Female Power

Once per turn, you may sacrifice a male human creature. If you do so, put a +1/+1 counter on
target female human creature.
Whenever a male human creature is sacrificed (excluding the scenario above), put a +1/+1
counter on target female human creature.
"The most powerful of all, is a girl who has no
martial arts background."
