Easiest way, I think, is to custom search for ranked Swarm games on this map. Swarm gives the highest chance of you being on the winning team, and searching for a game will prevent you from being matched in a party without the DLC. Do a search, if there isn't a game, do something else. later, search again.
There's not much more you can do.
EDIT: Swarm is now the only way to get this achievement. VS. Ranked Servers have been closed.
