Fonah, Wish Daughter

Whenever an opponent casts a spell, you may reveal the top card of your library. If it has the same converted mana cost, you may exile it.
You may cast cards exiled by Fonah, Wish Daughter without paying their mana costs as though they were instants as long as Fonah, Wish Daughter is on the battlefield or in your graveyard.
"If you can have one thing, I certainly can as well.".
