I get all tingly inside when nonAmericans share the love of bacon <| sep |> I ' m not sold on Dak . he leaves a lot of points and yards on the board . This will get better with time , but as of now , I think he just has an incredible supportig cast . <| sep |> Gigalith is okay . It can do fine as a Rocker and in this gen it actually got a buff because it got a new ability in Sand Stream so it can set Sand for its teammates . If you ' re playing OU , you ' d honestly be outclassed by Tyranitar as it does Gigalith ' s job entirely better . You can always use a team of mixed tiers , but keep in mind that the Pokemon with the highest tiering is the tier you ' ll be forced to play in . So if you bring a bunch of NU Pokemon into Ubers , you ' re going to have a rough time . You can bring any low tiered Pokemon into a higher tier , but not the other way around .
