Ight here's the secret tech. When your opponent thinks they should block, you use command grab. When your opponent thinks they should jump, use a normal. If they try to use an invincible reversal, then you block and punish.
I really don't have any tech. I don't really lab things unless it's MU purposes or something I seen. I just learn how to use the character then use my amazing reads and neutral game to get my opponent to the corner. If I played a character like Chun or Birdie I'd be ranked 1 on the leaderboards
I did that charged HK v trigger cross up and I taunted when you died from the wall. That's some high level stuff.
My one advice is learn how to space cr.HP so it's plus one so you can get that juicy counter hit st.LP. I think it's that at least most online players don't take the time to recognize.
