When facing Teemo, champions like Olaf, Comet Nasus, and Aatrox are effective counters; Olaf can especially nullify him with Phase Rush and Swifties.
Despite Teemo's strong early game, poor spacing and careless pushing often make him vulnerable to ganks and diminish his overall game impact.
Teemo's Blind skill is highly impactful, and in the late game, his mushrooms provide excellent area control and sustained damage.
