When I first got into vintage, I did dip into this singles for a short while. Most of these are just random cards, it's hard to stick to a specific card you enjoy, especially if it's AoS.
I stopped because, I realize that the price per card is actually much more than the deck itself. Some of those rarer designs, and brown or green cards, could get up to $20 per card. If it was, for example a brown Best Bower joker, I'm thinking it might break $100.
But @jmrock, you've got some sick design singles there! I'm sure you've got more than 20 right?
