LOL@ people who still think that Superman auto-loses to anyone with magic despite the fact that he's beaten characters using it plenty of times. But, it's Carver so what do you expect?
As I've explained in detail in Superman vs Thor thread, Superman's supposed "magic weakness" is not really a weakness but more of a vulnerability. Kryptonite and red sun radiation are weaknesses that are specific to Superman but magic is most certainly not contrary to what a lot of people mistakenly believe. Characters that don't have any kind of innate magical resistance like Wonder Woman does, for instance, are just as vulnerable to magic as Superman. In other words, Superman is no more vulnerable to magic than Hulk is or any other character without magical resistance.
The only reason so many people mistakenly think magic is a specific Superman weakness is because it's one of the very few things that can actually hurt him because it bypasses his protective bio-field aura. But, it doesn't hurt him anymore than it does a character like Hulk or Thing, for example.
