Diamond 5 adc lft

I would like to join a diamond ranked 5s team (or at least a team with diamonds in it) I feel as if I hit a skill cap at diamond 5 (at least in terms of climbing) I would like to improve past it. I play meta adcs usually now since you have to in order to win solo q, but I can play champions like Kogmaw vayne to, I play silently normally and don't shot call anything unless no one else on the team does, I have a somewhat aggressive playstyle.
