Looking for a high bronze/low silver adc to support?

Hi, I'm looking for a high bronze/low silver adc to support. My supporting stats are absolutely horrible right now because I started going on a losing streak and being a support main, I couldn't carry myself out. I'm looking for an adc that can win me some games. Also, I cannot skype/voice call when I'm duoing. I play Karma, Thresh, and Blitzcrank as my supports. Thanks!
