Energy doesn't much factor into my tarot paradigm but I have a sort of reset ritual that I try to do at least once a month with decks I work regularly with. It takes some time but it feels worth it to me.
First, I go to a quiet space (but this sometimes involves music) and go through my deck, putting my cards in order and physically clean them with a (dry… obviously) cloth used for cleaning glasses. Then, I construct Jodorowsky's tarot mandala (but really, any construct using all 78 cards will do), reflecting on each card as I lay it down. After construction, I meditate on the deck as a whole for a while before deconstructing the mandala into 16 piles, (the fool, one pile for each number (with Trumps 1-10 & 11-21 (ex: Aces, Magician, Strength), each court rank and the world ), combine piles (in order) and then shuffle my deck 78 times (with my eyes closed), reflecting on an individual card for each shuffle. After this, I set the deck aside until I'm ready to read with it again.
