Well if you're only casually involved with the tourney scene...do you need to keep up with the current Standard trends? I mean, with the decks that relied on Mystic/Jace neutered, you should feel free to play whatever you want, no? No need to worry about who the big dogs are...I guess unless you're thinking about sideboards.
In which case, expect to see plenty of Valakut and Vampires, and plenty of other aggro. You may see some control, infect, and Tezz builds, but they won't do as well given the undefined nature of the format. I'd stick with something aggro like RDWs for now.
