It would be pretty powerful if you were using it alongside a long range physical type, unless the enemy you were facing specifically had a counter for it. Most of the early ones we face don't, so it'd be quite the curb stomp.

I wanna say that as long as everyone else interested is okay with it, that it'd be alright. Definitely wanna come up with a good way to limit it (like line of sight or something) as I'm sure someone else will make a long range physical type you could abuse with it.
