Thanks for your help. I miss clicked on my quints, and changed my runes/ masteries

I'll toss in my 2 cents for you.

First, I'd like to see a little more of a description. Add some more words to it, talk about the pros / cons, etc.

Runes:
Red- Armor Pen is still better than straight AD
Yellow- Attack Speed is decent, but I prefer some dodge runes for Teemo since he's quite squishy and could use some defense ( Move 9 pts from Utility to Defensive for points in Nimbleness to maximize this, and start dodging like a champ)
Blue-Mp5 is next to useless for AD Teemo. Your shrooms will be placed often, but your main source of damage imo is your auto attacks, and your shrooms/blinds will do no damage as AD so the shroom placing and blinds will just waste for mana and precious DPS time.
Quints- Why grab Armor? Anything BUT armor. Armor Pen or Health Quints please.

Masteries-
Offensive:

If you're going to play AD, drop the points in AP, Burning Embers, Offensive Mastery, and put points into Armor Penetration and Lethality You'll need it as AD.

Utility:

If you don't drop these points in Utility, I'd suggest dropping the point in Greed. The 1g/10s is not very good at all. It'd be better put into an extra 15% time in your runes.

Grabbing boots early game already puts Teemo at an disadvantage. Grab a Doran's Blade. Great laning power, and will make your harrassing shots even deadlier. Also, when you grab your Zeal, that is when team fights and ganks will start to begin. You will have nothing but AS and Crit, which will end up being useless due to the fact that you have no AD. Even though Malady is AP now, it's still great for all Teemo's.

Cmon guys, only 1 comment? Plz give feed back and I will make the guide better. Oh and I edited the items/ runes to have a better chance.

This honestly doesn't have the damage output early game to be strong, and your scaling runes don't help that at all. Rushing a Frozen Mallet makes your damage pitiful early game, while Stark's Fervor takes another while to build without providing as much early-game benefit as an early Malady.
