Help with ranked

So, i decided to start playing ranked. I have 21 champions and i can play 10 myb. I am currently 1-1 in ranked. 1 game i lost cause they aced us when we wanted baron then pushed really hard. So i want to main talon, i have him and his blood moon skin and i am lvl 4 on talon. Should i play talon or another champ? My mains are Warwick, Talon and Ashe. Who would be the best to climb out of bronze. Thanks guys!
