Phil- Did anyone counter your Crop Rotations on the day? I went down to 1 in my version because I was getting WRECKED in testing if they got countered. I also unwisely excluded Tarmogoyf simply because I didn't want to proxy them. Grrr... What's funny is that you included a lot of tech I thought about but excluded because I didn't test them (Crucible, Consultation and Bitterblossom). That's probably why you went T8 and I went 2-3.

What do you think of a sigleton Dryad Arbor for the Bob Tez match?
The Crop Rotations never got countered, and I had enough Duress effects to see their hand. A bigger problem was just drawing too many Rotations when they wouldn't do anything relevant. I ran out of gas more often than I'd like, and the deck needed more card draw (in hindsight, Ancestral would have maybe been a better splash than Ancient Grudge, heh).
I'm ambivalent on the Crucible... I never played it, and there was never a time I wanted to tutor for it, but it doesn't seem bad on paper.
I'm not sure when I would want Dryad Arbor. The Forest was actually pretty bad sometimes and should maybe just be a second Swamp. I have the singleton Mishra's Factory if I need a creature.
