Exosister Deck #769548 — Yu-Gi-Oh! OCG

Deck — Deck Power Evaluation

Final Contextual Deck Power: 59/100 (±7 · Confidence: Medium)

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

Legality

Main 45 / Extra 15 / Side 0 — status: Legal.

Identity & game plan

• Win condition: Xyz pressure from Exosister Xyz monsters (Magnifica, Karmael, Mikailis, Kaspitell) built off a chain of Exosister starters; Hand-trap disruption (Infinite Impermanence, Ash Blossom, Maxx C, Droll & Lock Bird) turning the opponent's interaction into a tempo window
• Turn 1 (going first): Open with an Exosister starter (Elis, Martha, Stella or Sophia) plus Betrayal or Pax to reach Exosister Xyz, using searcher and recursion text to keep a second line
• Turn 2 (going second): Hold a hand trap (9 copies, about 76% at least one in a 6-card hand) to break the opponent's first board, then rebuild through Exosister recursion and Xyz Summons
• Recovery: Recur Exosister monsters from the GY and banishment through Returnia, Arment and Vadis, and re-Xyz from the Extra Deck when the board is broken
• After siding: No side deck is registered, so there is no post-side plan in the list; any change would require a new build

Why it scores here

The deck reliably opens on Exosister starters: 30 Exosister-archetype copies give an archetype-core hypergeometric estimate near 0.997 of at least one in a 5-card opening hand, and 10 searcher-text cards give about 0.73 for at least one in hand. Conversion is judged from text only because no recorded boards exist, so Exosister Xyz pressure and the recursion lines are Inferred rather than observed. Interaction is the strongest part of the system: 9 hand traps and 4 removal-text cards give a going-second hand-trap chance of about 0.76. The Xyz end boards are real but the median output is unmeasured, and the score is not lifted by Exosister being a popular archetype or by averaging card scores. The deck runs no side deck and has no tournament or dated meta sample, so the final score is held near the middle of the range.

Dimension scores

How the score was computed

Strategy profile: Midrange primary with Stun-leaning interaction emphasis, about 80/20 by weight. Structural ≈ 63.4, Going First ≈ 66, Going Second ≈ 62, Meta = provisional, Tournament Reliability ≈ 58. Modifiers: banlist exposure (-1); no side deck (-2). Final formula: 0.80*Structural + 0.20*TournamentReliability (Meta provisional) + ContextModifiers(-3): 0.80*63.4 + 0.20*58 - 3 = 59.35, rounded to 59

Probability & combo summary

• Opening a starter: P(≥1) ≈ 0.3 · 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 dense and accessible: Exosister monsters are the majority of the Main Deck
• Layered interaction: 9 hand traps plus Ash Blossom, Impermanence and Returnia removal text
• Extra Deck is coherent around Exosister Xyz with several double-attack or board-breaking options
• Searcher and recursion text give more than one starting line

Weaknesses

• No side deck, so the list has no post-side adaptability
• Off-archetype slots (Chaos Angel, Zeus, Numeron, Bystial) dilute the engine
• LP-cost cards (Pax, Arment, Vadis, Returnia) tax the life total each turn
• No recorded boards or combo evidence to confirm the median output

Critical choke points

• Losing the first Exosister starter to hand trap or early disruption stalls the Xyz plan
• Limited singletons (Droll, Maxx C, Bystial Druiswurm, Bystial Magnamhut) are one-copy access points
• Xyz Summons depend on Exosister monsters being on the field at the right time

Recommended changes

Evidence & confidence

• Verified: Legal status: 45 Main, 15 Extra, 0 Side, all copy limits respected; Restricted cards: Druiswurm, Magnamhut, Droll & Lock Bird, Maxx C at 1 copy each (Limited); Ash Blossom at 2 (Semi-Limited); Archetype usage: Exosister core cards show 50-95% inclusion across 22 stat rows
• Observed: Usage statistics show the Exosister core is standard across the archetype
• Inferred: Consistency estimates from hypergeometric draw tables; Interaction and recursion quality from card text; Xyz end-board closing power
• Provisional: Meta Power is null: no dated metagame sample; Matchup and format-fit scores (D13) are provisional
• 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 and starter rates) exists in YGOVN Meta Power is provisional unless a dated metagame sample is supplied no side deck: post-side behaviour cannot be scored from performance data
