Mid main LF serious duo/team

Hey guys, title pretty much says it all. I am currently S1 and would like to find a serious duo that could climb back to platinum with. I'd love to find a serious team as well but I know with my current rating I'd probably not find what I'm searching for. I have solid game knowledge from being on many ranked 5's teams and doing online tournaments. I am searching for non-toxic attitude players who can stay positive and push to be the best. If interested please add Wita Devildriver or leave a comment :)
