I've been expirementing with a deck with bonewalls, shards of gratitude, mummies, and rewinds, along with a few gravity pillars, but I can't settle on a final build. When it works, boy does it ever work! Scarabs eliminate enemy creatures and build up your bone wall, and against immortal ones you can eat your own scarabs, and with 3 mummies out and 3-4 gravity pillars, you can stop all damage while still increasing your bone wall! ^_^
