Hello Amayura,
For getting to know a deck in depth, I strongly recommand the Exercises in Alison Cross book Tarot Kaizen. The whole point of the book is to get to know a deck really well, to dig deep. Plus, the exercises are fun, and it does not take a long time each day.
For choosing wich deck to start with, I suggest doing the first two exercises of the book with all of your decks. It can take you about 15 mn for each deck, and it will really help you consider wich deck you want to dig in right now, and wich deck will be better if you let it simmer a while longer before getting into it.
The fact that some decks have no LWB is usually not a problem for me, since I mostly do not use LWB nor companion books, exept when the companion book brings something really new (like the Tarot of Prague companion book wich bring a lot of additional information about the city of Prague for example). Or when a card derives so strongly from traditional interpretation, that I have difficulty making out what it tells me and need to read what the artist intended, to fully understand the card (that is the case for a few cards from the Chrysalis tarot, for example. I suppose it would be the case with the Mary-El tarot also, though this deck is so fully different than a traditional deck, that you could also read it like an oracle, without LWB, just trusting your intuition)
By the way, the Tarot Kaizen book will help you a lot with understanding the meaning of the cards from any deck, with or without LWB. The Tarot Kaizen workbook is really great in helping to fully understand a deck.
Also, what is super interesting to do when you have several decks at your disposal, is to compare the same card from different decks. For me, this has really deepens my understanding of cards. So that also can help you, especially if there is a deck that is a little more difficult to understand and you dont have the relevant LWB. Compare the card with the same cards from other decks, eventually read some general book knowledge about the card in question (from both RWS and Thoth points of view), and you will gain a lot of useful information and understanding.
I hope you are having a blast with your 16 decks ! Enjoy !
I think comparing cards from different decks is really good. I do that too and it really helps understanding the cards better.
