Devoid (This card has no color.)
Eminence — If Kallt, Land Deviant is on the
battlefield or in your command zone, each
waste you control has "{t}: Add {c}{c} to your
mana pool. Spend this mana only to cast an
Eldrazi spell. This land doesn't untap during
your next untap step."
Whenever an opponent sacrifices one or more
permanents, you may draw a card.
