Devour the Angels

At the beginning of your upkeep, choose an opponent. If they were to cast an Angel, exile it. Your creatures gain +1+1 for each creature destroyed this way.
"There was talk amongst the Angels about our last raid on the Dark Kingdom territory. They say that the Angels they saved were half eaten. Others say that they were no longer Angels. I saw them myself. I wish to no longer speak of this."
