Wotc can do this, sure… so long as they restrict it to BO1. In BO3, decks needing to run a couple pieces of hate/interaction in the sideboard to deal with a linear combo is good for the health if the game, if anything. (If that’s still not enough, then sure, ban it globally. But BO1 and BO3 are fundementally different games.)

Yeah, post-shaving alopecia is a thing, especially in double coated breeds. (Which is part of the reason you’re supposed to avoid shaving them.)
