Kraven the Hunter

When Kraven the Hunter enters the battlefield,
you may have it fight target non-Human creature
you don't control.
When a non-Human creature less than Kraven's
power and toughness enters the battlefield under
an opponent's control, you may have Kraven the Hunter fight that creature.
Whenever an opponent's non-Human creature
dies, put a +1/+1 counter on Kraven.
