the basis of this build is to hit em hard and fast early on with you poison to prevent them from feeding its not so good mid game so make sure you stay behind your supports and let them take the damage but late game the combination of your attack speed the damage from your ionic spark and the critical strikes you can do teemo is almost UN-stoppable
I added in the AP build because the people deserve to have a choice one how they play teemo and i have tried it before and both AD and AP teemo are pretty boss against almost any champ

you want to get your poison up first so combine with your increased attack speed you can spam the **** out of your enemy and by the time they get to their tower the poison will finish them off
the second skill you want to max out is your ult
the third and forth skill you want to max out is your move quickly and your blind so you can escape and help your allies escape
How to abuse teemos skills
one you reach lvl 6 with teemo you want to use your mushrooms to make a wall straight across the river so you cannot get ganked without u knowing spam your mushrooms in walls around your turret but don't bunch them up too much cause that damage does not stack so it would just be a waste of time, put the mushrooms in the bushes, put them across entry ways of your jungle to help out your jungler for invaders and be sure to pay close attention to your mini map.
when fighting an enemy use your blind first and then commence your attack for most champs that depend on their basic attack this will shut them down long enough to get the advantage, your blind however does not stop an enemies skills from hitting you.
when running away pop both your move quickly not your ghost and save your ghost for an enemy that has high movement speed and as your running throw down some mushrooms to also slow them down but if you find yourself being chase by a master yi with his ult popped quickly turn around hit him with your blind and keep running this will make all his attacks miss while he is blinded
late game if your team is loosing or winning you want to abuse teemos passive if you stand still for 5 seconds teemo turns invisible so if you got your attack speed up mid to late game if the enemy team is all pushing one lane hard and our minions are pushed in one land go over and take the turret with teemos attack speed you should be hitting rapid 100's on the tower and a full health turret should be dead in 10 - 15 seconds then go to the side of the lane and go invisible and wait for them to thin k you have left
if its a bad team they usually do not buy oracles but if it is a good team use your ghost and you W or move quickly skill to get away, and if they are still keeping up use your ult and put shrooms right in front of you as you run and that should help even if it doesn't hit them it will give you a little bit of space between you and them if they have to go around
also if your close to a turret an their turret diving you at low health use your Q to blind them 75% of their attacks should miss you
DO NOT stack teemos mushrooms the damage does not stack but if you spread our your shrooms enough it will do consecutive damage plus you shrooms also deal poison damage
i use speed runes only because teemo really doesn't need any other runes even if he did the wouldn't be very helpful, this way he can shut down the bottom lane or whatever lane he is running early game so not only will you get fed off minions but your attack speed should be high enough to kill the enemy before they get a chance to get close to their turret
these items all have a purpose
-murcurys treads are helpful early on to help you get away from and chase down your enemies plus it gives you a lil magic resist so that's helpful
-malady gives you a lil boost in your AP early game plus boosts your attack speed even more
-ionic spark gives you a bonus 50% attack speed plus every 4 shots it deals an extra 110 magic damage and at the end of this build you should have at least 2.2 attack speed so it will be very effective late game
-the phantom dance is to finish getting your attack speed and to help your infinity edge so your crit more often
-with all this attack speed and a blood thirster teemo will be a very hard little munchkin to kill
-like the other build you start off with the beserkers graves for your attack speed cause ap may increase your poisons damage over time but it doesn't mean anything if you cannot finish him
-the malady and nashor's tooth give teemo a little ability power and attack speed off the back
-the hextech gunblade gives teemo the life steal he needs to sustain himself in team fights plus his unique active
the rabadons death cap is essential to any ap build cause it grants +140 AP and also gives +30% of your current ability power
-and the scepter gives teemo even more AP and its passive slows enemies
-ghost you can us both offensively and defensively and late game if your are trying to get away with ghost and they have ghost too combine it with your move quickly skill and no one can catch you
-ignite is for those low health little ******* who hide behind their towers so u can run in combine your ignite with one shot of poison and their dead
when farming minions stay behind your support this build does make teemo pretty boss but he is still one of the squishiest champs i know
Pros / Cons
-pro: teemo is one scary little munchkin if he is built and played right and he can pretty much solo almost any champ
-con: he is one of the squishiest champs in the game and because he is so powerful people will usually target you first in team fights
stay at the back of your group so they don't try to target you first and in team fights aim for their AP/AD champs first, with this build you should be able to take them out very shortly
use your blind or Q skill to help your team mates escape if they are being chased
lace as many bushes and jungle entryways as you can so if your team needs to escape they just have to run into the jungle
thank you for taking the time to read my build and please leave comments and rate it if you like it

if your do not believe me that this works look up my match history on league with teemo even if my team looses with this build i always get fed
