Teemo's mushrooms can be used to farm creep waves very effectively.
Place your mushrooms at key locations on the map, such as by the Dragon or Baron Nashor, to reveal when your enemies might be attempting to kill them.
Use Moonfall and Lunar Rush to stay on targets and activate Moonsilver Blade for extra damage.
Consider when to cast Lunar Rush without Moonlight and when to wait for another Crescent Strike.
Landing Crescent Strike is critically important, but don't be afraid to miss. The cooldown is short and the mana cost is low.

Overall, Teemo sees a very large drop in his KDA (ratio of kills and assists to deaths) when paired with Diana. His KDA fell from NaN to NaN.

When Teemo tries to synergize with Diana, he gets a small decrease in his complete damage dealt. This difference could signal that Diana does not provide protection for him to deal more damage or that her support also helps extend the round's duration. Similarly, when Teemo is played with Diana on the same team, he usually scores many fewer killing sprees than when he plays on his own. This is contrasting evidence that he is worse when playing synergisticly with Diana.
Moreover, when Teemo plays with Diana on the same side, he typically takes a little less damage than when he plays alone. Taking not as much damage may mean that Diana does a decent job of covering Teemo during teamfights.
