Moolistar is ultimate Akali weakness

Step 1) pick Step 2) profit

In all seriousness Ali star is the bane of akalis existence, even if she hits 6 she will never go in because alistar can use Q and W her into turret, or just W her away, which conviently puts her out of range of shadow dance, and if you ever fuck up you always have your ult or your E which pretty much guarantees that you get away, and your passive gives free sustain against her q spams, if this is not a absolute counter I do not know what is. Works best mid lane, full ap with lich bane and ludens, maybe a morello if you feel cocky. If you don't believe me try it out right now and watch alkali mains ban alistar for the rest of theirs LoL carriers

Or you could just play malzhar. Up to you.
