Fiendsmith Deck #769667 — Yu-Gi-Oh! OCG

Deck — Deck Power Evaluation

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

• Primary strategy: Midrange
• Secondary strategies: Stun
• Format: ocg

Legality

Main 49 / Extra 15 / Side 0 — status under the rules at evaluation time: Illegal. 2 violation(s).

Identity & game plan

• Win condition: Link and Fusion Extra Deck threats (Evil★Twin's Trouble Sunny, Mediclius, Fiendsmith's Desirae, Fiendsmith's Lacrima) backed by Live☆Twin / Ki-sikil board presence; Fiendsmith Link recursion and Fusion Summons from the GY (Fiendsmith's Requiem, Fiendsmith's Sequence)
• Turn 1 (going first): Open a starter (Live☆Twin Ki-sikil, Lil-la or Lacrima the Crimson Tears) and Normal Summon into the Ki-sikil/Lil-la chain, search with Live☆Twin Sunny's Snitch or Secret Password, and link out to Evil★Twin monsters while holding hand traps for the opponent's turn
• Turn 2 (going second): Use the 12 hand traps (Ghost Ogre & Snow Rabbit, Ghost Belle & Haunted Mansion, Ash Blossom & Joyous Spring, Infinite Impermanence, Droll & Lock Bird, Maxx "C") to answer the opponent's first play, then convert with the Ki-sikil chain and Extra Deck Links
• Recovery: Fiendsmith's Tract and Fiendsmith Engraver search and discard recovery, Fiendsmith's Requiem and Sequence re-use from the GY, and Live☆Twin Lil-la Sweet re-summon from the GY
• After siding: Not evaluable: side_count is 0 in the export, so no side deck is recorded

Why it scores here

This list is scored as a system, not as an average of its cards, and it is capped at 35 because it is illegal: Knightmare Gryphon and D/D/D Wave High King Caesar are Forbidden in OCG and are each run once. Its structural strength (about 61 on the theoretical Midrange 70 / Stun 30 blend) comes from redundant starters spread across several engines, 12 hand traps and 13 negation-text cards that give it interaction on both turns, and a strong Extra Deck of 2,800 to 3,300 ATK Links and Fusions. The Fiendsmith label does not earn points by itself: only 7 of 57 archetype-tagged copies are exact Fiendsmith names (10.9%), and the deck mixes Live☆Twin/Ki-sikil, Evil★Twin, Unchained, and Fiendsmith cards into a multi-engine build that adds conflict and dilutes its engine. No combo boards, tournament record, or guides exist, so the combo and meta dimensions are text-only inference and the meta is provisional. The single-copy Limited engine pieces (Fiendsmith Engraver, Lacrima the Crimson Tears, Fiendsmith's Tract) are fragile choke points, and with no side deck the post-side plan is unscorable.

Dimension scores

How the score was computed

Strategy profile: 70% Midrange / 30% Stun, dimension weights blended and normalized to 100. Structural ≈ 61, Going First ≈ 62, Going Second ≈ 66, Meta = provisional, Tournament Reliability ≈ 56. Modifiers: banlist_exposure (-8); engine_conflicts (-4). Final formula: No reliable metagame, so Meta is provisional: Final = min(0.80*Structural + 0.20*TournamentReliability + ContextModifiers, 35). Illegal list, so the value is theoretical/structural-only: 0.80*61 + 0.20*56 - 12 = 48, capped at 35

Probability & combo summary

• Opening a starter: P(≥1) ≈ 0.28 · 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 that works on both turns
• Multiple independent starter routes that survive one disruption
• High-ATK Extra Deck Links and Fusions with strong closing power
• Good GY recursion and searchers for recovery

Weaknesses

• Illegal: two Forbidden cards run over the copy limit
• Multi-engine build with low exact-name archetype purity (10.9%)
• Single-copy Limited engine pieces are fragile
• No side deck recorded, so post-side play cannot be scored
• No recorded combos, tournament data, or guides

Critical choke points

• Fiendsmith Engraver (1 copy, Limited) as the Fiendsmith search and recursion engine
• Lacrima the Crimson Tears (1 copy) as the Fiendsmith starter
• Fiendsmith's Tract (1 copy, Limited) as the Fiendsmith search and Fusion route

Recommended changes

Evidence & confidence

• Verified: Main 49 / Extra 15, within the 40-60 / 0-15 size rules; Knightmare Gryphon and D/D/D Wave High King Caesar are Forbidden with 0 legal copies, each run once; All other restricted cards are at or under their limits (Limited 1, Semi-Limited Ash Blossom 2); Exact-name archetype purity 7/64 = 10.9%; Hypergeometric draw probabilities from the Main Deck
• Observed: Usage statistics show the archetype core, but its in_this_deck flags only cover the Main Deck
• Inferred: Starter redundancy and brick-rate estimates; Interaction density from the text-role scaffold; Going-second hand-trap strength; Closing-power read from ATK values; Midrange/Stun strategy classification
• Provisional: Meta Power (null) and D13 matchup/format fit; Side-deck adaptability (no side deck recorded)
• Data gaps: No combos supplied, so combo floor, median and ceiling are text-only inference No tournament link, so archetype meta-share and per-pilot record are absent No win-rate telemetry exists in YGOVN, so going-first/second and matchup signals are Inferred Meta Power is Provisional unless a dated metagame sample is supplied Side deck is 0 in the export, so post-side plan cannot be scored Usage-statistic core flags show Requiem, Sequence, Fiendsmith's Lacrima and Desirae as not in this deck, but they are on the Extra Deck list; core presence should be read as 9 of 10 by card list, not 5 of 10
