No shoes until . . . . late game?

Enemy: 'Hey look guys, a Teemo with no shoes. I'll just hit him once, and he'll be slow as a turtle without his passive. Even Rammus roll faster.'

Ive seen someone using this build on dominion, sort off. And with that I also mean the boots really late. We were losing because of him, and when he did got his boots it went way better. We still lost because of it though. Please dont tell me you are the same Teemo...

you should get boots earlier

As stated above, your masteries are not possible. You don't have points in Sorcery. The points in Butcher and Demolitionist are also a little bit wasted, and you ought to switch them for something (almost anything) else.

Your item build is a little odd, especially your last item, since it doesn't give an on-hit that'll be relevant that late in the game; not to mention that you don't need the crit, since you don't have an Infinity Edge, and the life steal isn't relevant on an AP-heavy build. You might also consider taking your boots sooner, since you aren't putting many points in Move Quick until the late game. The build also leaves you extremely squishy (no bonus HP), which makes it a lot more likely that the enemy team is going to focus you dead inside of two seconds, a good portion of which you're likely to spend stunned, suppressed, or otherwise CC'd, lowering your damage output to roughly zero regardless of your DPS.

You've got a lot of armor in your runes, which is a little odd, since you don't talk about it much in the guide, other than a nod to how squishy Teemo is. You also split your quints, which is extremely odd, since 1.89 m pen is almost nothing. You're best off sticking to one or the other, and considering switching most of them to something else (perhaps attack speed?) to boost early game damage.

Finally, your guide has no explanation of how to lane as Teemo, how to use Teemo in teamfights, or even which areas to concentrate on placing your shrooms in (I understand that the long section of images is supposed to do this, but it doesn't show priority).

All in all, I doubt that your build would be useful against intelligent and competent opponents, and your guide is not terribly useful to show new players how to play Teemo. -1.

and your masteries don't make sense
=impossible to achieve

you use to much a instead of u, for example brash=brush, anderstand=understand...

this is not a bad build. HOWEVER it is not good either and i am not saying because i dont like your items/runes masteries. I ve tried it and it was not as a good game as the ones i would do with teemo.

WHat i recommend is: 1)Get executioners calling and divine sword out and replace them with frozen mallet and banishees veil.that way you will have more health and you can do the next thing on my recommendation list wich is...
2)Replace heal with flash health sucks after mid game phase and with flash you can turn the tables to your opponent
3)Runes should be in my opinion armor penetration but if armor is good for you ... no problem
4)If you follow step for then you should make your masteries 21-9-0 with emphasis on armor/magic resistance as regards defense

to help with the English in "Prons and cones of Teemo" should be Pros and Cons of Teemo
and in why Heal should be use awey should be away same with heal and in the section "Enemy team has Orcale :/ What should i do" brash should be brush... i like the build though and im just trying to help spelling errors :)
