Mikaeus, the Unhallowed

-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.)
