I AM THE JAMAICAN BOBSLED TEAM
formerly Smog Frog
So I've been using CB Entei+SD Mega Pinsir. It's like double dragon but its not double dragon. Basically, wear down checks, and clean with one or the other. Latias is a great complement to this core, being able to Defog and use Healing Wish to heal up so one of the guys clean the worn down opposing team. Also, the powerful priority between the two allows for revenge killing and stuff. Just be sure to keep rocks off the field.
