The Liber T is different and if you click with the artwork, you'll never regret it - its not pure Thoth, although the Thothy elements are there, its not RWS - it is a deck that makes you want to reach past what can sometimes be harsh artwork - at first glance, this looks like a deck that will never be readable and this is what people see first, then they give up.
But this is a deck that is so user-friendly that it beggars belief - it spoke to me and I've struggled with just the RWS and clone decks for years. I love the Liber T because it can be used at its most basic - you can just use it with keywords - but sooner or later it will try to move you on and you will have flashes of intuition, little ones at first or one of the little scenes on the card you're looking at will seem relevant.
Scion said that the designs on the cards are drawn to increase and even start intuition and having used this deck for a while now, I think this too. I still struggle with other decks, even the Thoth but using the Liber T is like having an old friend.
