Fiendsmith Deck #773269 — Yu-Gi-Oh! OCG

Deck — Deck Power Evaluation

Final Contextual Deck Power: 30/100 (±10 · Confidence: Low)

• Primary strategy: Midrange
• Secondary strategies: Toolbox, Fusion/Link/Xyz mechanic-heavy
• Format: ocg

Legality

Main 45 / Extra 18 / Side 0 — status under the rules at evaluation time: Illegal. 2 violation(s).

Identity & game plan

• Win condition: Fiendsmith Fusion and Link boards (Rextremende, Lacrima, Desirae, Azamina, Saint Azamina) backed by Regenesis and Mulcharmy disruption and draw; Max Metalmorph routes into Red-Eyes Black Fullmetal Dragon and Metalzoa X, plus 3000-ATK XYZ and Link closers
• Turn 1 (going first): Search Fiendsmith or Regenesis pieces with Engraver, Tract and Regenesis, then go to a Fusion or Link extension; Ash Blossom and Infinite Impermanence protect the first engine piece
• Turn 2 (going second): Open Ash Blossom, Maxx C and Mulcharmy draw effects, use hand traps to break the opponent's first summon, then rebuild the Regenesis board
• Recovery: Recycle Fiendsmith and Regenesis monsters from the GY with Lacrima, Engraver and Regenesis Code; Mulcharmy draws refill the hand
• After siding: Not evaluable: the deck has no Side Deck, so there is no post-side plan

Why it scores here

This list is Illegal: the Extra Deck holds 18 cards against an OCG maximum of 15, so it receives a theoretical, structural-only read capped at 30 rather than a normal Final score. The copy limits themselves are respected (Limited and Semi-Limited cards each run within their allowed copies). Engine access is decent: the searcher text count is high (16 cards) and about 64 percent of the core-group hands open at least one core card, both Inferred from hypergeometric estimates. The deck's weakness is that it runs several competing engines (Fiendsmith, Regenesis, Mulcharmy, Metalmorph and Red-Eyes), with only 11 of 45 main-deck copies in the exact archetype name, so conversion and consistency suffer, and it has no Side Deck. Its closing power is high because the Extra Deck contains several 3000-plus ATK boss monsters. No combo boards were recorded, and popularity or archetype usage did not earn points; the score comes from the system's consistency, interaction and closing power, not from averaging card scores.

Dimension scores

How the score was computed

Strategy profile: Midrange. Structural ≈ 49, Going First ≈ 46, Going Second ≈ 48, Meta = provisional, Tournament Reliability ≈ 42. Modifiers: Illegal size cap (-7); Engine conflicts (-5); No Side Deck (-3); Banlist exposure (-2). Final formula: Illegal deck: theoretical structural-only read. Structural 49.3 (Midrange); unconstrained 0.80*Structural + 0.20*TournamentReliability = 47.8 with modifiers -10 gives 37.8, capped to 30 for illegal size; Meta provisional

Probability & combo summary

• Opening a starter: P(≥1) ≈ 0.64 · key two-card combo ≈ — · full-brick estimate ≈ 0.36 (all Inferred)
• Combo output: best PowerIndex —, median —, board-per-starter —
• Turn order: 0 going-first lines vs 0 going-second lines

Strengths

• Strong closers in the Extra Deck (3000-plus ATK bosses)
• Searcher density (16 text hits) keeps the engine findable
• Layered interaction: 2 Ash Blossom, 2 Infinite Impermanence, Maxx C, Crossout Designator

Weaknesses

• Illegal: Extra Deck over the OCG limit by 3
• No Side Deck
• Multiple competing engines dilute consistency
• No recorded combo boards to confirm conversion

Critical choke points

• Max Metalmorph (2 copies) gates Red-Eyes Black Fullmetal Dragon and Metalzoa X
• Core Fiendsmith Fusion pieces are Limited (1 copy each)
• Regenesis and Fiendsmith starters are split across engines

Recommended changes

Evidence & confidence

• Verified: Extra Deck is 18 cards against an OCG maximum of 15; Copy limits respected for all Limited and Semi-Limited cards; Side Deck is empty; Exact-archetype purity 17.5 percent (11 of 63 archetype-linked copies)
• Observed: Usage stats: core Fiendsmith cards Sequence, Requiem and Lacrima are absent from this list; present core inclusion is 45.5 percent
• Inferred: Hypergeometric opening-hand estimates for the core group (0.64 at least one); Consistency and brick rate from card text and composition; Interaction density from role tags and negation or removal text
• Provisional: Meta Power is null; no dated metagame sample and no tournament link; D13 matchup and format fit
• 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 in YGOVN for this deck Meta Power provisional without a dated metagame sample Deck title is null Side Deck is empty, so post-side play cannot be evaluated
