Flying, intimidate, trample (A creature with intimidate can't be blocked except by artifact creatures and/or creatures that share a color with
it.)
Whenever a player loses the game, put thirteen
+1/+1 counters on Orthax, the Vengeful Shadow.
Did I even want revenge before I talked to you?
Did I? I don't remember anymore.
