I don't know if it's enough to save any of these, but single coin flip cards aren't really 50/50 odds. With a little knowledge and a little practice, you can get much better odds than that on the manual first flip, which is the only one that matters for a lot of those kinds of cards.
It turns it from a random chance to a dexterity game, and I don't like it because that's not what I'm here for, but it is what it is.
