Fiendsmith Deck #773260 — Yu-Gi-Oh! OCG

Deck — Deck Power Evaluation

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

• Primary strategy: Combo
• Secondary strategies: Stun, Toolbox
• 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: Fiendsmith and Power Patron Link/Synchro boards built from the Fiendsmith Engraver and Elfnote engine, closed by Link and Synchro beaters such as Junora, Chaos Angel and Elfnote June Pride; Ars Magna and Medius/Theorealize lines that add Power Patron monsters and Link beaters to the board
• Turn 1 (going first): Open with Engraver or Elfnote Regina and Ars Magna searchers, use Fiendsmith's Tract or Medius to gather the Fiendsmith and Elfnote pieces, then Link or Synchro into a board. Illegal copy counts make this plan theoretical only.
• Turn 2 (going second): Hold Ash Blossom, Droll, Infinite Impermanence, Effect Veiler and Ghost Ogre to answer the opponent's first summons, then rebuild through Elfnote and Medius searches
• Recovery: Ghost Belle and Ghost Mourner recur monsters from the GY, Medius and Theorealize restore access to Power Patron pieces, and Fiendsmith monsters can be shuffled back from the GY
• After siding: No side deck is present (Side Deck size 0), so there is no post-side plan. Side slots are unused, which is a gap in the best-of-3 read.

Why it scores here

This list is Illegal (3 copies of Ash Blossom, which allows 2, and 3 copies of Fiendsmith Engraver, which allows 1), so the score is a structural read capped at 30 and not a normal final score. The engine is reasonably accessible: Engraver, Regina, Medius and Ars Magna searchers give about 93% searcher-text access in a 5-card hand, and the 14 hand-trap copies give about 84% at least one going second. The combo evidence is empty (no parseable boards), so the ceiling and median are text-only inference. Structural power of about 53 comes from consistency and interaction on the system, not from averaging card scores or from Fiendsmith's popularity. Side deck is absent and no meta sample exists, so matchup and post-side points stay low.

Dimension scores

How the score was computed

Strategy profile: Combo profile only; Stun weights not blended because the deck is illegal and combo data is absent. Structural ≈ 53, Going First ≈ 50, Going Second ≈ 48, Meta = provisional, Tournament Reliability ≈ 40. Modifiers: banlist exposure (-8); illegal_cap (-12). Final formula: Uncapped: 0.80*Structural(53) + 0.20*TournamentReliability(40) + Modifiers(-8) = about 42; capped at 30 because the deck is Illegal (theoretical/structural only). Meta Power is provisional.

Probability & combo summary

• Opening a starter: P(≥1) ≈ 0.65 · 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 hand-trap density (22 searcher-text, 14 hand-trap copies) gives early access and answers
• Layered Link and Synchro Extra Deck (6 Link, 7 Synchro, 2 Fusion) with several Power Patron and Fiendsmith beaters
• Multiple negation routes (Ash, Droll, Veiler, Infinite Impermanence, Ghost Ogre, Ghost Belle, Ghost Mourner)

Weaknesses

• Illegal copy counts (3 Ash Blossom, 3 Fiendsmith Engraver) make the list unplayable in OCG as built
• Off-archetype dilution: only 12.9% exact Fiendsmith copies, so engine cohesion is weak across Elfnote, Ars Magna, Mulcharmy and Power Patron
• No side deck and no combo evidence, so post-side and ceiling reads are unverifiable
• Four Limited cards in the main deck (Droll, Lucina, Engraver, Tract) plus Terminus and S:P Little Knight raise the banlist exposure

Critical choke points

• Fiendsmith Engraver is Limited and run at 3 copies; the list cannot be legal until it drops to 1
• Power Patron Link route depends on Medius/Theorealize and Ars Magna searches, which can stall if those are missing

Recommended changes

Evidence & confidence

• Verified: Illegal status: Ash Blossom 3 vs 2 copies, Fiendsmith Engraver 3 vs 1 copy (OCG banlist); Main 55 and Extra 15 within size rules; side 0; Limited banlist entries: Droll & Lock Bird, Elfnote Lucina, Fiendsmith Engraver, Fiendsmith's Tract, Prohibited Power Patron Portal - Terminus, S:P Little Knight; Archetype purity 12.9% exact Fiendsmith; usage-core list present 6 of 11 core cards
• Inferred: Opening-hand probabilities from the hypergeometric table (about 0.65 core, 0.93 searcher, 0.84 hand trap); Strategy classification as Combo with Stun secondary from the engine and hand-trap density; Interaction density and consistency reads from card text roles
• Provisional: Meta Power (null) and matchup/format fit, which need a dated metagame sample; Tournament reliability (no tournament link)
• 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 absent No win-rate telemetry (going-first/second, matchup, brick and starter rates) Meta Power provisional without a dated metagame sample Side deck absent (Side Deck size 0), so post-side plan is unverifiable
