i play with this build every time i play morde, and allmost every time poeple say that i'm a noob with dat lichbane and hourglass. but in late game it's allmost me who has to carry and lead teamfights. the lich bane is used for both push and dmg. when you destroy a tower or any other structure, just throw a random E for activate the lich bane. and if you go around in the jungle and meet someone 1v1, the lich bane with Q is gonna destroy them. so a full spell combo against a fighter is allmost gonna kill them.

i didn't set any sommunor spells in because i think that spells should be thosen by the player it self, depend on wich spells they are used to use.

i know i might spell something wrong and i'm sry :)

pros:
extremly high burst 1v1 after first 4 items.
very good farming.

cons:
if you get stunned or silenced or supressed, you are dead.

you might switch that hourglass for a quick silver sash, after what your enemy team deal most dmg on.

this build is exspendsive(cost a lot gold) so if you are under fed, you can go and farm alone, and jungle.
it is still important that you are there in team fight and try to get some assists and kills for more money.

if you get focused in teamfights you might wonna use your ult on their ad carry for get that shield to get up faster. but if not get focused you wonna ult their ap carry, because of your ult give you some of their ap while the clone is alive.
