Ok so this is only my first guide but ive been using this build for a while and it works really good. I normally dont see many people using shaco as attack speed but if u add some damage with his attack speed it is the best thing ever sence when he auto attacks he hits 2 times when u have madreds the first is ussaly for 130-160 depending on the persons armour and then the second is ussaly about 50-70 so not as high but it still hits pritty hard and when i finish this build i ussaly have about 1.9 attack speed so thats a lot of damage output.

Ok with this build you should try to avoid 1v1 unless the person is squishy then you should be able to take them on in a fight. Shaco is very good in a team fight unless he gets focused becauase of his huge amount of damage output.

There to ways you could us ur ult. The first way is when karthus or ashe is about to hit you with there ult u can pop urs and you wont get hurt by the ult because when he uses his ult he disapears for .5 seconds just enough for the ults to miss. The second way to use this is the make your damage output even more. Also when the ult dies it blows up so you can farm minions that way if u get the minions near it.
