Exosister Deck #770784 — Yu-Gi-Oh! OCG

Deck — Deck Power Evaluation

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

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

Legality

Main 55 / Extra 15 / Side 0 — status under the rules at evaluation time: Illegal. 1 violation(s).

Identity & game plan

• Win condition: Exosister Xyz boss (Exosisters Magnifica, Exosister Karmael, Exosister Mikailis) built from Exosister Elis/Martha/Pax/Betrayal starters, with Xyz summons from the Extra Deck; Divine Arsenal AA-ZEUS and Super Starslayer TY-PHON as single-card closers, not part of the core engine
• Turn 1 (going first): Open Exosister starters (Elis, Martha, Pax, Betrayal); a Pax or Betrayal line into an Xyz boss, with hand traps and Ash Blossom held up for the opponent's first activation. The opening-hand chance of a starter is about 0.25 per 3-copy card at hand size 5 (Inferred).
• Turn 2 (going second): Use the going-second hand (6 cards) to hold up hand traps (Infinite Impermanence, Evenly Matched, Ash Blossom, Dominus Purge) against the opponent's first board, then rebuild through Exosister Pax or Betrayal into an Xyz (Inferred).
• Recovery: Recursion and extension come from Exosister Gibrine/Asophiel-style Xyz text and the Exosister searchers (Betrayal, Irene). Recovery quality is text-only because no combo boards were supplied (Inferred).
• After siding: No side deck is registered (side_count 0), so no post-side plan can be evaluated. Best-of-3 play is unsupported by this list (Verified).

Why it scores here

The deck opens a starter reasonably often: the 28 archetype-core copies give a 0.98 chance of at least one core card in a 5-card opening hand, but the four-card starter set (Elis, Martha, Pax, Betrayal) has only about a 0.25 chance per 3-copy card (Inferred). Interaction is dense, with 9 hand traps, 18 negation-text cards and 15 removal-text cards, which earns the interaction and going-second dimensions. The Extra Deck has real Xyz coverage (Magnifica, Karmael, Mikailis, Kaspitell), but there are no recorded combo boards, so the ceiling and median are text-only estimates. Off-archetype copies (40 of 55 Main Deck slots) and the 18 tech cards pull down consistency and efficiency, and the lack of any side deck caps adaptability. Popularity (archetype usage stats) confirms the list is real, but it did not earn points. The score was not an average of card scores. The deck is Illegal (Ash Blossom run at 3 copies, limit 2), so the normal Final Contextual formula was capped to a low structural-only read.

Dimension scores

How the score was computed

Strategy profile: Combo. Structural ≈ 52.4, Going First ≈ 45, Going Second ≈ 55, Meta = provisional, Tournament Reliability ≈ 42. Modifiers: banlist exposure (-6); hard-garnet burden (-3); weak post-side plan (-3). Final formula: No reliable metagame: 0.80*Structural + 0.20*TournamentReliability + modifiers = 0.80*52.4 + 0.20*42 - 12 = 38.3 uncapped; Illegal deck capped to 30 (structural-only read)

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 hand-trap and negation package: 9 hand traps, 18 negation-text cards and 15 removal-text cards
• Real Xyz endboard: Magnifica, Karmael, Mikailis and Kaspitell with 2500-2800 ATK bodies
• High archetype-core presence: 28 copies, 0.98 chance of at least one in hand5

Weaknesses

• Illegal list: Ash Blossom & Joyous Spring run at 3 copies against a limit of 2
• Low exact-name purity (42.9%) and 40 off-archetype slots dilute the engine
• No side deck registered, so no best-of-3 adaptation

Critical choke points

• Pax or Betrayal as the only route to the Xyz boss, with no verified second line
• Ash Blossom and the hand traps must be kept in hand; an opponent's first board can break the line

Recommended changes

Evidence & confidence

• Verified: Main Deck 55 and Extra Deck 15 are within the OCG size rules; Ash Blossom & Joyous Spring is Semi-Limited with 3 copies run against a limit of 2; Extra Deck is all Xyz (15 cards) with 10 distinct; side_count is 0
• Observed: Exosister archetype usage stats: core cards at 75-94% inclusion
• Inferred: Starter opening-hand odds from hypergeometric estimates; Interaction density from text tags and excerpts; Going-first and going-second estimates
• Provisional: Meta power and matchup fit: no tournament link or dated metagame
• 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 in YGOVN (going-first/second, matchup, brick and starter rates) Meta Power is Provisional unless a dated metagame sample is supplied no side deck registered: post-side plan cannot be evaluated
