I tried out making an Earth Rite deck and it's fucking stupid what they did with Juno. I played Juno and evolved her, gaining the crest. Next turn, I played another Juno and evolved her as well and it just refreshed the cooldown on my existing Juno crest instead of adding a second one. That's fucking retarded. I guess they're scared of people duping crest effects so they futureproofed it so you can't stack multiple of the same crests.
