Magistus Deck #773504 — Yu-Gi-Oh! Master Duel

Deck — Deck Power Evaluation

Final Contextual Deck Power: 24/100 (±6 · Confidence: Medium)

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

Legality

Main 41 / Extra 11 / Side 0 — status: Legal.

Identity & game plan

• Win condition: Level 4 Xyz line into a boss (Number C104 / Number 104: Masquerade / Outer Entity Nyarla / Gaia Dragon), with Summoner Monk or Royal Magical Library as the Level 4 starters; Endymion Pendulum burst (2800 ATK) and Bamboo Sword direct-attack pressure, both dependent on having a monster on the field
• Turn 1 (going first): T1: draw a Level 4 monster (Summoner Monk, Royal Magical Library, Magical Abductor or Verre), then Normal Summon and Xyz Summon a Level 4 boss with a second Level 4 monster; spells fill the gaps (Inferred)
• Turn 2 (going second): Not defined by the evidence: no hand traps, no floodgates, no side deck, and the Xyz boss line is the only interaction route (Inferred)
• Recovery: Draw spells (Upstart Goblin, Into the Void, Royal Magical Library counters, Wonder Wand) and Spell Power Mastery to search Endymion; recovery depends on monsters being drawn (Inferred)
• After siding: None: the deck runs 0 Side Deck cards, so there is no post-side plan

Why it scores here

The deck is legal and correctly sized, but as a system it is incoherent: 31 of 41 Main Deck cards are Spells and only 10 are monsters, and the list contains no Magistus monsters at all, so the Magistus, Trismagistus and Verre Magic Spells have nothing to act on. Its consistency depends on drawing one of the 8 Level 4 monsters, which gives about a 77% chance of at least one monster in a 5-card opening hand and roughly a 23% chance of a hand with no monster (Inferred). Its ceiling is a Level 4 Xyz boss such as Number C104 or Nyarla, with the Bamboo Sword and Endymion lines as secondary pressure. The score comes from consistency, a moderate ceiling, and the Xyz boss-plus-negate interaction on the system; it does not come from Magistus being a popular archetype (7.7% exact-name purity, 1 of 25 core cards present), and the individual card scores were not averaged. The two Synchro Monsters and the Fusion Monster appear non-functional with the Main Deck as listed (no Tuner or Dark Magician visible; Inferred), and there is no Side Deck to adapt.

Dimension scores

How the score was computed

Strategy profile: Combo. Structural ≈ 32, Going First ≈ 32, Going Second ≈ 27, Meta = provisional, Tournament Reliability ≈ 25. Modifiers: engine conflicts (-4); weak or absent post-side plan (-2). Final formula: 0.80*Structural(31.7) + 0.20*TournamentReliability(25) + ContextModifiers(-6) = 24.4 -> 24 (Meta provisional)

Probability & combo summary

• Opening a starter: P(≥1) ≈ 0.77 · key two-card combo ≈ — · full-brick estimate ≈ 0.23 (all Inferred)
• Combo output: best PowerIndex —, median —, board-per-starter —
• Turn order: 0 going-first lines vs 0 going-second lines

Strengths

• Legal, fully sized Main Deck (41) and Extra Deck (11) with the one Limited card (Foolish Burial Goods) at 1 copy
• Eight Level 4 monsters in the Main Deck feed several Level 4 Xyz bosses from the Extra Deck
• Draw density: Upstart Goblin, Into the Void, Wonder Wand, Golden Bamboo Sword and Royal Magical Library counters
• Number C104 provides a negate plus Spell/Trap destruction, and it hits 3000 ATK

Weaknesses

• 31 Spells against 10 monsters: the Spells need monsters to act, and the deck has few monsters to act with
• No Magistus monsters in the Main Deck, so the Magistus Spells (Trismagistus, Magia Magic, Verre Magic) are largely dead
• Two Synchro Monsters and the Fusion Monster look unplayable without a Tuner or Dark Magician (Inferred)
• No Side Deck and no hand traps or floodgates
• Off-archetype spread across 7+ sub-archetypes (7.7% exact-name purity)

Critical choke points

• Drawing a monster in the opening hand (about 77% with 5 cards)
• A Level 4 monster pair to Xyz Summon the boss
• Number C104 / Number 104 as the single negate line, and both need an Xyz on the field

Recommended changes

Evidence & confidence

• Verified: Deck is legal under BanMasterDuel with 41 Main, 11 Extra, 0 Side; Foolish Burial Goods is Limited with 1 copy run; Magistus exact-name purity 7.7%; 1 of 25 core cards present; No tournament or combo records exist
• Inferred: Probability of at least one monster in an opening hand (0.77 going first); Brick rate of about 0.23 for a no-monster opening hand; Synchro and Fusion summons are non-functional with the listed Main Deck; Level 4 Xyz line is the realistic conversion path
• Provisional: Meta Power and matchup fit: no dated metagame sample
• Data gaps: no combos supplied: combo floor, median and ceiling are text-only inference no tournament link: archetype meta-share and per-pilot record absent no win-rate telemetry (going-first/second, matchup, brick and starter rates) Meta Power is provisional without a dated metagame sample Tuner status and Dark Magician presence are inferred from type and name, not confirmed from full card text
