Fiendsmith Deck #774146 — Yu-Gi-Oh! TCG

Deck — Deck Power Evaluation

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

• Primary strategy: Midrange
• Secondary strategies: Stun, Toolbox
• Format: tcg

Legality

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

Identity & game plan

• Win condition: Fiendsmith Fusion/Link pressure from Engraver and Tract searches into Rextremende, Lacrima and Desirae, with Link boards (Trouble Sunny, Underworld Goddess) as the closer; Live Twin / Evil Twin Link chain from Ki-sikil and Lil-la starters
• Turn 1 (going first): Open a Fiendsmith Fiend or Live Twin starter, search with Engraver or Tract (illegal copy counts aside), and link into an end-board backed by Ash, Ghost Ogre, Ghost Belle and Effect Veiler
• Turn 2 (going second): Use the 94% hand-trap density to negate the opponent's first board, then rebuild through Link Summons from the GY
• Recovery: Recursion through Fiendsmith GY effects (Lacrima, Requiem, Sequence) and Ki-sikil/Lil-la GY revival
• After siding: Not available: the deck runs no side cards, so no post-side plan exists in the evidence

Why it scores here

The deck's score is set by its system, not by averaging its cards: the 13-copy Fiendsmith and Live Twin core is live in about 76% of five-card openings (Inferred), and the 20 hand-trap cards give about 94% at least one going-second hand-trap draw. Its Link and Fusion finishers (Rextremende, Trouble Sunny, Underworld Goddess, Desirae) give real closing power, but the recorded combo evidence is absent, so ceiling and median are text-only inference. Its brick rate is high: 24 level-0 spell and trap cards, 20 hand-traps and 22 tech slots compete for the same five-card opening. The deck is illegal as built, with three copy-limit violations (Ash Blossom, Engraver, Tract), so the score is capped and labelled theoretical and structural only. Popularity of the Fiendsmith archetype was not credited, and no side deck exists, so post-side strength earns nothing.

Dimension scores

How the score was computed

Strategy profile: Midrange. Structural ≈ 55, Going First ≈ 58, Going Second ≈ 68, Meta = provisional, Tournament Reliability ≈ 45. Modifiers: banlist exposure (-8); no side deck (-4). Final formula: Raw: 0.80*Structural(55) + 0.20*TournamentReliability(45) = 53; modifiers -12 gives 41; Illegal-list cap applied to 35 (theoretical/structural only). Meta provisional.

Probability & combo summary

• Opening a starter: P(≥1) ≈ 0.76 · 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 hand-trap and negation suite (20 hand-traps, 13 negation-text cards)
• Strong Link and Fusion closers with 3000+ ATK
• High going-second hand-trap density (94.4% at least one in six cards)

Weaknesses

• Illegal copy counts on Engraver, Tract and Ash Blossom
• Zero side deck, so no post-side plan
• High dead-card load from 24 level-0 spell/trap and 20 hand-trap slots
• No recorded combo or win-rate evidence

Critical choke points

• Engraver and Tract, the Fiendsmith searchers, are both over the copy limit and are the main engine starters
• Fiendsmith Extra Deck Link and Fusion summons depend on a single LIGHT Fiend material base

Recommended changes

Evidence & confidence

• Verified: Legality: 55 Main, 15 Extra, 0 Side; three copy-limit violations (Ash Blossom 3/2, Engraver 3/1, Tract 2/1); Banlist statuses for Droll & Lock Bird, Lacrima, Harpie's Feather Duster, S:P Little Knight and the three violations; Card text and ATK/DEF for all listed cards; Archetype core presence: 13 copies, P(at least one in 5) = 0.7555
• Inferred: Consistency and brick estimates from the hypergeometric model; Going-first and going-second estimates from hand-trap and starter densities; Closing power from Link and Fusion ATK values and text; Interaction quality from negation and removal text
• Provisional: Meta Power (null) and matchup fit (D13); Tournament reliability inputs, since no tournament link or win-rate telemetry exists
• Data gaps: Legal copy violations make the list Illegal, so the score is structural and theoretical only No combos supplied: combo floor, median and ceiling are text-only inference No tournament link: archetype meta-share and pilot record absent No win-rate telemetry (going-first/second, matchup, brick and starter rates) No side deck, so post-side adaptability cannot be measured Evidence inconsistency: usage_statistics marks Fiendsmith's Requiem, Sequence and Desirae as in_this_deck = false, yet the cards array lists each one in the Extra zone with copies = 1; the usage join needs checking Meta Power is Provisional unless a dated metagame sample is supplied
