Who to use a 3* Mystic awakening Gem on?

I have Ghost Rider, Dormammu, Diablo, and Mephisto. Should I use on one of them or wait till I get Ebony Maw?

Dont use it until you get a doc voodoo, and besides you get dupes for 3* very fast so you shouldent worry about it yet just save it

GR is definitely worthy of that as a 3*. Might as well use it as you'll have a 4* roster before you know it.

Just don't use it on Diablo and it'll be good

One of the most disappointing mystics in the game. Perhaps only Unstoppable Colossus is worse than him.
