In a draft game i cast [[Miasmic Mist]] for it's Mayhem cost. After it resolved my enemies 3/2 became a 1/0, but remained on the field. Both me and my opponent could hover over the card. It did not block so it's probably just visual. Maybe there is some kind of trigger missing with mayhem that usually removes creatures with 0 toughness after a spell is cast?
