Death Toll Banshee

Reveal cards from the top of your library until
you reveal X creature cards. Put all creature
cards revealed this way into your graveyard,
then put the rest on the bottom of your library
in a random order. Death Toll Banshee's power
and toughness are each equal to the number of
creature cards in your graveyard.
When Death Toll Banshee dies, put a 2/1
Faithful Hound token onto the battlefield.
