This build is for anyone that want's to become good as master yi and fast.It is meant for running in to battle and killing everyone that gets in your way

I usaly atart off in top lane or bot never mid ( because most of the guys in mid are distince shooters when iam a melee guy)

First you should start off by buying the boots so you can chase people down quickly, then when you have 600 gold it is a good idea to head back and buy the Berserker Greaves for the speed and the attack speed ( if you want you can save up an extra 1850 before heading back and get the B.F Sowrd).
After getting the BG you need to save up for the B.F. Sowrd for the Black Cleaver because it will lower the enemys armor making you and your teams hit harder ( if there a close courters melee character).
Then its a good idea to buy Fiendish code for the AP bouns, then buy the Narshors Tooth, because its always good to have alittle AP
Then buy another B.F. Sowrd to make a Blood Thrister for the AD and the life steal
Then buy a zeal and save up for the Phantom Dancer
And finialy finishing the build off by buying yet again another B.F. Sowrd and upgrading it to a Infinity Edge..... but by this point the game is eather over or the other team rage quit or surrendered lol
If you want you can sub in the Ghostblade in for the Infinity Edge because of the affect the Ghostblade gives you its like having two Highlanders

The thing i like to do is use my alpha strike on the enemy champs so im right beside them when i finish the attack for a few more attacks before he/ she can run away. It is a good method to get ganks early off in the game. When in Team fights its good to start off with the nukers or casters starting off with the healers, then nukers , then support, and finishing off with the tank (like any other team fight)

You can go in to the jungle when ever you want say if you want to get the blue and red buff which will help you out alot.
