Lightning Main is in general the most less supportive character with many ninjas, especially in our meta and he is basically working with specifically formations and strategies. That's why you don't see him often in main formations of these and many new released ninjas. With Han however, he could work with the leech passive for sure, if you add reflecting, healing, buffing or supporting ninjas with him. Lightning Main is in general not the main character that will survive long time anymore, especially in other modes other than matsuri or arena.
