[HERE] is a tutorial on how to make a legal-looking pokemon with pokesav and [HERE] is a good pokedex for you to know what moves a pokemon should have at a certain level.
I don't know if the video is good cuz I didn't really use any tutorial when I firstly used Pokesav. I got it on my own but if I start explaining I'll have to write 1 hour >_<
Good luck and if you need any help, tell me :]
