Pulling off a capture defense with the Emperors is difficult because it's so hard to get initiative. If you want to do Raider's Camp/capture, I'd switch to Syrians. Also, Judges' Seat seems like too many strategies in one deck, but I'd test the deck and see what happens. It very well might work well as a weird standalone card.
If you stick with Emperors, you definitely need Heavy Taxes. I think it's possibly the best EE in the game right now. On an Emperor with Naaman's Chariot and Horses, it discards two cards from their hand and wins the battle unnegatably. I'd cut a few of the captures, specifically the PG and Gold ones, and add some different battlestoppers.
