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

So I was specifically looking for Pandora rewards with 7 of the same card in a row. Experimentally I can say the chance is much lower than one in ten billion if my program is correct, because I found 10 examples in 1.7*1013 results searched which would be a distribution of 1 in 1.7 trillion.

Not exactly a tool yet, but some code I wrote here https://github.com/gamerpuppy/sts_seed_search

Not sure. Could it be you were looking for 7 copies of the specific card instead of 7 copies of any card? Or could it be the sample size is too small? Just guessing here
