my cat is all up in my business EVERY time i use my tarot cards why?

firstly i do not have an issue with my cat being interested in what i’m doing, but it seems like every time i use my deck and crystals he shows up at my bed room door, and meows until i let him in. when i let him in he instantly starts walking all over my cards and rubbing his face on my crystals while purring extremely loud. its about the same amount of interest as i get annoyance from this LOL does anyone know WHY he does this?
