Borbo, Ever-Growing Fury

Whenever Borbo, Ever-Growing Fury attacks,
you may have it deal damage equal to its power
to target creature defending player controls. If a
creature dealt damage this way would die this
turn, exile it instead.
At the beginning of your end step, if a creature
card was exiled this turn, put a +1/+1 counter
on Borbo, Ever-Growing Fury.
