Identity & game plan

  • Win condition: Sacred Beast Level 10 Special Summons (Infinity of the Sacred Beasts - Raviel, Calamity of the Sacred Beasts - Hamon) and Extra Deck boss monsters (The Chaotic Phantasmal Sacred Beasts, Superdreadnought Rail Cannon Gustav Rocket); Dark World recursion from the GY (Grapha, Reign-Beaux, Sillva) feeding Link and Fusion boards; Gustav Max direct damage
  • Turn 1 (going first): Search a Sacred Beast Level 10 with Card of the Soul or Sacred Beasts Released, reveal a Calamity or Infinity from hand to add a Sacred Beast spell or monster, then Special Summon a boss; Ash Blossom and Droll are held up to protect the first summon
  • Turn 2 (going second): Six-card hand with Ash Blossom, Ghost Ogre, Droll and Evenly Matched as interaction; use hand traps on the opponent's first meaningful activation and rebuild with Dark World recursion
  • Recovery: Martyr of the Sacred Beasts and Fallen Paradise of the Sacred Beasts recycle cards from the GY; Grapha and Reign-Beaux return from the GY via Dark World monsters; Sacred Beasts Released banishes from the GY for a Level 10 Fiend, Pyro or Thunder
  • After siding: No side deck is registered (Side Deck size 0), so there is no post-side plan; the deck cannot adapt between games in a best-of-3

Why it scores here

The deck opens reliably: searcher text is present in 27 of 55 Main Deck cards and the hypergeometric chance of at least one searcher in a 5-card opening hand is about 0.97, so a Sacred Beast Level 10 is usually reachable by turn 1 or 2. Its interaction layer is broad, with hand traps (Ash Blossom, Ghost Ogre, Droll, Evenly Matched) and destruction spells (Lightning Storm, Harpie's Feather Duster, Illusion Gate, Sacred Beasts Combined Assault), which lifts D7 and D8. Closing power is high on paper because the Extra Deck carries 4000-5000 ATK bosses, but the lines that reach them are unverified. The score is not earned from the Fiendsmith name: exact-name purity is 1.4% and the core Fiendsmith cards (Sequence, Requiem, Desirae, Tract) are absent, so the real build is a three-archetype mix (Phantasm, Dark World, Unchained) with engine conflicts. Popularity and the archetype label were not counted, and the score was built from the system, not from averaging card scores. The combo ceiling and median are text-only inference with no recorded boards, no side deck and no tournament data, so the band is wide.

Dimension scores

# Dimension Score Evidence
D1 Engine Accessibility & Consistency 66 P(at least 1 searcher in 5-card hand) ~0.97 from 27 searcher-text cards; the Sacred Beast Level 10 starter is about 0.25 per copy, so access is redundant but not guaranteed (Inferred)
D2 Opening-Hand Quality & Brick Management 62 Multiple searchers and 3-copy hand-trap singletons give functional openers, but 17 singletons and three archetype engines raise brick and conflict risk (Inferred)
D3 Combo Conversion & Ceiling 58 Calamity and Infinity text yields a strong Special Summon and search ceiling into Phantasm boss and Chaotic Phantasmal Sacred Beasts; no recorded boards to confirm (Inferred)
D4 Combo Floor & Median Output 45 combo data is empty (total combos 0), so the median is unknown and scored conservatively (Provisional)
D5 Interruption Resilience & Route Redundancy 60 Hand traps, Martyr recursion and Dark World GY revival give alternative routes after one interruption, but the Sacred Beast line has a single-choke Level 10 requirement (Inferred)
D6 Resource Economy, Recovery & Grind 62 Dark World GY recursion (Grapha, Reign-Beaux, Genta) and Sacred Beasts Released banish-to-hand give some regeneration, though Card Destruction and Fallen Paradise are only partly recursive (Inferred)
D7 End-Board & Interaction Quality 72 21 removal-text and 4 negation-text cards plus 8 hand traps give layered end-board interaction; the single Ash-Droll-Bird group is strong on paper (Inferred semantic read)
D8 Going-Second & Board-Breaking Power 66 Eight hand traps and Droll & Lock Bird help against an established board, and Gustav Max adds direct damage; going-second split is absent (Inferred)
D9 Offensive Pressure & Closing Power 74 Raviel and Hamon at 4000 ATK, Chaotic Phantasmal at 5000 and Gustav Rocket at 5000 give high end-board ATK and piercing or direct damage (Inferred from card stats)
D10 Main Deck Efficiency & Flexibility 50 Main deck has 17 singletons, 10 tech and 27 searchers, and the Sacred Beast package is only 1.4% exact-name purity, so consistency is diluted (Inferred)
D11 Extra Deck Efficiency & Coverage 58 Extra Deck is full at 15, with 8 Links and 3 Xyz split across three archetypes; several Links such as I:P Masquerena at 800 ATK are weak fillers (Inferred)
D12 Side Deck Adaptability 15 No Side Deck is registered (Side Deck size 0), so there is no post-side adaptability to score (Provisional)
D13 Matchup Coverage & Format Fit 50 Archetype share and meta data are absent (tournament data unavailable); Meta Power is null and this score is provisional (Provisional)
D14 Pilotability & Error Tolerance 45 Multi-archetype engine with Tribute-based Sacred Beast summons and several choice-dense hand effects has a high decision load (Inferred)

