Hey guys! I was at 5.4.1, which champs will help me against the Ultron boss at 5.4.4, u can see my roster. I was thinking to rank up guardian thought that he would help me a lot and for Ultron some guys tell me that medusa and V aarkus will help but I have them at 4* I can even rank them up but when I was using aarkus I feel my device get lagging. Also I know to use quake and Spidey 2099, I have r5 doom, human torch, 6* R1 gully 2099, mr.fantastic , r4 gwenpool, r3 kitty pryde. So give it valuable suggestions for me. Thanks in advance.
