Vilgax, Conqueror

Whenever Vilgax, Conqueror becomes blocked
by a creature with lesser power, destroy that
creature, then draw a card and put a +1/+1
counter on Vilgax, Conquerer. If that creature
is destroyed this way, Vilgax gains all that
creature's abilities until your next turn.

"Ben 10 , I've come to kill you and conquer your world. Is now a bad time?"
