people doing addintional flips have a chance of getting a gold or a purple card there is no BS in that. the roll is fine the way it is, of oyu didn't get cards in the 2nd or 3rd pick that was your bad luck.
I only do a 2nd flip if there at least 3 heroes that I want on the 5 cards. The only time I do a 3rd click is under the same situation and the 2nd click did not give me one of the three I want, since I am assured to get one of them.
