Azog, Moria's Ruin (Showcase)

When Azog enters, destroy up to one other target creature. Its controller amasses Goblins X, where X is that creature's power. If you controlled that creature, draw a card. (To amass Goblins X, that player puts X +1/+1 counters on an Army they control. It's also a Goblin. If they don't control an Army, they create a 0/0 black Goblin Army creature token first.)
