Wesley- Farm Boy

Legendary creatures you control get +X/+X, where X is the number of Legendary creatures
you control. Whenever you cast a legendary
spell from your hand, exile cards from the top
of your library until you exile a legendary nonland card with lesser manna value. You
may cast that card without paying its mana
cost. Put the rest on the bottom of your library
in a random order. "As you Wish"
