Well, I find it that a good way to avoid such trap into the unrelenting power creep is to establish one or two moves should you begin anew and make it clear that that's what your character will roll with at the beginning. That way, there is no chance to make an unlimited bag of abilities.

Also describe said technique and establish that it does one or perhaps two thing at max so it doesn't become a swiss-knife.
