There's no way you can write a whole lot of good songs without eventually using cards in some symbolic way somewhere. It would be pretty surprising if Dylan had not done so by this time.The Tarot deck contains symbolic codes for pretty well everything that can happen in life. The regular card deck does so too, but to a lesser extent. Card games involve a combination of conscious strategy, luck, subconscious awareness, possibly ESP, and what might be termed destiny...so cards will always be a handy metaphor for life itself.
"Gentlemen, he said, we don't need your organization, we've shined your shoes, moved your mountains, and marked your cards, but Eden is burning! Either get ready for elimination or else your hearts must have the courage of the Changing of the Guards" - Dylan
Now that's a symbolic statement from common people everywhere to the corrupt power brokers who have dominated and exploited our world through the use of guns and money. The Eden of nature is burning all around us...but the Changing of the Guards is on the way. The System must change too...or it must fall.
