Fiendsmith Deck #754403 — Yu-Gi-Oh! TCG

Deck — Deck Power Evaluation

Final Contextual Deck Power: 20/100 (±8 · Confidence: Low)

• Primary strategy: Toolbox
• Secondary strategies: Combo
• Format: tcg

Legality

Main 54 / Extra 16 / Side 0 — status: Illegal. 5 violation(s).

Identity & game plan

• Win condition: Fiendsmith and Yummy Extra Deck Link/Fusion/Synchro boards, with Fiendsmith's Desirae and Fiendsmith's Lacrima as the main boss-level bodies (Inferred from card text; no recorded boards); Interaction-led attrition using the 19 hand-trap and 16 negation-text cards (Inferred)
• Turn 1 (going first): Open a Yummy or Fiendsmith starter, search with Fiendsmith's Tract or Yummy searchers, and extend into a Link or Synchro monster (Inferred; no recorded lines)
• Turn 2 (going second): Use hand traps (Ash Blossom, Ghost Belle, Effect Veiler, Droll & Lock Bird) to stop the opponent's first summon, then rebuild with Fiendsmith or Yummy monsters (Inferred)
• Recovery: Recover through Fiendsmith Engraver and Lacrima's GY effects, and Mulcharmy draw effects when the hand is empty (Inferred from text)
• After siding: Not evaluable: the deck has no side deck (side count 0)

Why it scores here

The deck is Illegal: four cards exceed their copy limits (including a Forbidden Reprodocus) and the Extra Deck holds 16 cards against a 15-card cap, so it does not receive a normal contextual score and is capped at 20 as a theoretical, structural-only read. Its archetype purity is low (11.4% exact Fiendsmith names, with 18 Yummy and 6 Mulcharmy copies plus 27 generic cards), so the engine is split across several sub-archetypes rather than one coherent plan. The strongest part of the system is interaction: 19 hand traps and 16 negation-text cards give high going-second disruption, but no recorded boards exist, so combo ceiling and median output are text-only inference and score in the 35–40 range. Popularity and archetype usage stats confirm the list is a real, accessible build but did not add points, and the score was not produced by averaging card scores.

Dimension scores

How the score was computed

Strategy profile: Toolbox. Structural ≈ 45, Going First ≈ 40, Going Second ≈ 55, Meta = provisional, Tournament Reliability ≈ 35. Modifiers: Illegal list (-15); Banlist exposure (-8). Final formula: Structural 45 with Toolbox weights; 0.80*45 + 0.20*35 = 43 before modifiers; Illegal cap applied via modifiers to 20 (theoretical, structural-only)

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

• 19 hand traps and 16 negation-text cards give strong going-second disruption
• Layered interaction with Ash Blossom, Ghost Belle, Effect Veiler and Droll & Lock Bird
• Fiendsmith Desirae and Lacrima give strong closing bodies

Weaknesses

• Illegal list: copy-limit and Extra Deck size violations
• Very low exact-archetype purity (11.4%) with a split Yummy/Mulcharmy/Fiendsmith engine
• No recorded boards, so the combo ceiling and median are unknown
• No side deck

Critical choke points

• Fiendsmith Engraver and Lacrima as the sole engine enablers
• Limited-status copies of Marshmao, Engraver and Tract constrain legal builds

Recommended changes

Evidence & confidence

• Verified: Four copy-limit violations (Marshmao, Ash Blossom, Engraver, Reprodocus); Extra Deck of 16 exceeds the 15 cap; Exact-name archetype purity 11.4%; Main 54 / Extra 16 / Side 0 counts
• Inferred: Starter consistency ≈ 0.76 for the archetype core; Going-second hand-trap coverage ≈ 0.94; Interaction-led plan and ceiling read from card text
• Provisional: Meta and matchup fit (D13) without a dated sample
• Data gaps: No combos supplied, so floor, median and ceiling are text-only inference No tournament link, so archetype meta-share and match record are absent No win-rate telemetry exists for this deck Meta power is provisional without a dated metagame sample
