When an opponent uses Possession on my unit and then either I Rebuke it or they use Retreat on it, does the unit return to my hand as the owner? Does Retreat also give me the exhausted rune?

Ruling: When a possessed unit is returned to hand (whether by Rebuke or Retreat), it returns to the owner's hand, not the controller's hand. If the controller uses Retreat on a possessed unit, the owner gets the unit back and also receives 1 rune exhausted.

Nuances:

• This applies regardless of whether the owner or controller triggers the return-to-hand effect
• The Retreat benefit (1 rune exhausted) goes to the owner, not the player who cast Retreat
