Causing delays. It will be quick to count the ballots in rural, likely repubs, areas. It will take much longer in urban areas that are likely voting democratic. Eventually they will get a judge to rule that counting has to stop and that the current count will stand, too bad they only counted the rural areas completely.
I think you’re approach is generally correct, but you’ve made a few errors which make it hard to follow (e.g. mixing up suit and denomination).
However, method two is only more efficient if onky a few cards will be drawn. If nearly the entire deck is drawn or dealt, then 1 is superior. Method 1 can be done with two lists and a random number generator. The length of the 2 lists will always sum to 52 and the RNG is used to decide the order that cards are removed from the first list and added to the 2nd. It requires generating at most 51 random numbers.
