I am needing advice and instructions on how to get Scyther's egg move Razor Wind
No Pokemon can really learn razor wind in GSC. If you want a razor wind Scyther without hacking, then you need to use the TM02 on Butterfree or Venomoth in Generation 1, transfer it to GSC, and hope it comes out male. If it's male, then you can breed it with a female Scyther or Scizor to get a razor wind Scyther. source
