Hazell, Blinded Bog Witch

Whenever a spell an opponent controls targets a nonland permanent you control, you may
reveal cards from the top of your library until
you reveal a Curse card. Put that card on to the battlefield attached to that player and the rest
on the bottom of your library in a random order.
When Grunda dies, each opponent sacrifices a permanent equal to the number of curses
attached to them.
