Changing Control

Changing Control is a keyword that appears in card effects in Mythgard. It is more of a description that an effect in itself; it explains that when control of minions is switched, the card still returns either to its owner's hand or boneyard upon being removed from play (unless Banished, presumably).

In-game description
Changing Control: Minions that change controllers still return to the original owner's hand or boneyard.
