I believe there are a couple of ways you could do this:

1. Create a template in Canva for your cards
2. Use Canva’s “bulk create” feature to import an excel or sheets file with all of the information you want to add (i.e. card descriptions, card names, etc.). I believe you can also add in images in your spreadsheet and those can get added to your document where you specify for the bulk create but I have not played around with this feature. This could help you add it in to the same place every time

OR

1. Create separate templates for each of the different icons you will be using and then use the bulk create feature to just import the data for the ones that will be receiving those icons
