Of course I'm good at magic, [ Strange can't help but respond as if it's one of the most obvious things ever. ] I'm one of the best magicians in the carnival.

[ Except for the Ringmaster. And possibly Sans. And maybe Zecora but Strange is fairly certain he's got her beat on combat magic. But, back to the topic at hand and not Strange being a prideful jerk. ]

We'd want to be as specific as possible. Considering how all of us have been touched by fae magic at some point, I wonder if the spell would count us as changelings.
