Tarot cards can be opened as well, they’re gateways, so that’s why I advise people keep them wrapped in baking foil or in a sealed metal tin, at least if they’re having the kinds of problems an open and uncontrolled gateway could be part of.
Since Tarot cards open easily for you (it seems) you may want to look into pathwalking them, things like that?
