I traded a scizor with a friend to evolve it but it seems locked to him and I can't get it back I would like to have my scizor back since it is one of the pillars of my team My name is: Yuyute My frinds names is: Theress Server: Silver I can't provide evidence of our agreement since it was a verbal agreement, but I already returned his pokemon and now I just want to get mine back
