In Edit Unit, you can form 4 sets of 4 teams (units). Each set corresponds to an element just to allow you to customize teams based on the Elemental Hall element of the day, but in reality you can choose any of those 4 sets during the EH battle.... for veterans who only need 1-2 teams to handle the EH, they can just focus on adjusting 1 or 2 sets and ignore the other 2, and new players who have such limited cards that they really can't make element-specific teams can also make just 1 or 2 versions of their teams.

The hint the game gives you is that the cards that match the EH element get a defense boost during battle.
