I am the team deckbuilder and ultimately it is my responsibility to verify deck legality before matches happen.
Quite frankly the extension of the round so that it ended in the middle of the Thanksgiving holiday was just downright idiotic, and because of that bad planning I was gone basically the last day -- as was most of our team -- of deckbuilding. I did not verify our decks as usual before the end of the phase was over. It's a shame. Team Entropy seems only to lose based on poor organization or mistakes.
I apologize to ICB who seems to think we owe him one. In fact he should keep quiet and thank his lucky stars that his never-could-beat-us-in-1000-years-deck managed to win because our deck is illegal by a single card, but then again it doesn't change much.
I apologize profusely to our team. We will undoubtedly drop to second place as a result of this "loss" and the loss of vagman which also occurred thanks to no one being around because of Thanksgiving.
