Magistus Deck #9868 — Yu-Gi-Oh! Master Duel

Deck — Deck Power Evaluation

Final Contextual Deck Power: 30/100 (±8 · Confidence: Low)

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

Legality

Main 40 / Extra 14 / Side 0 — status under the rules at evaluation time: Illegal. 5 violation(s).

Identity & game plan

• Win condition: Magistus Synchro/Xyz/Fusion boards (Vahram, Zoroa, Ninaruru, Aiwass) backed by Magistus equip-based pressure (Inferred); Endymion and Dogmatika follow-up lines through Extra Deck summons (Inferred)
• Turn 1 (going first): Searcher (Endymion/Rilliona/Spell Power Mastery) into a Magistus Level 4 extender; hand traps held for the opponent's first summon (Inferred)
• Turn 2 (going second): Hand traps (Ash Blossom, Effect Veiler, Infinite Impermanence, Maxx "C", Nibiru) to break the opponent's first board, then rebuild through Magistus recursion (Inferred)
• Recovery: Magistus Vritra and Trismagistus recur Level 4 Magistus monsters from the GY; Rilliona can return banished Level 4 Spellcasters (Inferred)
• After siding: Not evaluable: the deck has zero Side Deck cards

Why it scores here

The score is set on the deck as a system, not as an average of its cards. The Magistus engine is accessible: a 1-copy searcher (Spell Power Mastery, Rilliona, Endymion) is in hand in about 78% of 5-card openings, and the Extra Deck gives several boards. The list is split across Magistus, Endymion, Dogmatika, Crystron and Frog pieces, with only 39% exact-name purity, so engine coherence is weak. Interaction is dense (about 14 negation and 16 removal text effects, 9 hand traps), which lifts end-board quality, but this is text-only inference because the deck has no recorded boards. Popularity and archetype share earned no points, since no tournament data exists. The deck is illegal in Master Duel (three restricted cards over their copy limits, three Forbidden or Limited cards), so the score is capped at 30 and labelled theoretical/structural-only. The deck has no Side Deck, so post-side adaptability is scored at the floor.

Dimension scores

How the score was computed

Strategy profile: Midrange. Structural ≈ 47, Going First ≈ 42, Going Second ≈ 50, Meta = provisional, Tournament Reliability ≈ 38. Modifiers: banlist exposure (-8); copy-limit violations (-4); engine conflicts (0). Final formula: No reliable metagame: 0.80*Structural(46.6) + 0.20*TournamentReliability(38) = 44.9, then modifiers -12 gives 32.9; capped at 30 because legality is Illegal (theoretical/structural-only)

Probability & combo summary

• Opening a starter: P(≥1) ≈ 0.78 · 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 hand-trap and negation suite (Ash Blossom, Effect Veiler, Infinite Impermanence, Maxx "C", Nibiru)
• Searcher density gives about 78% chance of a searcher in the opening hand
• Recursion through Magistus Vritra and Trismagistus gives some resilience

Weaknesses

• Illegal under Master Duel rules: three restricted cards are over their copy limit or Forbidden
• Only 39% exact-name Magistus purity; 33 off-archetype copies weaken engine coherence
• No Side Deck, so no post-side adaptation
• No recorded combos or win data, so ceiling and median are unverified

Critical choke points

• Legal fix depends on removing Called by the Grave, Crystron Halqifibrax, Toadally Awesome, and cutting Maxx "C" and Crossout Designator to 1 copy
• Magistus Extra Deck summons depend on Level 4 Spellcasters, which is a narrow set

Recommended changes

Evidence & confidence

• Verified: Illegal status: Called by the Grave (2), Crystron Halqifibrax (1), Toadally Awesome (1) are Forbidden; Maxx "C" (3) and Crossout Designator (3) exceed their Limited cap of 1; Main 40 and Extra 14 are within Master Duel size rules; Side Deck is 0; Exact-name purity 38.9%; 21 of 54 copies are Magistus; Searcher group P(>=1 in hand 5) = 0.7834; hand-trap group P(>=1 in hand 6) = 0.8082
• Inferred: Engine accessibility and brick rate (from hypergeometric odds and copy histogram); Interaction density and going-second strength (from hand-trap and negation text); Closing power from Extra Deck ATK values
• Provisional: Meta Power is null; no dated metagame sample exists; Matchup fit (D13) and tournament reliability are provisional
• Data gaps: No combos supplied; ceiling and median are text-only inference No tournament link; archetype meta-share and per-pilot records are absent No win-rate telemetry for Master Duel; going-first/second split is inferred Meta Power is provisional unless a dated metagame sample is supplied Deck title is null, so the list is identified only by its archetype and id
