Is twisted fate worth maining

I know any champ you enjoy is worth maining, but i also want to stick a lot of time into a champion that is able to be blindpicked, I also play orianna which cant really be countered and has more skill matchups. I hear a lot if mixed things about all champions i'm interested in playing and i start to doubt if ita worth putting time into learning the champ if i hear negative things about them. So im asking for your guys' advice wether or not twisted fate would be nice to add to my champion pool.

Currently my champion pool consists of:

-Orianna -Yone -TF?

If anyone has a suggestion of who i could add i would love to hear it as i play a bunch of mages and i just cant seem to choose a few to play a lot.
