Lolno. I ran the calcs. I wouldn't have brought this up if he went down easily. Run them yourself if you want.
Steel is a lackluster attack type and its coverage is redundant alongside Fighting, while Shadow Ball hits the Ghost and Physic types for supereffective damage.Is Flash Cannon worth a mention on the Nasty Plot set? It actually has pretty good neutral coverage with Aura Sphere, and hits things for 120 BP. That's only a little less than a 160 BP Shadow Ball against Ghosts and Psychics, and its much better against everything else.
