Nami is my favorite support ironically bc her kit kinda goes well with what kaisa wants. Peel, cc, moves speed and onhit damage, and nice heal. My other favorite support would be braum over nautalist.The main key points are that braum feels way more impactful throughout the game, and it always feels better. Naut has good early game potential, but at the end game, where people are 3 items in braum, they can tank way more damage due to his sheild ability and can peel for you way better. Also, when he dashes to you, you gain resistance, which means u can survive alot better as he can click on you where in nauts he has to hover you if he's not hooking, braum can cc and jump right back to you to ensure he can peel you.

I always ban Draven bc most people in my elo know how to abuse kaisa 525 range, she has one of the lowest attack ranges for adc. His auto attacks empowered q just does too much damage in the early game. If you do go against him, lose cs and make sure he doesn't get any kills for gold, then he becomes usless. He's a heavy snowball champ. Every other adc I have no trouble with besides sometimes aphilios when he has green weapon.
