The Deuce is the most important card in this game. Do not discard the Deuce if you get dealt with one in the first round. If you have four deuces, discard the other irrelevant card. Hold all of your five cards if you have a wild Royal flush or five of a kind (so the irrelevant cards are a pair) otherwise discard them. Read more: https://bspin.io/blog/deuces-wild/
