How to beat Ahri as Cassiopeia: the early game

Level 1 favors you — Noxious Blast poke outranges her Orb of Deception trades and you can zone her off farm from level 1. Levels 2-3 are a genuine skill check: whoever lands the first Charm or dodges the first Q usually wins the exchange, so trade cautiously and watch her mana for Charm windows. Track Charm is a flat 12s at every rank — that is your whole window, so step up the moment it misses and punish with Q into E spam.
