Swords Dance is an ok option, it does very well against slower teams actually, like:
+2 252 Atk Tough Claws Mega Charizard X Flare Blitz vs. 252 HP / 252+ Def Hippowdon: 327-385 (77.8 - 91.6%) -- 75% chance to OHKO after Stealth Rock and 1 layer of Spikes
It can OHKO one of the best Physical walls in the game, with a neutral nature. And how does Dragon Dance take too long? It takes just as long to set up two Dragon Dances as a Substitute + Swords Dance, and most of the time you won't have the Substitute effect, as they'll bring in a check / counter and will break your sub, so.
