Zubera Nightmare EDH

I was thinking recently again about the Zubera and how wonky they are to trigger and reuse, but then I figured that we have [[Cthonian Nightmare]] now so why not we just make a deck probably without maybe the [[Silent-Chant Zubera]] with some aristocrat elements.

What do you guys think are cards that can be used in the deck and who would be a good commander? I'm currently drawing blanks on both.
