No, because I know miracles have ceased, aside from prayer. It is the same as not going to look if someone claims Jesus returned and He's out in the field. You don't need to learn how they play out thier trickery. Even if it was real (which it's not), so what! Poop is real, cancer is real. Just because something is real doesn't mean its beneficial for you to examine it.
You already know thier intention (which isn't from God). Like Colossians 2:18 says, they go into great detail, seeming spiritual, but they are unspiritual. You will know them by thier fruit. Galatians 5 speaks of the fruits of the Spirit and the fruits of those who are of the devil.
They decieve many, but if they really had power they'd go free those in hospitals, Christ would. Deceivers deceive many, but one who studied enough to know the truth cannot be deceived.
