I'm thinking of who to one trick this season i dont know who to choose Diana or Azir since i used to be a top laner and im thinking of switching to Mid Lane
Go with the champion that you find the most enjoyment in playing. 1-tricking a champion isn't about how good the champ is, it's about how much fun you're having with said champ. If you don't like the champ or don't feel any enjoyment in playing it, your supposedly "1-trick" session is not going to go well.
Just go to a champion you love to play, as a one trick Taric the main thing should be how fun it is to play the champion because you are going to spend your time on him. If you love Azir more go for him if you like Diana more you for her
For Mid Lane, Twisted Fate is probably one of the best champions to both one-trick and to learn more about Mid Lane and the game with because of the more macro-based decisions that he requires over mechanics.
If you strictly want Diana or Azir, then if you don't want to dedicate a lot of time into learning mechanics then you should go with Diana. Otherwise, Azir is a good choice but hard to pick up and stick with.
