Xerxian Cleric

{1}{r/w}: Sacrifice an artifact. Xerxian cleric gains +2/+2 until end of turn.
{2}{r}, {t}: Sacrifice a mountain. Search your library for an artifact, then put it into your hand. Shuffle your library.
Though Xerxes is lost, many clerics of Xerxissinium still remain, watching over the desert and aiding their people wherever they can.
