Ex and Why general thread.

From what I've looked up it seems like I need to have a Skrelp/Dragalge with adaptability if I want to actually get a baby with it.
No one seems to be able to confirm Imposter Ditto can give it the HA, and most people are saying it's not true.

Gah, I've been breeding Dragalge with a hidden ability slowpoke and got no results either.
Welp. Does this mean it's impossible to get Hidden Abilities for Pokemon unavailable in Hordes/Safari? Because it sure seems like it.
