You can mean different things with "duelist", it seems most people below are talking about 1 vs 1 lane abilities, I guess the topic starter means actually 1 vs 1 combat to the death, while you are still allowed to be smart.

I guess the definition of assassin is that you should be able to kill anyone really fast in a 1 on 1, but bruisers can be high on the list for this as well. I would put LeBlanc, Kassadin, Riven and Jax on the top of my list, they have high mobility and insane damage. The first 3 require something else than glueing yourself to your target, like Jax would do, but they can hit-and-run and repeat like no others. I don't know all champions so well, I guess that Talon, Fiora, Malzahar, Yi and Akali are also very strong in 1 vs 1, but I don't play them myself.

I would say that many mages are actually not great duelists, because they lack utility. For example, Ziggs is a very good mage (that win rate...), but he is smashed to pieces by many opponents in 1 vs 1. Of course he can run to avoid death, but winning a 1-to-1, no.
