If you had to climb solo Q from Bronze to Challenger with only 1 champion, who would it be?

Only one champion? You'll have to keep in mind you need to pick something that is never ever banned. I'll vote for , rarely banned and you can mid and jungle! :D

Talon. I literally play him anywhere and hes never banned since everyone thinks hes trash.

Irelia

Zed or Lucian

In all honesty there is no way to climb to Challenger without being really good with quite a few champs.

Vayne.

toughone i recomend jinx or lee sin maybe riven

gg.

he's past his nerfs, he will be left alone for some time. He also has a great team fight, and a pretty good 1v1.

I'm really fond of Leblanc. She's a solid champ that can beat any mid laner if you know what you're doing.

probably champions that are like never touched or talked about but aren't non meta

but jax is finally starting to see play again

probably because she's a pretty reliable champion and is always fun and rewarding to play IMO.
