Iris, Fist of Passion

Iris, Fist of Passion's power is equal to the total
number of instants and sorceries in your
graveyard.
Whenever Iris, Fist of Passion attacks, choose an instant or sorcery from your graveyard. You may
cast that spell without paying its mana cost, then
exile it.
She embodies all that is the Jeskai, several emotions balanced into one being.
