Hey, well it works pretty much with every "combo" that has WP 1B+K launch. But like I told you two months ago, it's not for VS actually :] It's far from being guaranteed. It's the same thing like SC2's WP 3A+B:iCS or SW FC 1B:iCS (works with every character but opponent has to be launched from crouching position) (I added this to my SC3's movie credits - here at 4:09 )and SC3's SW FC 1B:A+G_B+G (I have never done this one, but Nemeton from France recorded it. Supposedly there's 1 frame window for throw to connect when Ivy is in certain angle) Also, thanks to this I discovered something else... the bullshit of training mode. Even if you set your opponent to do nothing, he will still hold [G] during the fly (after WP 1B+K) and that's why you can catch the other character with CS/iCS/A+G/B+G without setting the ukemi on.
Then its a tech trap, not a combo. Although, if they don't hold G (and consequently tech) after WP 1B+K launch, then you can relaunch them with another WP 1B+K can't you?
