I know this research week is almost over but there are a few things id like to say about Throh.
With its massive base 120 HP and 85 defenses, Throh is the bulkiest fighting type in the game. It can perform multiple roles in such as Bulky attacker or Shuffler. After testing during this research week, this has been my favorite Throh set:

Throh @ Leftovers
Trait: Guts
Evs: 252 Hp / 4 Atk / 252 SpDef
Careful Nature
-Rest
-Sleep Talk
-Circle Throw
-Payback
This set is great on a Hazard Shuffling team, being extremely bulky and able to semi-reliably recover health. Throh received Sleep Talk from BW2 so he can actually do something when hes asleep and doesnt have to rely on the one time use Chesto Berry. Guts makes it so status really isnt that big of deal granting him an attack boost, while he can just use rest once his health gets low. While it does have to give up Bulk Up for Sleep Talk, it can recover much more reliably. Circle Throw is needed to phaze opponents out and is the sole reason for this set. Payback is so its not completely walled by Ghost types. Spikes support is obvious so I chose Cacturne who offers decent synergy, although sharing a flying weakness. This set is incredibly bulky and extremely had to take down with a super effective move on the opponents side, making it great special wall and shuffler.
