Exosister Deck #773375 — Yu-Gi-Oh! OCG

Deck — Deck Power Evaluation

Final Contextual Deck Power: 64/100 (±6 · Confidence: Medium)

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

Legality

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

Identity & game plan

• Win condition: Xyz Summon Exosister Xyz monsters (Magnifica, Karmael, Mikailis, Kaspitell) from the Extra Deck via Exosister engine monsters, then attack and use Xyz removal/negation to clear the way.; Dominus-based interaction and Exosister Betrayal/Pax/Vadis recursion into the Xyz plan, with the hand traps keeping the opponent off the board.
• Turn 1 (going first): Open with Exosister Elis/Martha/Stella or Betrayal to search and summon a second Exosister, then Xyz Summon a Rank 4 Exosister Xyz monster; hold Ash/Impermanence for the response when possible.
• Turn 2 (going second): Use a hand trap (Ash Blossom, Ghost Ogre, Droll & Lock Bird, Maxx "C") or Dominus Spark/Purge on the opponent's first meaningful play, then rebuild the Exosister board from the Deck.
• Recovery: Exosister monsters and spells recycle themselves from the GY and banish/Deck effects, and Irene and Vadis return cards to the Deck to refill the hand.
• After siding: No Side Deck is registered (side_count 0); no post-side plan can be evaluated from this list.

Why it scores here

The deck reliably opens its engine: 25 archetype-core copies give a 99.5% chance of at least one Exosister card in an opening five, and 12 searchers give about 85% for at least one searcher, so the Exosister chain is usually live by turn 1-2. Conversion rests on a 15-card Xyz Extra Deck with several 2500-2800 ATK Xyz monsters, which lifts the ceiling; no boards were supplied, so that ceiling is read from card text and marked Inferred. Interaction is broad (8 hand traps, Dominus Spark/Purge, Returnia, Gibrine/Magnifica removal text), which earns the endboard and going-second scores and gives the deck its layered route redundancy. Popularity did not earn points: the archetype core's high usage only confirms the list is real and accessible, and the score was built from the system's consistency, median output, and interaction rather than averaging card scores. Missing combos, tournament data, and any side deck cap confidence and pull the final toward the middle.

Dimension scores

How the score was computed

Strategy profile: Primary Combo weighted 100%; Midrange used only as the secondary label, not in the score. Structural ≈ 68, Going First ≈ 66, Going Second ≈ 66, Meta = provisional, Tournament Reliability ≈ 62. Modifiers: banlist_exposure (-1); engine_conflicts (-1); no_side_deck (-2); interaction_density (2). Final formula: 0.80*Structural + 0.20*TournamentReliability + ContextModifiers (Meta provisional, no dated metagame sample)

Probability & combo summary

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

Strengths

• Dense archetype core (25 copies) gives near-certain starter access
• Layered interaction across hand traps, Dominus cards, and Xyz removal
• Strong Rank 4 Exosister Xyz end-board with second-attack and ATK pressure

Weaknesses

• No side deck, so no post-side adaptability
• Several Limited and Semi-Limited cards at their maximum, exposed to banlist changes
• Martha and Elis have conflicting summon conditions that can brick the opening hand

Critical choke points

• The Exosister Xyz-material chain: if the first Exosister monster is dead or the Xyz target is removed, the end-board stalls
• Limited cards Droll, Maxx C, and Seventh Tachyon are one copy each, so losing one removes that layer for the match

Recommended changes

Evidence & confidence

• Verified: Legal for OCG, 40 main / 15 extra / 0 side, no violations; Banlist status: Droll & Lock Bird, Maxx "C", Seventh Tachyon Limited; Ash Blossom and K9-17 Izuna Semi-Limited, all at legal maximum; Card text and stats for the listed Exosister, Dominus, and Xyz cards; Archetype usage: Exosister core inclusion rates from usage_statistics
• Inferred: P(>=1 starter in opening 5) ≈ 0.995 from the hypergeometric proxy; Going-second hand-trap access ≈ 0.76; Combo ceiling and median from card text, with no boards recorded; Interaction and resilience scores from role tags and card text
• Provisional: Meta Power (no dated metagame sample); Matchup and format-fit score (D13)
• Data gaps: No combos supplied: combo floor, median, and ceiling are text-only inference No tournament link: archetype meta-share and per-pilot record are absent No win-rate telemetry exists in YGOVN, so going-first/second and matchup rates are unknown Meta Power is provisional without a dated metagame sample No side deck was registered, so D12 has no list to evaluate Data inconsistency: Divine Arsenal AA-ZEUS - Sky Thunder appears in cards (zone extra, copies 1) but its usage_statistics entry reports in_this_deck false; the evaluation counts it as present because the Extra count of 15 requires it Usage-stat core list includes Exosister Karmael, Magnifica, Kaspitell, Gibrine, Mikailis, Asophiel, and Super Starslayer TY-PHON as missing, so the list deviates from the archetype core
