If you could help me with a few questions though, I would be grateful too: A female DW-ability pokemon breeding with a Ditto will NOT transfer the DW ability, is that correct? So I would have to breed a male poliwag with that perfect ditto, then breed a good male offspring of theirs with the DW Poliwag in order to keep the ability?
Yes, I have a perfect Modest ditto on hand. The conditions attached to the ditto when I got it were that it was a fully redistributable, basically charity ditto, so if anything I should be giving it to you for free! So if there's anything in addition to that that you want, just say so.
