Last year we had a team name - mailmen - and a slogan - we always deliver.

How about something like "Team BlackJack - Buck or Bust! No Surrender!"

- ala the BJ term bust meaning to lose, or going over 21, and the BJ term surrender, meaning to fold before playing the full hand and losing half your bet. So, we never quit, we'll end up with a buck or tag soup. What do you think? Corny, but its the start of what I hope will be many more ideas from you guys!
