Mark Harrigan for backing up one seeker on duo

This is the deck I came up with for playing with seeker duo with my wife. I'm open for critics, it will be my first time playing Mark.

The strategy is rush for Guard dog/ True grit to soak damage early on and draw more cards giving more space for other actions other than drawing.

The upgrade I was aiming for upgraded Beat Cop, Guard Dog, Vicious Blow and Dodge first, still thinking if it was worth some healing, or to just leave that for the Seeker.

Any help will be welcome.
