Deranged Whelp appears in Magic: The Gathering's Eldritch Moon set as an Unknown rarity creature with a current market value of $0.06. Collectors and budget players often view it as a low-cost filler for casual black decks or as part of bulk lots from the set. Its modest price reflects limited demand and common circulation compared with higher-tier Eldritch Moon cards. Availability is generally high, making it easy to source for set-completion or casual play.
