Exosister Deck #774315 — Yu-Gi-Oh! Master Duel

Deck — Deck Power Evaluation

Final Contextual Deck Power: 59/100 (±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: Exosister Rank 4 Xyz monsters (Kaspitell, Karmael, Gibrine, Asophiel, Mikailis) built off Elis, Martha and Stella starters, with Exosisters Magnifica (2800 ATK, second attack) and Karmael as the closers.; Exosister Xyz Summons triggered when the opponent moves cards out of either Graveyard, using Sophia, Irene or Elis as material; Vadis and Returnia add recursion-based board plays.
• Turn 1 (going first): Open Elis or Martha (Martha only when no non-Xyz monsters are controlled), search or Special Summon a second Exosister, then Xyz Summon a Rank 4 Exosister to pressure and protect with Ash Blossom, Impermanence or Dominus Spark/Purge.
• Turn 2 (going second): Use hand traps (Ash Blossom, Droll & Lock Bird, Ghost Ogre, Ghost Belle, Ghost Mourner) to slow the opponent's first board, then rebuild with Exosister starters and Xyz through the opponent's Graveyard movement.
• Recovery: Betrayal and Pax recover Exosister monsters from the Deck; Irene and Sophia draw; Xyz materials are re-accessible through the Exosister Graveyard-trigger effects.
• After siding: Not supported by the evidence: the deck runs zero Side Deck cards, so there is no recorded post-side plan.

Why it scores here

The deck reliably opens an Exosister starter: Elis, Martha, Pax and Betrayal (12 copies) give an inferred ~85% chance of at least one in an opening 5, and the searchers and Xyz routes give it a usable T1 Xyz line. Conversion is strong on the system, not the card list: five Rank 4 Exosister Xyz and Magnifica give a high ceiling, and the Graveyard-movement trigger lets the deck Xyz Summon on the opponent's own plays. Interaction is the main strength: 10 hand traps plus Dominus Spark/Purge and Returnia cover the opponent's Quick Effects and first board, which carries the going-second case. The score is held back by Martha's restriction, the 27 off-archetype copies (about 51% exact-name purity), the absence of any recorded boards and an empty Side Deck. Popularity and usage statistics confirmed the list is real and accessible but did not add points, and card scores were not averaged.

Dimension scores

How the score was computed

Strategy profile: Combo. Structural ≈ 65, Going First ≈ 66, Going Second ≈ 64, Meta = provisional, Tournament Reliability ≈ 57. Modifiers: Engine conflict (Martha restriction) (-2); Off-archetype dilution (-2); No post-side plan (0). Final formula: 0.80*Structural + 0.20*TournamentReliability + ContextModifiers (Meta provisional; 0.80*65 + 0.20*57 = 63.4, modifiers -4, final 59)

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

• Compact Exosister starter set (Elis, Martha, Pax, Betrayal) with 3 copies each
• Ten hand traps and Dominus/Returnia removal cover the opponent's first board
• High-ATK Rank 4 Exosister Xyz pool with Magnifica and Karmael as closers
• Legal list with the one restricted card run at 1 of 2 allowed copies

Weaknesses

• Martha's Special Summon condition conflicts with non-Xyz monsters on the field
• 27 off-archetype copies dilute the Exosister engine
• Zero Side Deck cards: no post-side adaptation
• No recorded combos or matchup data to confirm the ceiling

Critical choke points

• The opening Elis/Martha/Pax/Betrayal starter (about 85% in an opening 5, Inferred)
• Graveyard movement by the opponent is needed to trigger the Xyz route in the mid-game

Recommended changes

Evidence & confidence

• Verified: Legal in master-duel: 40 Main, 15 Extra, 0 Side within size rules; Droll & Lock Bird runs 1 of 2 allowed copies (Semi-Limited); Card text and ATK/DEF for all 27 distinct cards read from the evidence; Usage stats: Ash Blossom, Elis, Martha, Pax, Betrayal at 100%/91-100% inclusion
• Observed: Usage statistics show core-card inclusion, meaning the list is real and accessible
• Inferred: Starter probability ~0.85 and hand-trap P(>=1 in 6) 0.85 from hypergeometric estimates; Combo primary strategy from Xyz route and Graveyard trigger text; Dimension scores D1-D11 from text and composition; Going-first and going-second powers
• Provisional: Meta Power (null, no dated metagame sample); D13 matchup and format fit (archetype share only; tournament data unavailable)
• 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: going-first, going-second, matchup and brick rates are Inferred Usage statistics in this deck flags disagree with the cards list for Extra Deck cards (Gibrine, Mikailis, Magnifica, Karmael, Asophiel, Masquerade show 0 in usage but copies in cards); cards list used, since its Extra total sums to 15 Meta Power provisional without a dated metagame sample
