Exosister Deck #765412 — Yu-Gi-Oh! Master Duel

Deck — Deck Power Evaluation

Final Contextual Deck Power: 60/100 (±7 · Confidence: Medium)

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

Legality

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

Identity & game plan

• Win condition: Xyz Summon Exosister Xyz monsters (Magnifica 2800 ATK, Karmael 2600 ATK, Mikailis 2500 ATK, Kaspitell 2300 ATK) by using Exosister monsters the opponent's GY moves trigger, then attack with the second-attack and piercing-style bodies.; Flex Xyz bodies from the Extra Deck (ZEUS, TY-PHON, Masquerade) when the Exosister core is not live.
• Turn 1 (going first): Summon Exosister Martha from hand only if you control no monsters (or only Xyz), Special Summon Exosister Elis from Deck, then build a second Exosister and wait for the opponent to move cards out of a GY to start Xyz Summons.
• Turn 2 (going second): Use Ash Blossom & Joyous Spring, Ghost Ogre & Snow Rabbit, Maxx C and Dominus Spark / Purge to break the opponent's first summon or search, then rebuild Exosister board presence through Elis, Martha and Betrayal.
• Recovery: Exosister Pax (800 LP) and Exosister Betrayal refill the hand with Exosister cards; GY-triggered Xyz Summons turn a single surviving Exosister monster into a board.
• After siding: None: the list runs 0 side cards, so there is no post-side plan. Master Duel side-deck slots (0-15) are unused.

Why it scores here

The deck reliably opens a live starter in most hands: the 15 Exosister starters (Elis, Martha, Betrayal, Pax at 3 copies each, plus Stella, Sophia, Irene) give roughly 92% going-first and 95% going-second odds of at least one starter in the opening hand (Inferred hypergeometric, ignoring Martha's no-monster condition). It converts into pressure through Xyz Summons that the opponent's own GY movement triggers, and the Extra Deck ceiling (Magnifica, Mikailis, Karmael, ZEUS, TY-PHON) is high. Its survival rests on six hand traps and six Dominus-style or Dimensional-Fissure interaction cards, though several of these are conditional. The score is built from consistency, interaction and conversion on the whole system; popularity of the archetype and the 50.9% exact-name purity did not earn points, and no card scores were averaged.

Dimension scores

How the score was computed

Strategy profile: Combo. Structural ≈ 66, Going First ≈ 60, Going Second ≈ 64, Meta = provisional, Tournament Reliability ≈ 58. Modifiers: banlist exposure (-1); engine conflict (-2); no post-side plan (-1). Final formula: 0.80*Structural + 0.20*TournamentReliability + ContextModifiers (Meta provisional, no dated meta sample)

Probability & combo summary

• Opening a starter: P(≥1) ≈ 0.92 · 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

• At least one starter in most hands (Inferred, ~92% first / ~95% second)
• Xyz ceiling from 2500-2900 ATK bodies plus double attack from Magnifica
• Six hand traps plus Dominus cards give layered interaction
• Compact main deck with 10 three-of slots

Weaknesses

• Martha's no-monster condition conflicts with monster-heavy lines
• Engine depends on the opponent moving cards out of a GY
• No side deck, so no post-side adaptation
• LP cost on Pax and Elis, with no recorded boards to confirm the conversion

Critical choke points

• Exosister Martha/Elis summon conditions on going first
• Opponent not moving cards out of a GY, which leaves the Xyz trigger unused
• Hand-trap availability on going second

Recommended changes

Evidence & confidence

• Verified: Legal status: 40 Main, 15 Extra, 0 Side, all copy limits respected; Maxx C is Limited at 1 legal copy and is run at 1; Card texts for the starters, hand traps and Xyz monsters as listed in the evidence; Core Exosister copy counts from the composition
• Inferred: Starter access about 92% going-first and 95% going-second (hypergeometric, ignoring state conditions); Hand-trap access about 58% going-first and 65% going-second; Engine conflicts from card text (Martha vs monsters, Fissure vs GY); Interaction and recursion quality from text
• Provisional: Meta Power and matchup fit: no dated metagame sample or tournament link; Side-deck adaptability: no post-side data and 0 side cards
• 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 and going-second split is Inferred Meta Power is Provisional without a dated metagame sample usage statistics marks all Extra-Deck cards as not in deck (for example Mikailis, Magnifica, Karmael, Masquerade, ZEUS, TY-PHON, Little Knight) even though cards[] lists them in zone extra with copies. The core-card presence of 60 likely undercounts; treated as an evidence-pipeline inconsistency, not a deck fact. Side deck is empty (0 cards), so post-side adaptability cannot be assessed
