Greetings, @cauam
Sorry for the inconvenience.
Unfortunately we can not de-evolve pokemon due to technical restrictions with the tools, the same comes with the iv's, gender, nature or ability of the pokemon, i hope you understand it and if we couldnt would be unfair do it just for you and not for the other users what got the same problem and got a reject on their requests for the same thing.
I hope you understand it.
have a great day,
Nezuko
