Going for uncollected

Crisonix13

Hello, i am currently stuck at 5.1.6 i do think this is enough but im legit getting one shot everytime maybe I just suck XD. Is my champions actually enough or bit weak? I see people going uncollected with 4 stars only only difference is they are duped. If its too weak would like to ask if should I level up other units? cause I can finish act 4 and get the awakening for Corvus or Stryfe.

I think ranking up corvus would be a good idea
