Maelstrom Wanderer (Foil Etched) (CMR-526) - Commander Legends Etched Foil

Creatures you control have haste.
Cascade, cascade (When you cast this spell, 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.)
