Not really. When you pick two Pokemon you want to use as partners in doubles, you generally want to select two Pokemon that share a diverse array of resistances (especially to spread attacks) and that can hit a wide variety of targets between their attacks. Classic examples include Garchomp + Zapdos, Metagross + Rotom-W, and Hitmontop + Latios. Slowbro and Slowking get near identical coverage and share the exact same array of weaknesses. All it takes is a Pokemon with Discharge to bring them to their knees.
My interesting bit was in the haha fun interesting not serious but point taken.
Who would make a good Partner(s) to Slowbro/Slowking, Arcanine, and Emboar?
Are there any strategies that are used that aren't Trick Room, Weather, or Gravity?
