I think there is a very calcable ultimate or super or whatever its called again for Brawl stars, namely El Primo's ult but I cant get a good video of it, I think it would yield well into 9-B or even 9-A considering El Primo breaks walls with it as well as causing some fractures in the ground, but getting a good video of El Primo ulting into an area that is only walls is pretty much impossible with my setup, but that may be because im looking in the wrong places
