Exosister Deck #770160 — Yu-Gi-Oh! OCG

Deck — Deck Power Evaluation

Final Contextual Deck Power: 35/100 (±8 · Confidence: Low)

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

Legality

Main 52 / Extra 18 / Side 0 — status: Illegal. 2 violation(s).

Identity & game plan

• Win condition: Xyz Summon high-ATK Exosister Xyz monsters (Mikailis, Magnifica, Karmael, Kaspitell) off the Exosister engine and push damage through board breaks; Hand-trap and negation control that leaves the opponent without a board, then a single Xyz finisher
• Turn 1 (going first): Normal Summon Exosister Stella or Elis and use the Exosister monsters' on-field and GY effects to set up an Xyz Summon; keep Ash Blossom, Infinite Impermanence or Effect Veiler up as interaction
• Turn 2 (going second): Hold Ash Blossom, Ghost Ogre, Effect Veiler, Droll & Lock Bird or Maxx C to answer the opponent's first board, then rebuild an Exosister Xyz from the hand
• Recovery: Exosister searchers (Betrayal, Pax, Sakitama, Sayori-Hime) and the Exosister GY revival effects are the recovery path; LP costs (800 each on Pax, Vadis, Returnia, Arment) limit how often it can be used
• After siding: Not evaluable: the export carries no side deck (side_count 0), so there is no post-side plan to score

Why it scores here

The Exosister core is dense and redundant: the archetype core group has a 0.98 hypergeometric chance of at least one copy in a 5-card opening hand (Inferred), and the engine opens from several separate starters. Its interaction suite (13 hand traps, about 12 negation and 12 removal text effects) makes it strong at answering the opponent's first board, especially going second (P of at least one hand trap in a 6-card hand is about 0.84, Inferred). The Extra Deck has real closing power (Magnifica 2800, Karmael 2600, Mikailis 2500 ATK), but no recorded boards exist, so combo ceiling and median output are text-based inference only. The score is not driven by Exosister being a popular archetype (usage stats are only context) and not by averaging card scores. The deck is scored as Illegal: a Forbidden card and an over-size Extra Deck cap the result at 35, and the structural read is theoretical only. No side deck was supplied, which removes the post-side dimension.

Dimension scores

How the score was computed

Strategy profile: Combo. Structural ≈ 56.2, Going First ≈ 58, Going Second ≈ 62, Meta = provisional, Tournament Reliability ≈ 48. Modifiers: banlist exposure (-8); no side deck (-4). Final formula: Illegal cap applied. Uncapped: 0.80*56.2 + 0.20*48 + (-12 modifiers) = 42.6, capped to 35 because the deck is Illegal (Forbidden card, Extra Deck 18 > 15). Meta Power 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

• Dense Exosister core with redundant starters (27 copies, 0.98 P(at least one in hand5))
• Strong interaction suite: 13 hand traps, about 12 negations and about 12 removal effects
• Extra Deck covers 2500–3000 ATK Xyz finishers

Weaknesses

• Illegal in OCG: Triple Tactics Talent is Forbidden and the Extra Deck is 18 against a 15 maximum
• No side deck; the post-side plan cannot be scored
• Only 45.7% exact-name archetype purity; 38 off-archetype copies dilute the engine

Critical choke points

• Single-copy Xyz finishers (Gibrine, Utopic Draco Future) depend on the engine reaching the right materials
• Triple Tactics Talent (Forbidden) must be removed before the list is legal

Recommended changes

Evidence & confidence

• Verified: Legality: Triple Tactics Talent is Forbidden (1 copy) and the Extra Deck is 18 against a 15 maximum; Copy limits met for all Limited and Semi-Limited cards; Archetype purity 45.7% and archetype composition by name; Extra Deck breakdown: 16 Xyz, 2 Link
• Inferred: Core-group opening probability 0.98 and single-starter odds; Hand-trap and negation coverage from card text; Going-second interaction estimate of about 0.84 for one hand trap in hand6; Combo ceiling from text only (no recorded boards)
• Provisional: Meta Power (no dated meta 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 side deck in the export: post-side plan cannot be evaluated no win-rate telemetry in YGOVN (going first/second, matchup, brick and starter rates) Meta Power is Provisional unless a dated metagame sample is supplied
