For your team, Conkleddur would be way better than Scrafty because of full power and absolutely, as it's ability says, sheer force. With Conkleddur's moveset you can't go wrong; but you use earthquake, a good attack, too much and with that other trainers can easily predict your team. A good moveset would be:
Payback - You'll see whats coming up + Psychic type coverage.
Hammer Arm - Combined with Payback, this is one of the best revenge-killers ever.
Stone Edge - Raw power. Any questions?
Mach Punch - It may seem useless when you have Hammer Arm, but you can really surprise with this thing.
If you want, you can add in Bulk Up, but this is a fine moveset.
PS- You better stick with leftovers because you don't want Conkleddur down early.
