Magistus Deck #4341 — Yu-Gi-Oh! Master Duel

Deck — Deck Power Evaluation

Final Contextual Deck Power: 36/100 (±8 · Confidence: Low)

• Primary strategy: Midrange
• Secondary strategies: Toolbox, Fusion/Synchro/Xyz/Link
• Format: master-duel

Legality

Main 40 / Extra 15 / Side 0 — status under the rules at evaluation time: Illegal. 5 violation(s).

Identity & game plan

• Win condition: Magistus Fusion, Synchro, Xyz and Link boards built from the Magistus engine (Inferred from card text; no recorded boards); Extra Deck boss monsters (Vahram, Ninaruru, Rilliona Wondrous, Aiwass) carried by equip and Spell-based interaction (Inferred)
• Turn 1 (going first): Open on a Magistus searcher or engine (Rilliona, Crowley, Zoroa, Endymion) and extend into a Fusion, Synchro or Xyz boss (Inferred; the list is illegal so the plan is theoretical)
• Turn 2 (going second): Hand traps (Ash Blossom, Effect Veiler, Infinite Impermanence, Evenly Matched) to break the opponent's first board, then Magistus engine follow-up (Inferred)
• Recovery: Magistus monsters recur from the GY through Rilliona and Crowley, and Trismagistus allows one Level 4 Spellcaster Special Summon per turn (Inferred from text)
• After siding: Not evaluable: side_count is 0, so there is no side deck and no post-side plan

Why it scores here

The list is Illegal in Master Duel: it runs 2 Called by the Grave, 2 Pot of Prosperity, and 1 each of Abyss Dweller, Crystron Halqifibrax and Number 41 Bagooska, all Forbidden, so the structural score is shown for reference and the final score is capped low and labelled theoretical only. Among the legal cards, the 3-copy Magistus engine plus Dogmatika and Endymion support gives reasonable starter density (P(at least one searcher in an opening 5) is about 0.74, Inferred). Interaction is dense (8 hand traps and 13 negation-text cards), which helps the going-second plan and end-board quality. Consistency is weakened by a low archetype purity of 38 percent, 15 tech slots, and 14 distinct Extra Deck cards with no recorded boards or win-rate data, so the combo floor and median cannot be measured. Popularity and archetype familiarity earned no points, and card scores were not averaged into the deck score.

Dimension scores

How the score was computed

Strategy profile: Midrange primary, with the Toolbox secondary acknowledged but not blended numerically. Structural ≈ 49, Going First ≈ 47, Going Second ≈ 46, Meta = provisional, Tournament Reliability ≈ 45. Modifiers: banlist exposure (-12). Final formula: 0.80*Structural + 0.20*TournamentReliability (Meta provisional), then ContextModifiers (-12); illegal-list cap applied, theoretical only

Probability & combo summary

• Opening a starter: P(≥1) ≈ 0.34 · 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

• Three-copy engine cards with high starter density (Inferred)
• Dense interaction: 8 hand traps and 13 negation-text cards (Inferred)
• Full Extra Deck with Fusion, Synchro, Xyz and Link options (Verified)

Weaknesses

• Illegal list: five Forbidden cards over the copy limit (Verified)
• Low archetype purity at 38.2 percent (Verified)
• No side deck, so no post-side plan (Verified)
• No recorded boards, so the combo floor and median are unknown (Verified)

Critical choke points

• Starter and engine access depends on a few 3-copy Magistus cards; losing them to hand traps or a single board wipe removes most of the plan (Inferred)
• The Extra Deck is full of single-copy bosses, so one disrupted Extra Deck monster can stall the board (Inferred)

Recommended changes

Evidence & confidence

• Verified: Legality: five Forbidden cards over the copy limit, status Illegal; Main 40 and Extra 15 meet the Master Duel size rules; Archetype purity 38.2 percent; Side deck is empty
• Inferred: Starter density and searcher access from the hypergeometric estimates; Interaction density from card text; Going-first and going-second plans from card text
• Provisional: Meta Power (no dated meta sample); Matchup and format fit (no tournament link)
• 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 are absent No win-rate telemetry exists for this deck (going-first, going-second, matchup, brick and OTK rates) Meta Power is Provisional without a dated metagame sample No side deck, so post-side adaptability cannot be evaluated
