When can a Chosen Champion return to its zone?

A Chosen Champion cannot return to its zone under normal circumstances due to the specific rules governing its movement and game mechanics. In the context of Riftbound, once a Chosen Champion has been defeated or removed from play, it typically does not have a method for returning to its original zone without specific conditions being met. This reflects the nature of how champions operate within the game; they are meant to be powerful entities that, once defeated, do not readily return to the battlefield unless explicitly allowed by a card effect or game rule.

While there may be circumstances in certain games that allow characters or entities to return under particular conditions, here it emphasizes that, generally speaking, a Chosen Champion remains out of play unless a specific narrative or game mechanic indicates otherwise. This rule promotes strategic planning and management of resources during gameplay, encouraging players to consider their moves carefully and the implications of their champion choices.
