So, you are not taking our constructive criticism. That tends to mean a downvote from me. Listen to people who comment as they are trying to make it into a better guide.
"a guide could just be a list of the items you need to buy and nothing more" A guide is a guide. It says that in the name. You are supposed to guide newer players not just give them a list of items (which I think are bad)
"And even then It might just be a bad guide because I dont play the same way" If a guide dosn't work for people then it is a bad guide. Guides are supposed to work for people other than you.
"Also, I find Liandry's is sort of useless" Liandries on teemo is super powerfull. It creates a huge amount of damage on your poke and it makes your shrooms do a ridiculous amount of damage.
"And it really doesnt add that much damage to either of those" Is 12% of their health not a lot of damage?
"It is better to just build more ap " Liandries is an AP item!
"And I put up Aatrox because he was the first champion listed. no other reason." You were just making your guide more complicated without adding anything.
"but if you read the guide it tells you that it is an alternative item..." I will show the flaw in that logic. "a guide could just be a list of the items you need to buy and nothing more". If you want people to just read the top, make it so they only have to read the top. You should also have a purchase order, not just a set of final items.
"And to that giant post up above...So many things you didnt read. So honestly, thats as much response as you deserve." I read enough to see that this was a bad guide. I gave you some pointers to work with to improve it and you ignore it.
" Even if the guide looks ugly. I told you I am not good at that kind of stuff." If you can't do it properly, don't do it. If you make a guide you should be aiming to make it the best one, otherwise what are you adding? Someone could go to http://www.mobafire.com/league-of-legends/build/teemo-ap-yordle-of-doom-3-8-updated-209977 and find a higher quality one.

Don't bother turning down help.

As the maker of this build... I have to ask... Did any of you actually TRY the build before you started being rude? I mean really, a guide could just be a list of the items you need to buy and nothing more.

I know that I dont even vote up or down any guide/build until I have tried it. And even then It might just be a bad guide because I dont play the same way.

Also, I find Liandry's is sort of useless. It only procs on the Mushrooms and your Q. And it really doesnt add that much damage to either of those. It is better to just build more ap to help with Teemo's overall damage, versus just one thing.

And I put up Aatrox because he was the first champion listed. no other reason.

I think the comment about the seventh item was a troll response... but if you read the guide it tells you that it is an alternative item...

And to that giant post up above...So many things you didnt read. So honestly, thats as much response as you deserve.

But back to my main point. Even if the guide looks ugly. I told you I am not good at that kind of stuff. Just buy the items, use the runes and the Tree build I suggest, and THEN come back and say what you will.

It is just ignorant to assume that the build on its own is bad.

Also as a side note, if you are smart enough, you dont have to worry about surviving an encounter. many a time have I killed champions without them even dealing more than 300 damage to me. When played properly Teemo, to me, is a very good burst champion.

To me is a simple fact. when your basic attacks are dealing about 600 damage per hit, plus any bonus damage... and you attack almost three times a second. people dont even have time to react to you coming out of stealth, or when you wander out of the bush...

Just archive this dude, :l. It just seems so wrong.
Clarity is just sooooooooo wrong...
Have you even read Laggermeister's Clarity mini guide?
You should. :l

Because MOBAFire already has one top rated [[teemu]] guide.

Or archiving it and pretending it never existed.

What's the point of having this build be named about shrooming when this is a hybrid build with little mobility and no Liandry's. The shroom damage will be poor, it will be dangerous to place them, and it will waste time. There is absolutely no reason to have Aatrox listed as build here. There are so many things wrong with this build, you should consider reworking this entire thing.

So are you supposed to hold the seventh item in your *** or what.

Problems:
No boots on teemo. Teemo is about chasing and getting as many autos off in that time. TO dramatically increase the damage, buy boots.
Scaling runes don't do anything early and late they don't make much difference. For example your seals will give around 10 ad late game. If you use what is generally the only seal, flat armour, you will get around 13 armour meaning you are more likely to win trades and so will probably be able to afford one extra long sword late game.
For AP teemo you generally should always buy a liandries torment because it makes his shrooms hurt so much.
A teemo with no defensive runes or masteries will be so easy to kill.
Missing most sections like pros/cons + teamfighting
BBCode is important for a guide. I did not want to read it because it didn't look appealing. It is surprising how much difference it makes.
"For Teemo these are better than the Greater Seal of Attack Damage" they are still worse than seals of armour
"Teemo is what I call a "Snow-ball Champion"" Teemo doesn't snowball anywhere near as well as loads of other people.
" By that I mean Teemo starts off small, but ends up bigger and more dangerous the longer you are in a match" so..... just like everyone else? (also sounds a bit more like zac or cho)
", great for Teemo's "snow-ball effect"" Scailing runes aren't as good as flat runes for snowballing. Someone who actually snowballs has trouble with starting the snowball so flat runes help them with that. Someone who is bad at snowballing would be more likely to use scailing as it will boost their weak late game.
"So to address this problem, I get the Clarity spell." I have never run out of mana as teemo. If you need clarity you are doing it wrong.
" It heals you. Nuff' said.

Barrier can also be functional," in almost every situation barrier is better than heal.
"I am not sure if it blocks damage from Turrets" it does

Not going to finish this comment, you have enough to work on for now

Runes of scaling fail

If I were you my friend, I would archive this before anyone else gets to it. It just doesn't live up to the site's standards.
