A blue creature from Magic: The Gathering's Journey Into Nyx set, Thassa's Devourer appears with an Unknown rarity and modest market demand. Collectors encounter it at a current value of $0.10, reflecting limited competitive use and easy availability. Grading or specific sales history is not noted, so condition and edition are primary drivers of individual card price. It fits into casual and thematic Thassa collections rather than high-end speculation.
