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

Legality

Main 40 / Extra 15 / Side 0 — status: Legal.

Identity & game plan

• Win condition: Xyz Summon a 2500-2900 ATK boss (Magnifica, Mikailis, Karmael, TY-PHON) from Exosister monsters, then keep banish/negate pressure on the board; Fusion/Synchro routes via Albion and Ecclesia, plus Exosister Pax and Betrayal searches into the Xyz line
• Turn 1 (going first): Open with one of 8 Exosister special-summon starters (Elis, Martha, Stella), search or summon a second Exosister, then Xyz Summon a 4-rank boss
• Turn 2 (going second): Hold hand traps (Ash Blossom, Infinite Impermanence, Ghost Ogre, Effect Veiler, Maxx C) to stop the opponent's first board, then rebuild the Exosister Xyz line from the GY and Extra
• Recovery: Spend Ghost Mourner and Ghost Ogre to protect the board, recover starters via Betrayal/Irene/Sophia draws, and re-Xyz from the field
• After siding: No side deck is registered, so there is no measured post-side plan

Why it scores here

The deck opens a functional plan through eight Exosister special-summon starters (Elis, Martha, Stella), which gives roughly a 69% chance of at least one in a going-first 5-card opener (Inferred). It converts that plan into Xyz pressure with 13 Xyz boss options at 2500-2900 ATK, including Magnifica and Mikailis, and it keeps its own board alive with 11 hand traps and Maxx C, with about 88% chance of at least one hand trap in a going-second 6-card hand (Inferred). Its weaknesses are the lack of a side deck, 49% exact-name archetype purity with 28 off-archetype copies, and the absence of recorded boards, so the ceiling and median are text-based estimates. Popularity and archetype usage stats confirmed that the list is a real, accessible build but earned no points on their own, and no card scores were averaged into this deck score.

Dimension scores

How the score was computed

Strategy profile: Midrange. Structural ≈ 61.7, Going First ≈ 62, Going Second ≈ 66, Meta = provisional, Tournament Reliability ≈ 55. Modifiers: banlist exposure (-1); no side deck (-2). Final formula: 0.80*Structural + 0.20*TournamentReliability + ContextModifiers (Meta provisional): 0.80*61.7 + 0.20*55 - 3 = 57.4 -> 57

Probability & combo summary

• Opening a starter: P(≥1) ≈ 0.69 · 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

• Eight conditional special-summon starters with a 29-copy archetype core make the first Xyz line likely
• Eleven hand traps give strong going-second interaction
• Xyz ceiling of 2500-2900 ATK with banish/negate on Magnifica and Mikailis
• Legal list at copy limits with a full 15-card Extra Deck

Weaknesses

• No side deck, so no post-side adaptation
• Only 49.1% exact-name archetype purity; Branded, Mulcharmy, Ecclesia and Seventh dilute engine coherence
• Pax costs 800 LP and several lines require an Exosister monster on the field
• No recorded boards, so ceiling and median are text-based inferences

Critical choke points

• Opening hand with none of 8 starters (about 31% going first) has no Xyz line
• Exosister Xyz needs Exosister materials; hands of hand traps and off-archetype cards brick

Recommended changes

Evidence & confidence

• Verified: Legal list: 40 main, 15 extra, 0 side; Maxx C 1/1 Limited; Fallen & Virtuous 2/2 Semi-Limited; Archetype composition: 49.1% exact-name purity, 13 Xyz in Extra; Xyz ATK/DEF stats and hand-trap count from card data
• Observed: Archetype usage stats: 25 core cards, 14 present in this list
• Inferred: Starter probability ~0.69 going first, ~0.76 going second; Engine accessibility and brick-rate estimates; Combo ceiling and floor from card text only; Negation and removal reads from card text
• Provisional: Meta power and matchup fit (no dated meta sample); Post-side plan (no side deck)
• Data gaps: No combos supplied: combo floor/median/ceiling is text-only inference No tournament link: archetype meta-share and per-pilot match record absent No win-rate telemetry: going-first/second, matchup and brick/starter rates are Inferred Meta Power is Provisional without a dated metagame sample Side deck empty: no post-side evidence
