Zhulodok, Void Gorger (Display Commander) (Foil Etched) - Thick Stock (779) [Commander Masters] [Etched]

Colorless spells you cast from your hand with mana value 7 or greater have "Cascade, cascade." (When you cast one, exile cards from the top of your library until you exile a nonland card that costs less. You may cast it without paying its mana cost. Put the exiled cards on the bottom in a random order. Then do it again.)
