Text (VI+errata): {Tap}: Add one mana of any color to your mana pool. During your next untap step, as you untap your permanents, return ~this~ to its owner's hand. [Oracle 2009/07/08]
Only returns to owner's hand if it is still in play at the beginning of your next untap step. [D'Angelo 2006/01/20]
It will return even if some other player now controls the land. [D'Angelo 2006/01/20]
It will return even if some effect prevents you from untapping it. The ability is not replacing the untapping of the land in any way. [DeLaney 2000/01/16]
