i start with dorans cause is a good item to start the game and even better when you start with bloodlust then take the shoes for attack speed and then phantom dancer for the critical chance and the bonus attack and movement speed makes your trynda so good then buy a infinity for more powerfull attacks and critical chance then buy again phantom dancer then trynda will be so powerfull he can go fast to teamfights and kill all the oppoents easy then buy bloodthirster for some more ad and some life steal then you can finish of with the black cleaver if you want some more attack speed or with one more bloodthirster
