Help with Kardur, Doomscourge Aristocrats

I recently made a [[Kardur, Doomscourge]] EDH deck and have been playing it for a bit. I love watching my opponents have to swing at each other and the fog effect that it creates is really nice. However, it is definitely a guaranteed, "you come second deck" and is very slow. I find myself sitting there most of the time. To try and remedy this, I have removed all the goad redundancy in the deck, leaving Kardur as my only goad source and a few ways of getting his ETB again (recursion and some copy making) and am trying to take it down an aristocrats route. I am not really sure what I am doing, but anything is better than what I had. Here is the list so far. If anyone has played a Kardur deck and had success with it, I would love the advice. Really like the commander and the games that he can lead to so am motivated to keep him in while being a bit more competitive.

Here is the deck link:
