>>31865304Add in a Marowak and a Tapu Bulu, Bulu because Grassy Terrain will weaken the power of EQ on your Pokemon, which is always good since you have a Marowak and Muk. Speaking of, I prefer running Iapapa berry on him with Gluttony. I found that it helped me in close situations more than the slight recovery from Black Sludge.
Marowak is there for the raw power, and because it does very well in Trick Room and it can also work as a nice thunderbolt sponge since you do have a Slowbro.
