This deck is quite similar to my previous deck
Even Hour, but with a few strong odd cards in place of the Evenhanded Golem/Scream/Last Chance engine. I considered this already before the Tasbu buff, but it's a lot more attractive now. I think this is somewhat stronger than the even version and it was the sole deck I used this month to make master, though it is probably still not top tier.
A couple notes:
1) You want to Ice Bolt your own unit a lot in this deck. I haven't been keeping count, but it wouldn't surprise me if I use it on my own unit more than half the time. Slumbering Stone into Ice Bolt lets you play Vara or Honor on T3 (or two 2-cost cards). Tend the Flock into Ice Bolt isn't as good, but still playing Tasbu on T4 can be pretty nice, or making sure you have 4 power on T4.
2) Don't forget that you can kill your own units while Tasbu is out to draw cards. Snowballing or Favoring your own sheep on the same turn you play Tasbu is a common (and strong) play.
