Exosister Deck #708902 — Yu-Gi-Oh! Master Duel

Deck — Deck Power Evaluation

Final Contextual Deck Power: 30/100 (±10 · Confidence: Low)

• Primary strategy: Combo
• Secondary strategies: Midrange, Stun
• Format: master-duel

Legality

Main 40 / Extra 15 / Side 0 — status under the rules at evaluation time: Illegal. 2 violation(s).

Identity & game plan

• Win condition: Exosister Xyz boards (Magnifica, Mikailis, Karmael, Kaspitell) built from Exosister monsters, converting into double attacks and banish or board-removal effects; Extra-Deck boss Xyz from ZEUS or TY-PHON as a flex finisher, plus Exosister Vadis / Dominus Purge / Returnia interaction
• Turn 1 (going first): Open with Exosister Elis, Martha, or Pax, extend into an Exosister Xyz, and hold Ash Blossom and Ghost Belle to protect the line
• Turn 2 (going second): Use the 13 hand traps (Ash Blossom, Ghost Belle, Infinite Impermanence, Maxx C, Droll & Lock Bird) to stop the opponent's draw or search, then rebuild the Exosister board through the Graveyard
• Recovery: Re-summon Exosister monsters from the GY (Stella, Elis, Martha) and Xyz again, drawing with Irene and Sophia
• After siding: No side deck (0 cards); the list cannot adapt between games of a best-of-3 set

Why it scores here

The Structural score was computed on the Combo profile from the deck as a system. The Exosister engine opens on 3-copy starters (Elis, Martha, Pax, Betrayal, roughly a 34% chance of at least one in a 5-card opening hand), and the 13 hand traps give the going-second plan real interruption depth. The Extra Deck (Magnifica, Mikailis, Karmael, ZEUS, TY-PHON) gives the deck strong closing power once a board is established. Popularity, the archetype's usage share, and the presence of guides did not add points; no combo boards exist, so the combo dimensions rest on text inference. The score is capped at 30 because the list is Illegal (Called by the Grave and Dimension Shifter are Forbidden and over the copy limit), so this is a theoretical, structural-only read. Card scores were not averaged.

Dimension scores

How the score was computed

Strategy profile: Combo. Structural ≈ 56, Going First ≈ 58, Going Second ≈ 60, Meta = provisional, Tournament Reliability ≈ 45. Modifiers: banlist exposure (-12). Final formula: No reliable metagame: 0.80*Structural + 0.20*TournamentReliability + ContextModifiers = 0.80*56 + 0.20*45 - 12 = 42, then capped to 30 because the list is Illegal (theoretical/structural-only)

Probability & combo summary

• Opening a starter: P(≥1) ≈ 0.34 · 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 engine with 3-copy starters and recursion through Ichiki and Pax
• 13 hand traps give the going-second plan depth
• Strong Extra Deck closing power from Magnifica, ZEUS, and TY-PHON

Weaknesses

• Illegal list: two Forbidden cards run at 1 copy each
• Only 52.7% exact archetype-name purity, with 26 off-archetype copies
• No side deck, so no post-side adaptation
• Martha and multi-step Xyz sequencing raise pilot difficulty

Critical choke points

• Exosister monster density on the field, because most Exosister engines require another Exosister monster
• Forbidden Called by the Grave and Dimension Shifter must be removed before the list can be scored normally

Recommended changes

Evidence & confidence

• Verified: Legality: Called by the Grave and Dimension Shifter are Forbidden with legal copies 0; Main 40 / Extra 15 / Side 0 composition; Extra Deck attack values; Archetype purity 52.7%
• Inferred: Starter and hand-trap consistency from the hypergeometric estimates; Interaction and combo-conversion reads from card text
• Provisional: Meta and matchup fit (no tournament link or dated sample)
• 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, going-second, and matchup rates are Unknown Meta Power is Provisional unless a dated metagame sample is supplied Usage statistics mark Exosister Karmael and Exosister Gibrine as in this deck:false, but the card list runs 2 Karmael and 1 Gibrine; the two sources disagree Title is null
