Disciple of Xavier

When Disciple of Xavier enters the battlefield,
you may search your library for a card, reveal
it and exile it. You lose life equal to that card's
CMC.
When Disciple of Xavier dies, put the
exiled card onto the battlefield under your control.
His insight has allowed me to fetch treasures mortals
could never imagine. Now he frees me from this world
to experience a better one.
