Text (UG): Target player and each of his or her teammates exchange life totals.
You can cast this on a player with no teammates. It will do nothing, because you can't exchange one of something. [Barclay 1998/08/13]
If there is more than one teammate present, you get to choose which player gets which life total, but you must make sure that each life total goes to a different player. [QAS 1998/09/09]
All tournament formats have banned cards from Unglued.
