One more thing, just a tip -- If you are going to use it as a study deck, you may find it worth your time to scan all the cards at a high resolution. I find tarot SO MUCH EASIER to study in detail when I have big, high quality digital copies to look at. It's easier to spot the minutia that I wouldn't see on the physical cards in hand.
I like this idea a lot!
For me, the only difference between my reference decks and reading decks is that my reference decks are ordered so I can easily find any card I'm looking for. Regular decks are left shuffled. So if I intended to turn a deck from reading to reference, all I need to to is reorder the cards.
That's it. I don't change their bags, or put them through rituals, or tell them what I'm doing. (Nor do I sleep with them at the foot of the bed, LOL!)
