Wanda Maximoff has never truly been defeated, only "losing" to the combined forces of Doctor Strange, Wong, and America Chavez after realizing the error in her ways. For a time, Wanda posed the greatest threat to the Multiverse, going on a violent rampage on Earth-838.
As the Scarlet Witch, Wanda has had the ability to use Chaos Magic since birth, unknowingly using it to protect herself and her brother as children. Wanda may not be as physically strong as Thor or Hulk, but her abilities far exceed those of Avengers such as Captain America and Spider-Man.
This revelation sheds light on how Wanda uses her powers, and she needs her sense of sight to control her hexes. If there's one superhero who can totally beat her, it would be Spider-Man.
Raven would win in a fight against Scarlet Witch because her extremely potent powers as an empath can abuse Wanda's greatest weakness, her own mind. Raven and Scarlet Witch are on more or less the same level of power, and both are capable of destruction on a near-cosmic level.

However, things could go the other way around too, with the red superhero throwing Scarlet Witch off her game with his words and getting the best of her. That being said, the latter's powers are beyond the merc's control, so it's safe to say Wanda will take down Deadpool with The Darkhold.
