Tips for playing Teemo?

Don't.

I'm serious. He's really bad in this meta. They've got a lot of changes coming to him as well, so I'd wait to see how those work for him. All in all, Teemo's struggling, and doesn't bring too much to a team other than some objective control.

IF you're going to play him - CDR and shrooms. If you're not shrooming up objectives, you're basically a weak ADC that happens to do magic damage.

Jg teemo isnt the most viable pick, as he cannot really clear anything, and I wouldn't recommend it. However, if you really want to jg, I think Teemo could potentially invade the ennmy jg for kills, so offensive vision would become your win condition.

As you are quite immobile and do not pack meaningfull cc, watchin the map, as a laner, is crucial. Stay at max range and poke them out slowly. He has multiple build paths and I believe the most viable is the Liandre's Torment and maybe gunblade. Also, mute the ennmy team because they will probably flame you.
