Pin missile seems like a good idea, for obvious reasons. Submission seems good too: Doug said that Voodoom fights underhandedly with voodoo as its fighting method, so Submission, which gets STAB and produces recoil (sticking itself with a pin,) could also have interesting effects and fits right in with Doug's description of why Voodoom gets its Fighting-type. Double-Edge, movepool requirements or not, is worth a look. Heck, ANY recoil goes well with a voodoo Pokemon. And lastly, Voodoom should get Destiny Bond. Unless it's outright decided Voodoom is better without it.
