Exosister Deck #772834 — Yu-Gi-Oh! OCG

Deck — Deck Power Evaluation

Final Contextual Deck Power: 40/100 (±10 · Confidence: Low)

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

Legality

Main 60 / Extra 15 / Side 0 — status under the rules at evaluation time: Illegal. 3 violation(s).

Identity & game plan

• Win condition: Xyz Summon Exosister Xyz monsters (Magnifica, Karmael, Kaspitell, Mikailis, Gibrine, Asophiel) from Exosister monster material, then convert the 2600-2800 ATK boards with double attack and banish effects; Disruption-backed Xyz beatdown: Ghost Ogre, Ghost Belle, Ash Blossom, Droll & Lock Bird and Evenly Matched protect the board while Exosister Xyz monsters attack
• Turn 1 (going first): Normal Summon Exosister Stella or Martha, or activate Exosister Betrayal / Exosister Pax to search Exosister monsters, then build a 2-monster Xyz with an Exosister Xyz Monster, holding Ash or Ghost Ogre for the opponent's response
• Turn 2 (going second): Keep a six-card hand with a hand trap (Ash, Ghost Ogre, Ghost Belle, Droll, Infinite Impermanence or D.D. Crow) and answer the opponent's first board, then Xyz Summon through the open field
• Recovery: Pax, Betrayal and Sophia reload Exosister monsters from the Deck, and Stella or Elis recovers board presence from the GY after an interruption
• After siding: Not evaluable: the deck runs 0 side cards, so there is no post-side plan (best-of-three adaptation is absent)

Why it scores here

The deck reliably opens its engine: the 26 archetype-core copies give about a 95% chance of at least one core card in a going-first five-card hand (Inferred), and the searchers Betrayal, Pax, Sophia, Stella and Elis make the first Exosister Xyz reachable on turn 1-2. Conversion is strong on paper because the Extra Deck holds several 2300-2800 ATK Exosister Xyz monsters that can double-attack and banish opposing cards. Survival is supported by 14 hand traps and several backrow answers (Ash, Ghost Ogre, Ghost Belle, Droll, Evenly Matched, Returnia, Vadis), which give the deck a plausible going-second plan, though no combo data exists to measure that. Structural power is not earned from the popularity of Exosister or the average of individual card scores; it comes from the engine and interaction system scored as a whole. The final score is capped sharply because the list is Illegal (three cards over their copy limits, 60 main cards with 15 Extra), so this is a theoretical structural read only.

Dimension scores

How the score was computed

Strategy profile: Combo primary, Stun secondary, both stated by strategy; structural weights taken from Combo profile. Structural ≈ 67.7, Going First ≈ 70, Going Second ≈ 66, Meta = provisional, Tournament Reliability ≈ 55. Modifiers: banlist exposure (-8); off-archetype dead slots (-2). Final formula: Structural 67.7 with 0.80*Structural + 0.20*TournamentReliability = 65.2, plus context modifiers -10 = 55.2, then capped to 40 because the deck is Illegal (theoretical/structural-only). Meta Power is provisional (null).

Probability & combo summary

• Opening a starter: P(≥1) ≈ 0.95 · 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

• Archetype core present at about 95% in a going-first five-card hand (Inferred)
• Multiple searchers and Exosister draw/summon engines give redundant starters
• Layered hand traps and backrow answers (Ash, Ghost Ogre, Ghost Belle, Droll, Evenly Matched, Solemn Warning)
• Xyz Extra Deck has strong 2300-2800 ATK double-attack and banish monsters

Weaknesses

• Illegal list: three cards over their copy limits
• Extra Deck is 15 Xyz with no side deck, so there is no post-side adaptation
• Roughly 57% of the main deck is off the exact Exosister name, with dead-in-hand tech and Sphere Mode
• No recorded boards, so the combo floor and median are unknown

Critical choke points

• Exosister monster count in hand: a hand with no Exosister starter or searcher loses the engine
• Xyz material requirement: needs two Exosister monsters on board to Xyz Summon the top-end Extra Deck monsters

Recommended changes

Evidence & confidence

• Verified: Main count 60 (legal range 40-60), Extra count 15 (legal range 0-15), Side 0 (legal range 0-15); Three copy-limit violations: Ash Blossom x3 (limit 2), Solemn Warning x3 (limit 2), Seventh Tachyon x2 (limit 1); Card text for hand traps, searchers and Xyz effects from the resolved card excerpts; Exosister archetype usage stat: Elis 93%, Martha 91%, Pax 86%, Betrayal 84% inclusion
• Inferred: Going-first at least one archetype core card 0.949 from hypergeometric draw model; Going-second hand-trap availability 0.813; Brick and dead-tech rate in hand (14 hand traps, 24 tech, 13 searchers); Ceiling and going-second board-breaking from card text only
• Provisional: Meta Power is null and Matchup Coverage is provisional: no dated metagame sample or tournament link; Tournament Reliability is estimated from text and draw odds, not from results
• 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/second, matchup, brick/starter/OTK rates) exists in YGOVN Meta Power is Provisional unless a dated metagame sample is supplied deck title is null in the export no side deck: post-side behaviour is unmeasurable
