What do I build on Teemo?

You should build mage item on him and transform him into a mage so he can spam double mushrooms. He is good in a poison comp.

Teeemo?! Where?!

what lane are you playing him in?

It also depends on how you want to focus your build. He has auto-attack based builds, as well as mage-y, trap-y builds.

I like Dark Harvest on him, since his early damage is pretty good, and in a lot of matchups it gives him solid scaling

aery is another good keystone bc his poison can reapply it, and is some consistent extra damage.

this is the team fight tactics board, not the league of legends board

Also, putting a Frozen Mallet on Teemo is kind of brutal...
