I've not tested it but it's a rare occasion when you'll have three cards you'd want. More often than not the third card that you'd draw would be Alexa or something it would seem. That's not worth 60 gems. At this point in my game it's not even worth 10 gems to flip if I'm showing Adamanti and Blood. With Tavern Tuesday I'll just spend all my credits on spirits and get the card for free in two weeks time.
