Support Looking for ADC duo

I'm a decent Plat 1 support with a wide pool of champions i can play. I'm best with morgana, leona, janna, and braum. I like to go offensive.

I'm looking for a good ADC to duo with that is plat 3 or higher. Last few adc's set the bar really low. I'm not looking for LCS plays I just want to avoid idiots.
