Thanks for answering, as of right now, Calm Mind Mesprit is serving me fairly well. So, what are some common cores in the RU metagame? Surely there must be a Slowking/Tangrwoth core with Regenerator right? Looking at that right now, something like Galvantula could break it apart. Also, what are some superior physical walls? I've seen Steelix, Ryhorn, and Regirock. No leftovers is kinda bugging me on Ryhorn, especially when it has no other recovery, but in reality none of them have recovery. It wouldn't be that bad with Wish, but they all share a Fighting Weakness with Clefable - unless there are other wish passers I am forgetting about. Leafeon maybe? Somewhat outclasses by Tangrowth I guess.
