Not Updated For Current Season
The masteries shown here are not yet updated for the current season, the guide author needs to set up the new masteries. As such, they will be different than the masteries you see in-game.
This is my idea of an Ap Teemo, It's not perfect and I would like some suggestions on the item list and rune page. I think the skill progression is well balanced because I like having move quick on at all times, and getting that one level before I get my ultimate helps a long way I think. The items themselves have no particular purchase order, I just remembered the perfect ap game I once had with Teemo, and of course added in two more items (I didn't purchase phantom dancer that one game, not enough time) Now as for runes, I went where the items didn't go. I'm not particularly sure that that is a bright idea, but I feel like I'm covering all the bases, and it doesn't feel like hes attacking way to slow. Also with the masteries I usually go offense with Teemo, but if anyone has any good arguments towards Teemo using utility, defense, or even a better combo, feel free to reply.
