A Team is a group of dragons that share the same Skill. Collecting at least two dragons from the same Team activates a power boost, with each member boosting a different stat. This stat increases when the dragon is Empowered. Collecting and Empowering more Team members increases the overall boost, but selling a dragon from the Team will cause the associated boost to be removed.

You can check if a dragon belongs to a Team and see its Team members by visiting the Feed Screen.
