I don't know if anyone has talked about SpDef Bronzong, but I think its really good in the current meta as one of the best answers to a wide variety of threats such as Rhyperior, Shaymin, Mega Abomasnow, and Kyurem (however, subroost can stall it out of gyro balls). It can also take on Exploud's Boomburst, something not very many other Pokemon can boast (although you have to watch out for a Specs Fire Blast). It is a very reliable Stealth Rock setter, and finds plenty of opportunities throughout the match to set them up. As well, it is no slouch offensively, as it's STAB Gyro Ball always has a very high base power thanks to its base 33 speed, and base 89 attack is decent. As well, it can run Earthquake to hurt fire types like Delphox hard on the switch. However, Protect is a good option over it for getting lefties recovery, racking up toxic damage, and scouting out choiced attackers. I've tried out both Hypnosis and Toxic, and I think Toxic is a lot better; Hypnosis is too inaccurate, and it's very nice to hit something like Moltres or Gastro with a Toxic on the switch. If you want a sleep inducer, there are heaps of better options, like Tangrowth, Vivillon, and Amoonguss. Some people are running Heatproof, to allow it to better take on things like Delphox, Exploud and Azelf, however this means it can't take on Shaymin, Kyurem, and ground types like Rhyperior and Dugtrio, which are more threatening imo. However, if your team already has good answers to these, Heatproof could be a good option. Bronzong can do a lot more than this though, it has access to Trick Room and dual screens if that's more your thing. Bronzong does suffer from a lack of recovery, so it should be paired with a Wish passer. I'd recommend Aromatisse as it has good type synergy with Zong, but there are plenty of good options. Bronzong unfortunately has issues with slower, bulkier Pokemon, but many of them are susceptible to Toxic. Overall, I've found Bronzong to be a very effective pivot and Stealth Rock setter for balanced and defensive teams alike, and is definitely one of the best Pokemon in RU right now.
