This thing is bulky on both sides of the spectrum, and it's surprisingly a pretty good attacker too, taking large chunks of health out of specially weak Pokemon. I might try and fit one of these bulky mushrooms into my team. Spore is a godsend, especially when there's a Pokemon that's destroying your team, and Amoonguss can survive a hit from it, Spore it, and it's usually incapacitated for the remainder of the match. Black Sludge as an item might be able to work too, but there's always the chance of getting it Tricked to one of your healthy Pokes and screwing with it, while taking your Lefties or Eviolite or what have you. The only problem is that its' movepool is pretty shallow, but it gets Toxic and Spore, which are two excellent status-inducing moves. It also gets Rage Powder, but I have no idea what the hell that's all about, and it sounds like a waste of a move slot unless in doubles, and even then, it still sounds like a waste.
