If it applies to all late game sweepers, then why is Ninetales so special?Keep in mind also, that those pokemon may be hurt while battling, but you can just save Ninetales (as all the late game sweepers) until they're weak, so you can own them all)
I don't deny that Ninetales can be a good late game sweeper, but I wasn't arguing that point. I was challenging your claim that that Ninetales set can't be walled, and I have subsequently shown that it can.
Though if you ask me, I've never been overly keen on the idea of Ninetales as a late game sweeper. I prefer my late game sweepers to be less prone to revenge killing.
