New Kyrexia

I've been trying to make Coach Driver work since she came out, and this is the closest I've yet come to being able to do so with any consistency.
I originally had a bit more removal, but I swapped out for Rhysta, because I was losing to my own power more than enemy threats. Not sure if that's the right move, but I'm not sure what else to cut, since everything plays a role.

Considering cutting Felrauk's Choice. It's served me well a few times, but just been market fodder more times than that. Not sure if I want Vara's Favor for early sigil draw or Re-Read for being able to pull some removal or recursion back out of the void later.
