What to write about

A few common reasons people reach out:

  • Bug reports — something broken, wrong card data, missing images
  • Feature ideas — new tools, filters, analyses you'd love to see
  • Archetype or deck questions — if something in the meta dashboard doesn't look right
  • Privacy, data, or account requests — please include the email tied to your account (see the Privacy Policy for the full list of rights)
