here is the run: here is the route i used (wich i already replaced in favor of a better one):https://pastebin.com/pCLbh8Gb

This run would need a rule exception, since you cant get Mew without using a glitch. I suggest we should state that you can perform only one trainerfly/deathfly glitch to spawn a lv7 Mew. The routing is really interesting since Mew can learn every tm, but you are really underleveled compared to nidoking for example. I think this can easily sub 2
