Since you are basically an adc in mid lane, try to save your E as an escape tool; if your enemy jumps on you burst him with a quick W, right click and then Q to scare them away, focus on farming before level 6 as your ultimate is a good portion of your damage, try to use your ultimate like a Neeko, jump them and use it to deal damage to as much enemies as possible, don't hesitate to use your W to farm. A good tip is to gank bot lane when you get level 6, that way you will have your R and they won't; making them easier prey to catch.

If you have any questions comment and I will try to update this post and answer them.
