The card that portends doom is the Tower, usually. There are as many interpretations of Tarot as there are folks that read it, but Death usually means “change.”

Tarot is largely harmless; it’s odd how upset folks on Lemmy get over it. It’s mostly middle aged women and queer men who do it for fun. I use it as a way of organizing my thoughts sometimes - I own a few decks which I enjoy as art pieces and brainstorming tools. I’ll read for friends sometimes and I’m pretty open about the fact that I’m mostly leaning on what the cards do in the Binding of Isaac.
