>>32913012This got me thinking.
If mew and smeargle can both use transform, shouldn't they be able to breed with any pokemon, similar to how ditto does it?
Mew being unable to breed is most likely just gameplay/lore segregation, so I'll let that slide.
But that still doesn't answer why smeargle can't breed with all pokemon.
Im starting to think egg groups might just be bullshit.
