This is how you do it, AD teemo all the way. Blinding shot is not needed because early game it just takes mana and is only effective on certain champions.

Camouflage. If Teemo stands still and takes no action for 2 seconds, he becomes stealthed. After leaving stealth, Teemo gains the Element of Surprise, increasing his attack speed by 40% for 3 seconds.

I really enjoy playing teemo, with his passive. Especially when im Soloing mid. The thing you should do, is buying boots, rush to the mid, get as close as you can, to the enemy tower, just out of range for it to shoot you. And then, when you're stealted and the enemy solo champion is going mid, you should surprise him, by giving him a stealthed shot. Which will increase your attack speed by 40% for 3 seconds, just enough time to take him down :)

Blinding Dart. Obscures an enemy's vision with a powerful venom, dealing damage to the target unit and causing all attacks to miss for the duration. Deals 80-260 (+0.8 per ability power) magic damage and causes the target to miss all of their attacks for 1.5-3.5 seconds.

I really like Blinding Dart, the target will be unable to hit you, for 2 seconds, how cool is that? combined with Exhaust for even better results. Popping Blinding Dart, and then Exhaust right after, will be you best shot, at those hardcore melee Champions, probaly the best combo against them, thats one of the reasons that i took Exhaust as my Summoner Spell.

Move Quick. Teemo scampers around, increasing his movement speed until he is struck by an enemy champion or turret. Toggle: Teemo's movement speed is increased by 15-35% until he is struck by an enemy champion or turret.

This is a very decent abillity, running faster is always nice. However, this is not your no. 1 streaming priority, but it is nice, to get back to your lane fast, if you wanna purchase new items, or if you die But yet not the most important thing in the world.

Toxic Shot. Each of Teemo's attacks will poison the target, dealing damage each second for 4 seconds. Teemo's basic attacks poison their target, dealing 8-35 (+0.14 per ability power) magical damage upon impact and again each second for 4 seconds.

Toxic Shot is a very nice passive ability. Its dealing posion damage over time, which is really good. If you are about to kill an enemy, and he flee with very low HP, the Toxic shot might take care of the rest ;) and the Damage will increase if your building Ability Power.

Noxious Trap. Teemo places a explosive poisonous trap. If an enemy steps on the trap it will release a poisonous cloud, slowing enemies and damaging them over time. Uses a stored mushroom to place a trap which detonates if an enemy steps on it, spreading poison to nearby enemies which slows movement speed by 30/40/50% and deals 250/475/700 (+1 per ability power) magic damage over 4 seconds. Traps last 10 minutes. Teemo forages for a mushroom every 30/26/22 seconds, but he is only big enough to carry 3 at once.

You gotta love those, always get me kills on the battlefields of justice, while doing nothing ;p What you wanna do with your traps is, try to place as many as you can, all around the map, to reveal your enemies.

Early Game Level 1-6
Teemo is very squishy, so you should try to play defensive, the first 4-6 levels, but of course, get a kill if there's a chance for it. You should try to farm, minions as much as you can. Cause when your or the enemy team, starts pushing, you won't get the chance again. Blinding Dart is very usefull Early Game, if you're playing against Non Ability Champions, like Tryndamere. I would recommend taking mid, as Teemo. He can really do a great Damage Output, and use for the most advantages for you. But he also works great at side lanes. Just try to play defensive, and blow a Blinding dart, whenever the chance breaks out. At level 6 you'll get , which is really good for Teemo, especially with an Ability Power Build.

Mid Game Level 6-12
You should probaly, have 1 or 2 items from the builds by now. (Attack Damage - I would try to use, Madred's Bloodrazor to get Lizard and Golem Buffs ) (Attack Speed - Use Stark's Fervor in team battles, Into benefits for your team. ) (Hybrid - Just destroy your enemies with Hextech Gunblade. The best Hybrid item) And Ability Power - Try to get those great stats within this wonderfull Rod of Ages). Use them to its advantage. In level 11 you will get, Rank 2, try to place them at the locations, that i pointed out above in "Trap Information." And try to get as many kills as you can.

Late Game Level 12-18
Iam aware that you might won't get all the Items, since they are expensive. But try to get as many as you can, and try to push the lanes. And again, place as many 's as you can. If you got feeded during the Game, your enemies will probaly focus on you, in Team Battles, so be aware of that. you should try to get, Lizard buff, Golem buff and Baron's buff at once, for more Damage, Health and Mana Regen. And remember, its not always worth dieing for a kill, so think twice when turrets are involved. End the game, with a whole new Teemo, playstyle.
