I got a question: Would Jellicent happen to slip to RU? If it does I don't know about CroCune now that I think about it. Yanmega would definitely be threatening. Even with common threats in UU last gen in Raikou and Zapdos, Yanmega was still able to pull through and still does what it does best at late game sweeping. Yanmega is also a Pokemon that can do well in RU now that I think about it.
