I'm still a bit confused on how would that work exactly, given that I don't have a deep knowledge on how does shuffle-based games work technically.
It's really just a problem with *bad* shuffles. After you shuffle an "initial deck" of cards, a good shuffle will give you a possible 52! arrangements (or as close to it as possible). 52! is a mind boggling big number ( 80658175170943878571660636856403766975289505440883277824000000000000 ) but if you're using a shitty shuffle, there will only be 4294967296 possible results, which small enough you can feasibly try them all and see if the initial shuffle is good, bad, great or terrible.
