intimidate (this creature can't be blocked except by artifact creatures and/or creatures that share a color with it.) whenever a human deals damage to you, destroy it. other non-human creatures you control get +1/+1 and have undying. (when a creature with undying dies, if it had no +1/+1 counters on it, return it to the battlefield under its owner's control with a +1/+1 counter on it.)
