When trying this nothing happen to main card.

Trigger

'QA-TPI'

is archived

Action

remove the light lime

'TPI'

label from the card

post comment

Any help is appreciated.

Hi @Shindlay Nath ,

Interesting use case that there isn't an automation option for as the automation triggers don't have filters for mirror cards...@Caity 

As a work around, you can do this:

when a card with a name starting with "https://trello.com/c" is archived, find a card with link "{triggercardname}", remove the light lime "TPI" label from the card and post comment "TPI is arranged"

The devil is in the detail, notice that the cascade option is find a card with link  and the variable {triggercardname}

Thank you So much Mike

Thanks @Mike - Dreamsuite Consulting! You can make this even simpler:

when a card is archived, find the source card...

...and the on from there.

"Find the source card" is an option in the "Cascade" tab, and it will only run if the trigger card is a Mirror card.

That is what @Shindlay Nath did originally and it didn't work.

I have tested and it does work for me however.
