Resolving an action without checking for reactions
Ruling issued on November 17th 2024

Situation:
Another player plays an action. You have a reaction that causes the action to fail. However, they begin resolving the action right away, without giving you a chance to react. What should you do?

Ruling:
It is the other player's responsibility to check if anyone has a reaction before resolving their action. You should ask them to stop and play your reaction. Once you've played it, their action fails. Any steps taken as part of resolving the action must be undone.
