Welcome to Smogon! Take a moment to read the Introduction to Smogon for a run-down on everything Smogon, and make sure you take some time to read the global rules.
Aromatisse and Cofagrigus are both good TR setters that would work somewhat better than Reuniclus. Though I use each in different roles overall, when I use either they're mostly there for support rather than attacking.
