Drain half the opponents life from a simple cr.mk poke using one meter.
Sure, you can poke around with Kazuya’s standing hp into 5xewgf, however this method gives you little more time to prepare the electric sequence, and Ken’s cr mk covers a large distance and hits low
Of course, you can cancel many of Ken’s normals into hk tatsu and bring in Kazuya for max damage.
At least give the man a towel so he can clean himself up.
Twin Snake Smash xx St. Fierce xx EX Slaughter Fist works the same way, btw. Pretty sure you can fit most, if not all, of the EWGF sequence into it. I’ll have to double check though.
