This is guide for Teemo the swift scout.... with this build its highly recommended to try and win as fast as u can... because u if u play it rightly u will be very strong early game... after some 30-35 minutes u mushrooms will be your main ability.. and in first 30 min u can kill with darts as much as u like :)

pros;
very fun champion to play....
very anoying for enemy team.....
fast and can escape really easy.....
blinding dart is kiler for dps and can lead to very interesting situations and can help your teammates easily...

cons:
can be targeted oftenly in most games...
low hp... so depends much on W spell...

i take these runes because u need magic penetration and early magic regeneration so u can throw dart as much a u like and place mushrooms... ability power is ok... but u can also take cooldown reduction... this most be in combination with golem buff... u need to take that buff early game so u can put as much shrooms as u can... but it is nesesary that in nearly 90% part of the game u have more than 30% cooldown reduction... it is key for map control.. helping you team mates escape sticky situations etc....

masteries are usual... u can change between more xp or more mana as u like it... its depending on what game i like.... not that big of a deal.... magic penetration is of course nesesary...

i like to take these summoner spells.... teleport because u can teleport to mushroooms all across the map and flash in combinaton with your W ability can be very effective... u can maybe go with exaust or something but i recommend these....

u can farm really well with teemo.... u sometimes can put mushrooms on lane so u can stop minion waves reaching your tower and with that get more minion kills...

for skill sequence i can tell u that u between darts and poison u can go and build what u love more (early game).. but i recomend highly to take 1 W spell at level 5 so u can use it for escaping, ganking and other....
also try to use your passice for same thing.. escaping and ganking... it really fun.. :)

items bulid of course mostly depends on what team composition is on enemy team.... but i think u can almost always go with this build.... malady is very important early game item... because early game everybody have low magic resistance u can really harm them with maladi and your autoatack and Q spell... u take nashor tooth because of cooldown reduction... and attack speed is helpfull.. so low health heros will get severaly damged hear you....
when u have enough ability u take lich bane and in 2,3 sec u can kill their dps champions... using Q to start... of give tham sec to think thay can kill u than Q and they will get really pissed.... u can do this while running away with low hp... u use Q and can take save trip home or turn around and try to finish champion chasing you.....

key ability of course is your ultimate MUSHROOMS.. and its critical that u place tham correctly.. in some locations where enemies go often.... like buffs or dragons or nashor.... or like path crossings, in river etc... you need to watch closely where battles are going down mostly and put shrooms there... and try to put in your enemies jungle so thay know u are watching them and that they cant go anywhere so you than can have map control....


so this is it... i will maybe try to improve this in future.... sorry for my english if u see something incorrect.... :)

P.S. u will have more ability that its stated at start because its not calculated 30% form rabadon and 4% from arhangel staff...
