Orus, Vizier of the Last Rites

Creatures and enchantments in your graveyard
have Embalm X, where X is equal to their mana
cost. If an enchantment is embalmed, it becomes
a creature with power and toughness equal to it's converted mana cost.
Whenever you activate an embalm ability, you
may look at the top three cards of your library.
Put any number of them into the graveyard and
the rest on top of your library.
