About this guide
This guide was created from the AD items on the support Teemo page at http://lolalytics.com/champion/Teemo/Support/
The data changes from day to day, so this guide may be a little bit inaccurate.
Disclaimer: I don't play ADC Teemo and I don't recommend it. However, in the process of creating my Teemo Support guide, I ran across a bunch of AD items with relatively high win rates on "Teemo Support," which indicates that some people do play ADC Teemo successfully.
You shouldn't run the same build each game, but adapt to your circumstances. For example, even though Blade of the Ruined King is not usually a good item, it may be very good if the enemy team has a lot of tanks. Use the "Core Build" as a suggestion.
Use the items in the "items by win rate" section to adapt your build depending on what is needed.
