No, the five cards that show up on your main page is NOT your front line cards. Recommended attack front line is automatic; if you don't create a FL manually, it will default to the automatic recommendation.

To create a new FL, select the "create front line" tab. Then select the 5 cards you want in your FL by "select card". It will automatically slot the 5 cards you've chosen into your new FL.

"Copy" button is used to copy an existing FL and "proceed" button is to confirm you want to create a duplicate FL that you selected. If you did this correctly, you will see 2 FL that have the same cards.

Just play around with it using trial and error, and you'll soon understand how it works. Just delete any FL you've created by selecting the "delete" button and you'll erase the FL. Don't worry, cards won't be deleted (that's a different explanation and location in the game to do this).
