Now obviously this is an impossibility from a realistic standpoint. Every champion in this game has at least one person who "Mains" them. I refuse to believe that it's possible for there to be one who doesn't. Refuuseee-o!
However as time goes by mains change and certain champs fall into and out of favor.
So therein comes to my question... If you had to pick a bunch of champions who you think probably have the least "Mains" currently which ones would they be?
Taliyah has the least mains right now.
Poor yorick
Normally, I'd say newest champions. not possible to main a champion that was released less than a week. Even if you had the chance to try them in PBE.
only the hardest of hardcore nunu players still play nunu, and they only do it with the goal of taking all of the lowest win rate roles on champion.gg in mind. Some day you will achieve your dream, Nunu players...
(I think Urgot players have this goal in mind as well, but I'm not sure.)
Why hasn't anyone brought up 
yet?
His kit is so simple that anyone can pick him up, as long as you know how to land skillshots.
######Totally not luring Amumu mains
and 
Course I base this on never seeing them.
Seems Accurate to me.
Obviously, you sometimes see them get played. But I would say I see these the least BY FAR.
This may not seem so, but statistically speaking, here are the bottom 3 mained champions:
Let me explain my theory on why this is.
Warwick brings quite a bit to the table, but other champions that do the same thing as him do a better job, such as Vi and Nautilus locking down carries, or Xin Zhao and Jax being sustain monsters. He just doesn't distinguish himself enough, which is why Warwick is a rarely mained champion.
Amumu is a weird one, but here's my take: he's a tank with only one niche and a very weak early game. He is powerful, don't get me wrong, but there are also many alternative choices for AoE CC that draw people away from Amumu and towards junglers like Sejuani, Nautilus, and Jarvan.
Shen is another unfortunate case. Pre-rework, he had plenty of mains. Nowadays, mains are far and few, and most of those who proclaim they are Shen mains aren't truly Shen mains. AP Shen is officially dead, and so is Vorpal Blade, which is what drew many people to the ninja in the first place. Thus, he has fallen short of many peoples' expectations, and became a linear tank.
please
Just sounds super weird to main
"Hey who's your main champ?" "Sejuani." "...."
