what? you can't take what I say and try to get the counter point used. I was saying Tyranitar was the exception, not the norm. Abomasnow, Kyogre, Hippowdon, and Groudon (to a lesser extent than the others) all use their ability to influence their playstyle (they're in greatest-->least order of who uses it most). Abomasnow is used solely for Hail. Kyogre be a much smaller threat if it didn't have double-STAB Surf/Hydro Pump/Water Spout. Hippowdon uses Sandstream to help it stall stuff to death. Groudon uses Sun in the most general sense, either to remove Kyogre's rain or to boost the uncommon Fire moves on it. This Pokemon would be somewhere around Kyogre on how much weather influences it.Agreeing with Hyra in a way, Tar would often prefer no Sandstream and I think in the case of this pokemon too Sun is definitly a double edged sword.
TTar doesn't fit in with the rest, because he doesn't really care about the 1.5x SDef boost most of the time. The boost and damage from Sand help him, but aren't essential to his strategy.
