How does one become good on champs like Malzahar?

they press e

knowing what to do and when to do it.

playing them a lot until they get used to them.

build 1 item then spam e and ult whenthey are low enough.

practice a lot and knowing when and on whom to use ur abilties is a start

Thanks for the advice guys. Now how about Annie? Any mechanically gifted Annie players here?

Play safe and AFK farm. Don't max your %HP damage until last unless its your only poke/damage.
