Iroacha, Lunar Roar

When you cast Iroacha, search your library for
three cards and shuffle them. Randomly discard
one card face down, exile one card face down,
and keep one card. At any time, you may pay
{w}{u}{r}{g} to switch the cards in exile and in your
graveyard, without looking at them, as long as
a card remains in exile.
{2}{w}{u}{r}{g}, {t}: Shuffle Iroacha into your deck.
"From the thunders of Theros to the droughts of
Mirrodin, all are the doings of Iroacha"
