"What is the best tarot deck for beginners?"
Rethinking the standard answer.
There is no one specific route to mastering the tarot- any anyone who implies there is should be met with disbelief and a handwave. In the end, tarot is a personal journey and the only thing that can be promised is that continued practice builds skill. How you learn and practice, is your choice! These are strategies that have worked wonders for me.
