Garbage Elemental [UST-82d]

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 Garbage Elemental enters the battlefield, roll a six-sided die. Garbage Elemental deals damage equal to the result to target opponent or planeswalker.
