Teemo Carry Advice on countering Teemo

1. Get Scanners and Pinks for Shrooms It's kinda sad to see how people never buy pinks and never use scanners. Put a pink in around a bush if you're top or bot put it near tower if you're mid Pink will help you avoid uneeded dmg.
2. Teemo late game will assassinate your Carries Careful of the Teemo Carry if Teemo Flashed he is most likely going for your ADC or your APC with 1 Ludens/Gunblade to his side they will kneel over for Satan
3. Don't leave your lane alone with Teemo Leaving lane alone with Teemo gives the Teemo time to build a Trap/Lane sustain and or get complete control over the lane to get your towers and since tower 1st blood is a thing you should really be worried now
4. Finish ASAP Due to Teemos Shrooms he can make the team comeback from the worst of times especially if he gets full build.
5. GG if the Teemo is helping his team A lot of people consider Teemo to be a lone wolf. His True power shows in teamfights where he will target backlines or reduce the heal of fronts to nothing and get his team some kills resulting in a team ahead of gold.

PS. This was made after I carried 2 games as Teemo and it was annoying that no one on the Enemy did this.
