Prophet of the Sunset

Lifelink, Ward {2}
Whenever you sacrifice another nontoken
creature, you may pay 2 life. If you do, you may
search your library for a creature card with mana
value equal to 1 plus the sacrificed creature's
mana value, put it onto the battlefield, then
shuffle. This ability triggers only once each turn.
"For every sunset, there is always a brighter sunrise."
