In this way, your pokemon need a priority move. Let me show you my tip, 5 Mismagius lv60+, use Perish Song => Protect => Memento => your pokemon. That all, fast and does not need priority move :))))
This is my Feebas, I trade it when it hold Prism Scale but it does not work. I read the information in https://wiki.pokemonrevolution.net/index.php?title=Feebas and it said that "It evolves into Milotic when traded while holding a Prism Scale", not mention about other status. Please help me check it or it is too ugly to evolve :)))))))
