I feel like Tony would find nasuverse magic and magecraft much more agreeable than his universe's magic. I mean, it makes sense since Nasuverse mages don't discredit technology completely like the HP wizards. They admit that magic and magecraft can do the same things science can do but without technology. But of coarse, True Magic is different but it can just be explained off as IRL cheat codes. In other words, Nasuverse magic is basically just technology we don't understand. Which is something Tony already believes in.
