Rounding Out 10 Regular Champions

In the past I've been guilty of only focusing on limited number of champions/roles and this coming season would like to break out of gold. I have 8 champions I'm comfortable with between all the roles except ADC, which I still just can't force myself to play. I still consider myself a support main, but would like to expand a little bit further and have a solid top 10. Based on my champions below could you recommend me 2 champions to work on to round out my game and handle any counters/etc. especially for jungle/mid.

Support Support Mid Support/Top/Jungle (Main champ) Top/Mid Top/Jungle Top/Jungle Support/Mid

Here's a handful I'm interested in, but feel free to suggest any others. Also, I'd like to avoid common bans.

Thanks!
