Teemo guide? (Other then uninstalling and Benediction?)

Teemo.

(Hesitance and nervous shifting.)

Am I safe? Well, okay then. Hey there, Master Fledgling here!

I am testing Teemo out right now (Bought him awhile ago, was told never to play him by my Priest and Friends) but I am desperate and will deal with all that later. Namely, I love that he can ward everything, which is a God send for Solo Queue -- lets me take other trinkets, not have to constantly buy wards and not have to buy a sightstone. That alone is wurf.

Additionally, he can carry if you're good. Another check mark for solo queue. I tried him Jungle and didn't exactly carry since it was my first time, but I definitely contributed in a major way to our win -- blinding people, warded everything, got decent farm, split push, etc, etc.

As to not ramble, let me get to it: What are some key tactics for playing as Teemo? As I understand he can sorta play ... everything. I somewhat know how to play him as Jungle now, but what of other positions? How do I deal with the inevitable Teemo taunt?'

Thanks very much and ward your wards,
