I have a question on Illyriel (Action: At the beginning of your turn, return one target unit to its owner's hand unless its owner pays you two resources).
From this wording, I assume that I can play Illyriel on my own units at the beginning of my turn, e.g. to get rid of unwelcome attachment (diseases etc.), since they would leave play too or e.g. to trigger leave play effects. Is this correct?
