Beguiling Trespasser

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 of your library in a random order.)
When Beguiling Trespasser enters the battlefield, if you control a creature with submerge, draw a card then discard a card.
