Undying Evil

Target creature gains undying until end of
turn. (When it 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.)
"When you've hovered between life and death
so many times that it doesn't faze you, you may
be called a ninja."— Zabuza Momochi
