Wolf's is 9f, meaning he can use it get a free punish attempt on -9 moves, and also a free attempt off of a guarded near the wall. While I don't think its overly powerful, I do see it as being an important tool for Wolf's game. I don't know every -9 move, but I'd imagine it's better in some matchups than others. When used Goh will not be able to use his throw reversal from his -10 moves like , , or . So, once the opponent has to respect , it'll make his other options more viable, such as , which can be deadly.
