size of yugioh card OFFICIAL KONAMI DARK SIDE DIMENSIONS SLEEVES (YUGIOH SIZE) 50ct with 9 cards per booster pack. are yugioh and pokemon cards

Many cards feature the Lost Zone mechanic, like Colresss Experiment [Lost Origin], and have a risk/reward playstyle

This effect alone puts it ahead of the other simpler Steel-type Pokemon in Space-Time Smackdown since it allows Bronzong to last longer while your opponent is smacking into it

That on top of being on the Reserved List led to its price spiking very high because of the desire for such a unique card that highlights the early days of Magic card design

Parallax Tide Market Price: $18.64, Foil: $105.75 An extremely unusual card, this enchantment is one of five cards from Nemesis with Parallax in its name, which represented powerful cards that dealt with the fading mechanic

Once the outwardly ridiculous price point is established, adherence to it takes on its own value, whether thats the markets price on an official token or a self-imposed value (as in the Hamtaro example)
