With Pokemon like Starmie and Metagross, who can only breed with Ditto... Well, the answer is right there. You must always give the Everstone to Ditto, if it is involved in the pair. Regardless of the other Pokemon's gender, be it Male, Female, or None.Ye thanks
But wat about pokemon like Starmie or metagross which have no genders? Do i still give the everstone to ditto and it will work? And how do you catch ditto in poemon platinum... i think its the trophy garden but do you know what percentage it has of appearing?
