Fiendsmith Deck #762676 — Yu-Gi-Oh! Master Duel

Deck — Deck Power Evaluation

Final Contextual Deck Power: 32/100 (±8 · Confidence: Low)

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

Legality

Main 40 / Extra 15 / Side 0 — status: Illegal. 1 violation(s).

Identity & game plan

• Win condition: Fiendsmith Fusion/Link pressure and Mitsurugi Ritual boards (Ame no Murakumo no Mitsurugi 3200 ATK) after disruption; no recorded lines to confirm which is the real finisher; Zoodiac Xyz boards and Utopic Draco Future (3000 ATK) when the Extra Deck is accessible
• Turn 1 (going first): Turn 1 disruption (Ash Blossom, Droll & Lock Bird, Maxx "C") and searches via Fiendsmith's Tract / Mitsurugi Prayers; no verified opening sequence
• Turn 2 (going second): Hand traps (6 copies) and Droll & Lock Bird on the opponent's searches, then rebuild via Mitsurugi and Fiendsmith searchers
• Recovery: Searchers (20 copies) and GY recursion from Fiendsmith Engraver, Lacrima and Mitsurugi Ritual effects
• After siding: Not applicable: the deck has no Side Deck (side_count 0)

Why it scores here

The deck is illegal as built: three copies of Radiant Typhoon Eldam against a Master Duel limit of two, so it receives a capped, structural-only score rather than a normal Final Contextual score. Its interaction shell is the real strength: six hand traps, Maxx "C", Droll & Lock Bird, Ramram and Great Purification give it layered disruption, and the guide describes this as a disruption-then-grind control plan. The engine is weak, however: the list spreads across four archetypes (Mitsurugi 10, Zoodiac 10, Radiant Typhoon 8, Fiendsmith 7, exact-name purity 12.7%), so the Fiendsmith Extra Deck cards have little main-deck support, and several Extra Deck Xyz and Link monsters (Utopic Draco, S:P Little Knight, Moon of the Closed Heaven) have no clear route. The score comes from consistency and interaction on the system, not from the Fiendsmith archetype being popular or from averaging card scores, and the deck has no recorded boards or Side Deck to lift it further. (Inferred from card text and hypergeometric estimates; no win-rate data.)

Dimension scores

How the score was computed

Strategy profile: Control. Structural ≈ 46, Going First ≈ 42, Going Second ≈ 50, Meta = provisional, Tournament Reliability ≈ 38. Modifiers: Illegal copy-limit violation (Radiant Typhoon Eldam x3, limit 2) (-8); Engine conflict across four archetypes (-4). Final formula: Illegal deck: capped structural-only. Pre-cap 0.80*46 + 0.20*38 = 44.4, then modifiers -12 gives 32 (Meta provisional, not a normal Final Contextual score)

Probability & combo summary

• Opening a starter: P(≥1) ≈ 0.9 · 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

• Six hand traps plus Maxx "C" and Droll & Lock Bird give layered turn-1 and going-second disruption
• 20 searchers (Verified count) give high probability of finding a live piece each turn
• Negate and removal text is spread across main and Extra cards, so interaction is not a single point of failure

Weaknesses

• Illegal copy count: three Radiant Typhoon Eldam against a limit of two
• Four archetypes compete for slots, so exact-name Fiendsmith purity is 12.7%
• No Side Deck and no recorded boards to check the plan against
• Several Extra Deck Xyz and Link monsters have no clear route into this list

Critical choke points

• Radiant Typhoon Eldam over the copy limit: the list cannot be played legally as built until one copy is removed
• Fiendsmith Extra Deck access depends on a small number of Fiendsmith Main Deck cards (Engraver, Tract, Lacrima, Lurrie)

Recommended changes

Evidence & confidence

• Verified: Illegal status: Radiant Typhoon Eldam at 3 copies against a Master Duel limit of 2; Main 40 / Extra 15 / Side 0 counts; Archetype purity 12.7%; 20 searcher-text cards; 6 hand traps; Guide describes a disruption-then-grind control plan
• Inferred: P(>=1 Ash Blossom in 5) 0.34; P(>=1 hand trap in 6 going second) 0.65; Control reading of the deck, from the guide and card text; Interaction breadth and resilience from text
• Provisional: Meta position and matchup fit (no dated meta sample)
• Data gaps: Radiant Typhoon Eldam is over the copy limit: the list is Illegal, so the score is capped No combos supplied: combo floor, median and ceiling are text-only inference No tournament link: archetype meta-share and per-pilot record are absent No win-rate telemetry (going-first/second, matchup, brick and starter rates) exists in YGOVN No Side Deck (side_count 0), so D12 has no post-side data Meta Power is Provisional unless a dated metagame sample is supplied
