Jesus Christ again with this Storm vs Magneto stuff let it go. Storm has fought Magneto 6 times(Canonically) and out of those 6 fights: 2 of them Storm almost kills Magneto but holds back. To which Magneto won both times. Another fight it's a Stalemate a weak Version of Magneto to which Storm failed to KO him, but was able to stalemate him. And the most recent one is Storm beating Henchmen Magneto. Yes, she won because after their fight Henshmen Magneto never shows up until the next issue which X-Legion rejuvenates him. There is no amount of excuses you could make for that instance.
Storm being a Goddess has nothing to do with anything. We don't have enough information about it anyway, other than she has been in that form 2twice.
If, we want to be realistic let's stop High-Balling and Low-Balling both characters.
