My Twisted Fate build?

Hey guys just picked up Tf not to long ago and wanted to share my build, pretty standard with one controversial items. Oh and I always take teleport on him late game, for back dooring purposes and more map pressure. Anyway I genrally start with flask and 4 pots, yes I wait the extra 10 gold. From there if i back before 1600 I build lichbane first if I have 1600 or more I build my rabadons first. From there Ill buy sorc boots then either rabadons or lichbane whichever I didnt get first. After that I go into there three items depending on how were doing. If im getting focused hard Ill go into a zhonyas. If they build Mr ill go void and if not ill build a narshors tooth, yes narshors tooth. I think it helps when your split pushing because it increases your duel potential with the att speed and empowered autos along with procing e. I almost always get this as my 5th or 6th item late game for split pushing and backdooring inhibs and towers. so pretty much after my core (lichbane,rabadons,sorcs) ill go into those 3 and if i dont take narshors because im getting bursted and need a bit of hp ill build rylais so i can kite better with qs. Any questions, comments, or just any TF tips in general? I plan on maining him as he's pretty versital and can provide alot of map pressure.
