit and matchup coverage (D13), no tournament link; Post-side plan (D12), no Side Deck
• Data gaps: No combos supplied: combo floor, median and ceiling are text-only inference (total_combos 0) 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 Usage statistics conflict with the card list: in_this_deck is false for Diabell, Silvera, Rciela, Zalen, Visas Amritara, Psychic End Punisher, Angelechy Castellan, Angelechy Destrier and Angelechy Enlisted, but all appear in the cards array (zone extra). The missing_core list and the 16 of 25 core coverage figure are therefore unreliable and were not used for scoring No Side Deck: post-side performance cannot be evaluated
