I agree with Cedars and Agata. I usually thank the deck and just  put it back in its box. I just clean it when it starts feeling "heavy" or when I feel it needs cleansing. For that I light an incense stick (usually sandal) and pass each card through the smoke. But I've only done this once a year or less.

I think it all depends on how often you use your deck and what the reading was like. Putting the deck back in order removes any possibility of the same cards recurring unless they are the right cards, no bad shuffling reasons lol.  I smudge when the deck feels sticky, or heavy, or I use a crystal or a breath of light to clear them  Fascinating how many rituals there are  that some people use when it comes to Tarot.

Isnt that so Cas?

Sometimes I Reiki mine.
Sometimes I fan and blow on them.
Sometimes I use the pendulum.

But, am not obsessed to doing it right after every reading.

As to the idea of putting all the cards back in their numerical order........hmmmmmm....... too much work if you ask me.
I have had a case of one querent getting the very same cards as the previous one. I reshuffled the cards vigorously and also asked the querent to shuffle it (which I dont usually ask them to do) and carried on with their reading. I believe spirit will bring out the cards as they are meant to be.
