Herus, Geistpreacher

Whenever a creature enters the battlefield from a graveyard under your control, you may pay 2 live and remove a +1/+1 counter from it, if you do, create a 1/1 white spirit creature token with flying.
Undying (When this creature 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.)
One lifetime in service of light, wasn't enough.
