Saman'thiael, Emissary of Fire

Flying, first strike, menace, ward—Pay 8 life.

Cards in graveyards can’t be the targets of spells or abilities your opponents control.

Whenever Saman'thiael deals combat damage to a player, it deals that much damage to each creature
and planeswalker that player controls. If a permanent would be put into a graveyard this way, exile it instead.
