Winds of Change

Activate this card only on the stack.
Search your library for as many cards with the same name as the card this card stacked on top of, and exile them. During your Draw Step, you may shuffle one card exiled by this card into its
owner's library. If you do, search your library for
a card with the same CMC, and different name. Cast the card without paying its mana cost.
