I don't think usage alone is ban-worthy, especially when you're talking about 1337 stats. Maybe Tyranitar is there because it's a /better/ Sand Stream user then Hippowdon, and that sand is simply a good strategy itself. Nothing about it stands out as inherently broken: it has no recovery, 4x Fighting weakness, little Speed, etc. I think it's sand raising TTar, not TTar raising sand.