How the score was computed

Strategy profile: Midrange. Structural ≈ 58.6, Going First ≈ 60, Going Second ≈ 58, Meta = provisional, Tournament Reliability ≈ 52. Modifiers: Banlist exposure (-2); Engine conflict / archetype incoherence (-3); No side deck (-2). Final formula: 0.80*Structural + 0.20*TournamentReliability + ContextModifiers (Meta provisional; 0.80*58.6 + 0.20*52 = 57.3, then -7 modifiers = 50.3, rounded to 50)

Probability & combo summary

  • Opening a starter: P(≥1) ≈ 0.97 · 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 and starter access (27 searcher-text cards) gives a high chance of a live Sacred Beast Level 10 on turn 1 or 2
  • Layered interaction: 8 hand traps, Droll & Lock Bird, Lightning Storm, Harpie's Feather Duster, Illusion Gate, Sacred Beasts Combined Assault
  • High-ceiling Extra Deck bosses (Raviel 4000, Hamon 4000, Chaotic Phantasmal 5000, Gustav Rocket 5000) with direct-damage backup

Weaknesses

  • Three archetypes in one list with only 1.4% exact-name purity and no core Fiendsmith engine, so the deck name and build do not match
  • No side deck registered; the deck cannot adapt between games
  • No recorded combos or tournament data, so floor, median and matchup strength are unknown

Critical choke points

  • Sacred Beast Level 10 starter: each Level 10 Sacred Beast requires specific tribute or search conditions, and if none is reachable the deck has no first summon
  • Single-copy Extra Deck boss routes (Gustav Max, Chaotic Phantasmal, Gustav Rocket) that depend on specific materials on the field
Priority Remove Add Reason
1 One Dark World Accession or Dark Corridor-type non-engine card A side deck of 6 to 15 cards with a targeted hand trap or removal set for the expected opposing engine No side deck is registered, so the deck has no post-side plan; adding one fixes the largest structural gap
2 S:P Little Knight or Relinquished Anima (weak Link fillers) A second copy of Sacred Beasts Released or a higher-ATK Link that fits the Phantasm line Improves Extra Deck coverage and reduces dead-slot risk in the Phantasm route
3 Two off-archetype tech singletons (Card Destruction, Lightning Storm) Commit to one archetype core (Sacred Beasts plus Fiendsmith or Dark World) and raise its copy count Better engine coherence and purity; the list currently mixes three archetypes at low copy counts

Evidence & confidence

  • Verified: Legality: 55 Main, 15 Extra, 0 Side; all Limited and Semi-Limited copies within legal limits (Legal); Card text and stats resolved for all distinct cards; Usage stats: 3 of 11 core cards present (27.3%)
  • Inferred: Opening-hand probabilities from the hypergeometric table; Searcher, hand-trap and removal density from card text; Midrange primary strategy from composition and card roles
  • Provisional: Meta Power (null, no dated metagame sample); Matchup fit (D13) and 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 are absent No win-rate telemetry: going-first/second, matchup and brick rates are Inferred or Unknown No side deck registered: post-side plan cannot be evaluated Meta Power is Provisional unless a dated metagame sample is supplied
