A block that has different sections predefined by a template that allows for quick creation of multiple cards with the same properties. For example a card block that has spaces for name, description, cost etc. for spells, so you can create an overview of spells. Absolute non plus ultra would be the card collection pages in games like Magic: The Gathering Arena or Hearthstone.

Best case would be to just click a plus sign for a new one or integrate a slash command or similar.

Tied to that an overview page with a grid layout like a file explorer.
