I agree that Sableye should be added to the list somewhere. C tier sounds like a fair place to start. (I want to argue for higher but I'm pretty biased towards this guy)
(Going to respond to this since I think it was directed at me :P) I do agree that the best reason to use Reshiram is to abuse sun boosted Blue Flare, whoever it's not weather dependent that you can't excuse it's use elsewhere. It would only really be in niche circumstances (Roasting Ferro under rain/ reliable STAB under Sun/ punished less for predicting a Steel switch-in) but it was just a point brought up to show that although it should only be seriously considered on a Sun team, it isn't completely dependent on Sun to be threatening.
Also Sun Blue Fire is literally the only reason to use Reshiram (except for Flame Charge I guess but who the hell uses that). If you're trying to use it anywhere but a Sun team you are far better serviced by Kyurem-W or Rayquaza.
