Looking for a commander

I'm looking for a good commander for a new deck I'm planning to build. I want to play more with white+black+blue. I'm want to try and use that color combo to make a new commander deck. I think it'd be cool to have a soldier/knight deck with lots of token action, control and denial spells, as well as graveyard interaction. Please let me know if you have any good commanders in mind that I could build such a deck around. Thank you!
