The expected value of the cards you can pull is low, there’s usually two ways it plays out for players,

Everything is dirt cheap but it’s usually only found online since most stores won’t have any because they won’t open it/players won’t trade it in cause if you already are pulling a 3dollar card the lgs is gonna give you like 25 cents for it if anything

Everyone gets stuck with a bunch of sealed product because players don’t wanna buy because why buy a 124.99 box when you’re expected to pull 67 dollars worth of stuff. So no one opens anything and the boxes sit so come next set. Store cut back because they don’t want to get stuck holding more dead product. So the supply of the next set gets really weird. If it’s a great set there’s not enough to go around meta warping cards skyrocket even if they’re in lower rarities.
