Mewtwo's tuff but your even more prove him by catching him yeah! Your Lucky I also added something to this cheat! But To get Suicune Start your pokemon adventure with Charmander. For Entei start you pokemon adventure with bulbasaur. For Raikou start your pokemon adventure with squirtle. Note: If you call any of these Legendaries you don't have a second chance. so save before battling them.
