PKHeX Pokemon exchange Revise (BDSP)

[030]

How can I modify it, I have tried several times but it is not legal

Don't create Pokemon from scratch, grab them from the encounter database (Tools > Data) and modify them as you need.

Pokemon Link is not a valid met location for Scyther/Scizor. To make a Pokemon look like it evolved during trade just change the species and fill the Latest (not OT) Handler fields.
