its a season 2 guide *facepalm*

Very good build i was mid vs fizz and i kill very easy fizz

the first time i had played teemo i buildet him - before reading this guide - the same, but with an other item order. the final equip was the same.^^

i would make some differences in runes and masteries.

1 Mastery

You choosed to take "Lethality" (+10% CritDmg).
Why? Teemo has no passive Crit Chance like Pantheon has against targets below 15% health.
Also you don't gain any Crit Chance from any items, or Runes/Masteries.
Result: 0% Crit Chance, but +10% Crit Damage skilled. Wasted point.
Put it into "Vampirism" for some more sustainability early game.

You choosed "Havoc"(+1,5% damage) to come into the next Tier.
Put this together with the point from "Leathality"/"Vampirism" into "Blast"(+1AP / level).
This will increase your damage through your E on every hit nearly the same as "Havoc"(every dot tick will also be as nearly as the same) in the mid/end game and in the early game this will be much more. Your damage dealt from the shrooms and the Q also be increased.

Another and also the best possibility would be, to use this 4 points and one other from "Deadliness"(9AD on 18 to 7,25 -> 8) to maximize "Sorcery"(4%CDR) to get "Arcance Knowledge" skilled.
This 10% Magic Penetration will consult in higher damage from your Q, your shrooms, every E tick, and the bonus damage dealt through "Malady", "Wit's End" and "Madred's Bloodrazor" making this items much more effective without losing any performance early game.

2 Runes
I also do not understand your Glyphs (Blue Runes).
They give 0.24 AD wich will do 2.16 Damage more every auto attack before scaling with armor.
The early game armor will make about 20-30% depending on the other cahmpion and his/her runes and level.
so.. this are just 2 damage every autoattack (every ~1.1 seconds on level 1 WITH atkspeed seals) after scaling.. That isn't very much, isn't it?
If we would take flat AP Runes here, we would get 10.44 -> 11 AP.
This is:
+8 Damage with Q
+8 Damage with R
+2 Damage with E hit and another 6 with the following 3 ticks (together also 8).

seems to be a greater boost, especially because the MR normaly is much lower than the armor early game.

3 Build Sequence
You choosed:
-Doran's
-Berserkers
-Frosthammer
-Nashor's
-Malady
-Wit's End
-Madred's

Why not:
-Doran's / Boots + 3 Healing pots
-Boots->Berserkers
-Phage
-Malady ..\ Deals more Damage
-Wit's End ../ during early/mid than end.
-Nashor's Tooth
-Bloodrazor
-(sell Berserkers -> Mercury Treads)
-Phage->Frosthammer


Building an Frosthammer earlygame will be too expensive to kill effectively.
No attack speed, nor high bonus damage -> no kills except luck/killstealing.
Phage will give live, ad, slow. this is enough performance for early game.
after that you'll need more attack speed, ombined with more damage per hit.
malady is cheap, so get it.
your blind works against AD well enough. But what's with AP?
Get Wit's End to counter them with MR, combined with additional damage per hit and much needed attackspeed.
Time to pimp up your E and other skill damage by increasing your AP and MP5-Ratio.
To get this and mooore Attackspeed, get Nashor's Tooth.
Now you have enough Attackspeed, quite good damage, but to use this high atkspeed ratio, you have to get damage per hit again. And wich item is best at damage per Hit? Sure. Bloodrazors. Get it.
bonus AD + 4% enemies life magical damage per hit.
Now we should have too much Attackspeed. 2.5 hits/second is lol's maximum, we are over this.
If you want, you can sell your Berserker Boots for Mercury Treads or Ninja Trabis, gaining more survivability.
And last but not least, we upgrade our Phage to a Frosthammer to gain more survivability and a better slow.
