Go harras the enemy champion . First hit your slow spell (w) then hit your q spell on him and after this run and heal yourself with your heal spell (e). Just harras and wait for a gank . If your enemy is low Hp , go dive him with your ultimate (r) and kill him with your ghuls/ignite . Flash out if you are low . Now you are going to buy these items u can see in the top and go on lane . Dont forget a ward which u place on the river . After 1 kill the 2 kill is easy , just harras farm and dive him , but care of the enemy jungler . good luck
