This just a very basic guide/build on how to use an attack damage teemo this is my second Build The best score i have got with it is 42/1/38 and my average is normally around 22-Up so it has been very good to me and hopefully you should do good too

In early game you must buy Vampric Scepter no matter what its always a good start to the game you can get that or dorans blade but either one is good. If your opponents are ******s save up a bit to get B.F.Sword then you should be on a streak.But if you opponents are aggressive get berserker greaves if you have a good support like blitzcrank or karma it would properly be smooth riding for most of the game just make sure your not to aggressive or you are most likey to die.

in the middle of them game you should have a couple of kills by now and have your phantom dancer just always try to kill trash and just make sure you leave mushrooms everywhere for map advantage extremely good for ganking. If possible there is a certain lane they are ganking try make one jungle lane a land mine and weave them through it which will slow them if they have lost enough health go for the kill another thing if you versing people like twitch evelyn shaco etc. who can ever go invisible get sight pot then make sure ur with some some so they can also see them it last till you die so it should be good doest cost much only 400g

by this time of the game you should have your infinity edge and be doing big group fights and hard pushes at this point of the game you can never ever go alone cause they will focus on you and get a quick kill so always be with someone no matter what if you they have just about entered your base just normally sty near tower and hit damage on them if they attack back and you have nearly any health and you have downed a fare bit of theres just run on the opposite direction of the tower and hit occasionally if you dont think you can do it hit move quick and it will give u an extra boost hopefully making it in time to survive and heal up.
