It can hit Vaporeon back with Toxic, as well as a lot of other bulky waters. The only problem with Bulky Waters that I've run into is Restalk Crocune. Thunderpunch and HP Grass are there too if you're worried about those.

This isn't meant to be the most used set, nor the best defensive set, but it has really helped end sweeps for me. The already bulky defenses, plus boosts, along with unaware, can stop most sweepers cold. The problems that you guys have mentioned are primarily with either support or other defensive Pokemon, as well as gimmicks, and those are definitely not the sweepers that Stockpile Arghonaut helps to keep in check.
