LeNormand differs from traditional tarot decks in a number of ways. The most obvious of these is the fact that the LeNormand deck only has 36 cards compared to the standard 78 in a tarot deck. For newbies, that's less than half the cards to remember. So that's one thing in its favor for new readers.
The burden, however, appears to be much more on the reader's psychic and/or medium abilities than with regular tarot. The LeNormand method encourages you to call upon your spirit guides to help with readings, and you're also encouraged to come up with your own list of meanings--keywords, really--for the cards. That's only my first impression so far, based on what I have read.
Also, it seems like reading the LeNormand cards is a lot more structured than reading tarot. There are certain layouts, like tarot, but they can be used multiple times in different ways. Seems kind of interesting to me!
Donnaleigh De LaRose does a fantastic blog on this topic that you can find here. Since I'm so new to LeNormand, I figured I'd let her explain it to you.
I received one LeNormand deck to review, and I'm definitely going to check it out and see how it works. Not sure if it will become part of my repertoire, but it never hurts to take a look at new things, right? :)
