Seeing as this line learns Absorb, I would have to assume Goodra can learn Giga Drain via breeding, which would be a pretty good addition to a lot of offensive, defensive, and tanky sets. Only problem is, nothing it can mate with currently can learn Giga Drain. Seems like Goodra would be much more viable in a defensive role if it could get access to some sort of recovery. We'll have to wait until Sceptile becomes available via the bank in december to see.
I'm going to keep testing egg moves. Next on my list is trying to find ways to breed on Recover, Moonlight, Morning Sun, or Pain Split. I've already deconfirmed Synthesis.
