I think it would depend on how you read in order to know if they'd be helpful as a first deck.
If you're seeking a lot of structure, like Tarot offers, then the Faeries may not provide that for you.
If you read by intuition more than standardized meanings, the Faeries can be a very very good deck to work with.
The best thing about the deck, as a beginner, is you can absolutely pick up this deck and start using it and not need to know what all the cards mean first.
It is *extremely* helpful to do the exercises in the beginning of the book. The ideas presented there provide a nice approach to the cards and how to think about them when you work with them.
And, last but not least, have you felt any inclinations towards Faery lore before? Do you have an established "relationship" to the faery realm, so to speak -- how you might picture it in your head, or how it/They interacts with your real world. (Mine are constantly stealing stuff!)
Best of luck to you once your Faeries arrive and I hope you enjoy Their presence as much as I do mine
