This article is about the gameplay term. For other uses, see: Owner (disambiguation).

When you start a Duel, you are the owner of all the cards in your Extra Deck, Main Deck, Side Deck, and during the Duel, the cards in your Graveyard. While your opponent may become the controller of one of your cards (such as through "Relinquished", "Brain Control" or "Change of Heart"), they can never become the owner. If a card is sent from the field to the Hand, Deck, Graveyard, is banished, etc., these cards always go to their owner's zone, even if they were controlled by another player.
