Cosmetic but the details are significant.
I really liked the "when you use sorcery to X, roll+y instead of +x."
It's implicit in the Brainer move that you're using your mind powers and not just being quirky and thus lovable. As such, if as a Brainer, you didn't want to use you mind powers on some one, like you wanted them to actually find you attractive, you'd still have to roll+hot and not +weird. I feel like that detail in other alt+stat moves is missed. That is to say that the stats aren't equivalent fictionally - what stat you use with for move is important and, in a way, generates an alternative move.
