I noticed Urgot's rework makes him left handed since his right hand is just a big gun. This got me kind of wondering, what other champions are left handed? A Red response is unlikely, but if every hero in Overwatch can love pineapple on pizza, then anything is possible.
Well I think we can all agree Trynamere isn't left handed ( ͡° ͜ʖ ͡°)
There are quite a few ambidextrous champs.
Left handed champs are also in league.
It was stated that Zed is ambidextrous, so he does use his left.
My understanding is that Ezreal is not necessarily left handed. He got a gauntlet, and it's a left handed gauntlet. That doesn't make that arm his primary arm.
I'd say Jhin, since he holds his gun in his left hand.
But then again he also uses his W with his right hand, so it's not really clear.
It would kinda suck for him if Urgot wasn't.
ew pineapple pizza?what blasphemy is this?!
, maybe 
but he probably is ambidextrous
in all skin splash arts
Rageborn 
in some splashes, but it's just a staff so I don't know
unless he's able to use both hands well (I think in some AA animations he switches hands)
Whew, all of them? I will probably miss many of them, but let's see:
99% left handed, for obvious reasons:
Uncertain left handed:
since he uses a shield with his right hand, and while it's his only weapon, it's also an arm shield (and not a grip shield like Goofy from Kingdom Hearts, just to make an example); this essentially means it uses an unnatural position for the dominant arm.
this was tricky, since she uses both of her main weapons with both hand; I went for left handed only because she keeps her gun on the left side, so maybe it's her preferred side.
definitely ambidextrous, but he throws axes with his left hand, and throwing is generally a movement done by the preferred arm, if one can choose.
same as Braum.
Side note: many champions are definitely ambidextrous. However, ambidextrous people still have a preferred side, so they can still be categorized that way.
is a confirmed left handed. It was mention by one of the rioters during her AMA when she was first release.
is left-handed.
Depends, do you consider in game model or splashes? If splashes, do you consider skins?
For example, splash-wise, all Darkin champs are, but in-game, Varus is not.
I think Teemo is left-handed on all his skins except Lil' Devil and Omega Squad, as he's holding the blowgun with his right hand during dance and idle animations - on all the other animations he's holding it with both of his hands (well, neither of his hands to be precise, it awkwardly floats in front of him xD).
ezreal i think
My only real contribution to this is that Xerath is probably ambidextrous, as in his auto-attacking animation, he throws bolts of energy from both hands.
