Maining Bang I love his command grab that being said. After (If they only emergency tech or * quick get up) 2C knockdown, 5A,2A (delay) you command grab on the ground also for air command grab (same as before quick get up or recovery) a nice reset into the air command grab would be a combo like(you have to be in the corner for this combo) 5A, 5B, 2B, 2C, 623B (Super crash) 5B and then 623B and 5B again by that time your opponent will instantly tech and then you can TK (tiger knee basically input a jump and 623C very quickly example would be bang's D Nails!) command grab in the air! You wanna know more let me know!
P.S. that last one is very hard may take some time in the lab but it feels great when done correctly!
