I play him support. Standing on the bush and abuse the  stealth, you almost claim its as your territory. Put a ward on the other bush so that you are not poked by the enemy team.

Finding chances to run out, auto Q auto the ADC for a good poke and maybe denying some minion. With your movespeed from passive and atk speed from breaking stealth, it could be easy for you to do that.

The fact that you are stealth also affect the mental of the enemy team. They almost forgot you are in the lane while if you solo-lane you must farm. And also, when you leave, they still think you still claimed the bush, giving your ADC fake safe zone while you gank or buy stuffs.

Once you have ultimate, using mushroom as your ward, blocking gank from the enemy team. Also, wandering around giving sight of the enemy jungler route. Sometimes, you may get a random assist just by doing so.

For item, since playing support, you don't need to build damage. Instead, you can build Mage Tank Build with Rylai, Liandry so the mushroom is a bit more painful and a bit CC in teamfight. For boots, I don't buy sorcerer. I buy the one with the out-of-combat movespeed so I can rush to teamfights when I was wandering putting mushrooms.

For damage build, since R is situational and Q is single-target short-range CC-main spell, E is left as your main damage output. Build Nashor Tooth for attack speed and CDR for more darts and mushrooms.

You can also search builds on online guildes and Teemo wikia post.
