His claims are based on his observation that the tricks would be impossible to do unless the magicians had made unholy pacts with the Devil.
His claims are based on his lack of knowledge of how magicians perform their illusions!
I'm not generally in favour of exposing methods but in this context it seems appropriate. You may be interested to take a look at this series that exposes how many magic tricks are performed.

I've been a fan of magic since I was a kid. My father had a book that explained some stage magic and I've always had a fascination with the methods used. To my recollection there is only one illusion I have seen for which I don't have a workable explanation of the method.
I can very assuredly assert that NO magic tricks require anything other than the skill of the magician and equipment, and I would assert that anyone could perform the illusions if they had the knowledge, dexterity, and equipment. Stage craft and artistic flair are another matter though.
While I'm on the topic I'll share with you two of my favourite card trick performances. Note that it's not just about the skill of the magician, it's about the performance and how the magician involves and engages the audience. It's not about fooling people and making them feel stupid, it's about evoking and sharing an experience of childlike wonder. There's an art to that!
