# Karplusan Forest Karplusan Forest is a dual land that produces red or green mana while dealing damage to its controller, making it a classic pain land design. Collectors value it primarily for constructed playability in red-green decks across multiple formats, where the life loss is often acceptable given the mana consistency it provides. The Dominaria United printing represents a modern reprint of this established utility land. Collectors typically pursue it as a functional staple rather than a chase card, though the foil variant appeals to those building premium versions of their decks. The nonfoil version remains the more accessible option for players prioritizing playability over presentation.
