I am with this in principle. I.e. if we could say for certain that we could easily ban any use of battle helpers in the modern format, I'd happily vote yes to that 100%.

I am however a little concerned that while this would stop the majority of people from using them there would likely be a few that still had access to such a service and so be part of an exclusive club which would be at an distinct advantage over the rest of playerbase.

Also not sure exactly how this can be enforced?
