Rule 603.7b
Official source text from the 19 June 2026 Rules release
A delayed triggered ability will trigger only once—the next time its trigger event occurs—unless it has a stated duration, such as “this turn.” If its trigger event occurs more than once simultaneously and the ability doesn’t have a stated duration, the controller of the delayed triggered ability chooses which event causes the ability to trigger.
