Fiendsmith Deck #769498 — Yu-Gi-Oh! OCG

Deck — Deck Power Evaluation

Final Contextual Deck Power: 35/100 (±10 · Confidence: Low)

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

Legality

Main 40 / Extra 15 / Side 0 — status: Illegal. 2 violation(s).

Identity & game plan

• Win condition: Extra Deck Link and Fusion boards (Varar, Zebufera, Duralume, Desirae, Chaos Angel) that Link-summon off Vaalmonica Pendulum Zone and Fiendsmith materials; Fiendsmith Fusion/Link lines (Desirae, Sequence, Requiem) that make a single large board off the Fiendsmith core
• Turn 1 (going first): Search with Vaalmonica searchers (Scelta, Versare, Intonare, Vaalmonica Agathokakological Voice) and set a Pendulum pair, then Link-summon toward a 2500-3000 ATK Link
• Turn 2 (going second): Hold hand traps (Ash Blossom, Effect Veiler, Ghost Belle, Droll, Ghost Ogre, Infinite Impermanence) to break the opponent's first board, then rebuild through Pendulum and Link summons
• Recovery: Recurrence through Engraver, Lacrima and Vaalmonica GY effects, then re-Link from the GY using Resonance Counters
• After siding: Not assessable: the deck runs no Side Deck (side_count 0), so there is no post-side plan

Why it scores here

This list is Illegal in OCG: Fiendsmith Engraver and Fiendsmith's Tract are each run twice against a Limited limit of one, so the evaluation is theoretical and structural only and the score is capped low. The structural read is that the deck reliably opens a Vaalmonica Pendulum searcher on turn 1 (P(at least one searcher in a 5-card hand) approximately 0.96, Inferred), keeps a 10-card hand-trap suite that gives it real going-second interruption, and closes through high-ATK Link and Fusion monsters. Score is not from popularity: the archetype label 'Fiendsmith' is only 8 of 55 copies, while 23 copies are Vaalmonica, so the engine is a hybrid and the label understates it. No card scores were averaged; the system read rests on redundancy, interaction, and extra-deck threats. There is no combo data, no sideboard, and no tournament or win-rate evidence, so the ceiling and median are text-only inference.

Dimension scores

How the score was computed

Strategy profile: Midrange. Structural ≈ 58.5, Going First ≈ 60, Going Second ≈ 62, Meta = provisional, Tournament Reliability ≈ 50. Modifiers: Illegal copy-limit cap (-16); No side deck (-3); Hybrid archetype label mismatch (-2); Dependence on Limited key cards (-2). Final formula: No reliable metagame: 0.80*Structural + 0.20*TournamentReliability + modifiers = 0.80*58.5 + 0.20*50 - 6 ≈ 51; capped to 35 because the list is Illegal (theoretical/structural-only, no normal Final Contextual score)

Probability & combo summary

• Opening a starter: P(≥1) ≈ 0.96 · 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

• Redundant searchers (18 cards) make a first-turn starter likely
• Ten hand traps give real going-second interruption and multiple answers to one disruption
• High-ATK Link and Fusion finishers (Varar 3000, Chaos Angel 3500) give closing power

Weaknesses

• Illegal copy-limit violations on Engraver and Tract
• No Side Deck, so no best-of-3 adaptation
• Archetype label understates the Vaalmonica engine; the Fiendsmith core is thin at 8 copies
• High complexity across Pendulum, Link, and Fusion routes
• Many singleton and situational hand traps raise the brick risk

Critical choke points

• Pendulum Resonance Counters are needed to Link-summon the Vaalmonica Link Monsters, so a Pendulum-zone miss stalls the Link line
• Fiendsmith Fusion (Desirae, Sequence) depends on Engraver and Limited Fiend monsters that are over the copy limit as built

Recommended changes

Evidence & confidence

• Verified: Legality: Illegal, Engraver and Tract each run 2 vs a Limited limit of 1; Main 40, Extra 15, Side 0; size rules are within the OCG range; Composition: 23 Vaalmonica copies, 8 Fiendsmith copies, 10 hand traps, 18 searchers; Card stats: Varar 3000 ATK, Chaos Angel 3500 ATK, Desirae 2800 ATK
• Observed: Archetype core inclusion: Lacrima 82%, Fabled Lurrie 71%, Droll 62% (usage_statistics)
• Inferred: Opening searcher probability ≈ 0.96 from hypergeometric draw odds; Hand-trap interruption resilience from text roles; Pendulum/Link engine ceiling from card text; Going-second hand-trap plan
• Provisional: Meta Power and matchup fit (no dated metagame sample)
• 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/starter rates) usage_statistics in_this_deck flags conflict with the Extra Deck list (Requiem, Sequence, Desirae are zone extra in cards but in_this_deck false); the usage check appears to use Main Deck only Meta Power is provisional without a dated metagame sample No guides attached for the archetype
