>>20852530Breeding with a 3IV foreign Ditto is probably a bad idea since there's a strong chance of the offspring getting the bad IVs.
If you ask in the Genning general or the Trading one there should be someone able to give you a hacked 6IV foreign Ditto, those are the typical sex-slaves of the thread. If you don't want to or can't, most people breed until they get the Hexaflawless seven and then use those in lieu of a Ditto. But unless you can acquire foreign ones or a foreign mother, MMing won't work with them for obvious reasons.
