In decks like Lord Windgrace and Soul of Windgrace it can work very well, targeting a Cabal Coffers, for example
Gideon Blackblade Gideon Jura Gideon of the Trials Gideon, Ally of Zendikar Gideon, Battle-Forged Gideon, Champion of Justice Gideon, Martial Paragon Gideon, the Oathsworn
As the name would suggest, they're also for use in the Commander game type, which can be played with multiple people at once
But even then, that combo just pulls all the basic lands out of your deck, it doesn't just flat out win the game, and certainly doesn't do so on the same turn that other players are still floundering with Cultivates and Command Spheres
