Fiendsmith Deck #772369 — Yu-Gi-Oh! OCG

Deck — Deck Power Evaluation

Final Contextual Deck Power: 30/100 (±8 · Confidence: Low)

• Primary strategy: Midrange
• Secondary strategies: Toolbox, Tempo
• Format: ocg

Legality

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

Identity & game plan

• Win condition: Extra Deck boss monsters after Fiendsmith engine lines (Fiendsmith's Desirae, Chaos Angel, Bystial Dis Pater, Sangenpai Transcendent Dragion), with Tenpai Dragon and Bystial bodies as secondary pressure; Fusion and Synchro beatsticks through Tract/Desirae routes if Fiendsmith lines stall
• Turn 1 (going first): Open Lacrima the Crimson Tears and a searcher (Engraver, Tract, Lurrie, Phantazmay-free hands), search a Fiendsmith or Tenpai piece, then extend into a Link or Fusion boss; the list is not deterministic and no recorded boards confirm the sequence
• Turn 2 (going second): Use Droll & Lock Bird, Infinite Impermanence, Solemn Strike and Solemn Judgment to slow the opponent's first summons, then rebuild through GY recursion from Lacrima and Requiem-style effects
• Recovery: Lacrima recursion from the GY, Sangen Summoning or Sangen Kaimen searches, and Mulcharmy Fuwalos draws; the redundancy is real but relies on cards the illegal copy counts would have to remove
• After siding: Not applicable: the deck runs no Side Deck, so there is no post-side adjustment

Why it scores here

The deck reliably opens a Lacrima or searcher line only about a quarter of the time on a 5-card hand (P(at least one Lacrima) about 0.25, Inferred), so the engine is accessible but not dependable. Its interaction suite (Imperm, Droll and Lock Bird, Solemn Strike, Solemn Judgment, Harpie's Feather Duster, Raigeki) gives the end-board and going-second score most of its points. Pressure comes from several 2500 to 3500 ATK Extra Deck bosses, but the deck spreads across Tenpai Dragon, Bystial, Sangen, Mulcharmy and Fiendsmith with only 11 of 70 non-Extra copies in the exact Fiendsmith name, which holds consistency back. The deck is illegal (three copy-limit violations), so its score is structural only and capped at 30; popularity of the archetype did not earn points, and no card scores were averaged into the result.

Dimension scores

How the score was computed

Strategy profile: Midrange profile (primary) with the Toolbox skew noted in modifiers; secondary weight not applied. Structural ≈ 50, Going First ≈ 48, Going Second ≈ 52, Meta = provisional, Tournament Reliability ≈ 45. Modifiers: Banlist and copy-limit exposure (-4); Engine conflicts (-5); Illegal cap (0). Final formula: No reliable metagame: 0.80*Structural(50) + 0.20*TournamentReliability(45) = 49; modifiers -9 gives 40; capped at 30 because the list is Illegal (structural-only evaluation)

Probability & combo summary

• Opening a starter: P(≥1) ≈ 0.25 · 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

• Layered hand traps and removal (Imperm, Droll and Lock Bird, Solemn Strike, Solemn Judgment, Harpie's Feather Duster, Raigeki)
• Extra Deck bosses at 2500 to 3500 ATK with several summon routes
• Searcher density: P(at least one searcher-text card in 5) about 0.72

Weaknesses

• Illegal copy counts on three cards, including two engine searchers
• Low exact-archetype purity (15.7 percent) and conflicting sub-engines
• Heavy tech and singleton count increases brick and dead-card risk
• No side deck, so no post-side adaptation

Critical choke points

• Lacrima starter access (P about 0.25 on 5-card hands)
• Copy-limit violations must be fixed before the deck is playable as built

Recommended changes

Evidence & confidence

• Verified: Legality: 55 main, 15 extra, 0 side; three copy-limit violations (Super Polymerization 3 vs 2, Engraver 2 vs 1, Tract 2 vs 1); Exact-name archetype purity 15.7 percent; 11 of 70 non-Extra copies are exact Fiendsmith; Extra Deck breakdown: 4 Link, 4 Fusion, 6 Synchro, 1 Xyz
• Observed: Archetype usage stats available (12 rows); deck runs 5 of 11 core cards per the usage table
• Inferred: P(at least one Lacrima in 5) 0.25; searcher group 0.72 (hypergeometric, main deck only); Interaction density and going-second read from card text; Consistency and brick estimates from composition
• Provisional: Meta Power and matchup fit (no dated meta sample)
• Data gaps: No combos supplied: combo floor, median and ceiling are text-only inference No tournament link: archetype meta-share and per-pilot record absent No win-rate telemetry for going-first, going-second, matchup or brick rates Inconsistency in usage statistics: Fiendsmith's Requiem, Fiendsmith's Sequence and Fiendsmith's Desirae are listed in cards[] as Extra Deck copies, yet usage core cards marks them in this deck=false and lists them as missing core cards; the core-present percentage (45.5) is therefore likely understated and was not used to score D1 Meta Power is Provisional unless a dated metagame sample is supplied
