Shooting whit sword
Berserker's Greaves - I think this "shoe" is best for AD master yi
Phantom Dancer - This one for a great attack speed
Infinity Edge - It's good for a damage
Phantom Dancer - Another one ! :)
The Bloodthirster - A little bit lifesteal you need , belive me :)
The Black Cleaver - You'll need health and it's giveing you more damage too !
I think that the best summoner spells for master yi are Flash and Ignite
