messing around with frkz mixups, crossup dash + 6a seems to work REALLY well, ive got it to hit everytime so far, although its netplay so lol.
you can chain 6a into 2c into kaerus frkz combo since 6a is only 80 p1, and does 5.4k in the long run with the web nail + dfk ender
reason im using 6a is because its somewhat fast, is cancelable into 2c, dash cancelable(so it makes it faster than a crossup 5b/2b), and leads into decent damage
