Only fooled around with the idea in training mode, so this isn't something that I've used much in any real match... but it seems decent enough to have me wondering why I haven't. It's a pretty simple thing, but does anyone use (non-flight canceled) j.MK to ground themselves quickly after their grounded opponent blocks j.MP? It seems pretty good. Can be used to land 1, 2, or 3 hits of j.MP, hit the ground using j.MK, and depending on how close you are you can try and quickly mix them up with a low, or trap them with c.MP and use a stinger canceled flight into j.lk. If you go for a fourth hit with j.MP and get pushblocked, you can ground yourself quickly and dash in to continue pressure. On hit, it can used to quickly reach the ground and start a ground chain starting with almost anything (including buers if you want) depending on how high up you were before you canceled into j.MK, and doing this seems to provide more damage than j.MP>fly>j.MK>groundchain, even if it isn't a completely huge difference.
