Doctor Strange Re-works
Doctor Strange being Marvel's Sorcerer Supreme should be a character of awesomeness and usefulness regardless of popularity in this Marvel Contest of Champions. Perhaps a cool shield like Dormammu's and Mordo's just to start. As sorcerer supreme, Dr. Strange could have many utilities at his arsenal of mystic powers that can be controlled by the players, just like that dude with a flaming skull who has a burning motorcycle. Like if you do X then Dr. Strange will apply X (Random) to his enemies. Or if you successful intercept and enemies' X then Dr. Strange gains X (Random). I'm thinking of like Scarlet Witch, but likely more controlled with random twist.
