I dont think this uild is the way to go. Shaco should in my oppinion be build around his Decieve skill, where you seek to enchance the other s if you can.

My usual build goes like this and works most of the times.
Mobility
Infinity Edge ( goes like BF-->Pickaxe-->last item(dont recall its name)
Phantom Dancer
Bloodthirster ( get lifesteal item before Phantom Dancer)
Madreds Bloodrazor
Last item depends on the tank. If lots of armor go Last Whisper. If no designated tank go with Either Frozen mallet or another Phantom Dancer.
Runes all Cirt Damg, xept blues which is mana regen or level.
Try it, works ofthen

Pretty nice if game ends fast. In late game all got a lot hp and it's hard to kill somebody. I got 4.5 items from the list and I was dealing 993 dmg from poison-shiv. But I don't know what is better dmg or AP build.
