LF P1-D4 ADC main for duo

I've been a support main since season 4 where I peaked at Diamond 2. I completely stopped playing for the most part in S5 and I'm now looking to get back into playing seriously. I've been trying to get out of Plat 2 for what seems like forever now - and I hate to say that I feel as though my losses aren't my fault, but I don't think I'm playing badly enough to lose 14 series in a row. Looking for a moderately relaxed ADC to duo with until I get back into Diamond, thanks.
