Coba/HP-Rock Keldeo
HP Rock Keldeo to counter all your Mega Pinsir problems, it is ev'd to live a +2 quick attack from Mega Pinsir with Coba berry. The 236+ is enough to outspeed max speed Jolly so you dont have to worry about return. I also used this mon in PFA to help me advance to the semi finals!
Agility/WP Metagross
One of my personal favorite set to use, Agility Weakness Policy Metagross. With +2 Speed metagross outspeeds a majority of threats such as Landorus and Garchomp. With Clean Body Intimidate isnt an issue and its steel/psychic type is great offensive and defensive pressure and it has enough natural bulk to live Earthquakes from said mons. Knock Off isnt a problem because of Weakness Policy.
Specs Serene Grace Blissey
Finally my favorite set ever probably. Specs Blissey is just plain fun. Abusing Serene Grace with Bolt/Beam as well as Flamethrower helps for maximum coverage. Its natural bulk lets it take special attacks like a champion and Healing wish to heal up other mons around it.
