Rhune of the Arkblade

Other creatures you control have persist. (When
that 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.)
Whenever a non-token creature you control dies,
if it had a -1/-1 counter on it, create a token
that's a copy of that creature except it's a Spirit
in addition to its other types and it has base
power and toughness 1/1.
