Exosister Deck #771621 — Yu-Gi-Oh! OCG

Deck — Deck Power Evaluation

Final Contextual Deck Power: 30/100 (±10 · Confidence: Low)

• Primary strategy: Combo
• Secondary strategies: Midrange, Xyz/Extra-Deck engine
• Format: ocg

Legality

Main 55 / Extra 15 / Side 0 — status under the rules at evaluation time: Illegal. 2 violation(s).

Identity & game plan

• Win condition: Exosister Xyz Monsters (Exosisters Magnifica 2800 ATK, Exosister Karmael 2600 ATK, Exosister Mikailis 2500 ATK) built from Exosister Level 4 monsters, with Xyz Summon routes fed by Exosister Elis, Martha, Sophia, Stella and Irene.; Direct pressure from Xyz boards with second-attack and banish effects (Magnifica) plus Exosister Betrayal and Pax to reload the Exosister board; the deck does not show a second independent finisher in the evidence.
• Turn 1 (going first): Open with Exosister Elis or Martha (Special Summon from hand with an Exosister on the field), search with Exosister Betrayal or Seventh Ascension, and build toward an Exosister Xyz Summon; the exact turn-1 sequence is not supported by recorded boards (no combos supplied).
• Turn 2 (going second): Use Dark Hole, Mask/Blizzard-type interaction and Exosister Irene/Sophia draws to reach an Xyz board through an opponent's turn; the evidence does not show a verified going-second line.
• Recovery: Exosister Irene and Sophia draw cards and gain LP; Exosister Betrayal and Pax search back Exosister monsters; Exosister Returnia (1 copy) is the only recovery trap in the deck.
• After siding: No Side Deck is registered (Side Deck size 0), so there is no post-side plan in this list; a best-of-3 build would need a side to be evaluated.

Why it scores here

This list is Illegal in OCG because it runs 3 copies of Dimension Shifter, a Forbidden card, so it is scored as a structural-only read and capped low. The Exosister core is reasonably accessible (16 core copies give roughly 83% chance of at least one in a 5-card opening hand, per the hypergeometric proxy), and the Extra Deck of Exosister Xyz Monsters gives real closing power. Conversion and floor output are unmeasured because the deck has no recorded boards, so the combo ceiling and median are text-based inferences rather than observed results. Brick and off-archetype density (only 40% exact-name purity, with 22 generic and 20 other sub-archetype copies) pull consistency down, and the empty Side Deck removes any post-side plan. Popularity of the archetype (core cards in the 75–94% usage range) confirms the list is real and accessible but did not earn points on its own, and the score was built from the system dimensions rather than from averaging individual card scores.

Dimension scores

How the score was computed

Strategy profile: Combo. Structural ≈ 49, Going First ≈ 45, Going Second ≈ 40, Meta = provisional, Tournament Reliability ≈ 35. Modifiers: Banlist exposure (illegal) (-10); No side deck (-2). Final formula: 0.80*Structural + 0.20*TournamentReliability (Meta provisional) + ContextModifiers (-12) = 34.5, then capped at 30 because the deck is Illegal (theoretical/structural-only)

Probability & combo summary

• Opening a starter: P(≥1) ≈ 0.25 · 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

• Large Exosister core (16 copies) gives high probability of at least one core monster in opening 5 cards (~83%).
• Extra Deck of 15 Xyz monsters has strong closing bodies (Magnifica 2800 ATK, Karmael 2600 ATK, Mikailis 2500 ATK).
• Multiple removal-text and negation-text cards (16 removal, 9 negation) give interaction breadth.

Weaknesses

• Illegal in OCG: 3 copies of Dimension Shifter (Forbidden).
• Only 40% exact-name Exosister purity; 22 generic and 20 other-sub-archetype copies dilute the engine.
• No Side Deck (0 cards), so no post-side plan.
• No recorded combos or win-rate data; combo ceiling and median are text-based only.

Critical choke points

• Exosister Elis/Martha starter access: the core engine depends on a monster from hand with an Exosister on the field.
• Forbidden Dimension Shifter in hand is a dead card and forces a legal-copy correction before any real evaluation.
• Single Xyz-Summon route into the Exosister Extra Deck without a verified independent second line.

Recommended changes

Evidence & confidence

• Verified: Legality: Dimension Shifter 3 copies Forbidden in OCG (illegal).; Main 55, Extra 15, Side 0; OCG size rules 40-60, 0-15, 0-15 (size legal).; Exosister Xyz stats (Magnifica 2800 ATK, Karmael 2600 ATK, Mikailis 2500 ATK).; Usage stats: Exosister Elis 93.75%, Martha 92.19% inclusion.
• Inferred: Hypergeometric starter access ~0.83 for the 16-copy Exosister core.; Brick and off-archetype dilution from the 40% exact-name purity.; Closing power from Xyz boards and banish/negate text.; Going-first and going-second plans from card text only.
• Provisional: Meta Power and matchup fit: no dated meta sample or tournament link.; Median/floor output: no recorded boards.
• 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 deck has no Side Deck, so no post-side evidence deck is Illegal (Dimension Shifter x3), so the score is capped and structural-only
