Not really relevant to the conversation, but I've found MixMence to be more effective this Generation, at least for me. Dragon Dancing just allows the opponent to tease you by switching in and out their Steel-types, preventing you from using Outrage and confining you to Fire Blast and Earthquake, which have a far lower damage roll and will often get your Salamence killed by residual damage and/or misprediction before you can seriously hurt anything. Most people expect a Dragon Dance and switch to something to (p)haze it, only to get a Draco Meteor to the face. And if they then switch to a special wall when it's switched back in again, you can nail them with Outrage. It's pretty effective.
