So, I was just going through the Toxapex move set question, and thought of an odd way that Toxapex could be broken, if it was allowed. I really don't want to experiment on a Toxapex in-game, I have only one, and don't really want to grind one for an experiment. That's why I'm asking here.
Could a Toxapex switch between Baneful Bunker and Protect every turn? It would be really bad for a regular playthrough, but in a 1v1 battle, that could make Toxapex the winner every time. Is it possible, or is there some weird rule set in place?
