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.)
