I know there is a lot of posts about this but I am still confused, as of my current team I am doing fine but not optimal, so my question is "who would be more useful to me aviete or setzer?" I currently have 3.5k rubies as I made a foolish mistake and pulled xerc on mehrez didn't know that he will be on aviete's banner, but I heard that there is a 10 pull that 50% can give me setzer, so should I get to 4.5k and pull for aviete and hope for the best for setzer? Or what? Also I heard edgar is an upgrade for signa whom I lack, so that's another factor I didn't account for yet
