Ojutai Control

I have been trying to come up with a deck based on Dragonlord Ojutai lockdown preventing the opponent from using resources and then swinging with a buff as hell Ojutai. This is the current list that I have. What I would like to do is maybe lower the average CMC a little, try to improve speed, consistency, and make the deck more oppressive if possible.

Any ideas or suggestions are greatly appreciated!
