Exosister Deck #718756 — Yu-Gi-Oh! Master Duel

Deck — Deck Power Evaluation

Final Contextual Deck Power: 35/100 (±10 · Confidence: Low)

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

Legality

Main 40 / Extra 15 / Side 0 — status: Illegal. 2 violation(s).

Identity & game plan

• Win condition: Xyz Summon Exosister Xyz monsters (Mikailis, Magnifica, Karmael, Asophiel) off the opponent's graveyard-movement triggers and attack for lethal; Exosister Gibrine and Kaspitell as board-control Xyz that also negate or banish
• Turn 1 (going first): Open Elis, Martha, Betrayal, Pax or Irene to Special Summon Exosister monsters, then use the opponent's graveyard movement (or your own) to Xyz Summon a 2800-ATK Magnifica or 2600-ATK Karmael
• Turn 2 (going second): Use Ash Blossom, Infinite Impermanence and Maxx C to answer the opponent's first summon, then rebuild the Exosister board for an Xyz Summon the following turn
• Recovery: Exosister searchers (Betrayal, Pax, Irene, Sophia) rebuild the monster zone from the Deck; Returnia and Vadis add interaction
• After siding: No side deck (0 cards). Post-side plan is not defined by the list; treat as unavailable.

Why it scores here

The deck is scored as a system: the 33 exact Exosister copies and the Exosister searchers (Betrayal, Pax, Irene, Sophia) make the core engine reliably reachable (P(at least one of the 25-card archetype core in a 5-card opening hand) is about 0.995, Inferred). Its Xyz Extra Deck (Magnifica, Karmael, Mikailis, Asophiel) gives a real closing ceiling with 2600 to 2800 ATK bodies, but no recorded boards exist, so the ceiling and median are text-only inference. Interaction (Ash Blossom, Infinite Impermanence, Maxx C, Crossout Designator, Exosister Returnia) is dense and multi-layered, and it helps on the going-second side. The deck does not earn points from Exosister popularity (usage and guides confirm it is real, not that it is strong), and card scores were not averaged. It is capped because two Forbidden cards (Called by the Grave, Dimension Shifter) are run in the Main Deck; the Dimensional Fissure floodgate also conflicts with Exosister's own graveyard-based triggers.

Dimension scores

How the score was computed

Strategy profile: Combo. Structural ≈ 60, Going First ≈ 58, Going Second ≈ 55, Meta = provisional, Tournament Reliability ≈ 50. Modifiers: banlist exposure (-6); engine conflict (-3). Final formula: Illegal cap: Structural 60 (Combo profile) with no-meta formula 0.80*60 + 0.20*50 = 58, modifiers -9 gives 49; capped to 35 because the list is Illegal (Forbidden cards in Main). Theoretical/structural-only.

Probability & combo summary

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

Strengths

• Core Exosister engine is highly accessible (about 0.995 of openings contain a core card, Inferred)
• Xyz Extra Deck offers 2600 to 2800 ATK closers with a compact 15-card Extra Deck
• Layered interaction from hand traps and Limited spells

Weaknesses

• Two Forbidden cards in the Main Deck make the list illegal
• No side deck, so no post-side adaptability
• Dimensional Fissure works against the deck's own graveyard triggers
• 22 off-archetype copies raise brick and dead-draw risk

Critical choke points

• Exosister Xyz summon depends on the opponent or the player moving cards out of the graveyard
• Pax and Returnia LP cost (800 each) in a long game

Recommended changes

Evidence & confidence

• Verified: Main Deck is 40 cards, Extra Deck is 15 cards, Side Deck is 0 cards (within Master Duel limits); Called by the Grave and Dimension Shifter are Forbidden and run with 1 copy each; Maxx C, Crossout Designator and Pot of Extravagance are Limited and run at 1 copy each (legal)
• Observed: Exosister is a real deck: 2 guides and 27 usage-stat rows exist for the archetype
• Inferred: Core engine accessibility about 0.995 (hypergeometric, 25 core copies); Structural 60 from the Combo weight profile
• Provisional: Meta power (no dated metagame sample); Matchup fit (no tournament link)
• 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 exists in YGOVN — matchup and going-first/second signals are Inferred or Unknown Meta Power is Provisional unless a dated metagame sample is supplied No Side Deck supplied, so post-side plan cannot be evaluated
