I'm aware the main answer may be 'use a Ditto' thus transferring forward from the older games. Fun, fun. But I was wondering if there were any other ways to get a Sawk Egg other than the universal pokemon?
Sadly, no. when you breed a male and a female, the pokemon comes out as the females pre-evolution, and since all sawk's are males, you will not be able to breed a sawk without a ditto.
