Try Lissandra, she can actually destroy Akali. Your q has longer range than Akali's q, so you can poke and avoid being poked. You have aoe to reveal her location in the cloud (take arcane comet ofc), and you have short cd on q to really hurt her once you see her location. You also have e to get away, and strong ulti to either lock her or save yourself. Plus, when she makes the mistake of teleporting to you with her e, you can again root her (especially good when she does it under your turret), and kick her butt. Try it, really, it worked for me, Lissandra counters her so nicely...and she's not very common/expected, so she probably won't be banned and Akali might not know what to do vs you.
