First off I feel it right to tell you that, that is an awful move combo and that Hammer arm is a much better choice than Super-power in this case but I will tell you how anyway. Emboar being in the feild egg group is capable of having any egg move on him easily because of a little thing called Smeargle
- have Smeargle(Must be male) sketch Curse then relearn Sketch(from the move re-learner) then Sketch Super-power this is easiest done in a double battle.
- Then get a Female Emboar(you can breed a male with ditto until you get a female if you do not have one)
- then you put them both in the day care and wait for an egg.
When you get the egg hatch it by walk/run/biking around and when it hatches it should know both of those moves.
