In the case of flushes, the wild card(s) should always be treated as aces. That is why 5 of a kind becomes possible, and is, incidentally, the best hand. Duplicates obviously do not matter, because a wild card is always going to be a duplicate of another 'natural' card in the deck. If you are going to play with wild cards, then you have to accept that wild cards are just that: wild. People often get hung up at home games with the arbitrary notion that a 'natural' hand trumps a 'wild' hand. This is actually my understanding, and the correct interpretation I believe. In my view, if you allow 5-of-a-kind, you have to allow other screwy hands, like:Ģ wilds + 963 spades = flush, AA963 (each wild used as ace of spades), which beats
Two flushes, AK987, say, one natural and one that uses wilds, would split the pot.
Whether a card is 'natural' or 'wild' should have no impact on ranking.
