Which support should I learn next?

I am on a quest to get level 5 mastery with all supports. I have done all the other traditional supports (plus Malz, MF and Nautalis in thier original positions)

All that remain are the Hooks and Taric. I have also added Brand, who is pretty common as a support these days ,and the new champion, Rakan, which I am not getting until next week to the Poll.

Other is for other Mage supports (e.g ) and other non traditional supports e.g ( )
