Return of the King
All-Star Superman isn't canon.
And yes, Superman does have an practically perfect sense of memory and boasts great intelligence. But he doesn't spontaneously develop new mutations in the midst of combat. You're making it seem like the guy's a Pokemon or something.
And really? "Fodder" magic? Thor's mid-tiered magic based attacks would be troublesome for Superman, let alone his higher end stuff. Even if you think Superman would win in the end, it wouldn't be a cakewalk.
And per your own ABC logic a while ago - Superman can beat Hulk, who has beat Thor, therefore Superman should beat Thor - I find it baffling that you think Silver Surfer would pose a greater threat to Superman when Thor's historically always fared better against Norrin than vice versa.
Strange is pretty much the epitome of glass cannon in comic books as well. Him taking out Superman is just as likely as Superman flexing his muscles at him and making him faint.
