First start out wif shoes as you got runes to support you for your early game. Get 5 hp pots incase of any gang also add your spin to run away easily.Get Avarice blade next as you need more critical to poke those tankers. Next get Zeal it gives u more Critical rate and also more attack speed so u can continue to poke your enemies. Get brutalizer as it gives u armor penetration and a few attack damage, Note try to save your spin as they might gang you and u have no way to run unless u get lucky. Turn the brutalizer into a Youmuu ghost blade It has armor penetration and also its activate gives u speed to chase those low hp if they are able to run from your slow. Get Infi edge, Why infi edge before BT? as you are soloing top by the time u have IE u shld also have your ulti, when a member of yours prepares to gang your IE would be a great help combined with your youmuu ghost blade. Get BT For life steal (try to max stack before getting into any fights as a few % does a great help in battles) Get one more Phantom dancer for more critical and attack speed, finally for your last time Get another BT If the other team are full of tanks, You might wan to change one of your PD/BT into a last whisper or a blood razor, This is my first guide hope you enjoy leave any comments or suggestions you think that it might be useful for me in the future :) thx~
PS:Sell your shoe after u get your 2ND PD
