Great chapter, though i feel that getting your magic invisible, while awesome, is too little of a boost for being the champion of a cosmic force that can rival the Phoenix force. Maybe he could gain something like the shinigami's eyes from death note as a passive ability for being the champion of death and death magic like zeref from fairy tail? That would be nice.
Ideas for the Future you might like: Aves can visit that Mystic Order Dr. Strange is a part of, and maybe get an awesome magical artifact. The Order doesn't own these artifacts, but only store them, and most of these objects have some kind of artificial intelligence and don't allow just anyone to use them. (Like Dr.Strange's Levitation Cloak) So, my idea is that Harry might be able to find something useful to boost his power for the war with Thanos. He is the Champion of Death, and there should be some artifact related to that element. Another object Harry can target: Mystic Wakanda Herb That plant that enhances the Black Panther to become who he is. That plant is most likely not native to Earth and probably came along with the meteor that also brought Vibranium to earth. Harry can use that herb, make a powerful Elixir - and add more power to his power. It must be some kind of plant that enhances senses, reflexes, and the awareness of an individual. (picture of that Plack Panther herb)
