Shadows of Solitude
I could try to farm a sableye for you if you wish?
It might take a little time but I'm willing to currently I don't have a foreign origin sableye so I'm not able to breed for prankster at this moment.
I also have a japanese female sableye with prankster and max def/sp. atk IVs if you want it.
That is, in addition to the 'murican bred prankster sableye I currently have for the original poster, which has max HP/def/sp.atk/sp.def IVs and a calm nature. Also knows recover, which the japanese one does not
