I was so ready for Scrafty and Toxicroak. I was going to make a team and everything!
Anyways, Scrafty in OU is a bit underwhelming. Its amazing type coverage and can take some damage at times, but it is basically walled by skarmory and other bulky pokes, not to mention that its only recovery is in the form of Rest, which is pretty bad (even with shed skin). I like this guy, but I think he could do some serious damage in UU.
At least, that's what I've seen. I bet in a good niche he could sweep, wall, or whatever well.
