Fiendsmith Deck #773155 — Yu-Gi-Oh! OCG

Deck — Deck Power Evaluation

Final Contextual Deck Power: 25/100 (±10 · Confidence: Low)

• Primary strategy: Midrange
• Secondary strategies: Toolbox, Combo
• Format: ocg

Legality

Main 55 / Extra 13 / Side 0 — status under the rules at evaluation time: Illegal. 2 violation(s).

Identity & game plan

• Win condition: Sacred Beast / Phantasm boss summons (Infinity of the Sacred Beasts - Raviel, Calamity of the Sacred Beasts - Hamon, The Chaotic Phantasmal Sacred Beasts) backed by Fiendsmith and Phantasm searchers; Fiendsmith Extra Deck link and fusion pressure (Fiendsmith's Lacrima, Fiendsmith's Agnumday) and Gustav Max direct damage
• Turn 1 (going first): Search and set up a Sacred Beast engine (Martyr, Released, Thunderclap, Uria) while holding Ash Blossom and Ghost Belle to protect the first Level 10 summon
• Turn 2 (going second): Hold hand traps (Ash, Ghost Belle, Ghost Ogre, Droll and Lock Bird, Infinite Impermanence) to stop the opponent's board, then rebuild through Level 10 Sacred Beast summons
• Recovery: Recover through Sacred Beast Released, Fiendsmith's Tract, and Martyr recursion from the GY, plus Fabled Lurrie in the GY
• After siding: None: the deck runs no side deck, so there is no post-side plan

Why it scores here

The deck is Illegal in OCG as submitted: Ash Blossom & Joyous Spring is run 3 copies against a limit of 2 and Fiendsmith Engraver 2 copies against a limit of 1, so the normal Final Contextual score is capped and this evaluation is structural-only. Its size is legal (55 Main, 13 Extra, 0 Side) and the searcher density (22 searcher-text cards, about 93% to find one in an opening 5) makes the engine usually reachable on turn one. The score comes from the system: strong hand-trap and negation density (about 84% to hold a hand trap going second), big Level 10 bosses, and Fiendsmith plus Phantasm resource recursion, weighed against a split engine (only 9 exact Fiendsmith names of 68 copies, with Phantasm at 24 copies) and Level 10 bosses that are dead cards without a Sacred Beast on board. Popularity did not earn points: the archetype core is only partly present (6 of 11 core cards, 10 core copies in the Main Deck), and no card scores were averaged.

Dimension scores

How the score was computed

Strategy profile: Midrange primary, no secondary weighting applied. Structural ≈ 54, Going First ≈ 50, Going Second ≈ 60, Meta = provisional, Tournament Reliability ≈ 45. Modifiers: Banlist exposure (copy-limit violations) (-8); No side deck (-4). Final formula: Structural 53.6 -> 54; 0.80*54 + 0.20*45 = 52.2; modifiers -12 gives 40.2; Illegal cap applied (copy-limit violations), final score capped at 25 (theoretical/structural-only)

Probability & combo summary

• Opening a starter: P(≥1) ≈ 0.93 · 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 package (14 hand traps, 13 negation-text cards)
• Searchers are plentiful (22), so the engine is usually reachable
• High-ceiling Level 10 bosses (Raviel 4000, Hamon 4000, Chaotic Phantasmal 5000)
• Good GY recursion through Martyr, Released, and Fabled Lurrie

Weaknesses

• Illegal in OCG: copy-limit violations on Ash Blossom and Fiendsmith Engraver
• Split engine: only 9 exact Fiendsmith names, with 24 Phantasm copies and generic staples
• No side deck, so no post-side plan
• Level 10 bosses cannot be Normal Summoned and are dead cards without a Sacred Beast on board

Critical choke points

• Level 10 Sacred Beast summons depend on a Sacred Beast monster being on the field or in hand
• Searchers and hand traps compete for the same slots, so a hand can lack both an engine piece and interaction

Evidence & confidence

• Verified: Illegal status and copy-limit violations (Ash Blossom 3 vs 2, Fiendsmith Engraver 2 vs 1); Main 55, Extra 13, Side 0 counts and size rules; Searcher, hand-trap, and negation text counts; Archetype purity: 9 exact Fiendsmith names, 24 Phantasm
• Inferred: P(>=1 searcher in opening 5) about 0.93; P(>=1 hand trap in going-second opening 6) about 0.84; Engine split between Fiendsmith and Sacred Beast Phantasm; Interaction density and closing power from card text
• Provisional: Meta Power (no dated meta sample); Matchup and format fit (no tournament link)
• 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: going-first, going-second, matchup, and brick rates are Inferred or unknown Meta Power provisional without a dated metagame sample Deck title is null in the export
