Exosister Deck #647774 — Yu-Gi-Oh! TCG

Deck — Deck Power Evaluation

Final Contextual Deck Power: 30/100 (±8 · Confidence: Low)

• Primary strategy: Midrange
• Secondary strategies: Toolbox, Stun
• Format: tcg

Legality

Main 40 / Extra 15 / Side 0 — status: Illegal. 6 violation(s).

Identity & game plan

• Win condition: Xyz Summon Exosister Xyz monsters (Karmael, Mikailis, Magnifica, Kaspitell) from the Extra Deck and convert the board with 2500+ ATK attackers; Off-archetype Xyz finishers (Super Starslayer TY-PHON, Evilswarm Exciton Knight) and Exosister Vadis/Returnia banish-based removal
• Turn 1 (going first): Open Exosister monsters (Elis, Martha, Stella, Sophia, Irene), use Betrayal or Pax to search a second Exosister, Xyz Summon a 2500+ ATK boss, and protect it with Ash Blossom and Infinite Impermanence
• Turn 2 (going second): Hold Ash Blossom, Droll & Lock Bird and Infinite Impermanence for the opponent's first search, Special Summon through Exosister effects, and Xyz into a boss before the opponent's board develops
• Recovery: Recover through Pax, Betrayal and Stella/Elis searches and Exosister monsters in the GY; Xyz Import is the only other interaction for the rebuild
• After siding: No Side Deck is registered, so there is no post-side plan; the deck would need a 15-card Side Deck to adjust

Why it scores here

The deck reliably opens a live Exosister starter: the archetype core is about 98% likely to have at least one piece in a 5-card opening hand (Inferred, hypergeometric), and nine searchers and summoners give several routes into the Extra Deck Xyz bosses. Its ceiling comes from 2500-2900 ATK Xyz monsters and a hand-trap suite of Ash Blossom, Infinite Impermanence and Droll & Lock Bird that can stop an opponent's first search or summon. Median output is unmeasured, because no recorded boards exist, and the 40-card main carries 12 tech slots, four Forbidden cards and a 40% off-name-purity share that reduces the consistency of the engine. The score is not driven by Exosister's popularity, and it does not come from averaging individual card scores. The list is Illegal under the TCG copy limits, so the Final Contextual score is capped at 30 and the structural read is theoretical only.

Dimension scores

How the score was computed

Strategy profile: Midrange. Structural ≈ 53, Going First ≈ 55, Going Second ≈ 45, Meta = provisional, Tournament Reliability ≈ 45. Modifiers: banlist exposure (-12). Final formula: Illegal cap: unconstrained 0.80*Structural(53) + 0.20*TournamentReliability(45) + Modifiers(-12) = 39; capped to 30 because the list breaks copy limits and Forbidden rules (Meta provisional)

Probability & combo summary

• Opening a starter: P(≥1) ≈ 0.98 · 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 is redundant: about 98% chance of at least one Exosister in a 5-card opening hand
• Multiple searchers (Betrayal, Pax, Stella, Elis, Sophia, Irene) give a stable route to Xyz material
• High-ATK Xyz finishers (Karmael 2600, Magnifica 2800, Mikailis 2500) and Ash/Droll/Infinite Impermanence interaction

Weaknesses

• Illegal under TCG copy limits: Ash Blossom 3 vs 2, Droll 2 vs 1
• Four Forbidden cards plus Pot of Prosperity (Limited) undermine the list's legality
• No Side Deck: 0 of 15 side slots used, so no post-side adaptability
• Off-archetype Extra Deck cards (TY-PHON, Bagooska, Evilswarm) dilute the engine (purity 60%)
• No recorded boards, so the combo ceiling and median cannot be verified

Critical choke points

• Opening hand needs an Exosister starter plus a searcher; Ash Blossom and Droll are the only answers to a first-turn interruption
• Xyz Summon of the boss depends on Extra Deck access; the Forbidden Crossout Designator and Called by the Grave cannot be run in this format

Recommended changes

Evidence & confidence

• Verified: Deck is Illegal: 6 copy-limit or Forbidden violations; main 40, extra 15, side 0; Archetype purity 60% (33 of 55 Exosister-named copies); 9 hand-trap cards in the main; Card texts and stats for the Exosister Xyz monsters (Karmael 2600, Magnifica 2800, Mikailis 2500)
• Observed: Usage statistics: 36 stat rows, 25 core cards for the archetype
• Inferred: Opening-hand consistency P(>=1 archetype core in 5) = 0.98 (hypergeometric); Interaction and brick-risk reads from card text; Going-first and going-second splits from the Midrange profile
• Provisional: Meta power (no dated metagame sample); Matchup and format fit (no tournament link)
• 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 for going-first, going-second, matchup, or brick and starter rates usage_statistics.core_cards marks Karmael, Mikailis, Magnifica, Kaspitell, Asophiel and Gibrine as in_this_deck=false and reports core_present_pct 36%, but the cards list has them in the Extra Deck (3, 3, 2, 2, 1, 1 copies); the core-presence calculation appears to ignore the Extra Deck, so the 36% figure is unreliable No Side Deck supplied, so post-side plan cannot be assessed
