Lux with hextech revolver is hilarious.

You push her out, she comes back with a revolver, you step a bit to close to cs, she e's and auto's you, and then you lost most of your health. Then she types "Outplayed" in chat and there goes your 15 lp. I speak from experience here,but if you buy it, you pretty much auto win lane, and you have the choice between 2 nice items.
