Eh, Magnezone and Shanderaa are two things though. And all you need to kill them after they take care of Nattorei is well... a Shanderaa, since Shanderaa will be locked into his Fire attack if it's scarfed, and Magnezone will as well, otherwise he wouldn't outrun Shanderaa anyway. So...
Shanderaa
Burunkeru
Nuttre
