Well I am back from a several-day hiatus ... I did not participate in any aspect of Round 4 ... no deckbuilding, no duelling ... but glad to see that my team finished first (although one of my deck suggestions I made right as I left, that was rejected by the team, would have made us 7-2, grumble grumble) ...
Entropy faces 3 generals this round, and 5 / 9 battles against the top 3 teams besides ourselves. No battles against Underworld. It's going to be tough ... but we're up to the challenge.
Cheers everyone, see you on the battlefield.

EDIT to add:
p.s. I celebrate both Thanksgiving and St. Nick's birthday on December 5th so my vote is for extensions for both holidays!
