How Do You Kill Leblanc?

Seriously this chick drives me up wall. Fed assassin? Whelp you better aim him/her down so they don't wreck your squishies and play around them.

Fed Zed? QSS/Zhonya's CC him after he uses Death Mark so he can't apply damage.

Fed Talon? Pink Wards, Sweeper Lens blow him up before he annihilates your carries.

Fed Akali? Pink ward who silly circles and lol at her as you destroy her.

Same methods apply with most other assassins. But I swear LB's elusiveness is like Zed's on crack. She can cover so much distance pop your carry then go back a screen away instantly. And when you actually do catch her! Unless you blow her up instantly she disappears for a moment, then splits into two....and here is the kicker I always get juked....like always! (seriously tell me the typical tell tales signs of whose the real one)

Wukong is a juke master also but he can't cover as much distance as LB after the juke. Shaco plays the same mind games but.....you don't really care too much about killing Shaco. If you let the LB get away there's is no telling when she will just pop back out and delete someone else while your guard is down.

So any advice?
