No hax in a fighting game!
Also, just so you know, if you've got a character doing a move that is hitting right at the exact moment you get up, almost every move will fail. Even really fast moves have one or two frames of start up.
For a character like revenankh, if you suspect someone like Soil will be pursuiting right as you get up, there's one move you can do! Shadow punch. Shadow punch is invulnerable on the very first frame, and other moves have this property too. Cut for Argh, possibly fury swipes for Ant, and there are others I don't know. The catch is, if you don't time it perfectly you get hit. Worse still, the moves usually have some lag afterwards if you miss.
All in all, best strategy is to block until you've got an opening. Moves like pursuit have a little lag after to give you breathing space.
And sadly, yes, it's true. Beating the AI in a fighting game is mostly just abusing AI. Making fighting game AI anywhere near like playing a human is hard.
