What occurs when two zones are exchanged and one is empty?

When two zones are exchanged, even if one of them is empty, the process involves the complete transfer of all cards from both zones. This means that the contents of each zone are swapped in their entirety. Therefore, if one zone has cards and the other is empty, the empty zone will still be filled with the cards from the non-empty zone, while the non-empty zone will become empty as a result of this exchange.

The situation aligns with the rules that dictate how zone exchanges operate in Magic: The Gathering, which encompasses all cards and components of both zones involved. The principle emphasizes that every card, regardless of whether it is empty or not, fully participates in the exchange. Hence, after the exchange, both zones will reflect the new arrangement according to the original contents of each.

This comprehensive understanding of how zone exchanges function allows players and judges to accurately assess any resulting changes in gameplay or strategy.
