He could also learn about different magical cultures from Merlin's vast experience.
Well, Harry could become an even more powerful wizard. Merlin is known for his great magic skills. He might teach Harry some ancient spells that are long forgotten in the wizarding world of Harry's time. This could give Harry an edge against Voldemort or any other dark forces.
