Exosister Deck #774319 — Yu-Gi-Oh! Master Duel

Deck — Deck Power Evaluation

Final Contextual Deck Power: 64/100 (±7 · Confidence: Medium)

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

Legality

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

Identity & game plan

• Win condition: Xyz Summon high-ATK Exosister Xyz monsters (Magnifica 2800, Karmael 2600, Mikailis 2500) off Exosister monsters, enabled by opponent moving cards out of either GY.; Board-building through Exosister Special Summons (Elis, Martha, Stella, Sophia) with Xyz Summon triggers on the field.
• Turn 1 (going first): Starter from hand (Elis, Martha, Pax, Betrayal) into Exosister board, then Xyz Summon off GY-move triggers; hold hand traps where possible.
• Turn 2 (going second): Hand traps (Ash Blossom, Ghost Ogre, Droll & Lock Bird, Infinite Impermanence) to interrupt the opponent's board, then rebuild Exosister Xyz from the field.
• Recovery: Searchers (Betrayal, Irene, Pax) and Sophia/Stella/Elis recursion restock the Exosister board after a disruption.
• After siding: Not applicable: Master Duel is single-game with an empty side deck (side_count 0).

Why it scores here

The deck reliably opens an Exosister board: the searcher text group (9 copies) has P(at least one in a 5-card opening hand) ≈ 0.74, and the core archetype group is present in essentially every hand (≈ 0.9996), so the engine is accessible on T1–T2 (Inferred). It converts that board into Xyz pressure through a wide set of Extra Deck targets: Magnifica, Karmael, Mikailis, and Asophiel all turn GY-movement by the opponent into a Xyz Summon route, giving several independent conversion lines. Interaction is broad for a Master Duel list: nine hand-trap-tagged cards, Dominus Spark, Infinite Impermanence, Ghost Ogre, Returnia and Magnifica banish effects. The deck is held back by Martha's restriction on Extra Deck summons (only Exosister monsters after activation), LP-paying effects (Pax, Vadis, Returnia), and no combo or tournament records, so floor and median output are estimates; the score comes from consistency, interaction and Xyz conversion on the system, not from Exosister's popularity or from averaging card scores.

Dimension scores

How the score was computed

Strategy profile: Midrange primary, Combo secondary (disclosed; Midrange weights used for scoring). Structural ≈ 65, Going First ≈ 66, Going Second ≈ 68, Meta = provisional, Tournament Reliability ≈ 60. Modifiers: Xyz route redundancy (2); Engine conflicts (-2). Final formula: 0.80*Structural + 0.20*TournamentReliability (Meta provisional); 0.80*65.45 + 0.20*60 = 64.36, modifiers net 0

Probability & combo summary

• Opening a starter: P(≥1) ≈ 0.74 · 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

• Engine accessibility: searcher and core Exosister density give a high chance of a live T1–T2 board (Inferred).
• Extra Deck coverage: multiple Xyz routes triggered by the same GY-move condition.
• Interaction breadth: hand traps, banish effects and negation text cover several opposing plans.

Weaknesses

• Martha's summon restriction and LP-paying effects slow the line and tax resources.
• Purity is only 54.5% exact-name, with 25 off-archetype copies and generic staples.
• Floodgate tech (Dimensional Fissure) can conflict with the deck's own GY-based recursion (Inferred).

Critical choke points

• Opening-hand starter access: each 3-copy starter is ≈ 0.34 in a 5-card hand, so the searcher group carries the line.
• The GY-move trigger for Xyz Summons depends on the opponent moving cards out of a GY.

Recommended changes

Evidence & confidence

• Verified: Main 40 / Extra 15 / Side 0 legal for master-duel; Droll & Lock Bird 1 of 2 copies (Semi-Limited).; Card text and stats for all 40 distinct cards; archetype core usage (Exosister core 100% inclusion for Elis, Martha, Pax, Ash, Betrayal).
• Observed: Usage stats: 28 archetype stat rows; archetype core present in deck.
• Inferred: Hypergeometric starter, brick and hand-trap estimates; semantic read of negation, removal and Xyz-route text; Midrange-profile scoring.
• Provisional: Meta Power (no dated meta sample); matchup fit and tournament reliability (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 (going-first/second, matchup, game-level, brick/starter/OTK rates) — those signals are Inferred or Unknown Meta Power is Provisional unless a dated metagame sample is supplied no side deck exists in Master Duel single-game play, so D12 has no post-side evidence
