Be it Sports Cards, Pokmon Cards, or Magic: The Gathering Cards, the thrill of discovering a rare and valuable treasure is unparalleled
Although not all cards are valued at quite that much, it still shows that there is a player-based market involving hundreds of millions (according to reddit, almost 3 billion) dollars worth of cards
Obviously the distinction here is somewhat arbitrary but I had too many cards to dump in at once
Combine it with an Amulet of Vigor, and you can use the treasure straight aways to cast the new cards
So it's not that unbalanced in my experience, but the opportunity to draft a dud deck is greater than most other Standard sets
This relative lack of popularity generally means that core set staples tend to trend a little bit higher than the best cards from the fall or winter sets
