Hi
I'm a bronze player that mains top lane
I would like to expand my champion pool and I'm asking myself if I should buy 
or 
I would like to know who is the best for SoloQ and with which one I could climb easily
Note: I main Camille, Jayce, Gangplank, Fiora and Swain
Thanks
Renekton is probably going to feel the most comfortable, comparing it to the rest of your pool. However, I've noticed what you're really missing is some kind of play-from-behind champion. Someone who weathers lane bullies and ganks well, and can translate solid farming into a later victory. Swain and Camille do this alright, but they're more middle-road.
My recommendation is Nasus, but some others that would work include Tryndamere, Wukong, Heimerdinger (but he's pretty weak right now), Vladimir, Yorick, or Malphite, and Rumble works alright for this, too.
renekton because rumble kind of depends on a team but you can just play split push renekton and you have more kill potential in lane as renekton
Yorick
Renekton has a lot more potential.
Watch SoloRenektonOnly on youtube (his legit builds, not the funny crit builds).
