Ok, Ok, lets hold on a minute. I agree about the Shuckle statement made by Richard Steel, so we are going to get rid of it. Plain Split is a good idea, so we get rid of Curse, and put that in. Claydol has high defense, but he also has six weakness:
Water
Grass
Ice
Bug
Ghost
Dark
I am afarid that is a few to many.
I will remove Probopass because it to has poor HP, and i will put in Skarmory. I will also add Spiritomb, but there probably is a pokemon with better defense.
