My favorite is stacking, and I think Fighting-types are the way to go right now (SR resistance, hitting all Steels at least neutrally) IMO there are too many Steels for Dragon stacking. It's doable, but I don't have the patience to play around resists. Take a combination (usually 2) of the following: DD Scrafty, Double Dance Terrakion, SD Mienshao, or SD Lucario and send them through. Then, bring in Deoxys-S LO 3-4 attacks (Psycho Boost definitely, OHkOes Rotom, Gliscor, Haxorus). A Scarfer is nice, and there's always Wobb for opposing ones. Speaking of Wobb, Jolly is awesome. I prefer Safeguard so I can encore and set up, but Tickle+Pursuit is really effective in taking out some walls. Finally, special sweepers can kill without Blissey around.
