Emma is steadily in top five (or at least top ten) of Marvel's finest telepaths. Also where's the fight? On Marvel Earth with its tricky electromagnetic field or somewhere else?
If it's neutral zone, I can see her giving a good fight to Maxwell Lord and winning like 7-8\10. He doesn't seem to be in the same league as telepaths like Martian Manhuner or Manchester Black...though the latter is more known as adept TK user.
