Fiendsmith Deck #774102 — Yu-Gi-Oh! TCG

Deck — Deck Power Evaluation

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

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

Legality

Main 45 / Extra 15 / Side 0 — status under the rules at evaluation time: Illegal. 7 violation(s).

Identity & game plan

• Win condition: Fiendsmith and Mitsurugi board conversion into 2800-3200 ATK Ritual and Fusion boss monsters (Ruler of the End of the World, Nibiru, Fiendsmith's Desirae), theoretical only because the list is illegal; Link and Fusion follow-up through Fiendsmith's Sequence-style engines and Lacrima recursion
• Turn 1 (going first): Search a LIGHT Fiend or Mitsurugi starter with Fiendsmith's Tract and Engraver, then reach a Fusion or Link boss through Fiendsmith's Lacrima or Desirae
• Turn 2 (going second): Use Ash Blossom and Droll & Lock Bird to interrupt the opponent's first engine, then continue through Ritual monsters from the GY
• Recovery: Recurse Fiendsmith monsters from the GY through Engraver and Lacrima, and rebuild the board with Mitsurugi Ritual effects
• After siding: Not available: the deck runs no Side Deck, so there is no post-side plan

Why it scores here

This deck is Illegal in TCG: seven cards exceed their copy limits, so under the rubric it is capped and the 30 is a theoretical, structural-only read rather than a normal contextual score. Its structural read rests on how reliably it can reach a live Fiendsmith or Mitsurugi starter (about 0.84 for the 13 core copies in a 5-card hand, and about 0.97 for at least one of its 22 searcher-text cards) and on its interaction density (7 hand traps, 6 negation-text and 8 removal-text cards). Those strengths are offset by a low exact-archetype purity of 16.7%, a Main Deck that spreads across tech and generic cards, a mixed Extra Deck with only about four on-theme cards, and no Side Deck at all. No recorded boards exist, so combo ceiling and median output are text-only and low-confidence. The score comes from consistency, interaction and coherence measured on the system, not from averaging the card scores, and archetype popularity earned no points.

Dimension scores

How the score was computed

Strategy profile: Combo. Structural ≈ 50.5, Going First ≈ 50, Going Second ≈ 46, Meta = provisional, Tournament Reliability ≈ 40. Modifiers: banlist exposure (-8); hard-garnet and brick burden (-2). Final formula: Illegal cap applied. Structural 50.5 = sum(D x Combo weight)/100; 0.80*50.5 + 0.20*40 = 48.4; modifiers -10 gives 38.4; capped to 30 as theoretical/structural-only. Meta Power provisional (null).

Probability & combo summary

• Opening a starter: P(≥1) ≈ 0.84 · key two-card combo ≈ — · full-brick estimate ≈ 0.16 (all Inferred)
• Combo output: best PowerIndex —, median —, board-per-starter —
• Turn order: 0 going-first lines vs 0 going-second lines

Strengths

• Starter access is high: about 0.84 for at least one core starter in a 5-card hand and 0.97 for a searcher-text card
• Dense interaction: 7 hand traps, 6 negation-text and 8 removal-text cards
• Multiple recursion routes through Engraver, Lacrima and Mitsurugi GY effects

Weaknesses

• Deck is Illegal: seven cards exceed their copy limits
• Low exact-archetype purity (16.7%) with a broad tech and generic base
• No Side Deck, so no post-side adaptation
• Extra Deck mixes several unrelated archetypes and generic Link/Fusion cards

Critical choke points

• Fiendsmith Engraver is legal only once and is run three times
• Droll & Lock Bird and Fiendsmith's Lacrima are single-copy Limited cards that anchor both interaction and recursion

Recommended changes

Evidence & confidence

• Verified: Legality: seven cards exceed their copy limits; deck is Illegal; Main 45 and Extra 15 are within size rules; Side 0; Banlist statuses and legal copy limits for all restricted cards; Archetype purity 16.7% and archetype spread
• Inferred: Starter accessibility from hypergeometric estimates (about 0.84 core, 0.97 searcher); Brick and interaction-density reads from card text; Going-first and going-second estimates from hand-trap and starter probabilities; Structural score from the Combo weight profile
• Provisional: Meta Power (null, no dated metagame sample); Matchup and format-fit scores (no tournament context)
• Data gaps: No combos supplied: combo floor, median and ceiling are text-only inference No tournament link: archetype meta-share and match record absent No win-rate telemetry: going-first, going-second, matchup, brick and starter rates are Inferred or Unknown Meta Power is Provisional unless a dated metagame sample is supplied Deck title is null; no Side Deck is present Probabilities are Main Deck only and do not account for the 7 over-limit copies
