Magistus Deck #774252 — Yu-Gi-Oh! Master Duel

Deck — Deck Power Evaluation

Final Contextual Deck Power: 56/100 (±7 · Confidence: Medium)

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

Legality

Main 40 / Extra 15 / Side 0 — status: Legal.

Identity & game plan

• Win condition: Magistus and Fairy Tail Fusion, Link and Xyz boss monsters (Zoroa the Magistus Verethragna 2900 ATK, Teller of Fairy Tails 1850 ATK, Aiwass 2000 ATK) that convert board presence into attacks; Fairy Tail monsters attacking directly (Fairy Tail Ball and Endymion Empire text), with Regulus and Verre as recurring pressure
• Turn 1 (going first): Open on a searcher (Fairy Tail Ball, Regulus, Endymion Empire, Spenta) to reach the Magistus or Fairy Tail core, while holding one hand trap for the opponent's first real play
• Turn 2 (going second): Use the six-card hand's hand traps (13 copies, P(at least one in 6) = 0.92) to answer the opponent's first board, then rebuild through searchers into a Fusion or Link boss
• Recovery: Recover through Fairy Tail monsters and Spells in the GY or banishment (Once Upon a Fairy Tail, Tails of the Fairy Tails) and Verre Magic recursion, rebuilding into the Extra Deck boss monsters
• After siding: No Side Deck is registered, so there is no post-side plan; any adaptation has to come from the Main Deck

Why it scores here

The deck opens on searcher density (17 searcher-text cards, P(at least one in a 5-card hand) = 0.95) and reaches its archetype core in most hands (13 core copies, P = 0.88), so the engine is accessible on paper, though the combo ceiling is text-only because no recorded boards exist. Its 13 hand traps give a six-card going-second hand a 0.92 chance of holding at least one answer, and the three overlapping engines (Magistus, Fairy Tail, Endymion) give it several independent routes to restart after disruption. Interaction is layered across negations, two removal-style effects and Crossout Designator, and the Extra Deck supplies high-ATK closers, but the deck has no Side Deck, so it cannot adapt after a best-of-three loss. Only 25.5% of the Main Deck uses the exact Magistus name and 41 cards are off-archetype, which lowers consistency and pilotability; the score comes from the system's consistency, interaction and closing power, not from Magistus being a popular archetype or from averaging card scores.

Dimension scores

How the score was computed

Strategy profile: Midrange. Structural ≈ 60, Going First ≈ 58, Going Second ≈ 62, Meta = provisional, Tournament Reliability ≈ 55. Modifiers: engine conflicts (-3). Final formula: 0.80*Structural(60) + 0.20*TournamentReliability(55) + ContextModifiers(-3) = 56; Meta provisional; Structural computed with D13 dropped and weights renormalized

Probability & combo summary

• Opening a starter: P(≥1) ≈ 0.95 · key two-card combo ≈ — · full-brick estimate ≈ 0.12 (all Inferred)
• Combo output: best PowerIndex —, median —, board-per-starter —
• Turn order: 0 going-first lines vs 0 going-second lines

Strengths

• Searcher density (17 cards) gives a high chance of a live opening hand
• Thirteen hand traps across three engines give redundant interaction on both turns
• Extra Deck covers Fusion, Xyz and Link with high-ATK closers
• Compact 40-card Main Deck with no garnet burden recorded

Weaknesses

• No Side Deck, so no post-side adaptation
• Only 25.5% exact-archetype purity; three engines compete for the same hand
• No recorded boards, so the combo ceiling and median are unverified
• Pilotability is demanding because of many hand-trap timing decisions

Critical choke points

• The archetype core (13 copies) being absent from the opening hand (about 12% of hands), which leaves only searchers and generic cards
• Reliance on Limited single copies (Instant Fusion, Maxx C, Fairy Tail - Snow, Crossout Designator) for part of the interaction suite

Recommended changes

Evidence & confidence

• Verified: Main Deck is 40 cards, Extra Deck 15, Side Deck 0, which is legal for master-duel; Banlist statuses: Limited x4 at 1 copy each, Semi-Limited Droll & Lock Bird at 2 copies, all compliant; Hand-trap, searcher and negation counts from card text; Archetype purity of 25.5% and 13 archetype-core copies
• Inferred: Opening-hand probabilities (hypergeometric, Main Deck only); Engine redundancy and interruption resilience from the hand-trap count; Going-second answer density; Closing power from card text and ATK values
• Provisional: Meta Power and format fit (no dated meta sample)
• Data gaps: no combos supplied, so combo floor, median and ceiling are text-only inference no tournament link, so archetype meta-share and per-pilot record are absent no win-rate telemetry exists in YGOVN, so going-first, going-second and matchup results are Unknown Meta Power is provisional unless a dated metagame sample is supplied no guides attached to the archetype no Side Deck, so post-side performance cannot be assessed
