Exosister Deck #769357 — Yu-Gi-Oh! OCG

Deck — Deck Power Evaluation

Final Contextual Deck Power: 25/100 (±8 · Confidence: Low)

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

Legality

Main 41 / Extra 15 / Side 0 — status: Illegal. 2 violation(s).

Identity & game plan

• Win condition: Xyz Summon high-ATK Exosister Xyz monsters (Mikailis, Magnifica, Karmael, Kaspitell) off recurring Exosister material; Divine Arsenal AA-ZEUS and Super Starslayer TY-PHON as late-game boss Xyz, with Exosister Gibrine and Asophiel as board-control bosses
• Turn 1 (going first): Open on Exosister Elis, Martha, Pax, Betrayal, or Stella to put Exosister monsters onto the field, then Pax or Betrayal to search and Xyz Summon a boss from the Extra Deck
• Turn 2 (going second): Use Ash Blossom, Maxx C, or Returnia to stop the opponent's first summon or board, then rebuild the Exosister board with Irene, Sophia, and Stella and Xyz Summon through the interaction
• Recovery: Recover through the Exosister GY recursion effects on Elis, Martha, and Sophia, plus Mikailis and Magnifica's material-based effects
• After siding: Not evaluable: the deck has no side deck (side_count 0), so no post-side plan exists in the export

Why it scores here

The deck's engine is reliable on paper: 21 archetype-core copies give a hypergeometric P(at least one core card in a 5-card opener) of about 0.98, and Elis, Martha, Pax, and Betrayal each have about a 0.33 chance of appearing in the opener. The Extra Deck has 13 Xyz monsters with 2500 to 3000 ATK, which gives the deck closing power, and the Exosister material loop provides recursion. Interaction is real but thin: Ash Blossom, Maxx C, Ultimate Sky, Returnia, and Dominus Spark cover the main interruption points. The score does not come from Exosister being a popular archetype or from averaging card scores. Because the list is Illegal (two Forbidden cards and two copy-limit violations), the structural score is capped at 25 and is shown for theory only, with a banlist exposure modifier applied. No combo boards or matchup data exist, so the floor, median, and matchup dimensions are provisional.

Dimension scores

How the score was computed

Strategy profile: Midrange primary with Combo as a secondary read; no separate weight vector was applied. Structural ≈ 56, Going First ≈ 55, Going Second ≈ 55, Meta = provisional, Tournament Reliability ≈ 45. Modifiers: banlist exposure (-12). Final formula: Illegal cap: 0.80*Structural(56) + 0.20*TournamentReliability(45) = 54 before modifiers; banlist exposure −12 gives 42; final score capped at 25 because the list is Illegal. Score is theoretical/structural-only. Meta provisional.

Probability & combo summary

• Opening a starter: P(≥1) ≈ 0.98 · key two-card combo ≈ — · full-brick estimate ≈ 0.02 (all Inferred)
• Combo output: best PowerIndex —, median —, board-per-starter —
• Turn order: 0 going-first lines vs 0 going-second lines

Strengths

• Archetype-core density (21 copies) gives strong opening access to the engine
• High-ATK Xyz bosses (2500 to 3000) give the deck real closing power
• Multiple hand traps and negation-text cards cover common interruptions

Weaknesses

• Two Forbidden cards and two copy-limit violations make the list illegal as built
• No side deck, so there is no post-side adaptation
• High LP cost across several cards strains the resource curve

Critical choke points

• Pax and Betrayal are the main search engines; losing them to hand disruption removes the main route to the boss
• Forbidden Albion and Triple Tactics Talent occupy slots that a legal list would need to fill

Recommended changes

Evidence & confidence

• Verified: Main 41 (within 40–60); Extra 15 (within 0–15); Side 0 (within 0–15); Albion and Triple Tactics Talent are Forbidden, with legal_copies 0; Maxx C and Seventh Tachyon are Limited at 1 copy each; Ash Blossom and Fallen & Virtuous are Semi-Limited at 2 copies each; Extra Deck stats for Magnifica, Karmael, Mikailis, TY-PHON, and ZEUS
• Inferred: P(at least one core card in opener) ≈ 0.98; Structural estimate of 56 across the 14 dimensions; Confidence rests on text and probability only, with no combo data
• Provisional: Meta power is null: no dated metagame sample; Tournament reliability of 45 is an estimate; Matchup fit is unverified
• 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 exists in YGOVN: going-first, going-second, matchup, and brick rates are Inferred no side deck: post-side adaptability cannot be measured Meta Power is provisional unless a dated metagame sample is supplied
