Geier Reach Hag

{b}{t}: Target player discards a card. If they
discard a creature card, create a 2/2 black
zombie creature token. If they discard a
non-creature non-land card, surveil 2.
If they discard a land card, you gain 2 life.
(Activate this ability only any time you can cast a
sorcery.)
Their concoctions are always free, but the price is still
too steep.
