The meta for the last few weeks has been Jungo, but I'd imagine there will be quite a lot of GHEIST running this week. SoA might hurt Dregn, and a few other cards but that deck is fairly solid. However, I'd only use Vortex in a half deck, perhaps with some SoA - that should easily see you to the 1300 you want.
Vortex is really strong, and most of the regular t100 players use a deck involving a Vortex half, usually with high damage like Freaks or GHEIST. I would get rid of mono, because the Vortex bonus is basically worthless in the last round.
