A DMH deck I played in a 6-player multiplayer last weekend in Hartlepool. I ended up coming second.
As with all DMH decks, cycle the DMH cards out of your hand as quick as you can, and don't play the J deeds.
I managed to pull a few DMHs during the game, and also a few that were one card off but someone cheated, so I was able to use Pair of Six-Shooters to change my hand. Also one vicious Quickdraw Handgun when that turned out better for me than the six-shooters, trading a 5OAK for my 3OAK hand.
Game went to time (we had set a limit of six hours) and I didn't have as much control + influence as the winner.
