Which champ to r2 unduped?

I run full suicides. Casual alliance. Map 2 only and war isn't super serious either. For monthly EQ and Act 6 who would be worth taking up?

Depends on which 5*s you are having.
If you're having better options in 5* then go for them.

Killmonger, Nebula or War Machine , Symbiote Supreme

I have a pretty ridiculous 5* roster. Lots of amazing champs. At least 10-15 more I need to r5.
