+Geistcatcher (2)
When Geistcatcher's Rig enters, you may have it deal 4 damage to target creature with flying.
Whenever you sacrifice another creature, exile it. If that creature was a token, put a +1/+1 counter on Prowling Geistcatcher.
When Prowling Geistcatcher leaves the battlefield, return each card exiled with it to the battlefield under your control.
