Welcome back ConnerMcManus!! Sorry to hear about your serious girlfriend.

In short, the deck to beat right now is Grim Tutor.dec. With portal legal, this card has exploded. Various builds run Misdirection over Duress, both with great success. 5cStax is a natural answer, but has to fight through Drain infested waters, namely Slaver and Gifts Ungiven decks. 'SS' is a fish style UB deck that doesn't run Null Rod, but is dangerous and creates a nasty lock on you. Squeeless-Dragon, Salvagers and Oath are all notable decks. Even a new RG deck just won a major event. I'm sure I'm missing tons of things. Check out StarCityGames tournament result decklists Top 8s for more info.
If you are going to Gencon you really need to watch out for 'Grim Long' and 'Pitch Long' as they will be played to the top tables by all the name teams, for sure. Watch out for tricky sideboarding strategy as well.
