Ardent Plea

Exalted (Whenever a creature you control attacks
alone, that creature gets +1/+1 until end of turn.)
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.)
Just when you're certain that you're alone, help shell
come.
