So this is my best build ever for a Teemo hybrid. When i finish this build in game,there is no one that can beat me in 1v1.

If you take a close look to my masteries page, you'll see that they all have ap inside. And that's where the good part starts for me. I start with 7ap and in the first ap item i'll get, my ap rises up to 20 or something really close to it!

The build that i use ,i believe it's really complicated. Every person -not my friends- that see me use this build they say "wtf" etc etc. But it works for me!

So this is how it goes:

1. Doran's Blade
2. Berseker's Greaves
3. Trinity Force
4. Hextech Gunblade
5. Infinity Edge
6. Bloodthirster

So i start with Doran's Blade just to make sure that i'll have 69 attack damage. It's not like a huge amount of damage but it will rise when u go lvl 2.
Berserker's Greaves. The boots that i almost always make in AD carries. But you can also replace them for some nice Mercury's boots that give you more tenacity but i really like the attack speed that these boots give.
The Trinity Force. The best item ever for an AD carry that can really use some AP too,such as Ezreal, Teemo or Corki. Gives you everything!! Health,Attack Damage,Attack Speed,Mana,Ability Power and that massive op Phage with it's really op passive! I love this item <3.
Hextech Gunblade. Well this is an op item for Teemo too. It gives you lots of Lifesteal and Attack Damage and Ability Power!!! What else do you need? Oh wait.
The next item you will really really need is the one and only Infinity Edge! I don't think i have to say much abou it. TONS OF DAMAGE.
Finally the Bloodthirster. Pure Lifesteal and even MORE Attack Damage!!

At the end you should sell the doran's blade. Normally i do a second Bloodthirster or a Black Cleaver but there might be games that you will need a Guardian Angel instead or more Armor/Magic Resist. Just chose the item wisely so it can help you in the teamfights!

For the skill sequence,everytime i start with leveling up the Blind at lvl 1 cause u never know what is gonna happen. Blind can prevent your AD enemies from doing you tons of damage! After that i take for lvl 2 my poison so i can make much more dmg. Lvl 3 and i get quick move so if you haven't got any boots until lvl 3 it would be a nice skill to use in order to catch up an enemy or get out of their sight. I usually max my poison as soon as possible but it depends on my lane. If my enemy AD is really strong then i'll get an extra lvl to Blind. At lvl 6 i get my ultimate and spamm these shrooms everywhere!

this is a sample. Just imagine that my "support" was soraka and he fed really bad the enemy carry and i also died many times but it was just a matter of farm :P
