1. Something like Unito will sync cards between boards, with 
2. Using Trello automation can link cards together and sync information.
   See this article:

Let me know if you are keen to explore how to do option 2 and I'll put up some example automations

Yes please, if you could guide me for option 2. I will be very grateful.

First of all, you have to link the cards together.

For this example, I'm going to copy a card and link them together in a parent/child way:

Rule 1

When a card is added to list "List 1", copy the card into list "List 2" and link the cards together

Rule 2 - To post comments

When a comment is added to a card, find the first card linked in attachments and post comment, "{commenttext} was posted on {triggercardlink}

Rule 3 - To mirror custom fields #

When the custom field [custom field name] is set, find the first card linked in attachments and set custom field [custom field name] to {customfieldvalue}

Hi, can't I just mirror everything in two cards on different boards without using unito or power ups? Just by using trello automation.

That's what my example shows. You can technically mirror any data with automation, only things that are tricky to mirror are attachments

Ok, thank you.
