Amass Goblins 1. If this spell was cast from a graveyard, amass Goblins 3 instead. (To amass Goblins X, put X +1/+1 counters on an Army you control. It's also a Goblin. If you don't control an Army, create a 0/0 black Goblin Army creature token first.)
Flashback (You may cast this card from your graveyard for its flashback cost. Then exile it.)
