The Gromble

When you cast this spell, 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.
The Gromble's power and toughness are each equal
to the number of creature cards in your graveyard.
