Exosister Deck #771013 — Yu-Gi-Oh! OCG

Deck — Deck Power Evaluation

Final Contextual Deck Power: 61/100 (±6 · Confidence: Medium)

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

Legality

Main 56 / Extra 15 / Side 0 — status: Legal.

Identity & game plan

• Win condition: Xyz Summon an Exosister boss (Magnifica, Karmael, Kaspitell, Mikailis) from Exosister monsters and attack through a board the opponent cannot easily rebuild; Non-Exosister boss (Number 104, AA-ZEUS, TY-PHON) when the Exosister engine is interrupted
• Turn 1 (going first): Open Elis/Martha/Pax/Betrayal to set up an Exosister Xyz line, backed by Solemn and Ash Blossom to protect the T1 engine
• Turn 2 (going second): Use hand traps (Ash Blossom, Ghost Ogre, Infinite Impermanence, Droll and Lock Bird, Maxx C) and Solemn/Dominus Purge to break the opponent's board, then Xyz Summon from the Extra Deck
• Recovery: Recover through Exosister Pax and Exosister Betrayal (search/recursion), Irene and Sophia draws, and Mulcharmy monsters if the hand empties
• After siding: No side deck is registered, so there is no post-side plan; best-of-3 adaptation is unavailable as built

Why it scores here

The deck reliably opens its engine: Exosister Elis and Martha (6 copies between them) plus Pax and Betrayal give several independent T1 starters, and the archetype core is present in about 97% of opening hands (Inferred). Its interaction is layered, with 9 hand traps and about 18 negation-text cards, so it can survive a common disruption and still reach an Xyz boss from the Extra Deck. Conversion depends on the Extra Deck's 2500+ ATK Exosister Xyz bosses, which give a strong closing and board-breaking profile, but no recorded boards exist, so the ceiling and median are text-based inference only. The score comes from consistency, redundancy, interaction and closing power on the system; it does not come from Exosister's popularity, and card scores were not averaged. Scoring is held back by the empty side deck, the 42 off-archetype copies (40.8% exact-name purity), high Life Point costs (Pax, Solemn cards, Ultimate Sky) and the complexity of its Xyz chains.

Dimension scores

How the score was computed

Strategy profile: Combo. Structural ≈ 66.7, Going First ≈ 69, Going Second ≈ 70, Meta = provisional, Tournament Reliability ≈ 58. Modifiers: banlist_exposure (-2); archetype_purity_and_engine_conflicts (-2). Final formula: 0.80*Structural + 0.20*TournamentReliability (Meta provisional) + ContextModifiers(-4) = 0.80*66.7 + 0.20*58 - 4 = 60.96, rounded to 61

Probability & combo summary

• Opening a starter: P(≥1) ≈ 0.45 · 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

• Redundant Exosister starters (Elis, Martha, Pax, Betrayal, Stella, Ichiki) keep the engine reachable from many openings
• Layered interaction: 9 hand traps, 3 Solemn cards, 3 Dominus Purge and Infinite Impermanence x3
• Strong Xyz bosses (2500-3000 ATK) with Extra Deck coverage of 14 Xyz and 1 Link

Weaknesses

• No side deck, so no best-of-3 adaptation
• 40.8% exact-name archetype purity: 42 off-archetype copies dilute the engine
• High Life Point costs (Pax 800, Solemn Accusation 1500, Solemn Warning 2000, Ultimate Sky 800 per target) make grind and recovery expensive

Critical choke points

• Elis and Martha (6 copies) are the main T1 starters; a hand without them relies on Stella (2) and Sophia (1)
• Solemn Judgment and Maxx C are single copies; losing them weakens a key negation line
• Xyz bosses depend on Exosister monsters as material; a board wipe or hand-trap exchange can stall the chain

Recommended changes

Evidence & confidence

• Verified: Legal status: 56 main, 15 extra, 0 side, all copy limits respected (legality block); Banlist status for Limited and Semi-Limited cards and their legal copies (restricted_cards); Card stats and Extra Deck breakdown: 14 Xyz, 1 Link (composition, cards); Usage stat: Exosister core cards Elis (93.75%) and Martha (92.19%) are the most common core inclusions (usage_statistics)
• Inferred: Starter access: about 0.45 P(at least one of Elis or Martha in a 5-card opening) (hypergeometric); Going-second hand trap probability 0.67 and interaction density from card text; Brick risk from 42 off-archetype copies and conflicting Normal Summon routes; Structural and dimension scores (D1 through D14) from text and composition
• Provisional: Meta Power (null): no dated metagame sample supplied; Matchup and format fit (D13 = 50): no tournament link or archetype meta-share
• 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 and brick/starter rates are Inferred Usage statistics mark Extra Deck cards (Karmael, Magnifica, Kaspitell, Mikailis, Gibrine, Asophiel, AA-ZEUS, TY-PHON) as in_this_deck=false with copies_in_deck=0, although the card list runs them 1-3 copies each; the core-present count (13/21) is therefore understated and the extra-deck usage flags should be treated as unreliable No side deck (side_count 0): post-side and D12 are scored on the absence of a plan Meta Power is Provisional unless a dated metagame sample is supplied
