Magic Eraser is equal to 1500-2000 grit sandpaper. It would definitely take the shine off a new set of balls, even the new heat vitrified ones. With new ball sets now retailing over $250, I wouldn't recommend anything other than Aramith Ball Restorer or Cleaner to protect that investment.
On a worn out set with nothing to lose, it could be the first step if Aramith Ball Restorer didn't work well enough.

Actually they are a micro-abrasive. Basically a glass hard resin that is processed into foam. It can be hard on some surfaces. I would think it would take shine off pool balls. Y/N??
