So now that ORAS is less than a week off and with it a bunch of new Megas and tutor moves for genVI pokes. What is your final XY team?

Still primarily a doubles team, and after testing the new megas/tutors all that likely to change in ORAS is Helping Hand on Aromatisse and maybe white herb/Ice punch on Hariyama

For me it has to be my Shedinja Team, that took 3 Gens to perfect. It may not be perfect, and seem a little Gimmicky, but it worked realy well.
