It's impossible to legitimately obtain an HA Arorus, Tyrunt or Skrelp right now, as those Pokemon aren't found in any Friend Safari or Horde (which are the only ways you can get HA mons in X and Y). How do you think GameFreak will release them?
Somehow, I can't see them being Event releases. Maybe the fossils, but not Skrelp. I fear we may have to wait for Pokemon Z, which'll have new areas or something, to be able to get the unreleased HAs.
