Whenever Shagrat attacks, attach up to one target Equipment to it. Then amass Orcs X, where X is the number of Equipment attached to Shagrat. (Control of the Equipment doesn t change. To amass Orcs X, 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.)
