Hello all,this is my first build and i hope you will like it and why not try it out :)
It focuses more on nuking and 2 shotting an opponent champion,that's why it loses some points in survivability

PROS
-Perfect in mid lane-
-Can get kills really easily-
-Can survive a gank easily-

CONS
-Really Squishy-
-Most of the times the first target in team fights-
-Sometimes might have mana issues(depends the player's playstyle-

I choose clarity,because mana is your worst enemy.Basically with clarity you can keep laning for as much as you like.
Flash can help you really good,you can start a gank and you can even survive a gank.I know a lot will say that using your w ability is enough along with your ulti,but trust me flash can most of the times guarantee the life of your champion.

Her passive is really great,might be hard to believe it but it can save you almost every time that you reach low hp,it can really confuse the opposing champions.
This is your primary nuking ability,with this along with your ultimate attack(mimic) you can 2 shot an opposing champion without even notice.
Distortion for me is your opener ability if you want to kill an enemy champion,along with sigil of silence followed by Mimic will definitely earn you a kill.Though you will also use it for escape purposes as it can cover a good distance.
Ethereal Chains it's not that appealing for every person that is using LeBlanc.I find it really usefull though,you can keep an opposing champion in place,which will be a nice target for everyone in your team to kill if not just you.
Mimic basically cries out to use it after Sigil of Silence.It will surely make the opposing champion cry :p Though it can really save you when using it after distortion to avoid a death.

Farming with LeBlanc is not that hard as some may think,you can easily do last hits with her normal attack.

Distortion if timed correctly can give you some creep kills easily,especially in late game it can clear a whole pack of creeps with just one jump.
