Exosister Deck #773256 — Yu-Gi-Oh! OCG

Deck — Deck Power Evaluation

Final Contextual Deck Power: 35/100 (±8 · Confidence: Low)

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

Legality

Main 55 / Extra 15 / Side 0 — status under the rules at evaluation time: Illegal. 1 violation(s).

Identity & game plan

• Win condition: Xyz pressure from Exosister Xyz monsters (Magnifica, Karmael, Mikailis, Gibrine) built off Exosister Elis, Martha, Stella and Sophia extenders; Divine Arsenal AA-ZEUS and Super Starslayer TY-PHON as high-ATK Extra Deck closers (Inferred, no board data)
• Turn 1 (going first): Open Exosister starter (Elis or Martha) with Betrayal or Pax to find a second Exosister, then Xyz Summon through Extra Deck Exosisters; hold Ash and Impermanence for the opponent's first activation
• Turn 2 (going second): Use the 6-card hand's hand traps (Ash, Impermanence, Evenly Matched, Droll, D.D. Crow) to break the opponent's first board, then extend with Exosister monsters
• Recovery: Exosister monsters and Betrayal recur and re-search the engine; Pax and Arment re-start the Xyz line from the Graveyard (Inferred from card text)
• After siding: Not assessable: the deck has no Side Deck, so there is no post-side plan

Why it scores here

This is an illegal list: Ash Blossom & Joyous Spring is run three times against an OCG limit of two, so the score is structural-only and capped at 35. The Exosister core is reliable on paper, with a 96.6% chance of at least one core card in the opening five, and the Extra Deck gives multiple Xyz closers. The deck's interaction density is high, with about twelve hand-trap and disruption cards plus floodgates, so it should hold up well on the second turn. Weak points are the lack of any Side Deck, around 25 tech-tagged slots that can brick, and no recorded boards or tournament results to confirm the median output. The score comes from consistency, interaction and closing power on the system, not from Exosister's popularity or from averaging the card scores.

Dimension scores

How the score was computed

Strategy profile: Midrange. Structural ≈ 58, Going First ≈ 56, Going Second ≈ 62, Meta = provisional, Tournament Reliability ≈ 50. Modifiers: banlist_exposure (-8); no_side_deck (-4); illegal_cap (0). Final formula: Illegal list: structural-only. Unconstrained 0.80*58 + 0.20*50 = 56, with modifiers -12 giving 44, then capped at 35 for Illegal status. Meta Power provisional.

Probability & combo summary

• Opening a starter: P(≥1) ≈ 0.97 · key two-card combo ≈ — · full-brick estimate ≈ 0.03 (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 almost always accessible in the opening hand (Inferred)
• Broad, layered interaction: hand traps, floodgates and backrow removal (Verified text, Inferred quality)
• Several Xyz closers in the Extra Deck with high ATK (Verified)

Weaknesses

• Illegal list: Ash Blossom & Joyous Spring over the Semi-Limited limit (Verified)
• No Side Deck (Verified)
• About 25 tech-tagged slots and 47% exact-name purity raise brick and dead-card risk (Verified composition, Inferred impact)
• No recorded boards, tournament data or matchup data to confirm median output (Verified gap)

Critical choke points

• Exosister starter density depends on Elis and Martha, which the deck runs 3 each (Inferred)
• Pax and Returnia cost 800 LP each (Verified)

Recommended changes

Evidence & confidence

• Verified: Main 55, Extra 15, Side 0 (within OCG size rules); Ash Blossom & Joyous Spring 3 copies vs OCG Semi-Limited limit 2 (Illegal); Droll & Lock Bird and S:P Little Knight are Limited, 1 copy each (legal); Exosister core copies 26; hand-trap group 12 and searcher group 10; Extra Deck: 14 Xyz, 1 Link
• Observed: Usage stats: Elis 93%, Martha 91%, Pax 86%, Betrayal 84% inclusion in the archetype sample
• Inferred: P(at least one core in opening 5) = 0.966 gives high engine accessibility; Hand-trap density gives P(hand trap in going-second 6) = 0.79; Brick and dead-card risk from about 25 tech-tagged slots; Xyz closers can end the game from one stable board
• Provisional: Meta and matchup fit (no tournament link or dated sample); Median combo output (no recorded boards)
• 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 are absent no win-rate telemetry; going-first, going-second, matchup and brick rates are Inferred or Unknown Meta Power is Provisional without a dated metagame sample no guides attached (guides_evidence total 0)
