The items is pretty standard. Twisted fate is a attack speed character so why not use it?
Your text to link here... Is only for late game, when you need some life steal and with the crit and attack dmg its a pretty nice boost.
is the main dmg so dont be afraid to auto attack. This build also give you the chance of slicing tanks if you are lucky. Such as rammus, that will taunt you and Shen to. You will be pretty awsome against ad champs becuase you can "kite" them. just always remember to use your ult when you can. The cooldown is low so you dont "waste it"
Will be your surviver and good friend. First of all the hp boost and the slow thing is awsome.

will be good if you wants to finish someone of and use ult close to them. And ofc its a awsome escaper. Use flash away and fast use ult and drop of somewhere random.
Is for chasing or running away from one single guy.

uhm.. The runes as you can see is just for attack speed and some mana if you need it.
The runes will be a pain in the *** in the start for the other team. No body at all expect TF to be that fast.

When its team work time always put in the "Pick a card - stun" card on. Its giving some dmg and stuns the target in a high range. Your ult can also teleport you to your injured team mate and help him.
