Excellent post and deck! I'm running Sage of Renewal this weekend, too, but I stretched my mid-range deck a bit rather than go full control. I did pick up vines and ritual though. Surprisingly cheap cards. The best thing about the nature control deck: you don't need Demogorgons. Sage is arguably just as good (or only slightly worse). Pulling an Arrow of Rage and taking out a Guild Enforcer or something feels great.

One question about Hive SBI: I should have about 6-7 if I've kept track from winning several (thank you!). However, my balance shows zero. Could you check to see if they are distributing correctly?
