Legality

Main 55 / Extra 15 / Side 0 — status under the rules at evaluation time: Illegal. 3 violation(s).

Identity & game plan

  • Win condition: Level 10 Sacred Beast hand-summons (Raviel, Calamity of the Sacred Beasts, Uria) and the Chaotic Phantasmal Sacred Beasts fusion, reached through searcher chains; Fiendsmith and Thunder Dragon Extra Deck threats via Fiendsmith's Tract / Fiendsmith's Lacrima and Thunder Dragon Colossus
  • Turn 1 (going first): Sacred Beasts Thunderclap or Martyr of the Sacred Beasts to search a Level 10 Sacred Beast, then Summoner or Released into a hand-summon Level 10 monster; Ash Blossom and Droll & Lock Bird protect the line
  • Turn 2 (going second): Hand traps (Ash Blossom, Infinite Impermanence, Ghost Belle, Droll & Lock Bird) break the opponent's first-turn play, then rebuild through the Phantasm GY-recursion text
  • Recovery: Sacred Beast monsters recur from GY and banishment via Fallen Paradise of the Sacred Beasts, Sacred Beasts Released and Martyr (text only, unverified in play)
  • After siding: No side deck is registered (side_count 0), so there is no post-side plan

Why it scores here

The structural read is built on the deck as a system: a searcher-dense Sacred Beasts engine (23 searcher-text cards, P(at least one in a 5-card opening hand) ≈ 0.94) reliably finds a Level 10 hand-summon, and the archetype core is almost always present (P ≈ 0.99, Inferred). Interaction is broad (16 hand-trap-text cards, P(at least one hand trap in a 6-card going-second hand) ≈ 0.89, Inferred), which lifts the going-second and interaction dimensions. Those strengths are offset by a diluted build: 70 of 73 archetype copies are off-archetype or generic, 21 tech/hand-trap slots compete for space, and there is no recorded combo data for a median or ceiling read. The deck is Illegal as submitted (Forbidden Kashtira Fenrir ×2, Semi-Limited Ash Blossom ×3, Limited Fiendsmith Engraver ×2), so it receives a capped, theoretical score. Popularity and archetype usage did not earn points, and card scores were not averaged.

Dimension scores

# Dimension Score Evidence
D1 Engine Accessibility & Consistency 62 P(≥1 searcher in 5-card hand) ≈ 0.94; core archetype P(≥1) ≈ 0.99; Level 10 hand-summon access is the real bottleneck (Inferred)
D2 Opening-Hand Quality & Brick Management 45 21 tech and 16 hand-trap-text slots with few redundant engine pieces raise dead-card risk; no brick measurement exists (Inferred)
D3 Combo Conversion & Ceiling 60 Thunderclap / Martyr / Released / Calamity / Raviel chains give a high ceiling on paper, but no recorded boards exist (Inferred, text-only)
D4 Combo Floor & Median Output 45 No recorded boards, so median output is unknown and set conservatively (Provisional)
D5 Interruption Resilience & Route Redundancy 55 Multiple searchers and hand traps give some route redundancy, though the Level 10 hand-summon is a single point of failure (Inferred)
D6 Resource Economy, Recovery & Grind 50 Sacred Beast GY and banish recursion exists in text but was not verified in play (Inferred)
D7 End-Board & Interaction Quality 62 16 hand-trap and 11 negation-text cards, 22 removal-text cards; breadth is high but some are Limited or Semi-Limited (Verified flags / Inferred)
D8 Going-Second & Board-Breaking Power 55 Going-second hand-trap density is strong (P ≈ 0.89), with Raviel and Calamity as board breakers (Inferred)
D9 Offensive Pressure & Closing Power 58 4000-ATK Raviel and Calamity and a 5000-ATK Chaotic fusion give closing power, but the board needs to be assembled first (Inferred)
D10 Main Deck Efficiency & Flexibility 40 55 main cards with 28 distinct names and 70 off-archetype copies make the engine diluted and not compact (Verified composition / Inferred)
D11 Extra Deck Efficiency & Coverage 55 15 Extra Deck cards spread across Link, Fusion and Xyz from several archetypes; flexible but low coherence (Verified composition)
D12 Side Deck Adaptability 15 No side deck is registered (side_count 0), so no post-side adaptability exists (Verified)
D13 Matchup Coverage & Format Fit 45 No tournament link or dated meta sample; archetype meta-share not available (Provisional)
D14 Pilotability & Error Tolerance 35 Multi-archetype engine with several Level 10 summon conditions and three legality-sensitive card slots is demanding to pilot (Inferred)

How the score was computed

Strategy profile: Combo primary, Midrange secondary (structural only; illegal cap applied). Structural ≈ 53, Going First ≈ 55, Going Second ≈ 55, Meta = provisional, Tournament Reliability ≈ 42. Modifiers: banlist exposure (-10); engine conflicts / no side (-2). Final formula: Illegal deck: theoretical only. 0.80*Structural(53) + 0.20*TournamentReliability(42) = 42.8, then modifiers −12 (capped at the rubric's −12 floor), giving 30

Probability & combo summary

  • Opening a starter: P(≥1) ≈ 0.94 · 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 text (23 cards) gives high opening-hand access to the engine
  • Broad interaction with 16 hand traps and 11 negation-text cards
  • Strong Level 10 Sacred Beast and Chaotic fusion finishers

Weaknesses

  • Illegal list: Forbidden Kashtira Fenrir and two over-limit restricted cards
  • Only 0 exact-name Phantasm copies; the build is a splash across four archetype families
  • No side deck (side_count 0)
  • No recorded combos, so the median and ceiling are text-only

Critical choke points

  • Level 10 Sacred Beast hand-summon condition (Raviel, Calamity, Uria: 7 copies)
  • Legality: the list cannot be played until Kashtira Fenrir ×2, Ash Blossom ×1 and Fiendsmith Engraver ×1 are removed
Priority Remove Add Reason
1 Kashtira Fenrir ×2 Phantasm or Sacred Beast playable (copies of legal Phantasm cards already in the main, or a legal Level 10 Sacred Beast) Forbidden card; the deck is illegal until it is removed
2 Ash Blossom & Joyous Spring ×1 and Fiendsmith Engraver ×1 Legal copies or the lowest-impact tech slot Over the Semi-Limited and Limited copy caps
3 Off-archetype tech cards (e.g. Ghost Belle, Ghost Ogre) where redundant Sacred Beast or Phantasm searchers Raises engine density and reduces brick risk
4 None A 15-card side deck Side deck is empty, so the deck has no post-side plan

Evidence & confidence

  • Verified: Legality violations and banlist status for Kashtira Fenrir, Ash Blossom, Fiendsmith Engraver, Called by the Grave and others; Main 55 / Extra 15 / Side 0 counts; Archetype purity: 0 exact-name copies; 70 off-archetype copies
  • Inferred: P(≥1 searcher in 5-card hand) ≈ 0.94; P(≥1 hand trap in 6-card going-second hand) ≈ 0.89; Going-first and going-second estimates
  • Provisional: Meta Power (null); no dated metagame sample; D13 matchup fit
  • Data gaps: No combos supplied: floor, median and ceiling are text-only inference No tournament link: archetype meta-share and pilot match record absent No win-rate telemetry exists in YGOVN Meta Power is Provisional unless a dated metagame sample is supplied Deck title is null
