gold 3 promos for gold 2 looking for adc to duo with (supp main)

I'm really good with thresh, but I kind of want to spam soraka, I feel she is strong right now and can secure some easy wins. Trying to climb to plat right now so preferably an adc that has strong mechanics and laning phase, which can be snowballed into strong team fighting and winning games.

My top supports: Thresh, Lulu, Soraka, Braum, Leona, Janna, Bard, Tahm Kench
