Exosister Deck #765869 — Yu-Gi-Oh! Master Duel

Deck — Deck Power Evaluation

Final Contextual Deck Power: 55/100 (±10 · Confidence: Low)

• Primary strategy: Midrange
• Secondary strategies: Tempo, Xyz, Graveyard-centric
• Format: master-duel

Legality

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

Identity & game plan

• Win condition: Exosister Xyz beaters (Exosisters Magnifica double attack, Karmael, Mikailis) built from Level 4 Exosister monsters; Exosister Gibrine and Asophiel grind-lock the opponent's GY and Special Summon access while Exosister monsters keep recurring
• Turn 1 (going first): Open on an Exosister Level 4 starter (Elis or Martha), use Betrayal or Pax to search a second Exosister, and Xyz Summon from the Extra Deck
• Turn 2 (going second): Hand-trap the opponent's first interaction or summon (Ash Blossom, Ghost Ogre, Maxx C, Infinite Impermanence), then rebuild the board into a Xyz
• Recovery: Exosister Xyz monsters and Xyz-Summon triggers when the opponent moves cards out of either GY let the deck rebuild from the GY and Extra Deck after a clean answer
• After siding: Not applicable: the list runs no Side Deck (0 cards) and no post-side data is recorded for Master Duel ranked play

Why it scores here

The deck reliably opens a functional Exosister engine: about 85% of opening 5-card hands contain at least one of the 12 Exosister Level 4 starters and search cards (Elis, Martha, Pax, Betrayal), an estimate from the hypergeometric model and labelled Inferred. Its interaction is layered across the hand (Ash Blossom, Ghost Ogre, Maxx C, Infinite Impermanence, roughly 76% to show a hand trap when going second), with backrow and GY-based answers adding breadth. Its closing power comes from Xyz monsters with strong ATK, notably Magnifica at 2800 with a second attack, and recursion through Exosister GY triggers. The score comes from consistency, interaction and closing power evaluated on the whole system, not from Exosister's popularity or from averaging card scores; no combos or win-rate data were supplied, so the floor and median are text-only inference and the score sits at Low confidence.

Dimension scores

How the score was computed

Strategy profile: Midrange. Structural ≈ 59, Going First ≈ 60, Going Second ≈ 60, Meta = provisional, Tournament Reliability ≈ 55. Modifiers: Engine conflicts and splash burden (-3); Banlist exposure (0). Final formula: 0.80*Structural + 0.20*TournamentReliability + ContextModifiers (Meta provisional): 0.80*59.34 + 0.20*55 - 3 = 55.5, rounded to 55

Probability & combo summary

• Opening a starter: P(≥1) ≈ 0.85 · 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

• Reliable Exosister starter access from the opening hand
• Layered hand-trap and backrow interaction covering both going-first and going-second
• High-ATK Xyz closing power with recursion through GY triggers
• Legal list at proper copy limits with no banlist exposure

Weaknesses

• No recorded combo data, so conversion and median output are unverified
• Only 51% exact-name Exosister purity; splash slots (Dominus Spark, Seventh Tachyon, Ecclesia, Albion) dilute the engine
• No Side Deck, so no post-side adaptation
• Several LP-cost cards (Pax, Vadis) and Xyz timing raise pilot difficulty

Critical choke points

• Exosister Level 4 starters (Elis, Martha) are needed early; the splash needs Fallen of Albaz (2 copies) to be live
• Off-archetype Extra Deck cards (Ecclesia, Albion) need Fallen of Albaz and cannot be reliably summoned without it

Recommended changes

Evidence & confidence

• Verified: Legal at 40 main, 15 extra, 0 side under Master Duel size rules; Banlist: Maxx C and Crossout Designator Limited at 1 copy; The Fallen & The Virtuous Semi-Limited at 2 copies; Copy histogram, Extra Deck breakdown and exact-name purity 50.9%; Card stats for Magnifica (2800/2800), Karmael (2600/1800) and Mikailis (2500/1800)
• Inferred: At least one Exosister starter in opening 5 is about 0.85 (hypergeometric); Hand-trap coverage about 76% going second; Interaction breadth and recovery from card text; Consistency and brick-risk judgments without combo or win-rate data; Going-first and going-second power estimates
• Provisional: Meta Power (null) and matchup fit (D13) lack a dated metagame sample; Side Deck adaptability (D12) is not applicable for this list
• Data gaps: no combos supplied — combo floor/median/ceiling is text-only inference no tournament link — archetype meta-share and per-pilot match record absent no win-rate telemetry (going-first/second, matchup, brick/starter rates) — those signals are Inferred or Unknown Meta Power is Provisional unless a dated metagame sample is supplied No Side Deck recorded; post-side plan cannot be evaluated
