Grenzo, of Chaotic Miracles

Non-land cards on the bottom of your library
have reverse miracle, where the cost is equal
to the cards mana value. (This includes color.)

Reverse miracle costs are reduced by X, where X
is equal to Grenzo, of Chaotic Miracles' Power.
(Whenever you search your library, if a card with
reverse miracle is on the bottom of your library, you
may cast it for it's reverse miracle cost.)
