Exosister Deck #772301 — Yu-Gi-Oh! OCG

Deck — Deck Power Evaluation

Final Contextual Deck Power: 66/100 (±6 · Confidence: Medium)

• Primary strategy: Combo
• Secondary strategies: Midrange, Stun
• Format: ocg

Legality

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

Identity & game plan

• Win condition: Xyz Summon high-ATK Exosister boss monsters (Mikailis, Magnifica, Karmael, Kaspitell) off Exosister starters and Xyz-material loops, then close with direct attacks and the 2800 to 3000 ATK boards.; Divine Arsenal AA-ZEUS and Super Starslayer TY-PHON as one-card Extra Deck closers when the Exosister line is intact.
• Turn 1 (going first): Turn 1: Elis, Martha, Betrayal or Pax from hand or Deck to reach 2 Exosister monsters, then Xyz Summon an Exosister boss from the Extra Deck.
• Turn 2 (going second): Hold Infinite Impermanence, Ash Blossom, Maxx C and Droll & Lock Bird to answer the opponent's first summons or search, then run the Exosister engine from the remaining hand.
• Recovery: Use Exosister GY and Xyz-material effects (Elis, Stella, Sophia, Irene), Betrayal recursion and Pax to rebuild after a single disruption.
• After siding: Not defined: the export lists no Side Deck, so there is no post-side plan.

Why it scores here

The deck reliably opens its engine: 27 archetype-core copies give a near-certain core in the opening hand, and P(at least one of Elis, Martha, Pax or Betrayal in hand of 5) is about 0.85 (Inferred). Conversion is strong on paper, with several 2300 to 3000 ATK Xyz bosses and two 3000-class closers, but no recorded boards exist, so the ceiling and median are text-only and held to a modest band. Interaction is layered through 7 hand traps, 6 negation-text cards and 5 removal-text cards, which carries the deck through disruption. The score comes from consistency, median output and interaction judged on the system; the popularity signal (archetype core in usage stats) and the individual card powers were not averaged in. Missing sideboard, absent combos and a usage-stats mismatch cap confidence and pull the score down.

Dimension scores

How the score was computed

Strategy profile: Combo. Structural ≈ 70, Going First ≈ 74, Going Second ≈ 68, Meta = provisional, Tournament Reliability ≈ 60. Modifiers: No side deck (-2); Limited and Semi-Limited exposure (-1); Single-choke Seventh Tachyon (-1); Engine compactness (2). Final formula: 0.80*Structural + 0.20*TournamentReliability + ContextModifiers (Meta provisional, no dated sample)

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

• Core Exosister engine is near-certain in the opening hand (27 core copies).
• Seven hand traps plus negation and removal text give layered interaction.
• Extra Deck has high-ATK Xyz closers with Extra-slot flexibility.
• Seven distinct starter and searcher routes give recovery after one disruption.

Weaknesses

• No sideboard, so no post-side plan.
• No combo boards recorded, so median and ceiling are unmeasured.
• Ichiki Sayori-Hime is a low-impact 3-copy card that can brick a hand.
• LP-costed lines (800 to 1000 LP) add real cost in long rounds.

Critical choke points

• Seventh Tachyon depends on Number 104: Masquerade being in the Extra Deck.
• Exosister boss summons depend on the starter monsters surviving the opponent's first interaction.

Recommended changes

Evidence & confidence

• Verified: Legal in OCG: 40 Main, 15 Extra, 0 Side; no violations.; Limited and Semi-Limited copies are within legal limits.; Usage stats: archetype core inclusion rates present (21 core cards listed).
• Observed: Exact-name Exosister purity is 56.4%.
• Inferred: Starter hypergeometric estimates and consistency reads.; Interaction density from text flags.; Going-second and resilience reads from card text.
• Provisional: Meta and matchup fit (no dated sample or tournament link).
• Data gaps: No combos supplied: combo floor, median and ceiling are text-only inference. No tournament link: archetype meta-share and per-pilot record absent. No win-rate telemetry: going-first, going-second and matchup signals are Inferred or Unknown. Meta Power is Provisional unless a dated metagame sample is supplied. Usage stats mark Exosister Karmael, Magnifica, Kaspitell, Gibrine, Asophiel, Mikailis, Divine Arsenal AA-ZEUS and TY-PHON as not in this deck (in_this_deck false), but the cards array lists all of them in the Extra Deck with copies 1 to 3; the usage-stat match is inconsistent and was not used. No Side Deck cards in the export.
