Field of Ruin
T: Add C to your mana pool
2, T, Sacrifice Field of Ruin: Destroy target nonbasic land. Each player searches his or her library for a basic land card and puts it onto the battlefield, then shuffles his or her library.
Anyone who plays ghost quarter should take notice of this, because I suspect there are lists where this is better. Yes it is more costly at 2 for activation, but you do get one back untapped right away. That can do things like trigger landfall or get you untapped mana of an off color.
I suspect this is better in a lot of workshop matches as well. Often you are hitting an opponent with wastelands at a hit to your own tempo, and if you are still under a sphere you may not be able to spend your mana anyway, where with this it cannot be touched by a sphere and will help you tempo up against them.
