Path of Eternity

Each creature card in your graveyard has reincarnate. The reincarnate cost is equal to its mana cost. (When you cast a creature spell, you may pay the reincarnate cost of one creature card in your graveyard. If you do, exile that card and add its text to the creature spell's.)
For each creature card in your graveyard, replace all instances of that creature's name in its text with "this creature".
