When former Air Force pilot Carol Danvers was caught in the explosion of an alien Kree device, her genetic structure was radically reshaped. Boasting powers of flight, super-strength, and energy manipulation, she became the super hero Ms. Marvel. Carol soon joined the Avengers, and despite some personal challenges she has served as a stalwart member of that team several times over the years.Marvel Source
After the last update, Ms. Marvel is one the best tank in the game and she is most likely the best DPS after Dr. Strange. There is no "way" to play her. She will have no problem taking down anything outside of Cosmics. For cosmics, get all her Uniques and blessed artifacts and you should be cruising through even Kurse and Doom.
