Exosister Deck #773923 — Yu-Gi-Oh! Master Duel

Deck — Deck Power Evaluation

Final Contextual Deck Power: 54/100 (±7 · Confidence: Medium)

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

Legality

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

Identity & game plan

• Win condition: Exosister Xyz boss (Mikailis, Magnifica, Kaspitell, Karmael, Asophiel) built off Exosister Elis/Martha/Stella/Sophia/Irene summons, with Xyz triggered when the opponent moves cards out of a Graveyard; Extra-Deck breakers (Divine Arsenal AA-ZEUS, Super Starslayer TY-PHON, Star Seraph Sentry) once the board is established
• Turn 1 (going first): Open on Elis or Martha (or Stella/Sophia/Pax) to reach an Exosister board, use Pax or Betrayal to find the next Exosister, then Xyz when the opponent's GY is disturbed
• Turn 2 (going second): Use the hand traps (Ash Blossom, Ghost Belle, Droll and Lock Bird, Maxx C, Infinite Impermanence) to stop the opponent's first engine, then rebuild the Exosister board through the same summon chain
• Recovery: Pax and Betrayal re-search Exosister monsters; Irene and Sophia draw; Exosister Vadis and Returnia convert a board of Exosister monsters into a banish or Xyz line
• After siding: No side deck is registered (0 cards), so there is no evidenced post-side plan; Bo1 ladder play is assumed to be the default context

Why it scores here

The deck opens a live Exosister board most of the time: six Elis/Martha copies alone give about 58% (going first) and 65% (going second) odds of at least one in hand, and roughly 88% of going-second hands contain one of its 11 hand traps. Its ceiling is a Xyz line into Mikailis, Magnifica, Kaspitell or Karmael, but the Xyz trigger depends on the opponent moving cards out of a Graveyard, so the conversion is conditional and no recorded boards support it. Interaction density is high (Ash Blossom, Ghost Belle, Droll and Lock Bird, Maxx C, Infinite Impermanence), which earns the going-second and resilience scores, while the 0-card side deck, the Martha summon restriction and the LP-costly Pax and Returnia pull it down. Popularity (archetype usage stats) confirms the list is real and accessible but earned no points on its own, and the score is not an average of individual card scores.

Dimension scores

How the score was computed

Strategy profile: Combo. Structural ≈ 62.4, Going First ≈ 58, Going Second ≈ 67, Meta = provisional, Tournament Reliability ≈ 52. Modifiers: engine conflicts (-2); no side deck (-2); banlist exposure (-1); dependence on starter pair (-1). Final formula: 0.80*Structural + 0.20*TournamentReliability + ContextModifiers (Meta provisional, null): 0.80*62.4 + 0.20*52 - 6 = 54.3

Probability & combo summary

• Opening a starter: P(≥1) ≈ 0.58 · 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

• Hand-trap density (11 cards) gives strong going-second interaction
• Six Exosister summon starters across Elis, Martha, Stella, Sophia and Irene
• Xyz boss options (Magnifica, Mikailis, Kaspitell, Karmael) plus Extra-Deck breakers
• Legal, fully resolved list with no banlist violations

Weaknesses

• Xyz trigger depends on the opponent moving cards out of a Graveyard
• No side deck, so no best-of-3 adaptability
• Six single-copy tech cards and five Spirit monsters that conflict with the Exosister engine
• No recorded boards or telemetry to confirm the combo conversion rate

Critical choke points

• Elis or Martha in the opening hand (about 58% going first)
• The opponent moving cards out of a Graveyard, which triggers the Xyz engine
• Pax's 800 LP cost when life points are low

Recommended changes

Evidence & confidence

• Verified: Legal status with 40 main, 15 extra, 0 side; legal copy counts; 11 hand traps and 8 negation and 5 removal cards from card text; Usage stats: Exosister core cards at 100% inclusion, Maxx C 100%
• Inferred: Starter access and hand-trap odds from the hypergeometric estimates; Xyz conversion and interaction density from text, with no recorded boards
• Provisional: Meta and tournament fit (no dated sample or tournament link)
• Data gaps: No combos supplied: floor, median and ceiling are text-only inference No tournament link: archetype meta-share and per-pilot record absent No win-rate telemetry exists in YGOVN; all matchup and going-first/second claims are Inferred Meta Power is provisional without a dated metagame sample Data inconsistency: usage statistics marks Mikailis, Magnifica, Gibrine, Karmael, Asophiel, Albion, Ecclesia, ZEUS and TY-PHON as not in this deck, but the cards array lists them with copies 1-2; the core/missing-core analysis for Extra Deck cards is unreliable and was not used for scoring
