That could be sick i could see them doin something like other chatecters as back ups on attacks so you can have like a teamup deck like you could have an attack that has like sero on it that builds into a sero backup could be fun
Maaan this theory is so neat i love it! this idea has such legs and if OFA quirks do get cards i hella want something like this for AFO, maybe an evolution of the current Impact Recoil card with a shift like how it builds down on block!
