Underground Sea
1993 Limited Edition Beta
Underground Sea from Beta is one of the most iconic and sought-after dual lands in all of Magic: The Gathering. It taps for both Blue and Black mana without entering the battlefield tapped, making it a cornerstone of Legacy and Vintage formats. Beta copies are distinguished by their rounded corners and are significantly rarer than Unlimited printings, commanding a substantial premium.
Strong hold or buy on dips — The most valuable dual land in Magic. Alpha and Beta copies in PSA 9 regularly trade above $10,000 — treat them as collectibles first, playables second. Revised copies are the entry point for Legacy players and represent strong long-term holds. A staple in every blue-black Legacy strategy including Grixis Delver, BUG Depths, and Reanimator. Demand is permanent — this card will never be reprinted in a tournament-legal form.
