Well, a really good TR option is Eruption Camerupt. You're almost guaranteed to go first, and with a 150 BP STAB attack coming off base 105 SpA alongside a 100 BP STAB Earthquake coming from base 100 SpA to bak it up, it is really going to hurt stuff.
You could also use CM Slowbro with just CM/TRoom/Slack Off/Surf or Psychic(I know it sounds stupid, but at least give it a shot) for an excellent tank. Nasty Plot Slowking is even better in some respects.
CB Rhyperior is also a great option, as is Azumarill. With the need for Aqua Jet eliminated, Azumarill becomes even better in Trick Room. Bronzong of course, is pretty much standard on all TR teams.
