This build will let you 1v9 the game, the enemy team will think you will go either ad or tank so in the laning phase the enemy top laner will take armor most of cases which will be an advantage for you, plus you have a lot of AP ratio and your pacif will give you more attack speed since his passif attack speed scales on how much ap you have and also your e and ultimate also have a lot of ap. With your Items there will be a very good synergy.
