Pay 1 to give Crypt Ghouls necromancy. Play them for 2. Sacrifice them to something. Gain 2 resources. Buy them again. Rinse and repeat.
As you can give Necromancy to a card in your the graveyard, cards in graveyards must be able to have abilities granted to them as a power they keep for the turn, or are there any rules on cards forgetting abilities like this when they are returned from play/destroyed again?
