EWGF is signifigantly easier than Tekken, you can fudge the commands as much as you like so long as you start with 6, have a 2 command, and end with 3B relatively quickly (note: this works for the directional inputs, not face buttons).
Example:
-- This is a normal EWGF in SCV: 6 2 3+B
-- These are examples of how you can kill it, yet still get out an EWGF:
612343243443+B
6623233+B
6329893+B
6098298193+B
etc...
To, RollTide8569:
I also used Kazuya in Tekken but you should know to use PEWGF (f, n, d/f+2), EWGF (f, n, d, d/f+2), and DEWGF (f, f, d, d/f+2). They all have different purposes: PEWGF is best for the second or third hit after launch; EWGF is your standard launcher; and DEWGF link all your combos together so you can wall carry, do more damage, or punish moves because of how much you can lag the ff comand.
For example:
PEWGF x3 doesn't combo
EWGF x3 does
EWGF, DEWGF x4 does
An example of all three versions of EWGF would be:
EWGF, PEWGF, SDEWGF (f~f~d~d/f+2), dash, 2, d/b+2 (B!), DEWGF, DEWGF, DEWGF
So here is an example of the special purpose of PEWGF:
CH d/f+2, PEWGF _ CH f1+2, PEWGF (these are equivalent launchers to a single EWGF)
Frankly, the use of PEWGF is very limited.
