Phea, Caught in Twilight

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.)
If damage would be dealt to a creature you control, prevent 1 of that damage. If Phea
has a -1/-1 counter it, prevent 2 of that
damage instead.
