Moon Knight for those who can aim. Scott Summers is a good starter hero since to master him you need to learn every nook and corner of every map (otherwise your ricochets won’t be that effective) and develop a great gamesense (or you will always fail your ultimate). If you ain’t scared of those challenges, Cyclops is hella fun to play!
