Been experimenting with un-upped decks for PvP 1 lately and gave this a shot... it worked out surprisingly well.

Basically, you fire off a couple Novas to put out a Devourer and Rustler, then use those and your Mark to put out the super-buffed Vampires. Fog Shields are sprinkled in there as great low-cost defensive; while their creatures miss, you can catch up a lot of health.
The # of Novas in your opening hand is critical...
>= 2 Novas: good stuff
1 Nova: slow start, hang around a few turns and hope for the second
No Novas: gg, rage quit
