Yun, the Returned

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.)
If Yun, the Returned is targeted by a spell, you
may exile a creature card from your graveyard.
If you do, Yun, the Returned gains Shroud until
your next upkeep.
"Justice, Kyoshi, [...] I want justice. Everyone who
lied to me is going to suffer the consequences." -Yun
