Barbaric Aura

At the beginning of your upkeep equipped
creature fights each creature target opponent
controls. Whenever a creature is killed this
way, put a +1/+1 counter on the enchanted
creature until the end of the turn and all damage
marked on the enchanted creature is removed.
Any damage removed this way is instead dealt to
it's controller.
