I'm currently unable to decide on a champion to buy next. I was hoping someone could help me make up my mind.
I'm looking at: 
I really want a challenge.
If this helps I'm best with:
Top-Shen, Fiora, Nasus
Jungle-Vi, Nidalee
Mid-Lux, Azir, Orianna
Adc-Sivir,Whatever's Free (don't play much adc)
Sup-Thresh, Alistar, Soraka
Save the money. Someday, a video, a gif, or something with make you want to buy a certain champ.
Gnar is very fun, I don't see a lot of people play him, and hes a change in the whole switch when ever you want type of champs, if you're good at the game and can pick up champs (I see you like Azir, if you mastered him, I'm sure you can master Gnar) easily, then Gnar should not be that hard, its fun changing your play style when you turn to your mega form
