Also you can use Ex Tatsu to Safe Jump Balrog. Because Ex Tatsu hits 3 times, you can safe jump attack and you don’t have to worry about delay standing. As far as Block Strings try: crLp, crLp, crLk. If Balrog try a Head Butt reversal or end his Charge Attack with Forward, instead of down + forward, Balrog will get hit by the crLk. Also I found that Far stLk and Far stHk can hit a crouching Balrog to help lock him down.
I use it in matchups where it lets you punish otherwise unpunishable moves, like Poison and Balrog. I pick it against Bison too due to EX Run through Scissors, but that’s a hard read.
I can’t make my mind on whether I should use U2 or W-Ultra though.
i definitely would use W ultra against a really active Bison just because you can punish his devils reverse with ultra 1 just as a deterrent, if they know, and if they dont then you get the punish.
