I've been out of the country for a family issue, but I have had my laptop and been able to do a little bit of testing. Here's what I know so far:
Tezzeret is really freaking hard to play! For a million dollars, if I had to correctly cast Gifts Ungiven, I wouldn't be able to do it. Heck, for $100 if I had to split Gifts Ungiven correctly, I wouldn't be able to do it. Trinket Mage and the Transmute cards are also really hard to play because you can get so many things, and depending your list, if you misuse one of your tutor targets, you're screwed for the game. My plan is to proxy the deck up and just goldfish it tons to see what the plays are, without the pressure of real game situations.
Other than that, it seems like Rubin Zoo is the deck to beat, and I'm leaning toward something that outraces it. Probably not Steppe Lynx Zoo since that version of Zoo actually makes Punishing Fire pretty good, but more like the bogeyman from two years ago: Dredge. Tuning that deck will come to guessing how much hate people will be packing in their maindeck and adjusting the Dredge maindeck appropriately. For example, I think I want Darkblast to have some kind of answer to Gaddock Teeg. If I think people will be packing Ravenous Traps and Leylines, however, maybe I'd be better off playing Rubin Zoo or Tezzeret.
I also haven't touched sideboards yet. It seems that you can tune your sideboard to beat any deck in the format. Again, comes down to guessing what the metagame will be and what other adjustments decks will be making between now and the first PTQ (which happens to be Seattle this season!)
Still plugging along...
