Seriously, no Serene Grace? Burns weakened half of the things on the threat list, like Azumarill, Mawile, the Ground types (if we're faster), and the physical aspect of aegislash, to say the least. Anyway, voting reasoning:
Analytic: It's the best one we nominated for providing offensive pressure against the foe for supporting the core.
Regenerator: Extra health is always useful, especially when this Pokemon also has to serve in a Pivot role.
Contrary: It may be a little overspecialized in the way it was discussed, but it can have potential with Overheat (probably) and/or against King's Shield.
Bulletproof: Left off because of reasons.
