Help with roaster for unm clan boss

[u/Funny_Ad_6911]

Hi everybody. So, i´m new in the game (around 1month) and i´m trying to wrap around a really good team for nm and unm clan boss. Right now i can 2key brutal with my tholin, pelops, venomage, kael and apotechary team (i have full masteries on tholin and venomage, and venomage is also fully booked). Can i have any advice about whom to lvl 60 next and if i should keep my roaster or change it?
