I just found out it's currently unobtainable since Skrelp isn't in friend Safari yet, and apparently you can't find a HA Skrelp in the wild...xD
But to be honest I just wanted it shiny. :T
Ah well, I got a shiny one from a friend so I stopped and just Wonder Traded all the rest. xD
It's just that, apart from a few Poison and Steel pokémon, I don't know many that I like and I really don't want Fairy friends to beat me too easy. Dragalge proved himself quite useful against them so I'm happy xD
