Even more depressing, a full half of the mythics are worth less than $3, meaning that even if you manage to crack a mythic in your booster pack, you only have a coin-flip chance at making your money back
Meanwhile, some are incredibly underused and could really do with a comeback in the near future.
Based on the latest market prices tracked on TCG Stacked, Tectonic Split is worth about $3.09 USD for a regular copy and $4.57 USD for a foil copy
Meanwhile, even though its technically NOT a reprint since its coming out in The Lost Caverns of Ixalan , but getting a copy of Brasss Tunnel Grinder is awesome
Makes you wonder how many more of these promotional or test cards are out there, just waiting to be discovered
They have gold textured foil on the border and a textured, silver Pok Ball on the text block area of the card
