...not that im participating in this, but that doesnt mean much since it would still give your opponent a chance to do something, whether set up or spam a stab move. chansey cant do anything offensively to gurdurr or fletchinder, assuming they're at a good amount of health. that gives them plenty of opportunities to set up and prepare for a sweep.
that said, if you're banning eviolite from being used, then i agree on not allowing fletchinder in this, just to make it more balanced and allow more diversity.
