Not Updated For Current Season
The masteries shown here are not yet updated for the current season, the guide author needs to set up the new masteries. As such, they will be different than the masteries you see in-game.
to my LeBlanc guide - hope you enjoy it :).
This build will give the enough Ap to kill any Champion.
