As interesting as tier lists and new character news can be, here’s something you can actually use to get better. Colbycheeze has made a guide for number-one baller Captain Teemo. A good, in-depth video on one of League of Legends more iconic characters.
This guide covers AD/AS Teemo, something I find interesting after running in to only AP recently.
A good review of each of his skills, with of course a few lessons on mushroom placement. Goes over a more tank-like build with 14/16/0 masteries and mostly flat armor, magic resist, and attack speed runes.
Oh, and this.
