Death's Foresight

Foresight 2 (You may reveal this card from your library at the start of a game. Exile it. Shuffle your library. You may cast it from exile for 2 more mana used to cast it.)
Destroy target creature. Its controller draws cards equal to its power, loses life equal to its toughness, and gains X life, where X is the creature's converted mana cost.
What death's augur reads is bones.
