That's what I will always do. I don't often battle players from across the ocean. XD My friends have DS and pokemon, and I'm satisfied with that. Since this team will (and almost always)flatten them.
Empoleon Sp.A and Sp Def
Milotic Sp.A and Def
Metagross Atk. and Speed
Regice Def and Sp.A
Latios Sp.A and Spd.
Lucario Atk and Spd
Mostly my team are tanks, and sometimes I use Dusknoir at start with Trick Room, which can certainly disable speed freak dragons.
TOO popular in fact, that people often tend to misuse them. And Tyranitar can certainly kill chomp and mence with the right moves and luck.
