Graves does well against her, since his buckshot almost always gets her, early game at least. Trist also works well against Kalista, since her damage is more upfront. As a main support, the best one to counter Kalista is Taric, and no, I shit you not. Point click stun, gives his adc a bit of armor and heals them, everything a Kalista hates in one bundle. Naut is also a good pick against her, as the amount of CC he brings means that if he catches her, or uses his ult, she is dead. A good Lulu will piss any Kalista off, since her W is basically a "fuck you and your rend" button, and her shield annoy Kalista quite a bit. My last (but by no means least) pick against her is Karma (whom I main). Her poke is wayyyyyyyyyyy to much for Kalista to deal with, her W is point click and her hopping won't get her out of its snare range (she has to walk, not hop), her shield is annoying and it makes her have to land more stacks of rend, if timed correctly.
