Your Elo rank is really low for as great as your KD and win percentage is, that means your not playing many of the top tier opponents. Some of the guys I have played with a lot recently , sUpRock, Oo Cartoons, sD Rocky are all top 25. I've seen them get together and play 9-0 cards and play other top people which raises your Elo skill ranking on guardian gg, maybe you should do that and see how you do against really good people?
