You know, given the fact that the customization is just each B move having three different variations, there might be a chance that it wouldn't be banned.
The only things I could think of that would prevent it would be if some variations were extremely OP, (although I'm sure individual variations could be banned I guess if it would be a problem) or the fact that Dittos could be a problem
