How strong are the three witches in the quarry of God?

For the eternal three witches in the Marvel universe, their settings are actually similar to those of Visanti, the Trinity of Marvel comic masters, and they all appear in groups. The classic story in comics is in Thanos's single comic "Thanos".

The three witches in Marvel comics are Morgan Lefeby, Charming Witch and Crimson Witch. Morgan Lefeby is a character in American Marvel comics and one of the strongest witches in the history of the earth. She made her debut in the first issue of The Black Knight (1955 May).
