This is one of many tools Satan uses to gain access to people. Using Tarot Cards is a form of divination which the Bible forbids.
“10 There shall not be found among you any one that maketh his son or his daughter to pass through the fire, or that useth divination, or an observer of times, or an enchanter, or a witch, 11 or a charmer, or a consulter with familiar spirits, or a wizard, or a necromancer. 12 For all that do these things are an abomination unto the Lord: and because of these abominations the Lord thy God doth drive them out from before thee. 13 Thou shalt be perfect with the Lord thy God.”
