Who do I rank up?

MountainDew69

I have too many mystic catalysts in overflow so I have to rank someone up. Should it be 5 star Ebony Maw, 4 star duped Hood, 4 star duped mordo, 4 star mephisto or 4 star dormammu. I'm on 5.3.1 so I do need decent mystics

Ebony maw. 5 stars are more useful even if he is trash
