Massive burst champions/ champions that outrange her will all counter Cass. Assassins are great, however as most of those need dashes to get to Cass, you got to be very careful with her W and ult.

I find Syndra and Lux in particular are extremely strong counters. Syndra can clear the way very fast while Cass is not the best at pushing. Every single QE stun that hit will turn into a kill (as you can easily walk up, W, ult, ignite and she's either dead or go B anyway). Lux has somewhat lower burst, but much harder to avoid poke and also good waveclear. From mid, late game, Lux is always out of reach from Cass and she will snipe Cass (as well as other enemies) from afar.
