Naktamun

Each creature card in your graveyard has embalm. Its embalm cost is equal to its mana cost. (Exile a creature card from your graveyard and pay its embalm cost: Create a token that's a copy of it, except it's a white Zombie in addition to its other types with no mana cost. Embalm only as a sorcery.) Whenever chaos

ensues, you may discard a card. If you do, draw a card.
