Cory, Trash Master

You may look at the top card of your library at any time. You may cast spells from the top of your library with mana value less than or equal to the number of card types among cards in your graveyard. Whenever Cory attacks you may discard a card. If you do, create a 2/2 green and black Trash Zombie creature token. {/color#ffffff}{/fontsize-13}
