Mikael Mikaelson, Hunter

Intimidate

Whenever a Vampire deals damage to you,
destroy it.

Other non-Vampire creatures you control
get +1/+1 and have undying. (When a creature
with undying dies, if it had no +1/+1 counter on
it, return it to the battlefield under it's owners
control with a +1/+1 counter on it.)
