Deck — Deck Power Evaluation

Final Contextual Deck Power: 59/100 (±6 · Confidence: Medium)

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

Legality

Main 42 / Extra 15 / Side 0 — status: Legal.

Identity & game plan

• Win condition: Exosister Xyz boss (Karmael, Kaspitell, Mikailis, Asophiel, Gibrine, Magnifica) summoned through Exosister monster triggers and opponent GY movement; Level 4 Xyz pressure from Number 104 Masquerade and Magnifica second attack; Fusion/Synchro/Xyz 12 boards are off-plan
• Turn 1 (going first): Turn 1: Martha or Elis from hand, search or Special Summon the next Exosister via Pax, Betrayal or Stella; build a Level 4 Xyz using Exosister monsters and protect the board with Ash Blossom, Maxx C or Droll
• Turn 2 (going second): Turn 1 Ash Blossom, Droll, Maxx C or Ghost Ogre/Belle/Mourner on the opponent's summon or activation, then Elis/Martha recovery and Xyz into Karmael or Kaspitell
• Recovery: Exosister Betrayal, Irene and Sophia rebuild hand and monsters; Pax and Returnia cost 800 LP each and are the recovery valves; Seventh Tachyon and Number 104 supply a second Xyz route
• After siding: Not applicable: Master Duel is single-game with no side deck; no post-side plan exists (Provisional)

Why it scores here

This Exosister list reliably opens a live engine: 28 core Exosister copies give P(at least one in a 5-card opening hand) of about 0.998, and Elis, Martha, Pax and Betrayal supply repeatable access to the monsters that feed the Xyz triggers. Its consistency comes from the system, not from a sum of card scores: the search and summon engine, the Xyz route through opponent GY movement, and an interaction suite of eight hand-trap or tech cards (Ash x3, Droll x2, Maxx C, Ghost Ogre, Ghost Belle, Forbidden Droplet) form one coherent plan. Its conversion is solid but unmeasured because no recorded boards exist, so the ceiling rests on card text and Level 4 Xyz bosses in the 2500 to 2800 ATK range. Its weak points are the Branded/Albaz/Ecclesia extra slots and the Level 12 Xyz pair, which have no support in the main deck and count as dead slots. Popularity and archetype usage confirm the list is real and accessible but earned no points, and no meta-share was credited.

Dimension scores

How the score was computed

Strategy profile: Midrange profile with D13 dropped and renormalised over remaining weights (meta-neutral structural). Structural ≈ 63, Going First ≈ 64, Going Second ≈ 66, Meta = provisional, Tournament Reliability ≈ 56. Modifiers: engine conflicts (Branded, Albaz and Ecclesia extra slots without Fallen of Albaz) (-3). Final formula: 0.80*Structural + 0.20*TournamentReliability + ContextModifiers (Meta provisional; Structural = 6024/95 = 63.4 with D13 dropped)

Probability & combo summary

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

Strengths

• Core Exosister engine is almost always accessible in an opening hand
• Eight hand-trap or tech cards plus Ash x3 give dense interaction on both turn orders
• Multiple independent recovery routes through Betrayal, Irene, Sophia and Pax

Weaknesses

• Five Extra-Deck copies (Albion, Dragon Devours Dogma, Ecclesia, AA-ZEUS, TY-PHON) lack support from the main deck
• Several conditional main-deck cards (Ichiki Sayori-Hime, Triple Tactics Talent, Mulcharmy) raise brick risk
• Pax and Returnia cost 800 LP each, limiting repeated use

Critical choke points

• Martha summon restriction limits monster deployment when the field holds non-Xyz monsters
• Xyz triggers depend on the opponent moving cards out of the GY

Recommended changes

Evidence & confidence

• Verified: Main 42, Extra 15, Side 0 within Master Duel size rules; Legal status: Maxx C at 1 copy (Limited), Droll and Fallen and Virtuous at 2 copies (Semi-Limited); Exact Exosister name purity 43.9 percent (25 of 57)
• Inferred: P(at least one core Exosister in a 5-card opener) about 0.998; Going-second hand-trap P(at least one in 6) about 0.74; Interaction density high from card text (Ash, Droll, Maxx C, Ghost Ogre, Ghost Belle, Droplet, Crown, Rai-Oh); Five Extra-Deck copies are dead or near-dead without Albaz or Level 12 monsters
• Provisional: Median output and floor (no recorded boards); Matchup and format fit (no tournament link or dated meta sample); Post-side plan (Master Duel has no side)
• 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 usage statistics in this deck flags contradict cards[] for Extra-Deck cards (Karmael, Gibrine, Asophiel, Mikailis, Magnifica, Number 104, AA-ZEUS, TY-PHON, Albion, Ecclesia are present in cards[] but marked not in deck), so missing core cards is unreliable and was not used no win-rate telemetry: going-first, going-second, matchup and brick rates are Inferred or Unknown Meta Power provisional: no dated metagame sample supplied deck title is null
