The Nemesis class deck allows you earn 1 imperial villain and 1 mercenary villain.
So the question is simple, what villains do you choose?
To me, I see 2 main options for the imperial villain: Grand Inquistor, if you want a straight-up badass villain or Kayn Somos, you wanted to focus on the "buffing your units" aspect of the deck (Ringleader, Devastating Legion, etc). Although I could see a case being made for Agent Blaise or Captain Terro
If you are playing any campaign other than Jabba's Realm, Jabba would be my #1 pick. But in the current campaign, Bossk seems best to me. Tho you can make a case for Dengar and Boba Fett (His main problem is you wouldn't really be able to bring him out until the latter part of the game)
Thoughts?
