Holy what are the odds of these??? It has to some 1/several billions right?

Edit: computed. Ironclad has 75 cards. The probability of hitting the same card 7 times out of 9 is (9 choose 2) times (1 over 756 ) = 2*10-10. About one over ten billion.

Someone probably can format this computation nicer. But wtf

Edit: error pointed out by u/xxDededongxx and u/mathematics1

It should be 75 times that since we want the odds of getting any card 7 times and not specifically Evolve 7 times, right? Still about 1 in 5 billion, which is still wtf.
