Cards like Seedborn Muse, Paradox Engine, Quest for Renewal, or Awakening can untap all your creatures at once, and Throne of the God-Pharaoh can sting your opponents for each tapped creature you control, which can help you get in a lot of extra damage. I would run all 4 copies of Combat Celebrant, since it untaps all your creatures, and you can choose not to exert them during the second combat. It can basically let you exert, and then attack regularly without exerting. Glorybringer is an exertable creature that provides you with some creature removal, as well as having flying. Also it feels like a no-brainer to replace Shock with Lightning Bolt. I like this deck, hope you have fun with it!
