Well, let's see. Lustrous Orb Palkia w/ Fire Blast is probably your best bet. SpecsOgre, Arceus-Ghost, Substitute Darkrai, and Shaymin-S also work pretty well, although Shaymin needs to watch out for Gyro Ball. While unorthodox, you could also simply trap it with Magnezone. If you just want to minimize its impact, Forretress walls it and sets up.
