The Mouth of Sauron

When The Mouth of Sauron enters the
battlefield, target player mills three cards.
Then amass Orcs X, where X is the number
of instant and sorcery cards in that
player's graveyard. (Put X +1/+1 counters on an
Army you control. It's also an Orc. If you
don't control an Army, create a 0/0 black
Orc Army creature token first.)
