Heartless and unhallowed

Creature spells you cast cost less to cast. Creatures you control get -1/-1.

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.)

Flying When this creature enters, draw two cards. Evoke (You may cast this spell for its evoke cost. If you do, it's sacrificed when it enters.)
