I would like to ask about the ability change in DPPt. As we all know some Pokémon only had one ability in Generation III. However, they gained a second ability in Generation IV (for example, Scizor, Breloom and Clefable). I read these Pokémons' ability may change while evolving in Generation IV if the Pokémon was migrated from a Generation III game. So is it already decided (like Hidden Power, IV's etc are) if the Pokémon's ability may change, or does it change at random every time you evolve it? If if happens at random, I may try to soft reset to get a Magic Guard Clefable. If it's already decided whether the ability changes or not, I would just have to breed it on Platinum. (I really prefer to breed in Emerald, since Pokémon hatch at Lv 5 instead of Lv 1 and the cloning is possible in Emerald, which is nice if you would like to make two different sets for that Pokémon)
