Exosister Deck #756577 — Yu-Gi-Oh! Master Duel

Deck — Deck Power Evaluation

Final Contextual Deck Power: 55/100 (±6 · Confidence: Medium)

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

Legality

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

Identity & game plan

• Win condition: Xyz Summon Exosister Magnifica, Mikailis, Karmael or Kaspitell off Exosister monsters, then convert the board with double attacks and banishes; Divine Arsenal and TY-PHON as off-archetype Xyz finishers when Exosister materials are present
• Turn 1 (going first): Special Summon Martha or Elis, use Sophia, Stella or Irene to establish a second Exosister body, then Xyz Summon from the Extra Deck
• Turn 2 (going second): Hold Ash Blossom, Droll and Lock Bird, Maxx C and Evenly Matched to answer the opponent first, then rebuild the Exosister board through Pax and Betrayal
• Recovery: Search with Betrayal and Pax, recycle Irene and Sophia from the GY, and use Vadis or Returnia to re-enter the Xyz route
• After siding: None: the deck runs 0 side cards, so there is no post-side plan

Why it scores here

The deck opens its engine reliably through three-copy starters (Martha, Elis, Pax, Betrayal) and a large Exosister core, which gives it redundant routes into Xyz Summons. Its interaction package is the strongest part of the system: nine hand traps and negation cards (Ash Blossom, Droll and Lock Bird, Maxx C, Evenly Matched, Forbidden Droplet) let it answer the opponent on either turn, and that density raises the going-second score. Its closing power comes from the Rank 8 and Rank 4 Xyz bosses (Magnifica, Mikailis, Karmael) and the level 12 finishers. The score is held back by the absence of recorded boards (no combo ceiling or median can be measured), Martha's Special Summon restriction, a 0-card side deck, and no tournament or win-rate data. Archetype popularity earned no points by itself, and the score was built from the system's dimensions, not by averaging individual card scores.

Dimension scores

How the score was computed

Strategy profile: Combo 100% (Midrange used only as a qualitative secondary read; no weight blending). Structural ≈ 62, Going First ≈ 60, Going Second ≈ 66, Meta = provisional, Tournament Reliability ≈ 55. Modifiers: Banlist exposure (-1); Restrictive engine piece (-2); No post-side plan (-2). Final formula: 0.80*Structural + 0.20*TournamentReliability (Meta provisional) + ContextModifiers = 0.80*61.8 + 0.20*55 - 5 = 55.4

Probability & combo summary

• Opening a starter: P(≥1) ≈ 1 · 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 starters and a 27-copy Exosister core give redundant engine access
• Layered interaction: nine hand traps and negation/removal cards answer on either turn
• Strong Extra Deck closers (Magnifica, Karmael, Mikailis) with double-attack and banish effects
• Legal construction: all restricted cards within legal copy counts

Weaknesses

• No recorded boards: the combo ceiling and median cannot be measured
• Martha's Special Summon restriction limits flexibility
• Zero side deck: no post-side plan
• Off-archetype Xyz (Zeus, TY-PHON, Eclipse Twins) and generic staples dilute the engine

Critical choke points

• Martha/Elis Special Summon line: if the starter is blocked or lost, the Xyz route slows
• Single-copy Vadis, Returnia and Sophia cannot be relied on in a given hand
• Dependence on LP for Pax and Vadis costs

Recommended changes

Evidence & confidence

• Verified: Legal size 40/15/0 with all restricted cards within legal copies; Card text and stats for all 40 main and 15 extra cards; Archetype purity 50.9 percent exact-name
• Observed: Usage statistics show the Exosister core is standard (100 percent inclusion for the core Xyz and starters)
• Inferred: Starter access and brick estimates from hypergeometric numbers; Combo ceiling and interaction value from card text; Going-second hand-trap value (0.808)
• Provisional: Meta and matchup fit (no dated sample); Side-deck adaptability (no side cards); Tournament reliability
• 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 absent No win-rate telemetry for this deck (going-first/second, matchup, brick rates) Usage statistics mark several Extra Deck cards (Mikailis, Karmael, Magnifica, Gibrine, Kaspitell, Zeus, TY-PHON) as in_this_deck = false, while the cards list shows them at copies 1-3; the usage join appears to ignore the Extra Deck, so the core-presence figure (52 percent) is understated Meta Power is Provisional unless a dated metagame sample is supplied
