Eternai Blood

Lifelink, menace
Whenever a creature dealt combat damage by
Eternai this turn dies, put a +1/+1 counter on it.
When Eternai would die, if there are one or
more +1/+1 counters on it, instead exile it, then
return it to the battlefield under its owner's
control at the beginning of the next end step.
