Can I create a rule that will gather all mirrored cards into a list when the original card is marked

[Mark Knight]

Can I create a rule that will gather all mirrored cards into a list when the original card is marked completed or alternatively archive all mirrored cards when the original is marked completed. I appreciate that marking a mirrored card complete will mark the original complete also and thus trigger the action.

Hi @Mark Knight, welcome to the Atlassian Community!

You can use a rule similar to this one to archive the mirror card when the original one is completed.

when the card is marked as complete in a card, find a card titled "{cardlink}" in list "List", and archive the card
