I really like the fanfiction 'Magic United'. In this story, the mages from 'Fairy Tail' and 'Black Clover' face a common enemy that threatens both their worlds. It shows how they can learn from each other's fighting styles. For example, the teamwork in 'Fairy Tail' influences the more individualistic mages in 'Black Clover'.
