This team is pretty self explanatory. Mostly stolen from RU sample thread. Only change is Exploud. You want to set up trick room with Reuniculus and have Exploud do damage while trick room is up. If you find that doesn't work well, feel free to change the evs for exploud and remove trick room from Reun and replace it with calm mind or something.
