Playing against Teemo

How to counter and exploit weaknesses

1

Buy Oracle Lens fast, it reveals and disables Teemo's mushrooms.

2

Q (Blind) has an 8s cooldown at rank 1: engage right after he uses it if you're an auto-attack champion.

3

Teemo has no dash and no hard CC — ganks and forced engages are very effective against him.

4

In the late game, buy Control Wards to clear mushrooms before contesting Baron or Dragon.
