Rendclaw Trow

Wither: (This deals damage to creatures in the
form of -1/-1 counters.)
Persist (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.)
Demi-Humans are creatures small in stature, but with
a violently brutish disposition. Though they seem
somewhat intelligent, when night falls their blood boils,
and they become feral.
