Well, the Acrobatics thing is mostly because the Flying Gem isn't legal yet. Course, you've got your gimmicks like the Liechi Berry etc, but hey. It's probably worth more mentions.
Best used as a Lure for Mega Diancie but worth a mention now. Currently in the metagame, these are the moves generally used now. I ordered them according to importance rn. I would also say that spread aside some sets just 248 HP / 252 SDef / 8 Spe or something like 242 HP / 228 SDef / 60 Spe to get a wisp on max Exca or 248 HP / 160 SDef / 100 Spe to get a wisp on chomp and base 90s maxed like Lucario. That said I don't if these are the most optimum spreads so take it with a grain of salt. I think Bulky Volcanion is a check but people probably use it. Do some researching, I'll be doing it too! Till then.
