Bought one copy solely for the trading purpose.
This card is powerful in play and iconic in art and meaning (it's famous and admired, precious thing with great power; leads it's owners to decadency and corruption).
I think it's destined to raise in price, unless Wizards of the Coast ban it from Modern and/or EDH formats. Going to wait for about 20 years and see the price change. Wish me luck if You can. :)
Until then it's safely secured in a card binder, in a protective foil.
If I earn a lot, part of it will be spent on Buddhism & Wicca.
