Using this list (and a slightly different version of it), I've done the event twice -
Run 1: 6W1L (lost to a clockroach deck that got killer right off the bat and made a bazillion roaches)
Run 2: 6W1L (lost to a misplay - could have given my Hero of the People overwhelm for unavoidable lethal, but missed it).
The deck is VERY good - it just runs people over, occaisionally drawing a concede as early as turn 2.
