Toxapex's Baneful Bunker + Protect?

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?

Using Protect, Detect, Endure, Spiky Shield, King’s Shield, Baneful Bunker, Wide Guard, or Quick Guard consecutively decreases the chance of success of Protect, Detect, Endure, Spiky Shield, King’s Shield, and Baneful Bunker for each consecutive use.http://bulbapedia.bulbagarden.net/wiki/Baneful_Bunker

Although it doesn’t say how much it will decrease the answer is most likely the same with the other moves, being 50%

EffectsProtect prevents any attacks targeted at the user from striking on that turn. It is identical to Detect.Its accuracy drops to 50% if used consecutively after itself, Detect, Endure, Quick Guard or Wide Guard.https://pokemondb.net/move/protect
