One-Card Tarot Reading
The one card tarot reading is best for times when focusing on just one thing without any potential complications is desirable. It can be used for just about any question, including to draw a card of the day, week, or even one's card of ultimate destiny. It can also be used repetitively, as some readers prefer to pull one card at a time, watching as a story unfolds. There are even some readers who don't use tarot spreads at all, relying on this method alone.
A skull and crossbones present obvious symbolism here. Something coming to an end, a necessary transition into the next stage.
Transformation, change, transitional period leading to a new way. Loss of the status quo.
