Exosister Deck #773211 — Yu-Gi-Oh! OCG

Deck — Deck Power Evaluation

Final Contextual Deck Power: 55/100 (±6 · Confidence: Medium)

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

Legality

Main 55 / Extra 15 / Side 0 — status: Legal.

Identity & game plan

• Win condition: Hand-summon a Level 4 Exosister (Elis, Martha or Stella), chain into a second Level 4 Exosister, then Xyz Summon a Rank 4 or Rank 8 Exosister Xyz (Magnifica, Mikailis, Karmael, Asophiel, Kaspitell, Gibrine) to take over the board.; Draw and search engine (Sophia, Irene, Betrayal, Pax) grinding card advantage and LP, with Dark Hole and Cosmic Cyclone as reset interaction.
• Turn 1 (going first): Opening hand with a Level 4 Exosister plus one searcher or draw card; Normal Summon or hand-summon into a second Level 4 Exosister, Xyz Summon a Rank 4 Exosister Xyz, and hold Cosmic Cyclone, Forbidden Chalice or Breakthrough Skill for the opponent's response.
• Turn 2 (going second): Six-card hand to find a Level 4 Exosister, then use Dark Hole or Cosmic Cyclone to clear or strip the opponent's first board before rebuilding with Exosister hand-summons and an Xyz.
• Recovery: Exosister monsters revive from hand and from the GY via Xyz material effects; Pax, Betrayal and Small World refill the hand, and Elis/Stella LP gain covers the LP cost of Pax and Returnia.
• After siding: No side deck is registered (0 of 15 slots used), so there is no evidenced post-side plan.

Why it scores here

This Exosister list reliably opens a functional engine: about 9 Level 4 hand-summon Exosisters (Elis, Martha, Stella) plus 4 more draw and searcher Exosisters, with a 5-card going-first opener containing at least one hand-summon starter about 61% of the time (Inferred, hypergeometric). Conversion rests on Exosister Xyz plays into Magnifica, Mikailis and Karmael, but no recorded boards exist, so the ceiling is a semantic read, not an observed number. Interaction is the strongest pillar: Dark Hole, Cosmic Cyclone, Ultimate Slayer, Breakthrough Skill and Forbidden Chalice give about 17 removal and 7 negation text roles, and LP-gain plus card advantage (Sophia, Irene, Betrayal) carries grind. The deck has no hand traps and no side deck, which keeps going-second and post-side scores modest. Popularity (Exosister core inclusion rates) confirms this is a real, accessible list, not a strong one; the score comes from consistency, interaction and resource economy on the system, not from averaging card scores.

Dimension scores

How the score was computed

Strategy profile: 100% Combo profile (Midrange noted as secondary strategy, not blended). Structural ≈ 59.8, Going First ≈ 67, Going Second ≈ 62, Meta = provisional, Tournament Reliability ≈ 54. Modifiers: No side deck (-2); Dead Extra Deck slots (-2). Final formula: 0.80*Structural + 0.20*TournamentReliability + ContextModifiers (Meta provisional): 0.80*59.8 + 0.20*54 = 58.6, then -4 modifiers = 54.6, rounded to 55

Probability & combo summary

• Opening a starter: P(≥1) ≈ 0.61 · key two-card combo ≈ 0.18 · full-brick estimate ≈ 0.07 (all Inferred)
• Combo output: best PowerIndex —, median —, board-per-starter —
• Turn order: 0 going-first lines vs 0 going-second lines

Strengths

• Three Level 4 hand-summon starters at 3 copies each give consistent access to the Xyz engine
• Heavy interaction suite (Dark Hole, Cosmic Cyclone, Ultimate Slayer, Breakthrough Skill, Chalice, Barrier) with 17 removal and 7 negation text roles
• Strong LP and card-advantage engine (Elis/Stella LP gain, Sophia/Irene draw, Betrayal 2-for-1)
• Legal list: all cards Unlimited, no restricted cards, size 55/15/0 inside OCG rules

Weaknesses

• No hand traps and no side deck, so going-second and best-of-3 plans are thin
• Low archetype purity (47.1%) with 29 spells and several off-archetype tech cards
• Two Extra Deck slots look dead (Wind Pegasus, Fossil Warrior Skull Knight)
• No recorded boards, so floor, median and ceiling are inferred and low-evidence

Critical choke points

• Starting a Xyz needs two Level 4 Exosisters on field; a hand with only one hand-summon starter (≈ 0.43 going first) relies on draw or search to find the second
• Pax and Returnia cost 800 LP each, so repeated use depends on Elis/Stella LP gain

Recommended changes

Evidence & confidence

• Verified: Main 55, Extra 15, Side 0; legal under OCG size rules; All 70 copies are Unlimited; restricted_cards empty; Card text for interaction, searcher and LP-cost cards; usage_statistics show Exosister core inclusion ≥ 50% for the listed core cards
• Observed: Archetype core inclusion rates from usage_statistics
• Inferred: P(≥1 Level 4 hand-summon starter) ≈ 0.61 going first, ≈ 0.68 going second; P(≥2 starters going first) ≈ 0.18; Brick proxy ≈ 0.07; Dead status of Wind Pegasus and Fossil Warrior Skull Knight; Engine ceiling and Xyz conversion from card text
• Provisional: Meta Power (no dated sample); D13 matchup and format fit; Going-second board-breaking in real games
• 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 splits are Inferred usage_statistics in_this_deck flags are false for Extra Deck cards that the deck does run (Karmael, Mikailis, Asophiel, Magnifica, Kaspitell, Gibrine); core_present_pct 50 is understated and missing_core is unreliable for the Extra Deck No side deck, so no post-side evidence Meta Power is Provisional
