Ok, here are my votes:

1) Art: everything from Joewie Aderes & Decay (count point for Surk's Groundbreaker)
2) Best card: before nerf, I'd say Gilded Organ, but now - Negate
3) Strongest new: Marauding Puddle
4) Domain: Chaos, MF not anymore...
5) New: CI can't stand a chance against chaos. (unless it's really good psion deck)
6) hard to choose one, but Soul Plague (game breaker), Ord Stone, Overlock, Marauding Puddle once again
10) Weakest: Psychic parasite (Just won't pay itself back.) Oh.. and Zeppelin Raiders.
