Outsider Sages

Terrigenesis (Whenever a +1/+1 counter is placed on this creature, you may exile it. If you
do, at the beginning of your next end step, return
it to the battlefield under your control with an additional +1/+1 counter on it.)
At the beginning of your upkeep, if Outsider Sages has 5 or more +1/+1 counters on, it
gains vigilance and lifelink.
