Olaf is a very all-around late,mid,early game champion. He is able to sustain very long making him a viable top laner who can destroy with its sustain making him last longer and making him trade more effectively. His build may seem awkward but in my opinion it has dominate and making me win 5+ games and just one lost. Olaf can even get a pentakill just by soloing the team alone, but do not risk it only do that if your very ahead and your opposing enemy side is behind. Olaf can very be effective in teamfights as people will try to target him but they won't realize that Olaf can just keep stealing life into himself.

I'm Hashtagfancy. I may look like some idiot who just put random stuff, and thinks he is pro. Although, I'm not ranked player I know that this build works is because I've tried it multiple times and I've been specializing in mostly top lane.

I have no so much to show because I'm not a very good guide/build making guy, but surely this will help if you can be very aggressive; although, if you poke too hard won't make you veyr ahead as you'll lose much mana. Olaf can be very mana hungry if you understand my mind.
