Legality

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

Identity & game plan

  • Win condition: Synchro and Fusion boss monsters (Diabellze, Chaos Angel, Azamina Sol Erysichthon, Dark Magician of Destruction) built off the White Forest and Azamina engine; Diabellstar and Azamina Fusion pressure, with Diabell Vengeance and Snake-Eyes Vengeance Dragon as backup bosses
  • Turn 1 (going first): Open a searcher (Witch, Elzette, Silvy, Tales) to add a White Forest or Azamina piece, then Synchro or Fusion into a boss while holding Ash Blossom and Ghost Ogre as interaction
  • Turn 2 (going second): Use hand traps (Ash Blossom, Ghost Ogre, Infinite Impermanence, Maxx C) to break the opponent's first combo, then rebuild through searchers and the Extra Deck
  • Recovery: Recover through the White Forest graveyard recursion effects and the Witch / Elzette search chain, which can rebuild a board after a clean negation
  • After siding: No side deck is registered in the export, so there is no evidenced post-side plan

Why it scores here

The deck scores on how the system behaves, not on the strength of its individual cards. Its 16 searcher-text cards and 13 archetype-core copies give a high chance of a live engine in the opening hand (about 0.88 for at least one core card in five, Inferred), so consistency is solid. Nine hand traps and about ten negation or removal effects give good interaction and a real going-second route (about 0.81 for at least one hand trap in six, Inferred). Conversion and median output cannot be measured because the export has no recorded boards, so both are estimated from card text only and kept moderate. Popularity and archetype usage were not credited: only 25.5 percent of cards carry the exact White Forest name, which splits the list across several sub-archetypes and costs some coherence. The missing side deck and the absence of a dated meta sample keep the score below its structural value.

Dimension scores

# Dimension Score Evidence
D1 Engine Accessibility & Consistency 74 Hypergeometric P(at least one core card in a 5-card opening hand) = 0.877 and P(at least one searcher) = 0.935; 3-copy starters Witch, Silvy and Ash give redundancy (Inferred)
D2 Opening-Hand Quality & Brick Management 66 Brick risk is moderate: many hand traps and non-engine spells dilute the hand, with 41 off-archetype copies against 14 exact-name copies (Inferred)
D3 Combo Conversion & Ceiling 60 No recorded boards; the ceiling comes from text-level reads of Diabellze, Chaos Angel and Azamina Sol Erysichthon and is not measured (Inferred)
D4 Combo Floor & Median Output 52 No combos supplied, so median output is unmeasured and estimated only from starter diversity and interaction density (Inferred)
D5 Interruption Resilience & Route Redundancy 68 Nine hand traps and two independent searcher families (White Forest and Azamina) give some route redundancy after one disruption (Inferred)
D6 Resource Economy, Recovery & Grind 55 Recursion and search text in Witch, Elzette, Rciela-style effects and the White Forest graveyard give some regrowth; no resource_signature data (Inferred)
D7 End-Board & Interaction Quality 70 Nine hand traps, about 11 negation-text cards and about 10 removal-text cards give layered interaction; Crossout Designator and Maxx C are Limited (Verified and Inferred)
D8 Going-Second & Board-Breaking Power 66 Going-second hand-trap density is strong (0.81 for at least one in six); no board-breaker count beyond text reads (Inferred)
D9 Offensive Pressure & Closing Power 66 Boss ATK values reach 2500 to 3500 across Diabellstar, Chaos Angel and Azamina Sol; closing relies on Extra Deck access (Verified stats, Inferred closing)
D10 Main Deck Efficiency & Flexibility 62 40 main cards with 26 distinct names, 18 singletons and a mix of 3-copy engine cards and single-copy tech; some slots are off-plan (Verified composition, Inferred efficiency)
D11 Extra Deck Efficiency & Coverage 60 All 15 Extra slots are filled with 7 Synchro, 7 Fusion and 1 Link, several of them overlapping in function across sub-archetypes (Verified composition, Inferred)
D12 Side Deck Adaptability 25 No side deck is present in the export, so there is no post-side adaptability (Verified; scored low)
D13 Matchup Coverage & Format Fit 50 No tournament link or dated metagame sample, so format fit is neutral and Provisional
D14 Pilotability & Error Tolerance 48 Several sub-archetype lines (White Forest, Azamina, Diabell, Sinful Spoils) and multiple tuners raise decision complexity (Inferred)

How the score was computed

Strategy profile: Midrange profile; Combo used as tie-breaker for the secondary strategy. Structural ≈ 61, Going First ≈ 60, Going Second ≈ 62, Meta = provisional, Tournament Reliability ≈ 55. Modifiers: No side deck (-2); Split sub-archetype identity (-2); Banlist exposure (-1). Final formula: 0.80*Structural + 0.20*TournamentReliability (Meta provisional); Structural 61.3, TR 55, pre-modifier 60, modifiers -5

Probability & combo summary

  • Opening a starter: P(≥1) ≈ 0.88 · key two-card combo ≈ — · full-brick estimate ≈ 0.12 (all Inferred)
  • Combo output: best PowerIndex —, median —, board-per-starter —
  • Turn order: 0 going-first lines vs 0 going-second lines

Strengths

  • Very high chance of a searcher or core card in the opening hand (Inferred)
  • Nine hand traps and layered negation give going-second resilience (Inferred)
  • Deep Extra Deck with boss options at 2500 to 3500 ATK (Verified stats)

Weaknesses

  • No recorded combo data, so output cannot be measured
  • No side deck, so no post-side plan (Verified)
  • Split across several sub-archetypes, lowering engine coherence (Verified composition)

Critical choke points

  • Dependence on the Witch / Elzette / Silvy starter cluster for the engine
  • Extra Deck boss access depends on Synchro and Fusion materials that the hand traps can consume
Priority Remove Add Reason
1 One off-archetype tech (Triple Tactics Talent or Infinite Impermanence) A second White Forest searcher or a side-deck slot Improves engine density and gives the deck a post-side plan
2 Limited tech copies in the main deck where a cheaper unrestricted negation exists Unrestricted negation or hand-trap options Reduces banlist exposure and makes the list easier to rebuild

Evidence & confidence

  • Verified: Legal main 40, extra 15, side 0 under master-duel size rules; Four cards Limited at 1 copy, all within legal copy count; Exact-name purity 25.5 percent; 16 archetype names in spread
  • Inferred: Hypergeometric starter and hand-trap probabilities (0.877 core, 0.935 searcher, 0.808 hand trap going second); Interaction density from card text (9 hand traps, 11 negation, 10 removal); Boss closing power from ATK values and text reads
  • Provisional: Format fit (D13) and meta power, pending a dated metagame sample
  • Data gaps: no combos supplied, so combo floor, median and ceiling are text-only inference no tournament link, so archetype meta-share and per-pilot match record are absent no win-rate telemetry, so going-first and going-second results are Unknown no side deck, so post-side performance cannot be scored Meta Power is Provisional unless a dated metagame sample is supplied
