better run both dual chop and iron head, quitting outrage and dragon claw
giving a fairy type 2 free turns (the turn the rampage ends by the immunity, the turn you switch) after you kill something with it seems scary (imagine face a +4 mega mawille), and dual chop has exact the same base power as dragon claw (error, sorry), and earthquake out damages dragon claw, being the safe move of choice anyway, while dual chop breaks through substitutes and sashes (hi gliscor). iron head is better than poison jab as it lands a crippling blow to steel types without having to rely on the shaky accuracy of stone edge. you should also consider switching the same stone edge for fire blast/fang to roast skarmory and ferrothorn on the switch
