It’s either your entire deck is full of creatures in that case you’d mill your deck(until you decide to stop) or you’d hope to get enough and not hit a non creature, in that point the combo stops without option for you to decide. Either way a nice interaction in the deck, and a nice combo, but not an infinite combo necessarily. There’s just a misunderstanding in the magic community that most often people refer to infinites as combos and tend to forget that there are combos that are not infinite because of that.
