Or you could just take a look at the most expensive MTG cards of all time.
Sellers should clearly identify damages or defects within the item description of their listing
For perspective, the difference between the cheapest Standard deck in the meta and the cheapest Legacy deck in the meta is roughly $2,000
Sunforger, Angelfire Crusader, and Desolation Giant don't count
The artworks of all of these are amazing, and if I would ever be forced to be in a position to choose between stopping my Pikachu collection or FA Supporter collection (Im going to assume that wont happen, but in theory), I would continue with my FA Supporter collection
Im not sure itll come up often enough to outweigh the fact you get a 5/4 Flyer for sticking to the small print
