Suphlatus, Angel of Dust

Deathtouch, Flying, Trample
Whenever Suphlatus enters the battlefield or attacks, you may destroy target creature or land. If you do, that card's controller may search his or her library for a basic land card and put it onto the battlefield tapped, then shuffle his or her library.
Flesh to ash, bones to dust The heavens rain dry Fill thy heart with scorn, o genius of dust
