Fiendsmith Deck #762743 — Yu-Gi-Oh! Master Duel

Deck — Deck Power Evaluation

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

• Primary strategy: Midrange
• Secondary strategies: Toolbox, Tempo
• Format: master-duel

Legality

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

Identity & game plan

• Win condition: Dragonmaid Fusion boards (Dragonmaid Sheou, House Dragonmaid) backed by 3500/3000 ATK bodies and Dragon-based recursion; Link and Xyz pressure (Fiendsmith's Lacrima, The Zombie Vampire) once the board is established
• Turn 1 (going first): Turn 1 Dragonmaid search or Normal Summon into a Dragonmaid Spell/Trap (Hospitality or Tidying) for board presence; hold Ash Blossom for the opponent's first activation
• Turn 2 (going second): Hand trap (Ash Blossom x2) on the opponent's opening starter, then a Fusion or Link line through Dragonmaid recursion
• Recovery: Return Dragonmaid monsters to hand at the Battle Phase (Chamber, Nurse, Parlor, Kitchen) and reuse them for later summons and searches
• After siding: Not applicable: Master Duel has no Side Deck in this list (side 0); adaptation is limited to in-deck flex choices

Why it scores here

The deck is a Dragonmaid-based midrange shell: 27 of 41 Main Deck copies are Dragonmaid, with 5 Bystial and 7 Fiendsmith cards, so its exact Fiendsmith purity is only 12.5% even though the listed archetype is Fiendsmith. It opens functional plans through a dense searcher suite (13 searcher-text cards, P(at least one in a 5-card opening hand) about 0.87) but the three-copy starters have only about a 0.33 chance of appearing in an opening hand, which caps D1 and D2. Interaction is the strongest system trait: two Ash Blossom, Triple Tactics Talent, Raigeki, Bystial Magnamhut and Dragonmaid Sheou negation give layered answers (D7 66), and Dragonmaid recursion keeps the deck playing after disruption (D5 58, D6 62). Popularity and the archetype label did not earn points, and no card scores were averaged; the score comes from consistency, interaction and resource recovery on the system. No recorded boards, win rates or tournament data exist, so combo ceiling and floor are text-based inferences and the score is capped by that gap.

Dimension scores

How the score was computed

Strategy profile: Midrange primary, Toolbox secondary (structural weights from the Midrange profile). Structural ≈ 57, Going First ≈ 58, Going Second ≈ 56, Meta = provisional, Tournament Reliability ≈ 52. Modifiers: engine_conflict (-2); banlist_exposure (-1). Final formula: 0.80*Structural + 0.20*TournamentReliability + ContextModifiers (Meta provisional, no dated metagame sample)

Probability & combo summary

• Opening a starter: P(≥1) ≈ 0.33 · 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 searcher suite (13 searcher-text cards) keeps early plans accessible
• Layered interaction: two Ash Blossom, Triple Tactics Talent, Raigeki, Bystial Magnamhut and Sheou negation
• Dragonmaid recursion gives repeatable value across turns
• Fusion boards with 3500 and 3000 ATK bodies close games

Weaknesses

• Only 12.5% exact Fiendsmith purity, so the archetype label overstates engine cohesion
• Three-copy Dragonmaid starters are not reliably live in the opening hand
• No recorded combo data, so the ceiling and median are unmeasured
• 16 singleton slots dilute the core engine

Critical choke points

• Dragonmaid starter access in the opening hand (about 0.33 at hand 5)
• Fusion Extra Deck access for the main closing lines

Recommended changes

Evidence & confidence

• Verified: Main Deck 41 cards, Extra Deck 15, no violations, status Legal (master-duel ban field); Bystial Magnamhut is Limited at 1 copy (legal_copies 1, copies_run 1); Dragonmaid archetype spread 27 of 41 Main Deck copies; exact Fiendsmith purity 12.5%; Card text for Sheou, House Dragonmaid, Ash Blossom and Raigeki as supplied in the evidence
• Inferred: Starter P(at least one in hand 5) about 0.33 for three-copy Dragonmaid starters, and about 0.87 for any of 13 searchers; Interaction layering and recursion resilience from card-text reads; Going-first and going-second strength from text, not measured splits; Fusion closing pressure depends on Extra Deck access
• Provisional: Meta Power (null, no dated metagame sample); Matchup fit and tournament reliability (no tournament link or match record); Side adaptability (Master Duel has no side deck)
• 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/starter rates) exists in YGOVN Meta Power is provisional unless a dated metagame sample is supplied Side deck absent in Master Duel, so D12 relies on the in-deck flex only
