cards, the value of Majestys Fiend depends on a few consistent factors: its rarity, the printing and finish (regular or foil), its physical condition, and the set it was printed in (Duel Devastator)

The ability can be something simple and short-term, like a pump until the end of a turn on cards such as Akoum Hellhound and Kazandu Mammoth
Pokmon keeps a lot of its cards inexpensive with many separate variations and making its chase holofoils and art cards focus more on collectability than playability, but sometimes cards that are both competitive and expensive like Mew VMAX can slip through the cracks and cost around $20.00 per copy
