My favorite land! But now I use Watery Grave. It's gettin' really expensive to use with the trade loss. I'll take my deck building ability with the choice. But if you can hold on to the cards, congrats!

Don'y know about it being the best. I always like tundra. Can't beat being able to play counterspell, disenchant, swords to plowshare, ancrestral recall...... Can go on and on. Love this card too.... Hymn to tourach, pox, mana drain to second turn yawgmoths bargain..... Guess what I'm saying is I love dual lands.

The most overpriced dual land on the market, but I can see some reasoning behind it. Black/Blue is perhaps the most potent color combination in regard to control and flexibility, which is what sets it so far apart in price from the other classic duals. A must have playset for any serious magic player.

There are no lands in the game like the dual lands, especially the Underground Sea. These lands are essential for any serious Type 1-1.5 deck.

The best of all the dual lands, Create's for great control. Also good for the black search out cards. Any serious vintage control deck has four of these.

I don't know what it is about this card, but I have loved it since day 1. I started playing blue/black just because I liked having these in the deck. Odd reason for deck choice I know, but its true.

Great as are the other dual lands! Black and blue can make for a very nice combo, in which this card fits into flawlessly. The the art of this card is beautiful, and mysterious. Who knows what lurks under the waves of an underground sea? What long forgotten, untold wonders await on its shores and archipelagos.
