Fiendsmith Deck #773727 — Yu-Gi-Oh! TCG

Deck — Deck Power Evaluation

Final Contextual Deck Power: 36/100 (±10 · Confidence: Low)

• Primary strategy: Combo
• Secondary strategies: Midrange, 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 extra-deck boards (Fiendsmith's Rextremende, Fiendsmith's Lacrima, Evil Twin Link monsters) converting into high-ATK end boards; the list also runs Chaos Angel, Underworld Goddess and Evil Twin's Trouble Sunny as Extra Deck payoffs.; Hand-trap and negation pressure (Ash Blossom, Ghost Belle, Ghost Ogre, Effect Veiler, Evenly Matched) that buys time for the engine on the opponent's turn.
• Turn 1 (going first): Open on Fiendsmith Engraver or Fiendsmith's Tract to reach a LIGHT Fiend starter, then Fusion/Link toward a Fiendsmith board. Legally this line is cut short by the copy-limit violations, so the plan is theoretical.
• Turn 2 (going second): Hold 2-3 hand traps (at least one hand trap in the six-card hand is very likely) and negate the opponent's first engine summon, then rebuild through Fiendsmith monsters in the GY.
• Recovery: Recursion through GY-revival effects (Fiendsmith's Sequence and Requiem are not in the list, so recovery depends on Lacrima the Crimson Tears and Fiendsmith in Paradise, plus Fabled Lurrie discard-summon).
• After siding: No Side Deck is registered (Side Deck size 0), so there is no post-side plan. The deck cannot adapt between games.

Why it scores here

The deck is scored as a system, not as an average of its card scores. The Fiendsmith core (Engraver, Tract, Lacrima and the Fusion/Link Extra Deck) has a reasonable chance of appearing early: the archetype core group hits at least once in a 5-card opening hand about 76% of the time (Inferred). Its interaction density is high, with about 20 hand-trap and tech cards and 13 negation-text cards, so the engine has a decent chance of surviving one interruption. Its end-board closing power is real (Rextremende 3000 ATK, Chaos Angel 3500, Trouble Sunny 3300, Underworld Goddess 3000). Against that, the list is illegal: Ash Blossom is over the Semi-Limited limit, and Engraver and Tract are over the Limited limit, so the normal Final formula does not apply and the score is capped low as a theoretical, structural-only read. No combo recordings exist, so the combo floor and median are text-only inferences. Archetype popularity earned no points, and no tournament or win-rate data was supplied.

Dimension scores

How the score was computed

Strategy profile: Combo. Structural ≈ 50, Going First ≈ 42, Going Second ≈ 48, Meta = provisional, Tournament Reliability ≈ 40. Modifiers: banlist exposure (-6); illegal copy-limit (-6). Final formula: No reliable metagame: 0.80*Structural + 0.20*TournamentReliability + ContextModifiers = 0.80*50 + 0.20*40 - 12 = 36; Illegal deck, so theoretical/structural-only and not a normal Final score

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 package (about 20 hand-trap/tech cards, 13 negation-text cards)
• Strong Extra Deck end-board options (Rextremende 3000, Chaos Angel 3500, Trouble Sunny 3300, Underworld Goddess 3000)
• Archetype core is present often enough (about 76% for at least one core card in a 5-card hand)

Weaknesses

• Illegal as built: three cards exceed their copy limits
• Duplicate-heavy main deck with 28 distinct names and 55 cards, with 24 level-0 spells and traps
• No Side Deck, so the deck cannot adapt between games
• No combo recordings, so the floor and median are unmeasured

Critical choke points

• Fiendsmith Engraver and Tract are the only reliable starters for the Fiendsmith engine, and both are over their Limited limit
• Without a Fusion or Link starter in hand, the Extra Deck payoffs stay dead

Recommended changes

Evidence & confidence

• Verified: Main 55, Extra 15, Side 0 counts within size rules; Ash Blossom 3 vs 2 legal, Engraver 3 vs 1 legal, Tract 2 vs 1 legal; Archetype core group P(>=1 in hand 5) = 0.7555; Extra Deck composition 11 Link, 3 Fusion, 1 Synchro
• Inferred: Consistency estimate from hypergeometric draw odds; Interaction density estimate from card-text flags; Structural dimension scores and weight profile
• Provisional: Meta Power (null) and D13 format fit, no dated metagame sample supplied
• 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/second, matchup, brick and OTK rates are Inferred or Unknown Meta Power is Provisional unless a dated metagame sample is supplied No Side Deck registered, so D12 has no post-side data
