But goodstuffs is by definition pretty much uncounterable, so you might be better off trying to identify the specific Pokémon/types/whatever that tend to give you trouble, and adjust your team to deal with those.
goodstuff, especially bulky goodstuff is very hard to counter. I run 1 too, but even I cant find any glaring weakness. It just depends on the matchup. Like to me the only thing I lost to is having a bad lead matchup, or hax, or other bulky goodstuff teams.
