I decided to try this team, and it is pretty great. I have played I am 8-2 right now and with a rating of 1555, and the only reason i lost two was from a poke that could stall me out because i was being to reckless. I don't see too many problems really, I have just been losing keldeo and latios too fast and getting stalled by a forretress because of it, but that is my fault.
The MVP of this team right now is stuck between latias and keldeo, as they both do great. No one really expects the draco meteor on latias because it is usually dragon pulse, so i usually get a nice kill that will allow me to sweep with terrakoin. On the other hand, Keldeo completely destroys politoed to help me win the weather battle. I love them both, they are super helpful, though it is sometimes hard to keep latias alive from life orb damage and sandstorm damage. Gliscor is pretty nice too since i can sometimes get up a sub and baton pass. overall, this team is just great.
I will try to post more after some more battles, probally will try to ladder higher, try to break the top 100
