This is pretty good. The HP to MCU crossover part isn't very original, but it's original in that the Wizard that's crossed over is an OC that we don't know much about, and seems to be a pureblood based on his reaction to muggle stuff. The only downside I can see so far is that the grammar isn't very good, but still better than many fanfics on this app.
