OK first and foremost this guide is used mostly for shorter quicker games. It is designed around farming minions for coin early game, and being able to do damage to multiple enemies mid-endgame. This build works great for 3 v 3 or 5 v 5.

This is mainly an heavy AD build. I also have a hybrid version that replaces the wits end with a Nashors Tooth, and the Bloodthirster with a Hextech gunblade.

Pros:
Deals lots of damage
Damages multiple enemies
Sends out damage at about 2.3 aps
High Sustainability
Makes gold very fast
Great for team fights.
Poison is extremely underrated and gives that extra little bit to get the kill.
At lvl 6 you get Shrooms which can double up as a sight ward.
Blind makes 1 v 1's extremely easier to win
Teammates with teleport can go to any shroom that you have on the map

Cons:
Squishy
Tend to get targeted first
Teammates get mad due to easily able to KS them.
Poison doesn't do as much damage to high hp regen tanks.
Full AP champions(ex Brand, Fiddles, etc) don't deal as much damage using basic attacks so blind is useless against them in straight up conflict situations.

Depending on if I'm playing 5 v 5 or 3 v 3 is the spells that I get.


Ghost
Ghost combined with Teemo's Move quick makes chasing down or getting away from enemies extremely easier.

Heal
I like heal because of its great uses early game as well as for team fights. Using heal at the correct time can save an entire team from getting killed. It is a useful spell to have around if you don't have a support character.

Other Spells You could use.


Ignite.
I feel that I don't need ignite due to being able to dish out so much damage so fast with this build. Its uses are great for 3v3 early game, but after that it's practically useless to me.

Teleport.
I use this spell alot in 5 v 5 simply because of map size. Little known fact is that you can teleport to any shroom that you have on map. I fully recommend this if you don't want to use Ghost.

Flash.
I don't really care for this spell to much. Yes it can get you through a wall, but it seems like everyone uses it these days. Ghost lasts much longer for getting away, and Teleport can get you anywhere on the map that is in your or a teammates line of sight.

Teemos blind skill is one of the neatest abilities in the game. At lvl 5 it gives you 3 full seconds of freedom from basic attacks from one champion. With this build 3 seconds is all you need to own most in a 1 v 1.

First I like to get Dorans Blade. Has a little bit of lifesteal, some extra Hp and Hp regen.


Secondly is Berserkers Greaves. These are a no brainer for this build.


Thirdly is your Recurve Bow. When you get this item you will be ready for increased attack speed.

Fourth is Vampiric Scepter. You will be glad you got this little guy I promise.

Fifth is upgrading you Bow and getting an Ionic Spark. This is where you start dealing AOE damage. Which is what this build is centered around.

Sixth Item: Get the Stinger for the increased attack speed.

Seventh upgrade to the Nashors tooth. This item is awesome, Ability power, Attack speed, Mana Regen and 25% cooldown reduction.

At about this point in the Build I sell the Dorans blade and Get a Tiamat. This badboy gives 50 attack damage, 15 health regen, 5 mana regen and the passive gives your passive attacks splash damage, Which makes ever single basic attack a miniature AOE.

Next get another Recurve bow. 2.2-2.4 attacks per second at this point in the build.

Upgrade the Recurve bow and get a Madrids Bloodrazor. This item is a must have, 40 more attack damage, 40% attack speed, 25 armor, and does 4% of opponents max hp bonus magic damage. So you are in a 1 v 1 with volibear who has 5000 hp. each basic attack is doing bonus magic damage of 200 on top of your basic attacks, on top of your poison per second damage, on top of every other second your ionic spark is dealing an additional 110 damage.
What this item basic means is you rape your enemies.

Last but certainly not least Is upgrade your Vampiric Sceptar and get the Hextech Gunblade. Attack Damage, Ability Power, Lifesteal, and Spellvamp....Can you say GIGGITY???
