Teemo is just to op. With him being able to sit invisible and be undetected and BOOM! he pops out and kills. And his shrooms are the killer XD with a slow and damage per second they are the one thing they will fear the most.

If ur like me you can get kills early game if not first blood. If ur getting kills early u should invest in gettin a mejai's soulstealer. And the Void staff is for the people who like to build magic resist to try to counter ur ap.Morellonomicon is great for ur mana regen since ur shrooms like to eat up ur mana, and the cd,ap,and its passive on it is nice. The liandry's torment is great for him because of the mp,the extra health,and its passive is great for the sutained damage. Th edeathcap and the hourglass is awsome for all the ap it gives u plus the hourglasses passive.

Farming with teemo is crucial especially if u are solo lane with him. Try to work on his last hits so u get the ensure kill of the minion. Also with farming with him u need to try to have more minion kills than the other champion ur lanning agaisnt. This will matter because the more money you have hte faster you can get your items before them. Don't be scared to run out and get u the kill but be cautious of your surrounding =s because if you are doing very well the jungler most likely will camp in ur lane.

It is crucial u set your shrooms in high traffic areas. But dont forget to save u one for a team fight or a 1 on 1 fight.Like setting ur shrooms in the bushes beside the lanes to prevent u getting killed from ganks or if they don't step on it, it will still show they are coming and it will help your teammates from getting ganked to.
