Maelstrom Wanderer

Mana cost: {5}{G}{U}{R}

Legendary Creature — Elemental

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.)
