Character development is key. A good fanfic should show how Morgana and Arthur grow and change in relation to each other. For example, if Morgana starts as an antagonist, there should be a believable journey for her to become something more.
The plot should be engaging. It could be a story that explores an alternate universe where they have different roles or a plot that focuses on a specific event that changes their relationship. Maybe a magical curse that forces them to rely on each other.
