I'm surprised CroCune isn't getting more attention. I started using him, and it's absurdly easy to stall just about any offensive threat. His spd bulk from calm mind coupled with scald make it almost impossible to do any better a 3HKO on him. Not to mention, what seems like a very "Prankster status inducer" heavy metagame, the ability to rest away status makes him a great switch in to Klefki, Sableye, etc. Then, because they can't do much to hurt him, just set up with 2-3 calm minds and RestTalk your way to victory/ragequit.
