Rabbits and deer always, if you have catnip then neighborhood cats.
Basil will get black spots if it is too wet for too long of a period, so be ready to pick it and make a freezer full of pesto if that starts. Once the stems start turning black, it's on it's last legs.
Japanese beetles love basil, so keep an eye out for them. In our area that's July, if you have already planted, it's probably much earlier.
I like your mix, good choices.
