But then captain wen’t back and lived his whole life, ending up in the same timeline. I hope i remember it wrong, but that’s bad continuity

No really, more often than not, the same deck is used many times, most homes have a deck or two they use until they can’t, so after a single game, just putting the deck back together would possibly make it novel, then shuffling on top of that. The chance of shuffling a deck which has existed before, is less likely.
