[Scripting Question] Minior Pokemon_Forms script?

While adding the Shields Down ability, I realized that I needed a Pokemon_Forms script...
Do any of you have it?
Is it needed?
Thanks in advance

Just look at what is done for Vivillion and copy that script, but make sure that you add a check to prevent the form on creation from being "Shields Up" Form

If you are using mybuisness' version of Shield's Down then you don't even have to do that.

Better you use what I did:
