Card Rulings

5/1/2007 If all damage that would be dealt to a creature is prevented, no damage is actually dealt and that creature can’t be targeted by Witch’s Mist.
5/1/2007 If a creature is lethally damaged and regenerates, all damage is removed from that creature. But since it was actually dealt damage earlier in the turn, it can be targeted by Witch’s Mist.
