The strategy here is to setup a negate board while setting up the DM/Circle/Nav combo. Best negate board is Appollousa, Norito, and Right Hand. Its not much but this is the closest thing to a pure DM combo deck. I played this deck against Strikers and Shaddoll/Invoked so far, and it is very competitive worthy. Long live DM!
