Prediction: Both fighters are extreme examples of what a magician can accomplish, but Doctor Fate should win by a small margin. The main reason is that Doctor Fate’s magic is chant-less and doesn’t require hand movements like Dr. Strange’s magic. Even if Dr. Strange were to remove Doctor Fate’s helmet, Doctor Fate can still use magic and survive most attacks until his helmet returns.
Winner: Doctor Fate
