Unleash (You may have this creature enter the battlefield with a +1/+1 counter on it. It can't block as long as it has a +1/+1 counter on it.)
Creatures that have +1/+1 counters on them have Extort.
(Whenever you cast a spell, you may pay {w/b}. If you do, each opponent loses 1 life and you gain that much life.)
