First time doing this so.... anyways

For those who think Teemo is only good for stayin in background and dealing dammage... ur wrong :)
Temmo is a really good tank and Ive played many games as it and got pretty good stats.

The most important thing to do if youre playing with this built is to get the bonus hp and dammage fast. Extra HP from Warmogs and dammage from Bloodthirsters are always recommended...

While having much HP (around 4,5k at lvl 18) you will be surviving much much longer and dont have to be afraid to be the target in teamfights and run away. When they are trying to lower your hp you get a great amount back thx to the lifesteal and your good HP reg. Besides that you can survive much longer you deal also very good dammage + Toxic shot skill + madreds which give you atk spd and more dammage to the enemy!!

Hint: when you are in teamfights dont forget to make use of your mushrooms! 4 example if a melee (like xin) keeps attacking you put a mushroom on him and you'll see he will be happy and slow :D whenever you have a chance to put a mushroom Do It and place it wisely ;)

The negative thing with this built is that you need much gold so you should always do some jungel while going back from lanes or from fights for extra cash.

Btw Guardian angel can be usefull also if you want to make them go mad...

That´s all folks
comment if u have any questions about this built and ill answer as soon as i can.
