Havent played in awhile...suggest some champs

Hey guys, havent played in awhile. Played a couple matches last night with Volibear still pretty decent with him i really enjoy playing volibear.

Heres what I'm asking: I will stay a very casual player putting in a few games maybe every few weeks so i dont want to put in the time to really get too advanced with a champion but i love being able to get on and put up a competitive match in unranked with Volibear. Problem is i cant always have top lane, im wondering what a casual champion that i can pick up and use and mainly is fun here and there and enjoy the game like i do with voli when i dont get to use Voli.

What are your recommendations?
