Let's say there was some bizarre glitch in champ select and you have to pick a champ without any knowledge of your teammates champions or even the roles they selected. Who would you choose and why?
Which champion is the best all rounder in your eyes for playing any of the 5 main roles?
Even though I am useless with her I am thinking Kayle could be a contender, although teemo also probably could be a safe shout.
Be pretty much anything but jungle, even if you fall behind your kit makes you a strong enabler for your teammates.
He could literally fit into any comp what so ever and because of his abilities and the way he works he can roll jungle/top/support and he would do good in any of those positions and because he steals stats no matter what the enemy champions were he would always be prepared for anything.
He may not be the best for mid but because of his passive he could survive it easily.
i feel like Jayce's kit has potential
Trundle, Kayle, Gravy, Ez, Teemo, Cho.
Trundle #1 in my opinion.
Ez brings nothing to the Support role, very little to the jungle except damage, and a built in Flash.
Teemo isn't a support, but for the sake of the argument - he has a blind/mushrooms. I've seen Teemo jungle S more of a "thing" right now, and I can't get it through my head as to why, but yeah.
Kayle can theoretically do it all, pretty well too. I'd still pick trundle though. Offers so much.
Cho - for the sake of the comment... Does have a knock up/silence for a support. But his passive is useless for a support as it would not heal him. But other than that he works fine in mid or top.
Graves - I mean I guess he has a smoke screen and could annoy the hell out of you as a support.... But I mean anywhere else he can still do his thing.
Trundle.... #1.
Pretty sure it's Lee sin. He can do anything but be a traditional ADC, and even then he could fill that roll if he has a good match up
Why are people saying Teemo? He's even shit in his preferred lane (Top). He can't operate properly as an AD Carry because he has no steroids, Jungling as him is more trouble than it's worth, Support basically leaves your ADC in a 2v1, and in the Mid lane he gets blown up by anything and everything because his gimmicky range advantage no longer exists in 9 out of 10 matchups and he has nothing in his kit to deal with burst.
I'd personally say Trundle and Nautilus are the most versatile champions in that they can effectively Jungle, Support or Top. Kayle would be a close contender but her effectiveness in Top, Mid and Jungle largely relies on current meta and itemization whereas Trundle and Nautilus have a plethora of Tank/Bruiser/Juggernaut/Physical Damage Offensive items and slot fairly well into most metas. Just like Teemo, Kayle is a gimmicky ADC and an incredibly sub-par Support which basically exists as a lower-tier 'saviour' Support below Zilean, Soraka, Janna, Nami (this list goes on and on before it even gets close to Kayle).
There are jack of all trades for each role.
ADC- 
Mid- 
Top- or 
Jg-
Support-
or 
When i came on here, was about to say teemo. Teemo is god
If you were talking about legitimately all roles? Probably kennen.
-_- support is kinda lack luster but... you've gotta take the rage out from not having a cigar anymore somehow!
J4 can do all roles but ADC to decent success.
Same with Irelia, especially in the case of top/mid/jungle.
Faker proved Olaf is a contender, even if most people are so bad with him that he's considered garbage in most seasons.
The obvious Trundle or Nautilus.
he can play top, mid, supp, adc+jungle (they suck but it can work w right support, Jungle just sucks)
used to be 
, these days the best is probably
