Okay you put in a link trying to show that you can breed an Emolga with a Ditto to get an Emolga with Iron Tail, which you can't. If you would check your own link nowhere on any of the lists for eggmoves is Ditto a compatible partner for breeding the move Iron Tail into an Emolga. The only move Ditto can ever know is transform and it only has other attacks after transforming into the opposing pokemon. Smeargle would be a better choice since it has the move Sketch which, after using it, allows Smeargle to learn any attack.
