implying that auto-Sand isn't already in UU >_>
I don't disagree that Hippo would probably be a monster in UU (I've played very little UU, but...). However, I will absolutely rofl if you think it's the auto-Sand that would make it broken.
I know that sand is in UU already. On hippopatos. And he isn't very good, only as a physical wall really, and ss teams arent bastardizing the UU meta like weather in OU. Hippowdon would change that, because he is too good for UU, I have high expectancies that ss teams could become centralizing to UU if hippowdon stays for a while. As of now, hippopatos for ss teams is nice, because there aren't a lot of them in UU as far as I'm concerned, and so it becomes a small niche team that adds to variety, like trick room.
Steel Pokemon are boss. Metagross is the real steel.
