Only way to do it right deceptively is to do the "no look" shot, ie. look one way but flick it another way.
A simple one to learn is moving towards the net looking as if you're going to lift the shuttle, then drop your arm and play the net shot, admittedly it's more of a delay than a deception but it works non-the-less.
Why not first just make all your strokes at the net look the same? I have no idea what your skill level is, but I think this is usually a first step in deceptive strokes. You can add in all the other fancy stuff later.
Do a search on YouTube for Lee Jae Bok, he has a video that explains it quite nicely. Or drop me an email.....
A fun thing to do with a net shot is to swing in one direction, but angle the racket face in the other direction. This is an intermediate to advanced shot that you should only practice after you have all the other basic shots down, meaning full court underhand and overhand clears, and regular drops/nets/smashes. So you swing say left to right for a net shot, but at the last second, slow your swing down, rotate your hand to change the angle of the racket face, and use a quick light flick of the wrist to send it in the opposite direction of your original motion. Since this is a net/drop shot, it does not require a lot of power, so don't be too strong with your wrist flick. This takes a lot of control and coordination, so please save your practice time for basic shots before spending it on this shot.
