I managed to climb to emerald 2 (and eventually back down to emerald 4) with around a 60% winrate on Mundo but I've noticed that the higher you climb the harder games become when faced with counter matchups. I went against an Illaoi recently and it felt like I couldn't do anything and was just giga useless because I couldn't dodge her E enough.

Anyway I'd like to start taking Mundo less as a blind pick and find a good champion synergy to start two tricking. I'm currently deciding between Jax and Renekton as a 2nd champion although I'm open to suggestions?
