Ravenous Gigamole (BRO-113) - The Brothers' War Foil

When Ravenous Gigamole enters the battlefield, mill three cards. You may put a creature card from among the cards milled this way into your hand. If you don't, put a +1/+1 counter on Ravenous Gigamole. (To mill a card, a player puts the top card of their library into their graveyard.)
