Magical Musket Deck #765446 — Yu-Gi-Oh! Master Duel

Deck — Deck Power Evaluation

Final Contextual Deck Power: 64/100 (±6 · Confidence: Medium)

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

Legality

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

Identity & game plan

• Win condition: Fiendsmith and link/fusion Extra Deck threats (Luce, Rextremende, Caesar, Desirae) converted after the hand-trap and backrow layer has stripped the opponent's answers or board; Magical Musket column plays (Starfire, Caspar, Doc) that re-add Musket Spell/Traps and recur material
• Turn 1 (going first): Open with Ash Blossom, Infinite Impermanence or Effect Veiler up, use Fiendsmith's Tract/Sanct to start the Fiendsmith line, and keep Musket backrow ready to answer the first summon
• Turn 2 (going second): Hold a hand trap (11 in deck, P>=1 in six cards 0.85) to stop the opponent's first board, then Dominus Spark or Purge and Musket backrow to clear the field before committing Extra Deck threats
• Recovery: Fiendsmith Engraver and Lacrima recursion from the GY, Musket Caspar searches, and Fiendsmith's Tract to rebuild the Fiendsmith monster and equip loop
• After siding: Not applicable: Master Duel decks carry no Side Deck (side 0), so there is no post-side adjustment

Why it scores here

The deck reliably opens interaction: 11 hand traps and 14 negation-text cards mean most hands have a live answer on the opponent's first play, and the core archetype cards are present in about 96% of opening five-card hands (Inferred hypergeometric estimate). Its conversion is carried by the Fiendsmith and Musket Extra Deck threats, but no recorded boards exist, so the ceiling and median are text-based inference rather than observed output. Layered backrow removal (Dominus Spark and Purge, Last Stand, Desperado, Dancing Needle) gives the board-breaking and end-board strength that earns most of the score, especially going second. The structural score comes from consistency, interaction and resilience on the system as a whole, not from averaging individual card scores. Archetype popularity and usage stats confirm the list is real but earn no points on their own, and the three-way engine split (Musket, Fiendsmith, Dominus) costs some coherence.

Dimension scores

How the score was computed

Strategy profile: Stun, meta-neutral (D13 dropped and renormalised over remaining 86 weight). Structural ≈ 67, Going First ≈ 64, Going Second ≈ 70, Meta = provisional, Tournament Reliability ≈ 66. Modifiers: engine conflict / three-way archetype split (-2); conditional dead-card risk (-1). Final formula: 0.80*Structural + 0.20*TournamentReliability + ContextModifiers (Meta provisional); 0.80*67 + 0.20*66 = 66.8, then -3 modifiers = 63.8, rounded to 64

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 interaction: 11 hand traps and 14 negation-text cards give a live answer on most turns
• Layered backrow removal (Dominus Spark, Dominus Purge, Last Stand, Desperado, Dancing Needle) for board breaking, especially going second
• High opening-hand reliability for the core archetype (P at least one in opening 5 approx 0.96)
• Compact 43-card main with 3-of starters and a 15-card Extra Deck that uses every slot
• Extra Deck top end (Luce, Rextremende, Caesar, Desirae) gives closing power once the board is clear

Weaknesses

• No recorded boards, so the combo ceiling and median are text-based inference only
• Three-way engine split (Musket, Fiendsmith, Dominus) with 22% exact-name purity weakens coherence
• Several conditional cards (Fiendsmith in Paradise, four Musket Spell/Traps) can dead-draw
• No Side Deck, so no post-side adaptation
• Heavy reliance on hand traps and backrow means low pressure when interaction is absent

Critical choke points

• A Musket monster on the field is needed for the Musket Spell/Traps; without it, several backrow answers go dead
• Fiendsmith lines need LIGHT Fiend monsters and a Level 7+ target for Fiendsmith in Paradise; losing Starfire or Caspar weakens both engines
• Extra Deck access depends on Fiendsmith GY recursion; one blown Fiendsmith monster can leave the link/fusion plan without material

Evidence & confidence

• Verified: Legal in Master Duel: 43 main (40-60), 15 extra (0-15), 0 side (0-15), no violations; Crossout Designator and Maxx C are Limited at 1 copy each, both legal; 11 hand traps, 14 negation-text cards, 14 removal-text cards, 11 searcher-text cards from the card pool; Archetype spread: Fiendsmith 16, Magical Musket 13, Dominus 4, Mulcharmy 3, generic 18; Usage statistics: 25 core cards; all 11 Main Deck core cards are present
• Observed: Deck is real and accessible: guides describe Magical Musket as a Spell/Trap control build with Fiendsmith as the third engine
• Inferred: Opening-hand consistency: P at least one archetype core card in opening 5 approx 0.96; Full-brick estimate approx 0.04, driven by 5 conditional cards; Stun primary strategy from hand-trap and negation density plus backrow removal; Ceiling and median from text only (Fiendsmith recursion, Extra link/fusion access); Going-second hand-trap coverage P at least one in six cards approx 0.85
• Provisional: Meta Power: no dated metagame sample supplied; Matchup and format fit (D13): no tournament link or meta-share context; Side Deck adaptability (D12): no Side Deck in Master Duel
• 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 exists in YGOVN; going-first/second, matchup, brick and starter rates are Inferred or Unknown Meta Power is Provisional: no dated metagame sample supplied Usage-statistics data quality: in_this_deck is false for all 14 Extra Deck core cards that this deck runs (Lacrima, Aerial Eater, Necroquip, Luce, Desirae, Caesar, Agnumday, Max, Requiem, S:P Little Knight, Sequence, Mastermind Caspar, Rextremende, Fancy Ball), so core_present_pct 44 understates the true 25 of 25; the preprocessor appears to match Main Deck only Master Duel has no Side Deck: post-side plan and D12 are not applicable Deck title is null in the export
