LF Ranked team, Mid main

I'm a mid main looking for a team with players in Silver-Gold preferably. I main Karthus and currently have a 79% win ratio with him in 30+ games this season. Can also play Annie, Heimer, J4, and a few others in mid lane but will almost always prefer to play Karth. Anyone interested can add me in game (McMorky Bruger) Also, I have skype and can get other forms of communication if necessary. Thank you.
