Magical Musket Deck #765862 — Yu-Gi-Oh! Master Duel

Deck — Deck Power Evaluation

Final Contextual Deck Power: 53/100 (±8 · Confidence: Medium)

• Primary strategy: Control
• Secondary strategies: Midrange, Stun
• Format: master-duel

Legality

Main 43 / Extra 15 / Side 0 — status: Legal.

Identity & game plan

• Win condition: Fiendsmith Extra Deck bosses (Rextremende, Desirae, Luce, Caesar) that land after the opponent's board has been negated or removed by hand traps and trap/spell interaction.; Magical Musket link boards (Mastermind Caspar, Max) built from Musket monsters and trap-column chains.
• Turn 1 (going first): Open with Fiendsmith's Tract or Sanct to start the Fiendsmith line, and hold Infinite Impermanence or Ash Blossom for the opponent's first play.
• Turn 2 (going second): Use the six-card hand's hand traps (Ash Blossom, Infinite Impermanence, Ghost Ogre, Effect Veiler, Maxx C) to stop the opponent's first board, then rebuild with Musket or Fiendsmith monsters.
• Recovery: Recover through GY effects: Fiendsmith Engraver from the GY, Musketeer Doc and Caspar searching Musket cards, and Fiendsmith's Lacrima recovering LIGHT Fiend monsters.
• After siding: Not applicable: Master Duel is a single game with no side deck (side_count 0).

Why it scores here

The deck reliably opens a functional plan because the archetype core is dense: at least one core card is in the opening five in about 96% of hands by the hypergeometric estimate, and the three-copy starters (Starfire, Caspar, Sanct, Tract, Ash, Impermanence, Fuwalos) each show about 32% in the opening five. It converts that into pressure through a Fiendsmith Extra Deck of 15 cards with strong boss options, but no recorded boards exist, so the ceiling and median are text-only inferences. Its strongest attribute is interaction: 11 hand traps, 14 negation-text cards and 14 removal-text cards support a 72 on endboard interaction, and the recovery engines (Engraver, Doc, Caspar, Lacrima) give it a real grind. The score is held back by engine conflict: exact-name Magical Musket purity is only 22.4%, with Fiendsmith, generic and Dominus cards sharing the 43-card main, and no side deck means no post-side adaptation. Popularity earned no points: archetype usage statistics only confirm the list is a standard build, and the score comes from consistency, interaction and recovery on the system, not from averaging card scores.

Dimension scores

How the score was computed

Strategy profile: Control. Structural ≈ 57, Going First ≈ 58, Going Second ≈ 62, Meta = provisional, Tournament Reliability ≈ 52. Modifiers: Engine conflict (-3). Final formula: 0.80*Structural + 0.20*TournamentReliability (Meta provisional); Structural 57.3, TR 52, modifiers -3 => 53

Probability & combo summary

• Opening a starter: P(≥1) ≈ 0.96 · key two-card combo ≈ — · full-brick estimate ≈ 0.04 (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 suite (11 hand traps, 14 negation-text cards)
• Redundant recovery through GY effects (Engraver, Doc, Caspar, Lacrima)
• Extra Deck with several high-ATK bosses (Luce 3500, Rextremende 3000, Desirae 2800, Caesar 2800)

Weaknesses

• Exact-name Magical Musket purity only 22.4%, so the Musket core is diluted
• No side deck in Master Duel, so no post-side adaptation
• Many reactive cards with timing demands, which raises pilot load

Critical choke points

• Fiendsmith starter (Tract or Sanct) for the Fiendsmith line
• Musket monster on field needed for Musket trap/spell activations

Recommended changes

Evidence & confidence

• Verified: Legal in Master Duel: 43 main, 15 extra, 0 side, Crossout Designator and Maxx C Limited at 1 copy each; Archetype spread: Musket 13, Fiendsmith 16, Dominus 4, generic 18; Guides describe the deck as a spell/trap control build with a Fiendsmith engine
• Observed: Archetype usage statistics show the deck's core cards are standard for the archetype (usage_statistics available)
• Inferred: Opening-hand starter probabilities (hypergeometric); Interaction density and recovery from card text; Going-second hand-trap coverage ≈ 85%
• Provisional: Meta Power (no dated meta sample); Matchup and format fit (no tournament data)
• Data gaps: No combos supplied (combos_evidence total 0), so combo floor, median and ceiling are text-only inference No win-rate telemetry for going-first, going-second, matchup or brick rate No tournament link; archetype meta-share and per-pilot record absent usage_statistics in_this_deck flags only check the Main Deck: 14 extra-deck core cards (for example Lacrima, Desirae, Requiem, Caesar) are flagged missing although they are present in the 15-card Extra Deck, so core_present_pct 44 understates true presence (25 of 25 by the Extra list) Deck title is null; no side deck exists in Master Duel Meta Power provisional unless a dated metagame sample is supplied
