Looking for a supp to help me climb out of bronze.

I am an ADC that mains Sivir, Lucian and Jhin. I am looking for a good supp to play ranked with to help me climb out of bronze. I am very active and a huge TSM fan. I have been playing from mid s6 so i'm not the best but looking for improvement tips. I watch a lot of the LCS so i at least know what i'm doing (most of the time) I am on quite frequently as I very much enjoy playing this game.
