Rowan, the Ravenspeaker

At the beginning of each combat step create
a 1/1 Legendary Bird Creature token named
"Rodrugo" with deathtouch, flying and
protection from from white and from black.
At the beginning of your upkeep, if you don't
control a creature named Rodrugo, each creature
your opponents control gets -2/-2 and
each opponent discards a card at random.
