Arisa_malka1

Hey!
All of the following champions are 6*, unawakened and currently level 1. I have the resources to rank up 2 of them. Who should I rank up and why?

The options are:
Red Goblin
Ebony Maw
Proxima Midnight
Nick Fury
Gwenpool
Spot
Luke Cage

Thanks!

nick and spot are the best two options here
