I'm not going to go in detail with this guide... for one thing i don't even own teemo i just use him when he's free to play, and that's only in dominion. this guide is what i came up with at the top of my head.

This guide was made for dominion so in this guide i will tell you the best places to put shrooms to maximize trolling. First off you place shrooms on ALL health relics, and also the speed buffs... when done correctly the enemy team will RAGE and call you a noob... that's what we want... to get the enemy as MAD as possible. of course you also want to put shrooms in the brush when ever possible. But my tip is... always keep at least one shroom with you... you never know when the enemy will start chasing you, and you might need to place shroom to help make a swift getaway
