Your opinion is nice, doing this build i'm don't thought that, its a good idea.But so black cleaver is before or later of infinity edge?

i say phantom dancer before black cleaver. because it gives in atk spped movemnet and crit. and after that i buy the blood thirster for attack and lifesteal. fully stacked it gives 100 atk and 25 life steal. and then first after those i buy black cleaver. and if you really want to handle your enemies. you will also need to boost his life and armor. but thats only my opinion :)
