Fiendsmith Deck #774727 — Yu-Gi-Oh! Master Duel

Deck — Deck Power Evaluation

Final Contextual Deck Power: 53/100 (±6 · Confidence: Medium)

• Primary strategy: Control
• Secondary strategies: Combo, Toolbox
• Format: master-duel

Legality

Main 41 / Extra 15 / Side 0 — status: Legal.

Identity & game plan

• Win condition: Extra Deck boards (Fiendsmith Desirae and Fiendsmith Lacrima, plus Bystial and Chaos Angel LIGHT/DARK closers) that come online after hand traps and negations have protected the first turns; Radiant Typhoon and Bystial recursion and draw engines that keep card advantage flowing in long games
• Turn 1 (going first): Open with Engraver or Tract to reach a Fiendsmith Link or Fusion line while holding Ash, Veiler or Ghost Mourner for the opponent's first activation; the hand-trap-heavy hand can be dead if the opponent does nothing on turn 1
• Turn 2 (going second): Use the 6-card hand to hold 1-2 hand traps and 1 starter; negate or destroy the opponent's first board, then rebuild through GY-based Fiendsmith and Bystial effects
• Recovery: Recover through Fabled Lurrie and Crimson Tears from the GY, Engraver shuffle-revival, and Bystial GY banishes into a new Extra Deck summon
• After siding: No side slot in this list (side_count 0); there is no post-side plan to evaluate

Why it scores here

The score comes from the deck as a system: it can usually reach a Fiendsmith or Bystial starter by turn 2 and then has 11 hand traps and 9 negation-text cards to protect that first line, which is the main reason it rates above average. Recursion through Fabled Lurrie, Crimson Tears, Engraver and Bystial GY banishes gives it a real grind, and the Extra Deck has enough 2500 to 3500 ATK closers to finish games. The main drags are a narrow Fiendsmith engine (11 of 56 cards are named Fiendsmith, with about 45 off-archetype copies across Bystial, Radiant Typhoon and Branded), a going-first hand that can be dead against an opponent who does nothing, and no side deck, so there is no post-side plan. Popularity and the guide's Fiendsmith Control label did not earn points on their own, and no card scores were averaged into the result.

Dimension scores

How the score was computed

Strategy profile: Control. Structural ≈ 58.5, Going First ≈ 60, Going Second ≈ 65, Meta = provisional, Tournament Reliability ≈ 56.6. Modifiers: banlist_exposure (-2); engine_dilution_multi_archetype (-3); recursion_and_hand_trap_redundancy (2); weak_post_side_plan (-2). Final formula: 0.80*Structural + 0.20*TournamentReliability + ContextModifiers (Meta provisional; 0.80*58.5 + 0.20*56.6 = 58.1, then -5 modifiers = 53)

Probability & combo summary

• Opening a starter: P(≥1) ≈ 0.42 · 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

• Eleven hand traps and nine negation-text cards protect the first lines
• Recursion (Lurrie, Crimson Tears, Engraver, Bystial GY banishes) supports a long grind
• Extra Deck closers reach 2500 to 3500 ATK
• Legal list with all banlist-limited cards at legal copy counts

Weaknesses

• Narrow Fiendsmith engine: only 6 main-deck Fiendsmith cards and 45 off-archetype copies
• Going-first hands can be dead when hand traps have no opponent action to answer
• No side deck, so there is no post-side adjustment
• No recorded combos or tournament data, so ceiling and floor are inferred

Critical choke points

• Engraver and Tract (4 copies total) are the main Fiendsmith starters; P(at least one in a 5-card opener) is about 0.42
• Maxx C and Radiant Typhoon Vision are Limited, so they cannot be replaced by extra copies

Recommended changes

Evidence & confidence

• Verified: Legal status, copy limits and banlist statuses of all 56 cards; Card text and stats for all listed cards; Archetype composition counts (11 Fiendsmith, 45 off-archetype); Usage stats: Ash, Maxx C and Engraver are core cards
• Inferred: Starter probability of about 0.42 for Engraver or Tract in a 5-card opener; Hand-trap dead-card risk on going first; Interaction quality and resilience estimates; Going-first and going-second power blends
• Provisional: Meta Power (null) and matchup fit (D13); Post-side plan (D12) with no side deck; Floor and median (D4) without recorded boards
• 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 match record are absent No win-rate telemetry exists in YGOVN, so going-first and going-second splits are Inferred Meta Power is Provisional without a dated metagame sample Usage-stat core presence (63.6%) contradicts the zone listing, which puts several core Fiendsmith cards in the Extra Deck; the usage stat appears to count Main Deck only Deck title is null Side deck is empty; post-side analysis is not possible
