A few personal suggestions for Mienfoo's analysis:
1) For the bulky attacker/pivot set, I feel like in this meta, Slow foo is better and more popular than 17 speed foo. I would move it to the main set, but it isn't that important.
2) For the slow pivot foo, instead of the recommended 156 HP / 116 Def / 196 SpD with an Impish nature spread, I would suggest a spread of 76 HP / 196 Def / 196 SpD with an Impish nature. Even though this overshoots the Eviolite number, I find that this tweak is more appropriate for this meta. The additional point in defense allows foo to almost always (93.7%) survive a Brave Bird from max attack Vullaby after Stealth Rock, while still almost always surviving Focus Sash Abra's Psychic after Stealth Rock. Then, Mienfoo no longer has to worry about a Vullaby switch-in on his Knock Off, since it can tank a Brave Bird and KO Vullaby with HJK after a Weak Armor Defense drop. The additional Defense investment also allows Mienfoo to have a small but non-negligible chance (25%) to survive Doduo's Brave Bird after Stealth Rock and Zigzagoon's Extremespeed at +6.
Downsides of the change: due to the loss of 1 HP, foo now has a 50% chance to die to Shatter Psyche from Carvanha. Also, all the calcs get messed up by Spikes, but with Vullaby everywhere, Rocks should be much more common. A hazard removal is still useful for Spikes I guess. I think that the advantages are worth this little downside, since otherwise, the 1 HP doesn't matter as much, for all the options that I've considered.
