Prey Upon is a creature combat trick from Magic: The Gathering’s Innistrad set that grants temporary power to a creature equal to another creature’s power while forcing it to block. Listed with an Unknown rarity and a current market value of $0.09, it occupies the lower-priced end of Innistrad singles. Collectors and players often view it as a niche pick for themed or budget aggressive decks rather than a high-demand staple. Condition and edition can affect individual sale prices.
