Hohoho! If you hover over the cards, the value isn't exactly what you can buy them for, they actually might be +/- 20% due to the way things are set up. There's a box that says "Group", if you click that and then choose "Custom", it will group the cards the way I want you to see them.
If you see the one, click on the card. If the card was under any version, then all you need to do is click on the price under TCG player and it will bring you to another site. Scroll down and choose one that is marked as "Near Mint" or "Lightly Played", then go to the shopping cart to finish things off.
If it was a specific version, then the process is similar to the first part. After you click on the TCG player link, click on the "View All Versions" link that is placed to the right of the card image. Lastly, you have to match what looks closest to the image displayed above this description box. Then repeating the same final touches as mentioned earlier.
(If you're feeling SUPER adventurous, some cards have foil options, you can filter for them after you're on the TCG player site. If you scroll down a little, on the left under "Printings" is a "Foil" option, and BOOM filtration is done and the new results are only the foil cards.)
Otherwise, here's some links for some FANCY cards (There are a handful that aren't to my taste or I already have, but Max should be able to help with that.):
Kaladesh
Zendikar
Amonket
