With a choice scarf it can't make use of swords dance, so if you're going for that then replace sd with another move. Rock, ground and steel is already perfect neutral coverage, so X-Scissor, Poison Jab, Shadow Claw and Brick Break are all valid options depending on what you want it to be able to hit. Since those four are already available TM moves you can shift between them depending on what is more convenient for the situation.
