Kazanath Vaurein

Eminence — Whenever a Spirit card would be
put into exile, if Kazanath Vaurein is in the
command zone or on the battlefield, you may
pay {w/b}. If you do, put it into its owner's
graveyard instead.
{t}, Sacrifice another creature: Each opponent
loses 1 life. You gain life equal to the life lost this
way. If the sacrificed creature was a Spirit, you
draw a card and you lose 1 life.
