Grey Warden Veteran

First Strike, Menace, Taint 3(this creature enters the battlefield with 3 taint counters on it. Put a taint counter
on it at the start of your upkeep. When there are 5 taint counters on this creature, sacrifice it).
Grey Warden Veteran gets +1/+0 for each taint counter on it.
I hear the song clearly now. My calling is soon.
