Well, if you want to get technical, all human champs should be listed as metal because they have iron in their blood, and Magneto could easily affect them by stopping the flow of such or, in a more extreme measure, just rip the iron out of their bodies like reverse shrapnel.
As well as Rocket. Although some people that I know think he should and then some don’t so that’s an interesting one

That's actually not how magnetism works. If it was, MRI machines would suck your blood out of your eyeballs.Iron isn't magnetic because individual iron atoms are somehow magnetic, at least not in the way people normally think of magnetism. Iron is magnetic because in large chunks of iron the individual atoms align their spin in such a way that their weak magnetic moments reinforce each other. An individual iron atom in a hemoglobin molecule is no more magnetic than the rest of the atoms in your body.Theoretically speaking, those individual iron atoms do respond to a magnetic field, but so does every other atom in your body. If Magneto could produce a strong enough magnetic force to pull your hemoglobin towards him, he would also strip the electrons off the atoms of your body and ionize you into an explosive plasma. At that level of magnetic strength, dirt becomes magnetic. Air becomes magnetic. At this power level Magneto is no longer master of magnetism, he's master of basically all matter.
