Gilad Pellaeo

When Gilad Pellaeo 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.)
